Advance Authentication System to Avoid Password Cracking Attacks

An Advance Login System is a form of authentication that requires the selection of characters in graphical circle by pressing buttons and color inputted during the registration stage in a graphical user interface. Passwords provide the security mechanism for authentication and protection of services against unwanted access to resources. A graphical based password is one promising alternative of textual passwords. The most common computer authentication method in use today is alphanumerical usernames and passwords. This method has been shown to have significant drawbacks. Users tend to choose memorable passwords that are easy for attackers to guess, but strong system-assigned passwords are difficult for users to remember. But also these schemes are vulnerable to dictionary attack, shoulder surfing attack, accidental login and various password cracking attacks. Using a graphical password, users click on buttons rather than typing alphanumeric characters. Today, the most secure form of authentication is biometrically based but the problem with biometrics is that they are very expensive to use but an alternative which is less expensive and more secure is the use of graphical passwords.
