Face ID vs/and Touch ID

14 08 2018

It’s always good to have a choice.

I’m not a big fan of the iPhone X’s Face ID (or Face recognition on my Surface Pro4) because it requires you to hold the phone (more or less) directly in front of your face. I prefer the iPhone’s fingerprint scanner on the front or the Nokia’s on the back of the phone. But this is a personal preference thing so I may be in the minority.

I’m not sure about the real reason why Apple didn’t offer two biometric authentication systems. There are lots of circumstances where you can’t use Face ID.

In hospitals or in Asia where I live people often wear a face protection when they got a cold or a viral infection, muslims wear facial veils, bikers wear a helmet and to just look at a message coming in they have to pull it off, outdoor activities may require safety glasses, and, and, and.

And there are also lots of situations in which Touch ID is unusable. What remains then is the old-fashioned way to enter a more or less complex unlock code. A big step backwards in usability.

From a technical point of view smartphones can’t be made a lot better but from a usability aspect there can still be done a lot. Just two examples:

• The FP Scanner of my Nokia 6.1 should be placed nearer to the top of the device.

• Apple should offer both, Touch ID and Face ID.

Companies like Apple, Samsung and Huawei have focused on providing phones with edge-to-edge displays. So in-display fingerprint sensors would allow phones to have full-screen displays with an invisible fingerprint scanning feature.

A device with Touch ID and Face ID could also allow an advanced biometric authentication in that the fingerprint scanning is combined with face recognition giving some kind of 2-Step Authentication for device unlocking and payment release.

Face recognition can only be used to build up more secure multimodal biometric systems which use multiple sensors or biometrics to overcome the limitations of unimodal biometric systems. It can’t entirely replace other techniques.

Hardware does the first step, software the more important second step to identify a person in that it provides algorithms to interpret the data and compare it with a reference image. This can be done accurately or more superficially (like face recognition via “Trusted Face” in Android’s Smart Lock).

I’m waiting for options
in the 2018 iPhone models.

iOS internal Outsourcing Service

for the the quality management of Apple

With the release of iOS 11, Apple developers made too many assumptions, breaking the fragile security/convenience balance and shifting it heavily onto convenience side.

Once an intruder gains access to the user’s iPhone and knows (or recovers) the passcode, there is no single extra layer of protection left. Everything (and I mean, everything) is now completely exposed.

Differential Privacy

29 10 2017

iOS keeps you a Mr or Mrs A.N. Onymous.

Apple started collecting browsing data in Safari using its differential privacy technology.


Hey Tim, you told us multiple times that keeping our privacy is key for Apple. We all thought that Apple is pitching itself as the lone defender of user privacy in a sea of data-hungry companies.

Please explain yourself.

OK, there is a colleague who is a bit more tech-savvy than you so let us here what Craig Federighi has to tell us:

“Differential privacy is a research topic in the area of statistics and data analytics that uses hashing, sub-sampling and noise injection to enable this kind of crowdsourced learning while keeping the information of each individual user completely private.”

Differential privacy isn’t an Apple invention; academics have studied the concept for years. But with the rollout of iOS 10, Apple began using differential privacy to collect and analyze user data from its keyboard, Spotlight, and Notes.
