| 1    | photo should not be empty                                      |
| 2    | wrong mime-type in input data                                  |

| 4    | can not decode image, check it is valid jpeg or png file       |
| 5    | can not detect face                                            |
| 6    | more than one face detected on photo                           |
| 9    | can not extract features from sample, probably it is too small |

#### Notes

* Score close to 1.0 → highly confident that image is real
* Use with liveness check for enhanced spoof detection
* Ensure good lighting, resolution, and frontal face for best results
