Abstract

A fingerprint sensing system. The fingerprint sensing system includes: at least one sensor; at least one display device; at least one application processor; and at least one secure enclave processor. The application processor(s) receives fingerprint data from the sensor(s) and provides the fingerprint data to the secure enclave processor(s). The secure enclave processor(s) decodes the fingerprint data and provides a signal indicative of at least one matched node. The application processor(s), responsive to receipt of the signal indicative of the matched node(s), presents at least a portion of a synthetic fingerprint image via at least one display device corresponding to the matched node(s).

Claims (36)

1. A method, comprising:

at an electronic device with a display and a fingerprint sensor:

capturing first fingerprint information using the fingerprint sensor;

in response to capturing the first fingerprint information, displaying, on the display, a fingerprint representation with a first portion of the fingerprint representation displayed differently from remaining portions of the fingerprint representation, the remaining portions of the fingerprint representation including a second portion of the fingerprint representation;

after displaying the fingerprint representation with the first portion of the fingerprint representation displayed differently from remaining portions of the fingerprint representation, capturing second fingerprint information using the fingerprint sensor; and

in response to capturing the second fingerprint information, changing an appearance of the second portion of the fingerprint representation.

2. The method of claim 1 , wherein the second portion of the fingerprint representation is changed to be displayed differently from remaining portions of the fingerprint representation other than the first portion of the fingerprint representation and the second portion of the fingerprint representation.

3. The method of claim 1 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed in a same manner.

4. The method of claim 1 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed by changing a property of one or more lines in the fingerprint representation.

5. The method of claim 1 , wherein the fingerprint representation is a graphical element that includes elements that represent fingerprint ridges.

6. The method of claim 5 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed by changing a property of one or more elements that represent fingerprint ridges.

7. The method of claim 6 , wherein the property is a line thickness.

8. An electronic device comprising:

a fingerprint sensor; and

a display;

wherein the electronic device is configured to:

capture first fingerprint information using the fingerprint sensor;

in response to capturing the first fingerprint information, display, on the display, a fingerprint representation with a first portion of the fingerprint representation displayed differently from remaining portions of the fingerprint representation, the remaining portions of the fingerprint representation including a second portion of the fingerprint representation;

after displaying the fingerprint representation with the first portion of the fingerprint representation displayed differently from remaining portions of the fingerprint representation, capture second fingerprint information using the fingerprint sensor; and

in response to capturing the second fingerprint information, change an appearance of the second portion of the fingerprint representation.

9. The electronic device of claim 8 , wherein the second portion of the fingerprint representation is changed to be displayed differently from remaining portions of the fingerprint representation other than the first portion of the fingerprint representation and the second portion of the fingerprint representation.

10. The electronic device of claim 8 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed in the same manner.

11. The electronic device of claim 8 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed by changing a property of one or more lines in the fingerprint representation.

12. The electronic device of claim 8 , wherein the fingerprint representation is a graphical element that includes elements that represent fingerprint ridges.

13. The electronic device of claim 12 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed by changing a property of one or more elements that represent fingerprint ridges.

14. The electronic device of claim 13 , wherein the property is a color.

15. A non-transitory computer readable medium storing instructions that when executed by an electronic device cause the electronic device to:

capture first fingerprint information using a fingerprint sensor;

in response to capturing the first fingerprint information, display, on a display, a fingerprint representation with a first portion of the fingerprint representation displayed differently from remaining portions of the fingerprint representation, the remaining portions of the fingerprint representation including a second portion of the fingerprint representation;

after displaying the fingerprint representation with the first portion of the fingerprint representation displayed differently from remaining portions of the fingerprint representation, capture second fingerprint information using the fingerprint sensor; and

in response to capturing the second fingerprint information, change an appearance of the second portion of the fingerprint representation.

16. The non-transitory computer readable medium of claim 15 , wherein the second portion of the fingerprint representation is changed to be displayed differently from remaining portions of the fingerprint representation other than the first portion of the fingerprint representation and the second portion of the fingerprint representation.

17. The non-transitory computer readable medium of claim 15 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed in the same manner.

18. The non-transitory computer readable medium of claim 15 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed by changing a property of one or more lines in the fingerprint representation.

19. The non-transitory computer readable medium of claim 15 , wherein the fingerprint representation is a graphical element that includes elements that represent fingerprint ridges.

20. The non-transitory computer readable medium of claim 19 , wherein the first portion of the fingerprint representation and the second portion of the fingerprint representation are changed by changing at least one of a dash pattern or a shading of one or more elements that represent fingerprint ridges.
