Encryption algorithm using non-integer order chaotic systems in medical images

Abstract

One of the most efficient techniques to protect medical images is to apply algorithms based on nonlinear dynamics. This paper presents an encryption and compression scheme for medical images. The scheme is based on fractional-order chaotic systems, combined with a discrete wavelet transform compression. The encryption performs digital cycle operations between the solutions of the dynamic system and the image to be encrypted, adding the characteristics of confusion and diffusion to the image. The experimental results and statistical analyzes show adequate performance for application in medical imaging in the presence of multiple seizures and noise.
