Joint Watermarking for Image Reliability Control in Encrypted and Compressed Domains

Abstract

Sharing medical images can enormously help doctor in their day by day practice by permitting them to arrive at a symptomatic all the more rapidly. However, such images are sensitive and should be ensured. In this paper, propose the principal joint watermarking-encryption pressure conspire for the insurance of medical images. Its inventiveness is twofold. In a first time, it permits the admittance to watermarking-based security administrations from the scrambled and the compacted bitstreams without parsing them even part of the way. It gets conceivable to follow images and control their dependability from both the encoded and compacted spaces. In a second, it remains on the blend of spot replacement watermarking, JPEG-LS and the AES block figure in its CBC mode to make our plan. Tests directed on various medical images modalities (radiographic and retina pictures) show the ability of our framework to safely make accessible a message in both scrambled and compacted areas while limiting the contortion of the images.
