A Review on Chaos-based Image Encryption Techniques for Healthcare Applications: Issues and Challenges

Abstract

Due to the rapid growth of communications networks, an increased number of multimedia information has been exchanged through unprotected communications. The multimedia data can be in the form of satellite images, images for the military, images for use in medicine, etc. At current time, telemedicine users are using communication networks to transmit various medical data in the form of images. Every single one of these photographs contains private and confidential information. Security of sensitive data is therefore crucial to preventing unauthorised access. Currently, a number of image encryption techniques allow for the extremely secure storage of medical images. Present chaos-based picture encryption techniques offer a high level of security for protecting medical photos. Reviews of several chaos-based image encryption methods for encrypting medical photos are discussed in this paper. The assessment metrics, results, and comparison analysis of various medical picture encryption systems are also presented in this paper. The field’s future directions are then addressed.
