In this paper we describe a novel watermarking approach towards contentual watermarking of dynamic webpages which is capable of tracing back the IP address of whom, and the exact time and date when the document in question has been duplicated. The watermarking scheme is non-intrusive, resilient, blind, robust, reversible and suitable for large amounts of textual web-page content. Hereby, we utilize certain UTF-8 entities inserted at syntactically correct places for textual hyphenation.
