Obscuring true location for location-based services |
摘要 |
A location of a client device may be obscured by using generated random offsets and/or a set of regions. In one implementation, the location of a client device may be obscured using a first random offset and a second random offset. A pseudo-location may be determined based on the location of the client device, the first random offset, and the second random offset. The pseudo-location may be transmitted to a third-party for a location-based service. In another implementation, the location of a client device may be obscured using a first random offset and a set of regions. An intermediate location may be determined based on the location of the client device and the first random offset. A region of the set of regions may be determined based on the intermediate location. A pseudo-location may be transmitted to a third-party for a location-based service based on the determined region. |

1. A method for obscuring a location of a client device comprising:
receiving, at one or more data processors of a trusted server, a location from a client device; generating, using the one or more data processors, a first random offset on a periodic basis; generating, using the one or more data processors, a second random offset responsive to receiving the location from the client device; generating, using the one or more data processors, a pseudo-location for the client device based on the received location, the first random offset, and the second random offset; and transmitting the generated pseudo-location to the client device for a location-based service. |
