A Novel Scheme for Watermarking Natural Language Text

Abstract

This paper focuses on a novel scheme for watermarking natural language text. It is to use Spread Spectrum Technique to spread the watermarks over the entire text via various synonym substitutions. We give a feasible implementation of synonym substitution using English WordNet, and conducts experiments on it. From the experimental results, we come to the conclusion that this scheme provides a high level of resilience to meaning-preserving attacks.

A Robust Audio Aggregate Zero-Watermark Algorithm

“…The proposed algorithm in this paper produce the watermark Cloud drops by using their own audio features, can make audio files and Cloud model combine deeply together, is more superior than algorithm in [8][9]. Both theoretical analysis and experimental results demonstrate the superiority of the proposed algorithm.…”

“…In [8][9], the authors use subjective human experience to set parameters, and then produce Cloud drops by these parameters. The proposed algorithm in this paper produce the watermark Cloud drops by using their own audio features, can make audio files and Cloud model combine deeply together, is more superior than algorithm in [8][9].…”
