| Abstract(in English) | In general, watermark information is embedded into the host signals selected from digital content according to a secret key. However, the selected host signals can be easily classified from given watermarked content if all algorithms except for the secret key are in public based on the Kerckhoffs' principle. One of the countermeasures was proposed in ICIP2015 that introduced a simple obfuscating operation. The drawback of the method is the redundancy in the entire watermarking process. Although an alternative method was also presented by the identification of the process, the robustness against attack was decreased in the experiment. In this study, we analyze the reason of the degradation of the performance, and confirm the effects of some signal processing operations in the watermarking process including the obfuscating operation. |
