There have been pressing needs for securing a document and its content, either in electronic form or printed form. This is because counterfeiting and forgeries are extremely widespread all over the world, causing tremendous damage to individuals, industries, societies, and even national security. This is the main reason why people think about to protect their work and prevent such illicit activities. Because of this various methods like cryptography, steganography, coding etc. have been used. Steganography is the best-suited technique that allows user to hide a message in another message (cover media). Most of steganography research uses cover media as pictures, video clips and sounds. However, text steganography is not normally preferred due to the difficulty in finding redundant bits in text document. To embed information inside a document, its characteristics have to be altered. These characteristics can be either insertion of spaces or non-displayed characters, deliberate misspellings distributed throughout the text, resizing of fonts etc. But due to slight change in the document it will be visible to the third party or attacker. To overcome this problem there is a need to alter the document in such a way that it will not visible to the human eyes yet it is possible to decode it with computer. The Proposed Idea is to have detailed knowledge about the latest methods used in text-based steganography and developed the database in order to use by the security authorities.
