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.

Abstract: A set of tracking devices can be placed within a geographic area as part of a scavenger hunt. A user with a mobile device can traverse the area, and when the user moves within a threshold proximity or communicative range of a tracking device, the mobile device can receive a communication from the tracking device identifying the tracking device. In response to determining that the tracking device is part of the set of tracking devices and thus part of the scavenger hunt, the mobile device can modify a tracking device interface displaying a representation of the tracking device to indicate that the tracking device has been found. In response to each tracking device being found, the mobile device can modify the tracking device interface to indicate that the scavenger hunt has been completed.

Abstract: 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.

Abstract: 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.

Abstract: A tracking device can provide a hashed identifier to a mobile device, for instance within an advertisement packet. The mobile device can query each of a plurality of entities with the hashed identifier to identify an entity associated with the hash key used to generate the hashed identifier. In some embodiments, the mobile device can query a centralized key server, which in turn can query the plurality of entities to identify the entity associated with the hash key. The mobile device can then receive a public key from the identified entity, can determine a location of the mobile device, and can encrypt the location with the public key. The mobile device can then provide the hashed identifier and the encrypted location to the identified entity, which can provide the encrypted location to an owner of the tracking device for decryption using a private key corresponding to the public key.

Abstract: One or more features of a tracking device can be disabled if the tracking device is lost. A tracking device is associated with a first mobile device, which can remotely control the tracking device via a tracking server. The tracking server receives an instruction from the first mobile device to disable a feature of the tracking device. The tracking server also receives a notification from a second mobile device that the second mobile device is within a communication range of the tracking device. In response to receiving the instruction and the notification, the tracking server transmits the instruction for the tracking device to disable the feature to the second mobile device. The tracking device receives the instruction to disable the feature from the second mobile device. In response to receiving the instruction to disable the feature, the tracking device disables the feature according to the instruction.

Abstract: A tracking device can use a permanent encryption key pair to encrypt one or more temporary encryption key pairs, which can then be provided to a central tracking system. When a community mobile device subsequently detects the tracking device, the central tracking system provides an encrypted temporary encryption key pair to the community mobile device. The community mobile device uses the encrypted temporary encryption key pair 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 location data, and a device of the user can decrypt the encrypted temporary encryption key pair using the permanent encryption key pair, and can decrypt the location data using the decrypted temporary encryption key pair.

Abstract: A tracking system can provide smart alerts based on a user's location. The tracking system can receive a location of a user's mobile device and establish a geographic boundary around the location if the mobile device remains at the location for a threshold amount of time. The tracking system can receive a new location of the mobile device outside of the geographic boundary and configure the mobile device to scan for a tracking device associated with the user for an interval of time. If the tracking system detects the tracking device within the interval, the tracking system stores information indicating that the user possesses the tracking device. Otherwise, the tracking system sends an indication to the mobile device indicating that the user has left behind the tracking device.

Abstract: A last known location of a tracking device can be determined by using location information received at a tracking system. A disconnection event is received at the tracking system indicating that a tracking device has disconnected from a mobile device. In response, the tracking system can generate a last known location for the tracking device. Other relevant location updates, such as recent locations of the mobile device or locations of other mobile devices that connect to the tracking device are collected and associated with the disconnection event. Based on the location updates, a last known location of the tracking device can be computed and stored.

Abstract: A mobile phone connected to a tracking system detects the presence of a nearby tracking device. If the tracking device is detected for more than a threshold amount of time, the tracking system can instruct the mobile phone to generate a user notification prompting a user to claim ownership of the tracking device. After the user claims ownership of the tracking device, the mobile device provides the ownership claim to the tracking system which can associate the tracking device with that user's account in the tracking system, enabling the user to access features of the tracking device and tracking system reserved for owners of that tracking device.

Abstract: A lost tracking device associated with a tracking system can be located by leveraging one or more community members by inviting these members to join a search party. Search party criteria can be identified and candidate search party members can be selected and invited based on the search party criteria. When invited candidate search party members accept the invitations, they are added to the search party. A last known location of the tracking device can be provided to the search party members, and the search party can remain in effect until the lost tracking device is located. The location of the lost tracking device is provided to the tracking system, which forwards it to the owner of the lost tracking device. A reward can be provided by the owner of the lost tracking device to the tracking system, which releases the reward to the search party member that located the lost tracking device.
