Abstract

Background: Now a day, data communication plays a vital role in day-to-day life. There is a strong desire to develop and implement more secure authentication protocol to protect secret information against security threats. Method: The paper proposes a Quick Response (QR) code Authentication Protocol (QRAP) using Visual Cryptography. Visual Cryptography (VC) is a model of cryptography split the secret into share images, which prevents the secret image from being altered by using the concepts of the cipher and can reconstruct the secret image by stacking the legitimate share images. Findings: The passwords for authentication are encoded as QR-codes and later encrypted into colour share images. Thus, the colour share images by itself convey no information, but when the shares are combined, the secret password can be revealed. The necessary is that the user needs to handle a device containing a QR-code reader, most probably a Smartphone. The experimental result shows that the proposed QRAP scheme provides secure data communication with less computational complexity. Applications/Improvement: This research work can give a way for providing authentication to all services which are related to electronic devices.

Abstract

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.
