Abstract

This paper proposes a Digital Watermarking Algorithm using a unique combination of Discrete Wavelet Transform (DWT), Discrete Fourier Transform (DFT) and Singular Value Decomposition (SVD) for secured transmission of data through watermarking digital color images. The singular values obtained from SVD of DWT+DFT transformed watermark is embedded onto the singular values obtained from SVD of DWT+DFT transformed color image. Experimental results show the promising performance of the proposed algorithm for watermarking. Peak Signal to Noise Ratio (PSNR) values for the watermarked image in the range of 65 to 85 dB and maximum correlation of 0.9998 are achieved.
