摘要： The present disclosure relates generally to mechanisms for the estimation of location privacy risk, comprising: building one or more trajectory models from auxiliary information (e.g., one or more maps, one or more routes); capturing common behavioral patterns (e.g., shortest route(s),/fastest route(s)); identifying, given unlinked trajectories for a plurality of users, most likely linkages using the trajectory model(s); eliminating one or more unlikely linkages based on deviation from the shortest route(s) and/or the fastest route(s); measuring privacy as the percentage of linkages correctly identified; and outputting the measured privacy.

摘要： A method, system and computer program for operating and managing data and application services at an edge of a network. An example method includes executing an application on an edge node. The edge node provides services to mobile device end users on the edge of a network. The method may include identifying an operating context for executing an application on an edge node. A management step manages the operation and lifecycle of the application on the edge node in response to the identified operating context.

摘要： Mechanisms are provided for the compact storage of geographical geometries as a collection of points, where individual points are encoded as binary/ternary strings (with the property that points closer to each other share a longer binary/ternary prefix) and the geometry is encoded by compressing the binary/ternary representation of common-prefix points. Mechanisms are also provided for the representation of a geometry using a ternary string that allows efficient storage of arbitrary shapes (e.g., long line segments, oblong polygons) as opposed to binary representations that are more efficient when the geometries are square or nearly square shaped.

摘要： Middleboxes include a processor configured to determine a degree of mismatch between a sequence number in a first connection between the middlebox and a client device and a sequence number in a second connection between the middlebox and a server device. A network control module is configured to delay acknowledgment signals from the middlebox on a connection to decrease the degree of mismatch between sequence numbers and to establish a direct connection between the client device and the server device without mediation by the middlebox upon a determination that the degree of mismatch between sequence numbers is zero.

摘要： Systems, methods, and computer-readable media are described for automatically identifying potential errors in the text output of a domain-agnostic speech-to-text engine and generating text snippets that contain words representative of the potential errors and other words in the neighborhoods of such words for context. In this manner, a substantially reduced amount of text (i.e., the text snippets) can be reviewed for errors in the speech-to-text conversion rather than the entire text output, thereby significantly reducing the burden associated with error identification in the text output.

摘要： A method, system and computer program product are disclosed for providing content to a communications device. In an embodiment of the invention, a communications network receives a first content portion from a content provider and sends the first content portion to the communications device. The communications network also sends a second content portion to the communications device, and this second content portion is customized for the user of the communications device based on selected information about the user that the communications network has. In one embodiment, the communications network uses the selected information about the user to customize the second content portion for the user, and sends the customized second content portion to the communications device. In an embodiment, the communications network sends the selected information to the content provider, and the content provider uses the selected information to customize the second content portion.

摘要： Techniques to adaptively launch/replace applications and services on edge devices in a cellular infrastructure and/or adaptively place content and computation at the edge devices based on logic at the network core are provided. In one aspect, a method for dynamic placement of applications in a cellular network mobile cloud is provided which includes the steps of: (a) obtaining: (i) a model of the cellular network, (ii) a model of user mobility patterns in the cellular network, and (iii) a model of a profile of the applications; (b) upon receipt of requests from users for the applications, obtaining runtime states at edge servers in the mobile cloud; and (c) upon obtaining the runtime states at the edge servers, placing the requests among the edge servers and a core server in the mobile cloud based on the models obtained in step (a) and the runtime states obtained in step (b).

摘要： A mechanism is provided in a data processing system for matching data to a dynamic set of signatures. The mechanism creates a state transition, result, and mask (STR&M) table based on a set of signatures. The mechanism executes scanner code in each of a plurality of hardware devices in parallel to form a plurality of matching engines. The mechanism loads the STR&M table into each of the plurality of matching engines. Responsive to receiving a plurality of input records, the mechanism distributes input strings from the plurality of input records among the plurality of matching engines and receiving signature set match results from the plurality of matching engines.

摘要： A method, system and computer program product for transmitting content across a link in a communications network. In an embodiment, the method comprises examining traffic in the network at a sender end of the link to determine if the traffic is carrying compressed content; when the traffic is carrying compressed content, decompressing at least one portion of the compressed content; and checking a cache to determine if the cache has content matching the at least one decompressed portion of the content. In an embodiment, the method further comprises when the cache has content matching the at least one decompressed portion of the content, determining an identifier associated with the at least one decompressed portion of the content; and using the identifier to reconstruct, at a receiving end of the link, the at least one decompressed portion of the content. In one embodiment, the at least one decompressed portion of the content from the traffic is replaced with an index, the index is compressed to form the associated identifier, and the associated identifier is sent to the receiving end of the link.
