Abstract

The rapid development of telemedicine services and the requirements for exchanging medical information between physicians, consultants, and health institutions have made the protection of patients’ information an important priority for any future e-health system. The protection of medical information, including the cover (i.e. medical image), has a specificity that slightly differs from the requirements for protecting other information. It is necessary to preserve the cover greatly due to its importance on the reception side as medical staff use this information to provide a diagnosis to save a patient's life. If the cover is tampered with, this leads to failure in achieving the goal of telemedicine. Therefore, this work provides an investigation of information security techniques in medical imaging, focusing on security goals. Encrypting a message before hiding them gives an extra layer of security, and thus, will provide an excellent solution to protect the sensitive information of patients during the sharing of medical information. Medical image steganography is a special case of image steganography, while Digital Imaging and Communications in Medicine (DICOM) is the backbone of all medical imaging divisions, whereby it is most broadly used to store and transmit medical images. The main objective of this study is to provide a general idea of what Least Significant Bit-based (LSB) steganography techniques have achieved in medical images.

Highlights

Safe communication is one of the big challenges that has emerged with great progressions in communication technologies, especially in the field of information exchange, which requires protection [1]
The basic purpose of this study is to present a comprehensive review of what Least Significant Bit-based (LSB) steganography techniques have achieved in medical images domain
In order to achieve confidentiality and security in the sharing of patient information in telemedicine applications, medical image steganography requires an emphasis on other essential criteria, such as privacy and authentication

Summary

Introduction

Safe communication is one of the big challenges that has emerged with great progressions in communication technologies, especially in the field of information exchange, which requires protection [1]. These progressions have imparted numerous advantages; at the same time, there are several risks and hazards that need to be considered as well. The advancement of information and communication technologies (ICT) and their gradual adoption by healthcare providers have enhanced the knowledge of diseases and therapies, communication between practitioners, workflow, and efficiency of processes, and generally allowed high-quality services to be provided [2]. Telemedicine is the utilisation of ICT to provide clinical healthcare from remote places. According to the definition by the American Hospital Association (AHA), the word ‘telemedicine’ starts with the Greek prefix ‘tele’, which means distance, as well as the meaning of the whole word ‘telemedicine’, which refers to is remote medicine [4,5]
