Siddaiah Journal on Image Processing 2349-6827 2 1 19 27 Medical Image, Discrete Wavelet Transform, Singular Value Decomposition, Genetic Algorithm, Multi Objective Optimization, Encryption Watermarking secures the integrity of the medical images and has been used. One specific limitation for the methods that can be used in water marking medical images is that water marking procedure should not result in degradation of the image. In this work, a dual security approach comprising water marking and encryption is implemented to provide authenticity and protect the integrity of the medical image. A multi objective optimization function that can preserve the structural integrity of the medical image while maintaining robustness and imperceptibility is formulated. Genetic Algorithm (GA) optimization approach is used to optimize the multi objective function. The water mark is implemented using hybrid approach comprising Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD). The encryption is affected using RSA & AES encryption algorithms. A graphical user interface (GUI) is designed to present the proposed approach in the form of usable tool to help the user in the embedding and extracting process. The water mark is subjected to different types of noise attacks and its robustness and integrity are tested. January - March 2015 Copyright © 2015 i-manager publications.
