Abstract :
In this paper, a digital image watermarking technique based on discrete wavelet transform (DWT) will be proposed. This scheme is designed utilizing principles deriving from the human visual system, JPEG standard compression algorithm and DWT decomposition. It is optimized special for against JPEG compression. The watermark signal as a binary sequence is embedded to the diagonal higher frequency band at 2-D level DWT decomposition of Y channel in YUV color model. The experiment shows that the proposed scheme has strong robust to against JPEG compression, some popular filtering and geometrical attacks.
