Detecting - embedding data in image files

Steganography is a kind of information hiding technique that hide a data (text, sound, image?) in an appropriate carrier for example an image or an audio file. The carrier can then be sent to a receiver without anyone else knowing that it contains a hidden message. The objective is to hide the existence of the message and make it diffucult to read with some cryptographic methods. This study gives a new approach to BMP Steganography algorithm which is based on Least Significant Bit (LSB) insertion technique. Due to security option requirements some extra steps are added to LSB technique. This study accepts BMP images as a cover file and any message can be embedded into the cover file without significant changesperceived by a naked eye. Both encoding and decoding can be done using the visual interface of the tool.
