In one embodiment, a method implemented by a computing device includes receiving a tracking signal from a tracking device, and determining an identification of the tracking device based on the tracking signal. The identification includes a unique identifier associated with the tracking device. The method further includes receiving, from a tracking system server, a device identifier and a device command associated with the tracking device. The device command corresponds to a feature of the tracking device. The method further includes determining whether the unique identifier determined by the computing device matches the device identifier received from the tracking system server, and in response to determining that the unique identifier matches the device identifier, transmitting the device command to the tracking device.

A user's departure from a first airport and landing at a second airport can be detected using tracking device functionality. A user's location (determined using a tracking device) is compared to known airport locations to determine that the user is at a first airport, and an aircraft takeoff event can be identified using tracking device movement information (such as speed and acceleration). In response to the detected aircraft takeoff event, a notification is sent to a set of users associated with the user indicating that the user has taken off from the first airport. A user's second location is compared to known airport locations to determine that the user is subsequently at a second airport. An aircraft landing event can be detected using tracking device movement information, and a second notification is sent to the set of users indicating that the user has landed at the second airport.

A mobile device determines based on a signal strength threshold when tracking devices communicatively coupled to the mobile device are lost or left behind. The mobile device communicatively couples to a tracking device and receives a first signal transmitted by the tracking device with a signal strength greater than a signal strength threshold. The mobile device receives a second signal transmitted by the tracking device and determines a measure of signal strength based on the second signal. While the mobile device is still communicatively coupled to the tracking device, and responsive to determining that the measure of signal strength of the second signal is less than the signal strength threshold, the mobile device generates a notification that the tracking device may be lost or left behind to alert the user of the mobile device.

A tracking device can be reconfigured after an amount of operation to preserve the battery capacity of the tracking device and to ensure that the tracking device can be operated for a pre-determined threshold period of time. The tracking device can provide diagnostic information representative of a state of the tracking device, such as a current power capacity of the tracking device's battery, to a mobile device within a threshold proximity of the tracking device. The mobile device can then provide the diagnostic information to a tracking server, which in turn can provide reconfiguration instructions to the mobile device. The mobile device can then pass on the reconfiguration instructions to the tracking device, in response to which the tracking device can reconfigure itself.

A tracking device can use a permanent encryption key pair to encrypt a temporary private key that corresponds to a set of diversified temporary public keys. When a community mobile device subsequently detects the tracking device, the central tracking system provides a diversified temporary public key to the community mobile device. The community mobile device uses the diversified temporary public key to encrypt location data representative of a location of the community mobile device, and provides the encrypted location data to the central tracking system. When a user subsequently requests a location of the tracking device from the central tracking system, the central tracking system provides the encrypted temporary private key and the encrypted location data to a device of the user, and the device can decrypt the encrypted temporary private key using the permanent encryption key pair, and decrypt the encrypted location data using the decrypted temporary private key.

Power can be preserved in a tracking device equipped with a GPS receiver and a transceiver by evaluating the proximity of the tracking device to a mobile device and enabling the GPS receiver and transceiver only in the event that the tracking device is out of the range of the mobile device. Once enabled, the location of the tracking device can be determined based on location information received from the GPS receiver. The determined location can be provided to a tracking system associated with the tracking device. The tracking system can then inform an owner of the tracking device of the determined location. Once the tracking device has been found, the GPS receiver and the transceiver can be disabled to save additional power.

A method comprises accessing historical signal and other information received from a tracking device configured to scan for signals transmitted by local devices and record other data as the tracking device moves within the geographic area during each of a plurality time intervals. A training dataset is generated based on the historical signal and other information and used to train a machine learning model configured to predict tracking device movement patterns. The machine learning model is applied to current signal and other information to detect a variance from one or more predefined routines associated with the tracking device. A notification is sent to a monitoring device associated with the tracking device in response to detecting the variance from the one or more predefined routines associated with the tracking device.

A method for receiving, by a mobile computing device, a request from a tracking device associated with the mobile computing device, the request indicating a detected movement of the tracking device, determining, by the mobile computing device, and based on a timestamp associated with the detected movement of the tracking device, whether the tracking device has moved from a previously determined high-accuracy location of the tracking device, and in response to determining that the tracking device has moved from the previously determined high-accuracy location, associating, by the mobile computing device, and based at least in part on whether the tracking device is within a threshold distance from the mobile computing device, the tracking device with a location of the mobile computing device, and designating, by the mobile computing device, the location of the mobile computing device as a current high-accuracy location for the tracking device.

Communication between an owner of a lost tracking device and a finder of a lost tracking device is established. A tracking system receives an identifier of a tracking device and a request for a web page from a mobile device that has captured an image of a smart code on the tracking device. The smart code is embedded with a URL to the web page. The system displays the web page on the mobile device and prompts the user to provide a location of the mobile device. The location is associated with the identifier of the tracking device. A notification indicating the location of the tracking device is generated for the owner. The owner is prompted to provide information to establish contact with the finder of the device, and the web page is populated with the owner's provided information for display on the finder's mobile device.
