Combination of Steganography Using Parity Encoding and Spread Spectrum Technique

Steganography is a well-known method of hiding covert messages to obtain information security. In steganography the unused bits of data in sound, image etc. files are replaced with bits of secret information. In audio steganography an algorithm is used for hiding secret messages in audio files. Here in this paper, information hiding is achieved using two different steganographic methods instead of a single steganographic method. This is called as multi-level steganography. Multi-level steganography allows the hiding of two messages into a single cover object.
