Dynamic file access control and management
First Claim
1. A dynamic file access control and management system configured to access one or more content sources including a set of files, said system comprising:
- A. a proxy system linked to said one or more content sources, said proxy system comprising an access control module configured to selectively obtain a file from said content sources as a function of an authorization of a user requesting said file and a set of access policies;
B. a rights management module configured to generate a set of usage rights associated with said file as a function of a set of predefined usage policies associated with said file for said user;
C. at least one client device having a client module configured to interface to a client operating system, said client module configured to selectively inhibit operating system functions with respect to said file as a function of said usage rights; and
D. one or more communication means, via which said file and said usage rights are provided to said client device.

Abstract
A dynamic file access control and management system and method in accordance with the present invention may be a proxy file management system that includes one or more file system proxy servers that provide selective access and usage management to files available from one or more file systems or sources. The present invention may embody a secure transport protocol that tunnels distributed file systems, application independent usage controls connected to files on end-user computers, dynamically merging secondary content to a requested file, and applying bandwidth management to any of the foregoing. Embodied in the various implementations of the present invention is enhanced file security. Preferably, the proxy file management system is transparent to an end-user. A dynamic content management system may also be included that selectively adds content to requested files.
