Block chain-based credible issuing, calling and use methods for electronic license

Abstract

The invention relates to block chain-based credible issuing, calling and use methods for an electronic license. The block chain-based credible use method for the electronic license comprises the following steps that an issuing party generates the to-be-issued electronic license according to specifications, and stores the to-be-issued electronic license in a server of the electronic license; the issuing party generates abstract information of electronic license issuing according to the specifications, and writes the abstract information into a block chain; the issuing party provides a service interface for obtaining detailed information of the electronic license; a calling party views the detailed information of the issued electronic license through the service interface provided by the issuing party; the calling party obtains the issuing abstract information corresponding to the detailed information of the electronic license in the block chain; and the calling party verifies the consistency between the detailed information of the electronic license and the abstract information of the license. The block chain-based credible use method for the electronic license has the advantages that centralized storage of electronic licenses can be avoided, and meanwhile, the reliability of the electronic license is guaranteed.
