Abstract :
A simple digital watermarking based on integer wavelet transform (IWT) is proposed. Instead of hiding data bits directly to the blocks, we employ adaptive bit-labeling scheme to a block so that it can be used to carry a data bit 0 or 1. Simulations show that the proposed method robustness against manipulations such as JPEG2000, JPEG, cropping, (color) quantization, noise additions, low-pass filtering, (edge) sharpening, brightness, contrast, winding, and inverting.
