Abstract


In recent years, innovation of technology and fast internet services make it possible to distribute the information and digital services to the overall world in a simple and cost effective manner. The rapid growth in information technology and digital communication has become very significant to protect the information transmission between sender and receiver. Steganography is the process of embedding original message bits on some carrier file. The carrier file may be text file, image file, audio file or video file etc. If that carrier file is an image file, then that technique is called Image steganography. If color image is used as a carrier file to embed data bits, then that type of steganographic technique is called as color image steganography . Therefore, Steganography introduces a strong way to conceal information and to converse a secret data in an appropriate multimedia carrier file, eg. Image, text, audio and video files. In this paper, an adaptive lossless data hiding technique is presented which is capable of hiding some bits of large size audio wave file binary information into an image using 2 bit LSB method and the remaining bits by generating decimal key vector.

Keywords


Steganography, color image steganography, multimedia carrier file, LSB method decimal key vector.
