I'm afraid that none of my friends or family are interested in cryo.

I already created one recognition protocol, but it's more for multiple copies of myself meeting. I suppose it would be easy enough to include an MD5 hash of a keyphrase in this doc.

I already have provisions in place for my other data, which will end up in that "perpetual storage drawer" I mentioned.

Preserving assets while im dead is an entirely different kettle of fish, and assumes that I will have any worth preserving, which, given my financial situation, I don't expect to be the case.
