A ROBUST DIGITAL WATERMARKING SYSTEM BY SPECIFYING THE EMBEDDED POSITION USING WAVELET TRANSFORM

摘要

In this paper, we propose how to embed the watermarking to an image under the wavelet transform precisely utilizing an appropriate filter for specifying the embedded position and clustering the variance of multi-resolution representation of an image. This system has a feature of the robustness against alteration attacks of malicious users utilizing the precise detection of embedded watermarks.
