Abstract

Steganography means study of invisible communication that usually deals with the ways of finding the
existence of communicated message. It has many applications in computer science and other related fields. Different
steganography techniques are used to protect the information accessed by unauthorized person. Some methods of
steganography are image, video, text and audio respectively. Image based steganography techniques are most useful
techniques nowadays. In this paper I reviewed how the images can be used as the covering medium for text messages.
