Visual Content Privacy Protection: A Survey
Ruoyu Zhao, Yushu Zhang, Tao Wang +3
Vision is the most important sense for people, and it is also one of the main ways of cognition. As a result, people tend to utilize visual content to capture and share their life…
FairCMS: Cloud Media Sharing with Fair Copyright Protection
Xiangli Xiao, Yushu Zhang, Leo Yu Zhang +3
The onerous media sharing task prompts resource-constrained media owners to seek help from a cloud platform, i.e., storing media contents in the cloud and letting the cloud do the…
A multi-level approach with visual information for encrypted H.265/HEVC videos
Wenying Wen, Rongxin Tu, Yushu Zhang +2
High-efficiency video coding (HEVC) encryption has been proposed to encrypt syntax elements for the purpose of video encryption. To achieve high video security, to the best of our…
Indoor image representation by high-level semantic features
Chiranjibi Sitaula, Yong Xiang, Yushu Zhang +2
Indoor image features extraction is a fundamental problem in multiple fields such as image processing, pattern recognition, robotics and so on. Nevertheless, most of the existing f…
On the security of a class of diffusion mechanisms for image encryption
Leo Yu Zhang, Yuansheng Liu, Kwok-Wo Wong +4
The need for fast and strong image cryptosystems motivates researchers to develop new techniques to apply traditional cryptographic primitives in order to exploit the intrinsic fea…
Chosen-plaintext attack of an image encryption scheme based on modified permutation-diffusion structure
Yuansheng Liu, Leo Yu Zhang, Jia Wang +2
Since the first appearance in Fridrich's design, the usage of permutation-diffusion structure for designing digital image cryptosystem has been receiving increasing research attent…
Joint Quantization and Diffusion for Compressed Sensing Measurements of Natural Images
Leo Yu Zhang, Kwok-Wo Wong, Yushu Zhang +1
Recent research advances have revealed the computational secrecy of the compressed sensing (CS) paradigm. Perfect secrecy can also be achieved by normalizing the CS measurement vec…
Bi-level Protected Compressive Sampling
Leo Yu Zhang, Kwok-Wo Wong, Yushu Zhang +1
Some pioneering works have investigated embedding cryptographic properties in compressive sampling (CS) in a way similar to one-time pad symmetric cipher. This paper tackles the pr…
Robust Coding of Encrypted Images via Structural Matrix
Yushu Zhang, Kwok-Wo Wong, Leo Yu Zhang +1
The robust coding of natural images and the effective compression of encrypted images have been studied individually in recent years. However, little work has been done in the robu…
Embedding Cryptographic Features in Compressive Sensing
Yushu Zhang, Kwok-Wo Wong, Di Xiao +2
Compressive sensing (CS) has been widely studied and applied in many fields. Recently, the way to perform secure compressive sensing (SCS) has become a topic of growing interest. T…
