Abstract :
- Encryption, the process of data hiding at the
time of transmission, gives security to messages. Audio
signal is vastly used for communication now a days.
This paper is about an algorithm of audio file
encryption in image format by usingprivate keyand
decryption into audio. Audio encryption which is bulky
in size can be overcome by processing audio signal to
image. It ensures secured transmission of data by
changing its features. Here, in this algorithm,
dimensions of raw datahave been changed and the
reshaped format has made signal privy. This technique
provides lossless data processing as well as renders the
choice of selection of any types of audio file (mp3, wave,
m4a etc.) in mono or stereo. Here security
enhancementis done by using private key and changing
properties of data from audio to image. Use of
compression adds white noise which can be removed by
using proper filter. It gives improved SNR, more than
18dBafter reception. For better communication system,
this process is easier and better than other encryption
techniques
Keywords :
Encryption, Decryption, Random private key, Mono, Stereo, Filter, SNR.
