A New Image Steganography Method using Message Bits Shuffling

Prithwish Das
Steganography has been considered as a technique of message hiding within another carrier multimedia data. Messages in the form of image (with embedded handwritten or typed texts) are often embedded in several ways within another image in image steganography. DCT based schemes are undertaken in the frequency domain methods in addition to usual plain text message embedding. Most of the message image hiding techniques embeds image bit string without considering any shuffling schemes to deal with

Present work targeted to incorporate message hiding essentially with shuffled and re-shuffled bit strings in different ways prior to DCT operation. A new method has been proposed with these shuffling schemes to enhance the security level of the encryption. Investigations with the proposed image steganography method show that the new methods performed better than normal image steganography techniques without shuffling schemes. Performance of the proposed method is evaluated using Peak-Signal-to-Noise Ratio (PSNR) and Mean Square Error (MSE). Results show that the shuffling bit steganography method outperformed the common DCT based schemes without shuffling.
