Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
The electronic signature information contains signature information of a signer, and the traditional way of authenticating through notes is converted into the way of authenticating through a personal electronic certificate, so when a user opens and views a signature document, whether a personal signature on the document is valid or not needs to be judged by viewing the personal signature on the signature document.
Generally, when a signature document is checked in an online mode, a signed document, such as a PDF-formatted document, is converted into a file stream and is transmitted to a user foreground, the user foreground analyzes the PDF through a code insertion component, and analyzes the document into a browser according to a layer mode, generally, the content of an original document is a first layer of the layer, and a signed picture is a second layer, so that a user can see the picture signed by the user on the signed document. If PDF is analyzed through the code inserting assembly, only the image layers in the PDF file can be analyzed, the content of a general file is the first layer, the content of a signature picture is the second layer, and therefore a user cannot check the signature information of the document in a picture clicking mode, such as the identity information of a signer, whether a certificate is valid or not, a signature issuing mechanism and the like, so that the identity valid information of the signer cannot be confirmed, and the signature is easily issued by people.
In addition, since the code insertion component cannot perform tamper-proof verification on the file, after the file is tampered, the prompt that the file is tampered cannot be visually seen on the user interface, so that the user may use the tampered file.
The embodiment of the invention provides an electronic signature verification method which can be generally applied to equipment such as a verification server, and when a user clicks a signature file through a browser or a document reader, the browser or the document reader is connected with the verification server on line through a network and sends verification information to the verification server, and the verification server verifies the electronic signature information by operating the method. The authentication server also typically needs to be connected to a third party authority server in order to verify the validity of the electronic signature, such as: a certificate authority server, a national security management center server, a bank management authority server, or the like.

And the verification server analyzes the user electronic signature information through a code insertion technology to obtain a signature stream file of the user electronic signature information. And meanwhile, intercepting the signature picture of the second layer by a code insertion technology.
Step 102: converting the signature stream file into a PDF signature file;
and after the verification server acquires the signature stream file of the user signature information and the picture information of the user electronic signature, converting the signature stream file into a PDF signature file. Of course, the file can be converted into a file in other format, and here we take a PDF format file as an example for explanation.
Step 103: carrying out validity verification and tamper-proof verification on the PDF signature file;
and after converting the signature stream file into a PDF signature file, a verification server verifies the PDF signature file, wherein the verification comprises validity verification and anti-tampering verification, one is to verify the validity of the signature, and the other is to verify whether the PDF signature file is tampered.

The validity check needs to be performed through a certificate authority authorized by the country, so that the verification server needs to send the PDF signature file to the certificate management server, and the certificate management server performs validity check on the related information in the PDF signature file and feeds back the check result to the verification server.
And (3) tamper-proof verification:
the tamper-proof verification mainly verifies whether the content of a file is modified, verification information in the PDF signature file needs to be extracted, the file content is verified through an encryption algorithm, and here, a common MD5 algorithm is adopted to verify the PDF signature file. And the verification server calculates an MD5 value, a user signature public key in the PDF signature file and a user private key signature MD5 value in the PDF signature file according to the PDF signature file, judges whether the three values are modified, if so, indicates that the file content is tampered, and if not, indicates that the file content is not tampered.
Step 104: displaying the picture information of the user electronic signature according to the validity verification result and the anti-tampering verification result;
and when the verification is finished, the verification server feeds back a verification result to the user browser or the file reader, and the verification result is presented in a picture and link mode and is used for replacing picture information in the original user electronic signature.
The verification server converts the electronic signature picture into a picture + link form and feeds back the picture + link form to a user online browsing interface, the mark on the picture can directly view the result of signature verification and the result of file tampering, and the link is used for displaying the details of the electronic signature verification.
