Abstract:
A method for dynamic display of at least one layer in a PDF document, comprising the steps of setting at least one criterion for at least one property of a trigger to change a display state of the at least one layer of the PDF document to another display state of the at least one layer of the PDF document, creating a script that can be processed by a PDF document reader and that contains the at least one criterion for the at least one property of the trigger, and embedding the script in the PDF document, wherein when the PDF document is opened by the PDF document reader, the script causes evaluation of the at least one property for the trigger, and if the at least one criterion for the at least one property of the trigger is met, then the script causes a change of the display state of the at least one layer of the PDF document.
Abstract:
A user interface display method implemented on a computer-controlled device to allow an operator to define a list of selected items among a plurality of items available for selection. The operator starts by selecting a pre-existing list containing a number of selected items. A modified list is generated which initially contains the same items as the pre-existing list. The device displays all of the items available for selection, as well as first and second indications associated with each item initially in the modified list. Then, in response to operator inputs to add items to (or remove items from) the modified list, second indications are displayed (or removed from display) in association with the items to be added (or removed), without changing the display of any of the first indications and any of the plurality of items. The modified list is saved without changing the pre-existing list.
Abstract:
A method for automating the management and interpretation of digital documents and their rights metadata to generate user access of a document protected by digital rights management (DRM), comprising the steps of a server obtaining a digital document and its associated rights metadata, the server interpreting the metadata to ascertain DRM useful information including identifications (IDs) of the document and its users and associated digital rights, and the server generating entries for a DRM database including policies associated with the document ID and users IDs based on the ascertained DRM useful information to enable DRM protection to the document.

Abstract:
In a digital rights management (DRM) system having a server and a client, a method can dynamically enforce users' access rights to protected documents even after a document is already open in a viewer application on the client. The server has a DRM database storing various access rights of users with respect to documents, and grants access permissions upon request from the client to allow specific users to access specific documents. In addition to requesting access permissions at the time of opening a document, the client requests updated permissions from the server from time to time while the document is still open. If the updated permissions are different from those granted at the time the document was opened, the client dynamically disables/enables or modifies the functions of the viewer application based on the updated permissions while the document is still open.

Abstract:
A method for managing rights management policies for user access and use of digital documents with nontraditional rights control in addition to traditional rights management services (RMS) based on digital rights management (DRM) policies assigned to respective digital documents and their users and stored in an RMS database, including the steps of: a server, upon receiving a user's request regarding a document protected by one or more DRM policies, determining whether the document has additional nontraditional rights control for the user; the server checking a nontraditional policy service (NPS) database, and validating the user's information with one or more NPS database entries of NPS policy extensions pertaining to the document and the user, where the NPS policy extensions amend the DRM policies with additional nontraditional rights control; and the server denying the user's request if the user's information cannot be validated by anyone of said one or more NPS database entries of the NPS policy extensions pertaining to the document and the user, or granting the user's request if the user's information can be validated by all of said one or more NPS database entries of the NPS policy extensions pertaining to the document and the user.
