Tweedledum and Tweedledee

22 02 2017

Apple’s anniversary iPhone coming in fall 2017 will reportedly bring key technical upgrades including an innovative 3D camera system that can be used for a variety of applications, from biometric authentication to games.

According to KGI Securities’ analyst Ming-Chi Kuo the FaceTime camera will sport an infrared transmitting and receiving module.

The new system will enable the forward facing camera to accomplish 3D sensing and modeling. This will be available for a range of unique use cases, including replacing the head of a character in a 3D game, or taking a 3D selfie.

Of course, such a system could also allow an advanced biometric authentication in that the fingerprint scanning is combined with face recognition giving some kind of 2-Step Amuthentication for device unlocking and payment release.

It will even work with monozygotic and dizygotic twins. They may look like Tweedeldum and Tweedledee but their fingerprints are formed semi-randomly as the foetus develops in the womb and are affected by such things as chance fluctuations of hormone levels. Similarly, the pattern of freckles and moles on the skin is caused by random mutations and will vary between identical twins.

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.

Back to Tweedledum and Tweedledee.
There should always be an option to use a highly secure password to confirm critical actions. The two will learn not to use their birthday.
