USC student's computer program enlisted in security efforts at LAX

Program developed by a USC student is intended to thwart terrorists by making the frequency of searches unpredictable.

The doctoral dissertation of a 26-year-old USC computer science student is having an unusual effect on security and transportation at Los Angeles International Airport.

That's because the LAX police are giving a trial run to a new computer program that, they say, seeks to keep potential terrorists and criminals constantly uncertain about where, when and how often vehicles will be searched at airport entrances. The software is based on the thesis of Praveen Paruchuri, who earned his doctorate in May.
