| http://www.w3.org/ns/prov#value | - Biometrics are a form of identification , not authentication.It should always be used in conjunction with authentication, not to replace authentication.it is still very usefull , because it saves time : you do not have to fill in your login id : the systems knows who you claim to be, and just requires your password to confirm it.So it can replace the userid , but never the password.
