Hybrid watermarking scheme based on fast walsh-hadamard transform and singular value decomposition using parity function

Digital image watermarking is a useful solution to the problem of information security, copyright and network security. This paper shows a new scheme for robust and high rate embedding of watermarks into digital images using Fast Walsh Hadamard Transform (FWHT) and singular value decomposition (SVD). The proposed technique consists of five steps. The main features of the proposed method are its simplicity, Elasticity in data embedding capacity. The experimental results executed using MATLAB software and it showed good performance, imperceptibility for the watermark and security for the embedding data in comparison with some of the recently existing techniques. It showed also robustness against the most common attacks such as salt and pepper noise insertion attack, JPEG compression, cropping, rotation, resizing, average filtering, Gaussian filtering, motion-blur filter and histogram equalization.
