Abstract
The invention relates to a printing anti-counterfeiting technology, in particular to a digital watermark anti-counterfeiting system for printing, which comprises a material to be printed on, a dominant pattern and digital anti-counterfeiting information. The digital watermark anti-counterfeiting system is characterized by also comprising a watermark pattern, a coding subsystem and a decoding subsystem, wherein the watermark pattern is a recessive pattern, the watermark pattern is generated from the digital anti-counterfeiting information by the coding subsystem, and the watermark pattern is restored into the digital anti-counterfeiting information by the decoding subsystem; and the watermark pattern is embedded in the dominant pattern and is printed on the material to be printed on. The invention aims at overcoming the defects in the prior art and providing a digital watermark anti-counterfeiting system of high safety.
Description
Technical field
The present invention relates to the antiforge technology, relate in particular to a kind of press figure watermark Antiforge system.
Background technology
For preventing identity document, currency, security, important sign or file etc. by imitated, people often adopt digital watermark, as Heisui River seal or plain boiled water seal, under specific light, can observe watermark identifier.Existing digital watermark has played the effect of hitting personation protection certified products to a certain extent; yet; existing digital watermark belongs to the dominance watermark; watermark identifier is a plaintext, visible; development along with printing technology and paper technology; imitated common watermark identifier no longer is high-leveled and difficult technology, and the security of common watermark anti-counterfeiting technology reduces greatly, and watermark is false proof by the imitated possibility that becomes.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part and a kind of safe digital watermark anti-fake system is provided.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of digital watermark anti-fake system, comprise stock, also comprise dominance pattern and digital anti-counterfeiting information, it is characterized in that: this digital watermark anti-fake system also comprises watermark recovery, coding subsystem, decoding subsystem, described watermark recovery is recessive pattern, described digital anti-counterfeiting information generates watermark recovery by described coding subsystem, and described decoding subsystem can be reduced to watermark recovery digital anti-counterfeiting information; Described watermark recovery embeds described dominance pattern, is arranged at described stock with mode of printing.
The digital watermark anti-fake system is characterized in that: described digital anti-counterfeiting information is voice messaging, and described watermark recovery is the phonetic code that adopts colourless magnetic ink to be provided with.
The digital watermark anti-fake system is characterized in that: described digital anti-counterfeiting information is pattern or Word message, and described watermark recovery is the printing original text through grating encryption.
The digital watermark anti-fake system is characterized in that: described digital anti-counterfeiting information is electronic document, and described watermark recovery is the binary digital information sign indicating number that is provided with by the magnetic ink seal.
The digital watermark anti-fake system is characterized in that: described electronic document is an encrypted document.
The digital watermark anti-fake system is characterized in that: described digital anti-counterfeiting information is electronic document, and described watermark recovery is the binary digital information sign indicating number that is provided with by the magnetic ink seal; Described electronic document is an encrypted document.
Digital watermark anti-fake of the present invention system, watermark recovery is recessive pattern, can not duplicate by modes such as photo scannings, and watermark recovery is that special coding subsystem generates, need special decoding subsystem just can be reduced into anti-counterfeiting information, have double anti-forge, have the security of height.
Embodiment
First embodiment of the invention is an a kind of digital watermark anti-fake system, comprise stock, also comprise dominance pattern and digital anti-counterfeiting information, it is characterized in that: this digital watermark anti-fake system also comprises watermark recovery, coding subsystem, decoding subsystem, described watermark recovery is recessive pattern, described digital anti-counterfeiting information generates watermark recovery by described coding subsystem, and described decoding subsystem can be reduced to watermark recovery digital anti-counterfeiting information; Described watermark recovery embeds described dominance pattern, is arranged at described stock with mode of printing.In the present embodiment, described digital anti-counterfeiting information is voice messaging, and described watermark recovery is the phonetic code that adopts colourless magnetic ink to be provided with.Certainly, as a kind of conversion scheme of present embodiment, described digital anti-counterfeiting information also can be pattern or Word message, and described watermark recovery is the printing original text through grating encryption.The grating encryption technology can adopt the grating encryption of prior art.Certainly, as another conversion scheme of present embodiment, described digital anti-counterfeiting information can also be electronic document, and described watermark recovery is the binary digital information sign indicating number that is provided with by the magnetic ink seal, and described electronic document can also be an encrypted document.
