- W2331286942 abstract "DOI: 10.1049/ic.2009.0139 ISBN: 978-1-84919-193-7 Location: Maharashtra, India Conference date: 19-20 Sept. 2009 Format: PDF Given the shear volume of data stored and transmitted electronically in the world today, it is no surprise that countless methods of protecting such data have evolved. Our paper is part of information technology field called the information hiding. It is mainly divided into two parts: steganography and watermarking. Steganography is the art and science of hiding information so that it does not even appear to exist. Steganography is used not to encipher the information, but to hide the occurrence of communication in some sort of communication medium called stego-object. The secret information is called an embedded data. As an example we may consider images on the Internet, spam messages etc. Watermarking as the name suggests is a technique which allows an individual to add hidden copyright or other verification messages to digital audio, video, or image signals and documents. Such a message is a group of bits describing information pertaining to the signal or to the author of the signal (name, place, etc.). The technique takes its name from watermarking of paper or money as a security measure. Digital watermarking can be a form of steganography, in which data is hidden in the message without the end user's knowledge.
