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

Abstract

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

Ameliorating LSB Using Piecewise Linear Chaotic Map and One-Time Pad for Superlative Capacity, Imperceptibility and Secure Audio Steganography

“…Concerning security, table 8 depicted that the proposed LSB PW LCM method can withstand brute force attacks as its key space has considerable size of ≥ 10 64 ×MsgSize. Ergo, as can be seen from the comparisons with researches [13], [4] and [50], it is dominating prevailing schemes. Moreover, its key space depends on the size of the message, MsgSize.…”

“…Their method has some limitations including the prolonged encoding time besides robustness. On the other hand, researchers [50] came up with a different idea to shuffle an audio using 4D grid multi-wing hyper-chaotic key generated before embedding using LSB to provide more security. Albeit their method has a large key space providing more security, it has a lengthy transmission time in addition to low hiding capacity and low resolution.…”

Multistage Encryption for Text Using Steganography and Cryptography

“…Where n is equal to 8 and its meaning is the number of bits per pixel of the image and MSE is the Mean Squared Error (MSE) between the stego image and the cover image that is defined in (2) [14].…”

“…A fundamental LSB substitution procedure involves converting m samples of a secret message from integer numbers to binary. In the end, the secret message bits will replace every single bit pixel of the cover image [14]. Instead of dots, spaces, dashes, and slashes, a binary format is used in this work such as in Table 2 which the ciphertext change to binary format using to decrease the number of pixels that use in the process of a substitute.…”

Identifying optimal message embedding location in audio steganography using generative adversarial networks

“…Audio Steganography is a method of transmitting concealed information by altering an audio stream in an undetectable way [17]. This method can conceal a hidden text or audio message inside a host [18]. Host message characteristics, before and during steganography, are identical to those of the stego message itself.…”
