You now unlock anyone’s Galaxy S10 Fingerprint reader with a silicone case

Recently, a couple in the UK found a security bug in the Samsung Galaxy fingerprint scanning. It allows anyone to bypass the fingerprint security to unlock the phone. Even if someone hasn't registered his fingerprint to unlock the device, the silicone case somehow gets confused and lets the user access the phone.

This wasn't the first time when a flaw was detected in the security mechanism of the smartphone. Hackers and security specialists have unlocked the devices using the 3D prints of the fingerprint but to hack the phone, one had access to the phone and fingerprints. In this case, you need only one inexpensive protective case.

Samsung suggests that users should only use the recommended accessories by the company but this doesn't apply to non-authentic users with bad intentions. Galaxy S10 is the first phone to use ultrasonic technology for fingerprint scanning. It creates a 3D map of the fingerprint using ultrasounds, with the reader being embedded under the display panel. Samsung declared for an internal investigation and is working on a fix to be patched as a security patch.

This seems an unbelievable story, but now the word has gotten out. There are videos on YouTube showcasing people shattering the in-display ultrasound technology using just care. This is a major concern for the phones planning to use ultrasonic technology as most of the phones use the optical in-screen fingerprint sensor, which places a CMOS chip under the display and takes a 2D picture of fingerprint. Samsung's biometric solution has failed before with Galaxy S8 in 2017. It was a facial recognition system that had flaws. Anyone could unlock the phone with the picture of the person instead of being an actual person in front of the device camera.
