What is Steganography :
It is the art of
hiding secret message inside ordinary message (which has no meaning).
Steganography is alternate to encryption. Steganography is the useful technique
to achieve computer security or information security.
In
encryption the message to be kept secret (which is in plaintext/readable
format) is applied to encryption algorithm and as a result of encryption
algorithm the plaintext message get converted into ciphertext (ciphertext is
the text which is not readable and understandable) and transmitted to
destination.
If
there is a person who capture the transmission media and who is able to sniff
the messages in transit then the secret message in ciphertext form may attract
to that third person. Ciphertext are point of attractions since it don’t have
meaning, so the ultimate aim of attacker is to understand the ciphertext.
