Wireless Authentication Terminal for Seamless Login
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems require users to perform explicit operations such as inserting or removing media like IC cards or USB memories to log into or out of a system, or holding them up for NFC/RFID readers, which is cumbersome.
Innovation Solution
An information processing system that allows users to log in or out by entering or leaving the communication range of an information processing terminal with a reader/writer device carrying an IC card, eliminating the need for explicit operations by using wireless communication to manage authentication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication (NFC/RFID) is used to transmit authentication information, then the convenience of login/logout is improved, but the risk of unauthorized access and information leakage increases
Solution Approach 1:
The patent introduces an information processing terminal as an intermediary between the reader/writer and the authentication system. The terminal receives wireless authentication information, processes it through encryption and verification protocols, and communicates with the server. This intermediary layer adds security validation while maintaining the wireless convenience, resolving the contradiction between ease of operation and security risk.
Solution Approach 2:
The patent replaces physical media insertion/removal (mechanical system) with wireless communication (electromagnetic field system). By using NFC/RFID technology, authentication information is transmitted through electromagnetic fields without physical contact, eliminating the need for mechanical insertion while maintaining security through digital verification protocols.
2Ease of operation
If automatic connection is implemented based on proximity detection, then the user burden is reduced, but the complexity of the system increases
Solution Approach 1:
The system implements automatic connection based on proximity detection, where the reader/writer autonomously determines when to establish communication with the information processing terminal. The terminal automatically detects the reader/writer's presence, initiates connection protocols, and manages authentication without requiring user intervention. This self-service mechanism reduces user burden while the automated protocols manage the underlying system complexity.
Solution Approach 2:
The patent implements connection request standby states where the information processing terminal preliminarily prepares for connection by monitoring for reader/writer presence and pre-establishing communication parameters. This preliminary action allows automatic connection to occur smoothly when the reader/writer enters the communication range, reducing user burden while managing system complexity through pre-configured protocols.
3Reliability
If the reader/writer remains in communication range continuously, then system availability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic connection request transmission instead of continuous communication. The reader/writer transmits connection requests at predetermined intervals while remaining in communication range, allowing the information processing terminal to maintain system availability by detecting these periodic signals while both devices can enter low-power states between transmissions. This periodic action resolves the contradiction between maintaining availability and reducing power consumption.
Solution Approach 2:
The system dynamically adjusts communication states based on presence detection. When the reader/writer is detected in communication range, the terminal transitions to a connection request standby state, preparing for potential connection. When not detected, the terminal returns to a lower-power state. This dynamic state management maintains system availability when needed while minimizing power consumption during extended periods without presence, resolving the availability-power consumption contradiction.
