Description
Technical Field
The invention relates to the field of block chain evidence storage application, in particular to a block chain evidence storage method and a block chain evidence storage system.
Background
The common evidence is that electronic data (such as electronic contract, webpage, photo, video, audio and video, electronic document, call record, e-mail and the like) is stored in a backup form on a self organization or a leased server, and because the electronic data is very easy to be damaged, faults such as flaws, breakpoints, incomplete evidence and the like are easily caused in the transmission process. Not only is there a high technical demand from third-party certificate authority, but also the number of transfers and hands-backs is reduced in the electronic data generation, solidification, certificate storage, storage and subsequent evidence use, and if the electronic data is stored on a leased server, the number of data transfers is necessarily increased, the risk of data tampering is increased, and the integrity is also destroyed. Furthermore, the third-party certificate authority is also an enterprise, and various unexpected situations such as unstable service are likely to occur.
With the rapid development of the blockchain technology, evidence storage services based on the blockchain technology are widely applied to various industries. The block chain evidence storage is based on a block chain technology, and adopts a multi-node common identification mode or combines electronic data evidence storage services of authoritative mechanism nodes such as a court, a notarization department, an arbitration mechanism, a judicial appraisal center, a time service mechanism, an auditing mechanism, a digital identity authentication center and the like.
The block chain evidence storing business can be accessed to third-party institutions such as an internet court, a judicial appraisal center, an international time service center trusted time service center, a CA authentication center and the like, so that the authority, reliability and authenticity of electronic data evidence storage are guaranteed. The 'regulations' issued in 2018 by the highest court in China mention that 'the authenticity of electronic data submitted by a party can be proved through the technical means of evidence collection, fixation and tamper resistance such as electronic signatures, credible timestamps, hash value verification, block chains and the like or through the authentication of an electronic evidence obtaining and storing platform, and the internet court should be confirmed'. The method is that the law confirmation is carried out on the evidence-based evidence-storing means such as the credible timestamp and the block chain in the judicial explanation form for the first time in China, means that the application of the electronic evidence-storing technology in the judicial level is a significant breakthrough, and simultaneously shows that the block chain evidence-storing application service has good market prospect.
In the current block chain evidence storage technology, a large amount of paid CA authentication service is usually adopted as a corresponding element of an evidence storage person, but because the CA authentication service provided by the current CA authentication center is charged and the evidence storage cost of a user is high, a method capable of replacing the CA authentication service as one of key elements of the block chain evidence storage is urgently needed to be provided.
