LA Airport Uses Random Numbers To Catch Terrorists

Posted by CmdrTaco on from the better-than-searching-me-whenever-i-have-a-beard dept.

An anonymous reader writes "Los Angeles International Airport (LAX) is using randomization software to determine the location and timing of security checkpoints and patrols. The theory is that random security will make it impossible for terrorists to predict the actions of security forces. The ARMOR software, written by computer scientists at the University of Southern California, was initially developed to solve a problem in game theory. Doctoral student Praveen Paruchuri wrote algorithms on how an agent should react to an opponent who has perfect information about the agent's choices."

      On a similar vein:

      int numCheckpointsToday()
      {
                return 0; // This is a random number chosen by a fair method
      }

    They are going to create a huge grassroots information and education campaign against this. They believe the security should intelligently designed and should not depend on random chance of security people and the bad guys coming together.
