Abstract :
In this manuscript stationary wavelet transform based digital image watermarking algorithm is proposed. The proposed algorithm combines the information of low frequency SWT coefficients and the watermark image without any change in the information present in the original image. Key is combination and is used to extract the watermark. The proposed method will not affect the quality of the image because of no change in the information present in the original image. The simulation results demonstrate the effectiveness of the proposed algorithm.
