摘　　要：将防伪信息采用编码方法写入到产品外包装防伪标识中,实现包装防伪,提出基于激光数字全息技术的产品外包装防伪标识设计方法。构建产品外包装防伪标识的激光数字全息加密密码体系,根据激光数字成像方法,建立产品包装防伪信息中明文数据与密钥之间的关系体系结构,采用密文混沌映射方法,对外观图激光全息图像进行伪随机序列处理,建立产品外包装防伪标识激光数字全息数字加密和编码模型。测试得出,该方法进行产品外包装防伪标识设计的加密、解密和隐藏效果较好,且本方法处理加密图像后得到PSNR的最大值为27.48,提高了产品外包装的防伪能力。The anti-counterfeiting information is written into the anti-counterfeiting logo of product outer packaging by the coding method to realize the anti-counterfeiting of the packaging.A design method of anti-counterfeiting logo of product outer packaging based on laser digital holography technology is proposed.The laser digital holographic encryption cipher system for the anti-counterfeiting identification of the product outer packaging is constructed.According to the laser digital imaging method,the relationship architecture between the plaintext data and the key in the anti-counterfeiting information of the product packaging is established.The ciphertext chaotic mapping method is used to process the pseudo-random sequence of the laser holographic image of the appearance image,and the laser digital holographic digital encryption and coding model of the anti-counterfeiting identification of the product outer packaging is established.The test results show that the method has good encryption,decryption and hidden effects on the anticounterfeiting mark design of the outer packaging of the product,and the maximum value of PSNR obtained by the method after processing the encrypted image is 27.48,which improves the anti-counterfeiting ability of the outer packaging of the product.
