New Face ID Technology

September 01, 2019



A facial recognition system is a bio-metric technology used for mapping the facial features, patterns, and/or texture of an individual from a digital image or live video feed for the purpose of identity storage and verification.

The system specifically uses a combination of mathematical analysis and artificial intelligence particularly machine learning algorithms, for the collection, storage, and retrieval of bio-metric data.

How does it work?
Using the iPhone X’s True Depth camera, the system measures the unique biological characteristics of your face and stores a 3D image for future recognition. ‘Your photo is processed to extract your features into the device, and then this template is compared to deny or accept access at a later time,’ Dr Zhang explains.

When the system ‘enrolls’ your face, it uses a Dot Projector that projects 30,000 dots onto your face, creating a very detailed facial map. The camera also captures an infrared image of your face, storing both together. That data ends up in your phone to be used as a comparison – it’s not stored on an Apple database.

Advantages:
  • Security through Bio-metric Authentication
  • Automated Image Recognition
  • Deployment in Security Measures
  • Human-Computer Interaction
  • Equips Devices with Added Functionalities
Disadvantages:
  • Issues about Reliability and Efficiency
  • Further Reports About It Reliability
  • Concerns about Racial Bias
  • Issues with Privacy Laws

Is face ID safe to us?
In my view if you're a normal person, Face ID is basically safe. Apple doesn't actually have any record of your face; using Face ID does not mean that you're "giving Apple your face" like I thought it did. Instead, it only stores a mathematical representation of your face locally, on your personal device.
