| Research Abstract |
Digital watermarking has been proposed as a viable solution to need of copyright protection and authentication of multimedia data. Well-placed watermarks by in recent methods are practically impossible to see. Authors who make art works, however, desire to distribute their own original as it is, and the previous methods cannot satisfy such a requirement. Therefore, this paper proposes a new copyright-protection system, which does not contaminate the original images. The proposed system consists of two functions : signature generation and signature extraction. The both functions do not embed any signatures in the original images. Therefore, by using the proposed system, the owner can distribute his own art works with the copyright-protection. Some simulation results are presented to demonstrate the performance of this system.
