Embodiment
Below preferred embodiment of the present invention is described in detail.
The present invention utilizes method for anti-counterfeit and the system of material self physical features identification, its objective is and utilize the uniqueness characteristic obtain label self physical features that the light-permeable material makes, come its true and false of unique identification by the transmission optics system, the cost of its realization of this kind technology is low, easily realize, and the easier identifying processing of image effect.
The inventive method and system utilize the physical features of material self, and such as its texture, density, height and/or color etc. need not extra anti-fake material, after identifying its physical features image, carry out digitized processing, form the physics characteristic, to realize the function of antifalsification label.The realization of the false proof mode of this kind can't be by the methods such as fluorescent ink printing clone, and the cost of simultaneously its realization can reach again enough low.This digitized processing procedure, those of ordinary skills know in the prior art, such as, after obtaining the fiber pattern image, can obtain the distributed intelligence of fiber, the trend of fiber, flexibility, length etc., these information can be used as the Characteristic of Image data and extract.Because the distribution of fiber is full stochastic process, be the will of " God ", therefore just there is not the identical paper of fiber distribution.For another example, if when in the characteristic informations such as its density, height and color one or more are made up identification, just can obtain unique recognition result, the physical features data after its processing are unique.
Take paper as example, contain a large amount of vegetable fibres in the paper, these fibers are lack of alignment in process of production, and are difficult to by manually carrying out imitated in batches.Even by ink print, there is not resolution to be large enough to clone physical features in the amplification situation yet; Even if enough print resolution are arranged, can in limited area, print the form of fiber, because the present invention adopts transmitted light, the image that collects also will be counterfeit information comprehensive of forging the fibre morphology information of paper itself and printing, and the simple counterfeit information of printing is that the physical features data of impossible and original genuine paper are identical with information.If can be in advance textural characteristics in paper is determined certain zone, and with this feature digitizing, just can utilize this digitalized signature to carry out truth identification.
Be illustrated in figure 4 as the paper physical characteristic image in the optical amplifier situation.Can find out from this physical features image, the texture of fiber is more clearly, and is unordered.Process, after the method for pattern-recognition processes it, just can extract the fibre image feature by image, carry out the number processing, for truth identification after this.This processing is comparatively common processing procedure, for example after obtaining fibre image, can obtain the distributed intelligence of fiber, the trend of fiber, flexibility, length etc., and these information can be used as the Characteristic of Image data.Certainly can also use the statistical method of a lot of classics, such as gray level co-occurrence matrixes, Hu displacement etc. not, the classic algorithm of perhaps using image local feature to describe: SIFT or SURF etc., these algorithms are common by prior art, do not repeat them here.
The present invention utilizes the method for anti-counterfeit of material self physical features identification, mainly for the material of light-permeable, adopts the optically detecting mode of transmission, and as shown in Figures 2 and 3, it has comprised following steps:
At first, pre-determine the position that gathers physical features and the predetermined enlargement factor that is enough to the physical features of recognition material own at material to be identified, material to be identified is placed on light source and gathers between the optical system and optical sensor of image, obtain the physical features image that optically detecting arrives after the transmission; Should predetermined enlargement factor not necessarily amplify, also can be to dwindle or maintain the original state, and do not amplify and dwindle and carry out imaging.Why can not amplify the collection of carrying out the physical features image, when reason is to adopt transmission mode, the physical features image that printing opacity forms is more clear, no longer need necessarily to amplify how many multiples and can obtain clearly physical features image, compare the image acquisition that adopts the reflected illumination mode, the cost requirement of its realization is very low, and to all greatly reductions of requirement of optical system and optical sensor, an illuminance that only needs to improve light source can form clearly physical features image.
Then, the physical features image that collects is carried out digitized processing, extract physical features data wherein, and be recorded to property data base; When differentiating this material true and false, by above-mentioned transmission type optical system this material is adopted same enlargement factor equally, and at same position acquisition physical features image, adopt same feature extracting method to carry out digitized processing, to obtain physical features data to be identified.
