A Framework for Web Science
This text sets out a series of approaches to the analysis and synthesis of the World Wide Web, and other web-like information structures. A comprehensive set of research questions is outlined,Expand
Web science: an interdisciplinary approach to understanding the web
The Web must be studied as an entity in its own right to ensure it keeps flourishing and prevent unanticipated social effects.
Creating a Science of the Web
Understanding and fostering the growth of the World Wide Web, both in engineering and societal terms, will require the development of a new interdisciplinary field.
Information accountability
With access control and encryption no longer capable of protecting privacy, laws and systems are needed that hold people accountable for the misuse of personal information, whether public or secret.
Privacy Tipping Points in Smartphones Privacy Preferences
The results show that participants shared the most when no information about data access or purpose was given, and shared the least when both of these details were specified, while the purpose for data access was solely beneficial to developers. Expand
Using Semantic Web Technologies for Policy Management on the Web
Rein, a policy framework grounded in Semantic Web technologies, is proposed, which leverages the distributed nature and linkability of the Web to provide Web-based policy management and provides an engine for reasoning over these descriptions, both of which can be used to develop domain and policy language specific security systems.

Better the Devil You Know: Exposing the Data Sharing Practices of Smartphone Apps
This mixed methods investigation examines the question of whether revealing key data collection practices of smartphone apps may help people make more informed privacy-related decisions, and designed and prototyped a new class of privacy indicators, called Data Controller Indicators (DCIs), that expose previously hidden information flows out of the apps.

Privacy-Preserving Automated Exposure Notification
This work is among the first to focus on the privacy aspects of automated exposure notification, and introduces two privacy-preserving exposure notification schemes based on proximity detection that provide strong privacy for non-diagnosed individuals and some privacy for diagnosed individuals.

Keys under doormats: mandating insecurity by requiring government access to all data and communications
The damage that could be caused by law enforcement exceptional access requirements would be even greater today than it would have been 20 years ago, and any proposals that alter the security dynamics online should be approached with caution. Expand
Using Dependency Tracking to Provide Explanations for Policy Management
This paper describes the policy approach that provides explanations for policy decisions, provides more efficient and expressive reasoning through the use of nested sub-rules and goal direction, and is grounded in semantic Web technologies. Expand
