Medical Image Encryption Algorithm based on Dynamic DNA Sequencing and 2D-3D Chaotic Equations

Abstract

Digital images are now widely used in modern clinic diagnosis. The diagnostic images with confidential information related to patients’ privacy are stored and transmitted via public networks. Secured schemes to guarantee confidentiality of patients’ privacy are becoming more and more vital. Medical images are considered as one of the most important and sensitive data in information systems. Sending medical images over the network requires a strong encryption algorithm such that it is resistant against cryptographic attacks. Among the three security objectives for the security of information systems namely confidentiality, integrity and availability, confidentiality is the most important aspect that need to be taken much care for the secure storage and transmission of medical images. This paper proposes an adaptive medical image encryption algorithm based on Dynamic DNA Sequencing and 2D-3D Chaotic Equations that encrypts any medical image with same uniformity and efficiency.
