Harvard University and MIT researchers conducted a live test of banking users to measure the effectiveness of browser-based authentication and anti-phishing features earlier this year. The research is scheduled to be presented at the IEEE Symposium on Security and Privacy next month. The tests were done on Microsoft’s IE6 browser and, therefore, did not evaluate effectiveness of the new anti-hacking features in IE7. The researchers did not reveal which site authentication image technology was involved in the test. In the third test, the researchers presented the participants with a “warning page” stating that there was a problem with the target site’s security certificate.”]
