Generally, the wavelet transform is applied for watermarking, where a whole
image is transformed to the frequency domain. However, many schemes which
adopt the wavelet transform are weak for StirMark attack designed to affect
locally such as rotation, extension, reduction, etc. In this paper, we pro
pose a new scheme which applies the wavelet transform locally and has a tol
erance for StirMark attack. How to maintain the quality of the watermarked
image is also shown.
