Objectives: User authentication is an indispensable element for secured network service. Due to the rapid advancement of Internetworking technologies, it is easy for attackers to access confidential data by compromising authentication methods. Traditional methods of biometric authentication have a weakness, especially in high-security systems because it gives chances for any attacker to obtain the system information. There is a strong desire to develop and implement more secure authentication method to protect such information against security threats. Methods: From the existing Biometric authentication methods, DNA (Deoxyribo Nucleic Acid) is said to be the best method due to its high accuracy and allows both identification and verification. At present DNA techniques are used mainly in Law enforcement, there is feasibility to extend this in real life system security. Findings: The proposed D-SSS is an innovative and new idea of DNA pattern extraction and pattern matching approach. Applications: The proposed (D-SSS) DNA-based biometric technique builds a new system of authentication that requires very less amount of saliva to protect the system efficiently with highlevel security. The D-SSS is a user-friendly approach, which uses the unique property that the user has at the time of authentication, will lead to intensive work in the area of system security.
