Fingerprint-based User Authentication Research Articles

A fingerprint-based user authentication protocol considering both the mobility and security in the telematics environment

With the advance of the Internet and mobile communication techniques, the telematics environment where users in vehicles can use the Internet service has been realized. For the safe driving, however, we propose that user authentication for the Internet service is performed by using the driver's fingerprint, instead of typing his/her password. Since the driver's fingerprint is private information to be protected and the size of the fingerprint information is much larger than that of a typical password, we need a different user authentication protocol for the telematics environment. That is, in addition to the compliance with the standard X9.84 protocol to protect the fingerprint information transmitted, we use the watermarking technique to lessen the privacy threat, and propose a secure and efficient protocol between Access Points (APs) considering the possible hand-off during the authentication in the mobile telematics environment. Based on the experimental measurement of the proposed protocol, we confirm that the fingerprint-based user authentication can be performed in real-time in the telematics environment.

Fingerprint-Based Identity Authentication and Digital Media Protection in Network Environment

Current information security techniques based on cryptography are facing a challenge of lacking the exact connection between cryptographic key and legitimate users. Biometrics, which refers to distinctive physiological and behavioral characteristics of human beings, is a more reliable indicator of identity than traditional authentication system such as passwords-based or tokens-based. However, researches on the seamless integration biometric technologies, e.g., fingerprint recognition, with cryptosystern have not been conducted until recent years. In this paper, we provide an overview of recent advancements in fingerprint recognition algorithm with a special focus on the enhancement of low-quality fingerprints and the matching of the distorted fingerprint images, and discuss two representative methods of key release and key generation scheme based on fingerprints. We also propose two solutions for the application in identity authentication without trustworthy thirdparty in the network environment, and application in digital media protection, aiming to assure the secrecy of fingerprint template and fingerprint-based user authentication.
