What Our Top Spy Doesn't Get: Security and Privacy Aren't Opposites

Bruce Schneier is certainly someone to take seriously in the security arena...

What Our Top Spy Doesn't Get: Security and Privacy Aren't Opposites: "Security and privacy are not opposite ends of a seesaw; you don't have to accept less of one to get more of the other. Think of a door lock, a burglar alarm and a tall fence. Think of guns, anti-counterfeiting measures on currency and that dumb liquid ban at airports. Security affects privacy only when it's based on identity, and there are limitations to that sort of approach.

Since 9/11, two -- or maybe three -- things have potentially improved airline security: reinforcing the cockpit doors, passengers realizing they have to fight back and -- possibly -- sky marshals. Everything else -- all the security measures that affect privacy -- is just security theater and a waste of effort."
