Certificate storage and query block chain construction method, device and system and query method

Abstract

The invention provides a certificate storage and query block chain construction method comprising the steps that a certificate query block chain is constructed, the certificate query block chain comprises a request node and a service node, the service node comprises a first sub-node and a second sub-node, and the first sub-node is located in the certificate query block chain and used for obtaininga certificate query request sent by the request node; and a certificate storage block chain is constructed, one certificate granting mechanism corresponds to one certificate storage block chain, thesecond child node is located in the certificate storage block chain, and the second child node is connected with the first child node by setting a firewall and is used for searching a corresponding certificate in the certificate storage block chain according to the certificate query request. Correspondingly, the invention further provides a construction device, a construction system and a certificate query method based on the certificate storage and query block chain system. Certificates can be safely stored by a certificate granting institution, and the authenticity of job seeker certificatescan be conveniently inquired on line by an employee unit.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for building a certificate storage and query blockchain, a building device, a certificate storage and query blockchain system, and a certificate query method. Background technique [0002] Generally, employers have the need to inquire about the authenticity of applicants’ academic qualifications, degrees, vocational certificates and other certificates when recruiting. Traditional offline certificate inquiries have complicated processes and low efficiency. However, if the certification institution provides online inquiries Service, the security requirements for the certificate file management library of the certificate-issuing institution are very high. With current technology, it is difficult to realize the security of each certificate-issuing institution to provide online certificate query services to the public. Summary of the invention [0003] The technical ...
