Abstract
Dynamic security queries are generated based on historical records for purposes of knowledge-based authentication. The dynamic nature of the queries and answers means that once generated, the queries and the answers are exclusively stored in temporary memory (i.e., Random Access Memory (RAM) or the like). As such, the queries and answers are permanently erased from RAM after they have been presented to the user or, at a maximum, are erased from RAM once the computing session is terminated. Moreover, since the queries/answers are determined from dynamic user-specific datasets compiled at the time of authentication, the present invention is able to generate knowledge-based queries that are not capable of identification by other parties from any level of personal record searching.
