Anti-counterfeiting Design and Identification Method of Logistics Goods Outer Packaging Based on Laser Molding Holographic Technology
In order to improve the anti-counterfeiting ability of logistics goods outer packaging,this paper proposes the research on anti-counterfeiting identification of logistics goods outer packaging based on laser molding holographic technology.It encodes the anti-counterfeiting image by laser molding holographic encryption technology,combines the piecewise linear mapping to extract encryption feature quantity,and combines with the random number or key to generate the Hyperhenon initial value.It uses the Hyperhenon value to perform pixel replacement and shift operations on the anti-counterfeiting image,so as to enhance the encryption effect.The experimental results show that the image encryption performance of the anti-counterfeiting identification of logistics goods outer packaging using this method is good.The encryption correlation of anti-counterfeiting logo is 0.92,and the anti-counterfeiting and anti-attack ability is strong.The average recognition accuracy rate of identifying 10 kinds of different sizes of anti-counterfeiting logo of logistics goods outer packaging is 97%,and the recognition accuracy is high.
