Proxy Authentication Terminal for Wide-Area Line Faults
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems face disruptions when a fault occurs in the wide-area line, leading to the inability of the authentication server to issue authentication codes, causing interruptions in job processing and requiring expensive servers for proxy authentication.
Innovation Solution
An information processing system that includes an authentication server, a proxy authentication terminal, and an information processing device, where the proxy authentication terminal performs proxy authentication using a proxy authentication privilege to issue a proxy authentication code, allowing the information processing device to instruct job processing even when the wide-area line is faulty, utilizing existing terminals like personal computers for proxy authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the authentication server is used to issue authentication codes, then authentication security is maintained, but job processing is interrupted when the wide-area line fails
Solution Approach 1:
The patent introduces a proxy authentication terminal as an intermediary device that operates within the local-area network. This terminal holds proxy authentication privileges and can issue proxy authentication codes when the authentication server is inaccessible, thereby mediating between the need for security and the need for continuous operation during wide-area line failures
Solution Approach 2:
The proxy authentication terminal is pre-configured with proxy authentication privileges and decryption keys before the wide-area line failure occurs. This preliminary preparation enables the terminal to immediately perform proxy authentication and issue codes without requiring real-time communication with the authentication server, ensuring continuous job processing
2Productivity
If a proxy authentication server is deployed to ensure continuous operation, then job processing continuity is maintained, but device cost increases
Solution Approach 1:
The patent makes an existing terminal device perform multiple functions: it serves as both a regular terminal for normal operations and as a proxy authentication terminal when needed. This multi-functionality eliminates the need for dedicated expensive proxy authentication hardware, reducing overall system cost while maintaining job processing continuity
Solution Approach 2:
The proxy authentication terminal possesses a copy of the authentication privileges and decryption keys, allowing it to replicate the authentication server's functionality locally. This copying approach enables continuous operation without requiring an additional full-featured authentication server, thereby reducing device complexity and cost

AI summary
An information processing system includes an authentication server, a proxy authentication terminal, and an information processing device. The authentication server is connected to a wide-area line located outside a prescribed area, has an authentication privilege, and issues an authentication code. The proxy authentication terminal is connected to the authentication server through the wide-area line, has a proxy authentication privilege which serves as a proxy for the authentication privilege, and issues a proxy authentication code. The information processing device is connected to the proxy authentication terminal through a local-area line located within the prescribed area, receives the proxy authentication code from the proxy authentication terminal, and instructs processing of a job.
