Secure Confidential Data Visualization via Masked Display Toggle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for setting system settings of image forming devices using external devices like PCs do not adequately secure the display of confidential data, such as passwords, during communication, as they either reveal sensitive information or fail to confirm input data post-setting due to insecure communication paths.
Innovation Solution
An information processing device with a communication device, display device, and controller that generates a masked display for confidential data, displays a button to toggle visibility only when the communication path is secure, allowing users to securely visualize and confirm input data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If confidential data is displayed in a masked display to prevent observation by third parties, then security is improved, but the user cannot confirm which characters have been input
Solution Approach 1:
The system performs preliminary verification of communication path security before enabling the visualization function. The controller determines whether the communication path is secure in advance, and only then allows the masked display to be removed for user confirmation. This preliminary security check ensures that confidential data is only visualized when transmission security is guaranteed.
2Loss of information
If confidential data is transmitted to a terminal device for visualization, then the user can confirm input data, but the data may be intercepted or leaked during communication
Solution Approach 1:
The controller acts as an intermediary that mediates between the terminal device and the confidential data transmission. It determines whether the communication path is secure and based on this determination, controls whether confidential data is transmitted to the terminal device for visualization. This intermediary function prevents direct transmission of confidential data over insecure channels.
3Ease of operation
If a display button is always provided to remove masked display, then user convenience is improved, but confidential data may be exposed when communication path is insecure
Solution Approach 1:
The display button is dynamically provided or not provided based on the security status of the communication path. When the communication path is determined to be secure, the display button is provided to allow users to remove the masked display. When the communication path is insecure, the display button is not provided, preventing potential data exposure while maintaining user convenience when safe.

AI summary
The present invention includes a receiver capable of receiving confidential data, a screen display controller that performs a control that displays a screen in which the confidential data received by the receiver is in a masked display, a determiner that determines whether or not an identification display for visualizing the confidential data in the masked display is to be displayed, and an identification display controller that performs a control that displays the identification display on the screen when it is determined by the determiner that the identification display is to be displayed.
