The following embodiments are to further illustrate the viewpoints of the present invention, but do not limit the scope of the present invention by any viewpoint.

Please refer to FIG. 1, which is a block diagram of a real-time customized trust smart system according to an embodiment of the present invention. As shown in FIG. 1, the real-time customized trust smart system 1 includes a wearable smart device 10 and a server 20, which are signal-connected to each other. The server 20 is used to publish a smart contract on the first node N1 of the blockchain BC. The wearable smart device 10 includes a communication unit 11, a recording unit 12, an identity verification module 13, and a processing control unit 14. The communication unit 11 is used to obtain the smart contract from the first node N1 and generate a trigger signal. The recording unit 12 is used to be triggered by the trigger signal to obtain the first voice of the client. The identity verification module 13 is used to perform an identity verification on the client. When the result of the identity verification indicates a pass, the processing control unit 14 uploads the first voice to the second node N2 of the blockchain BC. The server 20 can be triggered by the processing control unit 14 to access the first voice from the second node N2 and update the smart contract according to the first voice, and upload the updated smart contract to the third node N3 of the blockchain BC.

Please refer to FIG. 2, which is a schematic diagram of an application of a real-time customized trust smart system according to another embodiment of the present invention. As shown in FIG. 2, the connection relationship between the wearable smart device 10 and the server 20 of the real-time customized trust smart system 1 is the same as FIG. 1, and the nodes (N1, N2, N3, etc.) of the blockchain BC can also be used to upload or access data, which will not be described in detail here. Continuing with the description of FIG. 1, when the result of the identity verification indicates that it is not passed, the server 20 can be triggered by the processing control unit 14 to access the result of the identity verification from the second node N2 and generate a suspicious message based on the result, and upload the suspicious message to the third node N3.

In this example, the wearable smart device 10 can be, for example, a smart watch, a smart bracelet, a smart necklace or a smart phone, and has a communication unit 11 such as an antenna unit that can realize the communication function, a recording unit 12 that can realize the recording function by using piezoelectric materials to convert air vibrations into electrical signals, an identity verification module 13 that can use the verification data in the memory (such as account and password) to verify the identity of the client, and a processing control unit 14 such as a microcontroller or a microprocessor that can perform various calculations and controls. In addition, the server 20 can be a computing device such as a computer device that can connect to the Internet and is set at the bank end.

Please refer to FIG. 3 in conjunction with FIG. 1 and FIG. 2. FIG. 3 is a flow chart of a method for instant customized trust according to an embodiment of the present invention. As shown in FIG. 3, the method for instant customized trust includes steps S10 to S18, which are respectively step S10: using the server 20 to publish a smart contract to the first node N1 of the blockchain BC; step S11: using the communication unit 11 of the wearable smart device 10 of the client to obtain the smart contract from the first node N1 and generate a trigger signal; step S12: using the triggered The recording unit 12 of the wearable smart device 10 triggered by the signal obtains a first voice from the client; step S13: the identity verification module 13 of the wearable smart device 10 performs an identity verification on the client; step S14: determine whether the result of the identity verification indicates a pass, if it passes, execute steps S15 and S16, otherwise execute steps S17 and S18. Step S18; Step S15: When the result of the identity verification indicates that it is passed, the processing control unit 14 of the wearable smart device 10 uploads the first voice to a second node N2 of the blockchain BC, and the server 20 accesses the first voice from the second node N2 and updates the smart contract according to the first voice; Step S16: The server 20 uploads the updated smart contract to the third node N3 of the blockchain BC; Step S17: When the result of the identity verification indicates that it is not passed, the processing control unit 14 uploads the result of the identity verification to the second node N2, and the server 20 accesses the result of the identity verification from the second node N2 and generates a suspicious message according to the result; Step S18: The server 20 uploads the suspicious message to the third node.

The following example is a case where a client wants to use a wearable smart device 10 to establish a trust with a bank (server 20). There are many types of trusts, such as money trusts, insurance trusts, securities trusts, public welfare trusts, and will trusts. Here, a will trust is used as an example to demonstrate that this case meets high standards of data security and immutability during the trust establishment process, but this case is not limited to this. First, the client can issue an instruction to establish a will trust through the wearable smart device 10. This instruction can be received by the recording unit 12 and transmitted to the server 20 by the processing control unit 14. In step S10, the server 20 can upload the corresponding trust form to the first node N1 of the blockchain BC in the form of a smart contract. In step S11, the communication unit 11 of the wearable smart device 10 can receive the smart contract, generate a trigger signal and transmit it to the recording unit 12. In step S12, the recording unit 12 can be triggered by the trigger signal to display a message requesting the first voice through the screen of the wearable smart device 10, or request the first voice from the client in the form of a prompt tone through the speaker, thereby obtaining the first voice.

