Description

Blockchain-based copyright management method and device {METHOD AND APPARATUS FOR BLOCKCHAIN-BASED COPYRIGHT MANAGEMENT}

The present invention relates to a blockchain-based copyright management technology, and more particularly, to a blockchain-based copyright management that provides copyright tracking of video media uploaded to a video hosting service and copyright transfer contract and tracking between users using a blockchain. It relates to methods and devices.

A conventional video hosting service solves copyright issues by conducting a complete enumeration by comparing an image uploaded by a user to each server with all previously registered images of others, or by filing an objection with the original copyright holder.

This requires a high amount of computation on the side of the service provider, and the user must prove the actual production and exclusive right to the work in order to object. It is difficult for small content producers who have difficulty in self-evidence to receive protection for their intellectual property. In addition, since the service does not support the transfer of copyrighted works to other service users or copyrighted works, it is difficult to guarantee the reuse of copyrighted works through an intellectual property license agreement.

The conventional blockchain requires access to the blockchain through a blockchain client application, and because the process is complicated, accessibility is low and there is a sense of rejection from the user's point of view.

However, the solution to the copyright management problem through the conventional block chain traces the original video through the smart contract of Ethereum. However, all video information in the tracking process must be registered on the platform, and matching information is checked only through video metadata.

To this end, the copyright self-cleaning unit 330 may perform a flag, which is a censorship function for copyright protection and violation tracking through self-cleaning between user terminals. The flag may be a process for resolving an objection against copyright infringement content by an unspecified user for registered media content.

Depending on the embodiment, the user terminal in the private blockchain network 200 may raise more questions about media content with high revenue and topicality according to the Crab Mentality theory.

The copyright self-remediation unit 330 may select a random voting group based on a random number generated corresponding to the flagged media content and user reputation information. The voting group may refer to the media content information stored in the private blockchain network 200 and the details of the transfer agreement to vote on whether or not the copyright is infringed on the suspected content.

Therefore, when a user terminal within the blockchain network 200 raises a problem, the copyright self-remediation unit 330 selects a random user for the raised problem through a mutually unreliable random number generator and user reputation value to perform a vote can do. The block chain-based copyright management method can perform positive voting in the forward direction through a designated compensation policy and reputation policy.

Depending on the embodiment, the copyright self-remediation unit 330 may determine infringement by referring to the copyright policy and the interactive copyright transfer contract recorded in the ledger. Voting holders can cast correct positive (+) votes through compensation policy and reputation policy. At this time, each voting right has a voting weight and can be weighted by a reputation index.
