The fingerprint sensor in the Samsung Galaxy S10 appears to mislead with a 3D printed fingerprint of the user. That’s what a user discovered under the name darkshark on Imgur, writes The Verge.
The user described his project on Imgur. To fool the fingerprint scanner, he took a picture of his fingerprint on a wine glass. The photo was processed in Photoshop, after which the user made a model with 3ds Max. With that program, he could convert the lines in the photo into a 3D version.
After 13 minutes of printing – and three attempts with some adjustments each – darkshark was able to make a version of his fingerprint that could mislead the sensor on the phone.
The fingerprint sensor in the Galaxy S10 does not use a capacitive fingerprint scanner used in other versions of the phone. Instead, an ultrasonic sensor is used, which must be more difficult to fool. However, the user shows that it was not difficult to copy his own fingerprint.
One concern is that payment and banking apps are increasingly using fingerprint sensor authentication to unlock. That while all he needed was a picture, some software and access to a 3D printer to get into his own phone. “I can do this whole process in less than three minutes and start the 3D print remotely, so that it’s ready by the time I’m near it.”
Not for the first time
It’s not the first time anyone’s found a way to fool a phone’s sensors. Police officers used a 3D print in 2016 to get into the phone of a murder victim. A security firm used a $150 face mask to bypass Apple’s FaceID on an iPhone X in 2017.
