Anonymous and Privacy-Sensitive Collection of Sensed Data in Location-Based Applications (2009)
James Fogarty, Jason I. Hong, Pedram Keyani, Karen P. Tang
Existing approaches to privacy in location-based applications generally treat people as the entity of interest. Anonymity and privacy are then addressed through a fidelity tradeoff, obscuring either...
eWatch: context sensitive system design case study (2008)
Asim Smailagic, Daniel P. Siewiorek, Uwe Maurer, Anthony Rowe, Karen P. Tang
In this paper, we introduce a novel context sensitive system design paradigm. Multiple sensors/ computational architecture, in the form of our eWatch device, is used to infer the activities that the...
