Abnormality Notification Verification in Information Processing Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack a mechanism to verify the validity of abnormality notifications received from devices, leading to potential inaccuracies in determining the reliability of such notifications and subsequent system responses.
Innovation Solution
An information processing system that includes abnormality detection units in devices to generate verified abnormality notifications with certificates and signature data, and a server to verify the notifications using importance determination and verification processes, ensuring accurate determination of abnormal states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the server receives abnormality notifications from devices without verification, then the system can respond quickly to abnormalities, but the accuracy of abnormality determination may lower due to potential unreliable notifications
Solution Approach 1:
The patent applies preliminary action by having devices generate and attach signature data and certificates to abnormality notifications before transmitting them to the server. This pre-verification preparation ensures that when the server receives the notification, the authenticity can be immediately verified without delaying the response process, thus maintaining both quick response speed and high determination accuracy.
Solution Approach 2:
The patent introduces signature data and certificates as intermediary elements between the device and the server. These intermediaries serve as trusted third-party validations that enable the server to verify the authenticity of abnormality notifications without requiring complex verification processes, thereby maintaining fast response while ensuring accurate determination.
2Measurement precision
If the server verifies each abnormality notification individually, then the accuracy of abnormality determination improves, but the processing time and system complexity increase
Solution Approach 1:
The patent applies self-service by having devices automatically generate and attach their own signature data and certificates to abnormality notifications before transmission. This self-verification preparation eliminates the need for complex server-side verification mechanisms, as the devices have already performed the necessary authentication steps, thus improving determination accuracy without significantly increasing system complexity.
3Device complexity
If devices transmit abnormality notifications without self-verification, then the device complexity is reduced, but the reliability of the notified abnormality cannot be confirmed
Solution Approach 1:
The patent introduces signature data and certificates as intermediary elements that devices attach to their abnormality notifications. These intermediaries serve as trusted verification mechanisms that devices can implement with relatively simple complexity, yet they provide strong guarantees about the reliability and authenticity of the notifications, thus resolving the contradiction between low device complexity and high notification reliability.

AI summary
An information processing system comprising a first device and a second device (101) that are communicably connected, wherein the first device (102, 103) includes: detection means (201) for detecting an abnormality, and notification means (203) for notifying the second device of an abnormality in a case where the detection means detects the abnormality; and the second device (101) includes: reception means (204) for receiving the notification of the abnormality by the notification means, acquisition means (209) for acquiring information related to the abnormality from the first device and/or an other device of the information processing system in response to the reception means receiving the notification of the abnormality, and verification means (215) for verifying validity of the notification of the abnormality based on the information acquired by the acquisition means.
