The Internet of Things (IoT) is a network of objects; it is enabled by the Internet technologies. The IoT always collects sensitive data, but inadequate protection may lead to serious user privacy leakage. Thus, privacy protection functions are important to the IoT. Our research aims to provide better privacy protections to IoTs. Firstly, user controlled privacy preserved access control protocol is...
Nowadays, social networks, information networks and technological networks have already become main media of information publication and exchange. Meanwhile, the information diffusion in these networks is well studied. However, most privacy protection technologies, e.g., access control, have not considered the influence of these networks systematically. In this paper, a concept of outer system flow...
In the following years, the desktop-based applications will be changed to cloud computing gradually. Since all users' profile and context data will be stored on the service supplier side based on their ID. ID is becoming a security bottleneck: attackers can trace all other information via user ID. Increasingly, a simple service may be involved in a chain of service clouds; each cloud is able to access...
