Authentication is the process by which a user proves their identity to a system. This proof can take several forms:

# A password known only to the user.

# A digital certificate (a secret key contained in a normal file).

# A physical Smart-Card (similar to a Mondex card) inserted into a special reader.

# A biometric measurement such as a fingerprint.
