    摘要: A method of securely providing data to a user's system over a broadcast infrastructure. The method comprising the steps of: encrypting the data using a first encrypting key; encrypting a first decrypting key using a second encrypting key; dividing at least part of the encrypted data into a series of logical packages; placing at least some of the logical packages into a broadcast carousel for cyclical broadcast over the broadcast infrastructure; broadcasting the packages in broadcast carousel so that they can be received by at least one user's system, wherein the broadcast is cyclical and repeats periodically; and transferring the encrypted first decrypting key, which has been encrypted with the second encrypting key, to the user's system. In another embodiment, a system is disclosed to carry out the above method in a broadcast infrastructure and an image overlaid on top of a primary image being displayed isused to denote that additional logical packages are available for receipt by broadcast.

    摘要: A digital rights management (DRM) system and methodology for a Java client implementing a Java Runtime Environment (JRE). The JRE comprises a Java Virtual Machine (JVM) and Java runtime libraries components and is capable of executing a player application for presenting content that can be presented through a Java program (e.g., a Java application, applet, servlet, bean, etc.) and downloaded from a content server to the client. The DRM system includes an acquisition component for receiving downloaded protected contents; and a dynamic rights management layer located between the JRE and player application for receiving requests to view or play downloaded protected contents from the player, and, in response to each request, determining the rights associated with protected content and enabling viewing or playing of the protected contents via the player application if permitted according to the rights. By providing a DRM-enabled Java runtime, which does not affect the way non-DRM-related programs work, DRM content providers will not require the installation of customized players. By securing the runtime, every Java™ player automatically and transparently becomes a DRM-enabled player.

    摘要: A method, a system and computer readable medium of securely receiving data on a user's system from a web broadcast infrastructure with a plurality of channels. The method includes encrypting the data using a first encrypting key, wherein the first encrypting key is self-contained with all the information necessary to decrypt the data encrypted with the first encrypting key and encrypting the first decrypting key, using a second encrypting key. Next promotional metadata related to at least part of the encrypted data on a first web broadcast channel for reception by at least one user's system is broadcasted. Broadcasting at least part of the encrypted data over a second broadcast channel and transferring the encrypted first decrypting key, which has been encrypted with the second encrypting key, to the user's system via a computer readable medium.

    摘要: A digital rights management system for controlling the distribution of digital content to player applications. The system comprises a verification system, a trusted content handler, and a user interface control. The verification system is provided to validate the integrity of the player applications; and the trusted content handler is used to decrypt content and to transmit the decrypted content to the player applications, and to enforce usage rights associated with the content. The user interface control module is provided to ensure that users of the player applications are not exposed to actions that violate the usage rights. The preferred embodiment of the present invention provides a system that enables existing content viewers, such as Web browsers, document viewers, and Java Virtual Machines running content-viewing applications, with digital rights management capabilities, in a manner that is transparent to the viewer. Extending content viewers with such capabilities enables and facilitates the free exchange of digital content over open networks, such as the Internet, while protecting the rights of content owners, authors, and distributors. This protection is achieved by controlling access to the content and constraining it according to the rights and privileges granted to the user during the content acquisition phase.
