In this paper, we presented a dual secure digital image watermarking algorithm based on Discrete Wavelet Transforms (DWT), Lifting Wavelet Transforms (LWT) and Singular Value Decomposition (SVD) using Genetic Algorithm (GA) for medical images. The natural image is chosen as cover image and is decomposed up to three levels using discrete wavelet transform. The medical image is chosen as a watermark. The GA is used while embed and extract the watermark. The encryption is proposed to be effected using RSA and AES encryption algorithms. A Graphical User Interface (GUI) which enables the user to have ease of operation in loading the image, watermark it, encrypt it and also retrieve the original image whenever necessary is also designed and presented in this paper. Peak signal to noise ratio (PSNR) and normalized correlation coefficient (NC) are computed to measure the image quality of the proposed technique. Experimental results show that the proposed watermarking technique has good imperceptibility and robustness against to salt & pepper noise attack.
