In just 13 minutes, a movie will be released in which the 'ultrasonic fingerprint sensor' of Samsung smartphone Galaxy S10 is broken

The '

Ultrasonic Fingerprint Scanner ' installed on the flagship model smartphone ' Galaxy S10 ' announced on February 20, 2019 by Samsung is a 3D-printed forged fingerprint, and the movie has been released from the online bulletin board It has been published on Reddit and has had a positive impact such as getting 247 comments and 17,000 points or more upvotes at the time of writing.

I succeeded.: 3Dprinting. I succeeded. I succeeded.: 3Dprinting.

I succeeded.-Succeeded.-Album on Imgur I have tried to fool the new Samsung Galaxy S 10's ultrasonic fingerprint scanner by using 3d printing.

The following movie contains the actual 'ultrasonic fingerprint scanner' breakthrough. It took about 13 minutes for the author to create a forged fingerprint, but in less than 20 seconds of the posted movie, the fingerprint printed on a transparent board has been deauthorized. You can check the situation.

I successe. I succeeded. I succeeded. I succeeded. I succeeded.

The movie starts with a transparent board placed on a smartphone that appears to be a Galaxy S10. The user posted is the user ' darkshark9 '.

The screen lights up when the poster's hand wearing rubber gloves extended from the outside of the screen presses the power button on the smartphone. If you overlay the transparent board on the ultrasonic fingerprint scanner at the bottom of the screen ...

Authentication has been cancelled. To indicate that the poster is wearing rubber gloves and that the poster's finger is not releasing the certification. Since an ultrasonic fingerprint scanner can not be activated unless the display senses a human finger by a

capacitance method , it should not be scanned unless it is a human finger or hand, but according to the contributor rubber gloves are extremely Because it was thin, the certification could be breached simply by pressing a finger over a transparent board over a rubber glove. In the second half of the movie, when a rubber glove actually touches the screen, it is detected and an error occurs.

A series of

posts written by the same poster on the image sharing site Imgur can also show the making of forging fingerprints with a 3D printer. The poster first photographed the fingerprint attached to the wine glass.

The next step is to capture the fingerprint image into Photoshop and increase the contrast.

This software for creating 3DCG called 3ds Max creates 3D data in which the fingerprint is lifted from the board. If you look at the screen you are creating, you can see that the fingerprint is floating like a wave.

Create a fingerprint with a 3D printer based on the created data. The contributor used a 3D printer called '

ANYCUBIC PHOTON ' that purchased for less than $ 400 (about 44,600 yen). It can be purchased at Amazon.co.jp, and it is priced at ¥ 50,9999 at the time of writing.

The 3D printer fingerprint is complete. It actually took only 13 minutes to print this on a 3D printer. All fingerprint images have been processed, and it seems that even if someone forges a fingerprint from this fingerprint image with a 3D printer as well, the author's smartphone authentication can not be cancelled.
