DETAILED DESCRIPTION

It will be readily understood that the instant components, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of at least one of a method, apparatus, computer readable storage medium and system, as represented in the attached figures, is not intended to limit the scope of the application as claimed but is merely representative of selected embodiments. Multiple embodiments depicted herein are not intended to limit the scope of the solution. The computer-readable storage medium may be a non-transitory computer readable medium or a non-transitory computer readable storage medium.
Communications between the transport(s) and certain entities, such as remote servers, other transports and local computing devices (e.g., smartphones, personal computers, transport-embedded computers, etc.) may be sent and/or received and processed by one or more ‘components’ which may be hardware, firmware, software or a combination thereof. The components may be part of any of these entities or computing devices or certain other computing devices. In one example, consensus decisions related to blockchain transactions may be performed by one or more computing devices or components (which may be any element described and/or depicted herein) associated with the transport(s) and one or more of the components outside or at a remote location from the transport(s).
The instant features, structures, or characteristics described in this specification may be combined in any suitable manner in one or more embodiments. For example, the usage of the phrases “example embodiments,” “some embodiments,” or other similar language, throughout this specification refers to the fact that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one example. Thus, appearances of the phrases “example embodiments”, “in some embodiments”, “in other embodiments,” or other similar language, throughout this specification do not necessarily all refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the diagrams, any connection between elements can permit one-way and/or two-way communication, even if the depicted connection is a one-way or two-way arrow. In the current solution, a vehicle or transport may include one or more of cars, trucks, walking area battery electric vehicle (BEV), e-Palette, fuel cell bus, motorcycles, scooters, bicycles, boats, recreational vehicles, planes, and any object that may be used to transport people and or goods from one location to another.
In addition, while the term “message” may have been used in the description of embodiments, other types of network data, such as, a packet, frame, datagram, etc. may also be used. Furthermore, while certain types of messages and signaling may be depicted in exemplary embodiments they are not limited to a certain type of message and signaling.
Example embodiments provide methods, systems, components, non-transitory computer readable medium, devices, and/or networks, which provide at least one of a transport (also referred to as a vehicle or car herein), a data collection system, a data monitoring system, a verification system, an authorization system, and a vehicle data distribution system. The vehicle status condition data received in the form of communication messages, such as wireless data network communications and/or wired communication messages, may be processed to identify vehicle/transport status conditions and provide feedback on the condition and/or changes of a transport. In one example, a user profile may be applied to a particular transport/vehicle to authorize a current vehicle event, service stops at service stations, to authorize subsequent vehicle rental services, and enable vehicle-to-vehicle communications.
Within the communication infrastructure, a decentralized database is a distributed storage system which includes multiple nodes that communicate with each other. A blockchain is an example of a decentralized database, which includes an append-only immutable data structure (i.e., a distributed ledger) capable of maintaining records between untrusted parties. The untrusted parties are referred to herein as peers, nodes, or peer nodes. Each peer maintains a copy of the database records, and no single peer can modify the database records without a consensus being reached among the distributed peers. For example, the peers may execute a consensus protocol to validate blockchain storage entries, group the storage entries into blocks, and build a hash chain via the blocks. This process forms the ledger by ordering the storage entries, as is necessary, for consistency. In public or permissionless blockchains, anyone can participate without a specific identity. Public blockchains can involve crypto-currencies and use consensus-based on various protocols such as proof of work (PoW). Conversely, a permissioned blockchain database can secure interactions among a group of entities, which share a common goal, but which do not or cannot fully trust one another, such as businesses that exchange funds, goods, information, and the like. The instant solution can function in a permissioned and/or a permissionless blockchain setting.
Smart contracts are trusted distributed applications which leverage tamper-proof properties of the shared or distributed ledger (which may be in the form of a blockchain) and an underlying agreement between member nodes, which is referred to as an endorsement or endorsement policy. In general, blockchain entries are “endorsed” before being committed to the blockchain while entries, which are not endorsed are disregarded. A typical endorsement policy allows smart contract executable code to specify endorsers for an entry in the form of a set of peer nodes that are necessary for endorsement. When a client sends the entry to the peers specified in the endorsement policy, the entry is executed to validate the entry. After validation, the entries enter an ordering phase in which a consensus protocol produces an ordered sequence of endorsed entries grouped into blocks.
Nodes are the communication entities of the blockchain system. A “node” may perform a logical function in the sense that multiple nodes of different types can run on the same physical server. Nodes are grouped in trust domains and are associated with logical entities that control them in various ways. Nodes may include different types, such as a client or submitting-client node, which submits an entry-invocation to an endorser (e.g., peer), and broadcasts entry proposals to an ordering service (e.g., ordering node). Another type of node is a peer node, which can receive client submitted entries, commit the entries and maintain a state and a copy of the ledger of blockchain entries. Peers can also have the role of an endorser. An ordering-service-node or orderer is a node running the communication service for all nodes and which implements a delivery guarantee, such as a broadcast to each of the peer nodes in the system when committing entries and modifying a world state of the blockchain. The world state can constitute the initial blockchain entry, which normally includes control and setup information.
A ledger is a sequenced, tamper-resistant record of all state transitions of a blockchain. State transitions may result from smart contract executable code invocations (i.e., entries) submitted by participating parties (e.g., client nodes, ordering nodes, endorser nodes, peer nodes, etc.). An entry may result in a set of asset key-value pairs being committed to the ledger as one or more operands, such as creates, updates, deletes, and the like. The ledger includes a blockchain (also referred to as a chain), which stores an immutable, sequenced record in blocks. The ledger also includes a state database, which maintains a current state of the blockchain. There is typically one ledger per channel. Each peer node maintains a copy of the ledger for each channel of which they are a member.
A chain is an entry log structured as hash-linked blocks, and each block contains a sequence of N entries where N is equal to or greater than one. The block header includes a hash of the blocks' entries, as well as a hash of the prior block's header. In this way, all entries on the ledger may be sequenced and cryptographically linked together. Accordingly, it is not possible to tamper with the ledger data without breaking the hash links. A hash of a most recently added blockchain block represents every entry on the chain that has come before it, making it possible to ensure that all peer nodes are in a consistent and trusted state. The chain may be stored on a peer node file system (i.e., local, attached storage, cloud, etc.), efficiently supporting the append-only nature of the blockchain workload.
The current state of the immutable ledger represents the latest values for all keys that are included in the chain entry log. Since the current state represents the latest key values known to a channel, it is sometimes referred to as a world state. Smart contract executable code invocations execute entries against the current state data of the ledger. To make these smart contract executable code interactions efficient, the latest values of the keys may be stored in a state database. The state database may be simply an indexed view into the chain's entry log and can therefore be regenerated from the chain at any time. The state database may automatically be recovered (or generated if needed) upon peer node startup and before entries are accepted.
A blockchain is different from a traditional database in that the blockchain is not a central storage but rather a decentralized, immutable, and secure storage, where nodes must share in changes to records in the storage. Some properties that are inherent in blockchain and which help implement the blockchain include, but are not limited to, an immutable ledger, smart contracts, security, privacy, decentralization, consensus, endorsement, accessibility, and the like.
Example embodiments provide a service to a particular vehicle and/or a user profile that is applied to the vehicle. For example, a user may be the owner of a vehicle or the operator of a vehicle owned by another party. The vehicle may require service at certain intervals, and the service needs may require authorization before permitting the services to be received. Also, service centers may offer services to vehicles in a nearby area based on the vehicle's current route plan and a relative level of service requirements (e.g., immediate, severe, intermediate, minor, etc.). The vehicle needs may be monitored via one or more vehicle and/or road sensors or cameras, which report sensed data to a central controller computer device in and/or apart from the vehicle. This data is forwarded to a management server for review and action. A sensor may be located on one or more of the interior of the transport, the exterior of the transport, on a fixed object apart from the transport, and on another transport proximate the transport. The sensor may also be associated with the transport's speed, the transport's braking, the transport's acceleration, fuel levels, service needs, the gear-shifting of the transport, the transport's steering, and the like. A sensor, as described herein, may also be a device, such as a wireless device in and/or proximate to the transport. Also, sensor information may be used to identify whether the vehicle is operating safely and whether an occupant has engaged in any unexpected vehicle conditions, such as during a vehicle access and/or utilization period. Vehicle information collected before, during and/or after a vehicle's operation may be identified and stored in a transaction on a shared/distributed ledger, which may be generated and committed to the immutable ledger as determined by a permission granting consortium, and thus in a “decentralized” manner, such as via a blockchain membership group.
Each interested party (i.e., owner, user, company, agency, etc.) may want to limit the exposure of private information, and therefore the blockchain and its immutability can be used to manage permissions for each particular user vehicle profile. A smart contract may be used to provide compensation, quantify a user profile score/rating/review, apply vehicle event permissions, determine when service is needed, identify a collision and/or degradation event, identify a safety concern event, identify parties to the event and provide distribution to registered entities seeking access to such vehicle event data. Also, the results may be identified, and the necessary information can be shared among the registered companies and/or individuals based on a consensus approach associated with the blockchain. Such an approach could not be implemented on a traditional centralized database.
Various driving systems of the instant solution can utilize software, an array of sensors as well as machine learning functionality, light detection and ranging (Lidar) projectors, radar, ultrasonic sensors, etc. to create a map of terrain and road that a transport can use for navigation and other purposes. In some embodiments, GPS, maps, cameras, sensors and the like can also be used in autonomous vehicles in place of Lidar.
The instant solution includes, in certain embodiments, authorizing a vehicle for service via an automated and quick authentication scheme. For example, driving up to a charging station or fuel pump may be performed by a vehicle operator or an autonomous transport and the authorization to receive charge or fuel may be performed without any delays provided the authorization is received by the service and/or charging station. A vehicle may provide a communication signal that provides an identification of a vehicle that has a currently active profile linked to an account that is authorized to accept a service, which can be later rectified by compensation. Additional measures may be used to provide further authentication, such as another identifier may be sent from the user's device wirelessly to the service center to replace or supplement the first authorization effort between the transport and the service center with an additional authorization effort.
