Abstract: Electronic devices are adapted to generate cryptographic keys from one or more biometrics. According to one examples, an electronic device can obtain a non-encoded bit string associated with biometric information for an individual. The non-encoded bit string can be treated as if it were encoded and a decoding operation may be applied to the bit string, resulting in a modified bit string. One or more cryptographic keys can then be generated based at least in part on the modified bit string. Other aspects, embodiments, and features are also included.

Abstract: System, apparatus, and methods are provided for protecting against malicious infrastructure in a wireless communication network. A system determines a trust metric for an access point and decides to avoid communication with the access point based on the trust metric for the access point. The trust metric may, for example, be a numeric value such as a probability of trustworthiness or a categorization of trustworthiness. The system may determine the trust metric by receiving a list of access points and their corresponding trust metrics and matching a potential access point to its listed trust metric. The system may try to avoid using an untrustworthy access point's services unless it deems the services important enough to risk the communication.

Abstract: In an embodiment, search parameters in a series of search queries directed to a target node of a semi-structured database are categorized as frequently recurring parameters. A partial search query template is populated with shortcut information related to the search parameters, and then used to facilitate execution of a new search query that includes the same search parameters. In another embodiment, an index is generated that links search parameters that return intermediate search result values to search result values that are configured to be obtained when a search is conducted on the intermediate search result values. The index can be generated based upon monitoring of actual searches within the semi-structured database, or alternatively based upon an inspection of the semi-structured database itself.

Abstract: In an embodiment, a server detects a threshold number of search queries for which the same value at a target node for a document in a semi-structured database is returned as a search result. The server caches the value based on the detection. In another embodiment, the server detects a threshold number of search queries that result in values being returned as search results from a target node. The server caches values at the target node based on the detection. In another embodiment, the server records search result heuristics that indicate a degree to which search results are expected from a set of search queries. The server obtains a merge query and establishes an order in which search queries in the merge query are to be executed based on the recorded search result heuristics.

Abstract: In an embodiment, a server executes a first query in a semi-structured database to determine a first list of nodes that each include at least one node-specific data entry that satisfies the first query. The server initializes a Bloom filter with the first list of nodes. The server filters a list of candidate nodes for a second query based on the Bloom filter. The server executes, in conjunction with a faceted search procedure of a set of documents in the semi-structured database, a second query that uses the filtered list of candidate nodes as a facet to determine a second list of nodes that each includes one or more node-specific data entries from the facet that satisfy the second query.

Abstract: In an embodiment, a server indexes, in a label-path indexed database, a first data entry at a first target node with a given node identifier in accordance with a label-path indexing protocol. After determining that a number of paths from the root node to non-root nodes that share the given node identifier exceeds a threshold, the server indexes a second data entry at a second target node with the given node identifier in a flat-indexed database in accordance with a flat indexing protocol. In an alternative embodiment, the server indexes the first data entry redundantly in both the label-path indexed database and the flat-indexed database while the path number does not exceed the threshold. When the path number exceeds the threshold, the second data entry is indexed in the flat-indexed database only.

Abstract: Methods, systems, and devices are described for wireless communication to enable data collection from wireless devices in an efficient manner. An aspect of the data collection approaches described herein may involve determining a smaller group of wireless devices from which to collect data. Determining the group may be performed such that the data collected is representative of the wireless devices as a whole. For example, a statistically significant group of wireless devices may be selected to be statistically representative of the wireless devices of the network. Various criteria may be identified for selecting the group. Such criteria may include a specified technique for selecting wireless devices for the group.

Abstract: The disclosure relates in some aspects to protecting systems and data from maliciously caused destruction. Data integrity is maintained by monitoring data to detect and prevent potential attacks. A mechanism for tracking whether data is tainted is implemented in a Data Flow computer architecture or some other suitable architecture. In some aspects, a taint checking mechanism is implemented within a register file, memory management, and an instruction set of such an architecture. To this end, an indication of whether the data stored in a given physical memory location is tainted is stored along with the physical memory location. For example, a register can include a bit for a corresponding taint flag, a memory page can include a bit for a corresponding taint flag, and an input/output (I/O) port can include a bit for a corresponding taint flag.

Abstract: Methods and systems for indexing patent related prior art citations are disclosed. Electronic documents can be obtained from one or more patent information systems. An OCR process can be performed on some of the electronic documents. Citations within the documents can be identified and compared to a trusted records list. The citations can be associated with one or more predetermined categories. For example, citations can be categorized into groups such as when a reference is cited (e.g., with original filing, pre and post allowance), who provided the reference (e.g., cited by the applicant, or the examiner), and how the reference is characterized (e.g., statutory basis, combination of references). The citations and corresponding categories can be output to a user or made available for subsequent processing.

Abstract: Embodiments of the disclosure provide efficient hardware dispatching of concurrent functions in multicore processors, and related processor systems, methods, and computer-readable media. In one embodiment, a first instruction indicating an operation requesting a concurrent transfer of program control is detected in a first hardware thread of a multicore processor. A request for the concurrent transfer of program control is enqueued in a hardware first-in-first-out (FIFO) queue. A second instruction indicating an operation dispatching the request for the concurrent transfer of program control in the hardware FIFO queue is detected in a second hardware thread of the multicore processor. The request for the concurrent transfer of program control is dequeued from the hardware FIFO queue, and the concurrent transfer of program control is executed in the second hardware thread.
