What kind of abuse are you imagining? Presumably with this system, the TSA agent's query is like: "Does this person's photo match the photo for the identity they are claiming to be?", and not do something like compare your face to every other person's face and return the most likely identity for your face.

So, in that instance, your evil twin could steal your ID and travel as you, but they could do that before this system was in place anyway.

The article mentions a "one to many" system which is exactly this - it compares you to every face in the database and decides who you are, eliminating the need to show physical ID.

Unless both twins are flying on the same day, you could solve this by rejecting matches of people who don't hold a boarding pass for that airport.

Or you could just require a physical ID as backup if the system can't return a match (due to identical twins or otherwise).

> you could just require a physical ID

It's actually not necessary to have an ID to get through TSA, so please don't encourage it.

True - I suppose the "backup" would be either a physical ID or whatever they do to verify your identity when you don't have an ID.
