Abstract - Image encryption stands as a vital safeguard for securing sensitive visual information in the modern digital landscape. In the current digital era, image encryption is a crucial precaution for protecting sensitive visual data. In order to increase security and effectiveness, this research presents a novel image encryption method that combines chaotic maps and DNA encoding. The image is first converted into a binary format and then encoded using DNA principles in the suggested method, adding complexity and security. A chaotic key-stream is produced by using chaotic maps, which are renowned for their sensitivity to initial conditions and capacity to produce pseudo-random sequences. The visual data is then effectively scrambled by applying this key-stream to permutation and diffusion operations at the pixel level. The combination of chaotic maps and DNA encoding enables strong defense against multiple attackers while retaining computing efficiency.
