Abstract
This paper proposes a kind of wavelet domain image digital watermarking technique using two-dimensional chaotic stream encryption and human visual model. A stream encryption algorithm based on two-dimensional Logistic chaotic map is researched and realized for meaningful grayscale watermarking image. The block embedding intensity is calculated and combined with the human visual model, so that the embedding and detection steps of encrypted binary watermark can be adaptively fulfilled in the wavelet coefficients of the host image. The experimental results have shown that this watermarking technique can endure regular digital image processing and have preferable performance.
