摘要： A data leak from a computer can be prevented by intercepting one or more system calls from an unknown application and applying different policies to the intercepted action associated with the system call(s) depending on the data itself and the metadata of a document associated with the system call.
摘要翻译：可以通过拦截来自未知应用的一个或多个系统调用并且根据数据本身和与该系统调用相关联的文档的元数据将不同的策略应用到与系统调用相关联的被拦截的动作来防止来自计算机的数据泄漏系统调用。

摘要： A data leak prevention system includes an application, having source code that is unavailable or non-modifiable, resident on a client device. A system call is emittable by the application as a result of an action, and is to take place before a data leak event can occur. The action involves a document and i) latest full contents of the document, ii) metadata of the document, or iii) a combination of the latest full contents and the metadata. A system call interceptor agent is also resident on the client device. The interceptor agent includes a system call interceptor to intercept the system call emitted by the application and to suspend the system call. The system also includes a policy decision engine to analyze at least some of i) the latest full contents, ii) the metadata, or iii) the combination, and implement a policy action based upon the analysis.
