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 metaphor; research on collection context, e.g., associating multiple RFIDs into "constellations," attached to specific individuals, or otherwise found in recurring groups; 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.

Frequently Asked Questions Why call it the "Sorting Door?" What are RFIDs, and how prevalent are they? How can I tell if items I have have RFIDs in them? If there are RFIDs on objects I own, should I worry? What can I do about RFID tags I don't want?
