                         Basically there are two types of security measures:
                           User Identification: A user can login to the account with his account number only.
                            The PIN system: PIN stands for Personal Identification Number. It is the secret password that should
                             remain with the account holder only. It is used to login to the account.

                            Signature based e-Banking: In this system, the authentication  of the account  holder  is checked
                             digitally. In such system the signature or authentication is encrypted in a media like smart cards or
                             storage media. While doing the banking transaction, the account holder has to insert the media in the
                             host workstation which can authenticate the users to open the account.
