The Sorting Door Project
The Sorting Door Project is an exploration of issues around Radio
Frequency Identification (RFID), including of surveillance and privacy;
unique identification; and classification.
RFID technologies will introduce new stresses in the tension between
personal privacy, and information collection and analysis.
The Sorting Door is intended as a testbed for technologies and policies
to address issues raised by RFID.
The elements of the Sorting Door include:
- research on interrogation of RFIDs "in the wild," using the Door
(or, actually, any number of instrumented collection points) as a
- research on collection context, e.g., associating multiple RFIDs into
"constellations," attached to specific individuals, or otherwise found in
- research on constructing associations, over time;
- research on using object type information to make "educated guesses"
as to identity, whether unique, or as part of various classes.
