Today we continue to discuss some more of the authentication and authorization frameworks. In particular, we look at information rights management process such as in Oracle IRM. The process involved is as follows:
An author creates a document or an email on her desktop or notebook.
The document is sealed by the author when she publishes it. The document is then sent to the receiver
The receiver click on the document. The document is encrypted and cannot be opened without an installed IRM application. If the application is available, it can then be decrypted and shown to the receiver.
The components involved in this process include:
- an identity manager to centrally provision IRM users and entitlements.
 - a virtual directory to synchronize IRM users and groups
 - a Single sign on for desktop single sign on.
All user interfaces are consistent through out the users use of the applications and built on the same platform framework. The users have a seamless and familiar interface for access management. The identity management is provided by the Oracle Identity Manager. The identity management architecture is built on  a data tier that supports an operational db, an ID store, and an audit DB.  The Oracle web logic server is the layer above the data tier. This layer is responsible for all of domain template management, configurations, and installing, upgrading and patching.  The weblogic server maintains a unified, consolidated and consistent view over the ID store which includes membership providers such as Active Directory. The layer above the web logic server is the Fusion middleware services provides such functionality as
the ability to configure new metadata models
to provision new users or export user information to other systems
for users to administer their own profiles with fine grained entitlements
for policy management based on profiles
for creating and provisioning workflows that enables automation of IT tasks along with a Workflow visualizer and a designer.
a password management that includes self-service.
and audit and compliance management
