Apple's Next iPhone: Facial-Recognition, All-Screen Design (theguardian.com)
Apple may have just revealed the features you could expect in the next iPhone. Last week, the company released the firmware of the HomePod, a smart speaker which it will begin selling later this year. In the code, the company has accidentally spilled some features about at least one of the iPhone models. Developer Steve Troughton-Smith looked at the code to find that the next iPhone is going to feature facial recognition and a brand new "bezel-less" design. From a report: The near bezel-less design has long been expected, with leaks and rumours suggesting that Apple was following Samsung's design moves with the Galaxy S8 and producing a smartphone that resembles Android-creator Andy Rubin's upcoming Essential phone. Apple is not the first company to use IR-based face recognition as a means of unlocking devices and authenticating users. Microsoft's Windows Hello IR-based face recognition is found in its Surface line as well as Windows 10 computers from other manufacturers.
What's the best dumb flip-phone these days?
Tin can and string.
This is a solved problem only repeated by Samsung's NIH approach. Android's default approach already requires an extra element (the user to blink), but that has also been defeated by flicking rapidly between pictures of a person with eyes open and with eyes closed. However many other vendors have taken an option to only scan on the IR spectrum. E.g. The Surface devices can't be defeated with a photograph, video or similar things. But I will bet you a Marsbar that apple doesn't do it because that would add yet another "unsightly" blemish to it's sacred front bezel in the form of another dot (IR LED) that you can see when you hold the device at a certain angle.
Mind you face-unlock doesn't work for anything secure on many devices. E.g. you can't use Samsung Pay or encryption with face-unlock.
