Hindi text steganography - An approach to information hiding

摘要

Steganography, the method to hide a message inside another message without drawing any suspicion to the others and that the message can only be detected by its intended recipient. Text documents have been widely used for a very long time. With the other steganography methods such as Image, Audio, Video, a number of text steganography algorithms have been introduced. This paper presents some new approaches for steganography in Hindi texts. Considering the structure of Hindi alphabet/words, in this approach, we hide the secret message in the text by shifting the subpart of some Hindi characters towards left or right, by rotating the line within the main character of some Hindi characters, by shifting the rightmost vertical line of the parallel lines formed by combining the consonant with vowel, by adding more spaces between the subparts of medial vowel and by shifting the point of the medial vowel. This approach can be categorized under feature coding methods. The approach shows good result on the sample collected from different Hindi newspaper.
