<p>An electronic document protection system consists of a source (100) in which a protection flag (130) is associated with a file (120) by a first protection component (140) to define a level of protection for the file. The electronic documentation system also has a destination which includes an operating system (160), an application program (170) and a second protection component (150) that interfaces with the operating system. At the destination, the second protection component reads the protection flag and communicates it to the operating system and the application program. Selected functionalities of the operating system and the application program at the destination are enabled or disabled in response to the communication from the second protection component.</p> |
