This U.S.-based research attempts to understand the relationships between users’ perceptions about Internet privacy concerns, the need for government surveillance, government intrusion concerns, and the willingness to disclose personal information required to complete online transactions. We test a theoretical model based on a privacy calculus framework and Asymmetric Information Theory using d...

Technical enhancements of mobile technologies and the pervasive diffusion of mobile devices have radically changed the way in which users communicate and interact. Users stay virtually connected anywhere anytime, and information on their location and mobility is easily available and accessible. As a consequence, new mobile and online applications have been developed, which need the location inf...

iii ABSTRACT Concern about privacy is an important consideration for users of information and communication technologies (ICT), particularly when using computer-mediated communication (CMC), i.e. Internet usage. Several researchers have studied privacy issues by taking into account the views of users to include individuals, organisations, privacy policy makers, governments and trust organisatio...

Social networking sites (SNS) such as Facebook have created a new way for individuals to share personal data and interact with each other on the Internet. The disclosure of this personal data is directly tied to the existing relationships of individuals within an SNS. Individual privacy settings allow a selective disclosure of personal data to specific connected individuals. In this paper, we p...

This paper describes EPFL privacy protection tool for the MediaEval 2014 Visual Privacy task. The goal of the task is to obscure faces, body silhouettes, and personal items of people in the provided surveillance clips to preserve their personal privacy. The EPFL privacy protection tool mainly relies on two privacy protection filters: a warping-based reversible filter to obscure features with lo...

The Standards for Privacy of Individually Identifiable Health Information (Privacy Rule/current rule) took effect on April 14, 2001. As required by the Health Insurance Portability and Accountability Act (HIPAA), the Privacy Rule covers health plans, health care clearinghouses, and those health care providers who conduct certain financial and administrative transactions electronically. Most cov...

Systems dealing with personal information are legally required to satisfy the principle of data minimisation. Privacy-enhancing protocols use cryptographic primitives to minimise the amount of personal information exposed by communication. However, the complexity of these primitives and their interplay makes it hard for noncryptography experts to understand the privacy implications of their use...

Privacy policies, laws, and guidelines have been cultivated based on overly verbose specifications. This article claims that privacy regulations lend themselves to a firmer language based on a model of flow of personal identifiable information. The model specifies a limited number of situations and acts on personal identifiable information. As an application of the model, the model is applied t...

This paper concerns personal privacy and privacy protection in context-aware ubiquitous computing environments. It proposes a privacy ontology solution to facilitate automated processes in privacy control. The development of the privacy ontology is an integrated part of our ongoing effort towards a privacy-respecting middleware solution for context-aware systems.
