Data hiding is the art of hiding data for various purposes such as to maintain private data, secure confidential data and so on. The network provides a method of communication to distribute information to the masses. With the growth of data communication over computer network, the security of information has become a major issue. There are lots of techniques used for data hiding and the well known technique is the Steganography. Steganography is art and science of invisible communication. Steganography is the method through which existence of the message can be kept secret. This is accomplished in the course of hiding information in another information, therefore hiding the existence of the communicated information. This paper presents a brief idea about the image steganography that make use of Least Significant Bit (LSB) algorithm for hiding the data into an image.
