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

Due to the rapid growth of communications networks, an increased amount 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 the 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, several 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 photographs. Reviews of several chaos-based image encryption methods for encrypting medical photographs 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.
