    Galaxy S10 Ultrasonic Fingerprint Sensor Hacked Using 3D Printing

    Samsung launched the Galaxy S10 lineup of smartphones at an event in February. The devices that were announced include the Galaxy S10+, Galaxy S10, Galaxy S10 5G and Galaxy S10e. While the latter used a physical, side mounted fingerprint sensor for unlocking the device, the former three have a new technology onboard. They use an ultrasonic fingerprint scanner made by chipmaker Qualcomm and are the first devices in the world to do so. While Samsung claimed the technology is secure than most fingerprint sensors in the market, fresh reports say otherwise. A user who goes by the name ‘darkshark’ on multimedia sharing website Imgur revealed the ultrasonic fingerprint scanners can be fooled using 3D printing.

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

    The video shared by the user shows a Galaxy S10+ being unlocked using the aforementioned method. A 3D printed fingerprint is kept in front of the smartphone with the user pressing down on it while wearing gloves unlocks the device with ease. In an explanation of how he achieved that, the post read that the user took a photograph of his fingerprint on the side of a glass using a smartphone. Then he increased certain aspects of the image like increasing the contrast and creating an alpha mask using Photoshop software. Using another software, 3Ds Max he then created a 3D model of the fingerprint and then printed it using a 3D printer.

    According to the user, 3D printing the fingerprint took them around 13 minutes. The video was shared as a warning for users of the Galaxy S10. The post also reads that it is possible to imitate a fingerprint from across a room using a DSLR camera with a long focal length. This process is claimed to take only 3 minutes, which can be hazardous for users, as most of their account details and personal information can be accessed as a result. It is also not the very first-time biometric security has been fooled on a smartphone. A similar case occurred with the iPhone X when a 3D face was used to unlock the device via the FaceID technology. 

  • Samsung Galaxy S10 To Not Have The Iris Scanner

    Samsung Galaxy S10 To Not Have The Iris Scanner

    The Samsung Galaxy S10 is the upcoming flagship by Samsung. The smartphone marks the 10th anniversary of the Galaxy S series by Samsung and is therefore bound to be special. Previous leaks of the smartphone have showcased some very exciting features of the Galaxy S10. These include an almost bezel-less display with an in-display camera, among others. Latest reports suggest that Samsung will remove the Iris Scanner on the Galaxy S10. It will instead replaced by an in-display fingerprint sensor.

    More Than Meets the Eye

    Galaxy S9

    The Iris Scanner was first introduced with the Galaxy Note 7, infamous for its faulty batteries, which caused some smartphones to explode. The technology is seen in all the Galaxy Note and Galaxy S devices launched after the Note 7. The Galaxy Tab S4 is the most recent device to sport the Iris Scanner. The Iris Scanner by Samsung promised a high level of security with equally high levels of privacy as well. But now, the technology will make way for something bigger and more important; a larger display.

    Removing the sensor present on the top will ensure that there is more screen real estate on the Samsung Galaxy S10. The device will either have an in-display front-facing camera or a camera cut out on the display. This will make way for more screen real estate while not settling for a notch. Samsung is the only major Smartphone manufacturer who has not adopted the notch yet. We expect for the company to set a new trend with its next smartphone.

    Top 10 Features

    The Samsung Galaxy S10 will now have an ultrasonic in-display fingerprint reader. Almost all the smartphones available in the market today use an optical in-display fingerprint reader. The ultrasonic sensor is much more secure and upto 3x more expensive than its optical counterpart. Qualcomm has already finished the development of this sensor which uses cameras to map the ridges in your fingerprint along with the sweat pores on your fingers. The technology can work well through any type of display and also while in contact with water, sweat or grease.
