Abstract
Systems and methods are described for managing digital rights. Methods may comprise causing an encrypted content asset to be stored at a storage location. The encrypted content asset at the storage location may be accessible by one or more user devices. A transaction may be generated and may comprise an identifier and a decryption key, wherein the decryption key is configured to decrypt at least a portion of the encrypted content asset. The transaction may be caused to be stored in a distributed database, wherein the distributed database is accessible by the one or more user devices using at least the identifier.

Abstract
A blockchain-based infringement detection method includes: receiving a registration transaction initiated by a user, wherein the registration transaction includes key data of a work to be deposited and a contract address of a smart contract; invoking, in response to the registration transaction, a first detection logic declared in the smart contract corresponding to the contract address, extracting a feature value from work content of the work to be deposited, and matching the extracted feature value with a feature value of a deposited work in the blockchain; if the matching succeeds, further invoking a second detection logic declared in the smart contract corresponding to the contract address, matching the key data of the work to be deposited with key data of the deposited work in the blockchain, and when the matching succeeds, determining that the work to be deposited has an infringement risk.
