Abstract: Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for location-tracking wireless devices. In an embodiment, a method performed by an electronic device comprises: playing, or initiating the playing of, a sound through a loudspeaker of an accessory device via a communication link. The sound is played at a specified frequency that utilizes a frequency response of the loudspeaker (or loudspeaker plus speaker enclosure). The sound is received through two or more microphones of the electronic device and filtered by one or more filters. The one or more filters are configured to pass the sound at or around the specified frequency and to reduce masking of the sound by ambient noise. The filtered sound is associated with direction data generated from sensor data provided by one or more inertial sensors of the electronic device. In another embodiment, the specified frequency is higher than the maximum human hearing range.

Abstract: Some embodiments provide a method for recovering user data for a device. To initiate recovery, the method sends to a first server a first request including at least (i) a device identifier and (ii) a first set of cryptographic data for a second set of servers with which the first server communicates. If the first server verifies the device identifier with an attestation authority, the method receives from the second set of servers a second set of cryptographic data generated by the second set of servers. After receiving input of a device passcode for the device, the method sends to the first server a second request comprising at least a third set of cryptographic data for the second set of servers generated based on the device passcode. If the first server verifies the device passcode with the second set of servers, the method receives access to the user data.

Abstract: Systems, methods, devices and computer-readable storage mediums are disclosed for managing location sharing requests. In various implementations, a requesting device or a server computer in communication with the requesting device, receives a location sharing request associated with a user and, in response, sends a notification to a companion device associated with the user. A location of the companion device is received from the companion device together with a list of one or more devices associated with the user that are paired with the companion device and a connection status for at least one of the one or more paired devices. The connection status indicates if there is a direct communication link established between the paired device and the companion device. A notification is sent to each disconnected paired device based on the connection status. Each disconnected device that is worn or carried by the user responds with their location.
