The object of steganography is to send a message through some innocuous carrier to a receiver while preventing anyone else from knowing that a message is being sent. The carrier can be one of several forms of digital media however the most common type of carrier used is an image. The image should not attract any attention as a carrier of a message and should look as close as possible to an ordinary image. This paper summarises recent research in the area of steganography with the aim of evaluating the trends in this area and developing a perspective on it. It looks at the application of steganography to digital images. Different ways of hiding the message sender arc discussed. An extensive study of existing steganography software is provided. Watermarking and cryptography are briefly described. Watermarking is the process of hiding information in a carrier in order to protect the ownership of text, music, films and art. Steganography techniques can be used for the purposes of watermarking. It is important also to briefly mention cryptography as it is commonly used along with steganography to generate an encrypted message to be hidden in a carrier.
