Guy Fools Samsung Galaxy S10’s Ultrasonic Fingerprint Sensor with a 3D-Printed Fingerprint

Imgur’s “darkshark” managed to fool the Samsung Galaxy S10’s ultrasonic fingerprint sensor using just a 3D-printer. Tha’s right, he captured his fingerprint on a wineglass, used Photoshop to clean it up, and then created a model using 3DS Max that was used to extrude the lines in the picture into a 3D version. In the end, it took 13-minutes to print a version of his fingerprint that managed to unlock the smartphone.

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

The S10’s fingerprint sensor doesn’t rely on a capacitive fingerprint scanner found in other models of the phone, but rather uses an ultrasonic sensor that’s apparently more difficult to spoof. Darkshark mentioned that it didn’t take much to spoof his own fingerprint. A concern, he says, is that payment and banking apps are increasingly using the authentication from a fingerprint sensor to unlock, and all he needed to get into his phone was a photograph, some software, and access to a 3D printer.
