title: Differentiate QRCode and QRCode's Screenshot / Image using QRCode Reader
body: <p>I am using <strong>QRCodeReaderView</strong> library to scan a QRCode. Everything is working perfect like reading QRCode and getting values.</p>
  
  <p>I did the majors to avoid things such as capturing or screenshooting a QRCode, but there's still a thread that one can take a QRCode's picture from some other mobile device and can use that picture to scan the QRCode.</p>
  
  <p>Is there any chance that while scanning from QRCode Reader / Scanner, I can detect that the QRCode displayed is not a true QRCode but an image of QRCode taken from some other device.</p>
  
  <p>How can I differentiate between ?   </p>
  
  <p><strong>P.S</strong>: As I described above, everything works perfectly, that's why I don't share any code, and what I need here is that if yes then how can I distinguish..</p>
  
  <p><strong>P.S</strong> I need some expert on this please.. I just came across a Project In which there was a face detection scenario, the system was able to distinguish between the real face of a person and the picture of that person.. They were the winners in a competition..<a href="https://i.stack.imgur.com/qD9b2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qD9b2.png" alt="enter image description here"></a></p>
