ENCRYPTION OF MEDICAL IMAGE BY APPLYING DNA CRYPTOGRAPHY: A REVIEW PAPER

Abstract

Advanced methods like e-health, smart health, and telemedicine apps are in use in the medical field. Via open-source networks, these techniques transmit a digital medical image. The digital medical image includes patients' confidential and sensitive data. In the remote center, the transmitted digital medical images are used for diagnosis. It is therefore a major concern to provide protection and protect the confidentiality of the medical photo. DNA cryptography and dual hyper chaotic map methods are suggested in this paper to provide a digital medical image with high-level security. The scale of digital medical images is very big and takes more time to compute. The selective digital medical image encryption algorithm is proposed to reduce processing time. The permutation and diffusion method on selected pixels of digital medical images is performed in the proposed cryptosystem. All the DNA encoding rules based on the pixel location of the digital medical image are used to create the DNA structure for digital medical images. By using all DNA decoding rules based on the digital medical image's pixel value, the cypher image is achieved. The cryptosystem proposed is resistant to various forms of attacks.
