Abstract
The invention discloses a method for making a color-changing anti-counterfeiting digital identifier. The method comprises the following steps of: (1) selecting k different colors to form a color sequence C, generating a group of random digital sequence A with n-bit length, and processing the random digital sequence A according to a first algorithm to acquire a binary sequence B; (2) processing all digits in the binary sequence B and the random digital sequence A according to a second algorithm to acquire corresponding binary sequences respectively, performing modulus operation on the acquired binary sequences respectively to acquire color sequence factors of all the digits in A, and taking corresponding colors from the color sequence C; and (3) sequentially printing the corresponding colors of all the digits in A to a product tag or an anti-counterfeiting identifier. According to the invention, color information visible for a customer is added in the traditional digital anti-counterfeiting, so that the anti-counterfeiting strength of the digital anti-counterfeiting can be effectively improved; and the information is difficultly decoded by a fabricator because the fabricator needs to own not only digits but also colors corresponding to all the digits, but the digits per se do not contain the color information.
Description
Technical field
The invention belongs to the method for making in digital false-proof technology field, particularly a kind of color-changing anti-counterfeiting digital identifier.
Background technology
Digital false-proof technology is to be product identification code for each part product generates one group of unique number, should organize digital printing on Product labelling or anti-counterfeiting mark by printing technology, and in the product information of this number correspondence of authentication center computing machine registration, behind the launch, the consumer is sent back to authentication center with the number on Product labelling or the anti-counterfeiting mark and authenticates by being published in phone, note special service number or the network address on Product labelling or the anti-counterfeiting mark.But in practical operation, happen occasionally owing to steal code, the confidence level of digital code anti-false is reduced.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this invention is to provide a kind of method for making of color-changing anti-counterfeiting digital identifier of the false proof intensity that improves digital code anti-false.
Technical scheme: for achieving the above object, the technical solution used in the present invention is a kind of method for making of color-changing anti-counterfeiting digital identifier, comprises the steps:
(1) choose k different color as look order C, k is not less than 2 positive integer; Produce one group of random number code sequence A that the n position is long, n is not less than 5 positive integer, and this random number code sequence A is obtained binary sequence B by the first algorithm;
(2) to each number in the described binary sequence B of step (1) and the random number code sequence A respectively by the second algorithm obtain corresponding binary sequence B1, B2 ..., Bn, and to binary sequence B1, B2 ..., Bn carries out respectively modulo operation: mod (Bx, k)=Bmx, in the formula, x=1,2, n, get Bm1, Bm2 ..., Bmn is as everybody digital look order factor in the random number code sequence A, from look order C, get respectively corresponding color c1, c2 ..., cn.
(3) successively with in the described random number code sequence A everybody digital or wherein the corresponding color of the continuous number more than five print on Product labelling or the anti-counterfeiting mark.
Described k desirable 3 or 4 or 5, preferred 4, can between the user is to the clear identification of color and anti-cracking, obtain preferably balance, the arbitrary integer among the n desirable 12 to 16 like this.
The described color that prints on Product labelling or the anti-counterfeiting mark can the chromatic number code, one of color lump, palace lattice or four kinds of forms of vitta are arranged.
When the user buys product, n figure place code by random number code sequence A on phone, short message or website etc. successively input product label or the anti-counterfeiting mark, background computer is at first inquired about the register information of this random number code sequence A, then reply each digital color information by above-mentioned (1), (2) step as existing, reminding user is checked, only have digital registration to exist and color sequences is consistent is true, otherwise be false.
Beneficial effect: the present invention has added the visual color information of consumer at traditional digital code anti-false, but the false proof intensity of Effective Raise digital code anti-false, so that the fake producer is difficult to crack more, because the fake producer not only will have number, and each digital corresponding color must be arranged, but number itself does not comprise color information.
