Network screen encoded anti-fakery method

Abstract

This invention relates to an anti-falsification method with mesh screen encoding used in electronic documents of government and other smilar cases. The method includes mesh screen technique using large and small mesh points to indicate "0" and "1" and combining the shapes and positions of the mesh points; the ways of character encoding and background encoding, as well as the relevant ways of background encoding and character encoding, with background encoding corresponding to characters in positions; structural way and error-correcting way of the mesh screen encoding. The mesh screen encoding has the properties of compression of information and safety, being difficult to distort and forge; being able to directly view and keep forever, specifically, when being used in bills of banks and tax, the contents of the bills can be stored in the lines of forms, and the printed bills and various files can be again input to computer.

Description

technical field [0001] The invention relates to an anti-counterfeiting method for screen coding used in electronic government or other similar occasions. Background technique [0002] In e-government or other similar occasions, a practical problem that needs to be solved urgently is whether to directly download various certification documents on the Internet and ensure the authenticity of these documents. It is an important problem to be solved urgently. At present, there is no good proposal in the world. [0003] In addition, whether the files printed out by the printer can be quickly re-imported into the computer. For example: if the report submitted from the lower level is to be input into the computer, it needs to be input again manually. If the file can be automatically input, that is, the file on the paper medium can also be recorded on the magnetic field. The media can also record file information, and can be directly input into the computer, so that the unification...

AI Technical Summary

Problems solved by technology

[0006] (1) It occupies a large printing area and can only be printed independently on a certain part of the paper medium;

[0007] (2) It cannot be implied in words, trademarks, patterns, etc., and partial anti-counterfeiting detection cannot be carried out;

[0008] (3) In terms of security, it is not easy to be encrypted, and the bar code can be copied, which is not suitable for anti-counterfeiting;

[0009] Some people in the United States and Japan proposed to encode the seal on the computer screen to identify the authenticity of the seal, but this encoding cannot be printed directly and cannot be realized on paper media.
