Secure Data Hiding Algorithm Using Encrypted Secret message
P. Vijaya · 2012
In any communication, security is the most important issue in todays world. Lots of data security and data hiding algorithms have been developed in the last decade, which worked as motivation for the research. This project is a combination of steganography and cryptography, which provides a strong backbone for its security. The scenario of present day of information security system includes confidentiality, authenticity, integrity, non-repudiation. This present work focus is enlightening the technique to secure data or message with authenticity and integrity.In this project work, the secret message is encrypted before the actual embedding process starts. The entire work has done in MATLAB. The hidden message is encrypted using a simple encryption algorithm using secret key and hence it will be almost impossible for the intruder to unhide the actual secret message from the embedded cover file without knowing secret key.Only receiver and sender know the secret key.N-bit LSB substitution technique is used as embedding and extraction method . We propose that this method could be most appropriate for hiding any secret message (text,image ,audio,video) in any standard cover media such as image, audio, video files.
