摘要： 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. When there is no corresponding behavioral signature plots, multiples nodes are selected for processing of event handlers, and private data are dynamically protected based on behavioral signature plots, so as to assure secure execution results, provide fine-grained protection for security-sensitive behavior and protect data security while maintaining relatively low performance costs.
