A Proposed Method for Audio Steganography Using Digital Information Security

In the current era of digital technology, the information security is the challenging task. For the secrete communication information hiding is an essential element. The current information steganography system uses objects like audio, image and video. The audio steganography is the technique that convey hidden message by modifying an audio signal in an unnoticeable manner. It is a technique for the hiding secret message in the host audio signal. The original audio message before steganography and after encoding message is having uniform characteristics. The embedding secrete audio message in the original audio file is a more challenging and difficult task. This paper presents the comprehensive survey of audio steganography techniques for information security. The experiment was tested using proposed LSB technique for audio steganography. This paper extended towards quality measure of steganography message. The quality of audio steganography measures using energy score, Mean square error, Peak signal to noise ratio. From this experiment the quality of audio steganography is observed as 92.759% for MSE and 94.971% for PSNR technique. Audio information hiding is the one of the robust and dynamic ways of protecting the privacy and secretes communication.
