Good luck with that. Think about the problem from the computers point of view. It captures images, including faces, with a camera, essentially making every "real face" a picture of a face. So you're trying to differentiate between a "picture of a real face" and a "picture of a picture of a real face."

i have already thought about it the thing is smartphones now can actually differ
a picture from reality that gives me hope of finding the solution

They also have a camera that dips into the IR spectrum, which a picture won't give the camera anything to see.

Not really a topic for a Quick Answers forum - especially as you have not shared the code that is at fault.

You could start with these CP articles
Introduction to Face Identification[^]
Image Recognition with C# and Emgu Libraries[^]

If you have a specific problem with your code then please do come back ... with the code that is giving you a problem.

You might get more out of engaging with the community forums of whichever face recognition library you are using