Data shared and received may be stored in a database, which maintains data in one single database (e.g., database server) and generally at one particular location. This location is often a central computer, for example, a desktop central processing unit (CPU), a server CPU, or a mainframe computer. Information stored on a centralized database is typically accessible from multiple different points. A centralized database is easy to manage, maintain, and control, especially for purposes of security because of its single location. Within a centralized database, data redundancy is minimized as a single storing place of all data also implies that a given set of data only has one primary record. A blockchain may be used for storing transport-related data and transactions.
Any of the actions described herein may be performed by one or more processors (such as a microprocessor, a sensor, an Electronic Control Unit (ECU), a head unit, and the like), with or without memory, which may be located on-board the transport and/or or off-board the transport (such as a server, computer, mobile/wireless device, etc.). The one or more processors may communicate with other memory and/or other processors on-board or off-board other transports to utilize data being sent by and/or to the transport. The one or more processors and the other processors can send data, receive data, and utilize this data to perform one or more of the actions described or depicted herein.
The instant solution uses object detection on data received from sensors in locations such as a vehicle to determine one or more occupants in a vehicle. Before the vehicle pairs with a proximate device, a validation allows the wireless pairing to be performed only when the device and/or the person associated with the device is in the vehicle, approaching the vehicle, or proximate the vehicle. This functionality validates that the system will only pair with devices that it should pair with and avoid the situation where the system connects to another device within a pairing distance when the owner of the another proximate device is not in or proximate the vehicle.
Vehicles may be paired to multiple devices, such as when more than one person occupies the vehicle and pairs with the vehicle. There are times when a vehicle will connect to a device that is proximate but not as proximate to another device that may reside inside or proximate to the vehicle. The person inside the vehicle must do one of least two things at that point. One solution is to go into the wireless settings of the vehicle, disconnect the device that is incorrectly paired and connect the desired device. Another solution is maneuvering the vehicle out of the area, thus losing the incorrect pairing and connecting with the desired device.
What is needed is a system to determine the correct device to pair to, based on at least the proximity of the device to the vehicle, a determination of the person that is most proximate to the vehicle, and a determination that the device location and/or a person associated with the device to be paired is a device that the vehicle should pair with.
FIG. 1A shows a system diagram 100 of enhanced wireless connectivity according to example embodiments. Vehicle 102 is shown with occupant 106 holding a device 108, such as a mobile device. A sensor 104 is shown that captures data from the vehicle's cabin. A location 110, such as a home, is shown with a person 112 inside the location and a device 114 proximate to person 112. A sensor 116 is depicted that captures data of the inside of the location.
Sensors in the cabin of vehicle 102 detect objects in the vehicle. These sensors may include (but are not limited to) Millimeter Wave Radar (mmWave), cameras, microphones, etc. mmWave is a particular class of radar technology that uses short-wavelength electromagnetic waves. Radar systems transmit electromagnetic wave signals that object in their path then reflect. By capturing the reflected signal, a radar system can determine the objects' range, velocity, and angle. In another example, cameras may capture data such as images and/or videos of the people in the location 110. By analysis of this data, a processor may utilize face detection software to determine the identify of the people.
Sensors 104 on vehicle 102 may scan the cabin of the vehicle. The sensors may record data and send the data to a processor in the vehicle, which may be referred to as the vehicle processor. The vehicle processor may be a central vehicle processor, such as an Electronic Control Module (ECM), a processor in the head unit of the vehicle, or the like. It may be communicably coupled to one or more other vehicle processors, including one or more processors associated with performing methods of the instant application. Vehicle processors may also be communicably coupled to the processor(s) associated with location 110, other vehicles, or servers in a remote location and communicably coupled to the system 100 via a network, such as the Internet.
In one example, a vehicle processor may transmit and receive messages through wireless communications interfaces to and from the processor in the location, servers, another vehicle, and/or occupant device(s). In another example, a vehicle processor may transmit and receive messages through wired communications interfaces (e.g., through a wired communication interface associated with a charging station connected to the vehicle, through a wired charging interface such as a universal serial bus (USB) connection for an occupant device, and the like) to and from another vehicle and/or other processors. Vehicle processors may have one or more associated memory devices for storing applications and data. They can be interconnected by various wired or wireless communications pathways, such as a Controller Area Network (CAN) bus or different wireless technologies known in the art.
The instant solution may entirely or partially execute in one or more of the processors in vehicle 102, sensors 104 on the vehicle, a network, one or more devices 108 and 114, and/or any other computer/server associated with the vehicle, such as a server associated with a manufacturer of the vehicle communicably coupled to the vehicle 102 through a network, for example.
When device 108 is determined to be approaching the vehicle, or is proximate the vehicle 102, the wireless system in the vehicle may detect a device that has previously been paired with the wireless system when the vehicle's ignition is engaged. In another example, this functionality is performed when the vehicle is not started. Before pairing with a proximate device 108, 114, the system may determine if the person associated with the device is in or is approaching vehicle 102. The system may determine the association between device 108 and person 106 to be a comparison of the distance between a location of person 106 and a location of device 108. In another example, the association between device 108 and person 106 may be through a determination of the identity of person 106 and comparing details of the identity of the person with the details of device 108. For example, the data in the identity of person 106 may include details of device 108 (e.g., MAC ID, etc.), and the data in the details of the device may include the identity of person 106. In one example, data captured by sensor 116 in location 110 is sent to a processor associated with location 110, such as a server. The server may compare the captured face data and compare the face data to stored data in a database, wherein the database may be located in location 110, or outside of the location, such as in the cloud. The system determines the identity of the person, and a determination is made that the person is associated with the device 114. This determination may be through access to a memory associated with the server containing identity data of people in location 110. The server may identify person 112 in location 110 through face detection or similar technologies. This determination may be sent to vehicle 102, which may be located proximate the location 110. In another example, using data from sensors 104 and 116, the system may determine the identity of the detected people, as further detailed herein. The system determines the location of the people both in and proximate vehicle 102 and location 110, as well as the proximity of the device 108 and 114 that is within range of the wireless connection to vehicle 102.
In one example, the vehicle processor in vehicle 102, executing the instant solution, analyzes data received by the vehicle processor from sensors 104 in the cabin of vehicle 102 and sensors 116 in location 110. The received data may be stored in memory associated with the vehicle processor and analyzed by the execution of the current solution in the vehicle processor. The vehicle processor may determine the characteristics of the objects through the analysis of the received data. This analysis may allow the processor to determine the occupant(s) in the vehicle as well as the people in location 110. If the system determines that the device in or near the vehicle is associated with a person in or near the vehicle, then pairing is allowed with that device. If the system determines that a device is within pairing distance but not in the vehicle, the pairing is not allowed. In one example, the strength of the signal received by the previously paired devices at vehicle 102 may be used to determine the proximity of the previously paired devices.
The system does not solely rely on the location of the device within a pairing distance of vehicle 102 but verifies that the person associated with the device is in or proximate the vehicle 102 before the pairing is allowed.
FIG. 1B illustrates a message flow diagram 150 according to example embodiments. As previously shown in FIG. 1A, there's a vehicle 102 equipped with sensors 104 and a location 110 equipped with sensors 116. The vehicle includes a processor 152, referred to herein as the vehicle processor, which could be an Engine Control Unit (ECU) like the Electronic Control Module (ECM) or any other type of processor within vehicle 102. This vehicle processor can connect to other processors, such as other ECUs, through a bus system like the Controller Area Network (CAN) bus. The vehicle can also communicate with external processors associated with servers, other vehicles, or locations like a home or a business. This communication may occur through wireless protocols, including cellular communication, short-range communication, or vehicle-to-vehicle communication. The vehicle can also connect to a network (not depicted), such as the Internet or a Cloud-based network. A server 176 may be present in the system. The server may be located in the cloud and may be associated with the manufacturer of vehicle 102, for example. The server may receive data from one or more of processor 152 associated with vehicle 102 and processor 156 associated with location 110. Communication between vehicle 102 and location 110 may be through a network like the Internet.
Memory 154 may be associated with processor 152 in the vehicle. This memory can store executable code, including the logic for the current solution, a table, a database, etc. The stored information in memory 154 may include data related to the characteristics of the vehicle occupants, such as data related to the face of the occupants, which may be used by processor 152 to perform face detection for the identity of the occupants.
Processor 156 is associated with location 110. This processor 156 may be located at location 110, such as part of a home computer network, and may receive data from sensors 116 at location 110. Processor 156 may also communicate with an external server 176 in the cloud, where communication between processor 156 and server 176 occurs through a network, such as the Internet.
The sensors 104 inside the vehicle's cabin 102 may be activated to scan and capture data. This activation may be performed when the vehicle is started or activated when the sensors 104 detect movement in the cabin of vehicle 102 or near vehicle 102. The types of sensors can include Millimeter Wave radars (mmWave), cameras, microphones, etc. The data captured 160 by the sensors 104 may include objects in the cabin of vehicle 102, including occupant 106. The sensors 116 in location 110 may also capture 162 data associated with people in location 110, such as occupant 112. As sensors 104 and 116 collect scanned data, the scanned data may be sent to processor 164 and processor 166, respectively. Processor 152 may store the collected data in memory 154 associated with processor 152. Likewise, sensor 116 at location 110 may send 166 the scanned data to processor 156 and store the scanned data in memory associated with processor 156, not depicted. Processor 156 at location 110 may send data 168, such as scan data of occupant 112, to processor 152 of vehicle 102. The sending of data from the location to the vehicle may be in response to a query by vehicle 102, or the scanned data may be sent at an interval, such as every minutes. In another example, sensors 104 and 116 may send the scan data to another remote processor, such as a processor in server 176. The communication between server 176, vehicle 102, and/or location 110 may be via a network/cloud. In one embodiment, a perimeter area outside vehicle 102 may be scanned by the sensors 104 on the vehicle, such as a distance of 4 feet around and external vehicle 102. In another example, the perimeter area external the vehicle 102 may be a location where sensor 104 detects person 106 approaching the vehicle, regardless of how far person 106 is from vehicle 102.
Data pertaining to devices 108/114 may be sent 170/172 to server 176, including at least the location of the devices. Additional data from the devices 108/114 may be included in the sent data 170/172, such as the device model, MEID, MAC, the owner data of the device, and the like. This may occur at intervals, such as every 10 minutes, or when the devices are determined to be proximate to vehicle 102. For example, if the vehicle normally pairs with devices 108 and 114 when at or near a location, such as a residence, then when the devices are at that location, the device data may be sent to server 176. The device data may be sent 174 to the processor 152. This may occur in response to a query to the server from processor 152 (not shown).
