Considering both of Spread spectrum and quantization can complement
a hybrid-watermarking model is constructed by integrating spread spectrum with quantization technique.Furthermore
a novel hybrid-watermarking scheme is proposed based on spread spectrum and quantization in multiwavelet domain.The performance analysis is used to describe the interrelations among length of sequence
channel capability
detection error rate and so on.Moreover
the experimental results demonstrate that the proposed algorithm provides the capacity maximization under the precondition of robustness.
