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).

a fingerprint sensor operatively connected to the second processor and adapted to capture fingerprint data, wherein the second processor is adapted to receive captured fingerprint data and provide a signal indicative of the receipt of the captured fingerprint data and the first processor, responsive to receipt of the signal indicative of the receipt of the captured fingerprint data, is adapted to provide the synthetic fingerprint image to the display with a portion of the synthetic fingerprint image that corresponds to the received fingerprint data displayed differently from the remaining synthetic fingerprint image.

2. The system as in claim 1, wherein providing a signal indicative of the receipt of the captured fingerprint data comprises providing a signal indicative of a fingerprint match based on matching at least a portion of the fingerprint data to at least one fingerprint template stored in the memory.

3. The system as in claim 2, wherein providing the synthetic fingerprint image to the display with a portion of the synthetic fingerprint image that corresponds to the received fingerprint data displayed differently from the remaining synthetic fingerprint image comprises providing the synthetic fingerprint image to the display with a portion of the synthetic fingerprint image that corresponds to the matched fingerprint data displayed differently from the remaining synthetic fingerprint image.

4. The system as in claim 1, wherein the fingerprint sensor is adapted to encrypt the fingerprint data, the first processor is adapted to receive the encrypted fingerprint data from the fingerprint sensor and to provide the encrypted fingerprint data to the second processor, and the second processor is adapted to decrypt the encrypted fingerprint data.

5. The system as in claim 1, wherein the first processor is adapted to display an indicator in the displayed synthetic fingerprint image prior to the fingerprint sensor capturing the fingerprint data, wherein the indicator indicates a portion of a finger to be presented to the fingerprint sensor.

6. The system as in claim 5, wherein the indicator comprises at least one of:

a contoured shape;

a dash pattern of at least a portion of one or more lines in the synthetic fingerprint image;

a color of at least a portion of one or more lines in the synthetic fingerprint image;

7. The system as in claim 3, wherein the first processor displays the portion of the synthetic fingerprint image that corresponds to the matched fingerprint data differently by changing at least one of:

a dash pattern of at least a portion of one or more lines in the synthetic fingerprint image;

a color of at least a portion of one or more lines in the synthetic fingerprint image;

a color of a region of the synthetic fingerprint image;

a shading of at least a portion of one or more lines in the synthetic fingerprint image;
