A Hybrid Domain Medical Image Encryption Scheme Using URUK and WAM Chaotic Maps with Wavelet – Fourier Transforms

Image encryption is one of the most important techniques to maintain data confidentiality against illegal access and fraudulent usage. In this study, a new medical image technique was developed by combining discrete wavelet transform, fast Fourier Arnold two multidimensional chaotic systems. The subjected transform before magic square shuffles sub-bands. Confusion operations are performed on each scrambled subdomain using Uruk 4D system. To increase randomness unpredictability, second stage confusion implemented in domain Fast transform. final encrypted obtained utilizing secret keys derived from WAM 3D particular, initial conditions for systems grayscale values, thereby increasing algorithm’s sensitivity input image. results tests security analysis indicate that proposed algorithm exceptionally reliable secure.