In step S13, the identity verification module 13 may make a verification request, such as requiring the client to enter an account and password information to perform identity verification. In step S14, the identity verification module 13 may determine whether the client has passed the identity verification, such as whether the account and password information entered by the client matches the preset information. In step S15, the identity verification message is transmitted to the processing control unit 14, and the processing control unit 14 may upload the first voice to the second node N2 of the blockchain BC, so that the server 20 can further access the first voice and update the smart contract. In addition, the processing control unit 14 may also upload the information related to the identity verification together with the first voice to the second node N2 of the blockchain BC for additional confirmation by the server 20. In step S16, the server 20 may upload the updated smart contract to the third node N3. Here, the updated smart contract may include the trust information further determined by the client, and the above nodes (N1 to N3) all record the time information of the data upload to retain the complete process of the trust determination. In addition, the client may obtain the updated smart contract from the third node N3 through the wearable smart device 10, and consider further modifying the content of the contract. The relevant implementation method can refer to the previous steps S10 to S16, and the repeated description is omitted here.

On the other hand, if the result of the identity verification is not passed, that is, in step S17, the processing control unit 14 can upload the result of the identity verification to the second node N2, so that the server 20 can access the failed identity verification result from the second node N2 and generate a suspicious message accordingly. It should be noted that although the identity verification fails, the server 20 can still upload the first voice of the client together with the result of the identity verification to the second node N2, and this case is not limited to this, but the server 20 will refuse to update the smart contract based on the failed result of the identity verification. In step S18, the server 20 may upload the suspicious message to the third node N3, wherein the suspicious message may be a warning message and may include the result of the failed identity verification for future comparison and confirmation of the data of the second node N2 and the third node N3.

Based on the blockchain architecture, each node has data, hash value, and hash value of the previous node. When the data on each node is changed, the hash value of the node changes accordingly, causing the hash value of the previous node of the next node to be unable to correspond to the current node. For example, for the third version of the smart contract (V3) located at the fifth node (N5) generated by the above method, if someone wants to tamper with the contract content, the fifth node (N5) will not be able to correspond to the voice message of the client of the fourth node (N4); or when the voice message of the fourth node (N4) is changed, the hash value of the previous node of the fifth node (N5) will not be able to correspond to the fourth node, so the entire blockchain BC may be blocked and unusable. In addition, the blockchain can be shared by many users at the same time, and it is set to take a certain amount of time to change a single data. Various characteristics make it difficult to tamper with many data on the blockchain at the same time.

In addition to the security of data transmission, the credibility of the first voice provided by the client itself is another issue. Please refer to Figure 4, which is a block diagram of the identity verification module of the real-time customized trust intelligent system according to another embodiment of the present invention. In this example, the identity verification module 13 includes a voiceprint recognition unit 130, a physiological sensing unit 131, a lie detection unit 132, and a positioning tracking unit 133, wherein the voiceprint recognition unit 130 is used to perform a voiceprint recognition of the identity verification on a second voice of the client to confirm that the client's identity is correct; the physiological sensing unit 131 is used to perform a pulse detection and a blood oxygen detection on the client to record a normal pulse range and a normal blood oxygen concentration range of the client, and measure And judging whether a pulse value and a blood oxygen concentration of the client are respectively within the normal pulse range and the normal blood oxygen concentration range to evaluate whether the client's physiological state is normal; the lie detection judgment unit 132 is used to perform a lie detection test for the identity verification on the client to identify the authenticity of the first voice; the positioning tracking unit 133 is used to perform a positioning authentication for the identity verification on the client to confirm whether the client is in an abnormal position and may record the first voice unwillingly to establish a trust. It should be noted that the voiceprint recognition unit 130, physiological sensing unit 131, lie detection unit 132 and positioning tracking unit 133 included in the above-mentioned identity verification module 13 are optional. For example, the identity verification module 13 may include the voiceprint recognition unit 130, the physiological sensing unit 131, the lie detection unit 132 or the positioning tracking unit 133 alone, which is not limited in this case.

For example, the voiceprint recognition unit 130 may be a neural network pre-trained by a deep learning method. Specifically, the voiceprint recognition unit 130 may be a convolutional neural network. After the recording unit 12 receives the voice message of the client, it may perform Fourier transformation on the voice message to obtain a voice spectrum. Then, the voiceprint recognition unit 130 may analyze the voice spectrum to determine whether the voice message is the same as the voice feature previously registered by the client. In other words, the voiceprint recognition unit 130 can detect the user who impersonates others based on the voiceprint feature.

Since the wearable smart device 10 is worn on a user, the physiological sensing unit 131 can continuously measure the pulse rate and blood oxygen concentration of the user (i.e., the client) per minute, and establish a normal pulse range and a normal blood oxygen concentration range accordingly. Specifically, the physiological sensing unit 131 can alternately irradiate the arteries in the user's skin with the above two types of light, and then detect the signals received by different wavelengths through the light sensor to calculate the blood oxygen concentration. Generally speaking, if the user's pulse rate and blood oxygen concentration differ greatly from the normal range, they may be considered to be in an abnormal state and fail the test, which may cause the representativeness of the client's first voice to be questioned to a certain extent.

