    • A server computer queries a client device using a test fingerprint that does not correspond to any document stored in the client device, and restricts access by the client device to the server computer if the query result is incorrect. In some implementations, the server selects a set of first fingerprints associated with documents stored in the client device, generates a set of test fingerprints, none of which are associated with any document stored in the client device, and queries the client device using fingerprints from the set of first fingerprints and the set of test fingerprints to produce query results. The server computer restricts access by the client device to the server computer if at least one of the query results is incorrect, and enables the client device to access the server computer if at least a predefined number of the query results are correct and none are incorrect.
    • 服务器计算机使用与客户端设备中存储的任何文档不对应的测试指纹查询客户端设备,如果查询结果不正确,则会将客户端设备访问限制到服务器计算机。 在一些实现中,服务器选择与存储在客户端设备中的文档相关联的一组第一指纹,生成一组测试指纹,其中没有一个与存储在客户端设备中的任何文档相关联,并且使用来自 第一组指纹集和一组测试指纹产生查询结果。 如果至少一个查询结果不正确,则服务器计算机将客户端设备访问服务器计算机,并且如果至少预定义数量的查询结果正确且没有错误,则客户端设备可以访问服务器计算机 。
