Abstract

The invention relates to the technical field of block chain application. The invention discloses a block chain digital watermark-based digital resource infringement tracking method and system, and themethod comprises the steps: packaging digital resource uploading, transaction and distribution information into a block, and recording the block in a block chain according to a time sequence, and comprises the steps: generating a block on the block chain when a user uploads digital resources, and recording copyright information; when the copyright of the digital resource is transferred, a block is generated on the block chain, and corresponding transaction information is recorded; when the digital resources are distributed, a block is generated on the block chain, corresponding distribution information is recorded, and a digital watermark is embedded into the digital resource entity; when infringement copying of digital resources occurs on the market, infringement tracking is carried outby combining the digital watermarks in the infringement copying of the digital resources with the transaction records of the digital resources on the block chain system. According to the method, the digital watermark is combined with the block chain, so that the digital watermark information can not be tampered with a chain, and infringement tracking information is guaranteed to be real and credible.

Description

technical field [0001] The present invention relates to the technical field of blockchain applications, in particular to a digital resource infringement tracking method and system based on blockchain digital watermarks. Background technique [0002] With the development of the Internet, the creation and dissemination of digital resources have become increasingly frequent. In recent years, infringements of digital resources have been common and difficult to be held accountable. The reasons include: using the resources provided by various download platforms on the Internet, high-speed and convenient downloads can be performed, which creates convenient conditions for the piracy of digital resources; The cost of dissemination on the Internet is low, and the supervision of copyright has created certain difficulties; digital resources need to be authorized by the China Copyright Protection Center in order to obtain copyright protection, which will generate a lot of time costs, and...
