The security and privacy of patient information is one of the biggest hindrances to the wide adoption of eHealth systems. For eHealth systems to be successful they must provide protection for patients' privacy while ensuring healthcare professionals are able to access the information necessary to provide appropriate care. Accountable-eHealth systems are a proposed solution to these potentially competing...
During natural disasters or emergency situations, an essential requirement for an effective emergency management is the information sharing. In this paper, we present an access control model to enforce controlled information sharing in emergency situations. An in-depth analysis of the model is discussed throughout the paper, and administration policies are introduced to enhance the model flexibility...
Python programming language supports third-party software extensions which are important for software prototype development. This paper presents a security enhancement plug-in PyXhon, that detects the security vulnerabilities and privacy leaks from third-party extensions. We propose the Function Oriented Analysis, which developers use to monitor all function-call procedures; dynamic Byte Instruction...
With the increasing use of online services that require sharing of information there is a need for Privacy Enhancing Technology tailored for personal information control. Commonly, web privacy is handled through matching of privacy policies and user preferences using software agents on the client side. In this paper, we propose a new approach to privacy policy matching we denote server-side matching...
Protection of privacy is a major concern for users of social web applications, including social networks. Although most online social networks now offer fine-grained controls of information sharing, these are rarely used, both because their use imposes additional burden on the user and because they are too complex for an average user to handle. To mitigate the problem, we propose an intelligent privacy...
The notion of a Personal Smart Space (PSS) offers a new and flexible solution to the problem of implementing pervasive systems. Its attractiveness lies not only in the way in which it bridges the gap between conventional fixed smart spaces and mobile ubiquitous systems, but also in the new functionality it can provide to enhance the user experience. The use of PSSs to realize pervasive systems is...
Privacy in ubiquitous computing is often discussed on a technical level with a focus on cryptography and anonymization. On the other side it is equally important to concentrate on user side aspects of privacy control, i.e., to enable users of ubicomp applications to practice privacy dynamically and in an intuitive way. In our work we review previous approaches on user side management of private information...
Social Network Sites have a number of well publicized privacy issues stemming from the over disclosure of personal information. On one hand, users seem oblivious to their privacy, doing little to protect their personal data. On the other hand, there have been a number of privacy uproars and backlashes due to certain site features or behaviors. In this paper, we explore the privacy issues in social...
