Abstract

The invention provides a method and system for presenting infromation in a web document using a program applet to restrict further copying or redistribution. The web document includes a first region in which a graphical element or other information is displayed, and a second region covering the first region in which a program applet is invoked by a server for the web document. The program applet is dynamically created upon access, and assigned a serial number. The program applet contacts the server for permission to display the graphical element or other information; thus, the server can control, by granting or denying permission, when and if the program applet displays the graphical or other information. The program applet can be subjected by the server to one or more of a variety of restrictions, such as: a limit on the number of times the information is displayed, a time limit, a requirement for a password or other security authentication, a requirement that the program applet is executing at a selected device or from a selected web document, or other requirements the server may deem fit to impose.

Claims

1. A method, including the steps of

presenting a web document from a web server to a web client, said web document including a first region associated with a set of further information;

generating a program applet in response to selection of said first region, said program applet being disposed to present said further information only upon selected conditions; and

transmitting said program applet to said web client.

2. A method as in claim 1, wherein said further information includes more detailed graphical information.

3. A method as in claim 1, wherein said further information includes access to a database.

4. A method as in claim 1, wherein said selected conditions include a selected number of times for presenting said further information, a selected period of time for presenting said further information, a requirement for presentation of selected authentication by said user, a requirement that the program applet is executing at a selected device or from a selected web document.

5. A method as in claim 1, wherein said selected conditions include a selected type of presentation of said further information.

6. A method as in claim 1, wherein

said program applet includes a unique ID;

said program applet attempts confirmation of said selected conditions with said web server at selected times; and

said program applet refuses to present said further information without said confirmation being successful.

7. A method as in claim 6, wherein

said selected times include times when said program applet is requested to present said further information.

8. A system, including:

a browser mechanism configured to present a web document from a web server to a web client, said web document including a first region associated with a set of further information;

an applet generation mechanism, at said web server, configured to generate a program applet in response to selection of said first region at the browser mechanism, said program applet being disposed to present said further information only upon selected conditions; and

a networking mechanism configured to transmit said program applet from said web server to said web client for execution by the browser mechanism.

9. A system as in claim 8, wherein said further information includes more detailed graphical information.

10. A system as in claim 8, wherein said further information includes access to a database.

11. A system as in claim 8, wherein said selected conditions include a selected number of times for presenting said further information, a selected period of time for presenting said further information, a requirement for presentation of selected authentication by said user, a requirement that the program applet is executing at a selected device or from a selected web document.

12. A system as in claim 8, wherein said selected conditions include a selected type of presentation of said further information.

13. A system as in claim 8, wherein

said program applet includes a unique ID;

said program applet attempts confirmation of said selected conditions with said web server at selected times; and

said program applet refuses to present said further information without said confirmation being successful.

14. A system as in claim 13, wherein

said selected times include times when said program applet is requested to present said further information.

15. A computer program product including:

a computer usable storage medium having computer readable code embodied therein for causing a computer generate a program applet, said computer readable code including;

computer readable program code configured to cause said computer to effect a browser mechanism configured to present a web document from a web server to a web client, said web document including a first region associated with a set of further information;

computer readable program code configured to cause said computer to effect an applet generation mechanism, at said web server, configured to generate said program applet in response to selection of said first region at the browser mechanism, said program applet being disposed to present said further information only upon selected conditions; and

computer readable program code configured to cause said computer to effect a networking mechanism configured to transmit said program applet from said web server to said web client for execution by the browser mechanism.

16. A computer program product as in claim 15, wherein said further information includes more detailed graphical information.

17. A computer program product as in claim 15, wherein said selected conditions include a selected number of times for presenting said further information, a selected period of time for presenting said further information, a requirement for presentation of selected authentication by said user, a requirement that the program applet is executing at a selected device or from a selected web document.

18. A computer program product as in claim 15, wherein said selected conditions include a selected type of presentation of said further information.

19. A computer program product as in claim 15, wherein

said program applet includes a unique ID;

said program applet attempts confirmation of said selected conditions with said web server at selected times; and

said program applet refuses to present said further information without said confirmation being successful.

20. A computer program product as in claim 19, wherein

said selected times include times when said program applet is requested to present said further information.
