ABSTRACT and brief CV:
Steganography and Steganalysis: An Overview of Research and Challenges
Seminjar presented by
Sos Agaian

Steganography is the hiding of a message within another message so that 
the presence of the hidden message is indiscernible. Practically, it is 
the art of secret communication. Digital data can be hidden in pictures, 
videos, music, text, binary files, or source code. The key concept 
behind steganography is that the message to be transmitted is not 
visible to the informal eye. In fact, people who are not intended to be 
the recipients of the message should not even suspect that a hidden 
message exists. After September 11 steganography has received enormous 
attention in industry and in academia. Recently USA Today reported that 
Bin Laden was using steganography to disguise his communications.  The 
Internet has become a new form of cold war era “dead drop”. The general 
purpose of steganalysis is to discover the presence of hidden messages 
in digital media. Steganography and steganalysis have not been 
completely examined in detail by the scientific community outside the 
military. It is a relatively new and fast growing field. Over 90% of all 
the open publications have appeared in the past seven years. This area 
now has become a multimillion-dollar research market, and closely 
related to the security of our nation.
In the present talk we summarize our own steganographical research 
accomplishments during the past two years, and propose a number of 
directions for future research. This research has been supported by the 
Center for Infrastructure Assurance and Security and by the Air Force 
Information Warfare Center .
