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.
