Matrix embedding (ME) is a well-known steganographic method that can improve the embedding efficiency. In ME, the sender and recipient agree in advance on a parity check matrix (PCM) of a binary linear code and utilize the PCM for data embedding. At the decoder side, the embedded message can be extracted by the recipient as the syndrome of the received stego data. The PCM can be taken as any full-ranked...
Matrix embedding is proved an effective way to improve embedding efficiency of steganography, and usually, higher dimensional matrix will provide better embedding efficiency. However, the sender might suffer huge computational complexity when employing high dimensional matrix. In this paper, a variation of matrix embedding is proposed. Instead of finding a coset leader as the modification of the cover...
Embedding efficiency is a metric of steganographic security. Higher embedding efficiency is usually desired to get more secure steganography. Matrix embedding is proved an effective way to increase embedding efficiency of steganography, and meanwhile the choice of matrix plays a key role in matrix embedding. Different matrix (with the same dimension) usually results in different embedding efficiency...
In order to enhance the steganographic security, higher embedding efficiency (average number of secret data bits embedded per one embedding change) is desired. Matrix embedding is a well-known steganographic scheme that can improve the embedding efficiency. However, the embedding cost (running time) is expensive when employing high dimensional matrix, while higher dimensional matrix usually provides...
Embedding efficiency, which is defined as the average number of secret data bits embedded per one embedding change, is an important attribute directly influencing the security of steganography. Higher embedding efficiency is usually expected to get more secure steganographic method. In this paper, by incorporating two previously introduced techniques: the ldquosum and difference covering setrdquo...
As an important attribute directly influencing the steganographic scheme, the embedding efficiency is defined as the average number of random data bits per one embedding change. In this paper, we propose a novel approach to improve the embedding efficiency of LSB matching based on the sum and difference covering set (SDCS) of finite cyclic group. We show that the suitable choice of SDCS will lead...
