A letter of credit is one of the important audit procedures, and the audit evidence obtained by the letter is called a Confirmation Request. The inquiry letter shall be directly sent to the third party by the auditor, and the reply letter shall be sent back directly to the auditor to avoid being falsified by the auditee and the reply letter. In addition, if the letter does not receive a response within a reasonable period of time, or in order to duplicate the validity and accuracy of the evidence, the auditor may repeat the letter, such as: a second letter, three letters, etc. And so on.

In the past, the letters were written in paper, and various manufacturers later proposed the technology of electronic letters. However, the electronic letters of various manufacturers use non-disclosure agreements, which result in the incompatibility of electronic certificates of different manufacturers, which not only causes inconvenience to auditors, but also the risk of falsification of the stored information, and cannot track the entire letter. Process, therefore, the traditional e-Cert method has problems of poor reliability and convenience.

The embodiments of the present invention will be described in detail below with reference to the drawings and embodiments, so that the application of the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Before describing the blockchain intelligent contract-based information system and method thereof disclosed in the present invention, the environment to which the present invention is applied is explained. The present invention is applied to a blockchain network that executes smart contracts. The computer devices in the blockchain network can be regarded as blockchain nodes (or simply nodes), which are connected by peer-to-peer (Peer to Peer) and used to process blockchain transactions. . In practical implementation, the computer device can be a server, a computer host, a notebook computer, a tablet computer, a smart phone, etc., for executing computer program instructions, such as the blockchain program "Ethereum". In addition, the "Organization Registration Contract", "Letter Request Registration Contract" and "Certificate Request Contract" described in the text refer to Smart Contract, which refers to the established conditions and transmission. The information is used to drive the computer program that executes the instructions. In practical implementation, the smart contract is written by a programming language such as Solidity, Serpent, LLL, EtherScript, Sidechain, etc., which can include various functions (Function ), event (Event), parameter status, etc., taking the blockchain program "Ethereum" as an example. The smart contract is compiled to obtain binary encoding and application Binary Interface (ABI) to make smart. The contract was broadcast to the blockchain network, waiting for the miner (Miner) to put the smart contract on the blockchain and get the corresponding address, thus completing the release of the smart contract through the blockchain transaction. After that, each node can execute the corresponding smart contract according to this address, and change the state of the smart contract on the blockchain and detect whether the event is triggered by different instructions. In particular, the function of executing a smart contract stores the address of another smart contract in a smart contract, such as: stored in an array. This method can be called "Registry", and the smart contract is registered in In another smart contract, two smart contracts are associated. In actual implementation, the execution (or call) function can simultaneously bring in a Universally Unique Identifier (UUID) and a contract address, and store the contract address in the array location specified by the UUID.

The following is a description of the correspondence system and method of the blockchain smart contract according to the present invention. Please refer to "FIG. 1" first, and "FIG. 1" is a letter-based system based on blockchain smart contract. The system block diagram is applied to the blockchain network 10 that executes the smart contract. The system includes: a rights end 110, a credential server 120, and an audit end 130. In actual implementation, the rights end 110, the certificate server 120, and the audit terminal 130 are all computer devices in the blockchain network 10. The authority terminal 110 is configured to initially issue an organization registration contract through the blockchain transaction to provide a storage certificate request registration contract address, where the organization registration contract includes an organization registration function and an organization registration success event. In actual implementation, the computer equipment of the authority terminal 110 is located in a government unit or an authorized private unit. In addition, the organization registration contract is used to provide a letter of registration for registration, that is, when the certificate object registers its letter of registration request registration in the organization registration contract, that is, the letter object provides the blockchain intelligence. Electronic letter of reference service for contracts.

The portion of the credential server 120 includes an initial module 121 and a return module 122. The initial module 121 is configured to request a registration contract through a blockchain transaction issuance letter to provide a storage certificate request contract address, and obtain a correspondence request registration contract address corresponding to the letter request registration contract, and execute Organize the registration function, store the obtained letter of request registration contract address in the organization registration contract and trigger the organization registration success event. In other words, the initial module 121 registers the registration request registration contract issued by the token server 120 in the organization registration contract, so that when the token server 120 is used as a correspondence object, it can provide a smart link with the blockchain. Electronic correspondence service.

