Abstract

The invention discloses an electronic license directional use management method and device, electronic equipment and a storage medium. The method comprises the steps of receiving a query license acquisition request initiated by a local government affair platform; verifying the acquisition request, and generating an electronic license query license after the verification is passed; sending the electronic license query license to the local government affair platform, so that the local government affair platform carries out uplink on the query record, receives a hash value generated after uplink, and initiates an electronic license query accreditation request to a license library system, where the request carries the electronic license query license and the hash value; and sending the electronic license query license to the license library system, so that the license library system verifies the electronic license query license and the hash value sent by the local government affair platform according to the electronic license query license sent by the license issuing unit system; and after the verification is passed, stamping a watermark on the to-be-queried electronic license, and sending the electronic certificate covered with the watermark to a local government affair platform.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a method and device for managing the directional use of electronic certificates, electronic equipment, and storage media. Background technique [0002] At present, most blockchain-based electronic license systems have made many innovations in the application, issuance, sharing, and verification of licenses. For example, the issuance of electronic certificates is realized by uploading the structured information in the electronic certificates to the chain; the point-to-point sharing of electronic certificates is realized by using asymmetric encryption technology; the uniqueness is confirmed by using the hash value stored on the blockchain, etc. There have been many innovative methods for the issuance and generation of electronic certificates. The issuance of electronic certificates based on blockchain can effectively guarantee the uniqueness and accuracy of certifi...
