摘要： A tracking device stores identification values unique to the tracking device for use in authenticating the tracking device. When activated, the tracking device provides a first identification value to a first owner and a different identification value to a tracking system. The identification of the tracking device can only be authenticated by combining the identification values given to the owner and tracking system. If a second owner resets the tracking device, the tracking device stores a second version the identification values for use in authenticating the tracking device. In the case that the second owner is illegitimate, (for instance, the tracking device is stolen by the second owner) the first owner can report the tracking device stolen. Upon being reported stolen, the identification value provided to the first owner is transmitted to the tracking system for use with the tracking system identification value to authenticate the first owner, enabling the first owner to locate and recover their stolen device.

摘要： 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.

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.

摘要： 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.

摘要： 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.

摘要： A tracking device broadcasts beacon signals that are separated in time by broadcast intervals. The tracking device determines the broadcast intervals based on a behavior model. The behavior model specifies one or more conditions, such as times of day within a 24-hour day, and associates a usage probability with each condition. A higher usage probability causes the tracking device to broadcast beacon signals at shorter broadcast intervals. A mobile device in communication with the tracking device can reconfigure the behavior model, either by modifying portions of the behavior model or by replacing the behavior model with a different behavior model. This allows the behavior model to adapt to different circumstances, such as different usage patterns during weekdays, weekends, and vacations.

摘要： In one embodiment, a method includes storing, by a tracking server, a hash value for each of one or more tracking devices associated with the tracking server. The method includes receiving, at the tracking server from a user device, a hash value associated with a tracking device, the hash value computed based on a static value uniquely associated with the tracking device and a dynamic value maintained by the tracking device. The method includes identifying, by the tracking server, the tracking device based on a comparison between one of the stored hash values and the received hash value. The method includes updating, by the tracking server, one or more records associated with the identified tracking device based on the receiving the hash value.

摘要： In one embodiment, a method includes receiving, by a tracking system server, an instruction from a first computing device relating to a feature of a second computing device having a tracking component and a functional component. The method includes receiving a notification from a third computing device that the second computing device has received a tracking signal from the tracking component. The method includes, in response to receiving the instruction and the notification, transmitting, by the tracking system server to the third computing device, an instruction for the second computing device relating to the feature, the third computing device configured to provide the instruction to the tracking component of the second computing device.
