Abstract
The invention relates to a system of obtaining authorization where there are multiple authorization modules. When an authorization is provided by a module, it is combined with a security token, digital signature or encryption identifying which module provided the authorization. To obtain a full authorization, multiple authorization modules may be required and these modules can be connected in parallel and or in series with each other.