The lie detection unit 132 can determine whether the user is lying by measuring the user's pulse, blood pressure, respiration and skin conductivity (sweating degree). The positioning tracking unit 133 can be, for example, a global positioning system (GPS) to determine the geographic location of the user wearing the wearable device 10. Through the lie detection unit 132 and the positioning tracking unit 133, when the client wants to establish a trust, it can be determined whether the client is lying, or whether the client is in an abnormal location, or whether there are other related persons around when establishing the trust, so as to understand whether the client establishes the trust out of his own will.

It should be noted that when the result of voiceprint recognition indicates a pass, the result of identity verification may not necessarily indicate a pass; that is, the result of identity verification in this example includes the result of voiceprint recognition, and only when the result of identity verification indicates a pass will step S15 be executed.

The result of the pulse detection or the result of the blood oxygen detection performed by the physiological sensing unit 131 may be included in the suspicious message generated in step S17. It should be noted that when the results of the pulse test and the blood oxygen test both indicate a pass, the result of the identity verification may not indicate a pass; that is, the result of the identity verification in this example includes the results of the pulse test and the blood oxygen test, and only when the result of the identity verification indicates a pass will step S15 be executed.

Please refer to FIG. 7, which is a schematic diagram of a use scenario of a real-time customized trust smart system according to another embodiment of the present invention.

The result of the lie detection test performed by the lie detection determination unit 132 may be included in the suspicious message generated in step S17. It should be noted that when the result of the polygraph test indicates a pass, the result of the identity verification may not necessarily indicate a pass; that is, the result of the identity verification in this example includes the result of the polygraph test, and only when the result of the identity verification indicates a pass will step S15 be executed.

Please refer to FIG. 9 in conjunction with FIG. 3 and FIG. 4 , which is a flow chart of a method for instant customized trust according to another embodiment of the present invention.

The result of the location verification performed by the location tracking unit 133 may be included in the suspicious message generated in step S17. It should be noted that when the result of the location authentication indicates a pass, the result of the identity verification may not indicate a pass; that is, the result of the identity verification in this example includes the result of the location authentication, and only when the result of the identity verification indicates a pass will step S15 be executed.

Please refer to FIG. 10 in conjunction with FIG. 3 and FIG. 4 . FIG. 10 is a flow chart of a method for instant customized trust according to yet another embodiment of the present invention. As shown in FIG. 10 , in step S12 after step S11, the recording unit 12 can be triggered to obtain the first voice and the second voice from the client; then, step S13 is passed to step S14, wherein step S14 includes sub-steps S140 to S144, that is, the result of identity verification is determined through voiceprint recognition, pulse detection, blood oxygen concentration detection, lie detection and positioning authentication, wherein when the result of one of the voiceprint recognition, pulse detection, blood oxygen concentration detection, lie detection and positioning authentication indicates failure, the result of identity verification indicates failure and then step S17 is executed. The results of the above-mentioned voiceprint recognition, pulse detection, blood oxygen concentration detection, lie detection and positioning authentication can be included in the suspicious message generated in step S17. It should be noted that in this example, when the results of voiceprint recognition, pulse detection, blood oxygen concentration detection, lie detection and positioning authentication all indicate passing, the result of identity verification can indicate passing and execute step S15.

Through the above description, the intelligent system and method of instant customized trust in this case can establish a trust in the following way. The client releases the voice content of the smart contract to the bank through a wearable smart device, and the bank trust personnel review the voice content and send the review results back to the client. During the review process, the device regularly sends back the client's heartbeat and blood oxygen status to the bank's lie detector for inspection, and after the recording is completed, the recording file is compared with the recording retained at the time of signing the contract. After the comparison is completed, the bank trust personnel listen to the content and organize it, and then send the content back to the client for confirmation. When the principal confirms the establishment of the trust, the confirmation message is sent back to the bank. After the bank is approved by the trust personnel and supervisor, the trust setting is performed on the system. After the setting is completed, the private key is issued and sent back to the wearable smart device for storage. When the trust and will conditions are established, the device and the bank can be used to confirm and decrypt. When the principal wants to modify or cancel the trust and will, he can record again and send it back to the bank for review. Because the blockchain has a mechanism to store the transaction process, the modification process will be completely retained.

Through the above structure, the intelligent system and method for instant customized trust disclosed in this case can use blockchain as an encrypted information bridge between the principal and the trustee to record all contract modification information and identity verification information during the trust establishment process. Based on the characteristics of blockchain, this system can retain all modification records to ensure that the trust content is encrypted and stored, not easily modified, and can be traced back to protect the rights and interests of the principal, the trustee and the beneficiary. At the same time, there is no need to send a dedicated person to provide trust services in the process, which can save human resources. In addition, the system can also perform various identity verifications on the client to ensure that the client's status is normal and that the trust is established at the client's free will rather than external pressure.

Although the present invention is disclosed as above by the aforementioned embodiments, it is not intended to limit the present invention. Any changes and modifications made within the spirit and scope of the present invention are within the scope of patent protection of the present invention.
