Method, apparatus and computer program for providing access to identity services of users. A Discovery Service DS server (100) stores for a set of users references (RO1A,ROnB) of identity services (IDSRV-A,IDSRV-B) available for them and usable to contact respectively with the Service Providers SPs (120,130) hosting each of said identity services. For a given identity service not yet registered for a given user, the DS server selects a SP (140) that is able to provide it, and stores a new resource offering (RO2X) that corresponds to the registration of said identity service. For selecting the appropriate SP, the DS server can check a service capability storage (103-2,301) that comprises information about what identity service(s) can be provided by a given SP, and which can be dynamically updated from SPs with the identity services they respectively support. The DS server can contact the user to collect SP preferences and/or service data. |
