A Security Technique for Authentication and Security of Medical Images in Health Information Systems

Medical images stored in health information systems, cloud or other systems are of key importance. Privacy and security needs to be guaranteed for such images through encryption and authentication processes. Encrypted and watermarked images in this domain needed to be reversible so that the plain image operated on in the encryption and watermarking process can be fully recoverable due to the sensitivity of the data conveyed in medical images. In this paper, we proposed a fully recoverable encrypted and watermarked image processing technique for the security of medical images in health information systems. The approach is used to authenticate and secure the medical images. Our results showed to be very effective and reliable for fully recoverable images.
