A METHOD AND ARRANGEMENT FOR PROVIDING SECURITY FOR CONTENT PURCHASES.

摘要

A method and arrangement for providing security when an IMS client (A) purchases content from a content or service provider (404), the IMS client having a unique IMS identity (IDA) registered with a first IMS operator (400). A second IMS operator (406) assigns a unique IMS identity (IDc) to the content or service provider which is authenticated based on the assigned IMS identity. The validity of the IMS client is then verified towards the content or service provider, based on a mutual interconnect agreement between the first and second IMS operators, in response to a purchase request from the IMS client. The content or service provider can then also be validated towards the IMS client.
