It is apparently easy to fool the ultrasonic fingerprint scanner in Samsung's latest Galaxy S10 as a user posted on Imgur that he able to unlock the smartphone with a 3D print of his fingerprint.
Notably, the new Galaxy S10's fingerprint scanner uses an ultrasonic sensor and doesn't rely on a capacitive fingerprint scanner that's been used in other versions of the phone. The ultrasonic fingerprint sensor is supposed to be more difficult to spoof.
"The user took a picture of his fingerprint on a wineglass, processed it in Photoshop, and made a model using 3ds Max that allowed him to extrude the lines in the picture into a 3D version.
"After a 13-minute print (and three attempts with some tweaks), he was able to print out a version of his fingerprint that fooled the phone's sensor," The Verge reported late on Sunday.
This is not the first time that such an instance has been reported.
Police officers used a 3D print in 2016 to get into a murder victim's phone, while a cybersecurity firm used a $150 face mask to defeat Apple's FaceID on an iPhone X in 2017.
