Abstract: A system and method is provided for revoking a device. A method includes receiving a certificate from the device, the certificate including one or more of fields, at least one of the fields holding a signature, attempting to verify the signature, receiving a revocation list from a source, the revocation list identifying one or more data on the certificate as valid or invalid, the data including at least one of the fields of the certificate; and if one of one or more signatures identified unsuccessfully verified and one or more data is identified as invalid, preventing the transmission of a session key to the device, the session key being required to establish a secure communication channel.

Abstract: A system and method is provided for securing content stored on media. One method includes attaching content privileges to the media, wherein the privileges govern a plurality of levels of access, and configuring the media to permit access to the content according to the content privileges and predetermined conditions. An apparatus for securing content stored on media includes at least one tool for transferring content onto the media, the tool configured to attach a plurality of levels of access, wherein content privileges and predetermined conditions govern access to the content.

Abstract: A secure electronic content system and method is provided. The system includes a controller including an interface component, a host system coupled to the controller, the host system configured to present content under predetermined conditions, the host system operable with a navigation protocol, the host system further including a system manager operable with an associations component configured to be at least partially run by the host system, a translator configured to provide meanings and generate commands within the host system at least a first digital rights management (DRM) component configured to provide encoding and access rules for the content; and a file system component including a file system application programming interface (API) configured to provide a logical interface between a plurality of components.

Abstract: A system and method is provided for detecting unauthorized actions with respect to encrypted data on a media disk, the media disk including a first portion for prerecorded content and a second portion for written content. The method includes reading an identifier on the media disk, wherein the identifier includes one or more sections located in one of the first portion for pre-recorded content, the second portion for written content, and both the first portion for pre-recorded content and the second portion for written content, determining whether the identifier includes a section located in the second portion written content, comparing the identifier with one or more predetermined types of identifiers for which a section is located in the second portion for written content, and if the identifier is of a type that is one of the one or more predetermined types of identifiers, detecting an unauthorized action.

Abstract: Area-based resource collection comprises a system and method in which players in a real-time strategy game first define an area of influence, which, after the effects of other areas of influence have been considered, is used in calculating their resource collection potential.

Abstract: A buffer memory having addressable locations into which data blocks received from one of two or more devices are written and from which those data blocks are read to one of the other devices, is managed by a buffer memory controller. Selected, not necessarily sequential, buffer addresses are assigned by the controller to store data blocks included in a series supplied from the first device, and these assigned buffer addresses are loaded into register locations of a list register. Buffer addresses are read from an ordered list of the loaded register locations and respective data blocks are written into such addresses. Register locations from the ordered list are accessed to retrieve buffer addresses therefrom, and the data blocks stored in the retrieved buffer addresses are read from the buffer memory to the second device.
