Abstract

The invention discloses an audio and video evidence preservation method and system. The method comprises the following steps: verifying an audio and video original file uploaded by a mobile terminal;when the verification passes, generating a complete data fingerprint of the audio and video original file, sending a storage address of the audio and video original file, user information corresponding to the audio and video original file and the complete data fingerprint to a block chain network, and updating storage contents in an authoritative certification node. By adoption of the method, theformation time of the audio and video files and the instantaneity, directness, authenticity, reliability and storage security of recorded contents can be proved, therefore the audio and videos recorded by mobile terminals become credible judicial evidence.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to an audio and video evidence preservation method and system. Background technique [0002] With the rapid development of computer technology, information technology, Internet technology, and communication technology, the preservation and production of evidence of electronic data has received more and more attention from the parties and the judiciary. However, due to its easy tampering and forgery, electronic evidence is difficult to be accepted and recognized by the court. However, many electronic evidences are important clues to restore the truth. The lack of such evidence will easily lead to the failure of the right holders to obtain their legitimate rights. legal protection. [0003] Audio and video files used as judicial evidence must ensure their authenticity, reliability, and non-tampering, so that they have the function of proof. Existing recordin...
