Real time tracking more enabled by new industry standard

The recently approved standard in February 2012 from the Institute of Electrical and Electronics Engineers (IEEE) IEEE 802.15.4f enabled Zebra Technologies to develop RFID tags, sold to West Cheshire College for tracking its students.

As reported in the RFID Journal, [NB. This RFID Journal article was withdrawn from the RFID Journal’s website w/c 7 Jan 2013.  A Copy of the article (pdf) is here and here is the original article on the Internet Archieve Wayback MachineZebra “In anticipation of that development [IEEE 802.15f], Zebra Technologies has announced a new version of its Dart ultra-wideband (UWB) real-time location system (RTLS) sensor that will be compatible with that standard

With no regulations of the tracking of humans – students in this case – by RFID in the UK it seems that students at least, as education becomes more corporate and finance driven, have this real time location system tracking to look forward to.

Much like how biometrics were trialed and introduced in schools in the UK from 2001-2012, completely unregulated, not informing parents, government having no knowledge of what the biometric industry was up to in its schools, it appears that RTLS RFID now is being afforded the same luxury.

According to the RFID Journal  [NB. This RFID Journal article was withdrawn from the RFID Journal’s website w/c 7 Jan 2013.  A Copy of the article (pdf) is here and here is the original article on the Internet Archieve Wayback Machinethese are the characteristics of RFID tags the students wear:

  • UWB tags emit brief RF signals across the entire 6.35 to 6.75 GHz frequency band.
  • Average battery lifespan of a tag is seven years.
  • Receivers, which can receive tag signals from up to 328 feet away, located throughout the campus buildings, in order to ensure that the tags can be pinpointed no matter where within the school a student might be located.  (Toilet? Showers?)
  • Designed to provide accuracy greater than 1 meter (3.3 feet).
  • Transmission rate of once per second.
  • Enables observation of student and staff in peer groups.

The standard IEEE 802.15f was approved February 2012.  RFID Journal article of 30 April 2012 states that “The school deployed the technology in two phases—first at its Chester Campus, in 2010, and then at its newly built Ellesmere Port Campus, last year [2011]”

…mmm has the college been trialing RTLS before the standard was set?

Transparent RFID policy and consent

In January 2011 the EU document ‘Privacy and Data Protection Impact Assessment Framework for RFID Applications’ was published. The document is an industry-prepared framework for Personal Data and Privacy Impact Assessments of RFID Applications and endorsed by the Article 29 Data Protection Working Party.

RFID Privacy targets include “Compliance with the data subject’s right to object –  It must be ensured that the data subject’s data is no longer processed if he or she objects.” along with one of the concerns of the privacy risks being Invalidation of explicit consentConsent has been obtained under threat of disadvantage.” – see pages 13 and 15.   However, this EU document is only advisory and simply details good practice with no set enforcable regulated code of practice yet in place for RFID tracking people.

In a recent article it came to light that in the UK a 14-19 college, West Cheshire College, are using RFID tags for registration purposes but then oddly state the information the RFID give them will be anonymised.  Quite how they plan to register individual students with anonymised RFID tags is baffling but, more worryingly, the college seems to have adopted a ‘must wear’ attitude.

In order for students to be able to object, as detailed the above EU document, to this level of surveillance, where staff at educational establishments such as West Cheshire College are able to  “look at them in groups, such as peer groups.”, both students and staff tagged need to be fully informed of exactly what the RFID chips they carry are being used for. i.e. how and where people would be tracked and the personal information held.

rfidcctvsignThis communication of the college’s intent of RFID use to register its students and staff, and subsequent consent, presumably would need a little more than a verbal statement.  Indeed, a document detailing the college’s RFID policy and a Privacy Impact Assessment would surely be considered good practice.

Maybe an adoption of the CCTV industry’s code to inform persons of CCTV tracking by signage on walls in areas where surveillance is occurring should be considered where RFID real-time location systems are in operation?

This would go some way to ensure transparency for those choosing to carry RFID tags.
