Steganography is a technique for hiding secret data within various file formats such as images, video, and audio. It can provide an extra layer of security beyond encryption alone by concealing the very existence of secret messages. Common steganography methods embed hidden text as small changes to pixel values in images or alterations to audio/video files imperceptible to human senses. The hidden data can be used to protect copyrighted materials or enable unauthorized access.

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.

5. Step of crime

6. 1.INSERT Your picture and enter the
Secret message
2.Save image
Step of Encode

7. Step of decode…..
1.Insert image that u want to
make decode
2.Image will pop up (“kill tarun”)
