This document discusses steganography and its potential use for cyber terrorism. It defines steganography as "covered writing" and describes how terrorists may hide messages in media like images and audio files using techniques like least significant bit encoding. The document outlines security issues with steganography, how it has been used in past terrorist attacks, and challenges in detecting hidden messages. It proposes strengthening steganalysis through increased awareness, training, proactive investigations, and prosecuting those misusing hidden communication technologies for criminal purposes.

3. ABSTRACT:
Terrorist
attacks
WORLD
Technology
Security systems for
their msg transfers
Misuse of greatest security systems --- protection from them

4. INTRODUCTION:
Steganography: “covered writing” in Greek
LSB or Noise

5. STEGANOGRAPHIC TECHNIQUES:
Presently Implimenting stegnography in audio files is in research

6. STEGO HIDING:
Actual code:
Stegn’d code:

7. STEGANOGRAPHIC SECURITY:
An experiment that measures the capability of the adversary
to detect the presence of an embedded message
The equation shows the degree of detection and which in
turn increases the reliability of the Steganalysis detector
Bad steganography can even be worse than no steganography
at all, since it gives the user a false sense of security

8. STEGANOGRAPHY IN TERRORISM:
Al Qaeda terrorists --- pornography ---- Stego media.
rumors in usage of steganography in WTC Tower crash,
also some evidences are proved that laden used Stego
statements to his followers as “kill Americans”
The image of seating
information of Boeing
757,(the hijacked
flight used by
hijackers) is the
secret msg in the
picture of Mona Lisa

9. DETECTING STEGANOGRAPHY:
as in INTERNET billions of pictures trnsfer in a
day a narrow down process(3 steps) is nesessary
as shown in pic below

10. DETECTING STEGANOGRAPHY:
Secret msgs
Hue view to detect stegnography

11. Increase awareness and provide training for law
enforcement investigators and forensic specialists in
the detection and analysis of convert information.
Perform pro-active cyber investigations that uncover
the use of steganography and other advanced data
hiding or covert techniques.
Intensify efforts and step up the prosecution of those
using these technologies for either criminal or
terrorist purposes.
Measures to strenthen Steganalysis:

12. CONCLUSION:
Using steganography for unlawful events might be
the disadvantage and also the technically,
detecting Stego in many number of images may
take long time. But, steganography might be the
better supplement for any of the secret writings,
which provides better security.
Hence bigger grants from governments
on reaserch must be issued inorder to make
the best use of stegnography.
