  • Publication number: 20140201541
    Abstract: The data vaporizer provides secure online distributed data storage services that securely store and retrieve data in a public distributed storage substrate such as public cloud. The data vaporizer vaporizes (e.g., fragmented into tiny chunks of configurable sizes) data and distributes the fragments to multiple storage nodes so that the data is not vulnerable to local disk failures, secures data so that even if some of the storage nodes are compromised, the data is undecipherable to the attacker, stores data across multiple cloud storage providers and/or parties using keys (e.g., tokens) provided by multiple parties (including the owners of the data) and maintains data confidentiality and integrity even where one or more data storage provider is compromised. The data vaporizer is configurable for different domain requirements including data privacy and anonymization requirements, encryption mechanisms, regulatory compliance of storage locations, and backup and recovery constraints.

  • Patent number: 8659865
    Abstract: An electrical circuit for protecting an electrical load from overload current is provided. The system includes a voltage transformer configured to receive AC mains voltage from an electric mains supply and further configured to apply reduced voltage to the electrical load. A control switch comprising metal contacts is connected to the voltage transformer. The control switch is configured to facilitate application of reduced value of AC mains voltage to the electrical load. A reduced value of current flowing through the electrical load is measured by a current transformer connected in series with the electrical load. The reduced value of current is then used for estimating a current consumption value in event of AC mains voltage being directly applied to the electrical load. A control signal is then used for disconnecting the electrical circuit if the estimated current consumption value is greater than threshold overload current value.

  • Publication number: 20140026123
    Abstract: Systems and methods for replication of test results in a network environment are disclosed. Methods described may include recording network traffic in a first instance of a test case by a network emulator node emplaced in the network environment, recording a time at which a connection open at the network emulator node completes a communication task, and deriving an order of task completion for each extant open connection thereby, and detecting the occurrence of one or more events, such as a packet drop, a packet retransmission, or a packet delay, among other events. Replication, as described, additionally involves recording the nature of the event and identification information associated with the packet to which the event is detected to have occurred; and associating the one or more events with each of the packets recorded, on the basis of the identification information and event recording.

  • Patent number: 8597124
    Abstract: The Fair-Ordering Service delivers action messages to the server as soon as it is feasible. Because action messages from different players exhibit different reaction times with respect to an update message, the Fair-Ordering Service executed at the server dynamically enforces a sufficient waiting period on each action message to guarantee the fair processing of all action messages. The Fair-Ordering Service takes into consideration delayed and out-of-order action messages. When action messages corresponding to multiple update messages are interleaved, the Fair-Ordering Service matches the action message to the appropriate update message by maintaining a window of update messages and using the reaction times for an action message for each of the update messages in the window. This enables state changes at the game server to be performed with fairness to all the players. The Fair-Ordering Service is based on a framework that uses a proxy architecture.

  • Publication number: 20130266193
    Abstract: Biometric matching technology, in which a watch list is managed, multiple images of a potential suspect are accessed, and parallel pre-processing of the multiple images is controlled. Based on the pre-processing, an image of the potential suspect to use in matching against the watch list is determined and the determined image is used to search sorted biometric data included in the watch list. A subset of persons from the watch list is identified based on the search and parallel analysis of the determined image of the potential suspect against detailed biometric data associated with the subset of persons in the watch list is controlled. Based on the parallel analysis, it is determined whether the potential suspect matches a person in the watch list and a result is outputted based on the determination.
