    摘要： To provide secure single-source panel audience measurement data while providing confidentiality and security of panel membership, an audience measurement server may capture content identifiers and client identifiers of devices receiving content. A panel provider may generate a probabilistic data structure via a hash of the client identifiers. The audience measurement server may utilize the filter array to extract a subset of measurement data including the data of the panel members, as well as data of some non-panel members as false positives, without being able to distinguish between the members and non-members. The audience measurement server may encrypt the extracted subset of data with each client identifier corresponding to an item of data as a key, and send the encrypted data to the panel provider, thus including both panel and some non-panel data, with the panel provider only able to decrypt data corresponding to its own panel members.

    摘要翻译： 为了提供安全的单源面板观众测量数据，同时提供面板成员资格的机密性和安全性，观众测量服务器可以捕获接收内容的设备的内容标识符和客户端标识符。 面板提供商可以通过客户端标识符的散列来生成概率数据结构。 观众测量服务器可以使用过滤器阵列来提取包括小组成员的数据的测量数据的子集以及一些非小组成员的数据作为误报，而不能区分成员和非成员 。 观众测量服务器可以使用与数据项对应的每个客户标识符作为密钥对所提取的数据子集进行加密，并且将加密数据发送到面板提供商，从而将面板和一些非面板数据同面板提供商 只能解密对应于自己的面板成员的数据。

    摘要： A method for providing efficient and accurate estimates of TV viewership ratings through a distributed computer system that includes multiple computers is disclosed. The method includes: receiving a query from a client at the distributed computer system; dynamically selecting one or more computers according to a predefined sharding function; at each of the selected computers, determining a count of qualified event records that satisfy the query; aggregating the respective counts of qualified event records determined by the selected computers; statistically projecting the aggregated count of qualified event records into an estimated total count of qualified event records on the distributed computer system; and returning the estimated total count of qualified event records to the requesting client.
