Abstract

We have developed a quick and dependable algorithm for audio steganography. Proposed technique is succesful to embed a secret message right into a sound file. Cover sound is modified and hidden message is made imperceptible. Our steganography algorithm outcomes extraordinarily strong to:

 

Random white noise

MPEG compression

Random cropping

Resampling

Many different widespread sound processing algorithms

 

Our code might be merely used as an imperceptible audio-QR for broadcast communications so as to add additional-contents into an audio sign. For instance audio sign can be utilized to hold further info and a cell phone can reveal such contents just by launching a shopper-aspect software to disclose the key message. Moreover the introduction of a random key assures that nobody will have the ability to perceive the message with out the information of the required numeric key.

Keyword: Matlab, supply, code, speech, audio, encryption, system, steganography, hidden, message.
