Samsung Galaxy S10 sensor fooled by 3D printed fingerprint

With the promising security features several mobile phones offer nowadays, a Samsung Galaxy S10 user claimed that he managed to fool the device’s ultrasonic fingerprint scanner through a 3D printed fingerprint.

Imgur user Darkshark shared how he was able to unlock his smartphone after 3D-printing his own fingerprint and posted a video of the process.

The user said: “It took me 3 reprints trying to get the right ridge height (and I forgot to mirror the fingerprint on the first one) but yeah, 3rd time was the charm. The 3D print will unlock my phone…in some cases just as well as my actual finger does.”

“This brings up a lot of ethics questions and concerns. There’s nothing stopping me from stealing your fingerprints without you ever knowing, then printing gloves with your fingerprints built into them and going and committing a crime,” Imgur user Darkshark added.

I attempted to fool the new Samsung Galaxy S10’s ultrasonic fingerprint scanner by using 3d printing. I succeeded.

Apart from the user’s attempt to fool authentication systems, police also managed to unlock a phone through a murder victim’s 3D fingerprint model back in 2016.

A cybersecurity firm also used a $150 face mask which was able to trick Apple’s iPhone X Face ID in 2017.
