Maintenance of wireless devices

說明書
When the user or owner of the wireless accessory 201 wishes to locate the accessory, the user or owner can access the device locator UI 204 on the mobile device 102. The device locator UI 204 can be associated with a device locator application or feature of the mobile device 102. The device locator UI 204 may also have a web-based interface that can be accessed from the mobile device 102 or another type of electronic device, such as a laptop or desktop device. The mobile device 102, upon loading the device locator UI 204, can send a request (330) for location data to the device locator server 203. The request 330 can include a set of public key hashes, which can serve as beacon identifiers for the beacon data. The mobile device 102 can generate the set of public keys based on the secret information held by the mobile device 102 and the wireless accessory 201 and the timestamps over which the mobile device 102 wishes to receive location data. In one embodiment the set of public keys is based on the sequence of public keys Pi that are generated based on the anti-tracking secret. The sequence of public keys Pi corresponds to a matching sequence of private keys di. The mobile device 102 can generate the sequence of public keys, as well as the corresponding sequence of public keys di, where i is a counter or timestamp. In one embodiment, the mobile device 102 can generate and send hashes for the previous 24 hours of public keys within the request 330. If no data is found for 24 hours of public keys, the mobile device 102 can send hashed keys for an earlier period, back to a pre-determined location data retention limit.
