Abstract

See full text

File system interaction with digital rights management (DRM) is facilitated by enabling one or more file system components to be DRM-aware. These one or more file system components may be part of a computer operating system. An exemplary system implementation includes: one or more processors; and one or more media in operative communication therewith, the media storing one or more file system components that are configured to provide content having DRM controls to a requesting program in either a raw form or a decrypted form in dependence on whether the DRM controls comprise simple DRM content controls or complex DRM content controls. In another exemplary system implementation, the one or more file system components are configured to provide files with simple DRM content controls to requesting applications in a decrypted form and to provide files with complex DRM content controls to requesting applications in an unaltered form.
