Galaxy S10 fingerprint sensor fooled by 3D printed fingerprint

Samsung Galaxy S10 in-display fingerprint sensor

In the days of making smartphones more and more secured for the users smartphone manufacturers are developing advanced features such as fingerprint readers, face mapping, and even sensors that map out the blood veins in the palm of your hand.

But some are finding ways to fool these security measures by multiple processes and one user has found a way to fool the Samsung Galaxy S10 with a 3D print of his fingerprint.

A user named as darkshark posted a project on Imgur, an online image sharing community and image host explaining how he tricked the in-display fingerprint sensor of the Samsung Galaxy S10.

I attempted to fool the new Samsung Galaxy S10’s ultrasonic fingerprint scanner by using 3d printing. I succeeded.

  • Took a picture of his fingerprint on a wineglass.
  • Processed the image using Adobe Photoshop, and then made a model using 3ds Max
  • After 13-minute of printing and three attempts, he prints out the final product to fool the sensor.

Samsung used an ultrasonic sensor in the S10 and S10 plus which is more difficult to fool than capacitive fingerprint scanner. This project definitely raise concerns that now-a-days payment apps uses fingerprint authentications to approve the payment.

This is not the first time someone has spoofed the sensor to get into the devices. Police officers in the US used a 3D print in 2016 to get into a murder victim’s phone, while a cybersecurity firm used a $150 face mask that beat the Apple’s FaceID on an iPhone X in 2017.
