-Steganography is the technique of hiding secret message in a cover medium in such a way that only the sender and the intended recipient knows the existence of communication. DNA due to its immense storage capacity and high randomness is used now in the field of steganography. Though many algorithms have been developed for hiding the data, DNA sequences based data encryption seems to be a promising strategy for fulfilling the current information security needs. Audio steganography is concerned with hiding information in a cover (host) audio signal in an imperceptible way. In this paper, various techniques using DNA Sequences and audio files for data hiding is discussed for secure data transmission and reception.
