Without the reassurance of a handwritten ink signature,
there is no obvious way to verify the authorship.
Alternatively, imagine that a bank receives an e-mail
from a client, which instructs that all the client's funds.
should be transferred to a private numbered bank
account in the Cayman Islands. Once again, without a
handwritten signature, how does the bank know that the
e-mail is really from the client? The e-mail could have
been written by a criminal attempting to divert the
money to his own Cayman Islands bank account. In order
to develop trust on the Internet, it is essential that there
is some form of reliable digital signature.
