基于混沌理论和DNA序列运算的古籍数字化版权保护及实现

Digital Copyright Protection and Implementation of Ancient Books Based on Chaos Theory and DNA Sequence Computing

[目的/意义]旨在更好解决古籍高清数字化图像在互联网上传播后存在的版权和高仿真复制问题,提出基于混沌理论和DNA序列运算的加密算法。[方法/过程]该算法以混沌理论为基础,结合DNA序列运算,对图像数据进行像素值替代扩散,再通过图像置乱替换像素值位置,完成整个加密过程。[结果/结论]测试结果表明,该算法加解密效果良好,能够解决古籍高清数字化图像的版权和非法高仿真复制问题。

[Purpose/significance]The paper is to solve the copyright and high simulation problems that exist after the high-definition digitized images of ancient books are distributed on the Internet,and propose an encryption algorithm based on chaos theory and DNA sequence operations.[Method/process]The algorithm is based on chaos theory,combines with DNA sequence operation,performs pixel value substitution diffusion on image data,and then replaces pixel value positions by image dislocation to complete the whole encryption process.[Result/conclusion]The test results show that the algorithm has good encryption and decryption effects,and can solve the copyright and high-simulation reproduction problems of high-definition digitized images of ancient books.
