  • Generating challenge response sets utilizing semantic web technology
    Patent number: 9516008
    Abstract: Embodiments of the present invention relate to generating challenge response sets utilizing semantic web technology. In response to detecting an authentication session for a user, a computing device generates a first challenge question that is semantically related to a second challenge question previously responded to by the user, wherein the authentication session seeks to validate an identification of the user. The computing device determines whether a response to the challenge question by the user is valid. In response to determining that the response to the challenge question by the user was valid, the computing device generates a third challenge question or a notification that the response to the challenge question validates the identification of the user.
    Type: Grant
