UA Researchers Develop Prototype to Detect Fake Websites

*For their work on detecting fake websites, a UA Eller College of Management research team and a UA alumnus have earned MIS Quarterly’s top award for 2010.

Do you go online to pay bills, shop, transfer funds, sign up for classes, send email or instant messages or search for medical information? If so, then this pertains to you.

Members of a University of Arizona Eller College of Management team and a UA alumnus developed a prototype system to detect fake websites. When tested against other existing commercial systems, the team found that its system resulted in effective and more accurate detections of spoof sites – better than a human can. (more…)
