Lock 3 · Label Shield

Counterfeits don't get past computer vision.

The model is a MobileNetV3-Small fine-tuned via transfer learning from ImageNet to classify hologram patches as authentic or tampered. Inference runs in under 100 ms on CPU. Uploaded images are never persisted.

POC note. The current model is trained on synthesized hologram patches (300/class) because real label imagery wasn't in the dataset. The architecture, transfer-learning pipeline and inference path are production-ready — retraining on real photographed holograms is a 1-day exercise once those images are available.
