ABSTRACT:
In a method of managing a database of existing accounts (214) for account holders (202), each account holder (202) has multiple accounts with one or more account authorities (212) for use of a single device with multiple accounts, with each account of each account holder being associated with a public key of a public-private key pair of that account holder. A record of information pertaining to all accounts of a particular account holder is maintained in a central location by a central key authority. The information for that account includes the public keys of that account holder. The central key authority transfers information from the record for an account holder to a new account authority for which that account holder desires to establish a new account; the central key authority also receives information from account authorities for inclusion in the record centrally maintained for that account holder.
