DETAILED DESCRIPTION OF THE EMBODIMENTS It is very important for an electronic contract as a credential to have immutability and integrity, especially when a court trial is involved. This application provides a blockchain electronic contract management system based on immutability and traceability of the blockchain technology.
FIG. 1 shows a schematic structural diagram of a blockchain electronic contract management system, including an electronic contract platform, a blockchain deposit network, and a vetting network platform, where the electronic contract platform, the blockchain deposit network and the vetting network platform are connected through a network.
The blockchain electronic contract management system in this application manages an electronic contract by three parts, which respectively are: deposit management, forensics management, and checking management.
In this embodiment, an interaction between case filing in a court and the blockchain electronic contract management system is taken as an example for description.
FIG. 2 shows a logical block diagram of deposit management of a blockchain electronic contract management system. The electronic contract platform uploads electronic contract-related data to the blockchain deposit network. Specifically, the electronic contract platform verifies the electronic contract-related data, and after the verification is passed, encrypts and signs the electronic contract-related data; uploads the encrypted and signed electronic contract-related data to a node of the blockchain deposit network; and synchronously records valid information of the electronic contract. The blockchain deposit network verifies the received electronic contract-related data, and synchronizes the electronic contract-related data to a blockchain of the blockchain deposit network.
In this application, an electronic contract-related party performs related operations for the electronic contract through the electronic contract platform, including online conclusion and processing of the electronic contract such as signing, renewal, modification, and termination, including but not limited to identity authentication, signing, deposit and forensics of the electronic contract, and other related operations, to deposit the electronic contract in the blockchain deposit network.
After depositing the electronic contract, the electronic contract- related party may locally download and save the electronic contract-related data.
The electronic contract-related data may include basic information of the electronic contract, an electronic contract certificate, and transaction data. A user enters the basic information of the electronic contract according to requirements of the electronic contract platform on format of deposit data. The basic information of the electronic contract includes user registration information, personal identity information, enterprise real- name information, digital certificate issuing information, deposit information about willingness, contract signing information, and system log information. The electronic contract certificate is generated by the electronic contract platform, content of which may include information such as deposit number of the platform, a depositor, deposit content, deposit size, deposit time, deposit hash, a judiciary deposit number, and inspection by code scanning. At the same time, a transaction is constructed. Transaction- involved parties are a user and the electronic contract platform, may provide deposit proofs for the electronic contract, and perform a hash algorithm on the transaction, to generate transaction data. Finally, the obtained electronic contract-related data is generated as a data block and 1s synchronized to the blockchain.
For example, the electronic contract platform has professional knowledge and is capable of providing technical services, can verify authenticity and validity of the electronic contract, and may verify relevant information of the electronic contract, which may also be verified by other relevant authorities. The authorities include but are not limited to an electronic certification service authority, a notary authority, a judicial authentication authority, a third-party electronic contract or blockchain deposit service platform, and other authorities capable of providing verification. After the verification, the electronic contract-related data is performed with encryption, time stamp generation, and signing, and is synchronized to the blockchain deposit network.
Meanwhile, the electronic contract platform records the valid information of the electronic contract, where the valid information includes, but is not limited to a contract name, contract number, type of the contract, and identity information of the electronic contract-related party; and establishes a corresponding relationship between the valid information of the electronic contract and a transaction hash value of the electronic contract. In this way, a corresponding transaction hash value of the electronic contract may be obtained according to the valid information of the electronic contract. A search for the electronic contract-related data is conducted by using the hash value through the blockchain deposit network, to query and download the electronic contract in subsequent forensics work.
Signing the electronic contract-related data includes signing by the user and signing by the electronic contract platform, to verify authenticity and validity of the data. After the related operations for the electronic contract are completed by the electronic contract-related party at the electronic contract platform, and are verified by the electronic contract platform or a third-party authority, the electronic contract-related data is digitally signed by both the electronic contract-related party and the electronic contract platform. The electronic contract platform encrypts and then uploads the electronic contract-related data to a node of the blockchain deposit network. The node of the blockchain deposit network verifies validity, integrity, and legitimacy of the electronic contract-related data by public keys of the electronic contract-related party and the electronic contract platform. After the verification is passed, the electronic contract- related data is generated as a data block, and is synchronized to a blockchain verification network.
The electronic contract-related party needs to first deposit the electronic contract-related data at the electronic contract platform. In this application, blockchain is used for data deposit, and relevant data is uploaded after being encrypted and signed. Based on characteristics of the blockchain such as immutability and distributed storage, legitimacy, integrity, and validity of data may be ensured; and the data may be saved for any length of duration without being lost. After the data is effectively saved by the electronic contract-related party through the electronic contract platform, guarantee and legal support for implementing of the following related contracts of the electronic contract may be provided.
FIG. 3 shows a logical block diagram of forensics management of a blockchain electronic contract management system. The vetting network platform receive a case-filing application and electronic-contract credential data from an electronic contract-related party, and sends a forensics request to the electronic contract platform. The electronic contract platform receives the forensics request sent by the vetting network platform, and obtains electronic contract-related data from the blockchain deposit network. The blockchain deposit network sends the electronic contract-related data corresponding to the forensics request to the electronic contract platform.
