Region of interest based selective medical image encryption using multi Chaotic system

As of late, numerous fraudulent assaults towards life/medical coverage's by giving fake wellbeing data are in increment. Hence forth there is a requirement for security of the images sent by the medical expert to the insurance provider. This examination proposes a chaos-based image encryption conspire utilizing Lorentz map and Logistic condition with numerous levels of diffusion. The Lorentz map is utilized for confusion and the Logistic condition for diffusion, in this work, stenography and encryption systems are joined to ensure the patient secrecy, and increment the security in medicinal images. This encryption calculation has high key space, entropy near eight (for dim images) and less relationship among nearby pixels.
