Abstract
The invention discloses an anti-fake identification method of color images. The anti-fake identification method of the color images includes following steps: collecting original color image data; analyzing and storing the original color image data; collecting color image data to be identified; analyzing the color image data to be identified, and comparing the color image data to be identified with the original color image data. The anti-fake identification method of the color images can improve anti-fake levels of the color images according to color passwords, and other factories difficultly produce new fake color images consistent with original color images on the premise of not obtaining original color passwords, and therefore the anti-fake identification method prevents the original color images from being faked by the other factories, and greatly protects benefits of manufacture factories of the original color images. Furthermore, customers can effectively identify authenticity of the color images by using the anti-fake identification method of the color images.
Description
Technical field
The present invention relates to a kind of Antiforge recognizing method of coloured image.
Background technology
In Traditional Printing Industry, the false proof measure of the coloured image to printing is all generally to reach false proof object by anti-forgery ink printing, and this false proof measure is comparatively single, also comparatively simple, very easily copied by other printing factories, thereby greatly damaged the interests of the manufacturer of original color image.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome technological deficiency recited above, and a kind of Antiforge recognizing method of coloured image is provided.
In order to solve technical matters recited above, the present invention takes following technical scheme:
An Antiforge recognizing method for coloured image, comprises the following steps:
Original color image data acquisition: original color image is scanned, obtain original color image information, comprise and obtain original color image and original color image is processed to the original ink color digital information forming;
Analyzing and processing also stores: ink colors numerical information is processed, formed primitive color password, primitive color password is stored in database;
Color image data collection to be identified: scanning needs the coloured image to be identified of identification, obtains color image information to be identified, comprises coloured image to be identified and ink colors digital information to be identified;
Analyzing and processing comparison: ink colors digital information to be identified is processed, obtain new color password, new color password and primitive color password are compared, if two color passwords are consistent, coloured image to be identified is consistent with original color image, is genuine piece; Otherwise coloured image to be identified is fakement.
In analyzing and processing storing step, also comprise original color image carried out to the processing of colour gamut color separation, obtain the original color color separation information in the outer and/or colour gamut of colour gamut, by the original color color separation information storage obtaining to database; In analyzing and processing and compare in step, also comprise coloured image to be identified is carried out to the processing of colour gamut color separation, obtain the new color separation information outside colour gamut and/or in colour gamut, new color separation information and original color color separation information are compared, if two color separation information are consistent, coloured image to be identified is consistent with original color image, is genuine piece; Otherwise coloured image to be identified is fakement.
In analyzing and processing storing step, also comprise original color image carried out to grey balance processing, obtain including the original grey balance information of neutral gray balance information and/or colored grey balance information, by the original grey balance information storage obtaining to database; In analyzing and processing and compare in step, also comprise coloured image to be identified is carried out to grey balance processing, obtain including the new grey balance information of neutral gray balance information and/or colored grey balance information, new grey balance information and original grey balance information are compared, if two grey balance information are consistent, coloured image to be identified is consistent with original color image, is genuine piece; Otherwise coloured image to be identified is fakement.
Color password is to utilize the identical double exposure of print color vision site, and different metamerism characteristics is determined.The repetition probability of color password is tens billion of/mono-, therefore has " two wires is false proof " function truly.The ink using through design, can effectively increase imitated difficulty.Can by password color dexterously composite design become different pattern, or disperse to be arranged in different parts, make imitated person be difficult for discovering and analyzing.Can also utilize high definition printing net-point size and shape to change, netting twine combination of frequency etc. increase the technical characterictic of color password, and these can further increase imitated difficulty.
Antiforge recognizing method provided by the invention; improve the false proof rank of coloured image by color password; other factories are not obtaining under the prerequisite of primitive color password; be difficult to copy out the new coloured image consistent with original color image; thereby effectively avoid other producers to copy original color image, greatly protected the interests of the manufacturer of original color image.And consumer also can identify by method provided by the invention the true and false of coloured image effectively.
Embodiment