The electronic contract platform transmits the electronic contract-related data to the vetting network platform.
Herein, the electronic contract-related data provided by the electronic contract-related party may come from a source file locally saved by a user of the electronic contract platform, or may be re-obtained through the electronic contract platform.
When the vetting network platform sends the forensics request to the electronic contract platform, for security of data transmission, the electronic-contract credential data is encrypted, and is signed by using a private key of the vetting network platform for identity verification. The encrypted and signed electronic-contract credential data is transmitted to the electronic contract platform, to implement the forensics request.
After the electronic contract platform is configured to receive the forensics request sent by the vetting network platform, verify the electronic- contract credential data by using a public key of the vetting network platform; and, decrypt the electronic-contract credential data after the verification is passed and perform query based on the electronic-contract credential data. The vetting network platform provides identity authentication while sending a request to the electronic contract platform by a private-key digital signature. After identity verification of a sender of the forensics request by the electronic contract platform is passed, the electronic contract-related data is queried. Data security may be ensured by encrypting and signing the electronic contract-related data.
The electronic contract platform obtains valid information of an electronic contract based on the electronic-contract credential data, and determines whether the electronic contract-related data of the electronic contract corresponding to the valid information is in the blockchain deposit network; if it is determined that the electronic contract-related data exists,
downloads the electronic contract-related data, and verifies validity, legitimacy, and integrity of the electronic contract-related data; and if it is determined that the electronic contract-related data does not exist, feeds back to the vetting network platform that query cannot be performed.
The electronic-contract credential data provided by the electronic contract-related party includes the valid information of the electronic contract, such as contract number and a contract name. A transaction hash value corresponding to the electronic contract-related data is obtained based on the valid information, so that the electronic contract-related data may be looked up by using the hash value. The valid information of the electronic contract is saved while the electronic contract platform performs a deposit, and thus a query may be performed first, based on the valid information, on whether data exists , and then the electronic contract-related data in the blockchain deposit network may be downloaded, thus improving efficiency and accuracy of data searching. After the validity of the electronic contract- related data is verified, the electronic contract-related data is decrypted by using a private key of the electronic contract platform, so that the validity, the legitimacy, and the integrity of the electronic contract-related data is verified.
The electronic contract platform transmits the electronic contract- related data to the vetting network platform, encrypts the electronic contract-related data by using a public key of the vetting network platform, and signs the electronic contract-related data by using the private key of the electronic contract platform. Before transmitting the electronic contract- related data to the vetting network platform, the electronic contract platform may also encrypt and sign the electronic contract-related data, to ensure security of data transmission.
When the electronic contract-related party needs to fulfill contract- related obligations through a court, the electronic-contract credential data may be submitted as evidence for filing a case and applying for filing a case. Moreover, after receiving the application and the evidence for filing a case of the electronic contract-related party, the vetting network platform may implement the forensics request through the electronic contract platform. After verifying identity on the forensics request, the electronic contract platform may obtain the electronic contract-related data through the blockchain deposit network.
FIG. 4 shows a logical block diagram of checking management of a blockchain electronic contract management system. The vetting network platform checks electronic-contract credential data based on electronic contract-related data; and after the check is passed, transmits the electronic-contract credential data to a trial terminal as evidence.
The vetting network platform verifies the electronic contract- related data by using a public key of the electronic contract platform; decrypts the electronic contract-related data after the verification is passed; and checks whether the electronic contract-related data matches with the electronic-contract credential data.
The vetting network platform checks the electronic-contract credential data provided by an electronic contract-related party; when the check succeeds, determining that an application and evidence for filing a case of the electronic contract-related party are valid, transmits a checking result and the evidence for filing a case to the trial terminal, so that the verifying and collecting of the evidence for filing a case may be achieved by the trial terminal. Finally, trial efficiency of the court for an electronic contract case 1s improved.
The electronic contract-related data is decrypted after identify verification of a sender thereof is passed. After the decryption, the electronic-contract credential data provided by the electronic contract- related party is compared with the electronic contract-related data, so as to check whether the electronic-contract credential data provided by the electronic contract-related party is true and valid. The comparison of the data herein may be determined through comparison between digital digests of the electronic-contract credential data and the electronic contract-related data. If the check is passed, the electronic-contract credential data may be sent to the trial terminal as evidence for filing a case.
According to this application, by saving the electronic contract- related data in the blockchain verification network, the validity, the legitimacy, and the integrity of the electronic contract are ensured based on immutability, leaving tracks throughout the process, traceability, and other characteristics of the blockchain technology. Accordingly, the electronic contract-related data may serve as evidence in a judicial trial. Moreover, when the vetting network platform requires evidence for filing a case, the forensics request may be raised to the electronic contract platform based on the electronic-contract credential data provided by the electronic contract- related party. The electronic contract-related data corresponding to the evidence for filing a case is queried and downloaded through the electronic contract platform while the validity, the legitimacy, and the integrity of the electronic contract-related data are verified. In this way, excessive intermediate systems of electronic evidence are reduced for the trial terminal of the court, and risks of evidence tampering are avoided. At the same time, intelligent checking is further provided, to determine authenticity of the electronic-contract credential data submitted by the electronic contract-related party, reduce workload during a case trial, and improve judicial efficiency.
