Common Causes of 'Invalid Face Image' Errors

When dealing with face image validation errors, the problem often lies in the quality or nature of the selfie image uploaded by the user. Here are the criteria that typically result in an invalid face image:

Face Obstruction: The user's face is partially or fully blocked by other objects.

Wearing Accessories: The selfie is taken while wearing objects that block the user's full face, such as masks or glasses.

Multiple Faces: There are multiple faces in one selfie frame.

Secondary Device Images: The selfie is taken from another device (e.g., a photo of a photo on another mobile phone).

Distance Issues: The selfie is taken too far away, showing the full body instead of just the face.

Poor Lighting: The selfie is taken in poor lighting conditions, making the face difficult to recognize.

Image Rotation: The selfie image is rotated, making it difficult for the system to process.

Resolution Steps

To resolve the "Invalid face image" error, ensure that the selfie image uploaded by the user adheres to the following criteria:

Direct Capture: The selfie photo should be taken directly (not a file uploaded from the user's side).
Full Face Visibility: The image should show the whole face, including the eyes, nose, and mouth.
Good Lighting: The selfie should be taken in good lighting conditions to ensure the face is clearly visible.

Directly Captured: The photo must be taken directly by the device being used for the ID validation.
