“Because Face ID is attention-based, much like voice recognition systems, this means some aspect of the technology has to always be on. Some are creeped out by the idea of facial recognition system potentially scanning everything it sees, which seems like a legitimate concern.
“The increasing usage of biometrics for consumer security will likely reignite the Apple vs. FBI debate. Some also fear that easy-to-use biometric systems, like Face ID, might wind up being used against consumers if they’re put into situations where they’re unable to act quickly enough to disable Face ID and are compelled to unlock their phone against their will.”
“Although Apple says it’s worked with Hollywood makeup and design artists to tests its systems against spoofed faces, it’s getting frighteningly easier to create facial molds and models. For example, in 2013, artist Heather Dewey-Hagborg created an art exhibit using residual DNA from leftover hair and other artifacts to 3D print the faces of strangers. Her exhibit was created to demonstrate the amount of information we tend to leave behind and how we’ll need to carefully guard it from the surveillance systems of the future. With 3D printing and DNA phenotyping becoming more common, the long-term viability of facial recognition as a security measure is at the very least questionable.”
Worse, Face ID has a single point of failure, your face. Should you lose to mathematical model that the tech relies on to a hack, you can’t exactly change your face like you can a password.
“Because so many of the concerns surrounding Face ID are speculative, it’s extremely difficult to say. While it’s likely that individuals using Face ID will make their devices more secure, in a broader sense, an argument could be made that the privacy implications of introducing this technology for society as a whole are currently unknown.”
Imagine if you are drunk or stoned. The nosy, jealous gf is ready to flash your phone to unlock it with just a gaze? Nah. Passcode it is.
