Security and Fingerprint

Linked: Samsung: Anyone’s thumbprint can unlock Galaxy S10 phone

This seems like a pretty major “miss” on security.

“The British couple who discovered the security issue told the Sun newspaper it was a “real concern”.

After buying a £2.70 gel screen protector on eBay, Lisa Neilson registered her right thumbprint and then found her left thumbprint, which was not registered, could also unlock the phone.

She then asked her husband to try and both his thumbs also unlocked it.

And when the screen protector was added to another relative’s phone, the same thing happened.”

I can only imagine the conversations going on at Samsung over this. I’m sure their fingerprint recognition system is great, but they just forgot to test just how it would respond to a small piece of plastic being between the phone and the finger. On the other hand, shouldn’t the default be to not unlock it if it detects something different about the fingerprint, like a piece of plastic?

That’s some poor design right there. If you own one of these phones, be careful about letting it out of your sight, and get upgraded soon.
