Abstract: A method and apparatus is disclosed for increasing the security of computer networks through the use of an Intrusion and Misuse Deterrence System (IMDS) operating on the network. The IMDS is a system that creates a synthetic network complete with synthetic hosts and routers. It is comprised of a network server with associated application software that appears to be a legitimate portion of a real network to a network intruder. The IMDS consequently invites inquiry and entices the intruder away from the real network. Simulated services are configured to appear to be running on virtual clients with globally unique, class “C” IP addresses. Since there are no legitimate users of the virtual network simulated by the IMDS, all such activity must be inappropriate and can be treated as such. Consequently, the entire set of transactions by an intruder can be collected and identified rather than just those transactions that meet a predefined attack profile.

Abstract: An approach to computation of kernel descriptors is accelerated using precomputed tables. In one aspect, a fast algorithm for kernel descriptor computation that takes O(1) operations per pixel in each patch, based on pre-computed kernel values. This speeds up the kernel descriptor features under consideration, to levels that are comparable with D-SIFT and color SIFT, and two orders of magnitude faster than STIP and HoG3D. In some examples, kernel descriptors are applied to extract gradient, flow and texture based features for video analysis. In tests of the approach on a large database of internet videos used in the TRECVID MED 2011 evaluations, the flow based kernel descriptors are up to two orders of magnitude faster than STIP and HoG3D, and also produce significant performance improvements. Further, using features from multiple color planes produces small but consistent gains.

Abstract: Embodiments of the invention reduce the probability of success of a DOS attack on a node receiving packets by decreasing the probability of random collisions of packets sent by a malicious user with those sent by honest users. The probability of random collisions may be reduced in one class of embodiments of the invention by supplementing the identification field of the IP header of each transmitted packet with at least one bit from another field of the header. The probability of random collisions may be reduced in another class of embodiments of the invention by ensuring that packets sent from a transmitting IPsec node to a receiving IPsec node are not fragmented.

Abstract: Routing requests for data objects from clients includes receiving a request for a data object from a client, providing content servers capable of serving data objects, determining a server from the content servers, and informing the client of an address associated with the determined server accessible by the selected route. Determining a server includes, for each content server, identifying routes between the content server and the client, determining traversal times for the routes, and selecting a route from among the routes based on the traversal times.

Abstract: An approach to segmentation or clustering of a set of elements combines separate procedures and uses training data for those procedures on labeled data. This approach is applied to elements being components of an image of text (e.g., printed or handwritten). In some examples, the elements are connected sets of pixels. In images of text, the clusters can correspond to individual lines. The approach provides improved clustering performance as compared to any one of the procedures taken alone.

Abstract: An optical imaging system and method for performing random intensity illumination microscopy is disclosed. The system includes an incoherent signal light source, at least two diffusers having spatially random diffusion patterns, an image capture device that receives a reflected light signal from an object to be imaged, and a processor configured to perform digital image processing of the reflected signal. The method comprises acts of providing an incoherent light signal, diffusing the incoherent light signal with at least two diffusers having spatially random diffusion patterns to provide a diffused light signal, splitting the diffused light signal to provide a first light signal and a second light signal, reflecting the first light signal from a specimen to provide a reflected light signal, collecting the reflected light signal and the second light signal with an image capture device and processing the collected images to determine reflectance.

Abstract: Embodiments of a system and method for computer inspection of information objects, for example, executable software applications for common components that may include elements of computer viruses, items from hacker exploit libraries, or other malware components. Information objects may contain identified sequences of instructions, each of which may be identified and hierarchically grouped based on their structural relationship(s). In the software context, programming languages may include multiple components that include functional code; these components are often shared between programmers. In some embodiments, an inspection of the hierarchical relationship of components (e.g., constituent functions) in the information objects may allow for identification of common components shared between programs. In some embodiments, authorship of objects or components in the objects may be identified by comparisons between component samples.

