An Evaluating Scheme for Embedding Security of Natural Language Watermarking
Zhili Chen · Journal of Beijing Electronic Science and Technology Institute · 2009
With the development of Internet,it is easier to get unauthorized digital media than ever before.Natural language watermarking(NLW)is a kind of digital rights management(DRM)techniques specially designed for natural language documents.NLW embeds watermark into documents in linguistic meaning-preserving ways.The previous research on designing elaborate watermarking algorithms,security or quality of these schemes is briefly discussed.In this paper,we propose an evaluating scheme for embedding security of NLW,define ideal undetectability,and design ways to construct an inter-proof system for undetectability against specific detector.We also apply this evaluating scheme to some practical NLW systems.
