Abstract
An improved technique generates questions to authenticate a user as part of a group. Along these lines, a KBA system, upon receiving a request to authenticate a particular user, collects facts having references to users of the group of users. The collected facts, however, may also include references to users not in the group of users. In building a set of questions for the particular user, the KBA system is capable of favoring facts having references to users of the group of users and few, if any, references to users not in the group of users; conversely, the KBA system is capable of discarding facts having too many references to users not in the group of users. The particular user's responses to the set of questions are indicative of whether the particular user belongs to the group.
