Abstract
The invention discloses a judicial data evidence-storing method based on a block chain, which aims to enable contract participants, third-party electronic contract providers, courts, arbitration committees and notarization departments to participate uniformly, enable the parties to achieve consensus and enable a judge to make a decision quickly aiming at a problem when disputes occur.
Description
Technical Field
The invention relates to the technical field of information, in particular to a judicial data evidence storage method based on a block chain.
Background
The blockchain technology is a technical scheme for decentralized and collective maintenance of a distributed account book, and is essentially a distributed database system with a plurality of nodes participating together, the blockchain is not a single technology, but a result of multi-technology integration, a reliable and difficult-to-tamper account book record is maintained by using the blockchain, trust risk can be reduced, and maintenance cost of many participants is effectively reduced. When the data is stored through the block chain, the consensus among multiple parties is required to be obtained, and the data cannot be falsified or forged after the data is chained.
In the existing contract system, if the paper version is adopted for signing, the authenticity of the contract cannot be ensured after both parties sign the contract, the contract is easy to be falsified and lost, and when disputes occur, a large amount of manpower and material resources are consumed for judging the authenticity of the contract, which is very troublesome. If the electronic contract system is adopted, the contract is stored in a centralized database of a third party, the third party may modify data, the trust problem is easy to generate, and when disputes are generated, the verification speed of calling the result from the third party is low, and the efficiency is low.
Disclosure of Invention
In view of the defects of the prior art, the invention provides a judicial data evidence storage method based on a block chain, which enables contract participants, third-party electronic contract providers, courts, arbitration committees and notarization departments to participate uniformly, enables the parties to achieve consensus, and enables a judge to make a decision quickly aiming at problems when disputes occur.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a blockchain-based judicial data evidence-storing method, the method comprising:
s1, the service side calls the electronic contract system and signs with the user to generate an electronic contract;
s2, the electronic contract system calls a block chain SDK related interface, stores the signed electronic contract hash value on a judicial evidence storing chain, and broadcasts and verifies the electronic contract hash value to the whole network;
s3, in the verification process, the nodes on each block chain receive the verification information and call the intelligent contract for verification;
s4, after the verification is passed, each storage node obtains a string of hash certificate storage numbers for verification in the future; the segment of code will be stored in the block where the block chain is packed continuously;
s5, when dispute occurs, service direction adjudication, notarization, and the identification institution submits contract, deposit number and other related information;
and S6, when the sanction, notarization and authentication organization needs to authenticate the authenticity of the contract in the auditing process, the hash value of the contract stored in the block chain is obtained by addressing the provided certification storage number on the block chain.
S7, comparing the hash value of the submitted contract with the hash value stored in the block chain through the intelligent contract, authenticating the authenticity of the contract, and showing the authentication result in the whole network.
And S8, opening an evidence chain according to the identification result to carry out judicial judgment, recording the hash value of the referee document on the block chain, and broadcasting and verifying the hash value to the whole network for future inspection.
It should be noted that after the business party signs a contract with the user, the clear text information of the contract can be uploaded in the contract uploading process, so that in the arbitration process, the contract clear text and the storage hash arbitration can be directly invoked without the user providing the contract.
It should be noted that, in the process of uploading the contract, the address of the contract stored in the electronic contract platform may also be hashed and uplinked, so that when the contract is called, the user does not need to provide the contract, and the hash address can be directly used to address and call the contract plaintext.
The invention has the beneficial effects that:
1. the uplink contract is not tamper-evident. Through the characteristics of a block chain timestamp, distributed storage, an encryption algorithm and the like, the hash value changes when the contract content is modified arbitrarily after the contract hash is linked, so that the content cannot be tampered once the contract hash is linked, and the authenticity of the contract is ensured.
2. The uplink contract is not deletable. The hash of the contract is stored in multiple parts on the chain, and any part cannot be deleted completely, so that the data security is guaranteed.
3. The multiple parties are witnessed. The business party, the notarization department, the judicial appraisal center, the court, the arbitration committee and the electronic contract platform are all linked nodes, data is stored in multiple parties, all parties can achieve consensus through certain data management standard requirements, and the whole flow credibility problem of the electronic contract in generation, storage and use is jointly guaranteed.
4. High safety. Only the hash value of the contract is uploaded to be stored on the block chain, the plaintext of the contract is not uploaded, and all parties verify through zero knowledge proof, so that privacy disclosure is prevented, and data safety is guaranteed. .