FIG. 1C illustrates a message flow diagram 180 according to some example embodiments. Message flow 180 is a continuation of FIG. 1B. The processor 152 analyzes the received sensor data (FIG. 1 B 164/168) to determine the vehicle's occupant 182 identity. The received sensor data may include the time, facial data of the occupant(s) (such as for the comparison of faces in facial recognition), the location of the occupant in the vehicle, etc. Received data may also include people proximate vehicle 102, such as people near vehicle 102 but on the outside of the vehicle. Sensors 104 may be devices on the exterior of vehicle 102, such as cameras. These cameras may detect objects, such as people near vehicle 102. Processor 152 may determine that device 108 and/or person 106 is approaching the vehicle by analysis of the received data 164/168 and/or the received device data 174. For example, the received scan data 164/168 may indicate that the movement of person 106 is getting larger or is approaching vehicle 102. In another example, mmWave Radar is able to detect the movement of the object being scanned, angle of movement, and the like.
In one example, characteristics of people who utilize the vehicle may be stored in memory 154, which may include sensor data (FIG. 1 B 164/168). Over time, the characteristics of a driver and/or occupant(s) may be understood by comparing the stored data with a current driver/occupant. For example, suppose the same person uses vehicle 102 for a number of uses over a threshold. It may be determined that the person is either the main user of vehicle 102 or one of the main users of vehicle 102. In other examples, all regular drivers and/or occupant(s) of vehicle 102 may be determined by analyzing the received sensor data (FIG. 1 B 164/168). Processor 152 may compare the received sensor data (FIG. 1 B 164/168) and the stored previous occupant characteristics to determine the vehicle's occupant 182 identity.
In one example, the analysis involves the utilization of face detection software or similar technologies. The processor 152 may also access data 186 of vehicle occupants of vehicle 102 for comparison and identification that may reside in a memory 154 associated with the processor 152. The data may be stored in a database or other data structure in the memory 154. The processor may query 184 memory 154, wherein a response 188 may contain the result. Response 188 may also include a flag that indicates that the previous occupant is a normal occupant/driver of the vehicle. This flag may be set when the occupant occupies and/or operates vehicle 102, for example, a number of occurrences greater than a threshold.
For example, the processor 152 queries 184 a table of stored previous occupant characteristics 186 in memory 154. This table may be stored in memory 154 or a computer outside the vehicle, such as in server 176, communicably coupled to the vehicle through wireless communication via a network. The table may contain characteristics of people, such as mapping data that the processor 152 may use to compare the received data from the sensors (FIG. 1 B 164/168) on vehicle 102 to the stored characteristics data in the table. In another example, the table may also contain device characteristics (such as a mobile device associated with an occupant of vehicle 102). The device characteristics, which may contain the current location of the device 108/114, may have been received (FIG. 1B 174) by processor 152 from server 176 and stored in memory 154. Knowing the identity 182 of the occupant(s) of vehicle 102 and location 110, and the current location 190 of the devices 108/114, the processor 152 may determine if the device associated with the person in or near vehicle 102 should be device 108 to pair correctly 192. If the device in/proximate to the vehicle is correct, then the system pairs with that device 194.
In one example, the wireless system of vehicle 102 detects another device 114, which may be proximate vehicle 102, at a distance from the vehicle to be within pairing distance of the wireless system in vehicle 102 but not in vehicle 102. This may occur when the vehicle arrives near location 110. In this scenario, the instant solution performs object detection and mapping to determine that while the another device is proximate to the vehicle and within pairing distance of vehicle 102, occupant 112 associated with device 114 is not in vehicle 102, and the wireless system of the vehicle will deny the pairing request.
In a further example, the location of the device may not be enough to determine the occupant of vehicle 102, such as when a person has a device that is not normally associated with that person. Therefore, processor 152 ascertains the identity of the person in or near vehicle 102 before pairing the device in or near vehicle 102 and only pairs with the device in or proximate the vehicle 102 when the identity of the person in or near vehicle 102 is associated with the device in or near the vehicle 102.
In another example, a situation may arise when more than one device is present in vehicle 102, wherein the more than one device has previously been paired with vehicle 102. In this example, processor 152 will pair the device associated with the identified person in the driver's seat of vehicle 102, not the other previously paired device in the vehicle. Received sensor data 164 is analyzed by processor 152 to ascertain the location of occupant 106 in a location in the cabin of vehicle 102, normally used for operating the vehicle. For example, the identity of the occupant is determined by processor 152, who is in the front seat, sitting in the same position as the steering wheel of vehicle 102. In another example, vehicle 102 may be an autonomous or semi-autonomous vehicle. The processor 152 may first pair with the device most recently paired with the vehicle. In another example, the processor 152 may pair with the device that has a higher importance, wherein the importance may be due to the importance of the person associated with the device. For example, if the person is associated with safety (such as emergency personnel). In yet another example, the processor 152 may pair with the device that is associated with the person who may be in the vehicle for a shorter amount of time. For example, two people enter vehicle 102, and one person is determined to go on the full route to the destination, and the other person is determined to be dropped off in 10 minutes. The processor 152 may interwork with a navigation system of vehicle 102 to determine the route of the vehicle, the destination, etc. The procesor 152 may interwork with user data from an external server, for example, where a destination of the person is stored.
In one embodiment, processor 152 automatically disables wireless connectivity (or unpairs the device) if it is determined that occupant 106, associated with the paired device 108, is no longer in vehicle 102. Received sensor data from the sensors 104 in vehicle 102 may send data to processor 152, wherein the processor is able to determine that occupant 106 is no longer in vehicle 102. For example, the occupant ran inside for something that they forgot (coffee, laptop, phone, etc.), is still inside the house and has not gotten into the vehicle, is taking out the trash or moving something out of the way so the vehicle can back out of the garage, etc. Device 108 remains in the vehicle, but the person does not. Therefore processor 152 may disable the pairing of device 108. In one example, processor 152 may send a signal to another processor of the vehicle that causes a tone to be emitted from vehicle 102. This tone may indicate to person 106 that device 108 remains in the vehicle while person 106 has exited vehicle 102.
In another embodiment, if a person (such as occupant 112), who has paired with vehicle 102 in the past, is not currently in vehicle 102 but is on a call with device 114 inside location 110, the vehicle will not pair with that person's associated device 114. However, suppose it is determined that the person has entered the vehicle, such as the analysis of received sensor 104 data. Device 114 will automatically be paired with vehicle 102 (unless vehicle 102 is already paired with another device 108). When processor 152 determines that a paired device is active, even though another person and another device associated with the another person enters vehicle 102, which has previously been paired with vehicle 102, processor 152 will not pair with the another device as a valid device 108 is already paired with the wireless system of the vehicle.
In another example, a person 106 approaching the vehicle 102 may have multiple devices previously paired with the vehicle 102. The processor may choose one of the multiple device to pair with the vehicle 102, based on a priority of the multiple devices. For example, the another device may be a health-related device. If the health-related device has not been paired with vehicle 102, and the processor determines that the driving becomes unsafe (such as due to extreme driving, random steering, hard braking and/or acceleration, etc.), the processor may unpair the device and pair it with the another device. Processor 152 may determine that the driving is unsafe by communicating with other processors in vehicle 102, such as those processors in the steering system, the braking system, the acceleration system, and the like.
In another embodiment, vehicle 102 reserves a connection with a device. When the person is proximate but not in vehicle 102, sensor 104 on the vehicle detects the device's 108 presence before vehicle 102 is started. Sensor 104 may be powered by the battery and is activated, although vehicle 102 has not been started, such as through low power. Sensor 104 may send data to processor 152, where processor 152 performs validation to determine that person 106, associated with device 108, is also proximate to vehicle 102. The sensor may be a camera, for example. Processor 152 reserves device 108 to be paired with vehicle 102 when vehicle 102 is started. Therefore, no other device may be paired with the system when vehicle 102 is started because device 108 is in a reserved state. In one example, when device 108 and/or person 106 associated with device 108 are no longer proximate to vehicle 102, processor 152 removes the reservation. The reserving of the connection for the device may be stored in memory 154 of vehicle 102. This reserved connection may be accessed by the processor 152 upon an event, such as enabling the ignition of vehicle 102.
In one embodiment, multiple wireless connections are possible. For example, one wireless device is paired in the front seats of vehicle 102, and one is paired in the rear seat area of the vehicle. Multiple wireless connections allow multiple streams of media for each wireless connection, such that the sound heard in the front of the cabin of the vehicle comes from the device paired in the front seats, and the sound heard in the rear of the cabin of the vehicle comes from the device paired in the rear seats. The speakers may be modified to allow the separate areas to hear all or most of the sound associated with the respectively paired device, for example, through directional modeling of speaker sounds, moveable speakers, or a modification elements of the sound of the respective speaker, such as the wavelength, amplitude, frequency, period, velocity, loudness, pitch, quality, volume, etc., of the one or more speakers.

FIG. 2E illustrates yet a further transport network diagram 260, according to example embodiments. Referring to FIG. 2E, the network diagram 260 includes a transport 202 connected to other transports 202′ and to an update server node 203 over a blockchain network 206. The transports 202 and 202′ may represent transports/vehicles. The blockchain network 206 may have a ledger 208 for storing software update validation data and a source 207 of the validation for future use (e.g., for an audit).
While this example describes in detail only one transport 202, multiple such nodes may be connected to the blockchain 206. It should be understood that the transport 202 may include additional components and that some of the components described herein may be removed and/or modified without departing from a scope of the instant application. The transport 202 may have a computing device or a server computer, or the like, and may include a processor 204, which may be a semiconductor-based microprocessor, a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), and/or another hardware device. Although a single processor 204 is depicted, it should be understood that the transport 202 may include multiple processors, multiple cores, or the like without departing from the scope of the instant application. The transport 202 could be a transport, server or any device with a processor and memory.

Additionally, one or more steps or features may be added, omitted, combined, performed at a later time, etc.
