Description
Technical field
The invention belongs to the generation of antifalsification label and the field of information processing of identification, be specifically related to a kind of new
The processing method of type antifalsification label, this antifalsification label comprises the antiforge function of digital watermarking and laser hologram.
Background technology
Information anti-fake and the combination of physical security technology, be the development trend of current anti-counterfeiting technology.Tradition
Main flow physical security technology be mainly laser holography；And information anti-fake aspect, digital watermarking skill
Art is a kind of novel effective counterfeit protection measures.Laser holography and digital watermark technology are combined,
It it is a kind of well associated methods of physical security and information anti-fake.
Laser holography started to be applied to anti-counterfeit printing field from late 1980s, conventional
In making antifalsification label, apply the earliest in drinks, Folium Camelliae sinensis and cosmetic package industry.It is attached to product
Packing material surface, is one of more popular counterfeit protection measures.At the beginning of the nineties, fake and sell-fake-products is at Nicotiana tabacum L. row
Industry overflows, and the Medicated cigarette sold by illegal channels every year reaches 1,000,000 big casees.In the face of sternness
Situation, laser anti-counterfeit label technique solves a false proof difficult problem in time.But, traditional laser anti-counterfeit mark
Sign and there are some problems in actual applications: conventional hologram is at plastics by holographic metallic plate
Press mold on film, format or the pattern of the hologram which is made are extremely limited, only
The picture and text that the printing of repetition is identical can be used for.If adulterator obtains the pattern of these laser images,
Can quickly copy.
Digital watermark technology refer to use information processing method, digital multimedia data (image,
Audio frequency, video etc.) middle some special security information of embedment, for proving the copyright of product, as solution
The certainly evidence of copyright conflict, integrity etc..Image after embedment watermark information needs conventional attack
There is certain robustness, and the information of embedment has invisibility, does not affect the vision of original image
Effect.
Currently utilize the antifalsification label technology of antiforge laser holographic, be usually and image is passed through specific process
It is printed on antifalsification label, and covers one layer of holographic laser film, reach false proof purpose.But, this
The image planting holographic label is macroscopic, but also can easily be duplicated imitation, thus anti-counterfeiting power
The highest.The solution generally improving label anti-counterfeit performance is further Study of Laser holographic security technology,
It is developed so far existing four generations, but the equipment price of Laser Holographic Counterfeit-proof Technique is expensive, it is desirable to be higher, nothing
Method is for the extensive marketing of antifalsification label.
Along with the personalization of packaging and the requirement to anti-counterfeiting technology are stepped up by people, laser originally
Holographic false proof shows its limitation day by day, and a kind of new false proof mode is needed in market badly.Therefore, will
The advantage of the technology such as digital watermarking and antiforge laser holographic combines, and makes anti-counterfeiting performance preferably anti-counterfeiting label
Sign, there is good market prospect.
For the ease of understanding the present invention, once relevant term is explained:
Fourier-Mellin Transform spectrogram: Fourier-Mellin Transform (Fourier-Mellin Transform,
FMT) being a kind of effective graphical analysis and the mathematical tool of identification, the spectrum results of its conversion has rotation
Turn, the invariance of Pan and Zoom, noiseproof feature is preferable.Fourier-Mellin Transform spectrogram is right
Original image is sampled, and obtains discrete point distribution, through the figure that Fourier-Mellin Transform obtains.
