A privacy-enabled architecture for an RFID-based location monitoring system
James Rafferty Lee, Khalil El‐Khatib · 2009
In large hospitals, location discovery and contact discovery presents possibilities to quickly find someone in an emergency, to narrow the epidemiologic scope of an outbreak, and to reinforce good safety practices. An RFID architecture can make the necessary location data available for knowledge extraction. While people can carry RFID tags to help track their location, their location privacy must also be protected from unauthorized surveillance throughout its collection. This paper proposes a privacy-enabled architecture for an RFID-based hospital location tracing system that prevents network eavesdroppers from tracing a person's location after associating a person to a tag's identifier.
