At present, there is a growing emphasis on safeguarding image data, yet conventional encryption methods are full of numerous limitations. In order to tackle the limitations color methodologies, such as inefficiency and insufficient security, this paper designs an expedited method for images that uses DNA coding in conjunction with multiple chaotic systems. The algorithm proposed based three-dimensional permutation, global scrambling, one-dimensional diffusion coding. First all, permutation algorithms scramble image, which disrupts high correlation among pixels. Second, RSA SHA-256 hashing utilized derive starting value necessary system produce key. Third, encrypted by using scrambling diffusion. Finally, rules used perform computing. experimental results indicate scheme exhibits relatively weak inter-pixel correlation, uniform histogram distribution, information entropy approaching eight. This shows able protect safely efficiently.
