Abstract
The present application provides a transaction-based electronic contract forensics method and system: when a user wants to perform forensics for an electronic contract in a blockchain digital deposit platform, initiating, by a present electronic contract platform, a forensics request for the electronic contract; obtaining, by the blockchain digital deposit platform, the forensics request and querying deposit information; obtaining a transaction hash value of the deposit information after the deposit information is queried; querying a deposit transaction corresponding to the deposit platform; obtaining a digest; decrypting the digest, to obtain a storage index table; verifying validity of a private-key signature of the deposit transaction; downloading transaction data of the deposit transaction according to a data index; decrypting the transaction data; and verifying validity, legitimacy, and integrity of the decrypted transaction data. A data source of electronic contract forensics is ensured by querying the deposit information and the corresponding deposit transaction, and credibility of electronic contract forensics is ensured by verifying the validity, the legitimacy, and the integrity of the transaction data, thereby achieving an electronic contract forensics process.
