Malware detection using file names
Descriptions of files detected at endpoints are submitted to a security server. The descriptions describe the names of the files and unique identifiers of the files. The security server uses the unique identifiers to identify files having different names at different endpoints. For a given file having multiple names, the names are processed to account for name differences unlikely to have been caused by malware. The processed names for the file are analyzed to determine the amount of dissimilarity among the names. This analysis is used to generate a score indicating a confidence that the computer file contains malicious software, where a greater amount of dissimilarity among the names generally indicates a greater confidence that the computer file contains malicious software. The score is weighted based on file name frequency, the age of the file, and the prevalence of the file.

Average-complexity ideal-security order-preserving encryption
Embodiments provide ideal security, order-preserving encryption (OPE) of data of average complexity, thereby allowing processing of the encrypted data (e.g. at a database server in response to received queries). Particular embodiments achieve high encryption efficiency by processing plaintext in the order preserved by an existing compression dictionary already available to a database. Encryption is based upon use of a binary search tree of n nodes, to construct an order-preserving encryption scheme having Ω(n) complexity and even O(n), in the average case. A probability of computationally intensive updating (which renders conventional OPE impractical for ideal security) is substantially reduced by leveraging the demonstrated tendency of a height of the binary search tree to be tightly centered around O(log n). An embodiment utilizing such an encryption scheme is described in the context of a column-store, in-memory database architecture comprising n elements. OPE according to embodiments is compatible with adjustable encryption approaches. |

Unsupervised analytical review
Disclosed is a method generally applicable to any financial dataset for the purposes of: (1) determining the most important patterns in the given dataset, in order of importance; (2) determining any trends in those patterns; (3) determining relationships between patterns and trends; and (4) allowing quick visual identification of anomalies for closer audit investigation. These purposes generally fall within the scope of what in financial auditing is known as ‘analytical review’. The current method's advantages over existing methods are that is fully independent of the financial data subject to analysis, requires no background knowledge of the target business or industry, and is both scalable (to large datasets) and fully scale-invariant, requiring no a priori notion of financial materiality. These advantages mean, for example, that the same method can be by an external auditor for many different clients with virtually no client-specific customization, directing his attention to the areas where more detailed audit investigation may be required. Compared with existing methods, the current method is extremely flexible, and because it requires no a priori knowledge, saves significant time in understanding the fundamentals of a business. |

Efficient coding of overcomplete representations of audio using the modulated complex lapped transform (MCLT)
An “Overcomplete Audio Coder” provides various techniques for overcomplete encoding audio signals using an MCLT-based predictive coder. Specifically, the Overcomplete Audio Coder uses unrestricted polar quantization of MCLT magnitude and phase coefficients. Further, quantized magnitude and phase coefficients are predicted based on properties of the audio signal and corresponding MCLT coefficients to reduce the bit rate overhead in encoding the audio signal. This prediction allows the Overcomplete Audio Coder to provide improved continuity of the magnitude of spectral components across encoded signal blocks, thereby reducing warbling artifacts. Coding rates achieved using these prediction techniques are comparable to that of encoding an orthogonal representation of an audio signal, such as with modulated lapped transform (MLT)-based coders. Finally, the Overcomplete Audio Coder provides a true magnitude-phase frequency-domain representation of the audio signal, thus allowing precise auditory models to be applied for improving compression performance, without the need for additional Fourier transforms. |

High-quality passive performance capture using anchor frames
High-quality passive performance capture using anchor frames derives in part from a robust tracking algorithm. Tracking is performed in image space and uses an integrated result to propagate a single reference mesh to performances represented in the image space. Image-space tracking is computed for each camera in multi-camera setups. Thus, multiple hypotheses can be propagated forward in time. If one flow computation develops inaccuracies, the others can compensate. This yields results superior to mesh-based tracking techniques because image data typically contains much more detail, facilitating more accurate tracking. Moreover, the problem of error propagation due to inaccurate tracking in image space can be dealt with in the same domain in which it occurs. Therefore, there is less complication of distortion due to parameterization, a technique used frequently in mesh processing algorithms. |

Method and apparatus for image encoding using hold-MBs, and method and apparatus for image decoding using hold-MBs
In video/image coding, macroblocks (MBs) are often intra coded in raster scan order, starting from one seed MB. The invention improves intra prediction for optimized usage of multi-core processors. Encoding starts from multiple intra coded seed MBs per frame, and continues with adjacent MBs. A predefined prediction spread pattern (growth pattern) is used that comprises simultaneous prediction of two or more adjacent MBs per MB. Adjacent MBs with high coding cost are called “Hold-MB” and can be held from being processed, until another neighboring edge is available for prediction. Encoding comprises marking a MB with high coding cost for deferred prediction. This MB is skipped while the other MBs are encoded. When a further adjacent MB was encoded, the marked MB is predicted based on the adjacent MBs. Since a decoder receives the deferment marks and uses the same growth pattern, it follows the encoder, and predicts and decodes correctly. |

Provided are a base station, a mobile station, a method for transmitting calculation parameters for a power headroom and a method for transmitting a power headroom capable of increasing the accuracy of link adaptation by reducing the probability that a power headroom value is out of a reported range. In a base station (100), a PHR bandwidth notifier (105) determines a bandwidth for power headroom calculation to be used for calculating a power headroom by a mobile station (200) for a component carrier to which an unlink allocation signal (UL grant) is not mapped and generates a notification signal containing information on the determined bandwidth for power headroom calculation, and a transmitting means (modulator (106), transmission RF unit (107)) transmits the generated notification signal to the mobile station (200). Specifically, the PHR bandwidth notifier (105) determines a bandwidth for PHR calculation according to an estimated path-loss level. |

Multi-carrier modulation with hierarchical resource allocation
Methods and systems for communicating in a multi-carrier communication system are disclosed. Radio resources may be organized in at least three hierarchical levels. The hierarchical levels may comprise macroblocks, blocks, and radio resource elements. A macroblock may contain a plurality of blocks and a block may contain a plurality of radio resource elements. The radio resource elements may further correspond to subcarriers in an orthogonal frequency division multiplexing (OFDM) symbol. An index in a control message may specify a modulation and/or coding scheme (MCS) pattern indicting a MCS for each block within a macroblock. In an embodiment, fewer bits are used by the index to specify a MCS pattern that is used statistically more frequently, and more bits are used by the index to specify a MCS pattern that is used statistically less frequently. Signals may be transmitted over the plurality of macroblocks. |
