Lukáš Čambala Face ID is undoubtedly a smart invention and has found favor with many users. However, there have already been several incidents where Face ID was broken and strangers got into the phone. This is not the case in the latest case, where a man got into his wife's iPhone X without any problems. Because Face ID remembered his face.

Patrik Siwek The situation appears to be very serious, because according to Apple, it is possible to set only one face for user authorization in one iPhone X. Of course, the face of the owner, i.e. the wife, was set in the phone. However, the phone also opened thanks to the face of the husband, who sometimes also used the phone. He claims that by using the phone, the technology itself remembered him. The married couple documented the whole problem in a video, which you can find in the source link.

According to Apple, such a coincidence happens in one in a million cases. The husband then contacted Apple directly, but was told by a representative that this could not happen and that he had to open the phone only with his wife's face. According to Apple, a similar battle could only happen in the case of twins, which is of course meaningless in this case.

Dan Pražák The couple always told each other their codes to unlock the device, and once it was borrowed, Mr. Bland was forced to enter it. As he entered it countless times, Face ID apparently mistakenly identified him as his mistress and subsequently made face unlock available to him. However, Apple did not comment further on the issue. The first version of Face ID seems to bring more problems than good, so we'll have to hope that Apple succeeds in these first "childhood diseases" (hence LG) to be tuned to perfection in the next generation of iPhones.
So what kind of moron is this? ... If both of them know the access code to unlock it, it is clear that Face ID, every time the face is not recognized and the code is subsequently entered, can after some time evaluate both of them as "correct" users... And I don't understand at all why it is solved, if they both know anyway the phone code and they use it for each other... :D If only one of them knew the code, as is normal, this can't happen...
Another tabloid headline and article about shit :)
Exactly! ... and the postscript: "let's hope that it will be solved in the next generation" also really irritates me ... Lukáš Č., please have some compassion for us! :-D
It would be a weakness if Apple didn't claim with 100% certainty that the phone can only remember *one* user. I assume they know what they have programmed and believe me machine learning unlocking decisions based on a single face (user) is significantly easier than for multi-users. The fact that it learns to perceive two completely different faces, that they belong to one user, is probably not right either.
I think they said at the keynote that if FaceID doesn't recognize the user, just enter the code and FaceID will try to remember it. So if the man knows the code, all he has to do is try to unlock the iPhone via FaceID and if he doesn't recognize it, enter the code. And at the same time, the neuron network in A11 bionic learns. Now she got used to it and recognizes two people even if it wasn't the target. Normally, a man should not know the code to her phone and then the neuron would not try to recognize him.
But this is unfortunately very wrong, because it means huge dispersion (variance) in the ML model. Therefore, it will be unlocked by someone else.
But you don't have to worry about that, the individual in question obviously has your password, FaceID is irrelevant anyway.
That's true :) But then someone else who doesn't have the password will probably unlock it.
Only Apple knows how that neural network learns to recognize shape.
The neural network can learn to recognize even more objects.
They wonder if their children can unlock it via FaceID, if they have children :-)
Deciding between it's A, it's not A, is much more reliable and easier to learn than it's A, or B, or C, or neither. That's why Apple also let it be known that it does not yet support multi-user. I'm working on ML, but of course Apple knows exactly how to do it.
Yes, but if the neuron receives confirmation from two different people that it is one person, it will adapt to it.
And that increases the complexity of any model and makes it more prone to false positives. Unless, of course, Apple treated it with some trick.
Apple claims that one in a million is a false positive. Of course, we cannot consider this situation from the article as a false positive, if the man uses the correct code and FaceID considers his shape to be the shape of the owner.
Mr. Topinka wants to say that thanks to the output from the neural network in the form of YES/NO, instead of A, B, C, D, E... the neural network thinks simply as follows:
the owner has a big nose, big ears and an oval face
the neuron network will learn to allow entry to the owner who has these features
the owner's son has the same face, but no different ears
the son of the park owner unlocks the phone with a pin, but the NN learns his face as well, or rather adjusts the model so that it takes both standing ears and normal non-standing ears... and theoretically it takes everything in between, because it needs to be told that it's on the ears it doesn't matter at all :)
and thus the chance of 1:1, which was previously for false positives, will change to a smaller chance, which will be proportional to how many people have the same face, excluding ears of course
FID just has to get involved. Yes, it wouldn't happen with TID. But if I share the code with someone, it doesn't matter, right? For me, FID is great, and I was also afraid of it at first.
The FID is great, I'm already looking forward to the tuned second version of the Xka, which I'm going to buy. I enjoy that these artificial affairs confirm that it works and you need to know a numeric ID or extremely difficult to develop a mockup of a face, or be a one-egg clone :-D
Well, you amused me. It's more of a problem than a benefit. Only a person who has not used this technology in his life can really do that.
It struck me as more trouble than good. A colleague has had an iPhone X since the first week of availability in the Czech Republic. He wouldn't go back to TouchID, he has no problems, none of us (the other 10 people) can get into the phone.
Where does it have more problems than benefits?
The level of articles is close to tabloid.
This is already the second article on Jablíčkář, as from Blesk or Expres :-O First they teach that "really no one needs a mobile phone over 20.000,-" and now we have to throw away everything that has a PID. Cut :-O
