In recent years, smart phone manufacturers have implemented advanced features for users to secure their devices, using fingerprint readers, face mapping and even sensors that trace the veins of blood in the palm of the hand . But there are still ways to avoid such measures, and a user discovered that he could trick the fingerprint reader into his Samsung Galaxy S10 with a 3D print of his fingerprint.
In a post on Imgur, the darkshark user described his project: he took a picture of his fingerprint in a wine glass, processed it in Photoshop and made a model with 3ds Max that allowed him to extrude the lines of the image in a 3D version After a 13-minute impression (and three attempts with some adjustments), he was able to print a version of his fingerprint that tricked the phone's sensor.
The fingerprint sensor of the Galaxy S10 is not based on a capacitive fingerprint scanner that has been used in other versions of the phone, but uses an ultrasonic sensor that is apparently harder to fake. Darkshark points out that it did not take long to falsify his own fingerprint. One concern, he notes, is that banking and payment applications increasingly use fingerprint sensor authentication to unlock, and all he needed to enter his phone was a photograph, some software and access to a 3D printer. . "I can do this whole process in less than 3 minutes and remotely start 3D printing so that it is done when I get there," he writes.
This is not the first time that someone has found a way to get around the sensors of a telephone. Police officers used a 3D print in 2016 to enter the phone of a murder victim, while a cybersecurity firm used a $ 150 mask to beat Apple's FaceID on an iPhone X in 2017. Like my colleague Russel Brandom noticed a couple of years ago, fingerprints Not as safe as you might think, they can be stolen and falsified, even on the most advanced phones.
