Erkenntnisse zur Sicherheit

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, approximately 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.

By the same token, many of the anti-privacy „security“ measures we’re seeing — national ID cardswarrantless eavesdroppingmassive data mining and so on — do little to improve, and in some cases harm, security. And government claims of their success are either wrong, or against fake threats.The debate isn’t security versus privacy.

It’s liberty versus control.
