Abstract

An improved software application for digital rights management, providing the means to control the interaction between a client'"'"'s computer/monitor and a remote server on which the present invention and the creative work of an author/inventor reside, is herein disclosed. A key aspect of the present invention is the series of applets that selectively disable certain functions (e.g. “Save File”, “Print File”, “Download File”, “Print Screen”, copy/save to “Clipboard”) contained in most existing browsers. Any attempt to use one of these functions results in, at least, the disabling of the feature and/or the display of an error message. Other features include certain e-commerce functions and encryption of data passed between the remote server and the client machine. In this manner, the information (i.e. text and images) resident on the client'"'"'s browser running the software application according to the present invention is thereby protected from misuse/misappropriation. While the primary purpose underlying the present invention is the protection of creative works of authorship/inventorship, the software application also contains features that provide the client with some degree of control over the manner in which the information is displayed on his/her monitor.

Claims

1. A system for providing managerial control over access rights to digital information, comprising a reader applet that is executable when a client attempts to view selected remote content in a browser window, the applet controlling the client'"'"'s ability to use certain standard computer functions from among the group including “

Save File”

, “

Print File”

, “

Download File”

, “

Print Screen”

, “

Copy/save to Clipboard”

.

2. The system for providing managerial control over access rights to digital information according to claim 1, wherein said reader applet recognizes when the client is attempting to access one of said functions while viewing/reviewing the remote content and transmits/displays an error message on the client'"'"'s screen, and also sends an alert message to the remote web server to notify the system administrator of the client'"'"'s actions.

3. The system for providing managerial control over access rights to digital information according to claim 1, wherein said reader applet provides limited or one-time-use access to selected remote content by writing a cookie to the client'"'"'s computer to record each viewing of remote content, and said reader applet recognizes the deletion and attempted deletion of cookies by any user that seeks to obtain multiple-use access to said remote content.

4. The system for providing managerial control over access rights to digital information according to claim 1, wherein all remote content transmitted to the reader applet on the client'"'"'s computer is encrypted by the remote server and decrypted by the reader applet for display on the client'"'"'s computer/monitor.

5. The system for providing managerial control over access rights to digital information according to claim 1, wherein said reader applet maintains keyboard focus to prevent a client from utilizing third party programs to save or print protected content.

6. The system for providing managerial control over access rights to digital information according to claim 1, wherein said reader applet includes a bookmarking function that allows a client to return to the point where he/she left off in a partially-read document.

7. A system for providing managerial control over access rights to digital information, comprising:

a text reader applet, which is executable when a client attempts to view a remote text document in a browser window, for controlling the client'"'"'s ability to use standard computer functions among the group comprising “

Save File”

, “

Print File”

, “

Download File”

, “

Print Screen”

, “

Copy/save to Clipboard”

;

an image reader applet, which is executable when a client attempts to view a remote image in a browser window, for controlling the client'"'"'s ability to use standard computer functions among the group comprising “

Save File”

, “

Print File”

, “

Download File”

, “

Print Screen”

, “

Copy/save to Clipboard”

;

an image editor applet, which is executable when a client attempts to edit a remote image in a browser window, for controlling the client'"'"'s ability to edit said image.
