With the advent of medical imaging tools and telemedicine technology, the transmission of patient data over the Internet has reduced distance barriers in healthcare delivery. To ensure patient privacy, data is encrypted while being transmitted over an insecure network.In order to overcome the problem of traditional techniques, a self-adaptive image encryption techniques based on multiple maps has been developed. Initially, plain image dependent multiple secret keys are generated for multiple maps. Input image is permuted by N umber of rounds using Arnold cat map. Value of N determined by the secret key. During diffusion process, a random image is generated with the help of 2D Logistic-Sine-Coupling Map (2DLSCM) with another secret key. Finally encrypted image obtained by performing bitwise XOR operation between permuted image and random image. Advantage of proposed multiple chaotic image encryption that incorporates two chaotic maps, Arnold's Cat Map and 2D Logistic Sine Coupling Map (2DLSCM), to improve the randomness and security of encrypted images. It also analyses the performance and security of the scheme and compares it to other known chaotic image encryption schemes.
