Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing techniques for connecting remote terminals to image processing apparatuses allow unrestricted access, leading to potential leaks of document information, as anyone can acquire and transmit information about the documents set on the image processing apparatus using remote operations.

Innovation Solution

An information processing system that displays predetermined identification information on the image processing apparatus when a direct operation starts and restricts remote operations by terminals other than the one that has read this information, using one-time identification with updated authentication, ensuring only authenticated terminals can perform remote operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If remote operations are permitted without restriction, then ease of operation is improved, but information security deteriorates

Engineering Contradiction:

Improveremote operation accessibilityVSAvoidinformation leakage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary authentication by requiring terminals to read identification information displayed on the image processing apparatus before permitting remote operations. This advance verification ensures that only authorized terminals can access the system, preventing information leakage while maintaining operational convenience for legitimate users.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The identification information serves as an intermediary element between the image processing apparatus and remote terminals. This mediator enables secure authentication by allowing terminals to verify their authorization status without direct exposure to sensitive document data, thus balancing accessibility with security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If identification verification is implemented, then information security is improved, but device complexity increases

Engineering Contradiction:

Improveinformation leakage preventionVSAvoidauthentication system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The image processing apparatus automatically displays identification information and performs authentication verification without requiring external authentication servers or complex verification systems. This self-service approach enables secure remote operation control while minimizing system complexity and avoiding additional infrastructure requirements.

Inventive Principle:

Principle #25Self-service

3Reliability

If one-time identification information is used, then reliability is improved, but loss of time increases

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication process time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system changes the parameter of identification information from static to dynamic (one-time use only). Each authentication session requires a new identification code that is displayed and must be read immediately, preventing replay attacks and enhancing reliability. The brief display duration naturally limits the time window for authentication, reducing overall authentication time while maintaining high security standards.

Inventive Principle:

Principle #35Parameter changes

AI summary

An information processing system includes one or plural processors configured to: when an event of starting a direct operation for an image processing apparatus has occurred, display predetermined identification information on the image processing apparatus; and restrict remote operations for the image processing apparatus performed by terminals other than a terminal that has read the identification information.
