Web Access Credentials for Instant Electronic Lock Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic access control systems face challenges with time delays and power consumption issues due to the need for high-bandwidth communication protocols, which can render systems impractical for instantaneous access and efficient power management, especially in facilities with transient or one-time users.
Innovation Solution
The system employs a multi-channel communication approach using unidirectional and bidirectional communication channels based on the type and urgency of access control information, with unidirectional channels for authentication and bidirectional channels for voluminous data, and utilizes visible light communication to reduce power consumption and configuration time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-bandwidth communication protocols are used to exchange access control information, then communication reliability is improved, but time delay increases and power consumption increases
Solution Approach 1:
The patent segments communication into two distinct channels: a configuration channel for exchanging access control information and credentials, and an access channel for instantaneous access authentication. This segmentation allows each channel to be optimized independently - the configuration channel uses high-bandwidth protocols for reliable data exchange, while the access channel provides rapid authentication without the overhead of full communication protocols.
Solution Approach 2:
The patent introduces an intermediary device (such as a server or controller) that pre-processes and stores access credentials. During access events, the intermediary quickly verifies credentials without requiring real-time communication between all system components. This intermediary approach reduces communication time delays while maintaining security and reliability.
2Reliability
If high-bandwidth communication protocols are used to exchange access control information, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent divides communication activities into configuration phase and access phase. The high-power, high-bandwidth communication is confined to the configuration phase where credentials are exchanged. During access events, only low-power verification communications are needed, significantly reducing overall power consumption while maintaining communication reliability for critical authentication data.
Solution Approach 2:
The system uses periodic credential verification instead of continuous high-bandwidth communication. Access credentials are exchanged during configuration, then verified rapidly during access events. This periodic approach allows the system to use high-bandwidth protocols only when necessary for reliable data exchange, rather than maintaining constant high-power communication.
3Speed
If instantaneous access is implemented, then access speed is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-exchanging and storing access credentials during a configuration phase before access events occur. During instantaneous access events, the system only needs to verify pre-configured credentials rather than establishing full communication protocols in real-time. This preliminary preparation reduces access time while the added complexity is confined to the initial configuration stage.

Data Source
AI summary
Methods and systems relating to administration of access credentials for electronic access control are disclosed. Web resources are provided for rendering a webpage including an access credential. A server device receives an access instruction authorizing a user to access an electronic lock associated with the access credential. A client device of the user transmits a first request for the access credential. The first request may be generated by a browser application of the client device. The server device provides the web resources and a browser cookie to the client device. Responsive to subsequent requests for the access credential, the server device determines whether the client device is authorized to receive the access credential based on the client device providing the browser cookie. When the server device determines that a subsequent request authorizes the client device to receive the access credential, the web resources are provided to the browser application.
