Electronic evidence preservation system based on block chain subliminal channel technology

Abstract

The invention discloses an electronic evidence preservation system based on a block chain subliminal channel technology, which comprises a client, a server, an auditing terminal and a network terminal, and is characterized in that the client is used for performing off-line acquisition and processing, online management and evidence collection on a user electronic evidence; the server generates an existence proof for the evidence and performs hosting and recovery on the chain evidence according to a user address; the auditing terminal is used for auditing the chain evidence, generating a corresponding transaction on a block chain and constructing an auditing proof so as to main the integrity, the timeliness and the non-repudiation of an auditing result; and the network terminal is used for performing state synchronization and real-time evidence collection on the user evidence on the chain. The system can dig a cryptographic basis of the subliminal channel preserved electronic evidence and the auditing result thereof in a mature block chain system, thereby realizing safe processing and hidden preservation for the electronic evidence, thus improving the safety and timeliness of electronic evidence preservation, and effectively reducing the preservation cost.

Description

technical field [0001] The invention relates to the field of telecommunications information technology, in particular to an electronic evidence preservation system based on block chain latent channel technology. Background technique [0002] With the development of information technology and the popularization of computer networks, electronic evidence, as a derivative of a large number of electronic business activities and network communication activities, has played a role in the collection of evidence and related department management in copyright protection, commercial rights protection, virtual property, mobile office, etc. playing an increasingly important role. Among them, the main feature of electronic evidence is that it is attached to digital media, and has the convenience of rapid collection, convenient transmission, small storage space, and repeatability, so that electronic evidence can play an important role in future rights protection and law enforcement. Can b...
