摘要
Systems and methods for identifying a weak stimulus in a stimulus-based authentication system is provided. Counters are associated with each stimulus used in the authentication and a first counter is incremented when the stimulus is used in an authentication session and a second counter is incremented when a successful event occurs with respect to the stimulus during the authentication session, but the authentication session ultimately fails. A ratio of the second counter and the first counter is compared to a threshold and the stimulus is identified as weak when the ratio exceeds the threshold. The stimulus may then be removed and no longer be used in the stimulus-based authentication system.
