Embodiment Construction

[0047] In order to make the structure and advantages of the present application clearer, the structure of the present application will be further described below in conjunction with the accompanying drawings.

[0048] In order to verify the authenticity of electronic signatures in electronic documents such as contracts and agreements that are currently electronically signed, the embodiment of this application proposes a document signature verification method to strongly limit the relevant parameters of electronic documents in the form of signature codes In the later stage, the verification of the authenticity of the electronic signature is realized according to whether the signature code is the same.

[0049] Specifically, the file signature verification method based on the signature code proposed in the embodiment of this application, such as figure 1 shown, including:

[0050] S1. Obtain the signing device information used to perform the electronic signature operation, comb...

Abstract

The embodiment of this application proposes a document signature verification method based on a signature code, including obtaining the signature scene information, and calculating the signature scene information in combination with a preset algorithm to obtain a signature code; calculating the verification value of the signed document; receiving the signature verification sent by the requesting party Request, obtain the requester's permission ID to compare the signature code, calculate the verification value and signature code of the target signature file, if there is a difference in the signature code, reversely call the preset algorithm to restore the signature scene information, based on the requester's permission ID Filter the restored difference information, and feed back the filtered comparison result to the requester. A variety of information related to the signed document is obtained through a preset algorithm to obtain a signature code that can represent the strong uniqueness of the signed document, and the signature code and the check code representing the integrity of the signed document are stored on the server, and the received signature is verified The request is verified based on the signature code, which can effectively ensure the authenticity of the signed document.

Description

technical field [0001] This application relates to the field of file verification, in particular to a file signature verification method based on a signature code. Background technique [0002] For the electronic files that use electronic signatures that are becoming increasingly popular, the process of verifying their signatures is to calculate the hash value of the electronic file or obtain the CA certificate of the electronic file, and judge whether the hash value has changed or the integrity of the CA certificate To determine whether the electronic file has been modified. [0003] However, the current hash value calculation and CA certificate generation process are too dependent on the data of the signature file itself, which has obvious limitations. Contents of the invention [0004] The embodiment of this application proposes a document signature verification method based on a signature code. According to many parameters related to the signature document, the signat...
