【摘要】 针对电子保单系统中信息载体QR二维码的保密以及防伪鉴别问题,论文提出了基于AES加密算法结合随机生成初始密钥的加密方法对原始信息加密进而编码生成QR二维码,再嵌入数字水印进行防伪鉴别。嵌入数字水印采用基于Logistic混沌映射算法在空域将水印嵌入QR二维码。最后通过相应试验对加密和数字水印算法进行了分析评价。试验和分析结果表明,论文设计的加密和数字水印嵌入算法具有可行性和可操作性,提高了电子保单QR二维码信息的安全性能和防伪性能。更多还原

【Abstract】 In view of the existed problems of information secrecy carried by QR code and anti-counterfeiting identification in electronic policy system,a method was proposed in this paper based on AES encryption algorithm combined with randomly generated initial key on the original information encryption to generate QR code.Then a digital watermark was embedded into the QR code,which was ground on Logistic chaotic mapping algorithm.Test and analysis results showed that the design of the encryption and digital watermarking embedding algorithm is was feasible and maneuverable,improved the electronic policy QR code information safety and security performance.更多还原
