In a digital multimedia era, the security of multimedia over network transmission
becomes a challenging issue. A strategy, combining cryptography with
steganography, is investigated to overcome the problems in hand. This paper
proposes hiding secret messag
es; represent (text, image, digital audio or any data)
in a digital audio file after encrypting the original data using RSA method.

The research of using steganography is to invent an intelligent use of

Camouflage such that no one except the authorized per
son can read the secret
message after
decryption
.

Cryptography
, on the other hand, is concerned with strategies based on a
secret
key for enciphering or concealing data such as text, image, audio, and video data.


This paper assumes that the secret message

is represented as a binary format. This
Secret message will be encrypted using RSA method, and then will be inserted
into the audio file (both .MP3 and .WAV can be used) using the Least Significant
Bit (LSB) method. On the other hand, to reveal the messag
e, first a bit gathering
operation is needed to form the encrypted message, then a decryption operation is
done using RSA Decrypt method.
