A blockchain-based license management method

Abstract

The invention provides a blockchain-based certificate management method, including: the attribute provider registers on the certificate chain, and creates a user's attribute identity information template on the certificate chain; completes the creation of the attribute identity information template and pushes it to the certificate chain The user's attribute identity information and corresponding electronic certificate information are calculated and uploaded to the chain; the user registers the basic identity through the relying party, and logs in to the relying party after completing the basic identity registration, and then binds the attribute identity on the certificate chain according to the attribute identity information template information, after binding the attribute identity information, the user can view the corresponding electronic certificate information stored on the certificate chain through the relying party; at the same time, after viewing the electronic certificate information, the user can selectively present, update and remove. The invention establishes an electronic license information supervision mechanism based on block chain technology, and realizes the supervision of electronic license information sharing behavior and content.
