RFID tag

Researcher Nicolai Marquardt is working on technology he hopes will be able to control RFID tags and protect private information.


Technology for providing alerts when information on radio-frequency identification (RFID) tags is being accessed and controlling access to private information was on display during the recent CHI 2010 conference.

Working with Microsoft Research, Nicolai Marquardt, a Ph.D. student at the University of Calgary, has developed four prototype RFID controller groups. The first group provides direct feedback to users by either lighting up, vibrating, or making a sound when the tag is being accessed. The next group features controllable tags, including a button that has to be pressed to activate the RFID and a touch sensitive tag that has to be held to read its information. In the third group, one tag is light sensitive and prevents data from being accessed when the RFID card is in a pocket, and the other tag is tilt sensitive and can only be accessed when pressed flat against a reader. The fourth group makes some information on an RFID tag always accessible, but more private information can only be accessed by moving the tag closer to the reader.
