Robust against JPEG compression and color reduction

Achieved high PSNR of 49.63 dB

Does not require original image for watermark extraction

Abstract

Digital watermarking consists on inserting a mark into an image to protect it against copies. The heaviness of the extraction procedure with the old methods urged us to look for a new algorithm in the singular values domain which would be blind : it does not require the original image to extract the mark. We propose a new robust method which consists on inserting the bits of the mark into the singular values matrix. Contrary to most of the watermarking algorithms, it is blind and the results show that our method is robust against the JPEG compression, the reduction of colors (GIF) and the histogram spreading. So, we were able to obtain PSNR = 49,63 dB.
