Face Id
« on: October 14, 2019, 11:27:34 PM »

Anybody else using Face Id?

Must say, I’m impressed.  And unlike Touch Id, it still works when my face is wet.  Or when wearing glasses, or even sunglasses in a darkened room, yet I do need to look directly at it.

I keep trying to fool it by trying to unlock whilst looking away.   But in order to know if it has unlocked I must to use my peripheral vision, so it’s quite hard to see.   My eyes are then gradually drawn closer towards the phone until, just as I can see it out the corner of my eye.... ‘snap’, the padlock opens.   

I’ve heard rumours of rival phone manufacturers being taken aback by the robustness and security of Apple’s Face Id.   The suggestion being that their inferior equivalents could be fooled by a static photograph.  Far be it from me to comment. :D

Nice one, Apple. :)

Is there any way you can protect against the possibility of a mugger grabbing the phone and sticking it in front of your face to gain entry?

I think you can press some side button to turn off the feature and thwart the mugger, that is, if you know about it, can remember and can do what is needed in time. Having the presence of mind and dexterity required might be difficult. I think that if I were out and about in some dubious location (ie the mainland  ;D ) then I would just turn the feature off and turn fingerprint id off too and stick with passwords. I have an iPad Pro v1 with fingerprint reader and an iPad 5, which relies on passwords alone.

It takes a direct glance at the screen to unlock.   Whether that would be easy to resist, or if I’d have the presence of mind to look away, I don’t know.

But if a mugger actually wants to access a phone rather than just steal it, I think he’d actually be more likely to produce a big knife and demand “Tell me the passcode”.  And I’d probably tell him. :'(

I used to feel the same.  But one scenario that’s always slightly worried me with passcodes is... I catch a train to some crime-ridden metropolis, like London, passing the time by playing with my smartphone.

Then, sometime after arriving at destination and leaving the train, I get mugged.   Train passengers have no privacy, so I’d be wondering, was the mugger looking over my shoulder every time I got the phone out, does he know my passcode?

I’d actually prefer to know with some degree of certainty, one way or the other, with the mugger can access my phone.    In that respect, I reckon Face Id wins.  Touch Id too, as I think I’d notice if the mugger had cut off my thumb and taken it with him.

My new phone (Mate 20 Pro) has face ID, but I haven't tried it yet, just use finger print or pass code. I know you can disable face ID and possibly finger print as well by pressing the side button rapidly five times IIRC. I thought at the time it would be rather hard to locate and press the button in a threatening situation.

I also use Avast which has an app locker facility, so any financial apps and settings need an additional code or my finger print for an extra level of security

On my PC I have a Hello camera so can unlock that just by looking at it and it works very well. although haven't tried fooling it with a picture.

Sticking with the perceived threats... I get impression many or maybe most mobile phone thefts these days are attributed snatching by moped riders...   

...Since such phones are presumably engaged on a call, chances are they are already unlocked.


My iMac unlocks automatically when I get close, if I’m wearing my Apple Watch.   Car makers (ref keyless access) could learn a lesson from the technology, as it uses a combination of bluetooth and WiFi.   The WiFi element enforces a ‘time of flight’ restriction on the radio path, meaning the distance bounding is absolute.   Any attempt to extend the range using repeaters just would not work. :)

Hi

@7lm - sorry my post is going off topic but relevant to your last post

I watched a bbc program yesterday re keyless entry to cars and thefts

Apparently newer models now have a 40 second sleep before turning off (ie key is stationary for longer then 40 seconds) so no signal is then been transmitted

Also, to drive the car (not start the car) the key needs to within a short distance of the car or you cannot drive the car even if engine running

Sorry for been of topic

Many thanks

John

Ah, but how is the ‘short distance’ enforced?   If based purely on signal strength, it’s not really being enforced at all, it’s just a very rough guess.

Worth pointing out too that whilst I believe the iMac unlock to be secure, it is not always instantaneous, it can take 3 or 4 seconds.   And occasionally, it just doesn’t work, I have to login the old fashioned way.   That won’t bother computer geeks, but car buyers might expect perfection.

That is also why I avoid contactless payment cards  - I believe (?) the technology relies on strength of the radio signal rather to establish proximity,  than actual distance measurement.  I’m not sure time of flight could even be measured accurately in that application, the expected distances being so close.

I do use the my Apple watch for contactless payments, but that requires a deliberate action on my part, a double tap on the side button.  Imho, more secure than a normal debit card.

Can you clarify that? 

iPhones can (and do, by default) display incoming texts on the lock screen.  I have always disabled it as it seems to me like a bad thing.   Am I missing something?

I suspose its especially easy with the latest trend of holding the phone about a foot away on speaker phone.

No worries.   The thread wasn’t intended to be iPhone specific, other than that Apple seem particularly committed to Face Id and, imo, it works well.    Discussion of security features, Apple or otherwise always interests me, even if I fail to conceal personal bias. :-[

Ok well in regards to android, it depends on the brand of rom.  On oxygen os tho for example you can adjust what appears on the lockscreen, in my experience tho even if you dont specifically restrict what can show it will usually to tell you there is one waiting, but not the contents of the message but if only one is waiting it may show the recipient.  Likewise with calls showing the recipient.  I am not sure if this is affected if you enable unlock security, as I dont use unlock security.

I dont know why I have this line of thinking, a factor for sure is the convenience of getting into the phone quickly.  But I suppose also that if I lose the phone, I see if they have access to my data, the fact I lost the device would concern me more and if its a mugging, I got bigger problems than if they can get into the phone or not.  My phone isnt used for financial transactions, so they wouldnt have access to things like google pay, bank accounts etc.

Android seems to be focusing on fingerprint, pin unlock vs face unlock tho.

Given the standardisation of iOS and apple's better track record vs google for software, I expect an iphone to be more secure in general than an android phone.  Consider how common place it is to root android phones as well.  right now on my phone I have it rooted, xposed framework installed, and it still passes google's safetynet which deems it a safe and secure device to use for things like android pay.
