Unlocking a wireless device using image analysis and liveliness detection

An electronic device comprising:

• a camera;
• one or more antennas;
• one or more processors;
• and
• one or more computer readable media storing processor executable instructions which, when executed using the one or more processors, cause the electronic device to perform operations comprising:
• determining, based on image data generated using the camera, recognition data indicating that the image data depicts an authorized person,
• causing transmission, using at least one of the one or more antennas, of a first signal representing a frequency modulated continuous wave signal,
• determining, based on one or more signals received using the one of the one or more antennas that represent a reflection of the frequency modulated continuous wave signal:
• frequency bin data indicating a plurality of frequency bins each corresponding to a distance;
• and
• angle of arrival data,
• determining, based on the frequency bin data and the angle of arrival data, liveliness data indicating that a person is disposed in front of the camera, and
• transitioning to an unlocked mode based on the recognition data and the liveliness data.
