Information security has become a requirement these days, there is this highly sensitive data needs to be transmitted securely over networks to prevent data modification. Therefore, the medical images and the specific medical condition of the patient must be kept secure. In this paper, a medical image encryption technique is proposed. This technique uses first a Butterworth High Pass Filter (BHPF) to improve the medical image details to avoid any possible damage during the encryption-decryption method. The proposed technique is then developed by modified Arnold's cat map technique combined with the RC4 (Rivest Cipher 4) algorithm. A comparative study discusses the efficiency of the proposed technique concerning Arnold's Cat Map with AES (Cat-AES). One of the factors used in this paper is the absolute correlation coefficient near zero value to appear uncorrelated between the original image and the encrypted image. the result is shown the correlation coefficient equal zero on 13 from 20 of the brain CT for the proposed technique but CAT-AES is 2 from 20 of CT Brain Image and decreasing both the time of the encryption/decryption process is 35.24 second in the proposed technique and 75.37 second on CAT-AES and energy-efficient without changing the quality of medical images.