Pre-stored physical features data are carried out pattern-recognition and are compared in the physical features data that this is to be identified and the property data base, judge if can access consistance, can judge that then this material is true, otherwise be puppet.Like this to the important material such as bill, card even cloth for example collectibles just can carry out anti-counterfeit recognition, this identification need not depend on the special processing of anti-counterfeiting technology technique, just improving identification equipment gets final product, realized uniqueness and the antifalsification of utilizing physical features to identify, and the equipment cost that realizes has practical low-cost characteristics, and the physical features image false-proof effect of realization is splendid.
In the method for anti-counterfeit and system that utilizes material self physical features identification of the present invention, described material can adopt the physical support of any light-permeable, paper for example, the cloth sheet, the article that plastic foil or plastic cards etc. are transparent or semitransparent, especially for the physics identification of collectibles itself, will have actual especially meaning.Physical features in the above-mentioned physical features image generally includes fiber pattern, density and/or frequency etc.
The present invention utilizes in the method for anti-counterfeit of material self physical features identification, better way of example is, in above-mentioned optical sensor and optical system, do not adopt fixing enlargement factor (yet comprising minification) when obtaining the physical features image, but adopt unfixed enlargement factor, namely change multiple according to the multiple scope that can identify the physics characteristic and gather the physical features image, record simultaneously its multiple, simultaneously must its enlargement factor of record in the resulting like this physical features data.Thus, also adopt same multiple to carry out collection and the identification of image when identification, this mode itself has just increased the difficulty of copying.
Anti-counterfeit recognition when preventing that network is unavailable can not be carried out, but it is a kind of in the alternative anti-counterfeit recognition scheme without the network time spent that method for anti-counterfeit of the present invention also provides, soon the physical features data after the digitized processing are recorded in the two-dimension code, and this two-dimension code is printed onto material surface to be identified; When pattern-recognition, identify contrast by the data that read in this two-dimension code, certainly, for increasing the anti-counterfeiting performance of data, also can carry out first cryptographic calculation to the data of putting down in writing in this two-dimension code.So, when not having the state of networking, can directly by after the record and pattern-recognition to two-dimension code, judge the true or false of article.It is the database of the independent data of record that this two-dimension code can be understood as.
The present invention utilizes the Antiforge system of material self physical features identification, such as Fig. 2 and shown in Figure 5, it is for the anti-counterfeiting substances to be identified of light-permeable, setting comprises: the property data base of pre-stored physical features data in the accessing Internet, set in advance the identifying processing of several feature extractions, printing device, the physical features data after the identification are stored in this property data base.Be provided with optical system and optical sensor in each described feature extraction, the printing device, and light source, described material to be identified is placed between optical system and the light source, described optical system is used for the image of transmission is adjusted sharpening, can adjust image according to predetermined enlargement factor, amplify and obtain the physical features image through precalculated position and the predetermined enlargement factor that is enough to the physical features of recognition material own; Described optical sensor is obtained the physical features image of this predetermined enlargement factor; And an image processing module is used for described physical features image is treated as the physical features data, and this processing procedure is that prior art is known, does not repeat them here; One pattern recognition module is used for comparing the storage data of described property data base and the physical features data that described image processing module generates, and judges the true and false of described material to be detected, if obtain that consistance is judged then be true, otherwise is false.
The Authentication devices that is used for distinguishing true from false also arranges same optical system, optical sensor and light source, in order to carry out identical Image Acquisition action and image processing process.The pattern-recognition mode of described pattern recognition module can but be not limited to classical theory of statistics method or local feature description's method (SIFT or SURF) or svm classifier device etc.The algorithm of these pattern-recognitions is just given unnecessary details no longer one by one classifying too much in the technology at present.
Described Authentication devices be used to distinguishing true from false can adopt the mode of on line, obtains data to be verified from property data base, compares; Also can adopt offline mode, from be printed on the two-dimension code that material shows, obtain physical features data to be contrasted.
