Abstract: Steganography is the art of hiding facts where communication is taking place, by hiding information in another information. The purpose of Steganography is to maintain secret communication between two parties. Many different file format carrier can be used, but the digital image are the most popular bacause of their frequency on the internet. In this paper a new algorithm is described for hiding a secret image in the least significant bits of a cover image. Least Significant-Bit (LSB) based approach is most popular steganographic techniques in spatial domain due to its simplicity and hiding capacity. This method supports both type of images colour and gray scale image. How many LSB hides the secret information is decided by the exclusive-or (XOR) operation of a pixel’s neighbour. Here result is sensitive to the smothness of the neighbour pixel.
