Biometric Door Access Control With Presentation Attack Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door access control systems rely on a single authentication factor, making them vulnerable to unauthorized access if the access key is obtained by an individual.
Innovation Solution
A multi-factor authentication system using a biometric-based electro-mechanical device that evaluates multiple authentication factors, including biometric, physical, and memory-based factors, with presentation attack detection, to determine the authenticity of the individual attempting access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single authentication factor (access key) is used for door access control, then the system is simple and easy to operate, but the security level is low and vulnerable to unauthorized access
Solution Approach 1:
The authentication system is segmented into multiple independent factors: biometric authentication (face, fingerprint, iris), physical item authentication (access card, mobile device), and knowledge-based authentication (PIN, password). Each factor is processed by separate modules within the reading device, and all must be satisfied for access approval, thereby enhancing security while maintaining manageable system complexity through modular design
2Reliability
If multiple authentication factors are required, then the security level improves, but the operation becomes more complex and time-consuming
Solution Approach 1:
User profiles containing multiple authentication factors (biometric data, access card credentials, PIN codes) are pre-configured and stored in the system database before access attempts. When a user approaches the door, the system automatically retrieves their profile and presents the appropriate authentication sequence, eliminating the need for users to manually select or switch between different authentication methods and streamlining the access process
3Reliability
If traditional access key systems are used, then the system is easy to implement, but it cannot detect presentation attacks (photos, videos, masks)
Solution Approach 1:
A presentation attack detection (PAD) module is introduced as an intermediary component between the biometric sensor and the authentication decision logic. This PAD module analyzes biometric data for signs of spoofing (such as detecting whether a face image is from a photo, video, or mask) before the data is used for authentication, providing an additional layer of verification that blocks fraudulent access attempts while maintaining the existing biometric authentication framework
Data Source
AI summary
A multi-factor authentication access control system is described for permitting access to secured locations. Types of authentication factors include property or physical-based items and biometric-based information. Optionally, the biometric information presented by the person is evaluated for being a presentation attack. Exemplary embodiments are directed to controlling door access.