FIG. 2F illustrates a diagram 265 depicting the electrification of one or more elements. In one example, a transport 266 may provide power stored in its batteries to one or more elements, including other transport(s) 268, charging station(s) 270, and electric grid(s) 272. The electric grid(s) 272 is/are coupled to one or more of the charging stations 270, which may be coupled to one or more of the transports 268. This configuration allows the distribution of electricity/power received from the transport 266. The transport 266 may also interact with the other transport(s) 268, such as via Vehicle to Vehicle (V2V) technology, communication over cellular, WiFi, and the like. The transport 266 may also interact wirelessly and/or wired with other transports 268, the charging station(s) 270 and/or with the electric grid(s) 272. In one example, the transport 266 is routed (or routes itself) in a safe and efficient manner to the electric grid(s) 272, the charging station(s) 270, or the other transport(s) 268. Using one or more embodiments of the instant solution, the transport 266 can provide energy to one or more of the elements depicted herein in various advantageous ways as described and/or depicted herein. Further, the safety and efficiency of the transport may be increased, and the environment may be positively affected as described and/or depicted herein.
The term ‘energy’, ‘electricity’, ‘power’, and the like may be used to denote any form of energy received, stored, used, shared, and/or lost by the vehicles(s). The energy may be referred to in conjunction with a voltage source and/or a current supply of charge provided from an entity to the transport(s) during a charge/use operation. Energy may also be in the form of fossil fuels (for example, for use with a hybrid transport) or via alternative power sources, including but not limited to lithium-based, nickel-based, hydrogen fuel cells, atomic/nuclear energy, fusion-based energy sources, and energy generated on-the-fly during an energy sharing and/or usage operation for increasing or decreasing one or more transports energy levels at a given time.
In one example, the charging station 270 manages the amount of energy transferred from the transport 266 such that there is sufficient charge remaining in the transport 266 to arrive at a destination. In one example, a wireless connection is used to wirelessly direct an amount of energy transfer between transports 268, wherein the transports may both be in motion. In one embodiment, wireless charging may occur via a fixed charger and batteries of the transport in alignment with one another (such as a charging mat in a garage or parking space). In one example, an idle vehicle, such as a vehicle 266 (which may be autonomous) is directed to provide an amount of energy to a charging station 270 and return to the original location (for example, its original location or a different destination). In one example, a mobile energy storage unit (not shown) is used to collect surplus energy from at least one other transport 268 and transfer the stored surplus energy at a charging station 270. In one example, factors determine an amount of energy to transfer to a charging station 270, such as distance, time, as well as traffic conditions, road conditions, environmental/weather conditions, the vehicle's condition (weight, etc.), an occupant(s) schedule while utilizing the vehicle, a prospective occupant(s) schedule waiting for the vehicle, etc. In one example, the transport(s) 268, the charging station(s) 270 and/or the electric grid(s) 272 can provide energy to the transport 266.
In one embodiment, a location such as a building, a residence, or the like (not depicted), communicably coupled to one or more of the electric grid 272, the transport 266, and/or the charging station(s) 270. The rate of electric flow to one or more of the location, the transport 266, the other transport(s) 268 is modified, depending on external conditions, such as weather. For example, when the external temperature is extremely hot or extremely cold, raising the chance for an outage of electricity, the flow of electricity to a connected vehicle 266/268 is slowed to help minimize the chance for an outage.
In one embodiment, transports 266 and 268 may be utilized as bidirectional transports. Bidirectional transports are those that may serve as mobile microgrids that can assist in the supplying of electrical power to the grid 272 and/or reduce the power consumption when the grid is stressed. Bidirectional transports incorporate bidirectional charging, which in addition to receiving a charge to the transport, the transport can take energy from the transport and “push” the energy back into the grid 272, otherwise referred to as “V2G”. In bidirectional charging, the electricity flows both ways; to the transport and from the transport. When a transport is charged, alternating current (AC) electricity from the grid 272 is converted to direct current (DC). This may be performed by one or more of the transport's own converter or a converter on the charger 270. The energy stored in the transport's batteries may be sent in an opposite direction back to the grid. The energy is converted from DC to AC through a converter usually located in the charger 270, otherwise referred to as a bidirectional charger. Further, the instant solution as described and depicted with respect to FIG. 2F can be utilized in this and other networks and/or systems.
FIG. 2G is a diagram showing interconnections between different elements 275. The instant solution may be stored and/or executed entirely or partially on and/or by one or more computing devices 278′, 279′, 281′, 282′, 283′, 284′, 276′, 285′, 287′ and 277′ associated with various entities, all communicably coupled and in communication with a network 286. A database 287 is communicably coupled to the network and allows for the storage and retrieval of data. In one example, the database is an immutable ledger. One or more of the various entities may be a transport 276, one or more service provider 279, one or more public buildings 281, one or more traffic infrastructure 282, one or more residential dwellings 283, an electric grid/charging station 284, a microphone 285, and/or another transport 277. Other entities and/or devices, such as one or more private users using a smartphone 278, a laptop 280, an augmented reality (AR) device, a virtual reality (VR) device, and/or any wearable device may also interwork with the instant solution. The smartphone 278, laptop 280, the microphone 285, and other devices may be connected to one or more of the connected computing devices 278′, 279′, 281′, 282′, 283′, 284′, 276′, 285′, 287′, and 277′. The one or more public buildings 281 may include various agencies. The one or more public buildings 281 may utilize a computing device 281′. The one or more service provider 279 may include a dealership, a tow truck service, a collision center or other repair shop. The one or more service provider 279 may utilize a computing apparatus 279′. These various computer devices may be directly and/or communicably coupled to one another, such as via wired networks, wireless networks, blockchain networks, and the like. The microphone 285 may be utilized as a virtual assistant, in one example. In one example, the one or more traffic infrastructure 282 may include one or more traffic signals, one or more sensors including one or more cameras, vehicle speed sensors or traffic sensors, and/or other traffic infrastructure. The one or more traffic infrastructure 282 may utilize a computing device 282′.
In one embodiment, anytime an electrical charge is given or received to/from a charging station and/or an electrical grid, the entities that allow that to occur are one or more of a vehicle, a charging station, a server, and a network communicably coupled to the vehicle, the charging station, and the electrical grid.
In one example, a transport 277/276 can transport a person, an object, a permanently or temporarily affixed apparatus, and the like. In one example, the transport 277 may communicate with transport 276 via V2V communication through the computers associated with each transport 276′ and 277′ and may be referred to as a transport, car, vehicle, automobile, and the like. The transport 276/277 may be a self-propelled wheeled conveyance, such as a car, a sports utility vehicle, a truck, a bus, a van, or other motor or battery-driven or fuel cell-driven transport. For example, transport 276/277 may be an electric vehicle, a hybrid vehicle, a hydrogen fuel cell vehicle, a plug-in hybrid vehicle, or any other type of vehicle with a fuel cell stack, a motor, and/or a generator. Other examples of vehicles include bicycles, scooters, trains, planes, boats, and any other form of conveyance that is capable of transportation. The transport 276/277 may be semi-autonomous or autonomous. For example, transport 276/277 may be self-maneuvering and navigate without human input. An autonomous vehicle may have and use one or more sensors and/or a navigation unit to drive autonomously.
FIG. 2H is another block diagram showing interconnections between different elements in one example 290. A transport 276 is presented and includes ECUs 295, 296, and a Head Unit (otherwise known as an Infotainment System) 297. An Electrical Control Unit (ECU) is an embedded system in automotive electronics controlling one or more of the electrical systems or subsystems in a transport. ECUs may include but are not limited to the management of a transport's engine, brake system, gearbox system, door locks, dashboard, airbag system, infotainment system, electronic differential, and active suspension. ECUs are connected to the transport's Controller Area Network (CAN) bus 294. The ECUs may also communicate with a transport computer 298 via the CAN bus 294. The transport's processors/sensors (such as the transport computer) 298 can communicate with external elements, such as a server 293 via a network 292 (such as the Internet). Each ECU 295, 296, and Head Unit 297 may contain its own security policy. The security policy defines permissible processes that can be executed in the proper context. In one example, the security policy may be partially or entirely provided in the transport computer 298.
ECUs 295, 296, and Head Unit 297 may each include a custom security functionality element 299 defining authorized processes and contexts within which those processes are permitted to run. Context-based authorization to determine validity if a process can be executed allows ECUs to maintain secure operation and prevent unauthorized access from elements such as the transport's Controller Area Network (CAN Bus). When an ECU encounters a process that is unauthorized, that ECU can block the process from operating. Automotive ECUs can use different contexts to determine whether a process is operating within its permitted bounds, such as proximity contexts such as nearby objects, distance to approaching objects, speed, and trajectory relative to other moving objects, and operational contexts such as an indication of whether the transport is moving or parked, the transport's current speed, the transmission state, user-related contexts such as devices connected to the transport via wireless protocols, use of the infotainment, cruise control, parking assist, driving assist, location-based contexts, and/or other contexts.
Referring to FIG. 2I, an operating environment 290A for a connected transport, is illustrated according to some embodiments. As depicted, the transport 276 includes a Controller Area Network (CAN) bus 291 A connecting elements 292A—299A of the transport. Other elements may be connected to the CAN bus and are not depicted herein. The depicted elements connected to the CAN bus include a sensor set 292A, Electronic Control Units 293A, autonomous features or Advanced Driver Assistance Systems (ADAS) 294A, and the navigation system 295A. In some embodiments, the transport 276 includes a processor 296A, a memory 297A, a communication unit 298A, and an electronic display 299A.
The processor 296A includes an arithmetic logic unit, a microprocessor, a general-purpose controller, and/or a similar processor array to perform computations and provide electronic display signals to a display unit 299A. The processor 296A processes data signals and may include various computing architectures, including a complex instruction set computer (CISC) architecture, a reduced instruction set computer (RISC) architecture, or an architecture implementing a combination of instruction sets. The transport 276 may include one or more processors 296A. Other processors, operating systems, sensors, displays, and physical configurations that are communicably coupled to one another (not depicted) may be used with the instant solution.
Memory 297A is a non-transitory memory storing instructions or data that may be accessed and executed by the processor 296A. The instructions and/or data may include code to perform the techniques described herein. The memory 297A may be a dynamic random-access memory (DRAM) device, a static random-access memory (SRAM) device, flash memory, or another memory device. In some embodiments, the memory 297A also may include non-volatile memory or a similar permanent storage device and media, which may include a hard disk drive, a floppy disk drive, a CD-ROM device, a DVD-ROM device, a DVD-RAM device, a DVD-RW device, a flash memory device, or some other mass storage device for storing information on a permanent basis. A portion of the memory 297A may be reserved for use as a buffer or virtual random-access memory (virtual RAM). The transport 276 may include one or more memories 297A without deviating from the current solution.
