ELECTRONIC CERTIFICATE CIRCULATION MANAGEMENT METHOD AND SYSTEM BASED ON BLOCKCHAIN, AND BLOCKCHAIN PLATFORM
Document Type and Number:
WIPO Patent Application WO/2022/021009
Kind Code:
A1
Abstract:
An electronic certificate circulation management method based on a blockchain. The method comprises the following steps: generating an electronic certificate T, and encrypting key identification information of the electronic certificate T by using a key K (S01); embedding a result of the encrypted electronic certificate T into a blockchain token Z, wherein the blockchain token Z is the unique mapping of the electronic certificate T on a blockchain (S02); and taking the blockchain token Z as a basic object and performing one or more operations from among issuing, selling, exchanging and writing-off (S03). By means of the present method, an electronic certificate is encrypted and then embedded into a blockchain token, and a blockchain is used as a basic accounting means and an accounting auditing tool, such that a secure and reliable connection between an issuer of the electronic certificate and a user of the electronic certificate is established, thereby ensuring the efficient and secure use and management of the electronic certificate.
