b. And the teacher verifies the honor of the students according to the actual condition. If the audit is passed, the following c-e are executed.
c. A digital digest of the electronic version of the proof of record material is computed using a digest algorithm (e.g., SHA256, SM3) as the Key value stored for the blockchain.
d. The digital digest is signed with a private key corresponding to the identity of the higher school using a signature algorithm (e.g., RSA, SM2) as a Value stored for the blockchain.
e. And submitting the digital abstract and the digital signature obtained by calculation to a history storage module of the block chain system for storage.
The student audit is used as supplement of the teacher audit link to form a decentralized audit system, and the specific process comprises the following steps:
a. history providers (schools, students) disclose reputation information to students within a predetermined range or randomly.
b. Students (auditors) perform historical audits. And c-e is executed if the examination is passed, otherwise, the examination system uploads information to the administrator system, and the teacher performs re-examination.
c. A digital digest of the electronic version of the proof of record material is computed using a digest algorithm (e.g., SHA256, SM3) as the Key value stored for the blockchain.
d. The digital digest is signed with a private key corresponding to the identity of the higher school using a signature algorithm (e.g., RSA, SM2) as a Value stored for the blockchain.
e. And submitting the digital abstract and the digital signature obtained by calculation to a history storage module of the block chain system for storage.
After the resume materials are submitted, the digital signatures of different types and different quantities can be retained in the block chain system through the process of auditing by three parties, namely a school, a teacher and students. Specifically, the method comprises the following steps:
for the curriculum vitae data generated in the school, the decision weight ratio of the school, the teacher and the student is 5: 1: 4; the school weight ratio of 50% means that the historical material is invalid if the school denies the authenticity of the historical material.
For curriculum vitae data generated outside the school, the school does not participate in authenticity decision, and the decision weight ratio of teachers and students is 4: 6, this means that when the teacher's audit is incorrect, the students can invalidate it by means of collective voting.
The decision weights are different when all students vote for authenticity. As the correct decisions for student participation increase, the weights increase. Further, the reviewer specified by the history provider may be weighted less than the randomly selected reviewer.
When the comprehensive evaluation truth of the audit result of the resume material is less than 50%, the resume material is regarded as invalid; between 50% and 95%, will be reexamined by the reviewer; if the authenticity is more than 95%, the certificate is regarded as being authentic, and an authenticity certificate can be issued (considering that the anonymous reviewer does not pass maliciously, the authenticity is regarded as being more than 95%).
And S4, after receiving the electronic edition resume material, the enterprise client calculates the digital abstract of the electronic edition resume material by using an abstract algorithm and sends the digital abstract to the block chain information verification module, and the block chain information verification module searches the corresponding storage record according to the digital abstract and obtains the audit record of the resume material, and verifies the authenticity of the digital signature by using a signature verification algorithm. The method specifically comprises the following steps:
a. the students sort and pack the resume materials of the digital edition and send the resume materials to the enterprises applying for hiring;
b. acquiring digital resume materials by an enterprise recruitment principal and uploading the digital resume materials to a system;
c. the system calculates a digital digest of the electronic version of the biographical certification material using a digest algorithm (e.g., SHA256, SM3) and submits the digital digest to a certification module on the blockchain;
d. the block chain certification module inquires corresponding storage records according to the digital abstract, obtains audit records of the resume materials, and verifies the authenticity of the digital signature submitted by each auditor by using a signature verification method (such as RSA, SM 2);
e. the block chain proving module calculates the authenticity of the resume material according to the audit record and the proving mechanism in the step 3.3, and if the authenticity exceeds 90 percent, the block chain proving module provides an authenticity proving;
f. the authenticity certificate comprises an authenticity score and auditor information (in order to protect the auditor information, the name of the auditor cannot be displayed in a clear text, and only rough information such as the class of the auditor is displayed);
g. and the enterprise terminal judges the authenticity of the student record according to the interview result and the verification result. The decision weight of all reviewers is affected by the decision result.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.

performing user identity authentication including college identity authentication, teacher-student identity authentication and enterprise identity authentication based on certification materials submitted by users, and allocating unique distributed ID (identity) to the authenticated users;
storing historical data submitted by a user, wherein the historical data comprises a Key Value which is stored in a block chain and is obtained by using an abstract algorithm to extract a digital abstract, a Value which is stored in the block chain and is obtained by using a signature algorithm to sign the digital abstract, and then the obtained digital abstract and the obtained digital signature are stored in the block chain system;
after the resume data is submitted, obtaining the auditing results of the school, the teacher and the students, and obtaining the comprehensive judging truth of the auditing results based on the preset decision weight;
and the enterprise client calculates the digital abstract of the electronic-version resume material by using an abstract algorithm after receiving the electronic-version resume material, and sends the digital abstract to the block chain information verification module, and the block chain information verification module searches the corresponding storage record according to the digital abstract and obtains the audit record of the resume material, and verifies the authenticity of the digital signature by using a signature verification algorithm.
