Comparative Analysis of Efficient Image Steganographic Technique with the 2-bit LSB Algorithm for Color Images

Abstract: Steganography is the process of embedding data bits on carrier or cover file. If the carrier file is an image file, then it is called as image steganography. In this proposed method, an image steganographic technique is applied on only red and green planes of 2-bit LSB and also the experimental results are compared with the general two bit LSB (i.e., red, green, blue planes) algorithm. We observed our proposed algorithm is giving best results in terms of quality of the stego image.
