Fingerprint-Based Vehicle Authentication System

Abstract

In recent years, vehicle security has become increasingly important due to the rise in vehicle theft and unauthorized access. Traditional methods such as keys and passwords are often vulnerable to theft, loss, and duplication. To address these issues, a fingerprint- based vehicle authentication system offers a robust, secure, and convenient solution. This system utilizes biometric technology, specifically fingerprint recognition, to authenticate and grant access to vehicles. The core component of the system is a fingerprint scanner integrated into the vehicle's entry and ignition systems. When a user attempts to unlock the vehicle or start the engine, the fingerprint scanner captures the fingerprint data and compares it against a stored database of authorized fingerprints. If a match is found, the system grants access; otherwise, access is denied. This method ensures that only individuals with registered fingerprints can operate the vehicle, significantly reducing the risk of unauthorized access and theft. The implementation involves several key technologies: fingerprint sensing, digital signal processing, and secure storage. Fingerprint sensing uses optical, capacitive, or ultrasonic sensors to capture high- resolution images of the fingerprint. Digital signal processing algorithms enhance and extract unique features from these images, converting them into a digital template. This template is then encrypted and stored in a secure database within the vehicle’s onboard computer. During authentication, the captured fingerprint is processed in real time, and its features are compared with the stored templates using pattern-matching algorithms. The system employs advanced encryption and secure communication protocols to protect the fingerprint data from interception and tampering. The benefits of this system include enhanced security, as fingerprints are unique to each individual and difficult to replicate. It also offers convenience by eliminating the need for physical keys and reducing the risk of key-related issues such as loss or theft. Additionally, the system can be integrated with other vehicle security measures, such as GPS tracking and remote immobilization, providing a comprehensive security solution.
