Samsung’s Galaxy S10 fingerprint sensor fooled by 3D printed fingerprint

In recent years, smartphone manufacturers have implemented advanced features that help users protect their devices by using fingerprint readers, face mapping, and sensors that represent blood vessels in the palm of the hand. However, there is still a way to do this, and one user has found that the Samsung Galaxy S10 can be used to fake a fingerprint reader for display with a 3D fingerprint.

In Imgur's post, user darkshark outlined the project. I created a model that can take a fingerprint in a glass of wine and process it in Photoshop and use 3ds Max to extrude the lines of a photo into a photo. After 13 minutes of printing (and three attempts with a few operations) he was able to print a fingerprint version that deceived the phone's sensor.

The fingerprint sensor of the Galaxy S10 does not rely on a capacitive fingerprint scanner used in other versions of mobile phones, but instead uses an ultrasonic sensor that is more difficult to spoof. Darkshark says he does not care much when deceiving his fingerprints. His concern is that payment and banking applications are getting more and more using fingerprint sensor authentication, and access to photos, software, and 3D printers is all that is required to get into the phone. "You can do this whole process in 3 minutes and you can start 3D printing remotely so you can finish it up to completion."

This is not the first time anyone has found it. How to get around the sensor of your phone. Police used 3D printing in 2016 to get the victims' phone calls, and cyber security companies beat Apple's FaceID on the iPhone X with a $ 150 face mask in 2017. As my colleague Russell Brandom pointed out two years ago, there is no fingerprint. It is safer than I thought. The most advanced mobile phones can also be stolen or spoofed.
