Steganography, Steganalysis & Watermarking
COURSE GOALS
The use of images and audio data for
covert channels, copyright protection, and ownership of data has seen
an explosion of interest during the past 5-10 years. This class
focuses on the broad topic of digital information hiding for
steganographic and watermarking techniques. Steganography concentrates
on hiding a message in an innocuous carrier to conceal the existence of
the message. Digital watermarking is concerned with issues related to
copyright protection and intellectual property, and data watermarked
for these purposes typically contain information about the data itself,
such as the owner or contact information. Cryptography, on the other
hand, is the study of scrambling a message so that if and when it is
intercepted, it cannot be understood. Analyzing data in which
information has been hidden is called steganalysis, and analysis
techniques can be used to detect, extract, change or ultimately destroy
the hidden information. Results of steganalysis can also be used to
change or improve embedding techniques. This course gives an
introduction to steganography and watermarking and some analysis
techniques for various applications, including military, copyright
protection, and intellectual property.
