WINBIO_REJECT_DETAIL Constants
The following constants can be used to specify the reason a biometric fingerprint capture or identification procedure did not succeed.
Constant | Description |
---|---|
|
The finger scan began too high on the finger. |
|
The finger scan began too low on the finger. |
|
The finger was too far left during scanning. |
|
The finger was too far right during scanning. |
|
The finger was swiped too quickly on the sensor. |
|
The finger was swiped too slowly on the sensor. |
|
The scan quality was too poor. |
|
The finger did not pass straight across the sensor. |
|
Not enough of the finger was scanned. |
|
The fingerprint captures could not be combined. |
|
This mask covers the upper 8 bits of the reject detail value where the proof-of-liveness behaviors are located. This value is supported starting in Windows 10. |
|
This mask covers the range of bits devoted to position errors. This value is supported starting in Windows 10. |
|
This mask covers the lower 16 bits where the enumerated reason for the rejection is located. This value is supported starting in Windows 10. |
|
The conditions caused the camera to capture a poor image. Instruct the user to clean the sensor and scan again. This value is supported starting in Windows 10. |
|
The image includes too much ambient light to get a good match. Instruct the user to ensure that they are no facing another bright light source. This value is supported starting in Windows 10. |
|
The image is too dark to get a good match. Instruct the user to ensure that their iris is not obscured by items such as a veil, dark glasses, or colored contacts. This value is supported starting in Windows 10. |
|
The recognition component believes that the iris is not live, but is coming from a replayed video feed, a photo, or a 3-D sculpture. This value is supported starting in Windows 10. |
|
The user is not looking directly at the camera. Instruct the user to look directly at the camera and scan again. This value is supported starting in Windows 10. |
|
The user's eyelids are obscuring the iris. Instruct the user to open their eyes a little more and scan again. This value is supported starting in Windows 10. |
|
The image includes lens glare. Instruct the user to remove their glasses and scan again. This value is supported starting in Windows 10. |
|
The camera lens was dirty. Instruct the user to clean the lens and scan again. This value is supported starting in Windows 10. |
|
This iris is out of focus. This value is supported starting in Windows 10. |
|
The camera orientation does not match the mandatory orientation that the WINBIO_EXTENDED_SENSOR_INFO structure specifies. Instruct the user to change the camera orientation and scan again. This value is supported starting in Windows 10. |
|
The iris is facing up. Instruct the user to look down a little bit and scan again. This value is supported starting in Windows 10. |
|
The iris is facing down. Instruct the user to look up a little bit and scan again. This value is supported starting in Windows 10. |
|
The iris is too far to the left. Instruct the user to look a little more to the right and scan again. This value is supported starting in Windows 10. |
|
The iris is too far to the right. Instruct the user to look a little more to the left and scan again. This value is supported starting in Windows 10. |
|
The iris is too close to the camera. Instruct the user to move a little further away and scan again. This value is supported starting in Windows 10. |
|
The iris is too far from the camera. Instruct the user to move a little closer and scan again. This value is supported starting in Windows 10. |
|
The conditions caused the camera to capture a poor image. Instruct the user to clean the sensor and scan again. This value is supported starting in Windows 10. |
|
The image includes too much ambient light to get a good match. Instruct the user to ensure that they are no facing another bright light source. This value is supported starting in Windows 10. |
|
The image is too dark to get a good match. This value is supported starting in Windows 10. |
|
The recognition component believes that the face is not live, but is coming from a replayed video feed, a photo, or a 3-D sculpture. This value is supported starting in Windows 10. |
|
Two or more faces are overlapping in camera frame. This value is supported starting in Windows 10. |
|
The user's eyes are occluded. Instruct the user to ensure that their eyes are not obscured by items such as a veil, dark glasses, or colored contacts. This value is supported starting in Windows 10. |
|
The camera orientation does not match the mandatory orientation that the WINBIO_EXTENDED_SENSOR_INFO structure specifies. Instruct the user to change the camera orientation and scan again. This value is supported starting in Windows 10. |
|
The face is facing up. Instruct the user to look down a little bit and scan again. This value is supported starting in Windows 10. |
|
The face is facing down. Instruct the user to look up a little bit and scan again. This value is supported starting in Windows 10. |
|
The face is too far to the left. Instruct the user to move a little more to the right and scan again. This value is supported starting in Windows 10. |
|
The face is too far to the right. Instruct the user to move a little more to the left and scan again. This value is supported starting in Windows 10. |
|
The face is too close to the camera. Instruct the user to move a little further away and scan again. This value is supported starting in Windows 10. |
|
The face is too far from the camera. Instruct the user to move a little closer and scan again. This value is supported starting in Windows 10. |
