Is Amazon Rekognition able to detect fake photos on identity documents?

On its own it does not have the capability to verify if documents have been tampered with or manipulated . However Rekognition offers some features that can help mitigate the risk of fake photos on identity documents:

1/ Face Liveness: This feature helps detect spoofs like printed photos, digital images, or masks presented to the camera. It can improve the chances of catching a fake document being used in place of a real person.

2/ Face Comparison: You can compare the selfie image of the user with the face in the identity document. This helps ensure they match and reduces the possibility of a different person's ID being used. Or maybe , use the Face Collection feature to take facial images from documents and match them against a collection of known user profiles. Face search APIs can be used for this matching.

3/Implement human review workflows using Sagemaker Ground Truth or Augmented AI to validate any low confidence matches from the above steps. Humans can cross-check for any anomalies or tampering not detected technically.

For more robust onboarding process, it's wise to use Rekognition alongside other security measures.
