Why it doesn't matter: Galaxy S10 fingerprint scanner cheated by 3D-printed finger

4 min read

If you have lived anywhere other than the last few days, you have done that probably read (not on Pocketfly, because we didn't think it was important) that someone cheated the fingerprint scanner on the Galaxy S10 with a 3D-printed fingerprint. Every blog and their mother … the company's blog and outlet tackled the story, so we thought we'd count why it didn't matter. Not a single bit!

So the original post that started all this is included below, with a short video demo, and says:The ultrasonic fingerprint scanner of the Samsung Galaxy S10 using 3D printing. It worked"That's great! But it doesn't matter at all, maybe except for proof of concept or lab testing scenarios.

Not here to defend Samsung or another company, but here to reassure you that it's OK to buy a Galaxy S10 or another phone despite someone managing to mislead his biometrics with a 3D printed model.

First, an order must have a 3D-printed model, there must be a source for the 3D print to be copied. If someone has access to your fingerprint, you must place an order to create a 3D model that is a hack on your phone. Therefore, do not use this directly on your telephone. Keep your fingers and their prints private. Well, do your best! 😉

Secondly, this is not in proportion to older hacking attempts to unlock a phone with a photo instead of a real face or iris recognition. That is much more accessible. Fingerprint 3D models are much more complicated to replicate, not necessarily talking about the technology needed to replicate them, but the need for a real fingerprint to replicate.

At the end of the day, if you want to put all the CSI on your boyfriend / girlfriend's phone, you already have a huge problem. If your name is FBI, CIA, NSA, MI5, 6, Mossad, FSB or another abbreviated agency, you still need a fingerprint source that you can replicate. You can easily use this and you may even have a 3D printer to use on a Samsung phone. Let's say, as long as you stay away from these entities, it should be fine. No one at the bar can unlock your phone with this method. Neither the Uber / Lift driver after finding your lost phone. Can we go further?
