| > FaceID doesn't "take images of your face and environment" though. From "How Apple's New FaceID Works" at Gizmodo: "Face ID starts with an image of your face, but builds on top of it with the TrueDepth’s dot projector, which will invisibly project over 30,000 dots onto your face each time you look at your phone, creating and building on its map of your features. "'We use the image and the dot pattern to push through neural networks to create a mathematical model of your face,' Apple’s Phil Schiller explained." - https://gizmodo.com/how-apples-new-face-id-works-1803813400 Your objection to my objection might be that FaceID doesn't store the images it takes, but uses them to construct a facial map that it stores instead. But even if that were any better, that's not true, either. From Apple's iOS Security Guide: "Once it confirms the presence of an attentive face, the TrueDepth camera projects and reads over 30,000 infrared dots to form a depth map of the face, along with a 2D infrared image. This data is used to create a sequence of 2D images and depth maps, which are digitally signed and sent to the Secure Enclave." - https://www.apple.com/business/docs/iOS_Security_Guide.pdf The public nature of your face inherently makes access to your phone less secure than the private nature of your fingerprints or even a PIN. But it's not the security of the phone, or the photos or face map stored on it that trouble me. It's the camera-based security paradigm I reject. It reduces resistance to a surveillance society, and increases the incentives for other businesses to use face-identifying software, which destroys privacy in the real world. I don't want people to get used to surrendering their privacy to access their data, and I won't buy a phone that sends a market signal telling the corporate world that I accept these kind of privacy-destroying technologies. Anyway, thanks for the thoughtful response. |
