You're describing public-key cryptography. Sign a message to prove you know a private key that also authorizes the release of funds. This happens to be exactly the functionality of Bitcoin.
It is debatable whether known public-key cryptography systems will survive attack for the amount of time under discussion here.
I suspect the hack will be to extract the secret from the brain being resurrected, recover the funds, and toss the brain in the trash.
