In a post on Imgur, user darkshark outlined his project: he took a picture of his fingerprint on a wineglass, processed it in Photoshop and made a model using 3Ds Max that allowed him to extrude the lines in the picture into a 3D version.
Samsung's new flagship device touts what the company considers to be one of the most advanced and secure fingerprint scanners on the market, but it has been fooled by a 3D printed fingerprint. A concern, he notes, is that payment and banking apps are increasingly using the authentication from a fingerprint sensor to unlock, and all he needed to unlock his phone was a photograph, some software, and access to a 3D printer.
"If I steal someone's phone, their fingerprints are already on it". However, the more money you're willing to spend, the better features you get.
Further, tech blogger Jane Manchun Wong recently discovered she was able to use her own face to open her brother's S10+, as the phone apparently found their faces similar enough to unlock. Alongside fixing various security loopholes, the latest software update is said to improve the earphones sound output on the Galaxy A30.
This isn't the first time a phone claiming to be more secure than others has been tricked into unlocking with 3D printed stuff. "There's nothing stopping me from stealing your fingerprints without you ever knowing, then printing gloves with your fingerprints built into them and going and committing a crime", Darkshark said in his post.
One might think this feature is safe.
Neither Samsung nor Qualcomm, which makes the fingerprint sensor technology used in the Galaxy S10, were immediately available for comment.
