Abstract
The present invention relates to a grating fingerprint anti-counterfeit mark which combines a grating technique and dactylography. The present invention is characterized in that the present invention is composed of a grating plate (1), a fingerprint image (2) and non-dry adhesives (3), wherein grating streaks are not scratched on the half part of the grating plate. When the surface of the mark is irradiated by light, an image superimposed by gratings and fingerprints appears at the grating and the shape of the image can stepless deform continuously in company with the change of irradiating angles. A tailor-made comparison mirror can be used for comparing suspicious marks and observing a changing rule to identifying truth and false, the inherent characteristics of the fingerprints can be seen at the position of the mark, which is not scratched by the grating, and can be checked through comparing with the suspicious mark, or the truth and false can be rapidly identified by a fingerprint automatic identifier. The mark is an integral anti-counterfeit mark combining the characteristic that the image superimposed by gratings and fingerprints is not easy to be shot and imitated and the specificity of the fingerprints, and can be used as anti-counterfeit marks of important passes, employee's cards, files and valuables.
Description
Technical field
The present invention relates to the grating anti-false sign, relate in particular to the anti-false sign that grating technology combines with dactylography.
Background technology
Current anti-false sign is more by imitated incident of forging, and its main cause is that the specificity of sign is relatively poor, makes anti-false sign in order to prevent that forgery from combining with grating technology and dactylography, can increase its imitated difficulty.
Grating is placed on the fingerprint image, when a branch of rayed is on grating, the transparent lines of part light transmission grating are radiated on the following fingerprint image surface, form bright lines, another part rayed is blocked on the black lines of grating, during from top view, the light and shade lines mutual superposition on fingerprint surface shade line bar and the grating forms special superimposed image.The continuous wireless distortion of the shape of this image along with the variation of incident optic angle, thereby be difficult for taking pictures and duplicate.
With plane fingerprint on the paper of printing ink stamp is example, on half of fingerprint pattern, give out light grid, half grid of not giving out light, when irradiation light, there is the grating place superimposed image to occur, the i.e. behavioral characteristics of wireless distortion with the variation of optic angle, then exposing the fingerprint inherent feature at the no-raster place is static nature, and the Changing Pattern that the former can be out of shape with optic angle with special its figure of solid comparison sem observation is with the true and false of identification marker; The latter can observe its specificity with the fingerprint automation recognition instrument, to distinguish true from false.
Summary of the invention
The objective of the invention is to the grating fingerprint antifake mark that above principle is made is the whole anti-false sign that replicability combines that is difficult for fingerprint specificity and superimposed image.
The grating fingerprint antifake mark that grating technology of the present invention and fingerprint combine is characterised in that this sign is made up of original screen panel, finger print image, adhesive sticker three layers, and described original screen panel is that half of surface has the grating streakline, the transparent panel of half no-raster streakline.
The a part of streakline for selecting fingerprint for use that is further characterized in that of anti-false sign of the present invention moves towards with the parallel or approximately parallel fingerprint image of grating streakline.
The present invention compares with prior art, the advantage of grating anti-false sign of the present invention: have dynamically and static two kinds of features, and the corresponding testing instruments and the method for inspection are arranged; Feature is obvious, and check is convenient difficult imitated, and anti-counterfeiting performance is reliable, and particularly the speed of identification is fast automatically, can be used for pass, the employee's card in important place, the anti-false sign of vital document and article.Its thickness is thicker slightly than other anti-false sign.
Description of drawings
Below, with reference to the description of drawings one embodiment of the present invention.
Accompanying drawing 1: be the synoptic diagram of special original screen panel;
Accompanying drawing 2: be the sectional view of grating fingerprint antifake mark;
Accompanying drawing 3: be the characteristics of image synoptic diagram of grating fingerprint antifake mark.
Embodiment
Fig. 1 (a) is depicted as the position of not drawing the grating streakline, and Fig. 1 (b) is depicted as the position that special original screen panel is drawn the grating streakline.The width of grating streakline should be similar to the width of fingerprint line, and the thickness of original screen panel should be less than this width, and original screen panel is made with transparent material.
Among Fig. 2,1 is original screen panel, and 2 is fingerprint image, and the part that should select the fingerprint lines for use is with the parallel or approximately parallel fingerprint of grating streakline: 3 are non-drying glue layer.Original screen panel and fingerprint pattern stacked up coat non-drying glue layer behind the plastic packaging, can finish grating fingerprint antifake mark.
Fig. 3 (c) is depicted as the fingerprint inherent feature.Fig. 3 (d) is depicted as the grating fingerprint superimposed image.
Using method of the present invention is the adhesive sticker face of grating anti-false sign to be attached to intend on the false proof object earlier, can see with natural light or when its surface of light-illuminating of certain distance is arranged: 1. produce the dynamic image grating fingerprint superimposed image of stepless distortion along with the incident light angular variable; 2. can see that the fingerprint inherent feature is a static nature.The former with special three-D comparison sem observation along with optic angle changes the rule of its metamorphosis, to distinguish true from false; The latter can use the fingerprint automation recognition instrument, and its true and false of quick identification also can detect by an unaided eye and distinguish true from false.
Claims (2)
1. the grating fingerprint antifake mark that combines of grating technology and fingerprint, it is characterized in that this sign is made up of original screen panel (1), finger print image (2), adhesive sticker (3) three layers, described original screen panel (1) is that surperficial half has the grating streakline, the transparent panel of half no-raster streakline.
2. anti-false sign as claimed in claim 1 is characterized in that moving towards with the parallel or approximately parallel fingerprint image of grating streakline for a part of streakline of selecting fingerprint for use.
