This is deeply concerning. No parent should be letting their kids faces be scanned with this. They claim to “delete” the image a videos after the scan, but make no mistake, the signature is saved and will be used to track the child online for the rest of their life. We need to have better protections around biometrics. Surveillance is not the solution we want.
This is a threat model that needs to be discussed more. When you share personal information in a way linked to your identity, you should be aware that that link will exist forever. Can you trust custodians of your data forever?
