This paper explains and analyzes the successful attacks submitted by the authors on four audio watermark proposals during a 3-week SDMI public challenge. 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.
