AI Technical Summary

Technical Problem

Existing technologies in contract management have problems such as low efficiency, difficulty in real-time compliance response, difficulty in tampering detection, and data security risks in centralized evidence storage. They cannot meet the business scenarios' needs for contract security, real-time compliance, and mutual trust among multiple parties.

Method used

Dynamic knowledge graphs and adversarial learning models are used to adjust the compliance of contract documents, blockchain is used to store evidence and create NFT instances, smart contracts are used to verify signature authorization and update content, and hash values ​​are used to verify the integrity of contract documents.

Benefits of technology

It achieves real-time compliance adaptation of contract terms, identifies and corrects conflicts in terms, ensures the non-tamperability of contract content, and improves the dynamic compliance and security of contract management.

Abstract

The invention relates to the technical field of block chains, and particularly provides a contract file tamper-proofing method, system and device and a storage medium, and the method comprises the steps: carrying out the compliance adjustment of a contract file through a dynamic knowledge graph and an adversarial learning model; uploading the hash value of the compliance contract file to a block chain for evidence storage; when it is detected that the contract terms are updated, synchronously updating evidence storage data in the block chain; and obtaining the evidence storage data of the target NFT instance and the corresponding contract file from the block chain, and verifying the integrity of the contract file by comparing the content of the contract file with the contract term structured data in the evidence storage data. Through technical innovation and cross-domain fusion, the core problems of dynamic compliance fault, weak tamper-proofing capability and the like in the existing contract management are systematically solved.
