Rumor: iPhone 8 to Replace TouchID with 3D Facial Recognition →

As KGI reports the iPhone 8 will no longer have TouchID, Mark Gurman gives some insider info on Apple's development of 3D Facial Recognition:

For its redesigned iPhone, set to go on sale later this year, Apple is testing an improved security system that allows users to log in, authenticate payments, and launch secure apps by scanning their face, according to people familiar with the product. This is powered by a new 3-D sensor, added the people, who asked not to be identified discussing technology that’s still in development. The company is also testing eye scanning to augment the system, one of the people said.

The sensor’s speed and accuracy are focal points of the feature. It can scan a user’s face and unlock the iPhone within a few hundred milliseconds, the person said. It is designed to work even if the device is laying flat on a table, rather than just close up to the face. The feature is still being tested and may not appear with the new device. However, the intent is for it to replace the Touch ID fingerprint scanner, according to the person.

The intention sounds promising, but I have concerns about this. If true, Apple would be putting their entire security technology in one basket and security reputation on the line. There would be a lot riding on this, especially with their Apple Pay initiative.

So far, facial recognition has been proven insecure and easily fooled by printed selfies. While Samsung S8's Iris Scanner is in improvement in technology, the requirement of facing the phone at a very specific angle and distance weakens the user experience.

Hopefully Apple can pull it off.

iPhone 8 with Iris Scanner? →

Seeing sketchy rumors that iPhone 8 may have an iris scanner like the Samsung Galaxy Note 7. I'm still having a hard time seeing how that it better than a fingerprint scanner under the touch screen.

But to Samsung's credit, the most interesting part of having both a fingerprint scanner and an iris scanner is the software aspect — two tiers of security and authentication. Works great for parents who need to protect access to certain data while giving their kids freedom to play games.

A more Apple solution would be to simply let different fingerprints unlock different things instead.
