This paper presents a hybrid digital image watermarking based on DiscreteWavelet Transform (DWT), Discrete Cosine Transform (DCT) and Singular ValueDecomposition (SVD) in a zigzag order. From DWT we choose the high band toembed the watermark that facilities to add more information, gives moreinvisibility and robustness against some attacks. Such as geometric attack.Zigzag method is applied to map DCT coefficients into four quadrants thatrepresent low, mid and high bands. Finally, SVD is applied to each quadrant.
