Mobile Terminal Authentication Message Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal technologies often display unnecessary authentication confirmation messages due to variations in radio wave strength, leading to unintended authentication operations when approaching an image forming device, and fail to differentiate between authentication modes set on the device.
Innovation Solution
A mobile terminal system that sets an authentication mode between a request mode requiring user authentication and a non-request mode not requiring it, using a display unit to show a confirmation message only when the authentication mode is set to the request mode, and acquiring this information from the image forming device via near field communication or wireless LAN to determine whether to display the message.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal automatically starts authentication operation in response to detection of approach to the image forming device, then the authentication operation can be performed conveniently, but the authentication operation may be performed contrary to user's intention due to excessive response
Solution Approach 1:
The system displays a confirmation message to the user before automatically performing authentication operation. The user can confirm or cancel the authentication by operating the display unit, providing feedback control to prevent unintended authentication while maintaining convenience.
2Reliability
If the confirmation message is displayed without restriction according to the approach of the mobile terminal to the image forming device, then the user intention can be confirmed, but a message unnecessary for the user may be also displayed
Solution Approach 1:
The mobile terminal acquires authentication mode information from the image forming device before displaying the confirmation message. By checking whether the device is set to authentication request mode in advance, the system avoids displaying unnecessary messages when authentication is not required, reducing information loss.
3Loss of information
If the mobile terminal displays confirmation message based on authentication mode information, then unnecessary messages can be reduced, but the device complexity increases
Solution Approach 1:
The image forming device stores and provides its own authentication mode information autonomously. The mobile terminal simply acquires this information from the device without requiring complex centralized control, allowing the system to reduce unnecessary messages while maintaining relatively simple device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces the display of unnecessary messages by accurately determining the authentication mode and only prompting the user for authentication when necessary, enhancing user intention confirmation and operational efficiency.
Implementation Method 1
a radio wave having a strength increased to a certain level is required to be circumferentially transmitted from the image forming device, because a radio wave from the image forming device has variation in strength

AI summary
A mobile terminal operated in cooperation with an information processing device capable of setting an authentication mode relating to user authentication to one mode selected from two kinds of modes of an authentication request mode requiring the user authentication, and a non-authentication request mode not requiring the user authentication, the mobile terminal including: a display unit configured to display a confirmation message inquiring a user of the mobile terminal whether to perform authentication operation; and a control unit configured to control display operation for displaying the confirmation message, acquiring, from the information processing device, authentication mode information being information representing whether the authentication mode is the authentication request mode or the non-authentication request mode, and displaying the confirmation message on the display unit, on condition that the authentication mode information is acquired, the authentication mode information representing that the authentication mode is the authentication request mode.
