Electronic evidence storage system based on block chain

Abstract

The invention provides an electronic evidence storage system based on a blockchain, and the system comprises: an information fingerprint collection module which collects a hash value of user evidencestorage data, enables the hash value to be hash1, enables the hash value to be hash2 after a timestamp is added, enables the collected data and original data to be stored together, and enables the timestamp and the hash2 to be transferred to a next module; a data linearization packaging module which carries out hash calculation on a timestamp and hash 2 which are finally transferred by the information fingerprint acquisition module, generates a chain type data structure, wherein the chain type structure is linearized based on a time axis, and a data chain is irreversible; a blockchain system interacting module which submits transaction information to the blockchain, checks and confirms a transaction state, and stores a transaction record in a warehouse; and a database which is used for centralizing the database and reading, writing and storing data contents of other modules. Complex electronic data is evidenced, high effectiveness of evidences is guaranteed, user cost is reduced, userevidence providing efficiency is improved, case handling efficiency of judicial organs is improved, and powerful support is provided for digital economy.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates 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...

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
