Abstract: A method for providing subscriber data from a first service provider network to a content provider external to the service provider network comprises receiving a first network identifier sent from a subscriber device that is authenticated to communicate over the first service provider network, wherein the first network identifier is sent by the subscriber device in a first message to an entity outside of the service provider network; receiving a second network identifier sent from the subscriber device to the first service provider network; performing a verification process using the first network identifier and the second network identifier to verify whether it is permissible for subscriber data stored at the service provider network to be provided to the content provider external to the service provider network. In response to the verification process being successful, the subscriber data is provided to an entity that is external to the service provider network.

Abstract: A method comprises, for a first instance of user engagement with a content provider, and at a first entity within a service provider network, receiving a first message comprising a first ID associated with the provision of content from the content provider; identifying the subscriber and determining an identifier for the subscriber; and transmitting the identifier for the subscriber and the first ID to a second entity. The first ID is stored in association with the identifier for the subscriber. This is repeated for a second instance based on the receipt of a second message comprising a second ID from the or another subscriber device of the subscriber. The second ID is stored with the subscriber identifier and thereby with the first ID. Information indicating the stored association is provided to the content provider, thereby to allow the content provider to associate the first instance with the second instance.
