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...
