MAPPING 
TECHNOLOGY
INTRODUCTION
• Recently, a new patent related to Apple's biometric 
authentication device Face ID was issued. 
• The patent outlines an additional development in facial 
recognition technology, which appeared to be validated 
using facial heat mapping.

SECCURITY
• According to a report, the US Patent and Trademark 
Office awarded the Cupertino based giant the new patent. 
• At the moment, a biometric form of security is a highly 
common feature in most smartphones and exists in one 
form or the other.

FACE ID TECHNOLOGY
• Now, Apple seems to be working on the next gen Face ID 
technology, which maps heat on the users’ face for 
authentication.

FACIAL RECOGNITION 
• Traditionally, the facial recognition technology we see 
today mostly uses the user’s face in a captured image. 
However, a major drawback to this method is that any 
obstruction like glasses, masks, or hair could potentially 
hamper the authentication process.

MAPS HEAT FROM THE USERS’ FACE
• The new Apple patent comes in, which maps heat from 
the users’ face. 
• The occlusion heat map may be in the form of a grid that 
represents different regions of the face’s surface.

UNIQUE FACIAL HEAT 
• A determined value of occlusion for these regions might 
be taken as the unique signature which is recorded by a 
device. 
• Meaning, each persons’ unique facial heat signature can 
be used to unlock an Apple device.

ADVANTAGE
• This could help remove the issues faced by conventional 
facial recognition technology and also enable the 
company to continue using its Face ID system, which has 
become rather impractical after the pandemic due to the 
more common use of face masks.

DETERMINE THE USER'S VIEW 
• The Face ID system can not only be used to identify, but 
can also be used to determine the user's view and take 
action based on it.

APPLICABLE ON MAC COMPUTERS
• Last year, Apple also obtained a patent that is still related 
to Face ID. This technology will be applied in Mac 
computers. That means, this security feature will be 
present on Mac.

IN-SCREEN FINGERPRINT SENSOR 
• Apple might be considering the inclusion of an in-screen 
fingerprint sensor for the upcoming iPhone 13, the 
company’s new patent for authenticating images of users 
with obscured facial features could mean that Apple 
might simply continue with the use of facial biometric 
authentication on their next flagship device.
