| 摘 要： | Watermarking system is a complex system requiring both expertise and specialized techniques with security concerns.Thus to relieve the multimedia manufacturers of the complexities of designing complicated watermarking systems, this paper presents a new watermarking model in which watermarking is provided as a kind of service by the specialized watermarking companies. In order to make this service model work, a simple permutation scheme to hide the true contents is proposed. The paper also proves the security of the scheme against the attacks from the watermarking companies. Finally, the effectiveness of the scheme is demonstrated through experiments.
