Abstract
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.
