As identity theft--and worry about it--burgeons around the world, online services are springing up to fight it. Their advanced tactics, collectively known as identity scoring, go beyond the usual credit monitoring to include online data mining, pattern recognition, even semantic analysis of information about a subscriber that appears on Web pages. The approach is enjoying increasing success in unveiling suspicious activity.

Among the latest firms to join the battle is Garlik, a start-up in Richmond, England. In October 2006 it began offering its "data patrol" service to British residents, 100,000 of whom fell prey to identity theft last year. Garlik combs credit reports, public databases and Web sites for information about customers and presents them with a detailed profile. The portrait allows them to see whether criminals may be trying to use their personal facts to apply for credit cards, take out a loan, or register a fake driver's license or marriage certificate. Four days after Garlik went live at www.garlik.com, more than 10,000 Brits had registered. An annual subscription costs £30 ($59).

Mark Fischetti was a senior editor at Scientific American for nearly 20 years and covered sustainability issues, including climate, environment, energy, and more. He assigned and edited feature articles and news by journalists and scientists and also wrote in those formats. He was founding managing editor of two spin-off magazines: Scientific American Mind and Scientific American Earth 3.0. His 2001 article “Drowning New Orleans” predicted the widespread disaster that a storm like Hurricane Katrina would impose on the city. Fischetti has written as a freelancer for the New York Times, Sports Illustrated, Smithsonian and many other outlets. He co-authored the book Weaving the Web with Tim Berners-Lee, inventor of the World Wide Web, which tells the real story of how the Web was created. He also co-authored The New Killer Diseases with microbiologist Elinor Levy. Fischetti has a physics degree and has twice served as Attaway Fellow in Civic Culture at Centenary College of Louisiana, which awarded him an honorary doctorate. In 2021 he received the American Geophysical Union’s Robert C. Cowen Award for Sustained Achievement in Science Journalism. He has appeared on NBC’s Meet the Press, CNN, the History Channel, NPR News and many radio stations.
