    摘要： Methods and apparatuses are provided for facilitating access controls for digital objects stored within a peer-to-peer overlay network. A privacy-preserving method is provided for matching identities between a first peer node and a second peer node in a peer-to-peer network. Such identity matching may be used, for example, to ascertain whether the first peer node should provide access to certain digital object stored in the peer-to-peer overlay network. Rather than providing its identities in an unprotected format, the second peer may provide its identities to the first peer node in a concealed representation so as to prevent the first peer from learning about non-matching identities. Such concealed representation may be a data structure that cryptographically conceals one or more identities of the second peer node or a user of the second peer node within a shared data space of the data structure.

    摘要： A method, apparatus, and/or system for execution prevention is provided. A state indicator for a first subset of a plurality of memory pages of executable code in a memory device is set to a non-executable state. A state indicator for a second subset of the plurality of memory pages is set to an executable state, where the second subset of the plurality of memory pages includes indirection stubs to functions in the first subset of the plurality of memory pages. Upon execution of an application, a function call is directed to a corresponding indirection stub in the second subset of the plurality of memory pages which modifies the state indicator for a corresponding function in the first subset of the plurality of memory pages prior to directing execution of the called function from the first subset of the plurality of memory pages.

    摘要： An apparatus for wireless communications includes a processing system. The processing system is configured to receive an input sound stream of a user, split the input sound stream into a plurality of frames, classify each of the frames as one selected from the group consisting of a non-speech frame and a speech frame, determine a pitch of each of the frames in a subset of the speech frames, and identify a gender of the user from the determined pitch. To determine the pitch, the processing system is configured to filter the speech frames to compute an error signal, compute an autocorrelation of the error signal, find a maximum autocorrelation value, and set the pitch to an index of the maximum autocorrelation value.

    摘要： A method of position clustering includes maintaining a set of clusters by storing a rectangular boundary of each cluster in the set of clusters, a centroid within each cluster, and a number of the points within each cluster. The method further includes adding a point to a cluster in the set of clusters when the cluster bounds the point by adjusting the rectangular boundary of the cluster, the centroid within the cluster, and the number of the points within the cluster.

    摘要： Disclosed is an apparatus and method to detect vehicle theft. In one embodiment, a processor may be configured to execute instructions to: receive a vehicle detection signal from a vehicle detector; determine whether a vehicle is present or absent based upon the vehicle detection signal; establish an authentication credential after the vehicle is determined to present; and validate the authentication credential to indicate validated parking. If the vehicle is determined to be absent and an authentication credential to un-park the vehicle has not been validated, a notification action may be transmitted to appropriate personnel to indicate that the vehicle has been moved or un-parked without proper authentication.

    摘要： A confidentiality preserving system and method for performing a rank-ordered search and retrieval of contents of a data collection. The system includes at least one computer system including a search and retrieval algorithm using term frequency and/or similar features for rank-ordering selective contents of the data collection, and enabling secure retrieval of the selective contents based on the rank-order. The search and retrieval algorithm includes a baseline algorithm, a partially server oriented algorithm, and/or a fully server oriented algorithm. The partially and/or fully server oriented algorithms use homomorphic and/or order preserving encryption for enabling search capability from a user other than an owner of the contents of the data collection. The confidentiality preserving method includes using term frequency for rank-ordering selective contents of the data collection, and retrieving the selective contents based on the rank-order.
