Health services are now relying heavily on telecommunications which has opened up a new avenue called tele health services. In this technological aspect, the health related data is stored and shared among remote nodes to facilitate diagnosis and analysis. Robotic surgeries, remote diagnosis and data warehousing are the fundamental avenues where tele health services are needed. This automatically brings about the necessity for security of tele health data specifically image related data. Images are the most widely used data formats shared due to the amount of information they contain. Hence, conventional security measures are now being replaced with multi-layer security techniques for enhanced security. This paper primarily focusses on image encryption based techniques, image steganography based techniques and multi-layer or multi-level hybrid technique. The salient features of previous work done in the domain is also cited. The performance evaluation parameters are also discussed.
