Design of an Intellectual Property Rights Certification System Based on a Consortium Blockchain

Under the background of economic globalization and the rapid development of the knowledge economy, a large number of intellectual property achievements in China need to flow efficiently in order to give full play to their value; however, the traditional method of rights confirmation has problems, such as complicated operation, low efficiency, high cost, etc., and its practicability is limited. For this reason, this paper aims to construct an efficient intellectual property rights confirmation system by utilizing the characteristics of non-repudiation, non-tampering, traceability and distribution of the consortium chain. By designing smart contracts for user login and registration, rights confirmation, and transaction; combining with the Chameleon Signature algorithm to guarantee transaction security; and ensuring integration with the IPFS to improve the efficiency of file storage, this research develops an IPR confirmation system based on the consortium chain. This system was ultimately successfully deployed and tested, verifying that it operates with good efficiency and correctly realizes the expected functions. The findings show that the proposed system can effectively simplify the operation, provide reliable credentials, guarantee security and storage efficiency, and provide a feasible solution for intellectual property rights.
