| 20090003660 | OBJECT IDENTIFICATION AND VERIFICATION USING TRANSFORM VECTOR QUANTIZATION - An identification system uses mappings of known objects to codebooks representing those objects to identify an object represented by multiple input representations or to verify that an input representation corresponds to an input known object. To identify the object, the identification system generates an input feature vector for each input representation. The identification system then accumulates for each known object the distances between the codebook of that object and each of the input feature vectors. The distance between a codebook and a feature vector may be the minimum of the distances between the code vectors of the codebook and the feature vector. The identification system then selects the object with the smallest accumulated distance as being the object represented by the multiple input representations. | 01-01-2009 |

A classifier inputs a voice sample of an person and tries to authenticate or identify the person. A classifier generates a sequence of feature vectors for the input voice sample and then a code vector for that sequence. The classifier uses its codebook store to recognize the person. The speaker recognition system then combines the scores of the classifiers to generate an overall score. If the score satisfies a recognition criterion, then the speaker recognition system indicates that the voice sample is from that speaker. | 01-01-2009 |

Low order coefficients may be discarded depending on level accuracy desired. DFT coefficients and color data for the primary and secondary colors may then be used to construct an abstraction of the original image data, using data that is, in some cases, three or four orders of magnitude smaller than the original image data. | 12-10-2009 |

| 20110107418 | DETECTING ANOMALIES IN ACCESS CONTROL LISTS - An access control anomaly detection system and method to detect potential anomalies in access control permissions and report those potential anomalies in real time to an administrator for possible action. Embodiments of the system and method input access control lists and semantic groups (or any dataset having binary matrices) to perform automated anomaly detection. This input is processed in three broad phases. First, policy statements are extracted from the access control lists. Next, object-level anomaly detection is performed using thresholds by categorizing outliers in the policies discovered in the first phase as potential anomalies. This object-level anomaly detection can yield object-level security anomalies and object-level accessibility anomalies. Group-level anomaly detection is performed in the third phase by using semantic groups and user sets extracted in first phase to find maximal overlaps using group mapping. This group-level anomaly detection can yield group-level security anomalies and group-level accessibility anomalies. | 05-05-2011 |

The first partition is brought offline, and the software on each of its nodes is updated. The nodes are partially initialized and form an offline cluster, leaving uninitialized subsystems that share external resources or external communication. The second partition is brought offline. The nodes of the first partition complete their initialization and the first partition cluster is brought online. The nodes of the second partition are updated and join the first partition cluster. Quorum mechanisms are adjusted to allow each partition to operate as a cluster. The system thereby updates each node of the cluster with minimal time offline and without requiring software of different versions to intercommunicate. | 06-04-2009 |
