In this paper an attack model of text watermarking is proposed based on communication model, and three different assumptions are made to attackers’ actual ability. According to the related research result of digital watermarking theory, the important watermarking properties which influence watermarking robustness and security are analyzed, and then text watermarking robustness and security are ...

In this paper we discuss natural language watermarking, which uses the structure of the sentence constituents in natural language text in order to insert a watermark. This approach is different from techniques, collectively referred to as “text watermarking,” which embed information by modifying the appearance of text elements, such as lines, words, or characters. We provide a survey of the cur...

The using of the internet with its technologies and applications have been increased rapidly. So, protecting the text from illegal use is too needed . Text watermarking is used for this purpose. Arabic text has many characteristics such existing of diacritics , kashida (extension character) and points above or under its letters .Each of Arabic letters can take different shapes with different Un...

This paper presents the high-capacity blind text watermarking algorithm that is robust to print and scan operations and this method based on the odd-even quantization. First, segment the binary images of Chinese text characters. And the text image is segmented into the embedded part, adjust part, and dislodge part. After segmentation, the quantization function is built on the basis of invariabl...

A novel text watermarking algorithm is presented. It combines natural language watermarking and Chinese syntax based on BP neural networks. Since the watermarking signals are embedded into some Chinese syntactic structure rather than the appearance of text elements, the algorithm is totally based on the content that can prove to be very resilient. It will play an important role in protecting th...

Data hiding into text documents itself involves pretty complexities due to the nature of text documents. A robust text watermarking scheme targeting an object based environment is presented in this research. The heart of the proposed solution describes the concept of watermarking an object based text document where each and every text string is entertained as a separate object having its own se...

Copyright protection and authentication of digital contents has become a significant issue in the current digital epoch with efficient communication mediums such as internet. Plain text is the rampantly used medium used over the internet for information exchange and it is very crucial to verify the authenticity of information. There are very limited techniques available for plain text watermark...
