Abstract
A pluggable file-based DRM (digital rights management) API (application program interface) layer for applications and engines. The invention defines a pluggable file-based DRM API layer such that mobile operators can choose to use any file-based DRM (FDRM) engine in their final product. An FDRM engine can be content agnostic (e.g., can range from an executable to a media file or ring-tone). In accordance with the invention, an application can become DRM aware by calling the novel file-based DRM APIs. Any FDRM engine can be plugged into the novel API layer such that applications can use the protected content. The API layer of the subject invention can be designed such that applications that are DRM aware by using the file-based DRM API layer can be DRM engine agnostic.
