Abstract

An electronic device includes an audio capture device operable to receive audio input, a fingerprint sensor operable to receive fingerprint data, and one or more processors, operable with the audio capture device and the fingerprint sensor. The fingerprint sensor can authenticate a person as an authorized user of an electronic device while device commands are being received in the form of audio input to allow for secure voice interactions without requiring a trigger phrase. The fingerprint sensor can be used in combination with the receipt of voice input to perform two-factor authentication. The fingerprint sensor and audio capture device can be used in combination to enroll, or update enrollment, of a user interacting with a voice assistant as well.

First claim

What is claimed is:

1. An electronic device, comprising:
an audio capture device operable to receive audio input;
a fingerprint sensor operable to receive fingerprint data; and
one or more processors, operable with the audio capture device and the fingerprint sensor, the one or more processors configured to execute a control operation in response to a device command preceded by a trigger phrase identified in the audio input when in a first mode of operation;
the one or more processors transitioning from the first mode of operation to a second mode of operation in response to the fingerprint sensor receiving the fingerprint data and executing the control operation in the second mode of operation without requiring the trigger phrase to precede the device command.

2. The electronic device of claim 1 , the one or more processors actuating the audio capture device in response to the fingerprint sensor receiving the fingerprint data.

3. The electronic device of claim 1 , the second mode of operation comprising a normal mode of operation when the fingerprint sensor identifies the fingerprint data as belonging to an authorized user of the electronic device.

4. The electronic device of claim 1 , the second mode of operation comprising a privacy mode of operation when the fingerprint sensor fails to identify the fingerprint data as belonging to an authorized user of the electronic device.

5. The electronic device of claim 4 , further comprising a user interface, the one or more processors requiring capture of at least one additional authentication input by the user interface when both:
the fingerprint sensor fails to identify the fingerprint data as belonging to the authorized user of the electronic device; and
the device command involves private data.

6. The electronic device of claim 5 , the one or more processors executing the control operation involving the private data only when the at least one additional authentication input matches a predefined criterion.

7. The electronic device of claim 4 , the one or more processors executing the control operation in the second mode of operation without requiring the trigger phrase only when the control operation is allowed by device settings of the electronic device.

8. The electronic device of claim 4 , the privacy mode of operation restricting access to at least some information of the electronic device.

9. The electronic device of claim 8 , the at least some information comprising medical information associated with an authorized user of the electronic device.

10. The electronic device of claim 8 , the control operation allowing access to an Internet search engine.

11. The electronic device of claim 8 , the one or more processors determining whether the at least some information is required for the one or more processors to execute the control operation.

12. The electronic device of claim 11 , wherein when the at least some information is required for the one or more processors to execute the control operation, the one or more processors requiring capture of at least one additional authentication input.

13. The electronic device of claim 12 , the one or more processors executing the control operation involving the at least some information only when the at least one additional authentication input matches a predefined criterion.

14. The electronic device of claim 1 , the one or more processors, when in the first mode of operation, executing the control operation when the device command is preceded by the trigger phrase.

15. The electronic device of claim 1 , the one or more processors attempting to authenticate the fingerprint data as belonging to an authorized user of the electronic device in response to the fingerprint sensor receiving the fingerprint data.

16. The electronic device of claim 15 , the electronic device further comprising a memory operable with the one or more processors, the one or more processors attempting to authenticate the fingerprint data by comparing the fingerprint data to one or more predefined authentication references stored in the memory.

17. The electronic device of claim 16 , the one or more processors authenticating the fingerprint data as belonging to the authorized user of the electronic device when the fingerprint data sufficiently matches at least one predefined authentication reference of the one or more predefined authentication references stored in the memory.

18. The electronic device of claim 1 , the device command comprising a call to action.

19. The electronic device of claim 1 , the one or more processors executing the control operation in the second mode of operation without requiring the control operation only while the fingerprint sensor receives the fingerprint data.

20. The electronic device of claim 1 , the one or more processors executing the control operation in the second mode of operation without requiring the trigger phrase only when the fingerprint sensor receives the fingerprint data while the audio input is received.
