So, steganography easily has upper hand over cryptography and watermarking. Steganography can use almost all kinds of media present over internet to transmit secret data. In this paper, we review some audio steganography techniques, their algorithms and some challenges faced in their design and implementation. We will look in detail some modified techniques for audio steganography. Also, we look at the problems faced with using mp3 files as cover media.
