Abstract: Steganography is the method to hide a message inside another message in such a way that can only be detected by its intended recipient. Text documents have been widely used for a very long time. A number of text steganography algorithms have been introduced. This paper presents a new approach for steganography in Bengali texts. Considering the structure of Bengali alphabet/words, in this approach, we hide the secret message in the text by shifting the specific ‘matra’ towards left, by shifting the points of some characters and by shifting the character ‘ref’ respectively. This approach can be categorized under feature coding methods. The approach shows good result on the sample collected from different Bengali newspaper.
