With the growing importance of the internet, secure transmission of information is crucial. Steganography and cryptography helps in providing this much needed data confidentiality. Steganography hides secret information into a cover medium and cryptography converts data into an unrecognizable form. In this paper, the authors proposed a novel approach for concealing data. The proposed algorithm is an amalgamation of text encryption, audio steganography and audio encryption. In the first step, the original text message is encrypted using modified Vigenere cipher algorithm. This cipher text gets embedded into the cover audio using LSB encoding, in the second step.
