D4.2: Set of requirements for interoperability of Identity Management Systems

Importance of interoperability  FIDIS
DEFINITION AND WHAT IS ENABLED
 Ideal scenario of full interoperability

 

Definition and what is enabled

Different definitions are proposed for interoperability in e-commerce. 

 

- Interoperability is the technical connection between systems with the goal to exchange information – on a European level across borders. An interoperable ecommerce eID supported solution is able to work between technologically different systems. Interoperability is a major necessity that ultimately enables identification and authentication of IMS in ecommerce. (Leitold) 

 

- Another definition of interoperability could be that a system can take reliance on the form and contents of another system’s judgment or service outcome. Interoperability of IMS should in the first place rely on the ability of the system to identify and authenticate a given individual. This is particularly important in the field of e-commerce, where individuals have to be identified online or in a remote way.  This functionality to identify persons, however, should be in a given, well-determined and specific way. This should allow using a trusted identity more than once and in several systems (interoperability). In addition, the IMS system should allow for authorisation(s). This would mean that the system should allow for identity and access management. The design of an authorisation functionality, however, is much more complex, but is a factor which may be an enabler of interoperability. (Sel) 

 

- The function of an interoperable IMS should be to enable the user to apply an identity used in one application also to another application. Such systems have compatible authentication mechanisms that are a prerequisite for interoperability.
