There are different methods that are developed for authenticating the users. The most common authentication method is text-based passwords. In this method, users are asked to enter their user ID and password. But the traditional text-based passwords are vulnerable to the attacks like shoulder surfing or peeping attack, key loggers, Trojan attacks, phishing, etc. In this paper, an alternative to the static text-based passwords is used to enhance the security of e-commerce transaction. This scheme is called Noisy Passwords. Noisy password technique is resistant to the eves dropping or shoulder surfing. It consists of actual password and variable alphanumeric noise.
