Samsung Galaxy S10’s In-Display Fingerprint Scanner Can Be Fooled

Samsung Galaxy S10 Fingerprint Scanner Fooled By 3D Printing The Galaxy S10’s Ultrasonic Fingerprint Scanner Has Been Fooled

An Imgur user was able to spoof the Galaxy S10 sensor by using a 3D printed fingerprint.

Now that the dust around Samsung's Galaxy S10 series smartphones is settling, the next flagship series from the South Korean tech giant is the obvious focus, both from the company and the tipsters from the tech industry's point of view.

Police officers used a 3D print in 2016 to get into a murder victim's phone, while a cybersecurity firm used a $150 face mask to defeat Apple's FaceID on an iPhone X in 2017. The initial step involved taking a photo of his fingerprint on the side of a wineglass using his smartphone. He then switched over to 3ds Max to create a 3D model of the fingerprint, and sent that information to a 3D printer to print his fingerprint.

The post further suggests that the user is capable of faking fingerprints of multiple users in just three minutes, given the fingerprint is already there on the smartphone.

Samsung didn't immediately respond to a request for comment.

The Aces had been pegged as going for Ionescu, if she became available, or 6-7 Teaira McCowan from Mississippi State. Mulkey gave Ionescu a hug and talked to her for a few moments in the postgame handshake line.

Darkshark pointed out the security concerns that are present if the reader can be easily duped. "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".

"I can do this entire process in less than 3 minutes and remotely start the 3d print so that it's done by the time I get to it", darkshark writes in his post.

'Most banking apps only require fingerprint authentication so I could have all of your info and spend your money in less than 15 minutes if your phone is secured by fingerprint alone, ' the user added.

Unlike most phones that get announced, there's been little in the way of new images of the Galaxy S10 5G and especially when it comes to carrier-flavored ones.

Unlike other devices that rely on 2D capacitive scans, Samsung utilises ultrasonic sensors that capture the 3D contours of fingerprints making it more hard to crack.
