Secrecy is often controversial, depending on the content of the secret, the group or people keeping the secret.
(b) Authentication: It is a process in which the credentials provided are compared to those on file in a database of authorized users’ information on a local operating system or within an authentication server. If the credentials match, the process is completed and the user is granted authorization for access.
