| Research Abstract |
We constructed a criteria on security of digital watermark, and researched digital watermarking schemes which can open the algorithm up to the public. The first result is having developed an evaluation tool of digital watermarking to use as a criteria on security of digital watermark. This tool can perform efficient and unific evaluation. The second result is a classification of digital watermarking according to applications and some digital watermarking schemes which can open the algorithm up to the public such as paper document watermarking, visible watermarking and reversible watermarking. These results can be used as the first step of the discussion on algorithm standardization or public presentation for digital watermarking.
