Abstract

In this paper, we propose a blind watermarking scheme using the properties of wavelet coefficient sign. We found it through some experiments that the wavelet coefficient sign is robust against lossy compression methods such as JPEG and JPEG-2000. So we tried to change the characteristic along sub-blocks which decided in advance for watermark insertion. Also, because the proposed algorithm uses the Daubechies 9-tap/7-tap wavelet filter bank, it can be applied to JPEG-2000 lossy compression process directly. Various attacks were given to demonstrate the robustness of the proposed technique.
