Publication number: 20230297394Abstract: A device locator mode or find my device (FMD) mode can allow a lost, stolen, or misplaced mobile device to be located. The FMD mode can be enabled or disabled on a mobile device. Sometimes thieves or unauthorized parties attempt to disable the FMD mode. To prevent this, the mobile device can transmit a unique device identifier to a remote server. The remote server can link the device identifier to a cloud-based user account associated with the user of the mobile device. Before an FMD mode is disabled on the mobile device, before the content or settings can be erased, and/or before a mobile device is permitted to be activated/reactivated, a user of the mobile device can be challenged for the credentials of the cloud-based user account. If valid credentials are provided, FMD can be disabled, the content or settings can be reset, and/or the device can be activated/reactivated.Type: ApplicationFiled: May 24, 2023Publication date: September 21, 2023Inventors: Raghunandan K. Pai, Karthik Narayanan, Paul Chinn

Publication number: 20220141623Abstract: In some implementations, a first computing device can send notifications at times that the first computing device is not in an expected location. A user of a second computing device can remotely configure an expected location for the first computing device, which may be a particular location for a certain period of time. During that time, the first computing device can monitor its own location and check whether it is within the expected location. If the first computing device unexpectedly leaves or fails to enter the expected location, the first computing device may transmit a notification to the second computing device. Similarly, if the first computing device loses connectivity with other devices, a server device may notify the second computing device that the location of the first computing device cannot be determined.Type: ApplicationFiled: January 14, 2022Publication date: May 5, 2022Applicant: Apple Inc.Inventors: Andreas E.

Publication number: 20220038819Abstract: 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.Type: ApplicationFiled: June 11, 2021Publication date: February 3, 2022Inventors: Sorin V. Dusan, Raghunandan K. Pai, Scott Lopatin, Tommy Rochette, Navin Bindiganavile Suparna, Emmanuel Lalande, Siva Ganesh Movva, Robert Watson, Scott Grinker

Patent number: 10944571Abstract: 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.Type: GrantFiled: September 29, 2017Date of Patent: March 9, 2021Assignee: Apple Inc.Inventors: Raghunandan K.
