Almost everything we do leaves a digital trace, be it sending an email or purchasing something online. Irad Ben-Gal, Eugene Kagan and doctoral student Aviv Gruber of the department of industrial engineering in Tel Aviv University's Ibi and Aladar Fleischman of the faculty of engineering are using these digital traces to track criminals and strengthen homeland security against terrorist threats.
According to a release, the researchers are developing high-powered, context-based search algorithms to analyse digital data on the fly. With the ability to process new pieces of information instantly, these algorithms move at a high speed to support ongoing investigations. This research was recently presented at the Convention of the Institute for Electrical and Electronic Engineers in Israel, and the details of the algorithms would soon be published in the journal Quality Technology & Quantitative Management.
Ben-Gal and his fellow researchers work with leading companies in homeland security on how to establish patterns of terrorist or criminal activity using communication files.
