Server-Mediated Electronic Apparatus Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems face security issues due to direct access from external devices, allowing unauthorized or malicious users to control and acquire status information of electronic apparatuses connected to the Internet.
Innovation Solution
An information processing system that includes an electronic apparatus, a server, and an external apparatus, where the electronic apparatus acquires and controls operation information, and the server updates and manages this information via a secure intermediary, preventing direct access by external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct access from external apparatus to electronic apparatus is implemented, then remote operation and status acquisition convenience is improved, but security vulnerability increases allowing unauthorized access
Solution Approach 1:
The patent introduces a server as an intermediary between the external apparatus and electronic apparatus. The server receives operation information from the external apparatus, stores it in an operation information control table, and then transmits it to the electronic apparatus. This mediator architecture enables remote operation convenience while preventing direct access security vulnerabilities, as the server acts as a trusted gateway that validates and controls all communications.
2Object-affected harmful factors
If a server intermediary is introduced to enhance security, then security against unauthorized access is improved, but system complexity increases
Solution Approach 1:
The patent segments the system into three distinct functional modules: the electronic apparatus (to be controlled), the external apparatus (controlling device), and the server (intermediary). The server itself is segmented into specific functional components including an operation information receiver, operation information control table storage, and operation information transmitter. This segmentation allows each component to have a clear, simple function while collectively providing secure remote operation capability.
3Reliability
If operation information is stored and managed on the server, then access control precision is improved, but information storage requirements increase
Solution Approach 1:
The server stores operation information in a control table that includes only the essential fields needed for access control: external apparatus identifier, electronic apparatus identifier, and operation information. This partial storage approach stores only the minimum necessary data to enable precise access control and operation routing, avoiding excessive storage of redundant information while maintaining reliable control precision.

AI summary
An information processing system includes an electronic apparatus, a server, and an external apparatus. The electronic apparatus acquires operation information for the electronic apparatus from the server, and directs the electronic apparatus to operate according to the operation information. The server receives an external apparatus identifier, electronic apparatus identifier, and operation information, from the external apparatus, and accumulates the information. The external apparatus accepts input of the electronic apparatus identifier and the operation information, and transmits the external apparatus identifier and the operation information to the server. Such an information processing system enables operation information for an electronic apparatus to be set and acquired, without directly accessing an electronic apparatus from an external apparatus, improving security.
