UraID

Badges and passwords are easy to share or lose, and many biometric systems store raw fingerprint images, which is a serious privacy risk.

An embedded controller reads a fingerprint sensor over UART, extracts minutiae features, hashes them, and verifies against a stored identity record. Raw images are never transmitted or kept. It builds on the biometric attendance work I did at Uralink.

• Only non-reversible feature data leaves the sensor module.
• A hardware abstraction layer allows swapping optical and capacitive sensors.

• Working hardware prototype of the capture and verify flow.
• Privacy-preserving by design.

• C / C++
• Python
• Optical fingerprint sensor
• Cryptographic hashing
