The invention discloses an electronic evidence auditing method and device based on a block chain and a storage medium. The method comprises the steps of obtaining the electronic evidence; combining the original relational database with the block chain; establishing a distributed file system based on a block chain, and carrying out fragmentized storage on the electronic evidence; constructing an audit pool according to an encrypted log, and auditing the operation behavior of the audit pool, the encrypted log at least comprising a data log and a consensus log; establishing a consensus pool; andbased on a consensus mechanism, obtaining and synchronously updating the electronic evidence in each block chain node in the distributed file system. Through the mode, the difficulty of tampering electronic evidences by the network nodes can be improved, the tampering behavior cannot be repudiated, and the problems that the electronic evidences are tampered easily and the tampering behavior cannotbe traced are solved.
Description
technical field [0001] The invention relates to the field of block chains, in particular to a block chain-based electronic evidence auditing method. Background technique [0002] In the face of increasingly rampant hacking activities, it is imperative to ensure data security. Traditional database technology is facing the increasingly serious challenges of data tampering and other security incidents. Especially the user's purchase records on the e-commerce platform and chat records with e-commerce customer service. Since these records are all recorded on the e-commerce platform, the stored purchase records and chat records are easy to be lost or maliciously deleted, or even deleted. Malicious tampering. When a transaction dispute occurs, it is difficult for users to provide evidence. [0003] It can be seen that traditional database technology cannot prevent tampering, nor can it trace tampering behaviors, making it difficult to ensure data security. Contents of the inve...
