Steganography on Multi-media Elements

Abstract

Stegnography is method to make the communication of secret data hiding through a media. A perfect Steganographic in media enables to embedding data in an media, robust and secure way and then extracting it by authorized people. In this paper we introduces a new approach for Least Significant Bit (LSB) based on image and audio steganography that increases the existing LSB substitution techniques to improve the security level of hidden information by introducing secret key technique. The new security method hides secret information within the LSB using secret key combined with LSB to protect data from unauthorized users. In original LSB methods, secret data is present to a specific position of selected media. Because of this, knowing the extracting methods, anyone can extract the hidden information. In our method, we use secret key which is embedded with LSB and the according to selected media the data will be hidden therefore, it is difficult to extract the hidden information knowing the retrieval methods.
