STEGANOGRAPHY

ABSTRACT

Steganography (a rough Greek translation of the term Steganography is secret writing) has been used in various forms for 2500 years. Steganography is the art and science of hiding information by embedding messages within other, seemingly harmless messages. It has found use in variously in military, diplomatic, personal and intellectual property applications. Briefly stated, steganography is the term applied to any number of processes that will hide a message within an object, where the hidden message will not be apparent to an observer. This paper will explore steganography from its earliest instances through potential future application.

This paper introduces steganography by explaining what it is, providing a brief history with illustrations of some methods for implementing steganography. Though the forms are many, the focus of the software evaluation in this paper is on the use of images in steganography. We have even discussed various secret communication methods used, its comparison with Cryptography and Digital Watermarking. Finally, future projections on this perfect file encryption technique are made, along with few explanations using our own software and programs.
