Abstract: A cryptographic authentication system comprises an authentication media key block that comprises media key precursors. The system generates transformed keys by applying a function to a media ID of a media and each of the media key precursors, and generates entries in a binding table by applying an encrypting function to a media key of an encrypted content and each of the transformed keys. To play encrypted content, a media player processes the authentication media key block using a device key to extract a media key precursor, extracts a media key from the binding table using the extracted media key precursor and the media ID, and verifies that the extracted media key matches the media key of the encrypted content, allowing the media device to decrypt and play the encrypted content.

Abstract: A method of incrementally maintaining a stable, bounded, uniform random sample S from a dataset R, in the presence of arbitrary insertions and deletions to the dataset R, and without accesses to the dataset R, comprises a random pairing method in which deletions are uncompensated until compensated by a subsequent insertion (randomly paired to the deletion) by including the insertion's item into S if and only if the uncompensated deletion's item was removed from S (i.e., was in S so that it could be removed). A method for resizing a sample to a new uniform sample of increased size while maintaining a bound on the sample size and balancing cost between dataset accesses and transactions to the dataset is also disclosed. A method for maintaining uniform, bounded samples for a dataset in the presence of growth in size of the dataset is additionally disclosed.

Abstract: A content addressable memory array storing stored words in memory elements. Each memory element stores one of at least two complementary binary bits as one of at least two complementary resistances. Each memory element is electrically coupled to an access device. An aspect of the content addressable memory array is the use of a biasing circuit to bias the access devices during a search operation. During the search operation, a search word containing a bit string is received. Each access device is biased to a complementary resistance value of a corresponding search bit in the search word. A match between the search word and stored word is indicated if the bits stored in the memory elements are complementary to the bits represented by the resistances in the access devices.

Abstract: A virtual binding system ensures that the WORM logic for protecting data immutability cannot be circumvented, effectively guaranteeing WORM property of a WORM storage system composed of rewritable magnetic hard disks. To close the security hole between the rewritable media and the WORM logic, virtual binding securely authenticates the legitimacy of a WORM logic controller before granting data access on a WORM storage media. Furthermore, the system verifies the legitimacy of the WORM logic controller during data access. This approach virtually binds together the WORM logic controller and the WORM storage media even though the WORM logic controller and the WORM storage media may be physically separate.

Abstract: An information handling system includes instruction processing nodes in respective physical partitions. A communications bus couples two information processing nodes together. Each node includes hardware resources such as CPUs, memories and I/O adapters. Prior to a command to merge the physical partitions, the communication bus exhibits a disabled state such that the two information processing nodes are effectively disconnected. After receiving a command to merge the physical partitions, the system enables the communication bus to effectively hot-plug the two nodes together. A modified master hypervisor in one node stores data structures detailing the hardware resources of the two nodes. The modified master may assign resources from one node to a logical partition in another node.

Abstract: A method for responding to inquiries from a user by a response support system. A request displaying a second screen is received from a user terminal of the user in which a first screen is being displayed. An inquiry destination of the response support system is identified in the first screen. Screen data pertaining to the second screen and containing an operation object is retrieved. The second screen is configured to be sent to the inquiry destination in response to an operation performed on the operation object by the user. Screen transition information containing screen identifiers of screens previously displayed by the user terminal, including the first screen, is retrieved. The second screen is assembled by inserting the retrieved screen data and the retrieved screen transition information into the second screen. The assembled second screen is sent to the user terminal.

Abstract: An optoelectronic circuit fabrication method and integrated circuit apparatus fabricated therewith. Integrated circuits are fabricated with an integral optical coupling transition to efficiently couple optical energy from an optical fiber to an integrated optical waveguide on the integrated circuit. Layers of specific materials are deposited onto a semiconductor circuit to support etching of a trench to receive an optical coupler that performs proper impedance matching between an optical fiber and an on-circuit optical waveguide that extends part way into the transition channel. A silicon based dielectric that includes at least a portion with a refractive index substantially equal to a section of the optical fiber is deposited into the etched trench to create the optical coupler. Silicon based dielectrics with graded indices are also able to be used. Chemical mechanical polishing is used finalize preparation of the optical transition and integrated circuit.

Abstract: A method of data loading for large information warehouses includes performing checkpointing concurrently with data loading into an information warehouse, the checkpointing ensuring consistency among multiple tables; and recovering from a failure in the data loading using the checkpointing. A method is also disclosed for performing versioning concurrently with data loading into an information warehouse. The versioning method enables processing undo and redo operations of the data loading between a later version and a previous version. Data load failure recovery is performed without starting a data load from the beginning but rather from a latest checkpoint for data loading at an information warehouse level using a checkpoint process characterized by a state transition diagram having a multiplicity of states; and tracking state transitions among the states using a system state table.

Abstract: A date querying system processes free-form text in documents to identify and locate some or all of the dates in the documents using extended regular expression matching to capture various date formats. The system packages a canonicalized format of each identified date to support various types of queries such as, for example, specific date querying, hierarchical date querying, range date querying, proximity queries comprising a date and any keywords, and any combination of types of queries. The system scans a document to identify the various format dates occurring in the document, disambiguates the resulting occurrences of dates, and canonicalizes the dates according to one or more predetermined formats.
