Biometric Lockset Enrollment via Light Codes and Mobile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric locksets face challenges in efficiently managing and tracking user status, particularly when biometric sensors are used, as administrative users find it difficult to easily enroll and manage authorized and unauthorized users.
Innovation Solution
A biometric lockset system that includes a processor, memory, light communication unit, wireless communication interface, and fingerprint sensor, which uses light codes to guide users through the enrollment process, transmitting messages to a mobile device to display enrollment status, allowing for easy user identity association with fingerprint data and management of user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric sensors are used to identify users, then user authentication security is improved, but the ease of managing and tracking user status deteriorates
Solution Approach 1:
The patent introduces an intermediary mobile device application that acts as a mediator between the lockset controller and the administrative user. This intermediary system receives user status information from the lockset, processes it, and presents it in an organized manner to the administrative user through a user interface, thereby improving ease of operation without compromising the biometric authentication security maintained within the lockset controller
Solution Approach 2:
The system implements feedback mechanisms where the lockset controller continuously monitors user status (such as enrollment completion, access history, and account state) and transmits this information to the mobile device. The administrative user receives real-time feedback about user status through the application, enabling easy tracking and management while the lockset maintains secure biometric authentication operations
2Adaptability or versatility
If multiple users are enrolled in the system, then user access flexibility is improved, but the complexity of tracking and managing user status increases
Solution Approach 1:
The patent segments the user management function by creating separate user profiles and status tracking for each user in the system. Each user has an independent entry in the memory with their specific biometric data, access permissions, and status information. The mobile device application then manages these segmented user records individually, allowing flexible multi-user access while simplifying tracking through organized, separate data structures rather than a monolithic complex system
Solution Approach 2:
The mobile device application serves multiple functions: it displays user status information, manages user enrollment, tracks access history, and communicates with the lockset controller. This multi-functional application consolidates what would otherwise be multiple separate tracking and management systems into a single universal interface, reducing overall system complexity while maintaining flexible multi-user access capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables seamless user enrollment and management, providing administrative users with real-time enrollment status updates, ensuring secure and efficient tracking of authorized users and their access privileges.
Implementation Method 1
A first light code is displayed, which indicates an initial state of fingerprint data capture
Implementation Method 2
a biometric sensor (e.g., a fingerprint sensor) configured to receive a fingerprint from a user
Implementation Method 3
A first message is transmitted by a wireless communication protocol to the mobile device
Data Source
AI summary
A method of enrolling a user at a biometric lockset is described. The method includes receiving user access information from a mobile device of an administrative user of the biometric lockset. The user access information indicates to the biometric lockset to enter an enrollment mode in which a user identity is associated with fingerprint data in a user entry within a memory of the biometric lockset. A plurality of different light codes are displayed on the lockset, each one of the plurality of light codes representative of a different state of fingerprint data capture. A message is transmitted to the mobile device, and corresponds to the light code displayed at the lockset. The completed fingerprint data is stored in association with the user identity of the user in the user entry.
