Electronic evidence storage system based on block chain

Abstract

The invention provides an electronic evidence storage system based on a block chain. The system comprises an electronic evidence system which comprises an information fingerprint acquisition module, adata linearization packaging module, a block chain system interaction module and a database. The information fingerprint acquisition module is used for acquiring an original file hash value of electronic evidence storage data of a user, recording the original file hash value as a first hash value, recording a target hash value added with a timestamp as a second hash value, storing the acquired data and the original data into a database together, and transferring the timestamp and the second hash value to the data linear packaging module; the data linearization packaging module is used for performing hash calculation on the timestamp transferred from the information fingerprint acquisition module and the second hash value to generate a chain type data structure, and sending the chain typedata structure to the blockchain system interaction module; and the block chain system interaction module is used for packaging the chain data, submitting the packaged chain data to a block chain, checking and confirming a transaction state, and recording a transaction record into a database.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to an electronic certificate storage system based on block chains. Background technique [0002] With the rapid development of information construction, electronic data has become an important form of expression, and in some occasions, it may be the only form of expression. The advent of the Internet has brought a lot of convenience, but also brought a lot of infringements. Many legal disputes are presented in the form of electronic data. Electronic data has the characteristics of high technology, various forms, accuracy and easy transmission. Electronic data It plays an important role in the case, but electronic data also has some disadvantages, such as easy misoperation, easy to be affected by hardware failure, etc., easy to be tampered with and destroyed, which has an impact on the credibility of electronic data, and In the law, there are no detailed regulations on electron...

The advent of the Internet has brought a lot of convenience, but also brought a lot of infringements. Many legal disputes are presented in the form of electronic data. Electronic data has the characteristics of high technology, various forms, accuracy and easy transmission. Electronic data It plays an important role in the case, but electronic data also has some disadvantages, such as easy misoperation, easy to be affected by hardware failure, etc., easy to be tampered with and destroyed, which has an impact on the credibility of electronic data, and In the law, there are no detailed regulations on electronic data. Therefore, how to use electronic evidence correctly and safely, and use electronic evidence to protect rights has always been a difficult problem
