Hackers successfully bypass Samsung Galaxy S8’s iris scanner

A group of hackers was able to bypass iris recognition system of the Samsung Galaxy S8, proving that biometric authentication systems are not foolproof.

The hackers of the Chaos Computer Club (CCC) was able to successfully bypass the Galaxy S8’s iris scanner using a fake iris. To make one, they simply captured the device owner’s eye with a digital camera in Night Mode, printed it on paper, then placed a normal contact lens on top of the print to emulate the curvature of a real eye’s surface. What the video below.


“If you value the data on your phone – and possibly want to even use it for payment – using the traditional PIN-protection is a safer approach than using body features for authentication,” says Dirk Engling, spokesperson for the CCC. “The security risk to the user from iris recognition is even bigger than with fingerprints as we expose our irises a lot. Under some circumstances, a high-resolution picture from the internet is sufficient to capture an iris.”

    Now this can serve as a warning to S8 users not to use iris scanners for security. PIN and fingerprint are still the safest…

      but I think they can bypass if you can successfully print the iris of the registered person. How can you do it?
      just my thoughts.
