Our analysis points out some weaknesses in the watermark techniques currently under SDMI consideration and suggests directions for further improvement. The paper also discusses the framework and strategies for analyzing the robustness and security of watermarking systems as well as the difficulty, uniqueness, and unrealistic expectations of the attack setup JA - Acoustics, Speech, and Signal Processing, 2001.