The reply module 122 is configured to obtain a corresponding letter request contract according to the letter request contract address after the transaction server 120 is a token object and detects that the registration success event is triggered, and encrypt the evidence data into the letter. The license request contract is to update the letter through the blockchain transaction to request the contents of the contract and trigger the correspondence to respond to the event. In actual implementation, the evidence data may be encrypted through the audit terminal public key of the auditing end 130, and the encrypted evidence data may even be signed using the private key of the credential server 120. In addition, the loopback module 122 can learn that the auditing end 130 wants to perform the credential again after detecting that the credential request event is triggered, so that the evidence data is encrypted and embedded in the credential request contract, and is released through the blockchain transaction. Trigger a response to the event. In particular, the credential server 120 may generate an input window for providing evidence to be entered by the correspondent or to receive evidence directly from the internal system, for example, receiving the deposit balance of the auditee from the internal banking system. .

The part of the auditing end 130 includes a detecting module 131, a credential module 132 and an auditing module 133. The detecting module 131 is configured to detect whether the address of the authenticity object of the authenticity object exists in the organization registration contract when the correspondence is performed on the authenticity object, and when present, generate a correspondence corresponding to the authenticity object The contract is requested and published via a blockchain transaction to obtain the corresponding letter request contract address. In practical implementation, the letter request contract may include a verification letter for providing embedded evidence, and the verification letter embedded in the evidence data is encrypted by using the audit public key, so that the audit terminal 130 can be used by the auditing end. The private key is decrypted and audited. In addition, if the address of the document does not exist in the organization registration contract, that is, the letter object does not provide the electronic letter service of the blockchain smart contract, so the letter request contract will not be generated, but the auditor is prompted to Other ways to do the letter, such as: written letter. In particular, the auditing end 130 can generate a certificate window for setting the required correspondence content, such as balance, investment amount, payment status, credit status, etc., in order to generate a corresponding letter request contract.

The certificate module 132 is configured to execute a registration function of the letter request registration contract, store the letter request contract address in the letter request registration contract and trigger a registration success event. In other words, the auditing end 130 registers the issued letter request contract with the letter request registration contract issued by the letter server 120, and triggers the registration success event, so that the certificate server 120 is triggered by the registration success event. It is known that the auditing side 130 wants to request evidence. In actual implementation, the credential module 132 can also perform a re-request function of the credential request registration contract to perform a re-request function to re-request when the audit-side 130 re-submits the same credential object. Evidence data and trigger a request for an event.

The auditing module 133 is configured to load the evidence data from the corresponding letter request contract for decryption and audit after detecting that the correspondence response event is triggered. In actual implementation, the decryption of the evidence data is implemented using the auditor's private key of the auditing end 130. As for the auditing, the auditing personnel perform auditing operations based on the evidence data displayed after decryption.

Please refer to "2A" and "2B", "2A" and "2B" are flowcharts of the method of the method based on the blockchain smart contract, which is applied to the area where the smart contract is executed. The blockchain network 10 includes the steps of: providing the rights end 110, the message server 120, and the auditing end 130 as nodes of the blockchain network 10 (step 210); the rights end 110 is initially through the block The chain transaction issuance organization registration contract is used to provide a storage certificate request registration contract address, wherein the organization registration contract includes an organization registration function and an organization registration success event (step 220); the certificate server 120 initially passes the blockchain The transaction issuance letter requires a registration contract to provide a storage letter request contract address, and obtains a letter of registration request registration address corresponding to the letter request registration contract, and an organization registration function, and the obtained letter request registration contract address is stored to Organizing the registration contract and triggering the organization registration success event (step 230); when the auditing end 130 performs a correspondence on the authenticity object, the auditing end 130 detects the authenticity of the authenticity object of the authenticating object Whether it exists in the organization registration contract, when it exists, generates a letter request contract corresponding to the object of this letter and publishes it through the blockchain transaction to obtain the corresponding letter request contract address, and the registration letter for executing the letter request registration contract And storing the correspondence request contract address in the correspondence request registration contract and triggering the registration success event (step 240); when the token server 120 is the token object and detecting that the registration success event is triggered by the auditing terminal 130, Obtaining a corresponding letter request contract according to the letter request contract address, and embedding the evidence data in the letter request contract to update the content of the letter request contract and trigger the letter response event through the blockchain transaction (step 250); After detecting that the correspondence response event is triggered, the auditing end 130 loads the evidence data from the corresponding letter request contract for decryption and auditing (step 260). Through the above steps, the authority end 110, the credential server 120 and the audit end 130 can be set as nodes of the blockchain network 10 to execute the blockchain smart contract, and when the audit end 130 pairs the credential object When the certificate is issued, a corresponding letter request contract is generated and issued to the blockchain network 10, and a registration success event is triggered. When the certificate server 120 is a token object and it is detected that the registration success event is triggered, The evidence data is encrypted and embedded in the corresponding letter request contract, and triggers the letter response event. When the auditing end 130 detects that the letter response event is triggered, the evidence data is loaded from the corresponding letter request contract for decryption and audit.

