Abstract: Network security and protection of data have been of great concern and a subject of research over the years There are many different forms of steganography mechanisms like LSB, Masking and filtering and Transform techniques. All of them have respective strong and weak points. The Least Significant Bit (LSB) embedding Technique suggests that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden image in the cover file. This technique can be used for hiding images in 24-Bit, 8-Bit, Gray scale format. This paper explains the LSB embedding technique and Presents the evaluation for various file Formats. In a network, the success of the algorithm depends on hiding technique used to store information into the image. This paper is based on the study of steganography with its LSB algorithm. Human biometrics like iris, fingerprint, and face are the unique things for human. That’s why we propose a unique authentication and encryption technique using IRIS biometric pattern of a person. Text message encrypted by cryptographic key which is generated by iris image. Then using LSB algorithm this encrypted text message hide into the iris image. LSB algorithm is implemented in ARM7 LPC2148.
Keywords: Iris image, Steganography, LSB.
