Abstract
Abstract A data filtering system is provided that filters data in multiple stages. The system provides a first filter criteria to a first device. The first device uses the first filter criteria to generate a first set of filtered data. The system receives the first set of filtered data from the first device and filters the received data based on a second filter criteria, which is different from the first filter criteria. The filtering of the first set of filtered data generates a second set of filtered data. The first filter criteria and the second filter criteria can be included in a profile data set. The profile data set may be associated with a particular data recipient. The first filter criteria contains public profile data and the second filter criteria contains private profile data. The profile data set may contain data elements associated with a particular class of data recipients or a particular data recipient role. The data filtering system can be implemented such that the first device is an untrusted filtering device and the second device is a trusted filtering device.
