How paranoid is it to not use facial recognition on an Iphone?

In our digital age, where convenience often intertwines with concerns of privacy and security, the debate surrounding facial recognition technology has peaked. So some people hesitate to use FaceID on their iPhones. Some enjoy the frictionless authentication it provides, while others shudder at the mere concept of having their facial data stored on their smartphone. But how justified are these concerns? In this blog post, we delve into the question: How paranoid is it to eschew facial recognition on an iPhone? Join us as we unravel the layers of privacy, security, and personal choice in the realm of biometric authentication.
How Does Apple's Face ID Technology Work?

  • Face ID, Apple's facial recognition technology, works by using the TrueDepth camera system, which is located at the top of the display on newer iPhone and iPad models. Here's a simplified overview of how Face ID works:
  • Face detection. When you turn on your device or authenticate with Face ID, the TrueDepth camera system activates. It beams millions of invisible infrared dots onto your face to generate a comprehensive depth map and takes an infrared image of your face.
  • Infrared image. The infrared camera captures an infrared image of your face, which includes both the depth information and the 2D image.
  • Data processing. The captured infrared image and depth map are sent to the device's Secure Enclave, a dedicated security processor. The Secure Enclave processes this data locally on the device, employing complicated algorithms to generate a mathematical representation of your face.
  • Face matching. The mathematical representation of your face is compared against the stored facial data that you previously enrolled during the initial setup of Face ID.
  • Authentication. If there's a match between the mathematical representation of your face and the stored facial data, Face ID authentication is successful, and your device unlocks, or the authenticated action is completed (such as confirming a purchase or accessing a secure app).
