Abstract: User events of a platform are processed to extract aggregate information about users of the platform at an event processing system. A query relating to the user events is received at the system and at least one query parameter is determined from the query. Various privacy controls are disclosed for ensuring that any information released in response to the query cannot be used to identify users individually or to infer information about individual users.

Abstract: This disclosure relates to the processing of user events. In particular, it addresses various problems relating to the augmentation of a user event—received in a data stream of sequenced events—with data of one or more cooperating reference data items. For example, the augmented user events may be stored in an index on which queries can be run in real-time to extract aggregate and preferably anonymized information from those events according to the queries. Other example use-cases are also disclosed.

Abstract: A system for processing user events of a platform having a plurality of users comprises: a customer data interface configured to receive from a customer management system customer data and release authorization data for the customer data; an input configured to receive user events of the platform, each comprising an identifier of at least one of the users; an attribute manager configured to determine, for the users of the platform, user attributes of a first type from user data of the platform and user attributes of a second type from the customer data; a query handler configured to respond to submitted queries by selectively releasing aggregate information related to user events; and a processing component configured to process the user events and the user attributes to extract the aggregate event-related information for release.
