Abstract：This paper proposed a wavelet tree-quantization readable watermarking algorithm based on chaotic mapping and human visual system. In the algorithm, the watermark is a meaningful binary bitmap and is modulated by a chaotic sequence before embedding. By analyzing the tree structure relation of wavelet coefficients and the model of human visual system, each watermark bit is embedded using two wavelet trees of host image, the trees are so quantized that they exhibit a large enough statistical difference which will later be used for watermark extraction and the watermarking detection needs no host image and original watermark.
