Steganography
1. Steganography
*steganography is data hidden within data.
*Steganography is an encryption technique
that can be used along with cryptography as
an extra-secure method in which to protect
data.
*Steganography techniques can be applied to
images, a video file or an audio file. Typically
2. • however, steganography is written in characters
including hash marking, but its usage within images is
also common.
• At any rate, steganography protects from pirating
copyrighted materials as well as aiding in unauthorized
viewing.
3. Step of crime
• Information hiding can
also be used by an
attacker during
different attack stages
depending on what
information is being
hidden:
• Identities. The
identities of
communicating parties
are hidden by
anonymization
techniques.
4. • Communication. The fact that a communication is taking
place is hidden by steganography techniques.
• The characteristics of a network conversation (for
example, a packet flow) can be concealed using traffic-
type obfuscation methods.
• Content. Hiding the content of data but not the
transmission or presence of the data itself is achieved by
applying cryptographic algorithms.
• Code. The structure of (executable) code is hidden by
(binary) code obfuscation and masquerading techniques.
