Research Aims to Detect Online Terrorist Activity

Once the federal government contract details are set, researchers at four universities will begin trolling the Web for early signs of terrorist activity.

January 01, 2007 — CSO — Once the federal government contract details are set, researchers at four universities will begin trolling the Web for early signs of terrorist activity.

Rutgers, the State University of New Jersey; the University of Southern California; the University of Illinois at Urbana-Champaign; and the University of Pittsburgh are working on a $10.2 million project to

research methods for detecting online terrorism activity.

In July 2006 the Department of Homeland Security announced the three-year grant to the four

universities to advance information analysis and computational technologies.

Fred Roberts, director of the Center for Discrete Mathematics and Theoretical Computer Science at Rutgers, says researchers hope to develop algorithms that will find patterns and relationships in such

public sources as news stories and blogs to determine authorship, even when a writer tries to hide his identity. Researchers' methods will include mathematics graph theory, dynamic data analysis,

optimization, "machine learning" and statistical analysis. Each university has its own set of partners; for example, Rutgers' collaborators include AT&T Labs, Bell Labs and Rensselaer Polytechnic Institute.

Privacy concerns about the research project have been voiced in the blogosphere. ShadowMonkey, a blogger who has a "DHS Watch," questioned the project after it was announced in July: "If you're writing

on the Net using a pseudonym, are you going to be placed on a watch list?"

Roberts says that "protecting privacy is part of the research agenda." Safeguards will include

anonymizing data, using only publicly available sources and adhering to data handling protocols

created by a privacy officer.

Besides privacy, the project will tackle many challenges along the way, such as the vast amount of

information with changing sources and how quickly information flows over the Web. In order to

evaluate potential terrorist activity, the researchers must develop technologies to rate consistency and

reliability of the sources of information. Researchers are currently finalizing contracts with DHS.
