Abstract
Better access control system security comes at a higher price. It many cases the price is too high for small companies, leaving them vulnerable with cheap and insecure systems. In this work we introduce an alternative access control scheme, which improves access control security while lowering the cost. In the proposed model, passive RFID tags are mounted near a turnstile or a smart door. Tag reading and programming is done via NFC chip directly on the users smartphone. To enhance security, together with smartphone-based authorization we require the user to provide his photograph while entering a secure gate. The photograph is then displayed on a monitoring dashboard side-by-side with the registration picture, so that the two can be matched against each other. The developed client-server application offers administrative system used to configure gate access policies and monitor entrances with filters by access time, user and gate. Also, we propose a mobile application that allows gate registration and serves as a door unlock key. The suggested access control model reduces installation costs required, while maintaining good security. The system is fully wireless and uses cheap autonomous RFID-tags as its main component. We hope, that the proposed system architecture will find its application in small to medium-sized companies.
Highlights
Many of the modern enterprises use turnstiles or smart doors with access card scanners, where predominantly RFID cards are used
We describe a novel access control scheme, which doesn’t use card scanner and offers higher security guarantees when entering a gateway without needing video surveillance cameras
In order to avoid data rewrite by third party applications or intentional data corruption, tag programming is protected via tag programming password
Summary
RFID tags see a widespread use in modern security systems, including home intercoms, access control cards, contactless credit cards, biometric passports. We focus on a single application, namely access control systems They have either high cost or low security guarantees. The access control model that we suggest reduces installation costs required, as it is fully wireless and uses cheap autonomous RFID-tags as its main component.
