Is it possible they are saying that you can’t uniquely identify a person in the population at large based on palm, but you can in a smaller population of people such as registered Amazon go users or ticket holders for a venue? On an iPhone, biometric is being treated as a password where the expectation is that no one but you could open it. For Amazon go, it is just an identifier to a user Plus a data dump of uuids and palms might not be useful information. Maybe there is a effectively a way to hash the raw palm data since this is just effectively a user look up This is pure speculation
