摘要
An improved technique involves adjusting the operation of a KBA system based on facts that may contain information known to an adversary. Along these lines, the KBA system may receive an alert concerning an adversary that may know the answers to some of the KBA questions used by the KBA system in authenticating users. In response to alert, the KBA system may alter operations in order to account for the adversary. Subsequently, when a user requests authentication, the KBA system selects KBA questions based on adjustments made to the KBA system in order to avoid presenting the adversary with KBA questions derived from facts (s)he knows.
