  • Patent number: 9032521
    Abstract: Performing adaptive cyber-security analytics including a computer implemented method that includes receiving a report on a network activity. A score responsive to the network activity and to a scoring model is computed at a computer. The score indicates a likelihood of a security violation. The score is validated and the scoring model is automatically updated responsive to results of the validating. The network activity is reported as suspicious in response to the score being within a threshold of a security violation value.

  • Patent number: 8856313
    Abstract: A system and method for determining data usage based on provenance information, in a stream-processing system, includes progressively setting usage information for output stream data objects (SDOs), determining input SDOs that an output SDO depends on, based on a provenance dependency function; recursively feeding back the usage information for a subset of SDOs that can be discarded; and discarding the subset of SDOs. A system and method for data retention based on usage information, in a stream-processing system, includes managing retention of SDOs by deleting SDOs that are determined to be of null usage; and enhancing retention characteristics of SDOs that are deemed to have usage.

  • Patent number: 8233494
    Abstract: A technique for analyzing two or more data streams respectively generated from two or more components of a controllable process includes the following steps. In a first step, a statistical analysis is performed on each of the two or more data streams to generate first analysis results in the form of respective statistical results for the two or more data streams. In a second step, at least a portion of the statistical results from at least one of the two or more data streams is combined with at least a portion of the statistical results from at least another one of the two or more data streams to yield second analysis results. The controllable process is adjustable based on at least one of the first analysis results and the second analysis results.

  • Patent number: 8112541
    Abstract: A system and method for dynamically building applications for stream processing includes providing processing elements with a flow specification describing each input and a stream description describing each output such that the flow specification indicates a stream or streams which are to be received based on processing information and the stream descriptions indicate the processing information. Processing elements that can be reused are identified by determining equivalence between the processing elements. Processing elements that are new and are not reusable are instantiated in a flow graph. An application is dynamically composed, using the instantiated processing elements by routing available streams to the instantiated processing elements in accordance with the flow specifications.

  • Patent number: 7657651
    Abstract: A resource-efficient live streaming system includes a broadcaster and a streaming server. The broadcaster receives a live feed and broadcasts a media stream to the streaming server containing several descriptions of the live feed along with control information. The broadcaster includes a stream thinner that implements a pruning algorithm. If descriptions from different streams are similar enough, one or more of them may be discarded without penalizing the quality of service perceived by the receivers. The streaming server assembles compressed data units into streams according to the control information from the broadcaster. The streaming server may also gather client feedback in order to estimate the status of the transmission channels and forwards the information to the broadcaster. The streaming server builds and streams media information to clients according to user preferences and receiver capabilities.
