METHOD FOR CONTROL OF PERSONAL DATA

摘要

The invention relates to end user controlled handling of personal data on e.g. the Internet. Web services are offered in a controlled manner from a service broker ( 250 ) provided with appropriate security mechanisms. The broker contains end user controlled policies related to personal data/services, while the actual data is arranged at different locations in the network. Web service information is published in an open registry ( 256 ) at the broker. When an application provider ( 220 ) finds a desired service in the registry, its service request is guided to the appropriate service broker. The broker returns the policy for the requested service, whereafter the service provider ( 240 ) can be contacted, preferably through an encapsulated SOAP message. A preferred embodiment performs common sign on authentication when a new application is contacted.
