This is the final presentation for project named "Audio Steganography" for btech final year computer science students, and without the screenshots of the progress this can b used as a synopsis presentation.

It refers to the transfer of data such as
TLS and SSL are cryptographic protocols that
provide secure communication on the internet.
The process of hiding the messages so that the presence of
message itself is hidden , often by writing them in places
where they may not be found.

Embedding secret message into
digital sound is called audio
Audio Steganography is presented
where the bits of a secret message
are embedded into the coefficients of
a cover audio.
Take an audio input from the user.
Convert audio bits into binary format.
Embed the secret message with binary bits
Decode the message with the same
procedure as applied in embedding.
Now original message can be viewed by

Hiding information may introduce enough
visible noise to raise suspicion. Therefore the
carrier or cover audio must be carefully
This proposed system is to provide a good,
efficient method for hiding the data from
hackers and sent to the destination in a safe
This proposed system will not change the
size of the file even after encoding and also
suitable for any type of audio file format.
Encryption and Decryption techniques have
been used to make the security system
