Copyright Protection Scheme of Natural Language Text Using Birthmark
Deyi Li · Jisuanji gongcheng · 2007
To identify the copyright of natural language text effectively,this paper presents a novel scheme to derive birthmark from a text.Since the birthmark is a unique and native characteristic of every text,a text with the same birthmark of another can be easily suspected as a copy.It proposes an application scenario for birthmark,in which birthmark can be used as an effective method to identify the copyright of text.The experiments show that birthmark successfully distinguishes non-copied files and has quite a good tolerance against meaning-preserving attacks.
