Utilize separated graphics random incorporation to carry out false proof method and realization
The present invention relates to field of anti-counterfeit technology, relate in particular to a kind of anti-counterfeiting technology of random figure identification comparison.
In field of anti-counterfeit technology, generally adopt bar code Quick Response Code, laser mark, texture anti-fake label etc. at present.These prior aries all have problems:
1, bar code anti-counterfeit or phone sequence number are false proof, although cost is lower, hold very much imitated.And regular phone or network inquiry preset first inquiry of hypothesis for genuine piece user also science not itself, suppose to be divorced from reality;
2, false proof, scanning Quick Response Code, the texture anti-fake label of laser mark or other printing technologies are false proof, and not only cost is high, and owing to being once to generate fixing false proof figure, are easy to stolenly, make to occur repeatedly that false commodity paste the difficult situation of true anti-counterfeiting label.Even if true anti-false sign is not stolen in addition, the nuance of false anti-false sign and true anti-false sign makes user also be difficult to identification.
3, RFID is false proof, and commodity conjugation is poor, and anti-fake material cost is high.The rfid card of lower price is easy to be replicated very much, and the true and false needs RFID card-reading apparatus while detection, very inconvenient to ordinary consumer.
Summary of the invention:
The object of the invention is to, design a kind of separated graphics random incorporation of utilizing and carry out false proof method, and implementation step, address the above problem.
To achieve these goals, the technical solution used in the present invention is as follows:
Technical solution of the present invention is divided into random anti-counterfeit figure generative process and anti-counterfeit recognition comparison process.
Random anti-counterfeit figure generative process:
1, at detected material (can be that commodity packaging can be also commodity itself or the false proof object of other needs) upper printing one or more fixing figure (A1, A2, A3 ...);
2, at fixing figure (A1, A2, A3 ...) in arbitrarily random site paste one or more random figures (B1, B2, B3 ...), thereby form random anti-counterfeit figure;
3, record and extract random figure in random anti-counterfeit figure (B1, B2, B3 by shooting or scanning device ...) relatively fix figure (A1, A2, A3 ...) position, angle, and the feature of the random anti-counterfeit figure forming itself, and will after these feature digitizings, deposit database in.
Anti-counterfeit recognition comparison process:
1, by shooting or scanning device, random anti-counterfeit figure is identified, produced digitized result;
2, the digitalized signature data that exist in the result producing and database are compared, and discern the false from the genuine by similarity.
Brief description of the drawings:
Fig. 1 is one of embodiment of the present invention: a fixing figure and a random figure combine;
Fig. 2 is one of embodiment of the present invention: a fixing figure and two random figures combine;
Fig. 3 is one of embodiment of the present invention: a fixing figure and three random figures combine.
In order to make technical matters solved by the invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The separated graphics random incorporation of utilizing is as shown in Figure 1 carried out a kind of embodiment of false proof method.Comprise fixing figure A and random figure B, and formed a complete random anti-counterfeit figure by A and B combination;
Fixing figure A is placed on detected material (can be that commodity packaging can be also commodity itself or the false proof object of other needs) in advance, can adopt printing, paste, welds etc. means;
Random figure B is among the fixing figure A of being placed in of completely random, can adopt equally printing, pastes, the means such as welding;
Afterwards the random anti-counterfeit figure of fixing figure A and the formation of random figure B common combination is taken or scanned, extract the digitalized signature of random figure B with respect to position, angle and the common random anti-counterfeit figure forming of fixing figure A;
Due on detected material (can be that commodity packaging can be also commodity itself or the false proof object of other needs), random figure B is among the fixing figure A of being placed in of completely random, so the digitalized signature of its generation is also completely random.Coordinate the information such as commodity lot number, date of manufacture, realized antiforge function completely.
As shown in Figure 2 and Figure 3, exceed a random figure, implementation step is identical with Fig. 1.
More than by the detailed description of concrete and preferred embodiment the present invention; but those skilled in the art should be understood that; the present invention is not limited to the above embodiment; within the spirit and principles in the present invention all; any amendment of doing, be equal to replacement etc., within protection scope of the present invention all should be included in.
1, be easy to produce: producer can be upper by manually directly B being attached to A on a small scale, produces randomness.Random OEM can be simulated with OEM machine by large producer.
2, with low cost: without printing the high anti-fake card of price.Material cost of labor is substantially negligible.3, be easy to produce and be difficult to copy, fake producer is difficult to copy the state such as graph position and angle and the information that in production run, arbitrarily produce at random, make fraud difficulty and the cost of single product very high, because the anti-counterfeiting characteristic of every genuine piece is not identical, fake in batches more without possibility.
4, science, the anti-counterfeiting characteristic data repetition rate of coding is extremely low, test code not using test code successively with number of times as true and false foundation.
5, user's query script is simple and convenient: only need, by the special APP program scanning of mobile phone image, under arrowband networking state, can complete checking work, and convenient and swift.
6, the assembled state of astronomical figure level, the repetition rate of coding is extremely low, guarantees uniqueness, even if because scanning computational accuracy or magnanimity commodity produce repeated code, also can relend help product ID, date, batch etc. information guarantee uniqueness.
7, utilize ripe summary image recognition technology, application realizes simple, with low cost.
8, attractive in appearance, false proof figure can design in conjunction with color, the trade mark etc. of commodity, in style, can combine together with anti-counterfeit commodities.
