"For anybody concerned about #privacy and surveillance, and interested in how the use of such technologies is implemented and regulated, EFF's Street Level Surveillance hub offers a handy resource. Instead of wondering just what biometric surveillance is, you can quickly look it up and be simultaneously informed and creeped out by discovering that it "encompasses a collection of methods for tracking individuals using physical or biological characteristics, ranging from fingerprint and DNA collection to gait recognition and heartbeat tracking.""

It'd be interesting to see international versions of this pop up, not just one for the U.S. (although, this is still important work).
