Dual-Reader Entrant Access Control for Reliable Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reader-based methods for managing and controlling entrant access face challenges such as authentication failures due to inaccurate tagging, slow processing times, and difficulty in handling large numbers of users, especially when users fail to maintain proximity to the reader or when multiple users need to be authenticated simultaneously.
Innovation Solution
A system combining a short-range reader for primary authentication and a proximity reader for secondary authentication, where the short-range reader performs pre-verification on unique ID data and the proximity reader uses partial unique ID data for secondary authentication, reducing the need for precise tagging and enhancing processing speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional proximity reader is used for authentication, then hardware configuration is simple and security is high, but authentication fails when users do not maintain accurate tagging position and processing is slow for large numbers of users
Solution Approach 1:
The authentication process is segmented into two distinct stages: pre-authentication using a short-range reader that allows flexible positioning, and final authentication using a proximity reader that requires accurate tagging. This segmentation resolves the contradiction by allowing ease of operation in the first stage while maintaining reliability in the second stage.
Solution Approach 2:
The system performs preliminary authentication using a short-range reader before the final proximity-based authentication. This preliminary action allows users to initiate the process without precise tagging, reducing the operational difficulty, while the subsequent proximity authentication maintains security and reliability.
2Reliability
If a conventional proximity reader is used for authentication, then hardware configuration is simple, but authentication processing time increases when many users need to be authenticated simultaneously
Solution Approach 1:
The authentication workflow is divided into two phases: an initial filtering phase using a short-range reader that can handle multiple users simultaneously with relaxed positioning requirements, and a final verification phase using the proximity reader. This segmentation increases overall processing speed by reducing the bottleneck at the proximity reader while maintaining authentication reliability.
Solution Approach 2:
The system performs preliminary filtering and pre-authentication using the short-range reader before users reach the proximity reader. This preliminary action reduces the number of users that need to be processed by the proximity reader, thereby increasing overall authentication throughput while maintaining the reliability of the final authentication decision.
3Reliability
If users do not place the terminal in close proximity to the reader or do not maintain tagging state, then authentication fails in conventional systems, but the system becomes more difficult to operate
Solution Approach 1:
The authentication process is split into two stages: a lenient pre-authentication stage using a short-range reader that does not require precise positioning, and a strict final authentication stage using a proximity reader. This segmentation allows users to complete the process even if they struggle with precise tagging, as the first stage can be completed more easily, reducing time loss while maintaining overall reliability through the second stage.
