Agreed, I'm not seeing any protection against simply using fake photoshopped pictures of eyes.

It appears they're envisioning an encrypted microkernel which digests the bio data, generates a public key, and pushes it to a blockchain filled with similar data for the whole world population. So I suppose they could be planning to build some kind of signature into the microkernel itself so that outgoing messages sent from a patched or fraudulent process would be noticed. So I guess that could be used to prevent against the even simpler attack of generating the digests of the biodata, as opposed to the biodata itself.

Still, it all seems pretty hand-wavy.
