Abstract
A user authentication system includes a dialogue manager adapted to prompt the user with multiple, selectable pass-phrases. A selection recognizer recognizes user selection of at least one of the multiple, selectable pass-phrases. A user identity analysis module analyzes one or more potential user identities based on adherence of user selection of the pass-phrase to predetermined pass-phrase selection criteria assigned one or more enrolled users.
