Now-a-days, Internet becomes a big source for sharing information. When people share the data or information over the internet, they keep two important factors in their minds reliability and security. To achieve these factors, people are always trying to adopt new ideas. Image steganography is one of the famous method that is used to hide the secret data in the carrier image in the way that the carrier image having the secret data/information should not be detectable by human visual system (HVS). So we are going to design an approach for image steganography in which we will use the hash based technique with three Least Significant Bits method in the order of RGB 3-2-3 respectively. Our proposed approach will show the strong capability to read the information from text file and hide it in the image of any format like bmp, gif, jpg, jpeg and tiff without destroying the picture quality of stego image. No distortion in the image quality is detectable by Human Visual System. Experiments show that our proposed approach is providing better imperceptibility rate. So it enhances its security. Our proposed approach works efficiently as it is hash based. Every time it generates random hash key value. So it is not possible for any attacker or unauthorized person to get the hash key value. Hash Techniques improves its performance. Least Significant Bit Method makes it simple. Our proposed technique has also the high embedding capacity rate.
