Lock Interface Module for Real-Time Credential Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy access control systems face challenges in maintaining timely synchronization between lock databases and head end servers, leading to security vulnerabilities due to delays in updating credential lists, especially for remote doors accessed infrequently.
Innovation Solution
The implementation of a lock interface module that communicates with an access management system to quickly propagate changes in access permissions to electronic locks via short-range wireless communication, ensuring real-time updates and reducing the risk of unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If offline locks with onboard databases are used, then autonomy and independence from host connection are improved, but synchronization timeliness and security visibility deteriorate
Solution Approach 1:
A lock interface module is introduced as an intermediary component between the head-end server and the electronically activated locks. This module receives credential lists from the access management computer and transmits them to the locks via short-range wireless communication, enabling timely credential updates while maintaining lock autonomy. The intermediary resolves the contradiction by providing a communication bridge that allows synchronous updates without requiring constant host connection.
Solution Approach 2:
The patent replaces the traditional mechanical/wired connection system with wireless communication (Bluetooth, Wi-Fi, or other short-range wireless protocols). This substitution allows the lock interface module to communicate credential updates to locks without physical connection, maintaining autonomy while achieving real-time synchronization. The wireless medium acts as a substitute for direct mechanical coupling, resolving the timing contradiction.
2Reliability
If credential lists are updated frequently to maintain security, then security vulnerability window is reduced, but communication overhead and energy consumption increase
Solution Approach 1:
The system implements periodic credential list updates through the lock interface module, which receives updated credential lists from the access management computer at scheduled intervals or triggered by security events. This periodic action maintains security by ensuring locks have current credential information while allowing the system to enter low-power states between updates, thus managing energy consumption effectively.
Solution Approach 2:
The electronically activated locks are equipped with onboard databases that store credential lists locally. This self-service capability allows locks to independently verify credentials without requiring continuous communication with the host system. The locks can operate autonomously using stored credentials, reducing communication frequency and energy consumption, while the lock interface module periodically refreshes these stored credentials to maintain security.
