Problems solved by technology

The application of one-dimensional barcode can improve the speed of information entry and reduce the error rate, but one-dimensional barcode also has some shortcomings: the data capacity is small (only about 30 characters can be stored), it can only contain letters and numbers, and the barcode size Relatively large (less space efficient), the barcode cannot be read after damage
[0005] (2) Only applicable if image 3 The content shown is a relatively simple web page file format that cannot support such as Figure 4 Display of electronic documents and electronic contracts in other formats as indicated
[0009] 1. Large information capacity

Embodiment Construction

[0118] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:

[0119] Such as Figure 5 As shown, a visual electronic signature method includes the following steps:

[0120] (1) convert the electronic file into a format file, and the format file in the present embodiment is a CEB file;

[0121] Commonly used electronic documents such as Word, Excel, and WPS are converted into CEB (Chinese E-Document Basic) files through Founder Apabi production software in this embodiment. CEB files are format files independently developed by Founder. The converted CEB The display effect of the file is consistent with that of the electronic file before conversion, and the CEB file will not have different display results due to different machines and different Windows operating systems.

[0122] (2) Sign the format file obtained in step (1), i.e. the CEB file, specifically including the following methods:

[0123] 1) Perform bitstream...

Abstract

The invention relates to a visible electronic signature and validation method. Wherein, converting the E-file into format file for signing by pages; using two-dimension bar code contained certificate label and sign method and result of page as the display for the signature. Compared with prior art, this invention supports display for different formats, has larger memory, and can validate the authorization and find out the print source.

Description

technical field [0001] The invention belongs to the technical field of electronic signature and authentication, and in particular relates to a visualized electronic signature and authentication method. Background technique [0002] The technology for signing electronic documents is very mature. After the "Electronic Signature Law" was officially implemented in 2004, electronic documents can be used as legal evidence after being signed. At present, electronic signature technology is mainly used for proofreading of identity authentication and information integrity, and is widely applicable to fields such as e-commerce and e-government. However, the visualization of electronic signatures and mutual authentication with actual paper documents are very weak. Under the premise that e-commerce and e-government affairs cannot cover all fields, how to ensure the visualization of electronic signatures of electronic documents and mutual authentication of paper documents is particularly ...
