Blockchain-based digital content forensics method, device and equipment

Abstract

Embodiments of this specification provide a blockchain-based digital content forensics method, device, and equipment. In the blockchain-based digital content forensics method, the first node receives a digital content forensics task. A plurality of second nodes are selected from the plurality of nodes, and an execution instruction of the forensics task is sent to each second node in the plurality of second nodes. A plurality of forensic results returned by each second node after performing a corresponding forensic task is received. Determine whether multiple forensic results match. If they match, any first forensic result is selected from the plurality of forensic results as the evidence deposit result. Store the certificate storage result locally, and broadcast the certificate storage result to other nodes except the first node among the multiple nodes, so that other nodes store the certificate storage result after consensus verification.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular to a blockchain-based digital content forensics method, device, and equipment. Background technique [0002] In the current field of digital copyright protection, the phenomenon of piracy of digital content such as pictures and videos often occurs. The main reasons are the following two aspects: First, there are very few preservation agencies that can protect the copyright of digital content, and the processing steps are cumbersome, and the evidence collection method is single, which cannot provide extensive and convenient copyright protection services for all sectors of society. Second, there are many non-standard, non-standard, and unsafe factors in the user's self-collection of evidence, which may easily lead to the failure to appeal the original legitimate rights. Therefore, how to effectively obtain evidence on digital content becomes a pro...
