Physical Access Authentication Using Face Recognition and BLE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical access control systems relying on 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, which compromises security.
Innovation Solution
A PAC system integrating facial recognition software and mobile phone-based verification using Bluetooth Low Energy handshakes for two-factor authentication, requiring both the person's biometrics and login credentials to grant access, thereby ensuring the actual person's presence and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID keycard readers are used for access control, then ease of operation is improved, but security is worsened due to inability to verify the authorized person holding the keycard
Solution Approach 1:
The patent combines facial recognition technology with RFID keycard verification into a unified access control system. The facial recognition component captures and verifies the user's biometric data, while the RFID reader simultaneously validates the keycard. Both verification methods must succeed for access to be granted, merging two independent authentication mechanisms into a single integrated system that addresses the security weakness of RFID alone.
Solution Approach 2:
The system introduces a control device as an intermediary between the user and the door lock. This control device receives verification results from both the facial recognition device and the RFID keycard reader, processes the authentication logic, and only activates the door lock when both authentications succeed. The intermediary coordinates the dual-factor authentication process and prevents unauthorized access even if one factor is compromised.
2Ease of manufacture
If RFID keycards are used for access control, then ease of manufacture is improved, but security is worsened due to ease of keycard cloning
Solution Approach 1:
The system merges biometric authentication (facial recognition) with RFID keycard verification to create a dual-factor authentication system. While RFID keycards remain easy to manufacture and distribute, the addition of facial recognition provides a non-clonable authentication layer. Even if a keycard is cloned, the cloned card cannot bypass the facial recognition verification, thereby maintaining security while preserving the ease of keycard deployment.
Solution Approach 2:
The access control system uses a composite authentication approach, combining two different authentication modalities (biometric and RFID) into a single security mechanism. This composite system leverages the simplicity of RFID keycards while adding the security properties of biometric verification, creating a system that is both easy to manufacture and resistant to cloning attacks.
3Reliability
If facial recognition and mobile device verification are both required, then security is improved, but device complexity is worsened
Solution Approach 1:
The access control system is segmented into three independent functional modules: a facial recognition device, a mobile device with authentication app, and an RFID keycard reader. Each module performs a specific authentication function and communicates results to a central control device. This segmentation allows each component to be optimized independently while maintaining overall system security through coordinated operation.
Solution Approach 2:
The mobile device authentication app performs self-service by automatically generating cryptographic proofs and verifying authentication status without requiring manual user intervention. The facial recognition device independently captures and verifies biometric data, and the RFID reader autonomously validates keycards. Each component operates autonomously and contributes to the overall authentication decision, reducing the complexity burden on any single device.

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.
