Nowadays, the internet is a very powerful and valuable medium of communication, dissemination of information, and connectivity to away people. Moreover, it is very important to keep ourselves secure online. In this regard, steganography is a system providing an enhanced secured communication process. The word steganography originates from the Greek word steganos (which means hidden or covered). It conceals the pursuit of communication. On the other hand, cryptography provides an encryption mechanism to make the secret message decodable. Steganography offers confidentiality, authentication as well as data integrity but non-repudiation. Numerous research has already been done on audio steganography. Among all, this proposed method gives enough good outcomes. This paper proposes a technique to conceal information in an audio signal using the audio-steganography method and presents an enhanced two-level secured communication to hide confidential information by encoding data using the GA (Genetic Algorithm). The SNR (Signal to Noise Ratio) value can calculate to evaluate the quality of both the cover and stego audio signal. The stego audio signal provides a higher SNR value which is positive and near to one. The proposed steganography method provides a higher secured communication and hiding capacity. This method also works efficiently to hide information in the audio signal and is more transparent acoustically.
