Abstract: A digital rights management system includes two digital rights management servers (RMS servers) connected to a client computer. The two RMS servers implement different but related digital rights management (DRM) policies, with the first RMS server implementing conventional DRM policies and the second RMS server implementing extended DRM policies. An application program on the client computer interacts with a document on the client computer, and communicates with the first RMS server to obtain access authorization for the document. A plug-in program in the client computer cooperates with the application program, and communicates with the second RMS server to obtain additional access authorization for the document. Access to the document is granted when both RMS servers grant access to the document. This achieves extended digital rights management control which can provide a more flexible access control than that provided by existing DRM systems.

Abstract: Methods for managing contents of multiple digital documents for individual users, to generate aggregated documents from multiple documents and/or create associations among multiple documents, based on the user's interactions with multiple digital documents. A document content aggregation method can, on a personalized basis, aggregate contents from multiple digital documents into an aggregated document based on a user's past interactions with the documents. The aggregation is based on a content importance score calculated from the user interaction pattern. A document association method can, on a personalized basis, create associations among multiple digital documents based on the user's past interactions with the documents. Two documents are deemed related if there is a user interaction pattern where the user interacts with both documents with a predetermined time interval from each other. When displaying one document, link icons are displayed to allow the user to directly navigate to the related documents.

Abstract: In a digital rights management system, a rights management server sends event notifications to certain users when other users perform certain actions (read, print, copy, etc.) on documents managed by the system. For each document, a notification rule defines which users will receive what event notifications for that document. The notification rule is determined based on document access permissions possessed by the users, so that only users who have permission to perform an action on the document will receive notifications when other users perform that action on the document, while users with no permission to perform an action will not receive notifications when other users perform that action. The server also allows the users who have permission to perform an action to opt out of the notifications. The server monitors events that occur on the documents, and sends event notifications to appropriate users according to the notification rules.

Abstract: A method implemented in a system including a copier or scanner connected to a digital rights management (DRM) server, which can prevent unauthorized copy or scan while allowing authorized users to obtain high quality hardcopies or scans. After the copier or scanner scans an input hardcopy document, the server determines whether the scanned document image matches any protected document in the DRM system. If a match is found, and the server determines that the user is permitted to copy or distribute the document, the server transmits an electronic version of the matched document from the DRM system to the copier or user-selected email recipients, so that the user or the email recipients can receive a high quality document. If a matched document is found but the user is not permitted to copy or distribute it, the copier or scanner deletes the scanned document image without printing or saving it.

Abstract: A method for automatically applying digital rights management (DRM) to outgoing emails based on a color category of the email set by the sending user. A plugin module on the user's computer interacts with the email application to extract the color category setting for the email and converts it to a category ID recognized by the digital rights management (RMS) server. The RMS server determines the DRM policy corresponding to the category ID using an association table, and applies that DRM policy to protect the email before sending the email to an exchange server. When a recipient receives the email, the application program on the recipient's computer cooperates with the RMS server to determine whether the recipient is allowed to access the email based on the DRM policy that has been applied to the email.

Abstract: In a digital rights management system, layers are defined for each document and user permissions are specified for each layer, to control user access at the layer-level. The layers are ordered by depth, where a layer completely contained inside another layer is deemed deeper than the other layer. The layers are encrypted in a deep-to-shallow order, each by its own encryption key. The entire document is then encrypted. When a user requests access to a document, the system generates an ordered sequence of encryption keys based on the user's access rights for each layer. The document open program on the user's client computer attempts to decrypt the various layers using the ordered sequence of keys. The client program and the system's key sequence generating algorithm are designed to give the result that only layers that the user has access to are successfully decrypted and displayed at document open time.

Abstract: A server in a digital rights management system implements version control for the digital documents being managed. Each document belongs to a document series and has a version number. The server maintains a version control database table that stores, for each document, the document series name and version number, and parameters indicating whether the document is obsoleted or deleted. When registering a new document, based on auto-obsolete and auto-delete parameters inputted by the user, the server automatically obsoletes or deletes certain older version documents that belong to the same series as the new document. The server controls access to the documents so that obsoleted documents will not be accessible to users even if they still have local copies of such documents. When a user requests access to an older version document that is not obsoleted, the server may allow access to the latest version document instead.

Abstract: A hybrid digital rights management (DRM) system includes a hybrid digital rights management server (RMS server) connected to first and second RMS servers and a client computer. The hybrid RMS server stores a policy mapping table that maps its DRM policies to remote DRM policies on the first or second RMS servers, and can also create policies that satisfy the schema requirements of the first or second RMS server using policies stored in the hybrid RMS server. When the hybrid RMS server receives a document protection request from the client computer, it extracts the filename extension for the document to be protected, and uses the filename extension to select one of the first and second RMS servers as a target RMS server. The document is protected by the target RMS server, and also added to a protected document database on the hybrid RMS server.

Abstract: A digital rights management (DRM) method for protecting digital documents, implemented in a DRM system. When an operator (document publisher) scans a document on a scanner to generates a digital document and specifies a list of users who will be granted access rights to the document, the DRM system applies digital rights protection to the document according to the specified access rights, and distributes the document to the specified users; the system also sends a confirmation notification such as an email to the document publisher, which contains a list of the receiving users, a copy of the protected digital document, and a link to a web-based tool that will allow the publisher to modify the access rights granted to the users. In addition, when applying digital rights protection, the DRM system specifies the publisher as a user who will have access rights 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.
