Abstract: The invention relates to a behavior data analysis method and device. The abovementioned method includes monitoring operation behavior executed by a target application program; collecting behavior data generated by the target application program according to the operation behavior; judging whether the operation behavior is sensitive behavior according to the behavior data; if the operation behavior is sensitive behavior, extracting behavior characteristics in the behavior data; obtaining historical behavior record information associated with the operation behavior; analyzing the behavior characteristics according to the historical behavior record information, and judging whether the operation behavior is suspicious behavior according to an analysis result; and if the operation behavior is suspicious behavior, sending an identity verification instruction to the target application program. The abovementioned behavior data analysis method and device can effectively guarantee personal property safety of users on a terminal, and improve security.
