Abstract: A system for providing persistent access control of protected content is disclosed. The method on a client system includes sending a first request for authentication of the client to a server system. Subsequently, the client is authenticated by the server. Next, a user on the client attempts to access a file comprising a trailer and content encrypted with an encrypting key. Then, a second request for access to the content is sent to the server by the client, wherein an identifier from the trailer is included in the second request. The identifier identifies the content or an access control policy of the content. The server determines that the second request is in accordance with an access control policy associated with the content, and grants access to the content. Lastly, the client accesses the content in accordance with the access control policy.

Abstract: A method, system and computer program product for pushing contents to client devices is disclosed. The method, system, and computer program product handles group pushes, manages different content priorities, prevents one content push from starving others, and handles different transport mechanisms for different clients.

Abstract: 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.

Abstract: A method of securely receiving data on a user's system from a web broadcast infrastructure with a plurality of channels. The method comprising receiving promotional metadata from a first web broadcast channel, the promotional metadata related to data available for reception; assembling at least part of the promotional metadata into a promotional offering for review by a user; selecting by a user, data to be received related to the promotional metadata; receiving data from a second web broadcast channel, the data selected from the promotional metadata, and wherein the data has been previously encrypted using a first encrypting key; and receiving the first decrypting key via a computer readable medium, the first decrypting key for decrypting at least some of the data received via the second web broadcast channel. In another embodiment, a method and system to transmit data securely from a web broadcast center is disclosed.

Abstract: 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.

Abstract: 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.

Abstract: 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.
