Problems solved by technology

These methods have certain disadvantages: firstly, the anti-counterfeiting ability of the shading texture is relatively weak; secondly, it requires the operator to use multiple software, many manual operations, and the process of generating anti-counterfeit documents is complicated; thirdly, the embedding process of all anti-counterfeiting information is Completed before printing, the completed electronic document data must be circulated and disseminated in a certain channel before it can reach printing output devices such as printers, which inevitably has the risk of being tampered with or destroyed during the intermediate circulation process; Finally, such methods usually do not track and trace the source of the document. Once the anti-counterfeiting information is attacked or discovered, the document cannot be anti-counterfeiting

Embodiment Construction

[0046] Now in conjunction with the accompanying drawings, the structural features of the present invention will be described in detail.

[0047] Provided in this embodiment is an anti-counterfeit generating method for a document, which is set in the driver of the printing device and includes the following steps:

[0048] Step (1), set anti-counterfeiting plaintext

[0049] Set anti-counterfeiting plaintext (anti-counterfeiting plaintext can be graphics, characters or numbers and their combination) such as figure 1 As shown, in this embodiment, the preferred anti-counterfeiting plaintext is a graphic, and a dot matrix image corresponding to the content of the anti-counterfeiting plaintext is generated for use;

[0050] Use the encoding method of Freeman chain code to encode the graphics, obtain the encoding of its shape, set figure 1 The difference code of the Freeman chain code of the graphic shape in the middle is "67166626";

[0051] Build a cloud, which can interact with t...

Abstract

The invention discloses a document anti-counterfeiting generation and identification method and a printing driver and system. The generation method comprises the following steps: (1) setting an anti-counterfeiting plaintext; (2) setting an encrypted image; (3) printing and outputting; the identification method comprises the following steps: (1) obtaining an encrypted image; (2) obtaining a decrypted image; (3) obtaining a graph in the decrypted image by using an image recognition algorithm; (4) data matching; wherein the document anti-counterfeiting printing driver comprises an anti-counterfeiting module, the document anti-counterfeiting system comprises a printing driver and an anti-counterfeiting module arranged in the printing driver, and the anti-counterfeiting module realizes documentanti-counterfeiting through the document anti-counterfeiting generation method. The method and the device are used for solving the problems that in the prior art, an anti-counterfeiting document embedded with anti-counterfeiting information is complex in manufacturing and printing and high in implementation difficulty, the risk that the document is tampered or damaged exists in the circulation process, the risk that the document is counterfeited by utilizing high-precision copying equipment, and the document cannot be protected after the anti-counterfeiting information is attacked or perceived.

Description

technical field [0001] The invention belongs to the technical field of printing anti-counterfeiting, and in particular relates to a method for generating and identifying anti-counterfeiting documents, a printing driver and a system. Background technique [0002] With the rapid development of scanners, printers, copiers and other equipment as well as scanning and copying technologies, it is relatively easy to forge documents of important economic value such as contracts and bills, so their forgery is becoming more and more rampant. It even brings huge economic losses to the whole society, thereby disrupting social stability. Therefore, at present, the security and anti-counterfeiting of documents with economic value such as contracts and bills are still facing challenges, and it is also an unavoidable problem in today's society. [0003] The security and anti-counterfeiting issues of printed output information are mainly related to three aspects: printing paper, printing ink...
