ABSTRACT There are over 2.2 billion Internet users around the world as of December 31 2011, according to the Internet World Stats (IWS) [1]. Online service is an important driving force behind many of today’s Web 2.0 and cloud computing applications. For security and privacy concerns, authentication is utilized by all online services that involve online transactions and restricted information access. Authentication is the process of verifying a user’s credentials when they are requesting services from any secure system. The most commonly form of authentication is the single-factor authentication, which only requires one factor for the user to log into the system. In this case, the username and password together act as a single-factor. A more secure technique is the multi-factor authentication, which requires more than one factor to gain access into a particular system. As the multi-factor authentication getting matured in its currently available methods, hostile actions have been observed against some of the multi-factor authentication techniques. In this paper, we propose a RFID Factor Authentication Application (RFAA); an enhanced technique from SofToken [2] that acts as an improved technique for two-factor authentication. The RFAA not only sustains the next level of security but also is proven to prevent most of security breaches. This RFID enhancement on SofToken is designed especially for computer system access using two-factor authentication to improve the security measure.
