Facial Authentication Lock Control for Secure Guest Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic locks face challenges in managing image data captured by video cameras and ensuring secure facial authentication processes, particularly in controlling access for guest users and maintaining data security.
Innovation Solution
An electronic lock with integrated facial authentication features, including a camera and control circuit, allows for secure enrollment and actuation using facial recognition, with a server managing user profiles and ensuring data security through wireless communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial authentication features are integrated into the electronic lock, then access control security is improved, but device complexity increases
Solution Approach 1:
The patent combines the facial authentication circuit (including camera and processing components) with the electronic lock body into a single integrated device. This merging approach enables secure facial-based access control while consolidating multiple functions (authentication, locking, and control) into one unified system, thereby improving security without proportionally increasing overall system complexity.
2Measurement precision
If image data is captured by video cameras for authentication, then authentication accuracy is improved, but data security management becomes more difficult
Solution Approach 1:
The patent extracts and processes only the essential facial authentication data needed for verification, rather than storing or managing all captured image data. The facial authentication circuit processes biometric information locally to generate authentication signals, eliminating the need to manage large volumes of raw image data while maintaining high authentication accuracy through specialized biometric processing.

AI summary
An electronic lock includes an interior subassembly including a manual turnpiece, a control circuit, and a motor actuatable by the control circuit, and an exterior subassembly including a facial authentication circuit operatively connected to the control circuit. The electronic lock includes a latch operatively connected to the interior subassembly, the latch being engageable by the manual turnpiece or the motor to move the electronic lock between a locked state and an unlocked state. The facial authentication circuit includes at least one camera and is configured to generate an authentication signal to the control circuit, and wherein, at least in part in response to the authentication signal, the control circuit is configured to actuate the motor to move the electronic lock between the locked state and the unlocked state.
