Secure and private cloud based broadcast identification
First Claim
1. A method comprising:
- receiving, at a mobile device from a tracking device, a first value identifying the tracking device and computed using an encoding function based on both
1) one or more characteristics of the tracking device and
2) a time during which the first value is computed, the mobile device associated with one or more tracking devices, the first value computed by the tracking device independent of communications from the mobile device;
computing, by the mobile device and for each tracking device associated with the mobile device, a corresponding second value based on one or more characteristics of the associated tracking device; and
in response to a determination that the received first value does not match any of the computed corresponding second values;
providing the received first value and a location associated with the mobile device or the tracking device to a tracking server, the tracking server configured to determine an identity of the tracking device based on the provided first value, and to store the provided location in association with the determined identity of the tracking device.

Abstract
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.
