Operation Authentication Relay Device for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operation monitoring systems in critical infrastructure often lack effective access management mechanisms, particularly when using shared user accounts or without login functions, making it difficult to identify users, track operations, and prevent unauthorized access without modifying existing software, which is costly and challenging due to high reliability demands.
Innovation Solution
An operation authentication relay apparatus that connects between the information terminal and peripheral devices, authenticates users, and controls signal relaying based on authentication results, enabling identification of users, tracking of operations, and invalidation of unauthorized access without modifying the existing software on the information terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a shared user account is used without login function, then operation efficiency is improved, but user identification capability deteriorates
Solution Approach 1:
The patent introduces a relay device as an intermediary component between the information terminal and peripheral devices. This relay device captures operation signals from peripheral devices (keyboard, mouse, etc.) and relays them to the information terminal, while simultaneously recording operation logs that identify which user performed which operation. This allows the system to maintain shared user accounts for efficiency while the relay device provides user identification capability through logging.
2Reliability
If access management software is installed on information terminal, then security control capability is improved, but system complexity and cost deteriorate
Solution Approach 1:
The patent segments the access management function from the information terminal software into a separate hardware relay device. Instead of installing access management software on the information terminal, the relay device independently performs authentication and operation logging functions. This segmentation avoids modifying the terminal software, reducing system complexity while maintaining security control capability.
Solution Approach 2:
The relay device serves as an intermediary that intercepts and processes operation signals between the peripheral devices and the information terminal. It performs authentication checks and logs operations without requiring software installation on the terminal, thereby providing security control while avoiding the complexity of software integration and verification.
3Adaptability or versatility
If software replacement or update is performed, then access management function is improved, but verification cost and time deteriorate
Solution Approach 1:
The relay device provides access management functionality as a standalone hardware component that interfaces between peripheral devices and the information terminal. This approach eliminates the need to replace or update software on the information terminal, avoiding the time-consuming verification processes required to ensure software compatibility and system reliability.

AI summary
A relay apparatus, which is connected between an information terminal and at least one peripheral device communicatively connected to the information terminal and supplying information to the information terminal, is recognized as a peripheral device by the information terminal, and recognized as an information terminal by the peripheral device. The relay apparatus comprises authentication means for authenticating a user using the information terminal by operating the peripheral device and control means for controlling relaying of an operation signal of the peripheral device operated by the user to the information terminal, based on an authentication result of the user.
