- Not at all -- many banks provide anonomous accounts. The only
- requirement is a secure authentication mechanism that shows
- whoever is withdrawing funds is the person who opened the
- account in the first place. The usual is a number signed in
- longhand, related to, but not the same as the 'account
- number'.

- No bank will give you money just because you belong to a depositor
- organisation. You have to be designated and they must have your
- signature on file. If they have your signature, they won't give a
- tinker's dam for your "true identity". This is functionally
- indistinguishable from having the private key to match the public
- key provided by whoever opened the account.
-
- You may not have noticed the last time you opened an account, but
- I'll bet no one asked you for any proof of identity.
