Bank of America's new SiteKey uses shared knowledge to secure transactions on its Web site.

Who goes there?

SiteKey's image and text checks are designed to let people know they are on an authentic Bank of America Web site and also to verify the identity of the customer. The system is being introduced state by state and is expected to be nationwide by the end of this year.
