Abstract
A biometric device formed on an integrated circuit is disclosed. The biometric device includes a CMOS image sensor, a microprocessor, and non-volatile memory.
Claims8
A biometric device formed on an integrated circuit, said biometric device including a CMOS image sensor formed on said integrated circuit, a microprocessor formed on said integrated circuit, and non-volatile memory formed on said integrated circuit.
A biometric device, comprising:
- a CMOS image sensor formed on an integrated circuit, the CMOS image sensor configured to capture raw image data of a physiological characteristic of a candidate user;
- non-volatile memory formed on the integrated circuit, the non-volatile memory capable to store a template that identifies an authorized user;
- and
- a microprocessor formed on the integrated circuit, the microprocessor capable to extract a feature set from the raw image data, to compare the feature set to the template, and to generate an unlock command if the feature set is substantially similar to the template.
