Copyright authorization management method and system

Embodiments of the present disclosure disclose a copyright authorization management method and system. The method includes: obtaining owner-of-copyright information; sending a contract determining notification to a corresponding owner-of-copyright client based on the owner-of-copyright information, where the contract determining notification carries copyright-related information of a to-be-authorized work; receiving transaction information returned by the owner-of-copyright client, where the transaction information includes contract information determined by an owner of copyright based on the copyright-related information; obtaining a valid contract transaction based on the transaction information, where the valid contract transaction includes signatures satisfying a preset-quantity rule; and implementing persistence of the valid contract transaction in a block chain. In technical solutions provided in the embodiments of the present disclosure, online contract signing and persistence of a signed contract are implemented based on the block chain. This improves copyright authorization efficiency, and ensures that the contract is unique, trustworthy, and unalterable.
