This paper proposes an effective data hiding scheme for a binary host image for the purpose of access control, authentication and copyright protection of digital media. The binary image is divided into blocks of size 2 x 2. These blocks are classified as embeddable or non-embeddable blocks according to their characteristic values, and a binary data sequence(More)
Network coding is an effective means to enhance the communication efficiency. The characterization of network solvability is one of the most important topic in this field. However, for general network, the solvability conditions are still a challenge. In this paper, we consider the solvability of general quantum k-pair network in measurement-based(More)
