Step 302, academic information is verified, after being verified, academic information is stored and is based on educational background letter
Breath the first identification code of generation, user is sent to by the first identification code；Wherein, the first identification code is uniquely corresponding with academic information；
User is inputted in inputting interface after the academic information of individual, and academic Verification System needs to user's input
Go through information to be verified, to ensure the authenticity of academic information from source.
Specifically, academic Verification System can carry out network with the system platform for the academic certification authority for issuing academic certificate
Connection, and the academic information received is sent to the system platform of academic certification authority, academic certification authority can verify
Go through the true and false of information.
If academic certification authority verifies that academic information is real, feedback message, checking are sent to academic Verification System
Message includes the result that academic Information Authentication passes through；Academic Verification System is according to for representing what academic Information Authentication passed through
Feedback message, by the storage of academic information in the local database, while the first identification code, academic certification are generated according to academic information
First identification code can be sent to user by system simultaneously.
Specifically, academic Verification System carries out Hash operation to academic information, the first identification code is generated, wherein, the first mark
It is uniquely corresponding with academic information to know code.
Step 303, the first public key that user sends is received, and the encryption message sent according to the first public key to user is carried out
Decryption, encryption message is generated after the first identification code is encrypted using private key for user by user；
After first identification code is sent to user by academic Verification System, the encryption message of user feedback can be continued to,
It can be generated after the first identification code is encrypted using private key for user by user to encrypt message.Wherein, private key for user can be with
For the first private key.Meanwhile the first public key is sent to academic Verification System by user, academic Verification System is added using the first public key pair
Close message is decrypted.Wherein, the first public key and the first private key are generated by asymmetric encryption, the first public key and the first private
Key has unique corresponding relation.
Step 304, judge whether the first public key encryption message can be decrypted；
Because encryption message is generated after the first identification code is encrypted using private key for user by user, the different user palm
The private key for user held is unique and mutually different, but only rests in educational background and recognize with unique corresponding first private key of the first public key
Card system is sent in user's hand of academic information.Therefore the use of encryption message and academic information is only sent to academic Verification System
When family is same user, just generation encryption information, Jin Er can be encrypted to the first identification code using the first private key in user
Just encryption message can be decrypted for one public key.
If the user for sending encryption message and academic information is different user, sending the user of encryption message will not use
First identification code is encrypted first private key, and then academic Verification System can not just be carried out using the first public key to encryption message
Decryption.
If the result of step 305, step 304 is yes, it is determined that private key for user is the first private key corresponding with the first public key,
And obtain decrypted result；
If encryption message can be decrypted for the first public key, decrypted result corresponding to academic Verification System acquisition.
If the first public key can to encryption message be decrypted, it is determined that to academic Verification System send encryption message and
The user of academic information is same user, and private key for user is the first private key corresponding with the first public key, and then demonstrates user
The legitimacy of identity, academic Verification System is prevented to be sent to the first identification code and inconsistent its of the user that sends academic information by mistake
He is user.It is also possible to prevent the other users inconsistent with the user of the academic information of transmission from intercepting and capturing academic Verification System and sending out
The first identification code for sending and the problem of cause individual subscriber privacy leakage, improve the reliability of academic verification process.
Step 306, judge whether decrypted result is consistent with the first identification code；
Because encryption message is to be sent to academic certification system after the first identification code is encrypted using the first private key by user
System, thus while the user to academic Verification System transmission encryption message and academic information is same user, but user is sending out
Sending may be modified before encryption message to the first identification code, or the number of the first identification code caused by other odjective causes
According to damage, and cause academic authentication result inaccurate.
In order to avoid above mentioned problem occurs, academic Verification System may further determine that and be sent in step 302 to user
The first identification code and step 303 in decrypted result corresponding to the encryption message fed back to academic Verification System of same user be
It is no consistent, to judge whether user is modified to the first identification code or whether the first identification code generates corrupted data, from
And the data integrity of the first identification code is ensure that, further improve the reliability of academic verification process.
If the result of step 307, step 306 is yes, receives user and identified using the first private key to first at code encryption
The 3rd identification code after reason, and the 3rd identification code is encrypted using the second private key of itself, generate the 4th identification code
With checking message；
If decrypted result is consistent with the first identification code, then it represents that user is receiving the first mark of academic Verification System transmission
After knowing code, it make use of the first private key that the first identification code is encrypted and generate encryption message, and encryption message feedback is given
Academic Verification System, during encryption and transmission, the first identification code is not changed or damaged.
On this basis, academic Verification System receive the user using the first private key to the first identification code encryption after
3rd identification code, while the second public private key pair is generated using asymmetric encryption mode, and using the second private key to the 3rd identification code
It is encrypted, generates the 4th identification code, while generate checking message.Checking message is used to instruct academic Verification System by the
In four identification codes write-in purpose block.
The first identification code is carried out by using the first private key and the second private key to be stored in purpose block again after encrypting twice
In, the security that the first identification code stores can be improved, improves the reliability of academic authentication result.And the first private key and second
Private key is grasped respectively by user and academic Verification System respectively, and this reduces the risk of private key leakage, further increases the
The security of one identification code storage.
Meanwhile academic Verification System preserves the first public key and the first private key, in a step 309, to first position information pair
The data record answered is decrypted, and obtains the target educational background information of the storage location storage identified in first position information.
Step 308, according to checking message by the 4th identification code write block chain purpose block in, record the 4th identification code
First position information in purpose block；
In the present embodiment, checking message is used to confirming the legal identity of user, and then academic Verification System can be according to testing
Demonstrate,prove message to write the 4th identification code in the purpose block in block chain, academic Verification System can record and generate the 4th identification code
Storage location in purpose block.Specifically, the storage location of the first identification code after encryption can be the first storage location.
Wherein, the first storage location can be the specific digital value for representing line number.
Step 309, first position information is sent to user, so that user is according to the first identification code and first position information
Obtain academic information.
First identification code of generation is sent to after user by academic Verification System, it is also necessary to also sends out first position information
User is given, the first identification code and first position information can be submitted to any inquirer by user as inquiry voucher, so that
Inquirer can inquire about acquisition of credentials educational background information according to both and verify the authenticity for the academic information that user provides.