In particular, as indicated in "Block 2B", after step 240, when the auditing end 130 re-submits the same authenticity object, it performs a re-request function of the registration request registration contract for re-requesting. The evidence data and triggers a token request event (step 241). Next, after step 250, the token server 120 detects that the token request event is triggered, encrypts the evidence data into the token request contract and issues and triggers the token response event through the blockchain transaction (step 251). . In this way, the auditing party 130 can perform the re-request function by executing the re-request function for the previous correspondence, and if the response is not received within a reasonable period of time, the second letter and the third letter can be realized. Wait, and so on.

The following is a description of the following examples in conjunction with "3" and "4". Please refer to "3" and "3" for the application of the present invention to provide a setting request in the letter window. Schematic of the content. In actual implementation, the auditing end 130 can generate a credential window 300 having an option 310 of a plurality of credential content in the credential window 300. Assume that the required letter of credit is "deposit balance" and "borrowing balance". In these options 310, the auditor can select "deposit balance" and "loan balance" by cursor or touch to make it selected. After the status, click on the confirmation component 321 to generate a corresponding letter request contract, so that the letter object can know from the letter request contract that what evidence information needs to be provided. In addition, the auditor can also click to reselect component 322 so that all options are unselected for the auditor to reselect.

As shown in Figure 4, Figure 4 is a schematic diagram of the application of the present invention to provide evidence in an input window. As mentioned above, when the token server 120 is a token object and it is detected that the registration success event is triggered by the auditing terminal 130, the corresponding letter request contract is obtained according to the letter request contract address. At this time, the certificate server 120 can generate the input window 400 as shown in "Fig. 4", and provide the evidence to be input by the letter in the input block 410, and then select the transmission element 421, and then the evidence data. After encrypting with the auditor public key, the corresponding letter request contract is embedded to update the contents of the contract through the blockchain transaction and trigger the letter response event of the letter request contract. In addition, after detecting the registration success event, you can also directly connect to the bank's internal system to check the deposit amount of the auditee, even if it matches the deposit amount provided by the auditee, and then you will get it. The result is used as evidence, and the contents of the letter request contract are also updated in the form of blockchain transactions, thereby achieving the purpose of replying the letter. In particular, when the evidence data exceeds the size allowed by the blockchain, it can be combined with the Distributed File System, such as "IPFS", "Ethereum Swarm", etc., so that only smart contracts are stored. The UUID corresponding to the evidence data, and the evidence data corresponding to the UUID is stored in the distributed file system. In this way, both the auditing end 130 and the credential server 120 can access the encrypted large data through the distributed file system. In addition, in order to prevent the letter object from responding to the letter but not confirming the correctness of the information, the auditing end 130 may not present the correct amount or other information on the letter request contract, but directly request the letter object to input the correct amount. Or provide other information to reduce the risk of incorrect data.

In summary, it can be seen that the difference between the present invention and the prior art is to perform the blockchain intelligence by setting the authority end 110, the credential server 120, and the auditing end 130 as nodes of the blockchain network 10. The contract, when the auditing end 130 makes a letter to the authenticity object, generates a corresponding letter request contract and issues it to the blockchain network 10, and triggers the registration success event, when the token server 120 is a token object and Detects When it is detected that the registration success event is triggered, the evidence data is encrypted and embedded in the corresponding correspondence request contract, and the correspondence response event is triggered. When the auditing end 130 detects that the correspondence response event is triggered, the contract is requested from the corresponding letter. The evidence data is loaded for decryption and auditing, and the technical problems of the prior art can be solved by using a technical means, thereby achieving the technical effect of improving the reliability and convenience of the electronic certificate.
