File attesting method and device, file verification method and device and file proof method and device

Abstract

The invention discloses a file attesting method and device, a file verification method and device and a file proof method and device. The file attesting method comprises the following steps of: receiving a file attesting request, aiming at a to-be-attested file, sent by a user side; storing corresponding file data to a block chain according to the file attesting request and generating file attesting information; synchronizing the file attesting information to a judicial proof mechanism node on the block chain; and receiving feedback information sent by the judicial proof mechanism node and sending the feedback information to the user side. According to the file attesting method and device, the file verification method and device and the file proof method and device, the judicial proof mechanism node is imported into the block chain for attesting files, and block chain storage process of digital information such as electronic evidences and the like is filed and supervised through the judicial proof mechanism node, so that the problem that the prior art is relatively low in credibility in the aspects of data preservation and attesting of digital information is solved.

Description

technical field [0001] The invention relates to the technical field of digital information processing, in particular to a method and device for document storage, authenticity verification and proof production. Background technique [0002] With the continuous development of Internet finance, people's requirements for the security and reliability of Internet transaction information continue to increase. Generally speaking, we can start from two aspects to realize the transaction security and integrity management of Internet finance. On the one hand, management means can be used to solve the security defects of Internet finance; on the other hand, some technical means can be adopted to avoid the hidden dangers of Internet finance. Data preservation and certificate storage technology are one of the important technical means. In the existing technology, when electronic evidence is fixed, the binding and curing of electronic evidence snapshot files can be realized through the bl...
