Image Forming Apparatus Local Login via Mobile Session

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users remotely logged into an image forming apparatus still need to perform a local login to directly manipulate the device, which is inconvenient.

Innovation Solution

The image forming apparatus and mobile terminal implement a method where session information is generated upon remote login, allowing the mobile terminal to request and approve local login using this session information, eliminating the need for direct local login.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If remote login is implemented allowing users to access image forming apparatus through mobile terminal, then user accessibility is improved, but additional local login step is required which increases operation complexity

Engineering Contradiction:

Improveremote accessibilityVSAvoidlogin process simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary authentication during remote login, storing authentication results and session information in advance. This preliminary action enables the apparatus to automatically recognize and authenticate the user during local login operations, eliminating the need for users to perform separate local login steps while maintaining security.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If separate local login is required after remote login, then security is maintained, but user convenience deteriorates due to multiple authentication steps

Engineering Contradiction:

Improveauthentication securityVSAvoidoperation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system introduces session information as an intermediary element that bridges remote and local login processes. This session information, generated during remote authentication, serves as a mediator that allows the apparatus to automatically verify user identity during local operations without requiring users to re-enter credentials, thus maintaining security while improving convenience.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If automatic local login is implemented using remote session information, then operation simplicity is improved, but system complexity increases due to session management requirements

Engineering Contradiction:

Improvelogin process simplicityVSAvoidsession management complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system implements self-service mechanisms where the image forming apparatus automatically manages session information without requiring complex external intervention. The apparatus autonomously generates, stores, and utilizes session information from remote login operations to facilitate automatic local authentication, reducing the need for complex session management infrastructure while maintaining operational simplicity.

Inventive Principle:

Principle #25Self-service

AI summary

Provided is a local login processing method of an image forming apparatus, the local login processing method including: generating session information according to a remote login request upon receiving the remote login request from a mobile terminal; transmitting the session information to the mobile terminal; receiving, from the mobile terminal, a local login request including local login information generated by using at least some of the session information; and approving the local login request by comparing the session information and the local login information.
