Sharing of authenticated data

摘要

This invention relates to methods and apparatus for sharing of authenticated data. The invention relates particularly to sharing of location information data from a certified source. The method of sending authenticated data from a sender to a third party comprises the steps of: determining data associated with a communication session initiated by a user, the data being unauthenticated; sending the unauthenticated data to an intermediary to give rise to authenticated data, the intermediary having an authentication arrangement with the third party and a relationship with the sender; receiving the authenticated data from the intermediary in dependence on the relationship; and sending the authenticated data to the third party.
