Abstract

Digital watermarking provides authentication, validation and copyright protection for multimedia contents over the internet. Text is the most widely used means of communication in addition to image, audio and video. So it needs to be protected. Text watermarking techniques that have been developed in the past protects the text from illegal copying, imitation, and prevents copyright violations. In this paper, we have proposed an algorithm that ensures the integrity and confidentiality of the document. In this technique, watermark is created on the basis of the contents of the document and embeds it without changing the contents of the document and also encrypts the text to provide confidentiality. To authenticate and prove the integrity of the document the watermark can be easily extracted and verified for tampering.Keywords: confidentiality, integrity, encryption, shuffling, substitution
