Abstract Steganography which is normally used to solve security issues can be implemented using two processes, namely embedding and extracting. With current steganography methods it is not possible to ascertain and verify that the secret message has been attacked or otherwise. This paper proposes an enhanced secure method for audio steganography (SSAS) which can perform better than that proposed by Atoum et al [11]. This proposed method has the capability to verify whether the secret message has been attacked or not, thus improving the message security. PSNR and X 2 are two criteria used in the experiment to gauge the robustness and imperceptibility of the stego–object file for the proposed SSAS. Keywords: Steganography, Message Integrity, LSB, MP3 1. Introduction Nowadays, internet has become a key technology in which information is gathered, processed and distributed to people in different parts of the world. The internet enables quick and efficient information communication and acquisition. One of the issues of great concern to many users of the internet is information security. There are two basic ways in which information can be made secure; these include cryptography and steganography [1]. Cryptography is a Greek word which means secret writing. It refers to the process of changing information into a form that is hard to recognize using well defined rules (keys) which ensure that only those specific people who have the keys can get access to that information [2]. Steganography is a Greek word which means covered writing. It refers to hiding information or object in a secret place that cannot be accessed and detected by anyone except those who are familiar with the secret sender [2]. This paper introduces various concepts of steganography and compares the different communication protocols used. It discusses several important research works to show that not all steganography schemes use message integrity. This paper proposes SSAS and discusses the performance of SSAS through results of tests and experiments conducted.
