Privacy is considered to be a critical issue for providing high quality ubiquitous network services to users over the Internet. User's privacy should be protected and access to privacy information must be controlled in accordance with user's privacy preferences. Existing privacy-aware access control strategies often store all the privacy access control policies on the server side and thus fail to...
Privacy protection is one of the important topics in network security. Although a lot of work has been done, there are still some open issues and challenges that need to be addressed. Now, open and dynamic computing environments offer flexible and convenient sharing of information and services for users. Consequently, there exist a lot of different policies for privacy protection to deal with dynamic...
In open and dynamic computing environments, the entities that make connections and interactions may know little about each other or without prior knowledge. So, certain level of trust must be established. This may require that an entity request some information from other entities that probably involves privacy. Therefore, quantifying privacy loss and trust gain is a meaningful and important subject...
The emergence kinds of Web applications offer flexible and convenient service for users.

That is clearly that some sites disclosed user's privacy such as preference with user's email address to the third party by their commerce interests...
The Internet and computers did not invent or even cause privacy issues. The issues existed long before the creation of computers and Internet. The existence of the Internet, computers and large data storage make it possible to collect, process and transmit large volumes of data, including personal data. In this paper, we shall study the privacy from following two different views, namely legal framework...
Privacy protection is a very important issue and solutions must be developed for wide acceptance of location based services (LBSs) in wireless applications. Current approaches rely mostly on the use of privacy policies to describe and solve this problem in an ad hoc way. In this paper, we propose a method based on the three-dimensional access control model to support privacy requirements. We show...
Privacy is one of the most important issues in providing high-quality ubiquitous network services to users over the Internet. Although several privacy aware access control models have been proposed in recent years, these models still rely mostly on the traditional access control models designed primarily for security. When privacy becomes a main concern, these models are no longer adequate. In this...
