The new Face ID technology.
Is it a revolutionary invention
Face ID
is a facial recognition system
designed and developed by Apple Inc.
for the iPhone
(X, XR, XS & XS Max) and iPad Pro
(third generation). The successor to Touch ID,
the system allows biometric authentication for unlocking a device,
making payments, and accessing sensitive data, as well as
providing detailed facial expression tracking
for Animoji and other features. Initially released in November 2017 with the iPhone X,
it has since been updated and introduced to all new iPhone and iPad Pro models.
The
Face ID hardware consists of a sensor with three modules; one projects a grid
of small infrared
dots onto a user's face whose name is dot projector, the other module called
the flood illuminator reads the resulting pattern and generates a 3D facial
map, and the third one is the infrared camera which takes an infrared picture
of the user. This map is compared with the registered face using a secure
subsystem, and the user is authenticated if the two faces match sufficiently.
The system can recognize faces with glasses, clothing, makeup, and facial hair,
and adapts to changes in appearance over time.
Face
ID has sparked a number of debates about security and privacy. Apple claims it
is significantly more advanced than Touch ID and has far fewer false positives
in general, though Face ID has shown mixed results when trying to separate
identical twins. Multiple security features largely limit the risk of the
system being bypassed using photos or masks, and only one proof-of-concept
attempt using detailed scans has succeeded. Debate continues over the lack of
legal protections offered by biometric systems as compared to passcode
authentication in the United States. Privacy advocates have also expressed
concern about third-party app developers' access to "rough maps" of
user facial data, despite rigid requirements by Apple of how developers handle
facial data.
I strongly
believe that, face id is revolutionary invention. Moreover, it has changed the
way that exposes our smartphones.
