Abstract

Abstract: With rapid development of multicast communication, multimedia share services have become one of the most important channels for steganography. In this paper, we extend traditional unicast steganography to multicast steganography, which is the covert communication of a single sender attempting to deliver different secret messages simultaneously to several receivers within the same cover object. The general model of multicast steganography is first presented, and the newly spawned problems are discussed including the intergroup privacy, extended embedding efficiency and information retrieval immediacy. Then with the widely used matrix embedding strategy, synchronous and asynchronous multicast matrix embedding frameworks are proposed respectively; the former is based on Slepian–Wolf coding, and the latter employs overlapped multi‐embedding. The state‐of‐the‐art syndrome‐trellis codes are taken as examples to illustrate the performance of the proposed two schemes in experiments, which shows that the former scheme can achieve higher embedding performance, while the latter one can guarantee better intergroup privacy and information retrieval immediacy.
