Dual Wireless Authentication Control for Address Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for authentication at transit points like railroad stations or airports face issues with unintentional leakage of address information and inefficient management of communication capacity due to unused or expired authentication credentials, leading to increased authentication times and reduced capacity for other users.
Innovation Solution
A dual wireless communication system using both wireless LAN and NFC or bar code communication, with a control unit managing both units to ensure accurate authentication by verifying address and credential information before initiating wireless LAN connection requests, and temporarily deleting unused credentials to optimize communication capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If address information is transmitted using second wireless communication scheme to enable easy identification, then connection establishment is facilitated, but unintentional leakage of address information occurs
Solution Approach 1:
The patent introduces an intermediary mechanism where the second wireless communication unit transmits address information only after receiving a valid trigger signal from the first wireless communication unit. This intermediary control structure ensures that address information is not leaked unintentionally while still facilitating connection establishment when needed, resolving the contradiction between ease of operation and security.
2Speed
If authentication credentials are retained in the system, then authentication speed is improved, but communication capacity is reduced due to unused or expired credentials occupying resources
Solution Approach 1:
The patent implements an automatic credential management mechanism that discards unused or expired authentication credentials from the storage unit. The control unit continuously monitors credential validity and removes invalid entries, thereby recovering communication capacity while maintaining fast authentication speeds for valid credentials. This resolves the contradiction between authentication speed and communication capacity.
3Reliability
If dual wireless communication units are used for authentication, then security and accuracy are improved, but device complexity increases
Solution Approach 1:
The patent merges the control logic for two different wireless communication units into a single control unit that manages both NFC and wireless LAN operations. By combining the control functions and using a unified authentication workflow that leverages both communication types, the system achieves high reliability through dual-verification while minimizing the increase in device complexity through integrated management.

AI summary
According to one embodiment, when a control unit is notified of information in at least one second signal received by one of first and second wireless communication units after the control unit provides the second wireless communication unit with a command to transmit a first signal containing first address information and before a waiting time elapses and when the at least one second signal contains second address information assigned to an authentication apparatus having received the first signal, then the control unit provides the first wireless communication unit with a command to transmit a third signal for a connection request with the second address information set in a destination address.
