A new method for audio steganography using message integrity

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 X2 are two criteria used in the experiment to gauge the robustness and imperceptibility of the stego–object file for the proposed SSAS.
