  This paper presents a novel 2-3-3 LSB insertion method. The image
steganography takes the advantage of human eye limitation. It uses color image
as cover media for embedding secret message.The important quality of a
steganographic system is to be less distortive while increasing the size of the
secret message. In this paper a method is proposed to embed a color secret
image into a color cover image. A 2-3-3 LSB insertion method has been used for
image steganography. Experimental results show an improvement in the Mean
squared error (MSE) and Peak Signal to Noise Ratio (PSNR) values of the
proposed technique over the base technique of hash based 3-3-2 LSB insertion.
