Steganography applications conceal information in other, seemingly innocent media. Steganographic results may masquerade as other file for data types, be concealed within various media, or even hidden in network traffic or disk space. We are only limited by our imagination in the many ways information and data can be exploited to conceal additional information.
For many years Information Hiding has captured the imagination of
researchers. Digital watermarking and steganography techniques are used
to address digital rights management, protect information, and
conceal secrets. Information hiding techniques provide an
interesting challenge for digital forensic investigations.
Information can easily traverse through firewalls undetected.
Research into steganalysis techniques aids in the discovery of
such hidden information as well as leads research toward improved
methods for hiding information.
Related research themes include: anonymous communications,
anonymous online transactions, covert channels in computer systems,
covert/subliminal communications, detection of hidden information
(steganalysis), digital forensics, information hiding aspects of
privacy, steganography, subliminal channels in cryptographic protocols,
watermarking for protection of intellectual property,
and other applications.

Dr. Neil F. Johnson began investigating steganography tools and techniques
in 1995. His passion and interest in the topic lead to a Ph.D. and
continued post-doc research. See some of his publications on:
- Countermeasures to cttacks against steganography and watermarking (includes identifying fingerprints of images for recogntion and tracking)
Visit Dr. Johnson's research and publications
for a more complete listing of his work including references for:
- Conference Papers
- Journal Papers, Technical Reports, and Articles
- Books: Chapters and Articles
- Invited Talks, Lectures, and Presentations
- Press Releases and Interviews
One of the many resources Neil had developed over the years includes a
Digital Image Steganography and Digital Watermarking Tool Table. An updated version of this table
is Steganography Tools - authors may submit software to be included.
