Method and system for anonymization in continuous location-based services

摘要

In some embodiments, a computer-implemented method includes receiving a first location-based service (LBS) request from a requesting device. One or more peer devices are selected from a plurality of actual peer devices. A set of false queries is generated, by a computer processor, based on the selected peer devices. Transmitted to a service provider are a real query, representing the first LBS request of the requesting device, and the set of false queries representing the selected peer devices. A set of query responses are received from the service provider. From the set of query responses, a real query response is extracted, corresponding to the real query. The real query response is transmitted to the requesting device in reply to the first LBS request.

1. A computer-implemented method, comprising:
receiving a first location-based service (LBS) request from a requesting device; selecting one or more peer devices from a plurality of actual peer devices; generating, by a computer processor, a set of false queries based on the selected peer devices; transmitting to a service provider a real query, representing the first LBS request of the requesting device, and the set of false queries representing the selected peer devices, wherein the real query includes a place-of-interest related to the LBS request, and wherein at least one of the false queries includes a false place-of-interest distinct from the place-of-interest included in the real query; receiving a set of query responses from the service provider; extracting, from the set of query responses, a real query response corresponding to the real query; and transmitting the real query response to the requesting device in reply to the first LBS request.
