Abstract: A significant amount of research is done to improve the effectiveness in data hiding. Audio steganography is an art of hiding secret information inside an audio file, such that the representation of audio file won’t be altered. Steganography is one of the safest ways of secret data transmissions in today’s digital world. In this paper, large embedding capacity steganography method is proposed using LSB substitution. Alongside, the power and security of the RSA cryptosystem is based on the fact that the factoring problem is “hard.” The public and private keys are related mathematically, but the parameters are chosen so that calculating the private key from the public key is either impossible or prohibitively expensive. Thus two level security and robustness is achieved. The original and stega-audio signals show resemblance hence there is minimum chance of detecting the secret message hidden in the stega-audio. MATLAB is used for proposed algorithm and proposed results have been shown.
