Mobile device to device communications for privacy-preserved retrieval of contextualized mobile device data

摘要

Privacy-preserved retrieval of contextualized mobile device data. A context of a query may be determined. A dissemination point device may be determined based on the context to which to disseminate the query. The query may be transmitted to the dissemination point device, which causes the dissemination point device to trigger a point-to-point communication among mobile devices in search of data that is responsive to the query. That data may be received from one or more of the mobile devices that are determined to be within a geographical range, that store the data that is responsive to the query in the one or more of the mobile devices, and have chosen to provide the data. The data may be received without identifications of the one or more of the mobile devices.

主权项

1. A computer-implemented method for privacy-preserved retrieval of contextualized mobile device data, comprising executing on a processor the steps of:
receiving a query transmitted by a requester; determining a context of the query based on parsing the query to determine at least location information and subject associated with the query; determining a dissemination point device based on the context to which to disseminate the query, the dissemination point device selected from a plurality of registered dissemination point devices, the plurality of registered dissemination point devices comprising characteristic attributes comprising at least geographical location and types of users that pass the geographical location, and the dissemination point device is selected based on comparing the corresponding characteristic attributes with the context of the query; transmitting the query to the dissemination point device and causing the dissemination point device to trigger a point-to-point communication among mobile devices in search of data that is responsive to the query; receiving from one or more of the mobile devices that are determined to be within a geographical range, that store the data that is responsive to the query in said one or more of the mobile devices, and in which respective one or more of users of the one or more mobile devices have authorized retrieving and providing of the data, the data received without identifying the one or more of the mobile devices; and presenting the data to a requester.
