Abstract

The invention relates to a multiparameter multivariable multielement encryption anti-fake information storage trademark. The multiparameter multivariable multielement encryption anti-fake information storage trademark can process binary anti-fake information to generate binary modulation signals through multielement encryption and channel coding. The anti-fake information is embedded in a whole trademark page through orderly change of amplitude-modulated dot conductivity with a circular table lookup modulation mode method. The anti-fake information can be identified from any fragment at the time of trademark identification and the multiparameter multivariable multielement encryption anti-fake information storage trademark can be used for all kinds of anti-fake trademarks.

Description

The polynary encryption anti-counterfeiting information storage of multiparameter multivariate trade mark
affiliated technical field:
The present invention relates to a kind of anti-false trademark, particularly the polynary encryption anti-counterfeiting information of a kind of multiparameter multivariate is stored trade mark, this trade mark can be kept at binary add tight defense fake information on the trade mark page and realize the false proof of trade mark, and what this trade mark can be for extensive stock is false proof.
background technology:
Anti-false trademark, claim again antifalsification label, anti-counterfeiting mark, anti-false sign, anti-fake label, is a kind of proof label of discerning the false from the genuine, preventing personation, be in the commodity process of circulation people for distinguishing true and false, the sign of distinguishing the commercial quality quality of merchandise resources.Trademark anti-counterfeit is related to businessman, client and market safety, is related to protection businessman and client's interests.The trade mark of China has carried out innovation audaciously; adopted laser anti-counterfeit, the core micropore is false proof, invisible graph is false proof, magnetic ink is false proof, microfilm of characters is false proof, indicia distribution is false proof, light carving is false proof etc.; but the false proof struggle with fraud is high-tech trial of strength; advanced anti-counterfeiting technology has certain ageing again; so; must constantly promote trade mark anti-fake technique; could false proof with fake in forever maintain the leading position, this is also that protection businessman and client's interests are maintained the commodity safe basic assurance that circulates.
summary of the invention:
For reliability and the security that improves trademark anti-counterfeit, the deficiency that the present invention is directed to existing trademark anti-counterfeit existence is improved existing trade mark anti-fake technique, a kind of anti-counterfeiting information storage trade mark has been proposed, this trade mark is by the change to amplitude electric conductivity in brand printing, encryption anti-counterfeiting information is embedded on the whole trade mark page with scale-of-two coded signal form, can identify encryption anti-counterfeiting information when brand recognition from any one fragment, therefore there is very strong disguise and crush resistance.
The technical solution adopted for the present invention to solve the technical problems is:
Anti-counterfeiting information storage trade mark, by trade mark page paper, be printed on amplitude on trade mark page paper, be printed on the horizontal scanning line on trade mark page paper, the column scan line be printed on trade mark page paper forms, image and word on trade mark page paper consist of amplitude,
Binary add tight defense fake information according to storage, a part of amplitude on trade mark page paper is printed and is formed by electrically conductive ink, another part amplitude on trade mark page paper is printed and is formed by dielectric ink, and the horizontal scanning line on trade mark page paper and column scan line are printed and formed by electrically conducting transparent printing ink
The horizontal scanning line be printed on trade mark page paper has the N bar, the column scan line be printed on trade mark page paper has the M bar, the amplitude be printed on trade mark page paper is divided into the capable M row of N on the trade mark paper, amplitude neatly is matrix and arranges on trade mark page paper paper, allow i get 1 to N, allow j get 1 to M, j bar column scan line on trade mark page paper is electrically connected to the basal surface of each amplitude of the row of the j on trade mark page paper, the upper surface of each amplitude that the i bar horizontal scanning line on trade mark page paper is capable with i on trade mark page paper is electrically connected to
In the time the binary message of trade mark page stores need to being read, be set to successively high level to N bar horizontal scanning line by the 1st on trade mark page paper,
When the 1st horizontal scanning line on trade mark page paper is set to high level, the binary message of the 1st row storage on trade mark page paper is exported from the 1st column scan line to M bar column scan line with 0,1 code form, the 1st row on trade mark page paper is printed the amplitude output binary message 1 formed by electrically conductive ink, the 1st row on trade mark page paper is printed the amplitude output binary message 0 formed by dielectric ink, can repeat above-mentioned readout to other row on trade mark page paper
In order to realize the encryption storage of trademark anti-counterfeit information, at first image false-proof information and character anti-counterfeiting information are carried out to digitized processing, utilize the binary system anti-counterfeiting information table of 8 one group of image false-proof information and character anti-counterfeiting Information generation, for preventing from ciphering process producing information spillover, each 8 one group of binary system anti-counterfeiting information in binary system anti-counterfeiting information table are expanded to 32 one group of binary system anti-counterfeiting information, generating high 24 is 0 32 one group binary system anti-counterfeiting information table entirely, 32 binary system anti-counterfeiting information of i in 32 one group binary system anti-counterfeiting information table group are denoted as
Figure 503216DEST_PATH_IMAGE001
, 32 binary add tight defense fake informations of the group of the i in 32 one group binary add tight defense fake information table are denoted as to H i, i is greater than 0 positive integer, and the eight-digit binary number encryption parameter is denoted as respectively
