Abstract

Digital watermarking provides authentication and protection for multimedia contents over the internet. In addition to image, audio, and video, now a day’s text is the most important medium traveling over the internet. Hence it needs to be protected. Text watermarking techniques that have been developed in past protects the text from illegal copying, forgery, and prevents copyright violations. In this paper, we propose a new text watermarking technique that uses combined image and text watermark and encryption to protect the text document. The watermark is logically embedded in the text and the text is encrypted. Later the text is decrypted and then the watermark is extracted to prove authenticity.