Abstract: A system to detect subsurface activity. The system employs vibration sensor pairs, with each sensor pair having a shallow sensor and a deep sensor. Outputs of the sensors of a pair are processed together and events are detected based on the relative values detected by the sensors of the pair. When signal energy departs from a detected background level, the relative amplitude and frequency content of vibrations measured at the shallow and deep sensors may be compared. The comparison may be performed, at least in part, using a classifier that discriminates between subsurface activity and surface activity. The outputs of sensor pairs may be aggregated to make a determination of whether subsurface activity exists and/or its location. Aggregation may involve comparing the outputs of the same sensor pair at multiple time intervals or may involve comparing the outputs of arrayed sensor pairs.

Abstract: The systems and methods of the invention modulate atmospheric gases to temporarily increase the amount of atmospheric particles in the path of the debris, in order to decelerate the debris and accelerate natural orbital decay to the point of atmospheric re-entry. In one aspect of the invention, clearing the space debris includes propelling a plume of atmospheric gases substantially orthogonal to the path of the debris such that the debris collides with the gaseous plume as it passes through the plume. Increased atmospheric drag from the gaseous particles of the plume in the path of the debris obstructs a forward propagation of the debris and gradually decelerates the debris, leading eventually to atmospheric recapture.

Abstract: A method for text recognition includes generating a number of text hypotheses for an image, for example, using an HMM based approach using fixed-width analysis features. For each text hypothesis, one or more segmentations are generated and scored at the segmental level, for example, according to character or character group segments of the text hypothesis. In some embodiments, multiple alternative segmentations are considered for each text hypothesis. In some examples, scores determined in generating the text hypothesis and the segmental score are combined to select an overall text recognition of the image.

Abstract: A method for testing a speaker (212) and microphone (216) of a communication device (110) is provided. The method includes playing a first audio signal through the speaker (212) and determining whether the first audio signal is audible. If the first audio signal is audible, the communication device (110) receives a second audio signal through its microphone (216) and plays the second audio signal through the speaker (212). If the second audio signal is audible the method determines that the microphone (216) is properly functioning. Such a method allows the communication device (110) to be quickly and easily tested.

Abstract: Embodiments of an inspection system and method for a collection of information objects, for example, a collection of executable software applications may be inspected for computer viruses, or a collection of genomes may be inspected for common or unique gene sequences. Information objects may contain identified sequences of instructions, each of which may be labeled with a symbol. In the software context, programming languages may include symbols that indicate functionality. In some embodiments, an inspection of the statistical properties of the information objects and their included symbols may allow for the symbols (and thus instruction sequences) to be grouped into logical components. In some embodiments, objects that include individual logical components may be grouped together. These groupings and their dependencies may be used to determine the structure of each object by detailing its constituent components, how they relate or depend on one another, and how the information object may function.

Abstract: A method, apparatus and computer program product for non-uniform per-packet priority marking for use with adaptive protocols is presented. A packet is received at a first network device, the packet assigned to a priority band. A priority is determined for the packet between a lowest priority of the priority band and a highest priority of the priority band, the priority for the packet selected based on a target distribution of priorities within the priority band, the target distribution comprising a distribution selected to achieve a desired capacity relationship among groups of packets assigned to different priority bands. The selected priority is assigned to the packet.

Abstract: The disclosed systems and methods provide for the compression and decompression of packet headers. An uncompressed header can be compressed in size to form a smaller, compressed header, such that the compressed header can include values that can be used to re-produce the uncompressed header. A compressed header can include at least two such values. A first value of the at least two values can be computed based on a second, earlier uncompressed header and can be used to derive the uncompressed header. Similarly, a second value of the at least two values can be computed based on a third uncompressed header and can be used to derive the same uncompressed header. Accordingly, the uncompressed header can be derived based on the first value and the second uncompressed header, or based on the second value and the third uncompressed header. The uncompressed header, second uncompressed header, and third uncompressed header can be associated with different packets.
