- Abstract
- Conventional spatial domain watermarking is effective because watermarks can be applied with minimum visibility effect. However, spatial domain watermarking can be easily be removed through various filters. In this paper, we propose a watermarking method using DCT. It makes watermark by replacing biggest AC component in frequency domain. The objective and subjective experimental results show that proposed algorithm preserve watermark against various attacks.
