Authentication Server Terminal Registration Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing authentication systems are vulnerable to malicious users registering multiple terminals for authentication without restrictions, leading to potential misuse of services.
Innovation Solution
An information processing system that includes a first authentication terminal, a second authentication terminal, and an authentication server, where the server registers and authenticates the terminals based on user operations, restricting registration and ensuring only registered terminals can provide authentication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminals for authentication are registered without any restriction, then the ease of operation is improved, but the reliability deteriorates due to malicious users registering multiple terminals
Solution Approach 1:
The system performs preliminary device authentication and user authentication before allowing terminal registration. The authentication server verifies the device's authentication function and the user's identity in advance, ensuring that only authenticated users can register terminals through authenticated devices, thus preventing malicious registration while maintaining ease of operation for legitimate users
2Reliability
If device authentication is required before terminal registration, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The device's built-in authentication function performs self-authentication with the authentication server without requiring external verification infrastructure. The device uses its own authentication capabilities to verify its identity and the user's identity, reducing the need for additional complex verification systems while maintaining high reliability

AI summary
An information processing system includes a first authentication terminal for authenticating a first user, a second authentication terminal for authenticating a second user, a device for authenticating the device, and an authentication server that performs authentication using a registered authentication function. The authentication server registers an authentication function of the first authentication terminal based on an operation of the first user. When authentication using the first authentication terminal is requested through the device, the authentication server authenticates the first user and registers an authentication function of the device. When registration of an authentication function of the second authentication terminal is requested through the device, the authentication server registers the authentication function when the authentication function of the device has been registered. When authentication using the second authentication terminal is requested, the authentication server authenticates the second user when the authentication function of the second authentication terminal has been registered.
