Abstract
The invention discloses a 3D star array anti-counterfeiting code generation method, which comprises the following steps: carrying out format conversion on a product protection ciphertext to enable the ciphertext to be converted into an encrypted 3D digital watermark; enabling the encrypted 3D digital watermark to form a 3D star array having eight fixed points and twelve edges through a scrambling algorithm; and adding a key to the 3D star array to form a 3D star array anti-counterfeiting code. The 3D star array anti-counterfeiting code is formed through the 3D digital watermark encryption and scrambling technology; through the scrambling algorithm, the unique key of the required product can be customized personally, thereby ensuring authenticity detection accuracy, and achieving a real-sense three-dimensional anti-counterfeiting strategy; and detection can be carried out only by using a special 3D scanner, thereby expanding 3D anti-counterfeiting code application space.
Description
Technical field
The present invention relates to security code, particularly relate to a kind of generation method of 3D star battle array security code.
Background technology
Currently a popular false proof mode includes that laser anti-counterfeit, telephone service, new material are false proof and it is false proof to utilize RFID to carry out.Wherein the false proof effective property of new material, is the most just copied by people；Laser anti-counterfeit and telephone service cannot function as the mark of commodity, the true and false of this label can only be ensured to a certain extent, can not utilize it that in the information of each field of circulation, commodity are carried out record, therefore its antifalse effect is the most limited, market has had substantial amounts of counterfeit goods stick so-called laser anti-counterfeit label, telephone service label fascination consumer；RFID label tag is owing to being difficult to imitated and can be a kind of tighter false proof mode as the mark of commodity, but there is also the problems such as sticker price is too high, inspection is inconvenient.In addition, these counterfeit protection measures also have a common feature, do not have universality, the initiative that the most easy excitated consumer is false proof, are also difficult to form everybody and all carry out false proof overall situation.Fast development along with technology; progressively occur in that 3D security code; but existing so-called 3D is false proof; it is substantially the strategies such as laser anti-counterfeit; 3 D stereo counterfeit-deterrent strategies the most truly; partial 3-D method for anti-counterfeit, the main strategy being still two-dimensional bar relied on, it is impossible to meet the demand that the commercial 3D printing market developed rapidly is protected for knowledge copyright.Therefore, prior art needs further improvement and develops.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of generation method of 3D star battle array security code.
For solving above-mentioned technical problem, the present invention program includes:
A kind of generation method of 3D star battle array security code; it comprises the following steps: format conversion according to product protection ciphertext; ciphertext is converted into encryption 3D digital watermarking; encryption 3D digital watermarking forms eight fixed points and the 3D star battle array on 12 limits by 3D scrambling algorithm, and forms 3D star battle array security code to 3D star battle array interpolation key Key.
Described generation method, wherein, is printed above-mentioned 3D star battle array security code by the 3D printer of double shower nozzles, and is detected by special 3D scanning detector, if detecting successfully, then this 3D star battle array security code is used for corresponding product, and preserves counterpart keys Key.
The generation method of a kind of 3D star battle array security code that the present invention provides, 3D digital watermarking is utilized to encrypt Chaotic Technology, make 3D star battle array security code, and need product unique key key by scrambling algorithm is personalized, ensure that the accuracy of its detection true and false, reach 3 D stereo counterfeit-deterrent strategies truly, only use special 3D scanner just can detect, expanded the application space of 3D security code.
Accompanying drawing explanation
Fig. 1 is the schematic diagram generating method in the present invention.
Detailed description of the invention
The invention provides a kind of generation method of 3D star battle array security code, for making the purpose of the present invention, technical scheme and effect clearer, clear and definite, the present invention is described in more detail below.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 invention provides a kind of generation method of 3D star battle array security code; as shown in Figure 1; it comprises the following steps: format conversion according to product protection ciphertext; ciphertext is converted into encryption 3D digital watermarking; encryption 3D digital watermarking forms eight fixed points and the 3D star battle array on 12 limits by 3D scrambling algorithm, and forms 3D star battle array security code to 3D star battle array interpolation key Key.
Further, above-mentioned 3D star battle array security code is printed by the 3D printer of double shower nozzles, and is detected by special 3D scanning detector, if detecting successfully, then this 3D star battle array security code is used for corresponding product, and preserves counterpart keys Key.
Certainly; only presently preferred embodiments of the present invention described above; the present invention is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the teaching of this specification; the all equivalents made substitute, obvious variant, within all falling within the essential scope of this specification, ought to be protected by the present invention.
Claims (2)
1. the generation method of a 3D star battle array security code; it comprises the following steps: format conversion according to product protection ciphertext; ciphertext is converted into encryption 3D digital watermarking; encryption 3D digital watermarking forms eight fixed points and the 3D star battle array on 12 limits by 3D scrambling algorithm, and forms 3D star battle array security code to 3D star battle array interpolation key Key.
