Electronic signature method based on electronic document image object

Abstract

The invention discloses an electronic signature method based on an electronic document image object, a signature procedure and signature verification process. The invention comprise a UKEY processingmodule, an image processing module, a signature processing module, a universal algorithm module and an electronic document control module, and a view module is connected with the image processing module, the signature main body module, the seal module and the digital signature module; and the signature processing module is in signal connection with a general algorithm module. The electronic signature is intercommunicated with a mobile terminal at a PC personal computer end to verify the integrity and authenticity of documents. A seal is stored in an electronic document in a simple image objectmode, and a computer cannot be attacked. The invention can be suitable for electronic document office software, and is beneficial to improving the compatibility, stability and maintainability of software products.

Description

technical field [0001] The invention relates to electronic signature technology, which is suitable for the intercommunication of PC electronic signatures and mobile terminal electronic signatures, and in particular relates to an electronic signature method based on electronic document image objects. Background technique [0002] In recent years, with the continuous development of government informationization and enterprise informatization, electronic office software has also achieved great development, and many excellent office software manufacturers have emerged in China, such as Jinshan, Yongzhong, and Zhongbiao. In order to facilitate the integration of OA enterprises, the electronic office software uses the MSO VAB interface specification of Microsoft office software. [0003] However, traditional electronic signature products based on electronic documents such as doc, docx, xls, xlsx, etc. generally use ActiveX technology. Due to the technical characteristics of Active...

AI Technical Summary

Problems solved by technology

[0007] 1. There are security risks that may affect the computer

The signature control of ActiveX technology can operate all resources of the computer, which is easy to attack the computer

[0008] 2. Poor compatibility, it can only be used on individual versions of electronic document office software

The signature control of ActiveX technology cannot adapt to the high-version electronic document office software

Limit the application of electronic signature products

[0009] 3. Cannot adapt to the development needs of new electronic document office software

Since various electronic document office software supports ActiveX technology differently, some office software does not even support it, which greatly restricts the use of electronic signature products

[0010] 4. Cannot adapt to the development needs of "Internet +" technology

Since mobile terminal systems such as Android and Apple do not support ActiveX technology, electronic office software cannot normally use existing traditional electronic signature products on mobile terminals.
