Problems solved by technology

[0002] Usually, employers have the need to check the authenticity of applicants' education, degree, professional certificate and other certificates when recruiting. The traditional offline certificate query has the problems of complicated process and low efficiency. If the online query is provided by the certificate granting institution service, the security requirements for the certificate file management database of the certificate-granting organization are very high, and it is difficult to provide online certificate query services to the public under the premise that each certificate-granting organization guarantees security with the current technology

Embodiment 1

[0021] The embodiment of the present invention provides a method for building a certificate storage and query blockchain, which can be applied to the storage and query of certificates such as academic certificates, degree certificates, vocational qualification certificates, title certificates, identification certificates, etc., certificate storage and query blockchain The construction methods include:

[0022] Step 101: Build a certificate query blockchain, where the certificate query blockchain includes a request node and a service node. The request node is used to receive a certificate query request. There are multiple service nodes, and each service node corresponds to a certificate-granting institution. , The service node includes a first child node and a second child node. The first child node is located in the certificate query blockchain and is used to obtain the certificate query request sent by the requesting node.

[0023] In this embodiment, constructing a certificate qu...

Embodiment 2

[0040] This embodiment provides a construction device for certificate storage and query blockchain, which includes a first construction unit and a second construction unit.

[0041] The first construction unit 21 is used to construct a certificate query blockchain. Among them, the certificate query blockchain includes a request node and a service node. The request node is used to receive a certificate query request. There are multiple service nodes. Each service node corresponds to a certificate-granting institution. The service node includes a first child node and a first child node. Two child nodes, the first child node is located in the certificate query blockchain and is used to obtain the certificate query request sent by the requesting node.

[0042] The second construction unit 22 is used to construct a certificate storage blockchain. Among them, a certificate-granting institution corresponds to a certificate storage blockchain, where the first construction unit 21 is conne...

Embodiment 3

[0044] This embodiment provides a certificate storage and query blockchain system. The system constructed by using the certificate storage and query blockchain construction method of Embodiment 1 includes: a certificate query blockchain and a certificate storage blockchain.

[0045] The certificate query blockchain includes a request node and a service node. The request node is used to receive certificate query requests. There are multiple service nodes. Each service node corresponds to a certificate-granting institution. The service node includes a first child node and a second child node. Node, the first child node is located in the certificate query blockchain, and is used to obtain the certificate query request sent by the requesting node.

[0046] The certificate storage blockchain is used to find the corresponding certificate in the certificate storage blockchain according to the certificate query request, where a certificate-granting authority corresponds to a certificate sto...

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 ...
