Digital content evidence obtaining method, device and apparatus based on block chain

Abstract

The embodiment of the invention provides a digital content evidence obtaining method, device and apparatus based on a block chain. The digital content evidence obtaining method based on the block chain comprises the steps of receiving an evidence obtaining task of digital content by a first node; selecting a plurality of second nodes from the plurality of nodes, and sending an execution instruction of the evidence obtaining task to each second node in the plurality of second nodes; receiving a plurality of evidence obtaining results returned by the second nodes after the second nodes execute the corresponding evidence obtaining tasks; judging whether the plurality of evidence obtaining results are matched or not; if the plurality of evidence obtaining results are matched, selecting any first evidence obtaining result from the plurality of evidence obtaining results as an evidence storage result; storing the evidence storage result locally, and broadcasting the evidence storage result to other nodes except the first node in the plurality of nodes, so that the other nodes perform consensus verification on the evidence storage result and then store the evidence storage result.

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...
