Description

Blockchain-based Cryptographic Online Platform for Issuance of a Digital Postage Stamp (DPS) and Control over a DPS Issued

Field of the invention

The invention relates to platform-based data access security systems, for example, those using keys or rules to control access to a system of files or objects, in particular, through a distributed file system or database, and can be used to build an advanced digital cryptographic online platform for the shared payment of franking services (franking) based on the Blockchain technology, issuance of tokens to pay for franking services, and control thereof through said platform. Franking means the payment for postal services using franking notes, such as postage stamps.

Background of the invention

The format of a digital postage stamp (DPS), as offered today by many postal services worldwide, allows for the use of this tool solely as a means of payment for postal services. For example, Royal Mail, the UK postal service, uses a digital postage stamp called SmartStamp. This DPS is available for purchase through the Internet and is used by printing an image or an encoded image (e.g., a QR code) thereof directly on an envelope from a computer. The proposed cryptographic online platform is designed for the DPS issuance and circulation using the blockchain technology and can significantly extend the functionality of the DPS as a tool as well as to enhance the security and cost-effectiveness of the DPS use. In terms of engineering, the DPS used by the claimed cryptographic online platform is configured as a digital token. Such a digital token is an entry in the distributed blockchain register generated by the claimed platform. The token contains all the information necessary to use it fully as a DPS. In a broader functional sense, the proposed platform is suitable for the issuance of a DPS, which is an encoded digital image having the form of a classic postage stamp in a certain digital format. The postal service of a specific country is an issuer of such DPS and, as such, determines the nominal value of the DPS issued. Making a DPS as a token linked to a blockchain network allows for securing the right of ownership to a DPS or simplifying the DPS replacement, and at the same time, provides functionalities, such as payment for postal services using a DPS as well as collection, purchase, sale, and exchange of DPSes.

Description of the prior art

The online system for the issuance of postal service payment instruments (VBI), similar to electronic postage stamps, is the prior art described in Application US 2010/0042545 Al, published on February 18, 2010 (Applicant - STAMPS.COM (US)). The system comprises cryptographic modules and a central database. The modules encrypt information from the central database for all VBI clients online and are capable to prevent unauthorized users from accessing the databases. The described solution is aimed at improving the security of VBI usage.

The prior art also describes the postage payment methods based on the blockchain technology described in Application CN 108921526 A published on November 30, 2018 (Applicant - GUANGDONG POST MAIL EXPRESS SERVICE CO LTD). Postage stamps are issued at a certain stage of mailing. The invention also aims to improve the security of mailing and to prevent postage stamp frauds.

Further, the prior art describes the method of franking digital documents whereunder the paid digital postage stamp is used as a means of franking (publication of International Application W02011110406 (Al) dd. September 15, 2011 (Applicant - SWISS IT MAN AG)). Before outputting the data (in digital or physical form) in a digitally accessible document, a digital postage stamp is generated as a postage stamp in accordance with applicable country-specific rules by communicating with the provider's server or network node belonging to postal service providers over communication lines. Once the validity of a paid digital postage stamp has been successfully verified, a digital document, which corresponds to the digital form of the processing device, is applied and is physically printed by a printer for a postal item. Essentially, the Application describes the issuance of a digital postage stamp without using the blockchain technology.

A digital e-mail management system described in Application US 2006101121 A1 published on May 11, 2006 (Applicant - SENECHALLE ANNETTE (US)) is also known in the prior art. The system provides for a database, which is used in conjunction with a digital stamp generator, capable of generating branded digital stamps upon user request. The invention also discloses an application method in classic postal systems which do not provide for a payment option using a built-in or discrete e-mailing agent. The invention further discloses a system and methods for labeling and marking digital stamps in e-mails. The described digital postage stamp is used to identify a sender and helps to prevent spamming.

A method of payment for online postal services by identifying a client with the blockchain technology is also known in the prior art and is described in US Patent 10223736 B1 published on March 05, 2019 (Applicant - PSI SYSTEMS INC (US)). Said method comprises requesting for printing a postage stamp, providing postage stamp data by the server computer system to an embedded application on a client computer, and, upon verification of the token validity, the embedded application performs at least a part of the request by visualizing a postage stamp through a printer when the application communicates with a client computer, without postage stamps being displayed on the client computer display device. The method is intended to ensure the validation of a postage payment transaction using the blockchain technology and user device management, however it does not provide for the operation of a digital cryptographic online platform.

