USER IDENTITY DETERMINATION METHOD AND DEVICE

摘要

Disclosed are a user identity determination method and device. The method includes: counting whether the number of short messages sent by a user within a rule duration meets a traffic threshold (S102); if yes, counting the failure rate when the user issues a short message for the first time within the rule duration (S104); and if the failure rate meets a ratio-monitoring threshold, then determining the user as a blacklist user (S106). The present invention solves the problem that the policy for capturing a suspicious user is too simple and there are contradictions in recall ratio and precision ration, improving the overall performance of the short message monitoring system.
