Based on security in distributed systems different resources need security from unknown persons. This paper provides approach for authenticate clients by four factors namely password, smartcard, fingerprint and sms. Here in this paper it is proposed to develop three factor to four factor authentication. Here in this fuzzy logic concept is used to provide better security. By this fuzzy logic, if there is any mismatch or suspicious in fingerprint the server will send one time password to the user mobile and to improve privacy security questions are asked.
