Abstract
In embodiments of the present invention improved capabilities are described for managing digital rights management (DRM) protected content sharing in a networked secure collaborative computer data exchange environment through a secure exchange facility managed by an intermediate organizational entity amongst users of a plurality of other organizational entities, wherein computer data content and access rights for the computer data content is shared between a first and second user, the computer data content and access rights for the computer data content are transformed into a DRM protected computer data content through communications with a DRM engine, wherein the DRM engine is selected based on a content type of the computer data content, and the DRM engine is provided by an entity other than the intermediate organizational entity and other than any of the plurality of other organizational entities.

Abstract
Implementations described and claimed herein provide systems and methods for dynamically masking an access control list corresponding to a file system object in response to a change mode command. In one implementation, a change mode command for a file system object to change a first mode to a second mode is received. The first mode defines a first set of access rights and the second mode defines a second set of access rights. In response to the change mode command, a mask is dynamically applied to an access control list corresponding to the file system object. The access control list has zero or more access control entries defining access permissions for the file system object. The mask modifies any of the zero or more access control entries that have access permissions that exceed the second set of access rights defined by the second mode. The access control list is preserved.
