Abstract
A method provides techniques for device locking using Bluetooth Low Energy Channel Sounding. The method includes receiving, by a processor of an electronic device that includes a Bluetooth Low Energy (BLE) interface, a motion initiation message from a second electronic device while the electronic device is unlocked, the second electronic device being communicatively linked with the electronic device for BLE channel sounding and distance measurement. The method further includes initiating a BLE Channel Sounding (BLECS) process using a distance calculation algorithm, where the BLECS process includes sending periodic channel sounding subevents and obtaining distance measurement results corresponding to the periodic channel sounding subevents. The method includes determining a current distance between the electronic device and the second electronic device based on the distance measurement results, and in response to determining that the current distance exceeds a predetermined distance threshold, invoking a lock screen on the electronic device.
