Certificate authority

An arrangement for authenticating a user at a service provider is described. The arrangement makes use of the fact that a user of a mobile communication device can be readily and securely identified by a telecommunications provider and re-uses that authentication to identify the same user when accessing the service provider from a different client. The client instructs the mobile communication device to contact an identity provider at the telecommunications provider and shared secrets are exchanged between the identity provider, mobile communication device and client to confirm that the same user is at the client and the mobile communication device.

Authentication to an identity provider

A method of providing data in response to a search request comprises the steps of a social networking website receiving the search request to provide a pseudonym associated with the real name; the social networking website determining that the search request is for a pseudonym which, within its database, is not associated with the real name; the social networking website referring the search request to a identity management server which contains an association between the pseudonym and the real name; the identity management server determining the pseudonym which is associated with the real name; and the identity management server providing an information item which is related to the pseudonym.
