veinRecon — Biometric Verification
Offline verification of a person's identity from the vein pattern on the back of their hand.

What it does
Verifies who someone is from the vein pattern on the back of their hand, entirely on-device — no network, no server holding biometrics.
How
A MobileNetV2 feature extractor with Siamese and triplet matchers, exported to TFLite so it runs on the device itself.
Evaluation is subject-disjoint: no person appears in both training and test data, so the scores reflect performance on genuinely unseen people rather than memorised individuals. That distinction is the difference between a number that means something and one that doesn't.
Data
I built a custom Arduino-controlled infrared capture rig to collect the dataset, since nothing suitable existed.
