The invention discloses a method for using a digital certificate based on a block chain, comprising: the business background receives an application for using a digital certificate initiated by a client, and receives the biometric information of the applicant submitted by the client; Biometric information for identity authentication; when the identity authentication is passed, confirm that the client has obtained the authority to use the digital certificate, and call the certificate service system to apply for a digital certificate from a third-party organization, so that the certificate service system can use the digital certificate to provide the client with Digital signature or encryption service, in which electronic evidence related to the application and use of digital certificates is stored through the blockchain storage system. The invention also discloses a service processing system and a computer-readable storage medium. The invention improves the safety and convenience of using the digital certificate, and also saves the issuing cost and the using cost of the certificate.
Description
technical field [0001] The present invention relates to the technical field of digital certificates, in particular to a blockchain-based digital certificate usage method, a business processing system and a computer-readable storage medium. Background technique [0002] The use of existing digital certificates mainly adopts the following two methods: one is to use the USB shield, and the other is to install and use digital certificates. The specific implementation methods are as follows: [0003] Option 1: The user first applies for a USB-Shield from the relevant organization, and then uses the USB-Shield installed with a digital certificate to log in, sign and encrypt to complete business operations; [0004] Solution 2: The user first applies for a digital certificate from the relevant organization, and then installs the digital certificate into the operating system; the user uses the pre-installed digital certificate in the system to log in, sign and encrypt to complete bu...