The memory 297A of the transport 276 may store one or more of the following types of data: navigation route data 295A, and autonomous features data 294A. In some embodiments, the memory 297A stores data that may be necessary for the navigation application 295A to provide the functions.
The navigation system 295A may describe at least one navigation route including a start point and an endpoint. In some embodiments, the navigation system 295A of the transport 276 receives a request from a user for navigation routes wherein the request includes a starting point and an ending point. The navigation system 295A may query a real-time data server 293 (via a network 292), such as a server that provides driving directions, for navigation route data corresponding to navigation routes, including the start point and the endpoint. The real-time data server 293 transmits the navigation route data to the transport 276 via a wireless network 292, and the communication system 298A stores the navigation data 295A in the memory 297A of the transport 276.
The ECU 293A controls the operation of many of the systems of the transport 276, including the ADAS systems 294A. The ECU 293A may, responsive to instructions received from the navigation system 295A, deactivate any unsafe and/or unselected autonomous features for the duration of a journey controlled by the ADAS systems 294A. In this way, the navigation system 295A may control whether ADAS systems 294A are activated or enabled so that they may be activated for a given navigation route.
The sensor set 292A may include any sensors in the transport 276 generating sensor data. For example, the sensor set 292A may include short-range sensors and long-range sensors. In some embodiments, the sensor set 292A of the transport 276 may include one or more of the following vehicle sensors: a camera, a Lidar sensor, an ultrasonic sensor, an automobile engine sensor, a radar sensor, a laser altimeter, a manifold absolute pressure sensor, an infrared detector, a motion detector, a thermostat, a sound detector, a carbon monoxide sensor, a carbon dioxide sensor, an oxygen sensor, a mass airflow sensor, an engine coolant temperature sensor, a throttle position sensor, a crankshaft position sensor, a valve timer, an air-fuel ratio meter, a blind spot meter, a curb feeler, a defect detector, a Hall effect sensor, a parking sensor, a radar gun, a speedometer, a speed sensor, a tire-pressure monitoring sensor, a torque sensor, a transmission fluid temperature sensor, a turbine speed sensor (TSS), a variable reluctance sensor, a vehicle speed sensor (VSS), a water sensor, a wheel speed sensor, a GPS sensor, a mapping functionality, and any other type of automotive sensor. The navigation system 295A may store the sensor data in the memory 297A.
The communication unit 298A transmits and receives data to and from the network 292 or to another communication channel. In some embodiments, the communication unit 298A may include a DSRC transceiver, a DSRC receiver, and other hardware or software necessary to make the transport 276 a DSRC-equipped device.
The transport 276 may interact with other transports 277 via V2V technology. V2V communication includes sensing radar information corresponding to relative distances to external objects, receiving GPS information of the transports, setting areas as areas where the other transports 277 are located based on the sensed radar information, calculating probabilities that the GPS information of the object vehicles will be located at the set areas, and identifying transports and/or objects corresponding to the radar information and the GPS information of the object vehicles based on the calculated probabilities, in one example.
For a transport to be adequately secured, the transport must be protected from unauthorized physical access as well as unauthorized remote access (e.g., cyber-threats). To prevent unauthorized physical access, a transport is equipped with a secure access system such as a keyless entry in one example. Meanwhile, security protocols are added to a transport's computers and computer networks to facilitate secure remote communications to and from the transport in one example.
Electronic Control Units (ECUs) are nodes within a transport that control tasks such as activating the windshield wipers to tasks such as an anti-lock brake system. ECUs are often connected to one another through the transport's central network, which may be referred to as a controller area network (CAN). State-of-the-art features such as autonomous driving are strongly reliant on implementing new, complex ECUs such as advanced driver-assistance systems (ADAS), sensors, and the like. While these new technologies have helped improve the safety and driving experience of a transport, they have also increased the number of externally-communicating units inside of the transport, making them more vulnerable to attack. Below are some examples of protecting the transport from physical intrusion and remote intrusion.
FIG. 2J illustrates a keyless entry system 290B to prevent unauthorized physical access to a transport 291B, according to example embodiments. Referring to FIG. 2J, a key fob 292B transmits commands to a transport 291B using radio frequency signals in one example. In this example, the key fob 292B includes a transmitter 2921B with an antenna that is capable of sending short-range wireless radio signals. The transport 291B includes a receiver 2911B with an antenna that is capable of receiving the short-range wireless signal transmitted from the transmitter 2921B. The key fob 292B and the transport 291B also include CPUs 2922B and 2913B, respectively, which control the respective devices. Here, a memory of the CPUs 2922B and 2913B (or accessible to the CPUs). Each of the key fob 292B and the transport 291B includes power supplies 2924B and 2915B for powering the respective devices in one example.
When the user presses a button 293B (or otherwise actuates the fob, etc.) on the key fob 292B, the CPU 2922B wakes up inside the key fob 292B and sends a data stream to the transmitter 2921B, which is output via the antenna. In other embodiments, the user's intent is acknowledged on the key fob 292B via other means, such as via a microphone that accepts audio, a camera that captures images and/or video, or other sensors that are commonly utilized in the art to detect intent from a user including receiving gestures, motion, eye movements, and the like. The data stream may be a 64-bit to 128-bit long signal, which includes one or more of a preamble, a command code, and a rolling code. The signal may be sent at a rate between 2 KHz and 20 KHz, but embodiments are not limited thereto. In response, the receiver 2911B of the transport 291B captures the signal from the transmitter 2921B, demodulates the signal, and sends the data stream to the CPU 2913B, which decodes the signal and sends commands (e.g., lock the door, unlock the door, etc.) to a command module 2912B.
If the key fob 292B and the transport 291B use a fixed code between them, replay attacks can be performed. In this case, if the attacker can capture/sniff the fixed code during the short-range communication, the attacker could replay this code to gain entry into the transport 291B. To improve security, the key fob and the transport 291B may use a rolling code that changes after each use. Here, the key fob 292B and the transport 291B are synchronized with an initial seed 2923B (e.g., a random number, pseudo-random number, etc.) This is referred to as pairing. The key fob 292B and the transport 291B also include a shared algorithm for modifying the initial seed 2914B each time the button 293B is pressed. The following keypress will take the result of the previous keypress as an input and transform it into the next number in the sequence. In some cases, the transport 291B may store multiple next codes (e.g., 255 next codes) in case the keypress on the key fob 292B is not detected by the transport 291B. Thus, a number of keypress on the key fob 292B that are unheard by the transport 291B do not prevent the transport from becoming out of sync.
In addition to rolling codes, the key fob 292B and the transport 291B may employ other methods to make attacks even more difficult. For example, different frequencies may be used for transmitting the rolling codes. As another example, two-way communication between the transmitter 2921B and the receiver 2911B may be used to establish a secure session. As another example, codes may have limited expirations or timeouts. Further, the instant solution as described and depicted with respect to FIG. 2J can be utilized in this and other networks and/or systems, including those that are described and depicted herein.
FIG. 2K illustrates a controller area network (CAN) 290C within a transport, according to example embodiments. Referring to FIG. 2K, the CAN 290C includes a CAN bus 297C with a high and low terminal and a plurality of electronic control units (ECUs) 291C, 292C, 293C, etc. which are connected to the CAN bus 297C via wired connections. The CAN bus 297C is designed to allow microcontrollers and devices to communicate with each other in an application without a host computer. The CAN bus 297C implements a message-based protocol (i.e., ISO 11898 standards) that allows ECUs 291C-293C to send commands to one another at a root level. Meanwhile, the ECUs 291C-293C represent controllers for controlling electrical systems or subsystems within the transport. Examples of the electrical systems include power steering, anti-lock brakes, air-conditioning, tire pressure monitoring, cruise control, and many other features.
In this example, the ECU 291C includes a transceiver 2911C and a microcontroller 2912C. The transceiver may be used to transmit and receive messages to and from the CAN bus 297C. For example, the transceiver 2911C may convert the data from the microcontroller 2912C into a format of the CAN bus 297C and also convert data from the CAN bus 297C into a format for the microcontroller 2912C. Meanwhile, the microcontroller 2912C interprets the messages and also decide what messages to send using ECU software installed therein in one example.
To protect the CAN 290C from cyber threats, various security protocols may be implemented. For example, sub-networks (e.g., sub-networks A and B, etc.) may be used to divide the CAN 290C into smaller sub-CANs and limit an attacker's capabilities to access the transport remotely. In the example of FIG. 2K, ECUs 291C and 292C may be part of a same sub-network, while ECU 293C is part of an independent sub-network. Furthermore, a firewall 294C (or gateway, etc.) may be added to block messages from crossing the CAN bus 297C across sub-networks. If an attacker gains access to one sub-network, the attacker will not have access to the entire network. To make sub-networks even more secure, the most critical ECUs are not placed on the same sub-network, in one example.
Although not shown in FIG. 2K, other examples of security controls within a CAN include an intrusion detection system (IDS) which can be added to each sub-network and read all data passing to detect malicious messages. If a malicious message is detected, the IDS can notify the automobile user. Other possible security protocols include encryption/security keys that can be used to obscure messages. As another example, authentication protocols are implemented that enables a message to authenticate itself, in one example.
In addition to protecting a transport's internal network, transports may also be protected when communicating with external networks such as the Internet. One of the benefits of having a transport connection to a data source such as the Internet is that information from the transport can be sent through a network to remote locations for analysis. Examples of transport information include GPS, onboard diagnostics, tire pressure, and the like. These communication systems are often referred to as telematics because they involve the combination of telecommunications and informatics. Further, the instant solution as described and depicted with respect to FIG. 2K can be utilized in this and other networks and/or systems, including those that are described and depicted herein.
