A Greedy Approach to Text Steganography Using Properties of Sentences

Steganography is the art and science of covered or hidden writing. The purpose of steganography is covert communication to hide the existence of a message from an intermediary. Digital Steganography algorithms have been developed by using texts, images and audio etc as the cover media. This paper presents a new approach on text steganography through Indian Languages. Considering the properties of a sentence such as number of words, number of characters, number of vowels etc and using the presence of redundant feature code able characters in Indian Languages, this approach hides the message into an innocent cover file containing Indian texts. This approach also presents the extraction of message from the generated cover file by applying the reverse method of hiding. The approach shows satisfactory results on applying to some topic of daily newspaper in Indian Languages like Bengali.
