User Authentication Subsystem

The User Authentication Subsystem confirms the identify of a user. From the data infrastructure perspective, it is only composed of an authentication service object.

Computational Model for the User Authentication Subsystem

The User Authentication Service is a proxy object for all actions needed to verify the identity of a user. It supports the following interactions:

• authenticate user (server). Public interface for determining whether the agent is who it claims to be.

• request user attributes (server). Public interface for requesting provided attributes from the agent.

Note that the registration of users is not considered to be part of the data infrastructure, as it is covered by the organisational infrastructure of the employers of the user.
