摘要： Recommendation systems are widely used in Internet applications. In current recommendation systems, users only play a passive role and have limited control over the recommendation generation process. As a result, there is often considerable mismatch between the recommendations made by these systems and the actual user interests, which are fine-grained and constantly evolving. With a user-powered distributed recommendation architecture, individual users can flexibly define fine-grained communities of interest in a declarative fashion and obtain recommendations accurately tailored to their interests by aggregating opinions of users in such communities. By combining a progressive sampling technique with data perturbation methods, the recommendation system is both scalable and privacy-preserving.

摘要翻译：推荐系统广泛应用于互联网应用。在目前的推荐系统中，用户只能发挥被动的作用，对推荐生成过程的控制有限。因此，这些系统提出的建议和实际用户兴趣之间经常存在很大的不匹配，这些建议是细粒度和不断发展的。通过用户分配的推荐体系结构，个人用户可以灵活地定义精细的社区，并以声明方式定义感兴趣的社区，通过汇总用户在这些社区的意见，获得准确定制的兴趣建议。通过将逐行采样技术与数据扰动方法相结合，推荐系统既可扩展又保密。

摘要： Aspects of the subject disclosure may include, for example, a non-transitory, machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations including receiving a call; selecting a next carrier to handoff the call; generating a call data record (CDR) for the handoff to the next carrier; encrypting the CDR using a call encryption key, thereby creating an encrypted CDR; encrypting the encrypted CDR using a committee encryption key, thereby creating a double encrypted CDR; recording the double encrypted CDR to a blockchain; and sending the call encryption key to the next carrier. Other embodiments are disclosed.

摘要： In embodiments of the disclosed technology, indexes, such as inverted indexes, are updated only as necessary to guarantee answer precision within predefined thresholds which are determined with little cost in comparison to the updates of the indexes themselves. With the present technology, a batch of daily updates can be processed in a matter of minutes, rather than a few hours for rebuilding an index, and a query may be answered with assurances that the results are accurate or within a threshold of accuracy.
摘要翻译：在所公开的技术的实施例中，诸如反向索引之类的索引仅在必要时被更新以保证在与索引本身的更新相比较较少成本的预定阈值内的应答精度。使用本技术，可以在几分钟内处理一批每日更新，而不是几个小时来重建索引，并且可以回答保证结果准确或准确的阈值。

摘要： Concepts and technologies disclosed herein are for managing opt-in and opt-out for private data access. According to one aspect disclosed herein, a mobile device can receive a request to obtain private data associated with a user of the mobile device and, in response to the request, determine whether an application program associated with the request is permitted to access the private data based upon a rule. The mobile device, in response to determining that the application program is permitted to access the private data based upon the rule, can instruct the application program to proceed to obtain the private data. The mobile device, in response to determining that the application program is not permitted to access the private data based upon the rule, can instruct the application program to avoid obtaining the private data.

摘要： The present disclosure is directed to systems, methods, and computer-readable storage media for anonymizing data over multiple temporal releases. Data is received, and nodes and connections in the data are identified. The data also is analyzed to identify predicted connections. The nodes, the connections, and the predicted connections are analyzed to determine how to group the nodes in the data. The data is published, and the grouping of the nodes is extended to subsequent temporal releases of the data, the nodes of which are grouped in accordance with the grouping used with the data.
