Can I see any samples of digital doppelganger photos. The one on the website does not like a photo of 2 separate people.

Well, that's the point. > Such manipulation of photos is typically invisible to the human eye, the researchers found. (The picture in the article is just a file photo of a passport, though. Not an example of the manipulation.)

  That quote strikes me as an incorrect interpretation of whatever the researchers said

  Is this some sort of adversarial image? Wouldn't it only work on specific neural networks?

    Adversarial against humans; it sounds like the idea is to take two people who already look somewhat similar and produce a photo which as best as possible looks like either.

    It works on the neural networks inside people's skulls. The point is a passport control officer would wave either of two distinct people through based on the same photo.

      This isn't related to fooling humans. There is no passport control officer. Immigration use automated barriers and facial recognition to match the person to the digital photo on the passport chip. The trick in the article causes the facial recognition algorithm to accept two different people for the same passport.

        About a decade ago we had iris scanning at London Heathrow. You had to register upfront, and the idea was only frequent flyers would be registered, but it was great, the lines were short - you didn't even need to get your passport out. It started getting a bit silly towards the end as unregistered people started clogging up the queues, but it was far faster than the "automatic passport scanning" stuff. Surely that was harder to forge than a passport photo. I assume the company in charge didn't offer enough bribes to the politicians making the decision.

        The trick also fools humans who still exist at all borders, including at automated gates (where humans get to see each comparison although I can't imagine them being to attentive at the end of their shift).

Here's a ten year old art project where they did that: https://artoftheprank.com/2010/06/19/ztohoven-art-collective-launch-citizen-k-identity-swap/ https://artoftheprank.com/2010/06/19/ztohoven-art-collective... There's a video link in the page. Our government reacted precisely the same - passport/national id offices now have cameras.