A blockchain platform for the generation of digital tokens intended for sale and associated with the amount of a specific physical asset is also known in the prior art and is described in Application EP 3432240 A1 published on January 23, 2019 (Applicant - CHICAGO MERCANTILE EXCHANGE INC (US)). The Application generally describes an approach to the issuance of any digital asset using the blockchain technology, however it does not describe how the platform is adapted specifically for the issuance of a digital postage stamp followed by control of the postage stamp so issued and implementation of functions specific to a postage stamp as a means of payment for services of a DPS issuing postal office of a specific country.

A digital online postal service built on the blockchain technology is also known in the prior art and is described in the White Paper "Envilope. The World's First Blockchain Postal Service", Version 4.0, May 4, 2018. The digital online postal service enhances the security of sending and receiving postal items through Envilope blockchains. The service allows for the issuance of proprietary digital postage stamps that accompany Envilope blocks and can be issued upon user request and can be sold or exchanged. Digital postage stamps are issued by particular software integrated into the service. The described service uses the blockchain-based issuance of digital postage stamps; however such postage stamps are not used as a means of payment for franking services.

The blockchain-based platform for the issuance of digital postage stamps as digital tokens, including the issuance through national postal services, to prevent losses from postage stamp fraud is taken as a prototype. The platform also allows for the control over digital stamps so issued (Yury Yanovich, Igor Shiyanov, Timur Myaldzin, Ivan Prokhorov, Darya Korepanova and Sergey Vorobyov "Blockchain- Based Supply Chain for Postage Stamps" published on November 15, 2018). The disadvantage of the known platform is the lack of reliable and easy generation of tokens used as digital postage stamps, and the lack of a cancellation mechanism for the issued digital postage stamp followed by making appropriate changes in the blockchain register, etc.

Another drawback, which is common for all known platforms, services, and methods issuing and using DPSes, is poor functionality of the DPS issued, such as securing the right of ownership to a DPS, purchase/exchange/sale of DPSes, including, to some extent, collecting DPSes and similar functionality inherent in a postage stamp as a means of franking.

Terms and definitions

The blockchain technology is a system for organizing and storing data on transactions, agreements, and contracts within the system which is presented in a cryptographic form through chains of information blocks. The blockchain accumulates all the data to form a database being updated on an ongoing basis. In such a database, no data can be deleted or replaced/substituted in an information block. The blockchain database supports an unlimited number of transactions. Since the chain of information blocks does not use a central server, the blockchain network is a decentralized virtual machine using a set of so-called nodes - separate computer tools, being nodes of the blockchain network and forming such a decentralized virtual machine through the Internet - as a server. The blockchain technology features transparency, since transaction or smart contract data, etc. are stored in the open access and, as such, cannot be changed, and reliability because the consensus of blockchain nodes is required to enter new data to the blockchain, allowing for the filtration of transactions and recording of legitimate transactions only.

Summary of the invention

The object of the invention is to create an online platform for the issuance of a digital postage stamp (DPS) and for the control of the issued digital postage stamp to enhance the security of the organization and storage of DPS issuance data by using cryptography for encrypting data associated with the issuance and circulation of a digital postage stamp and the reliability of transactions behind the issuance and circulation of a digital postage stamp by using blockchain-based smart protocols, and to simplify such transactions by automatic fulfillment of the smart protocol. An additional object is to extend the functionality of DPS use by running a cryptographic online platform suitable for blockchain-based DPS issuance, collecting or purchase/sale/exchange of issued DPS, and making payments for postal services. According the invention, this object is achieved by a blockchain-based cryptographic online platform for the issuance of a digital postage stamp (DPS) and control over the DPS so issued, which comprises a platform server configured for data exchange with a set of nodes connected to a continuous blockchain sequence system and a set of software modules for the control of at least one cryptocurrency, with at least one user device software module, and with at least one DPS issuance server. Each set of nodes is configured for data exchange with a set of cryptocurrency control software modules and at least one DPS issuance server. The platform server is configured for making entries in the digital register of issued DPSes distributed across a set of nodes connected to the continuous blockchain sequence system. The platform server is also configured for the issuance of DPS by dividing the digitized image of the issued postage stamp, received from the DPS issuance server, into proportional parts followed by recording of each part of the digitized image in separate information blocks of a continuous sequence of blockchains and generating a digital token in the form of an entry in the said distributed register. The platform server is further equipped with at least one database of issued DPSes viewable and searchable through a user device software module configured for a transaction of transferring information blocks of the continuous blockchain sequence system through a software module for the control of at least one cryptocurrency and the generation of a transaction hash code followed by the code entry to the distributed register. The platform server is also configured for making changes in the distributed register to reflect the validity status of the postage stamp.

