Abstract:
The invention provides a method and system for presenting information 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.
