Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 It is a dot matrix anti-counterfeiting code based on chaotic encryption generated by the present invention. The upper left, upper right, and lower left units are positioning units, the lower right corner is an auxiliary positioning unit, and the rest are data units.

[0022] figure 2 It is the process of chaotic encryption, and its specific process is as follows:

[0023] (1) Convert the encoded 01 binary sequence into a group of eight bits, convert it into an integer array, and then arrange the array into a data matrix from left to right and from top to bottom, with the number of rows R and the number of columns C as much as possible near.

[0024] (2) Using three different sets of initial values ​​and control parameters, namely figure 2 u in 0 , x 0 , u 1 , x 1 , u 2 , x 2 , generate three different sets of chaoti...

Abstract

The invention discloses a chaotic encryption-based lattice anti-fake code design method and an application system thereof. According to the method and the application system, the safety of lattice anti-fake codes is improved by utilizing a chaotic encryption technology, and chaotic encryption sequences are generated by using a worm population model and different initial values and control parameters so as to be applied to the diffusion and scrambling processes of chaotic encryption. According to the method and the application system, a ciphertext of a designed is as long as a plaintext, concise, efficient, high in encryption speed and suitable for commercialized production. The invention furthermore discloses the chaotic encryption-based lattice anti-fake code application system. Accordingto the method and the application system, a counter method is utilized to fill the gap that lattice anti-fake codes cannot resist scanning-counterfeiting attack, and a decryption function is deployedat a server, so that the pressure of an android app client is lightened, benefit is brought to the relative independence of the server, passwords are not easy to leak and the safety coefficient is relatively high.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting marks, and in particular relates to a chaotic encryption-based lattice anti-counterfeiting code design method and an application system thereof. Background technique [0002] Traditional anti-counterfeiting marking technologies mainly include laser holographic anti-counterfeiting, special ink anti-counterfeiting, engraved gravure printing anti-counterfeiting, RFID anti-counterfeiting, telephone anti-counterfeiting, and QR code anti-counterfeiting and other technologies. These anti-counterfeiting technologies have their own advantages, but they also have their own shortcomings. Although laser holographic anti-counterfeiting and ink anti-counterfeiting are very mature, low in cost, and relatively friendly to consumers in use, their anti-counterfeiting effects are poor due to their low technical content and easy imitation; The same is true for RFID; telephone anti-counterfeiting has beco...
