Medical Image Encryption Into Smart Healthcare IOT System

The security and privacy of medical data are highly required when it involved in connecting with smart and intelligent sensor devices in the hospital ecosystem. The Internet of things is mutually integrated with healthcare to produce effective and smart working system but it still needs better security mechanism which can protect patient's privacy. This paper is focusing to protect medical data by using image encryption techniques. In which we are applying three rounds of high-speed scrambling as well as pixel adaptive diffusion concept for shuffling random neighboring pixels. In addition, implementing pixel adaptive diffusion our mechanism is used modulo arithmetic operation. Simulations and experiments demonstrate that the encryption mechanism employing modulo arithmetic operation have comparatively higher levels of security. It can adapt better than several traditional as well as state-of - the-art image encryption.
