Supporting Collaborative Privacy‐Observant Information Sharing Using RFID‐Tagged Objects

Abstract

RFID technology provides an economically feasible means to embed computing and communication capabilities in numerous physical objects around us, thereby allowing anyone to effortlessly announce and expose varieties of information anywhere at any time. As the technology is increasingly used in everyday environments, there is a heightening tension in the design and shaping of social boundaries in the digitally enhanced real world. Our experiments of RFID-triggered information sharing have identified usability, deployment, and privacy issues of physically based information systems. We discuss awareness issues and cognitive costs in regulating RFID-triggered information flows and propose a framework for privacy-observant RFID applications. The proposed framework supports users' in situ privacy boundary control by allowing users to (1) see how their information is socially disclosed and viewed by others, (2) dynamically negotiate their privacy boundaries, and (3) automate certain information disclosure processes.

Double Cache Approach with Wireless Technology for Preserving User Privacy

“…Most of the healthcare applications use Location Based Services (LBS) for searching points or places of interest like hospitals, health centres, and pharmacies with the help of GPS technology [4][5][6]. This technology plays a significant role in medical emergencies, healthcare applications, and establishing contacts in other domains [7,8]. However, the use of LBS services entails significant risks of breach of user's privacy and security [9,10].…”
