| Abstract: |
| In this paper, the concept of multimedia digital watermark is introduced. The present state of this technology is summarized. The hypothesis test procedures of two different algorithms using DCT are analysed, and threshold choice problem is discussed. Computer simulation is done to confirm the conclusions made. |
