Dwt and Lsb based Audio Steganography
Neha Gupta, Nidhi Sharma · 2014
Steganography is a fascinating and effective method of hiding data that has been used throughout history. Methods that can be employed to uncover such devious tactics, but the first step are awareness that such methods even exist. There are many good reasons as well to use this type of data hiding, including watermarking or a more secure central storage method for such things as passwords, or key processes. Regardless, the technology is easy to use and difficult to detect. Researchers and scientists have made a lot of research work to solve this problem and to find an effective method for image hiding .The proposed system aims to provide improved robustness, security by using the concept of DWT (Discrete Wavelet Transform) and LSB (Least Significant Bit) proposed a new method of Audio Steganography. The emphasize will be on the proposed scheme of image hiding in audio and its comparison with simple Least Significant Bit insertion method for data hiding in audio.
