| Abstract(in English) | Digital watermarking is one of the techniques to protect copyright ownership of digital contents such as images, audio, and video. Watermarking protects copyright ownership by hiding information related to author (watermark) within contents on the condition that it is imperceptible. One of the problems of watermarking is how we increase reliable information of watermark after suffering data compression, signal processing, etc. (information hiding capacity). Moulin formalized watermarking by information theoretic analysis and obtained information hiding capacity. But he didn't calculate it numerically. In this paper, we propose an algorithm to calculate a lower bound of information hiding capacity by changing attacker's assumption in Moulin's model of watermarking. |
