DETECTION METHOD, DEVICE AND SYSTEM FOR COPYRIGHT PROTECTION

A method, an apparatus, and a system for copyright rights defense detection are provided. The method includes: sending a metadata query request to a copyright handling apparatus; receiving a metadata query response that is sent by the copyright handling apparatus and that includes feature metadata, where the feature metadata is obtained by the copyright handling apparatus based on a detection task transaction identifier from a blockchain stored in a blockchain processing apparatus; obtaining a rights-to-be-defended content feature corresponding to the feature metadata from a feature database; sending a license query request to a license processing apparatus; receiving a license query response that is sent by the license processing apparatus and that includes license information, where the license information is obtained by the license processing apparatus based on the detection task transaction identifier from a blockchain stored in a blockchain processing apparatus; and performing rights defense detection for a copyright based on the obtained rights-to-be-defended content feature and the license information. Rights defense detection can be performed for a copyright by any rights defense detection service apparatus.
