Lexical active attack on chaotic text zero-watermarking
He Lu · Journal of Computer Applications · 2012
The conventional steganalysis techniques does not work in zero-watermarking technology because it does not modify carrier text.However,active attack model on text zero-watermarking has not been well studied.In order to solve this problem,an active attack algorithm for text zero-watermarking was proposed.Making use of synonym substitution technology,sync-attack and birthday-attack were defined.Through combining the two active attack methods,a lexical active attack algorithm on text zero-watermarking was designed and implemented.The experimental result shows the proposed algorithm can effectively destroy zero-watermarking without modifying carrier text massively.
