Audio steganography based on least significant bits algorithm with 4D grid multi-wing hyper-chaotic system

Although variety in hiding methods used to protect data and information transmitted via channels but still need more robustness difficulty improve protection level of the secret messages from hacking or attacking. Moreover, several medias one media reduce transmission time band channel is important task define as a gain channel. This calls find other ways be complexity detecting message. Therefore, this paper proposes cryptography/steganography method hide an audio/voice message (secret message) two different cover medias: audio video. use least significant bits (LSB) algorithm combined with 4D grid multi-wing hyper-chaotic (GMWH) system. Shuffling using key generated by GMWH system then LSB will provide extracting original hackers attackers. According analyses obtained results receiver peak signal-to-noise ratio (PSNR)/mean square error (MSE) sensitivity encryption key, proposed has security robustness. Finally, work extra mixture base crypto-steganographic methods.
