The Difficulty of Surveillance Crowdsourcing

Internet Eyes is a U.K. startup designed to crowdsource digital surveillance. People pay a small fee to become a “Viewer.” Once they do, they can log onto the site and view live anonymous feeds from surveillance cameras at retail stores.  If they notice someone shoplifting, they can alert the store owner. Viewers get rated on their ability to differentiate real shoplifting from false alarms, can win 1000 pounds if they detect the most shoplifting in some time interval, and otherwise get paid a wage that most likely won’t cover their initial fee.

Fixing a Security Problem Isn’t Always the Right Answer

An unidentified man breached airport security at Newark Airport on Sunday, walking into the secured area through the exit, prompting an evacuation of a terminal and flight delays that continued into the next day. This problem isn’t common, but it happens regularly. The result is always the same, and it’s not obvious that fixing the problem is the right solution.

The Difficulty of Un-Authentication

By Bruce Schneier
In computer security, a lot of effort is spent on the authentication problem.  Whether it’s passwords, secure tokens, secret questions, image mnemonics, or something else, engineers are continually coming up with more complicated — and hopefully more secure — ways for you to prove you are who you say you are over the Internet.

By Bruce Schneier There are several ways two people can divide a piece of cake in half.  One way is to find someone impartial to do it for them.  This works, but it requires another person.  Another way is for one person to divide the piece, and the other person to complain (to the police, a judge, or his parents) if he doesn’t think it’s fair.  This also works, but still requires another person – at least to resolve disputes.  A third way is for one person to do the dividing, and for the other person to choose the half he wants.
