Biometric Face Vector Pairing for Secure Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device pairing methods, particularly for portable devices, face challenges in ensuring secure data sharing without requiring users to remember multiple passwords, and existing solutions may not function when remote servers are unavailable.
Innovation Solution
The use of biometric face vectors, determined from images captured by electronic devices, for authentication purposes, allowing devices to pair securely without the need for password memorization and enabling pairing even without cellular network reception by comparing and sharing these vectors directly between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pairing methods are used, then devices can establish communication channels, but users must remember and manage multiple passwords which increases complexity and reduces ease of operation
Solution Approach 1:
The system uses the camera and image processing capabilities already present in the electronic devices to automatically capture and process facial images for authentication. The devices perform pairing authentication autonomously by comparing biometric face vectors without requiring user intervention for password entry or management, making the pairing process self-service and user-friendly
Solution Approach 2:
The patent replaces the mechanical/password-based authentication system with a biometric authentication system using facial recognition. Instead of requiring users to memorize and enter passwords, the system uses image capture and biometric comparison to establish pairing, substituting the traditional mechanical authentication mechanism with an automated biometric one
2Reliability
If pairing authentication is performed, then security is improved, but the process requires reliance on remote servers which reduces reliability when servers are unavailable
Solution Approach 1:
The patent extracts the pairing authentication functionality from the remote server and implements it directly within the electronic devices. Each device captures its own facial image, processes it to generate a biometric face vector, and performs the authentication comparison locally, eliminating the mandatory dependency on remote servers for pairing authentication
Solution Approach 2:
The system uses biometric face vectors as an intermediary data format that enables direct peer-to-peer authentication between devices. Instead of requiring direct server mediation, the face vectors serve as a shared authentication medium that allows devices to verify each other's identity independently, improving adaptability to network conditions
3Reliability
If biometric data is transmitted between devices, then authentication security is enhanced, but data transmission requirements increase
Solution Approach 1:
The system creates a simplified copy of the facial biometric data in the form of a biometric face vector, which captures the essential authentication information while discarding unnecessary image details. This compressed representation is then transmitted between devices for authentication comparison, reducing data transmission volume while maintaining security
Solution Approach 2:
The patent transforms the raw facial image data into a parameterized biometric face vector format. By changing the data representation from pixel-based images to feature-based vectors, the system reduces the quantity of data that needs to be transmitted while preserving the essential authentication parameters needed for security
