In recent years, smartphone manufacturers have been introducing advanced features for users who want to secure their devices, using fingerprint scanners, facial recognition systems, and even sensors that detect the pattern of blood vessels in the palm of your hand. But there are still ways around such measures, and one user found that he could fool the fingerprint scanner on his Samsung Galaxy S10 with a 3D-printed fingerprint.
In a post on Imgur, a user under the pseudonym darkshark described his project: he took a picture of his fingerprint on a glass, processed it in Photoshop and created a model using 3ds Max, which allowed him to make the lines in the image three-dimensional. After 13 minutes of 3D printing (and three attempts with some modifications), he was able to print a version of his fingerprint that fooled the phone's sensor.
The Galaxy S10 does not use the capacitive fingerprint scanner that was previously used, but instead uses an ultrasonic one, which, in theory, is harder to fool. It didn't take long for darkshark to fake, though. He noted that the problem is that payment and banking applications are increasingly using fingerprint authentication to unlock, and all that is needed to access the phone is a photo of the fingerprint, modest skills and access to a 3D printer. . βI can complete this entire process in less than 3 minutes and remotely launch a print that will be ready by the time I get to the 3D printer,β he wrote.
This is certainly not the first time someone has found a way to bypass the phone's sensors. For example, cops used a 3D fingerprint in 2016 to break into a murder victim's phone, and phone facial recognition technologies can often be bypassed with a simple photo (in more advanced cases like Apple's FaceID, with inexpensive masks).
