Abstract: A method of assessing and addressing computer security risk is disclosed.

Abstract: A method and apparatus for extracting and displaying a feature data set is provided.

Abstract: An improved web crawler, associated method of crawling the Internet, and automatically detection of crawled webpage changes are provided. The method comprises obtaining a first version and a second version of the webpage; generating a first simhash of the first version of the webpage and a second simhash of the second version of the webpage; calculating, using a similarity hashing function having small output perturbations for small input perturbations, a probability that there are no differences between the first version of the webpage and the second version of the webpage; providing, to one or more researcher computers, the first version of the webpage and the second version of the webpage; based on input identifying a change in the webpage, updating a count of changes associated with the webpage; providing information about the change in the webpage in the second version of the webpage relative to the first version of the webpage as feedback to the crawler.

Abstract: Disclosed herein are systems, methods, and machine readable media that enable object localization with an RFID infrastructure. Localization is performed by modeling the distance-decaying behavior of received signal strength. Selection of optimally performing tag types and the use of uniformly sensitive tags of those optimal tag types further enhances localization accuracy. When these components are combined, RFID becomes a feasible way to locate moving and stationary objects in a 3D environment that includes other objects, as well as noise and signal pollution.

Abstract: A vulnerability report evaluation system comprises a preprocessor that takes as its input a data record representing a vulnerability report and outputs a search record. The vulnerability report evaluation system further comprises a search engine and a searchable corpus comprising records of vulnerabilities, wherein the search engine is configured to use the outputted search record to search the corpus. The vulnerability report evaluation system can flag search result hits resulting from the searched search record as an indication that the submitted vulnerability report is a duplicate of an earlier vulnerability report or as a flag to trigger manual review, while providing efficient processing of vulnerability report data records.

Abstract: Object localization with an radio-frequency identification (RFID) infrastructure is described. A plurality of transmission power levels established by an RFID reader can be searched to determine a measurement power level corresponding to a target. A region that includes the target can then be determined using information about a physical relationship between the RFID reader and a reference location via correlating the measurement power level to a reference power level corresponding to the reference location.

Abstract: A method for tracking one or more portable devices in real time to detect theft of the one or more portable devices is provided. The method enables, firstly, interrogating a Radio Frequency Identification (RFID) tag via a RFID reader during successive sweep intervals. The sweep interval represents active state of the RFID reader. Secondly, the method enables receiving one or more pairing information from the RFID tag. Further, the method enables comparing the one or more pairing information with corresponding one or more pairing information stored in the RFID reader. Finally, the method enables generating an alert signal via the wearable-band or the one or more portable devices when the one or more pairing information does not match with the corresponding one or more pairing information stored in the RFID reader.
