WINBIO_REJECT_DETAIL Constants

  • Article

The following constants can be used to specify the reason a biometric fingerprint capture or identification procedure did not succeed.

Constant Description
WINBIO_FP_TOO_HIGH
 The finger scan began too high on the finger.
WINBIO_FP_TOO_LOW
 The finger scan began too low on the finger.
WINBIO_FP_TOO_LEFT
 The finger was too far left during scanning.
WINBIO_FP_TOO_RIGHT
 The finger was too far right during scanning.
WINBIO_FP_TOO_FAST
 The finger was swiped too quickly on the sensor.
WINBIO_FP_TOO_SLOW
 The finger was swiped too slowly on the sensor.
WINBIO_FP_POOR_QUALITY
 The scan quality was too poor.
WINBIO_FP_TOO_SKEWED
 The finger did not pass straight across the sensor.
WINBIO_FP_TOO_SHORT
 Not enough of the finger was scanned.
WINBIO_FP_MERGE_FAILURE
 The fingerprint captures could not be combined.
WINBIO_REJECT_DETAIL_ANTI_SPOOF_MASK
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.
WINBIO_REJECT_DETAIL_POSITION_MASK
This mask covers the range of bits devoted to position errors. This value is supported starting in Windows 10.
WINBIO_REJECT_DETAIL_REASON_MASK
 This mask covers the lower 16 bits where the enumerated reason for the rejection is located. This value is supported starting in Windows 10.
WINBIO_IRIS_POOR_QUALITY
 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.
WINBIO_IRIS_TOO_BRIGHT
 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.
WINBIO_IRIS_TOO_DARK
 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.
WINBIO_IRIS_SPOOF_DETECTED
 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.
WINBIO_IRIS_TOO_SKEWED
 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.
WINBIO_IRIS_TOO_CLOSED
 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.
WINBIO_IRIS_GLARE
 The image includes lens glare. Instruct the user to remove their glasses and scan again. This value is supported starting in Windows 10.
WINBIO_IRIS_DIRTY_LENS
 The camera lens was dirty. Instruct the user to clean the lens and scan again. This value is supported starting in Windows 10.
WINBIO_IRIS_POOR_FOCUS
 This iris is out of focus. This value is supported starting in Windows 10.
WINBIO_IRIS_WRONG_ORIENTATION
 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.
WINBIO_IRIS_TOO_HIGH
 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.
WINBIO_IRIS_TOO_LOW
 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.
WINBIO_IRIS_TOO_LEFT
 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.
WINBIO_IRIS_TOO_RIGHT
 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.
WINBIO_IRIS_TOO_NEAR
 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.
WINBIO_IRIS_TOO_FAR
 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.
WINBIO_FACE_POOR_QUALITY
 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.
WINBIO_FACE_TOO_BRIGHT
 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.
WINBIO_FACE_TOO_DARK
 The image is too dark to get a good match. This value is supported starting in Windows 10.
WINBIO_FACE_SPOOF_DETECTED
 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.
WINBIO_FACE_AMBIGUOUS_TARGET
 Two or more faces are overlapping in camera frame. This value is supported starting in Windows 10.
WINBIO_FACE_EYES_OCCLUDED
 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.
WINBIO_FACE_WRONG_ORIENTATION
 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.
WINBIO_FACE_TOO_HIGH
 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.
WINBIO_FACE_TOO_LOW
 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.
WINBIO_FACE_TOO_LEFT
 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.
WINBIO_FACE_TOO_RIGHT
 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.
WINBIO_FACE_TOO_NEAR
 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.
WINBIO_FACE_TOO_FAR
 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.
