Description
Technical field
Electric signing verification method of the present invention, it is especially a kind of to be used to verify the side whether papery license content is tampered
Method.
Background technology
At present, during electronics license use, it is necessary to by electronics license printout be papery license, but output
How document content authenticity and validity have verified that into problem it is therefore necessary to design a kind of specialized application after papery license
The method whether being tampered in verification papery license content.
The content of the invention
The technical problem to be solved in the present invention is：Lack in the prior art to the papery license of electronics license printout
Distort verification method.
In order to solve the above-mentioned technical problem, the side whether papery license content is tampered is verified the invention provides a kind of
Method, comprises the following steps：
Step 1, the generation of electronics license, is concretely comprised the following steps：
Step 1.1, it is that the electronics license of each type generates the template of its set form, each template gives unique template
Number and the formation of electronics license template is made a summary, recycle private key to form template signatures to summary encryption；
Step 1.2, select a kind of electronics license template, to template in fill in all fillers of electronics license and generate complete electricity
Sub- license file；
Step 1.3, all fillers filled in step 1.2 formation is made a summary, recycles private key to form filling to summary encryption
Item signature；
Step 1.4, by template number, template signatures, all fillers and filler signature with prescribed form formation electron number
According to, then electronic data formed into Quick Response Code, and Quick Response Code is placed on to the blank space for the electronics license file that step 1.2 is generated,
Form the electronics license with Quick Response Code；
Step 1.5, electronics license printout step 1.4 formed is papery license；
Step 2, the authenticity verification of papery license, is concretely comprised the following steps：
Step 2.1, the electronics license template formation license ATL in steps for importing 1.1；
Step 2.2, scanning papery license on Quick Response Code, from Quick Response Code preserve data in obtain template number, template signatures,
All filler and filler signatures；
Step 2.3, all fillers obtained in step 2.2 are subjected to processing and form summary H；
Step 2.4, the private key mark in the filler signature obtained in step 2.2 obtains corresponding public key, uses public key
H1 is obtained to the filler signed data decryption obtained in step 2.2；
Step 2.5, H and H1 are compared, if identical, then it represents that all fillers preserved in papery license Quick Response Code are not usurped
Correct one's mistakes, if it is not the same, then representing that all fillers preserved in papery license Quick Response Code are tampered with；
Step 2.6, corresponding electronics license template is obtained from license ATL according to the template number obtained in step 2.2,
And processing formation summary H2 is carried out to electronics license template content；
Step 2.7, according to the public key obtained in step 2.4, data are carried out to the template signatures obtained in step 2.2 using public key
Decryption, obtains H3；
Step 2.8, H2 and H3 are compared, if identical, then it represents that the electronics license template content preserved in papery license Quick Response Code
It was not tampered with, if it is not the same, then representing that the electronics license template content preserved in papery license Quick Response Code is tampered with；
Step 2.9, if step 2.5 and step 2.8 compare all same, by the electronics license template and step that are obtained in step 2.6
A new electronics license file of all filler combination producings obtained in 2.2；
Step 2.10, new electronics license file step 2.9 generated is compared with papery license document content, if phase
Together, then it represents that paper document content was not tampered with, checking paper document passes through, if it is not the same, then representing paper document
Content is tampered with, and checking paper document does not pass through.
The electronics license for being adopted as each type generates the template of its set form and gives each template unique number,
And template is obtained according to unique reference number, reduce the two-dimensional code data capacity of generation, reduce the memory capacity of electronics license, conveniently deposit
Storage；The data transfer of an electronics papery is carried out using Quick Response Code, the papery checking of papery license content is easy to implement.
As the further limits scheme of the present invention, the formation of electronics license template is made a summary in step 1.1, is specifically by electricity
All the elements in sub- license template carry out Hash operation, obtain summary info as input.
As the further limits scheme of the present invention, template label are formed to summary encryption with private key described in step 1.1
Name, specifically refers to digital signature value obtained from summary is encrypted using the signature private key in digital certificate.
As the further limits scheme of the present invention, digital certificate refers to be stored in be used to encrypt and numeral in intelligent KEY
The digital certificate of signature computing.
As the further limits scheme of the present invention, by all fillers obtained in step 2.2 in step 2.3
Reason forms summary H, is specifically, as input, to carry out Hash operation using all fillers of acquisition, obtains the H that makes a summary.
As the further limits scheme of the present invention, filler signature is formed to summary encryption using private key in step 1.3
And using public key H1 is obtained to the decryption of filler signed data in step 2.4, particular by asymmetric key algorithm, realize
The encryption of private key and the decryption of public key.
As the further limits scheme of the present invention, according in the filler signature obtained in step 2.2 in step 2.4
Private key mark obtains corresponding public key, specifically refers to the public key information extracted from the digital certificate of filler signing messages.
As the further limits scheme of the present invention, by the template and step 2.2 that are obtained in step 2.6 in step 2.9
A new electronics license file of all filler combination producings obtained, specifically refers to utilize document synthetic technology by all fillings
Item field, which is filled into, generates new file in template.
The beneficial effects of the present invention are：The electronics license for being adopted as each type generates the template of its set form simultaneously
Each template unique number is given, and template is obtained according to unique reference number, reduces the two-dimensional code data capacity of generation, reduces electronics
The memory capacity of license, convenient storage；The data transfer of an electronics papery is carried out using Quick Response Code, papery license is easy to implement
The papery checking of content.
