Abstract
The present disclosure provides methods and apparatus for unlocking an electronic device. In an embodiment, a process causes a device such as a smartphone to receive a sound input from a fixed position microphone and determine if the device should be unlocked based on a comparison of the sound input with a previously defined sound input.
Claims21
A method of unlocking an electronic device, the method comprising:
- receiving a sound input from a microphone associated with the electronic device;
- determining a first plurality of peak amplitudes associated with the sound input;
- determining a first plurality of time intervals associated with the first plurality of peak amplitudes;
- determining if the first plurality of peak amplitudes are within a first range defined by a second plurality of peak amplitudes;
- determining if the first plurality of time intervals are within a second range defined by a second plurality of time intervals;
- and
- unlocking the electronic device if (i) the first plurality of peak amplitudes are within the first range and (ii) the first plurality of time intervals are within the second range.
