Samsung Galaxy S10 is the first smartphone with an ultrasonic fingerprint scanner. And against the background of a completely useless unlocking on the face that works on the owner's photos, this option seemed reliable. But not everything is so smooth: the Galaxy S10 can be unlocked using a print on a 3D printer.
This was reported by the user Imgur with the nickname darkshark: he took a photo of his fingerprint on the glass, processed it in Photoshop and created a 3D model. After a printout of 13 minutes (and three adjustments), a 3D print was made that could fool the sensor of the smartphone.
The Samsung Galaxy S10 tried to fool the ultrasonic fingerprint scanner by using 3d printing. It worked.
As noted by darkshark, three minutes are enough for attackers to unlock someone else's smartphone and gain access to personal information, payments, and banking. The only thing needed for this is a print of the victim and access to a 3D printer.
However, this leak is not unique to the Galaxy S10. This way you can unlock other smartphones with a fingerprint scanner. For example, in 2016 the Michigan police used this method to gain access to the murder victim's iPhone.
Earlier, Forbes journalists tested face detection on multiple smartphones using a head printed on a 3D printer.
