SECURE AND PRIVATE CLOUD BASED BROADCAST IDENTIFICATION

摘要

A tracking device can securely communicate with a secondary device by generating a hash value based on the identity of the tracking device. If the secondary device cannot resolve the hash value, the hash value can be provided to a tracking server, such as a cloud server, for resolving the hash value. Upon resolving the hash value, the tracking server can store a location of the tracking device in association with the identity of the tracking device. To preserve power, the secondary device can activate location-detection functionality (such as a GPS receive) only in response to the detection of movement of the tracking device, can obtain location information, and can de-activate the location-detection functionality upon providing the location information to the tracking server. The tracking server can associate one or both of a previous location and the current location information based on movement of the tracking device.

主权项

1. A method comprising:
receiving, at a mobile device from a tracking device, a hash value generated based on a set of device parameters associated with the tracking device; computing, by the mobile device, a candidate hash value for each of one or more tracking devices associated with the mobile device based on the set of device parameters; responsive to a determination that the received hash value matches a candidate hash value:
providing an identity of the tracking device and a location associated with the tracking device to a tracking server, the tracking server configured to store the location in association with the tracking device identity; and responsive to a determination that the received hash value does not match a candidate hash value:
providing the received hash value and the location associated with the tracking device to the tracking server, the tracking server configured to determine an identity of the tracking device by matching the received hash value to a hash value associated with a tracking device associated with the tracking server and generated based on the set of device parameters, and to store the determined identity in association with the location.
