Audio Steganography using Differential Evolution Algorithm

Audio steganography is the art of hiding information inside audio signals and transferring hidden data in an invisible manner. A systematic algorithm to improve defects of substitution techniques in audio steganography is presented. In first step, an encryption algorithm is used to encrypt secret data, then least significant beats coding based Differential Evolution algorithm is used to embed data in audio signal and improve substations process in audio steganography to increase robustness against attacks.