FIG. 2L illustrates a secure end-to-end transport communication channel according to example embodiments. Referring to FIG. 2L, a telematics network 290D includes a transport 291D and a host server 295D that is disposed at a remote location (e.g., a web server, a cloud platform, a database, etc.) and connected to the transport 291D via a network such as the Internet. In this example, a device 296D associated with the host server 295D may be installed within the network inside the transport 291D. Furthermore, although not shown, the device 296D may connect to other elements of the transport 291D, such as the CAN bus, an onboard diagnostics (ODBII) port, a GPS system, a SIM card, a modem, and the like. The device 296D may collect data from any of these systems and transfer the data to the server 295D via the network.
Secure management of data begins with the transport 291D. In some embodiments, the device 296D may collect information before, during, and after a trip. The data may include GPS data, travel data, passenger information, diagnostic data, fuel data, speed data, and the like. However, the device 296D may only communicate the collected information back to the host server 295D in response to transport ignition and trip completion. Furthermore, communication may only be initiated by the device 296D and not by the host server 295D. As such, the device 296D will not accept communications initiated by outside sources in one example.
To perform the communication, the device 296D may establish a secured private network between the device 296D and the host server 295D. Here, the device 296D may include a tamper-proof SIM card that provides secure access to a carrier network 294D via a radio tower 292D. When preparing to transmit data to the host server 295D, the device 296D may establish a one-way secure connection with the host server 295D. The carrier network 294D may communicate with the host server 295D using one or more security protocols. As a non-limiting example, the carrier network 294D may communicate with the host server 295D via a VPN tunnel which allows access through a firewall 293D of the host server 295D. As another example, the carrier network 294D may use data encryption (e.g., AES encryption, etc.) when transmitting data to the host server 295D. In some cases, the system may use multiple security measures such as both a VPN and encryption to further secure the data.
In addition to communicating with external servers, transports may also communicate with each other. In particular, transport-to-transport (V2V) communication systems enable transports to communicate with each other, roadside infrastructures (e.g., traffic lights, signs, cameras, parking meters, etc.), and the like, over a wireless network. The wireless network may include one or more of Wi-Fi networks, cellular networks, dedicated short-range communication (DSRC) networks, and the like. Transports may use V2V communication to provide other transports with information about a transport's speed, acceleration, braking, and direction, to name a few. Accordingly, transports can receive insight into the conditions ahead before such conditions become visible, thus greatly reducing collisions. Further, the instant solution as described and depicted with respect to FIG. 2L can be utilized in this and other networks and/or systems, including those that are described and depicted herein.
FIG. 2M illustrates an example 290E of transports 293E and 292E performing secured V2V communications using security certificates, according to example embodiments. Referring to FIG. 2M, the transports 293E and 292E may communicate via V2V communications over a short-range network, a cellular network, or the like. Before sending messages, the transports 293E and 292E may sign the messages using a respective public key certificate. For example, the transport 293E may sign a V2V message using a public key certificate 294E. Likewise, the transport 292E may sign a V2V message using a public key certificate 295E. The public key certificates 294E and 295E are associated with the transports 293E and 292E, respectively, in one example.
Upon receiving the communications from each other, the transports may verify the signatures with a certificate authority 291E or the like. For example, the transport 292E may verify with the certificate authority 291E that the public key certificate 294E used by transport 293E to sign a V2V communication is authentic. If the transport 292E successfully verifies the public key certificate 294E, the transport knows that the data is from a legitimate source. Likewise, the transport 293E may verify with the certificate authority 291E that the public key certificate 295E used by the transport 292E to sign a V2V communication is authentic. Further, the instant solution as described and depicted with respect to FIG. 2M can be utilized in this and other networks and/or systems including those that are described and depicted herein.
FIG. 2N illustrates yet a further diagram 290F depicting an example of a transport interacting with a security processor and a wireless device, according to example embodiments. In some embodiments, the computer 224 shown in FIG. 2B may include security processor 292F as shown in the process 290F of the example of FIG. 2N. In particular, the security processor 292F may perform authorization, authentication, cryptography (e.g., encryption), and the like, for data transmissions that are sent between ECUs and other devices on a CAN bus of a vehicle, and also data messages that are transmitted between different vehicles.
In the example of FIG. 2N, the security processor 292F may include an authorization module 293F, an authentication module 294F, and a cryptography module 295F. The security processor 292F may be implemented within the transport's computer and may communicate with other transport elements, for example, the ECUs/CAN network 296F, wired and wireless devices 298F such as wireless network interfaces, input ports, and the like. The security processor 292F may ensure that data frames (e.g., CAN frames, etc.) that are transmitted internally within a transport (e.g., via the ECUs/CAN network 296F) are secure. Likewise, the security processor 292F can ensure that messages transmitted between different transports and devices attached or connected via a wire to the transport's computer are also secured.
For example, the authorization module 293F may store passwords, usernames, PIN codes, biometric scans, and the like for different transport users. The authorization module 293F may determine whether a user (or technician) has permission to access certain settings such as a transport's computer. In some embodiments, the authorization module may communicate with a network interface to download any necessary authorization information from an external server. When a user desires to make changes to the transport settings or modify technical details of the transport via a console or GUI within the transport or via an attached/connected device, the authorization module 293F may require the user to verify themselves in some way before such settings are changed. For example, the authorization module 293F may require a username, a password, a PIN code, a biometric scan, a predefined line drawing or gesture, and the like. In response, the authorization module 293F may determine whether the user has the necessary permissions (access, etc.) being requested.
The authentication module 294F may be used to authenticate internal communications between ECUs on the CAN network of the vehicle. As an example, the authentication module 294F may provide information for authenticating communications between the ECUS. As an example, the authentication module 294F may transmit a bit signature algorithm to the ECUs of the CAN network. The ECUs may use the bit signature algorithm to insert authentication bits into the CAN fields of the CAN frame. All ECUs on the CAN network typically receive each CAN frame. The bit signature algorithm may dynamically change the position, amount, etc., of authentication bits each time a new CAN frame is generated by one of the ECUs. The authentication module 294F may also provide a list of ECUs that are exempt (safe list) and that do not need to use the authentication bits. The authentication module 294F may communicate with a remote server to retrieve updates to the bit signature algorithm and the like.
The encryption module 295F may store asymmetric key pairs to be used by the transport to communicate with other external user devices and transports. For example, the encryption module 295F may provide a private key to be used by the transport to encrypt/decrypt communications, while the corresponding public key may be provided to other user devices and transports to enable the other devices to decrypt/encrypt the communications. The encryption module 295F may communicate with a remote server to receive new keys, updates to keys, keys of new transports, users, etc., and the like. The encryption module 295F may also transmit any updates to a local private/public key pair to the remote server.
FIG. 3A illustrates a flow diagram 300, according to example embodiments. Referring to FIG. 3A, the solution includes one or more of determining that a device associated with a vehicle approaches the vehicle or in the vehicle 302, determines that a person associated with the device approaches the vehicle or in the vehicle 304, and pairs the device with the vehicle 306.
FIG. 3B illustrates another flow diagram 320, according to example embodiments. Referring to FIG. 3B, the solution includes one or more of analyzing received data from sensors on the vehicle, wherein the received data comprises an area inside the vehicle and an external perimeter area of the vehicle, in the determining that the person is approaching the vehicle or is in the vehicle 322, determining that another device is not proximate the vehicle, but is at a pairing distance with the vehicle, determining that the another person associated with the another device is not in the vehicle, and not pairing the another device and the vehicle 323, determining that more than one device associated with the vehicle is approaching the vehicle or is in the vehicle, and pairing with a device of the more than one device associated with a person closer to a driver's seat of the vehicle 324, determining that the person associated with the device is no longer in the or proximate the vehicle, determining that the device associated with the person remains in the vehicle, and unpairing the device 325, determining, by sensors on the vehicle, that the person is approaching the vehicle, and reserving the device for the paring 326, and determining that another device associated with the vehicle is approaching the vehicle or is in the vehicle, determining that the another device is associated with the person, determining a higher priority between the device and the another device, and pairing with one of the device and the another device, based on the higher priority 327.
FIG. 3C illustrates yet another flow diagram 340, according to example embodiments. Referring to FIG. 3C, the flow diagram includes one or more of receiving a confirmation of an event from one or more elements described or depicted herein, wherein the confirmation comprises a blockchain consensus between peers represented by any of the elements 342 and executing a smart contract to record the confirmation on a blockchain-based on the blockchain consensus 344.
FIG. 4 illustrates a machine learning transport network diagram 400, according to example embodiments. The network 400 includes a transport 402 that interfaces with a machine learning subsystem 406. The transport includes one or more sensors 404.
The machine learning subsystem 406 contains a learning model 408, which is an artifact created by a machine learning training system 410 that generates predictions by finding patterns in one or more training data sets. In some embodiments, the machine learning subsystem 406 resides in the transport node 402. An artifact is used to describe an output created by a training process, such as a checkpoint, a file, or a model. In other embodiments, the machine learning subsystem 406 resides outside of the transport node 402.
The transport 402 sends data from the one or more sensors 404 to the machine learning subsystem 406. The machine learning subsystem 406 provides the one or more sensor 404 data to the learning model 408, which returns one or more predictions. The machine learning subsystem 406 sends one or more instructions to the transport 402 based on the predictions from the learning model 408.
In a further embodiment, the transport 402 may send the one or more sensor 404 data to the machine learning training system 410. In yet another example, the machine learning subsystem 406 may send the sensor 404 data to the machine learning subsystem 410. One or more of the applications, features, steps, solutions, etc., described and/or depicted herein may utilize the machine learning network 400 as described herein.
FIG. 5A illustrates an example vehicle configuration 500 for managing database transactions associated with a vehicle, according to example embodiments. Referring to FIG. 5A, as a particular transport/vehicle 525 is engaged in transactions (e.g., vehicle service, dealer transactions, delivery/pickup, transportation services, etc.), the vehicle may receive assets 510 and/or expel/transfer assets 512 according to a transaction(s). A transport processor 526 resides in the vehicle 525 and communication exists between the transport processor 526, a database 530, a transport processor 526 and the transaction module 520. The transaction module 520 may record information, such as assets, parties, credits, service descriptions, date, time, location, results, notifications, unexpected events, etc. Those transactions in the transaction module 520 may be replicated into a database 530. The database 530 can be one of a SQL database, an RDBMS, a relational database, a non-relational database, a blockchain, a distributed ledger, and may be on board the transport, may be off-board the transport, may be accessed directly and/or through a network, or be accessible to the transport.
