Proposed a new model based on quantitative jitter and packet-coded blind digital image watermarking algorithm, the algorithm first DWT (Discrete Wavelet Transform) and second layer of randomly selected sub-band IF the corresponding absolute value of the location of the largest coefficient watermark embedded interval, the wavelet coefficients to quantify and in accordance with principles of generating the pre-embedded block coding mode, and then a binary watermark image embedded in them patterns.
