Security analysis of a self-embedding fragile image watermark scheme
Xinhui Gong, Feng Yu, Xiaohong Zhao +1
Recently, a self-embedding fragile watermark scheme based on reference-bits interleaving and adaptive selection of embedding mode was proposed. Reference bits are derived from the…
Detecting Directed Interactions of Networks by Random Variable Resetting
Rundong Shi, Changbao Deng, Shihong Wang
We propose a novel method of detecting directed interactions of a general dynamic network from measured data. By repeating random state variable resetting of a target node and appr…
A secure blind watermarking scheme based on DCT domain of the scrambled image
Lei Chen, Shihong Wang
This paper investigates a secure blind watermarking scheme. The main idea of the scheme not only protects the watermark information but also the embedding positions. To achieve a h…
Reconstructing nonlinear networks subject to fast-varying noises by using linearization with expanded variables
Rundong Shi, Gang Hu, Shihong Wang
Reconstructing noise-driven nonlinear networks from time series of output variables is a challenging problem, which turns to be very difficult when nonlinearity of dynamics, strong…
Depict noise-driven nonlinear dynamic networks from output data by using high-order correlations
Yang Chen, Zhaoyang Zhang, Tianyu Chen +2
Many practical systems can be described by dynamic networks, for which modern technique can measure their output signals, and accumulate extremely rich data. Nevertheless, the netw…
A self-synchronizing stream cipher based on chaotic coupled maps
Shihong Wang, Gang Hu
A revised self-synchronizing stream cipher based on chaotic coupled maps is proposed. This system adds input and output functions aim to strengthen its security. The system perform…
