Individualization

An individualized application is one whose secret is different from all other applications. With individualized Digital Rights Management (DRM) components, an attack on a Digital Rights Management (DRM) system affects only one application. Content owners can require that their packaged files be played only on an application that has been individualized.
This feature is enforced on the client by the Digital Rights Management (DRM) component in the Windows Media Format SDK. When initializing the DRM component for the first time, a unique value is assigned such that each application is different from the next one. When the license server issues a license, the license created works only for the particular computer with this individualized component.
