The Department of Homeland Security's $10 billion system for using fingerprints to check the identity of foreign visitors has only about a 50-50
chance of catching suspected terrorists, even if their prints are on file, according to a mathematical analysis in a peer-reviewed scientific journal.
The Proceedings of the National Academy of Sciences carried the analysis, which used statistical modeling to predict how often the inkless finger
scans collected from visitors to the United States can be successfully matched with the type of poor-quality images that are typically the only
records of the fingerprints of terrorist suspects.
"The strong dependence of biometric identification performance on image quality level leaves the ... program vulnerable to exploitation by
terrorists," said the journal.

Meanwhile Homeland Security defends the Biometric Systems technology stating that their assumptions in the flaw of the system are purely theoretical
and only examines the system under the worst possible scenario.
