Physical Access Authentication Using Face and Mobile Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical access control systems using RFID keycards are vulnerable to unauthorized access due to the inability to verify the authorized person holding the keycard and the ease of keycard cloning, leading to security breaches.
Innovation Solution
A PAC system integrating facial recognition and mobile phone-based verification using Bluetooth Low Energy handshakes for two-factor authentication, which requires both the person's biometric verification and secure mobile device credentials to grant access to secure areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID keycard systems are used for physical access control, then ease of operation is improved, but security reliability deteriorates due to inability to verify authorized person and vulnerability to cloning
Solution Approach 1:
The patent combines facial recognition technology with RFID keycard systems to create a multi-factor authentication system. The access control system now requires both biometric verification (facial recognition) and electronic credential verification (RFID card validation) to grant access, merging two different authentication methods into a unified system that maintains ease of operation while dramatically improving security reliability
Solution Approach 2:
The system introduces an intermediary verification layer between the user and the secured resource. Instead of directly accepting RFID cards as sufficient proof of authorization, the system adds facial recognition as an intermediary step that verifies the identity of the card holder, preventing unauthorized access even if the card is stolen or cloned
2Reliability
If facial recognition alone is used for access control, then security reliability is improved by verifying authorized person, but device complexity increases
Solution Approach 1:
The access control system is designed to perform multiple functions: it can operate in RFID-only mode, facial recognition-only mode, or combined mode depending on the configuration and security requirements. This multi-functionality allows the system to adapt to different security needs without requiring completely separate systems, managing complexity through flexible, universal design
3Reliability
If two-factor authentication is implemented, then security reliability is improved, but ease of operation deteriorates due to additional verification steps
Solution Approach 1:
The system performs preliminary action by having users register their facial biometrics in advance during system setup. This preliminary enrollment creates a stored biometric template that enables rapid, automatic verification during actual access attempts. The complex two-factor authentication process becomes seamless during operation because the heavy lifting of biometric processing was already done during initial registration

AI summary
A physical access control (PAC) system configured to perform a two-factor authentication prior to granting access to a secure area. The PAC system includes an access point device configured to perform facial recognition on a person proximate to the access point device, and perform wireless handshake with a mobile device associated with the person prior to granting or denying entry to the secure area.
