Wearable computing device authentication using bone conduction
First Claim
1. A computing device configured to be worn on a user'"'"'s head, the computing device comprising:
- a bone conduction speaker configured to contact the user'"'"'s head at a first location thereof, the first location being proximate the skull of the user'"'"'s head;
a bone conduction microphone configured to contact the user'"'"'s head at a second location thereof, the second location being proximate the skull of the user'"'"'s head; and
a processor executing instructions stored in memory to;
transmit a first signal from the speaker for reception by the microphone thereby transmitting sound through the skull, the transmission altering characteristics of the first signal to produce a second signal; and
authenticate the user to the device in the event that characteristics of the second signal match characteristics of a calibration signal.

Abstract
A wearable computing device is authenticated using bone conduction. When a user wears the device, a bone conduction speaker and a bone conduction microphone on the device contact the user'"'"'s head at positions proximate the user'"'"'s skull. A calibration process is performed by transmitting a signal from the speaker through the skull and receiving a calibration signal at the microphone. An authentication process is subsequently performed by transmitting another signal from the speaker through the skull and an authentication signal is received at the microphone. In the event that frequency response characteristics of the authentication signal match the frequency response characteristics of the calibration signal, the user is authenticated and the device is enabled for user interaction without requiring the user to input any additional data.

14. A computer-implemented method comprising:
-
transmitting a first signal from a bone conduction speaker through a user'"'"'s skull, the speaker being positioned at a first location on the user'"'"'s head proximate the skull, the first signal causing sound to transmit through the skull; receiving a second signal at a bone conduction microphone positioned at a second location on the head proximate the skull, the second signal being an altered version of the first signal caused by the sound transmitted through the skull; and authenticating the user to a device in the event that characteristics of the second signal are substantially similar to characteristics of a calibration signal. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A computing device comprising:
-
a bone conduction speaker configured to transmit a first signal through a cavity; a bone conduction microphone configured to receive a second signal, wherein the second signal is an altered version of the first signal caused by the cavity; and a processor executing instructions stored in memory to authenticate a user to the device in the event that characteristics of the second signal are substantially similar to characteristics of a calibration signal; and a headset comprising an eyeglass frame, wherein the speaker and the microphone are attached to the eyeglass frame. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