The technical result of using the cryptographic online platform described above is to improve the security and transparent accounting of all DPS transactions, and to secure the right of ownership to DPSes for all platform users through smart contracts based on the blockchain technology. An additional technical result is the implementation of DPS visual perception in high digital resolution to allow for the collection of DPSes using the platform elements. Another technical result is the use of means of withdrawing DPS from the accounting system and DPS conversion into the format that allows for the application of a DPS on a postal item and ensures that this payment method is acceptable by the DPS issuing postal service. A further technical result is the use of DPS purchasing/exchanging/selling tools by logged-in and authorized platform users.

According to one preferred embodiment of the platform, upon the issuance of a new DPS, an entry in the digital register of issued DPSes may include the generation of a smart contract of the issued DPS with a unique address using a continuous blockchain sequence system, whereby the data acquisition from a DPS owner is simplified.

According to another preferred embodiment of the platform, the smart contract of the issued DPS may contain a field with DPS metadata and/or DPS owner identifier and/or DPS value data, and the platform server is configured to record a unique smart contract address to the database of issued DPSes to minimize computing capacity required for the purchase/exchange/sale of DPSes or parts thereof.

According to yet another preferred embodiment of the platform, the platform server can be configured for making entries in the digital register of issued DPSes on the value of each digital token, equivalent to the number of minimum information units of the information block allocated to each part of the digitized image. This allows for achieving enhanced security of the storage of a DPS digital image and, at the same time, creating a mechanism for performing any operations both with the whole DPS and parts thereof.

According to yet another preferred embodiment of the platform, the number of information blocks may be equivalent to the value of the DPS issued and is determined by that one digital token is equivalent to one minimum nominal value of the monetary unit, which further enhances the reliability of transactions with the whole DPS, since only a set of blocks allows for making transactions with the whole DPS and its value.

According to yet another preferred embodiment of the platform, the platform server can be configured for making changes in the distributed register concerning the validity of a postage stamp by reading a QR code of a DPS on a postal item, followed by the generation of a transaction hash code and making an entry in the distributed register-this simplifies the use of a DPS for the payment of postal services of the DPS issuing country and data registration within the postal service system upon DPS withdrawal (cancellation).

According to yet another preferred embodiment of the platform, the QR code of the DPS may contain the data of the owner of the software module for the control of at least one cryptocurrency and/or the data on the DPS value and/or an e-mail address of the owner of the software module for the control of at least one cryptocurrency, which facilitates the data registration within the platform upon DPS withdrawal (cancellation).

According to yet another preferred embodiment of the platform, the platform server can be configured for the transmission of the data of a QR code reading point to an e-mail address of the owner of the software module for the control of at least one cryptocurrency to complete the DPS withdrawal (cancellation) operation.

A blockchain-based cryptographic online platform for the issuance of a digital postage stamp (DPS) and control of a DPS so issued, as shown on the general flowchart in FIG. 1, comprises a platform server (1), a set of nodes (2), a set of software modules for the control of at least one cryptocurrency (3), and at least one user device software module (4). Each node of the set (2) is configured for data exchange with a set of cryptocurrency control software modules (3) and with at least one DPS issuance server (5). The set of nodes (2) is connected to a continuous blockchain sequence system (6). A network (platform) for the creation of blockchain technology based decentralized online services operating on smart contracts, for example, Ethereum (https://www.ethereum.org/). is used as the continuous blockchain sequence system (6).

