Steganography is the art and science of hiding that a communication is taken place. It embeds the secret file (text, audio or image) in other carrier file. Image steganography has widely developed. There are also many algorithm developed for it. Meanwhile, the interest in using audio data as cover object in steganography can be spelled out late emergence than image data. Audio information hiding has attracted more attentions recently. Spread spectrum (SS) technique has developed rapidly in this area due to the advantages of good robustness and immunity to noise attack. The spread-spectrum techniques for watermarking are very popular nowadays. Cryptography plays a major role in the field of network security. There are many encryption techniques available currently to secure the data. Cryptography can be defined as the art or science of altering information or change it to a chaotic state, so that the real information is hard to extract during transfer over any unsecured channel. Latest advancements in technology and new concepts like quantum cryptography have added a complete new dimension to data security. MATLAB R2013a has been used as an implementation platform using signal processing tool box.
