| Abstract: | Through analyzing the embed procedure of digital watermarking based on DCT, proposes a new robust algorithm that embedding watermarking in DCT domain. The experimental result shows that the algorithm can resist attack of the including compressing, noising, cutting and medium filtering, it has better ability resist the geometry attack. |
