Abstract
People now routinely carry radio frequency identification
(RFID) tags – in passports, driver’s licenses, credit cards,
and other identifying cards – where nearby RFID readers
can access privacy-sensitive information on these tags. The
problem is that people are often unaware of security and
privacy risks associated with RFID, likely because the
technology remains largely invisible and uncontrollable for
the individual. To mitigate this problem, we introduce a
collection of novel yet simple and inexpensive tag designs.
Our tags provide reader awareness, where people get
visual, audible, or tactile feedback as tags come into the
range of RFID readers. Our tags also provide information
control, where people can allow or disallow access to the
information stored on the tag by how they touch, orient,
move, press, or illuminate the tag.