FIG. 5B illustrates an example vehicle configuration 550 for managing database transactions conducted among various vehicles, according to example embodiments. The vehicle 525 may engage with another vehicle 508 to perform various actions such as to share, transfer, acquire service calls, etc. when the vehicle has reached a status where the services need to be shared with another vehicle. For example, the vehicle 508 may be due for a battery charge and/or may have an issue with a tire and may be in route to pick up a package for delivery. A transport processor 528 resides in the vehicle 508 and communication exists between the transport processor 528, a database 554, and the transaction module 552. The vehicle 508 may notify another vehicle 525, which is in its network and which operates on its blockchain member service. A transport processor 526 resides in the vehicle 525 and communication exists between the transport processor 526, a database 530, the transport processor 526 and a transaction module 520. The vehicle 525 may then receive the information via a wireless communication request to perform the package pickup from the vehicle 508 and/or from a server (not shown). The transactions are logged in the transaction modules 552 and 520 of both vehicles. The credits are transferred from vehicle 508 to vehicle 525 and the record of the transferred service is logged in the database 530/554 assuming that the blockchains are different from one another, or are logged in the same blockchain used by all members. The database 554 can be one of a SQL database, an RDBMS, a relational database, a non-relational database, a blockchain, a distributed ledger, and may be on board the transport, may be off-board the transport, may be accessible directly and/or through a network.
FIG. 6A illustrates a blockchain architecture configuration 600, according to example embodiments. Referring to FIG. 6A, the blockchain architecture 600 may include certain blockchain elements, for example, a group of blockchain member nodes 602-606 as part of a blockchain group 610. In one example embodiment, a permissioned blockchain is not accessible to all parties but only to those members with permissioned access to the blockchain data. The blockchain nodes participate in a number of activities, such as blockchain entry addition and validation process (consensus). One or more of the blockchain nodes may endorse entries based on an endorsement policy and may provide an ordering service for all blockchain nodes. A blockchain node may initiate a blockchain action (such as an authentication) and seek to write to a blockchain immutable ledger stored in the blockchain, a copy of which may also be stored on the underpinning physical infrastructure.
The blockchain transactions 620 are stored in memory of computers as the transactions are received and approved by the consensus model dictated by the members' nodes. Approved transactions 626 are stored in current blocks of the blockchain and committed to the blockchain via a committal procedure, which includes performing a hash of the data contents of the transactions in a current block and referencing a previous hash of a previous block. Within the blockchain, one or more smart contracts 630 may exist that define the terms of transaction agreements and actions included in smart contract executable application code 632, such as registered recipients, vehicle features, requirements, permissions, sensor thresholds, etc. The code may be configured to identify whether requesting entities are registered to receive vehicle services, what service features they are entitled/required to receive given their profile statuses and whether to monitor their actions in subsequent events. For example, when a service event occurs and a user is riding in the vehicle, the sensor data monitoring may be triggered, and a certain parameter, such as a vehicle charge level, may be identified as being above/below a particular threshold for a particular period of time, then the result may be a change to a current status, which requires an alert to be sent to the managing party (i.e., vehicle owner, vehicle operator, server, etc.) so the service can be identified and stored for reference. The vehicle sensor data collected may be based on types of sensor data used to collect information about vehicle's status. The sensor data may also be the basis for the vehicle event data 634, such as a location(s) to be traveled, an average speed, a top speed, acceleration rates, whether there were any collisions, was the expected route taken, what is the next destination, whether safety measures are in place, whether the vehicle has enough charge/fuel, etc. All such information may be the basis of smart contract terms 630, which are then stored in a blockchain. For example, sensor thresholds stored in the smart contract can be used as the basis for whether a detected service is necessary and when and where the service should be performed.
FIG. 6B illustrates a shared ledger configuration, according to example embodiments. Referring to FIG. 6B, the blockchain logic example 640 includes a blockchain application interface 642 as an API or plug-in application that links to the computing device and execution platform for a particular transaction. The blockchain configuration 640 may include one or more applications, which are linked to application programming interfaces (APIs) to access and execute stored program/application code (e.g., smart contract executable code, smart contracts, etc.), which can be created according to a customized configuration sought by participants and can maintain their own state, control their own assets, and receive external information. This can be deployed as an entry and installed, via appending to the distributed ledger, on all blockchain nodes.
The smart contract application code 644 provides a basis for the blockchain transactions by establishing application code, which when executed causes the transaction terms and conditions to become active. The smart contract 630, when executed, causes certain approved transactions 626 to be generated, which are then forwarded to the blockchain platform 652. The platform includes a security/authorization 658, computing devices, which execute the transaction management 656 and a storage portion 654 as a memory that stores transactions and smart contracts in the blockchain.
The blockchain platform may include various layers of blockchain data, services (e.g., cryptographic trust services, virtual execution environment, etc.), and underpinning physical computer infrastructure that may be used to receive and store new entries and provide access to auditors, which are seeking to access data entries. The blockchain may expose an interface that provides access to the virtual execution environment necessary to process the program code and engage the physical infrastructure. Cryptographic trust services may be used to verify entries such as asset exchange entries and keep information private.
The blockchain architecture configuration of FIGS. 6A and 6B may process and execute program/application code via one or more interfaces exposed, and services provided, by the blockchain platform. As a non-limiting example, smart contracts may be created to execute reminders, updates, and/or other notifications subject to the changes, updates, etc. The smart contracts can themselves be used to identify rules associated with authorization and access requirements and usage of the ledger. For example, the information may include a new entry, which may be processed by one or more processing entities (e.g., processors, virtual machines, etc.) included in the blockchain layer. The result may include a decision to reject or approve the new entry based on the criteria defined in the smart contract and/or a consensus of the peers. The physical infrastructure may be utilized to retrieve any of the data or information described herein.
Within smart contract executable code, a smart contract may be created via a high-level application and programming language, and then written to a block in the blockchain. The smart contract may include executable code that is registered, stored, and/or replicated with a blockchain (e.g., distributed network of blockchain peers). An entry is an execution of the smart contract code, which can be performed in response to conditions associated with the smart contract being satisfied. The executing of the smart contract may trigger a trusted modification(s) to a state of a digital blockchain ledger. The modification(s) to the blockchain ledger caused by the smart contract execution may be automatically replicated throughout the distributed network of blockchain peers through one or more consensus protocols.
The smart contract may write data to the blockchain in the format of key-value pairs. Furthermore, the smart contract code can read the values stored in a blockchain and use them in application operations. The smart contract code can write the output of various logic operations into the blockchain. The code may be used to create a temporary data structure in a virtual machine or other computing platform. Data written to the blockchain can be public and/or can be encrypted and maintained as private. The temporary data that is used/generated by the smart contract is held in memory by the supplied execution environment, then deleted once the data needed for the blockchain is identified.
A smart contract executable code may include the code interpretation of a smart contract, with additional features. As described herein, the smart contract executable code may be program code deployed on a computing network, where it is executed and validated by chain validators together during a consensus process. The smart contract executable code receives a hash and retrieves from the blockchain a hash associated with the data template created by use of a previously stored feature extractor. If the hashes of the hash identifier and the hash created from the stored identifier template data match, then the smart contract executable code sends an authorization key to the requested service. The smart contract executable code may write to the blockchain data associated with the cryptographic details.
FIG. 6C illustrates a blockchain configuration for storing blockchain transaction data, according to example embodiments. Referring to FIG. 6C, the example configuration 660 provides for the vehicle 662, the user device 664 and a server 666 sharing information with a distributed ledger (i.e., blockchain) 668. The server may represent a service provider entity inquiring with a vehicle service provider to share user profile rating information in the event that a known and established user profile is attempting to rent a vehicle with an established rated profile. The server 666 may be receiving and processing data related to a vehicle's service requirements. As the service events occur, such as the vehicle sensor data indicates a need for fuel/charge, a maintenance service, etc., a smart contract may be used to invoke rules, thresholds, sensor information gathering, etc., which may be used to invoke the vehicle service event. The blockchain transaction data 670 is saved for each transaction, such as the access event, the subsequent updates to a vehicle's service status, event updates, etc. The transactions may include the parties, the requirements (e.g., 18 years of age, service eligible candidate, valid driver's license, etc.), compensation levels, the distance traveled during the event, the registered recipients permitted to access the event and host a vehicle service, rights/permissions, sensor data retrieved during the vehicle event operation to log details of the next service event and identify a vehicle's condition status, and thresholds used to make determinations about whether the service event was completed and whether the vehicle's condition status has changed.
FIG. 6D illustrates blockchain blocks 680 that can be added to a distributed ledger, according to example embodiments, and contents of block structures 682A to 682 n. Referring to FIG. 6D, clients (not shown) may submit entries to blockchain nodes to enact activity on the blockchain. As an example, clients may be applications that act on behalf of a requester, such as a device, person or entity to propose entries for the blockchain. The plurality of blockchain peers (e.g., blockchain nodes) may maintain a state of the blockchain network and a copy of the distributed ledger. Different types of blockchain nodes/peers may be present in the blockchain network including endorsing peers, which simulate and endorse entries proposed by clients and committing peers which verify endorsements, validate entries, and commit entries to the distributed ledger. In this example, the blockchain nodes may perform the role of endorser node, committer node, or both.
The instant system includes a blockchain that stores immutable, sequenced records in blocks, and a state database (current world state) maintaining a current state of the blockchain. One distributed ledger may exist per channel and each peer maintains its own copy of the distributed ledger for each channel of which they are a member. The instant blockchain is an entry log, structured as hash-linked blocks where each block contains a sequence of N entries. Blocks may include various components such as those shown in FIG. 6D. The linking of the blocks may be generated by adding a hash of a prior block's header within a block header of a current block. In this way, all entries on the blockchain are sequenced and cryptographically linked together preventing tampering with blockchain data without breaking the hash links. Furthermore, because of the links, the latest block in the blockchain represents every entry that has come before it. The instant blockchain may be stored on a peer file system (local or attached storage), which supports an append-only blockchain workload.
The current state of the blockchain and the distributed ledger may be stored in the state database. Here, the current state data represents the latest values for all keys ever included in the chain entry log of the blockchain. Smart contract executable code invocations execute entries against the current state in the state database. To make these smart contract executable code interactions extremely efficient, the latest values of all keys are stored in the state database. The state database may include an indexed view into the entry log of the blockchain, it can therefore be regenerated from the chain at any time. The state database may automatically get recovered (or generated if needed) upon peer startup, before entries are accepted.
