New App Detects the BT Fingerprint of Smart Glasses and Warns You When Someone Is Using Them Nearby
“Outdoors, the app works within 32 to 50 feet; indoors in crowds, that drops to 10 to 32 feet — enough range to identify a person wearing smart glasses in your vicinity. Nearby Glasses works by flagging Bluetooth SIG assigned numbers, unique alphanumeric codes identifying devices based on their brand. Assigned numbers are mandatory for devices utilizing Bluetooth, meaning that gear made by companies like Luxottica Group SpA — the firm manufacturing Meta’s Ray-Ban Smart Glasses — is at least somewhat identifiable for anyone who knows where to look.”
So, yes not perfect, as you may get false positives if someone is for example walking around the mall wearing their Oculus Rift headset. But it is interesting to see some pushback happening against Big Tech's smart glasses. But this early is still in early release, so I imagine it will mature more still.
