Database session, remember user, cookies

uhm...I think you mean how do you check that the info on the DB is the same that is at the cookie...

well, I think CI sessions make that check for you, if the info in the DB isn't the same at the cookie then the session is not valid.

To check that just try editing some session info at the database for example with phpmyadmin and then try to authenticate that session. You will realize that it can't be authenticated.