Endorsing nodes receive entries from clients and endorse the entry based on simulated results. Endorsing nodes hold smart contracts, which simulate the entry proposals. When an endorsing node endorses an entry, the endorsing nodes creates an entry endorsement, which is a signed response from the endorsing node to the client application indicating the endorsement of the simulated entry. The method of endorsing an entry depends on an endorsement policy that may be specified within smart contract executable code. An example of an endorsement policy is “the majority of endorsing peers must endorse the entry.” Different channels may have different endorsement policies. Endorsed entries are forward by the client application to an ordering service.
The ordering service accepts endorsed entries, orders them into a block, and delivers the blocks to the committing peers. For example, the ordering service may initiate a new block when a threshold of entries has been reached, a timer times out, or another condition. In this example, blockchain node is a committing peer that has received a data block 682A for storage on the blockchain. The ordering service may be made up of a cluster of orderers. The ordering service does not process entries, smart contracts, or maintain the shared ledger. Rather, the ordering service may accept the endorsed entries and specifies the order in which those entries are committed to the distributed ledger. The architecture of the blockchain network may be designed such that the specific implementation of ‘ordering’ (e.g., Solo, Kafka, BFT, etc.) becomes a pluggable component.
Entries are written to the distributed ledger in a consistent order. The order of entries is established to ensure that the updates to the state database are valid when they are committed to the network. Unlike a cryptocurrency blockchain system (e.g., Bitcoin, etc.) where ordering occurs through the solving of a cryptographic puzzle, or mining, in this example the parties of the distributed ledger may choose the ordering mechanism that best suits that network.
Referring to FIG. 6D, a block 682A (also referred to as a data block) that is stored on the blockchain and/or the distributed ledger may include multiple data segments such as a block header 684A to 684 n, transaction-specific data 686A to 686 n, and block metadata 688A to 688 n. It should be appreciated that the various depicted blocks and their contents, such as block 682A and its contents are merely for purposes of an example and are not meant to limit the scope of the example embodiments. In some cases, both the block header 684A and the block metadata 688A may be smaller than the transaction-specific data 686A, which stores entry data; however, this is not a requirement. The block 682A may store transactional information of N entries (e.g., 100, 500, 1000, 2000, 3000, etc.) within the block data 690A to 690 n. The block 682A may also include a link to a previous block (e.g., on the blockchain) within the block header 684A. In particular, the block header 684A may include a hash of a previous block's header. The block header 684A may also include a unique block number, a hash of the block data 690A of the current block 682A, and the like. The block number of the block 682A may be unique and assigned in an incremental/sequential order starting from zero. The first block in the blockchain may be referred to as a genesis block, which includes information about the blockchain, its members, the data stored therein, etc.
The block data 690A may store entry information of each entry that is recorded within the block. For example, the entry data may include one or more of a type of the entry, a version, a timestamp, a channel ID of the distributed ledger, an entry ID, an epoch, a payload visibility, a smart contract executable code path (deploy tx), a smart contract executable code name, a smart contract executable code version, input (smart contract executable code and functions), a client (creator) identify such as a public key and certificate, a signature of the client, identities of endorsers, endorser signatures, a proposal hash, smart contract executable code events, response status, namespace, a read set (list of key and version read by the entry, etc.), a write set (list of key and value, etc.), a start key, an end key, a list of keys, a Merkel tree query summary, and the like. The entry data may be stored for each of the N entries.
In some embodiments, the block data 690A may also store transaction-specific data 686A, which adds additional information to the hash-linked chain of blocks in the blockchain. Accordingly, the data 686A can be stored in an immutable log of blocks on the distributed ledger. Some of the benefits of storing such data 686A are reflected in the various embodiments disclosed and depicted herein. The block metadata 688A may store multiple fields of metadata (e.g., as a byte array, etc.). Metadata fields may include signature on block creation, a reference to a last configuration block, an entry filter identifying valid and invalid entries within the block, last offset persisted of an ordering service that ordered the block, and the like. The signature, the last configuration block, and the orderer metadata may be added by the ordering service. Meanwhile, a committer of the block (such as a blockchain node) may add validity/invalidity information based on an endorsement policy, verification of read/write sets, and the like. The entry filter may include a byte array of a size equal to the number of entries in the block data 610A and a validation code identifying whether an entry was valid/invalid.
The other blocks 682B to 682 n in the blockchain also have headers, files, and values. However, unlike the first block 682A, each of the headers 684A to 684 n in the other blocks includes the hash value of an immediately preceding block. The hash value of the immediately preceding block may be just the hash of the header of the previous block or may be the hash value of the entire previous block. By including the hash value of a preceding block in each of the remaining blocks, a trace can be performed from the Nth block back to the genesis block (and the associated original file) on a block-by-block basis, as indicated by arrows 692, to establish an auditable and immutable chain-of-custody.
The above embodiments may be implemented in hardware, in a computer program executed by a processor, in firmware, or in a combination of the above. A computer program may be embodied on a computer readable medium, such as a storage medium. For example, a computer program may reside in random access memory (“RAM”), flash memory, read-only memory (“ROM”), erasable programmable read-only memory (“EPROM”), electrically erasable programmable read-only memory (“EEPROM”), registers, hard disk, a removable disk, a compact disk read-only memory (“CD-ROM”), or any other form of storage medium known in the art.
An exemplary storage medium may be coupled to the processor such that the processor may read information from, and write information to, the storage medium. In the alternative, the storage medium may be integral to the processor. The processor and the storage medium may reside in an application-specific integrated circuit (“ASIC”). In the alternative, the processor and the storage medium may reside as discrete components. For example, FIG. 7 illustrates an example computer system architecture 700, which may represent or be integrated in any of the above-described components, etc.
FIG. 7 is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the application described herein. Regardless, the computing node 700 is capable of being implemented and/or performing any of the functionality set forth hereinabove.
In computing node 700 there is a computer system/server 702, which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server 702 include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like.
Computer system/server 702 may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server 702 may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.
As shown in FIG. 7 , computer system/server 702 in cloud computing node 700 is shown in the form of a general-purpose computing device. The components of computer system/server 702 may include, but are not limited to, one or more processors or processing units 704, a system memory 706, and a bus that couples various system components including system memory 706 to processor 704.

Computer system/server 702 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server 702, and it includes both volatile and non-volatile media, removable and non-removable media. System memory 706, in one example, implements the flow diagrams of the other figures. The system memory 706 can include computer system readable media in the form of volatile memory, such as random-access memory (RAM) 708 and/or cache memory 710. Computer system/server 702 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, memory 706 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to the bus by one or more data media interfaces. As will be further depicted and described below, memory 706 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of various embodiments of the application.
Program/utility, having a set (at least one) of program modules, may be stored in memory 706 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules generally carry out the functions and/or methodologies of various embodiments of the application as described herein.
As will be appreciated by one skilled in the art, aspects of the present application may be embodied as a system, method, or computer program product. Accordingly, aspects of the present application may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects of the present application may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.
Computer system/server 702 may also communicate with one or more external devices via an I/O device 712 (such as an I/O adapter), which may include a keyboard, a pointing device, a display, a voice recognition module, etc., one or more devices that enable a user to interact with computer system/server 702, and/or any devices (e.g., network card, modem, etc.) that enable computer system/server 702 to communicate with one or more other computing devices. Such communication can occur via I/O interfaces of the device 712. Still yet, computer system/server 702 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via a network adapter. As depicted, device 712 communicates with the other components of computer system/server 702 via a bus. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server 702. Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.
Although an exemplary embodiment of at least one of a system, method, and non-transitory computer readable medium has been illustrated in the accompanied drawings and described in the foregoing detailed description, it will be understood that the application is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications, and substitutions as set forth and defined by the following claims. For example, the capabilities of the system of the various figures can be performed by one or more of the modules or components described herein or in a distributed architecture and may include a transmitter, receiver or pair of both. For example, all or part of the functionality performed by the individual modules, may be performed by one or more of these modules. Further, the functionality described herein may be performed at various times and in relation to various events, internal or external to the modules or components. Also, the information sent between various modules can be sent between the modules via at least one of: a data network, the Internet, a voice network, an Internet Protocol network, a wireless device, a wired device and/or via plurality of protocols. Also, the messages sent or received by any of the modules may be sent or received directly and/or via one or more of the other modules.
One skilled in the art will appreciate that a “system” could be embodied as a personal computer, a server, a console, a personal digital assistant (PDA), a cell phone, a tablet computing device, a smartphone or any other suitable computing device, or combination of devices. Presenting the above-described functions as being performed by a “system” is not intended to limit the scope of the present application in any way but is intended to provide one example of many embodiments. Indeed, methods, systems and apparatuses disclosed herein may be implemented in localized and distributed forms consistent with computing technology.
It should be noted that some of the system features described in this specification have been presented as modules to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom very-large-scale integration (VLSI) circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field-programmable gate arrays, programmable array logic, programmable logic devices, graphics processing units, or the like.
A module may also be at least partially implemented in software for execution by various types of processors. An identified unit of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions that may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together but may comprise disparate instructions stored in different locations that, when joined logically together, comprise the module and achieve the stated purpose for the module. Further, modules may be stored on a computer-readable medium, which may be, for instance, a hard disk drive, flash device, random access memory (RAM), tape, or any other such medium used to store data.
Indeed, a module of executable code could be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set or may be distributed over different locations, including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.
It will be readily understood that the components of the application, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the detailed description of the embodiments is not intended to limit the scope of the application as claimed but is merely representative of selected embodiments of the application.
One having ordinary skill in the art will readily understand that the above may be practiced with steps in a different order and/or with hardware elements in configurations that are different from those which are disclosed. Therefore, although the application has been described based upon these preferred embodiments, it would be apparent to those of skill in the art that certain modifications, variations, and alternative constructions would be apparent.
While preferred embodiments of the present application have been described, it is to be understood that the embodiments described are illustrative only and the scope of the application is to be defined solely by the appended claims when considered with a full range of equivalents and modifications (e.g., protocols, hardware devices, software platforms etc.) thereto.
