Problems solved by technology

Since this method uses digital watermarking technology, a large amount of information cannot be embedded on paper, and encoding can only be performed on a few words, so it is difficult to completely prevent the content of the certificate from being tampered with.
In addition, there are few reports on anti-tampering technology for copies of certificates
[0005] To sum up, the existing technology cannot completely solve the problem of anti-counterfeiting and anti-tampering in printed media certificates, especially copies.

Embodiment 1

[0068] Combine below figure 1 with figure 2 Describe the process of anti-counterfeiting treatment methods for printed media certificates and their copies:

[0069] The anti-counterfeiting processing method of the printed medium certificate certificate and its copy is composed of a screen code embedding system and a screen code recognition system. The screen code embedding system realizes the embedding method of information in the printed medium certificate certificate. The code recognition system realizes the recognition method of the information embedded in the printed media certificate and its copy.

[0070] The screen code embedding system is installed in the computer. Through the cooperation of the computer host and the keyboard, monitor, printer, scanner and other equipment, the shading pixels can be used to make the shading image at the same time in the gap of the certificate. Enter the screen code with anti-counterfeiting information and print it out on ordinary printing pa...

Embodiment 2

[0099] The anti-counterfeiting treatment method of the printed medium certificate certificate and its copy can also be made by embedding the information in the printed medium certificate certificate into a screen coded information embedded chip, and the information embedded in the printed medium certificate certificate and its copy can be embedded The identification method is made into a screen coded identification chip, and then these two chips are connected to a copier or an all-in-one machine to realize the embedding method and identification method of the information in the printed media certificate certificate, and the copier (integrated copier) can be protected against Copy function, trace function, anti-tamper function, steganography function, secret transmission function, etc.

[0100] Figure 14 It is a schematic diagram of the internal connection with the above-mentioned screen code information embedded chip and screen code recognition chip for the multifunction machine ...

Abstract

The related false proof information embedding method for print-media certificate comprises: printing the false proof shading image in certificate content gap, and embedding the false proof information of screen code on the shading without changing shading pixel feature. The corresponding recognition method comprises: scanning the print media to recognize the false proof information, and comparingboth the false proof information and certificate or copy together. This invention can also recognize the copy, needs low cost, and benefit to spread.

Description

Technical field [0001] The invention belongs to the field of information processing, in particular to an anti-counterfeiting processing method for printed media certificates and their copies. Background technique [0002] With the continuous development of innovative technologies such as copiers, printers, scanners and other office automation equipment, their printing or scanning resolutions are getting higher and higher. The above-mentioned equipment can be used to print or copy printed media certificates and certificates, and the effect can be completely fake. In addition, the printed media certificate is scanned into a computer through a scanner to form a data image. The image processing software in the computer can be used to easily modify the image to achieve the purpose of tampering. [0003] Nowadays, not only the originals of all kinds of printed media certificates are used in society, but in many cases, the copies of all kinds of printed media certificates are used in larg...
