ABSTRACT
Digital text documents have become a significantly important part on the Internet. A large number of users are attracted towards this digital form of text documents. But some security threats also arise concurrently. The digital libraries offer effective ways to access educational materials, government e-documents, financial documents, social media contents and many others. However content authorship and tamper detection of all these digital text documents require special attention. Till now, considerably very few digital watermarking techniques exist for text documents. In this paper, we propose a method for effective watermarking of Hindi language text documents. Hindi stands second among all languages across the world. It has widespread availability of its digital contents of various types. In proposed technique, the watermark is logically embedded in the text using 'swar' (vowel) as a special feature of the Hindi language, supported by suitable encryption. In extraction phase the Certificate Authority (CA) plays an important role in the authorship protection process as a trusted third party. The text is decrypted and watermark is extracted to prove genuine authorship. Our technique has been tested for various types of feasible text attacks with different embedding frequency.
