EARLY ACCESS TO USER-SPECIFIC DATA FOR BEHAVIOR PREDICTION

摘要

A device-indexed data server associates persistent device identifiers of client computing devices with user behavior data devoid of personally identifiable information (?II). User behavior data and PII are aggregated by an off-line data aggregator and associated with non-persistent non-PII user identifiers. Users visiting third party web sites are authenticated by their device identifiers, and identified to the device-indexed data server by the device identifier or by the non-PII user identifier. The device-indexed data server retrieves from the aggregator user behavior data associated with the non-PII user identifier, returns the data to the third party server, and maintains records of user behavior associated with persistent device identifiers without maintaining ?II. Subsequent user visits to any third party server can thereby be customized according to known user behavior without first requiring the user to identify herself.
