Abstract
An improved technique involves generating KBA questions based on facts from fact sources pointed to by an activity log. A KBA system obtains an activity log from a computer of a user in an organization. For example, the computer records the user's web browsing history. The KBA system then considers each entry in the activity log as a source of facts for deriving KBA questions. In the case of a web browsing history, the KBA system generates facts from web pages that the user visited. The KBA system then derives new KBA questions from the facts so derived.
