Design Of Chinese Text Zero-watermarking Algorithm Based On Coreference Resolution

With the rapid development of Internet technology,communication through the network platform has become normal.It presents mostly in text form,but the text information is most likely to be lossless copy.So the copyright protection of the text has aroused widespread concern,and text digital watermarking technology is one of the effective ways to solve such problems.According to the existing watermarking scheme is too general and not limited to the genre of text,this paper designed and constructed a text zero-watermarking scheme based on coreference resolution,the main work includes the following aspects:(1)Based on the analysis of the existing text watermarking scheme,a chinese text zero-watermarking scheme based on coreference resolution is designed.The scheme includes text preprocessing,zero-watermarking construction,zero-watermarking detection and other components.(2)In the preprocessing part,the processing flow of text preprocessing is designed,and the algorithm of text segmentation,sentence position information statistics,extraction of the first word set and three-dimensional model(segment,sentence,word)construction is designed and implemented.(3)In the part of zero-watermarking construction,the watermarking process based on coreference resolution is given,and the algorithm of generating the feature noun set,the chinese character to Pinyin,and the coreference resolution based on attribute matching,are designed and implemented in detail.(4)In the zero-watermarking detection part,the watermarking copyright decision process based on coreference resolution is designed,and the algorithm of decrypting,feature reduction,zero-watermarking similarity calculation and copyright judgment is designed and implemented.(5)The performance of this scheme is analyzed from the aspects of robustness and adaptability.The results show that the proposed scheme has better pertinence and adaptability to the narrative as the theme of the text.
