Abstract: The present invention involves with a cloud tenant oriented method and system for protecting privacy data. The method comprises at least the following steps: analyzing event handler information and/or behavioral signature information of request information and determining an execution mode, selecting at least one node without a behavioral signature plot to execute the tenant request and recording an execution result, generating a behavioral signature plot based on the execution result, and dynamically detecting security-sensitive behavior based on the behavioral signature plot. The present invention ensures data security during processing of security-sensitive data for cloud services by adopting a technology based on behavioral signatures, and prevents attackers from exploiting vulnerabilities and bypassing security control to conduct malicious operations.
