Samsung launched the Galaxy S10 flagship series in February featuring first-ever Ultrasonic in-display fingerprint sensor. At the launch, Samsung advertised various benefits of the Ultrasonic fingerprint sensor including its accuracy and efficiency. Unfortunately, the so-called advanced in-display fingerprint sensor is fooled by an Imgur user dark shark.
The user easily fooled the Galaxy S10 ultrasonic fingerprint sensor by a 3D printed fingerprint. It is quite difficult to believe that a user can go upto such an extent to get into someone’s phone. The fact is the new on-screen fingerprint sensor carries some advancements over optical and capacitive fingerprint sensors, but still, it carries some loopholes.
According to darshark, a fingerprint photograph he took using his smartphone from a wine glass tricked the ultrasonic fingerprint. He used some photoshop skills to optimise photo and added height and depth details in 3DS Max for a 3D print. After doing necessary changes, he printed a 3D images of his fingerprint using AnyCubic Photon LCD resin printer.
Although after some changes involving three times reprinting, the 3D print unlocked the device as like of his actual finger. He believes using a DSLR camera would trick the sensor in a maiden attempt. Improved photography equipment can aid such type of hacks more efficiently and effectively.
This new way to trick fingerprint in-screen fingerprint is raising security questions against the endless safety and security claims from smartphone manufacturers. It pulled the wraps off the next level of security that Samsung has been advertising from past sometime.
However, Samsung Galaxy S10 was launched at Unpacked Event in February. It carries Exynos 9820 Octa-core processor through the world, except for the US where it retails with Qualcomm Snapdragon 855 SoC. It features a triple rear camera module featuring a 12 MP primary shooter + 12MP telephoto lens and a 16 MP ultrawide camera.
