    • The present invention provides methods and apparatuses for obtaining selected metadata from a user device. The user device has a metadata engine that stores and accesses metadata in response to a metadata query. A metadata broker verifies the authenticity of the metadata query from a service provider and returns selected metadata if the service provider has rights to obtain the metadata. The user device has a communications interface that sends a service request that is indicative of the selected service over a communications channel and receives the metadata request that is indicative of the selected metadata. An authorization center receives a metadata request from a service provider, accesses a rule set to determine selected metadata in accordance with predetermined rights, and returns a signed metadata request to the service provider. The signed metadata request has an electronic signature of an authorizing party and is indicative of the selected metadata.