The platform server (1) is configured for data exchange with said set of nodes (2), set of software modules for the control of at least one cryptocurrency (3), user device software modules (4), and DPS issuance server (5), which is a postal service server.

Whenever a new DPS is issued, an entry in the digital register of issued DPSes involves the generation of a smart contract for the issued DPS with a unique address using the continuous blockchain sequence system (6). A smart contract of the issued DPS contains a field with DPS metadata and/or DPS owner identifier and/or DPS value data. The platform server (1) is configured to record a unique smart contract address to the database of issued DPSes.

The platform server (1) is configured for making entries in the digital register of issued DPSes, distributed across the set of nodes (2) connected to the continuous blockchain sequence system (6). The platform server (1) is also configured for DPS issuance by dividing the digitized image of the issued postal stamp from the DPS issuance server into proportional parts, followed by recording each part of the digitized image in separate information blocks of a continuous sequence of their chains and generating a digital token in the form of an entry in the said distributed register. The platform server (1) is further equipped with at least one database of issued DPSes viewable and searchable through the user device software module (4). The user device software module (4) is configured for a transfer transaction of information blocks of the continuous blockchain sequence system (6) through the software module for the control of at least one cryptocurrency (3) and for the generation of a transaction hash code followed by entering the hash code in a distributed register. The platform server (1) is configured for making changes in the distributed register to reflect the validity of the postage stamp. Also, the platform server (1) is configured to enter the value of each digital token, which is equivalent to the number of minimum units of information in the information block allocated to each part of the digitized image, in the digital register of issued DPSes. The number of information blocks is equivalent to the value of the DPS issued and is determined by that one digital token is equivalent to one minimum nominal value of the monetary unit, for example, one digital token is equivalent to one US cent.

To implement the DPS "cancellation" mechanism, i.e. the function of making payment for postal services rendered by a DPS issuing postal service, the platform server (1) is further configured for making changes in the distributed register to reflect the validity status of the postage stamp by reading a QR code of a DPS on a postal item followed by the generation of a transaction hash code and making an entry in the distributed register. The QR code on the postal item contains the data of the owner of the software module for the control of at least one cryptocurrency and/or the data on the DPS value and/or an e-mail address of the owner of the software module for the control of at least one cryptocurrency. For this purpose, the platform server (1) is configured for the transmission of the data of a QR code reading point to an e-mail address of the owner of the software module for the control of at least one cryptocurrency. An example of using a cryptographic online platform for the issuance of a digital postage stamp (DPS) and control of a DPS so issued using the platform illustrated in FIG. 2 is described below.

A DPS is generated and issued by the DPS issuance server (5). A country's postal service is a DPS issuer. The authorization for DPS generation and placement on a cryptographic online platform is given through the DPS issuance server (5). A DPS is generated as follows: a sample of a physical DPS image is sent for digitization, where it is scanned, for example, with a resolution of 600 dpi in a .png format. The scanned DPS image is then recorded in the continuous blockchain sequence system (6), such as the Ethereum blockchain system. A blockchain-registered DPS is hosted on a cryptographic online platform for subsequent use by platform users, in particular through the set of software modules for the control of at least one cryptocurrency (3), the set of user device software modules (4), and the DPS issuance server (5).

