A new LSB-S image steganography method blend with Cryptography for secret communication

In this paper, a new method of image steganography in spatial domain on gray images blend with cryptography is present. Steganography and cryptography are used to hide message and its meaning respectively. By this method, the message is first encrypted using Vernam cipher algorithm and then the message (encrypted) is embedded inside an image using the new image steganography method i.e. LSB with Shifting (LSB-S). In LSB-S method we have used four LSB of the pixel and performed circular Left shift operation and XOR operation. The combinations of Cryptography and steganography method enhance the security of embedded data. After implementation the proposed method it is checked on the different parameter such as PSNR and MSE and got good results.
