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...