This is followed by the process of generating a digital token in the form of an entry in the specified distributed register and making entries in the digital register of issued DPSes on the value of each digital token which is equivalent to the minimum information units of the information block allocated to each part of the digitized image. The number of information blocks is equivalent to the value of the DPS issued and is determined by that one digital token is equivalent to one minimum nominal value of the monetary unit. The process of determining the number of information blocks to be allocated to each DPS depending on its value determined by the postal service upon issuance, is illustrated in FIG. 3, namely: based on the DPS value, wei blocks are allocated in the equivalent of 1 block = 1 cent (wei block is the smallest indivisible share of the Ethereum network information block). The uniqueness of the generation process lies in the proportional division of the size of a digital image (divided into parts) with subsequent recording of the image (a part thereof) in each information block of the continuous blockchain sequence system (6). As a result, a DPS can only be used in its entirety through the entire set of information blocks it is divided. This enhances data uniqueness and reliability of the digital image storage, as well as allows for any operations with both the whole DPS and parts thereof. The control over a DPS issued involves the purchase, sale, exchange, auction, or payment of postal services. DPSes can be purchased both in the primary market, i.e. from a country's postal service, and in the secondary market, in particular, from other platform users, through the user device software module (4). The user logs in through the user device software module (4) and the platform server (1). To purchase a DPS in the primary market from the postal service, a user replenishes his/her account. Actual cash is debited from the user card and credited to the actual user account on a cryptographic online platform. DPSes are viewable and searchable through the user device software module (4) and the platform server (1), for example, by browsing the web page of the DPS store operated by the country's postal service. When purchasing a DPS and debiting the user account on the platform, a DPS becomes available in one of the sections of the user device software module (4). When a DPS is purchased in the secondary market, the platform receives a user request for the desired DPS parameters through the user device software module (4) and places the request so received via the platform server (1) through its interface. If the parameters of the required DPS match those of the one offered for sale, an automatic smart contract transaction is made and is followed by making changes in the continuous blockchain sequence system to change the DPS owner and write off the payment from the user account for the DPS purchased. The DPS so purchased becomes available in one of the sections of the user device software module (4). DPSes are sold in the secondary market following the full user verification through the interface of the platform server (1) with the steps similar to those done to purchase DPS. DPSes are exchanged through the interface of the user device software module (4).

DPSes are also used to pay for postage to the postal service of the DPS issuing country by withdrawing a DPS from circulation followed by making the respective entry in the digital register of issued DPSes and the database of issued DPSes through the platform server (1). In this case, the DPS is registered by the DPS issuance server (5) as a DPS which was used for payment (cancelled). The DPS cancellation process is illustrated in the flowchart shown in FIG. 4. Technically, the DPS is cancelled when three events have occurred. For event 1, the issued DPS is printed in a physical form, for example, in the form of 2 blocks on a single sheet of paper: block 1 with a visual display of the DPS and block 2 with a QR code containing the DPS details, in particular, the information on the owner of the software module for the control of at least one cryptocurrency and/or DPS value data and/or the e- mail address of the owner of the module for the control of at least one cryptocurrency (examples of blocks 1 and 2 are given in Fig. 5). No changes in the continuous blockchain sequence system are done when blocks 1 and 2 have been printed out. For event 2, the printed DPS is applied to an envelope. When a DPS gets a postal service operator (a post office, etc., which is a member to the claimed platform), the QR code is read automatically or manually, for example, with a scanner. The moment of reading is considered as the beginning of the transfer of information blocks through the software modules for the control of at least one cryptocurrency (3) between the user and the platform. As a result of QR code reading, a transaction hash code is generated in the continuous blockchain sequence system. The transaction hash code is then sent to the e-mail address of the owner of the software module for the control of at least one cryptocurrency and is recorded in the database of issued DPSes. If the DPS is sent through multiple operators, the information blocks are recalculated and distributed among all operators in a proportionate manner. If the software module for the control of at least one cryptocurrency (3) of the user is invalid or if the DPS is not available to the owner, the DPS is returned to the owner in accordance with the rules of operators. Event 3 is considered to have occurred when an intermediate or end point of the operator receives the DPS. Upon receipt, the QR code is read automatically or manually. After reading and receiving the transaction hash code, the software modules for the control of at least one cryptocurrency (3) are then checked for the transfer of cryptocurrency between the user and the platform. Each time the QR code is read, the operator sends the DPS location to the e-mail address of the owner of the module for the control of at least one cryptocurrency. After delivery of the DPS to the recipient, the entire information block of the continuous blockchain sequence corresponding to the DPS is canceled through the DPS issuance server (5) and is prepared for the use of next DPSes.

Thus, the invention enhances the security of the organization and storage of DPS issuance data, simplifies the performance of these transactions by automatic fulfillment of the smart protocol, and extends the functionality of DPS use.
