Generating challenge response sets utilizing semantic web technology
First Claim
1. A computer program product for authenticating a user, the computer program product comprising a non-transitory computer readable storage medium having program code embodied therewith, the program code executable by a processor to:
- generate a first question for the user, with the first question requesting the user to select a secret entity;
receive, from the user, an original response identifying the secret entity selected by the user, with the original response corresponding to a valid ontology object included in an ontology database;
query the ontology database to determine a plurality of properties and classes of the valid ontology object corresponding to the secret entity; and
generate, based upon a data generalization strategy using the plurality of properties and classes of the valid ontology object, a generated challenge and response set through the use of semantic web technology so that the generated challenge and response set is related semantically to the original user response and does not directly translate back to the original user response.

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.

2. A computer system for authenticating a user, the computer system comprising:
-
one or more computer processors; one or more non-transitory computer-readable storage media; program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors to; generate a first question for the user, with the first question requesting the user to select a secret entity, receive, from the user, an original response identifying the secret entity selected by the user, with the original response corresponding to a valid ontology object included in an ontology database, query the ontology database to determine a plurality of properties and classes of the valid ontology object corresponding to the secret entity, and generate, based upon a data generalization strategy using the plurality of properties and classes of the valid ontology object, a generated challenge and response set through the use of semantic web technology so that the generated challenge and response set is related semantically to the original user response and does not directly translate back to the original user response. - View Dependent Claims (5, 6)
