Contributed by Neha Sharma, Mr. J. S. Bhatia, and Dr. Mrs. Neena Gupta

Digital communication has become an essential part of infrastructure nowadays, a lot of applications are Internet-based and in some cases it is desired that communication be made secret. Consequently, the security of information has become a fundamental issue. Two techniques are available to achieve this goal: Encryption and steganography is one of them.
