Resource optimized Region Based Image Encryption Using Chaotic Maps

Introduction

Telemedicine has been expanding to numerous sectors of health care systems and fields, including dermatology, cardiology, and neurology, since its inception in the 1960s. It provides a variety of benefits to the community, including improved and faster diagnosis, decreased consultation and treatment costs for patients, and more. Various diagnostic information about the patient is collected and sent among medical practitioners and patients for optimal care and treatment, ranging from cardiovascular readings to x-rays and ultrasound scan results. These bits of information should only be accessible to authorized persons in order to protect patients' privacy and respect medical practitioners' ethics. These diagnostic data, on the other hand, are typically transmitted over a public network, raising the risk of data leakage to unauthorized parties or adversaries. As a result, appropriate protection for data stored and in transit is required. Medical images captured during various medical procedures are very fragile and the number of security-related issues when sending over an unsecured network. Complicated Cryptographic algorithms are typically used to secure the transmission of medical images. In fact, Time diagnosis and image encryption time should be as short as possible. However, resources limited devices cannot perform complex encryption processes due to limited battery life and limited processing options. Therefore, encryption is outsourced to a third party such as the cloud. Much work has been done.
