Exciting technology such as face recognition makes our smartphones more functional than ever, but at what cost? We learn that there are different ways to play the software, making your data and information vulnerable to attacks. So how can you protect yourself?
Fortunately, there are some steps you can take to make face unlocking on your Galaxy S1
Setting face recognition
If you want a second way to unlock your phone, you can enable face recognition by going to Settings> Biometrics and security> Face recognition. When the screen is turned on on one of the S10 telephones, you will see a light around the hole punch camera (the selfie camera that floats on the screen at the top right). This means that the camera is looking at your face and as soon as it finds it, the phone is unlocked. You can set it to jump directly to the home screen by turning off Disable on Lock Screen.
The problem is that the technology is very basic and that means that it is not very safe. A simple trick to show the camera a picture of your face – printed or on another phone – is fooling him to unlock the phone. Take a look at our test in the tweet below:
So yes, the # GalaxyS10 can be unlocked with an image of your face. BUT go to Settings & gt; Biometrics and security & gt; Face recognition and switching off "Faster recognition." Since then I have not been able to fool with an image, and the speed difference does not feel so much slower. pic.twitter.com/n13sEmn8mt  & mdash; Julian Chokkattu (@JulianChokkattu) March 7, 2019
We've focused images of our faces toward the selfie camera of the Galaxy S10 and it can never be unlocked. That is a bit alarming, even if Samsung clearly indicates that face recognition is not safe. Face recognition on the S10 series will never be safe enough to use as a verification method for sensitive apps, but there is a way to make it less easy to fake.
In Settings> Biometrics and security> Turn off face recognition, Faster recognition. What this does is, face recognition is a bit slower, but a bit safer, so it's not fooled with just a picture of your face. In addition to the option Faster recognition it warns: "Faster recognition improves speed but reduces security, which increases the chance that a video or image will be recognized as your face incorrectly."
We turned it over and then tried to fake it with the same test as before, but the phone did not unlock at all. The difference in speed is also negligible. Now we are not saying that it will not be sensitive to spoofing, but it should provide a little more peace of mind if you still want to use Face Unlock.
Ultimately, if Samsung's face recognition protection worries you a bit, it's probably a better idea not to use it at all and just stick with the fingerprint sensor.
