Review Paper on Two Factor Authentication Using Mobile Phone (Android)

In this paper we describe the methods for implementing connectionless approach for stronger authentication. This connectionless approach includes the two factor authentication using mobile phone (Android). The main purpose of this method is to provide the stronger authentication in online transaction. Mobile phone is used for the purpose of generation of OTP. It improves the security of Internet payments by providing an additional password to the user. Using the password the user can successfully make his payment. Online card transactions over Internet need enhanced security. Secure processing system facilitates additional security by way of a cardholder-chosen password, which is known only to the cardholder.Dynamic password authentication is one solution that uses the added security ofcredit cards to offer better protection against online fraud. The primary benefit of this system is the reduction in disputed transactions and the resultant exception handling expense and losses.Thus the proposed system is adding an extra layer of security at the point where youenter information online. The service helps to prevent unauthorizedonline use before it happens by confirming your identity with an additionalpassword.
