Samsung Galaxy S10 sensor fooled by a 3D-printed fingerprint

Samsung Galaxy S10 sensor fooled by a 3D-printed fingerprint

The individual (nicknamed darkshark) apparently took a photo of his fingerprint on a wineglass and ran it through Photoshop for a viable 3D model base.

Samsung is using a capacitive fingerprint sensor in the Galaxy S10, rather than the slower ultrasonic sensors that other phone makers are using for in-display fingerprint scanners. This wouldn't quite be a first for Samsung though, as the company did launch two distinct Note models a few years ago when it introduced the Note Edge display concept. In 2016, Police officers used a 3D printer to get into the phone of a murder victim, while a cybersecurity firm used a $150 face mask beat Apple's FaceID on an iPhone X in 2017. He then input that fingerprint into 3DS Max to create a 3D model he printed with his 3D printer. However, ways have been discovered to get around such measures and most recently, a user found a way to trick the in-display fingerprint reader on his Samsung Galaxy S10 with a 3D print of his fingerprint.

Globally, the Galaxy S10 5G has already started to become available with South Korea already selling the new phone. Slipping on a pair of gloves to control the test further, his third attempt resulted in the ability to repeatedly unlock the Galaxy S10+. The S10 ended up reading the video as if it were a real face, with no issues to be spoken of. However, the more money you're willing to spend, the better features you get. But the stories around the Galaxy S10 are still worrisome, since if several kinds of security measures can be circumvented in different ways, the personal info stored inside your phone clearly isn't almost as safe as it should be. The emphasis on depth-mapping also extends to the front with one of the two front cameras featuring time-of-flight (ToF) technology. Still, this just goes to show that everything can be fooled, and if you're thinking your phone is secure with an ultrasonic fingerprint scanner, maybe think again, and wipe your fingerprints off of every surface you touch.
