Abstract

Medical image content authentication is very important, since medical image contents are more and more widely distributed. Reversible watermarking becomes a promising technique to embed the information into medical images. In this paper, we define the Region of Interest (ROI) in an image and trying to embed data in Region of Non Interest. When medical image shared through network, for the compression purpose we proposed the JPEG2000 algorithm and to improve the integrity and Authenticity hash value of the image is found by using MD5 and encrypted using RSA to form the DS (Digital Signature). DS and patient information is embedded into DICOM images. Strict authentication can be achieved by providing high security in accessing the secured medical images by medical experts which are available in the websites using Kerberos technique. The proposed method has been tested against various geometrical attacks to verity the robustness of the medical image and it has yields the fruitful results.
