Color Image Encryption Algorithm for Medical Image by Mixing Chaotic Maps
Un-Sook Choi, Sung Jin Cho, Sung Won Kang · 2020
Advances in wireless network technologies such as 5G mobile communications and the development of multimedia display devices have made it possible to transfer huge amounts of images over wired and wireless Internet or to store them on third parties. These technologies have removed barriers to distance between patients and medical staff by providing clinical health care at a distance. Also these made it easier to access health services and enabled the transmission of big data such as medical images. Therefore, the necessity of protecting various sensitive information included in the medical image is increasing. In this paper, we propose a color medical image encryption algorithm to secure medical images. The proposed encryption algorithm is based on programmable cellular automata, maximum length cell automata, and Chen chaotic system. Various experiments and statistical analyzes verify the safety of the proposed algorithm.
