The QR code includes a hash of the photo so that anyone that chooses to apply a public template and hash to the photo can verify. Each QR code might use a slightly different photo that is still recognizable to the verifier but the hash would be different to avoid correlation. This would have to be paired with strict rules about verifiers saving the photo. Adrian
