Abstract
Steganography is the art of hiding the fact that communication is taking place, by hiding
information in other information. Steganography is a method of hiding secret data by embedding
it into an audio, video, image and text file. It is one of the methods employed to protect secret or
sensitive data from malicious attack. Many different carrier file formats can be used, but digital
images are the most popular because of their frequency on the internet. For hiding secret
information in images, there exist a large variety of steganography techniques some are more
complex than others and all of them have respective strong and weak points. Different
applications may require absolute invisibility of the secret information, while others require a
large secret message to be hidden. This project report intends to give an overview of image
steganography, its uses and techniques. It also attempts to identify the requirements of a good
steganography algorithm and briefly reflects on which steganography techniques are more
suitable for which applications.
