Comparison: Our Engine vs. KBY-AI vs. BioID
| Metric | Definition | Our Engine | BioID | KBY-AI |
|---|---|---|---|---|
| APCER (Security) | % of Spoofs Accepted (Lower is better) | 1.0% | 0.0% | 0.0% |
| BPCER (UX) | % of Real Users Rejected (Lower is better) | 2.0% | 60.0% | 76.8% |
| Overall Accuracy | Correct classifications (Higher is better) | 98.5% | 70.0% | 61.8% |
Note: All engines tested on the same 200 images (100 live + 100 spoof). FFHQ live images were pre-validated through face alignment (yaw/pitch/roll checks, single-face requirement, center offset). This ensures only properly-aligned, front-facing images are tested — matching real-world capture conditions.
