Crypt-IMG: Grayscale Medical Image Encryption Using DNA Encoding and 2D Baker Mapping

The digital age has led to a growing need for secure data transmission and storage, making image encryption techniques crucial. An innovative approach to image encryption combines DNA coding and chaotic mapping to improve security and reliability. The method converts an image into a digital representation, encodes it into a DNA sequence, and processes it using a chaotic map. This creates a random and complex encrypted image, making it difficult for unauthorized access. The experimental and statistical analysis results demonstrate effectiveness against various attacks, including statistical, differential, and brute force. To improve confidentiality, the proposed work contributes to strengthening data security in the digital age and finds applications in secure image transmission, medical imaging, and confidential document storage.
