Abstract With the advancement of information technology, there is a visible change in economical, commercial, and technological ways. Privacy of information still remains the main concern. Audio steganography is one of the most popular techniques for shielding of information. To raise the surveillance, we focus on Audio steganography along with noise-free environment. For ensuring this, hiding in silence interval are considered because most of the current audio steganography embedding methods are improper for noise-free environment. This paper proposing an attainment upgrade in audio steganography with using RSA algorithm of three distinct prime numbers as well as hiding text in silence speech signals with high hiding capacity employing summate silence interval in speech signal. Our simulation results show that this approach maintains noise-free environment, security, and achieves a higher hiding capacity. Keywords Steganography

1 Introduction Internet is a global system of computer networks. So with advancement of these come up with many security problems, exceptionally in data security. Data security means defend data from the undesirable movement of illegal end users. Cryptography and steganography are the two techniques used to solve these problems. Cryptography is the branch and trade of remodeling information to make

them sheltered and resistant to intrusion. Encryption and decryption are two important methods used under cryptography. Steganography is termed as shielded or obscure writing [1]. It is forming of shielded through uncertainty. Audio steganography is technique used to remodeling covert information by reshape audio signals in an undetectable manner [1–3]. General principles of audio steganography adopted in previous research are as follows. In audio steganography system, to support cryptography, normally RSA algorithm is used. RSA is an unbalanced cryptographic algorithm that contains key generation (public and private), key distribution, encryption, and decryption [4, 5]. In this, prime numbers must be undisclosed and anyone will get a public key to encipher the message where any case of cracking RSA encipher known as RSA problem. Variety of methods are used for embedding text into an audio file such as LSB [6], MSB, phase coding, parity coding [6], hiding in silence interval. As our intention is to get a noise-free environment, in our proposed work, we focused on the Hiding in silence interval [2, 7]. Hiding in silence interval is a smooth and an adequate embedding method has been employed to accomplish silence interval i
