Touch Panel Password Input via Linked User Terminal Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conferences where a password is set for a file displayed on a touch panel, there is a risk of the password leaking to other participants due to direct input on the display.
Innovation Solution
A system that uses a user terminal to input information, such as a password, which is then reflected on the touch panel display without exposing the input on the display to others, using a two-dimensional code to link the input fields between the terminal and the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user inputs a password directly on the touch panel display during a conference, then the password can be entered into the input field, but the password may leak to other conference participants who can see the display
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture the input field and overlay masked characters. Instead of directly displaying the password input on the touch panel, the system uses the camera feed as a mediator to show obscured versions of the input, preventing other participants from seeing the actual password while still allowing the user to see what they are typing.
Solution Approach 2:
The patent applies visual masking by changing the appearance of the input field content. The captured input field is processed to overlay masked characters (such as dots or blurred regions) over the sensitive information areas, effectively changing the visual properties of the displayed text to hide the password from view while maintaining usability for the authenticated user.
2Measurement precision
If the password is displayed on the touch panel for the user to see what they are typing, then the user can input the password accurately, but other participants can also see the password
Solution Approach 1:
The camera serves as an intermediary that captures the input field and processes it to create a masked version for display. This mediator allows the user to see their input for accurate typing while simultaneously obscuring the sensitive information from other participants' view.
Solution Approach 2:
The system applies visual masking techniques to the captured input field, changing the appearance of the password characters through overlays such as dots, blurs, or other obscuring patterns. This maintains the visibility needed for accurate input while preventing unauthorized viewing by other participants.
3Ease of operation
If the software keyboard is displayed on the touch panel for the user to operate, then the password can be input using the keyboard, but the input process takes time and may be observed by others
Solution Approach 1:
The camera-based masking system acts as an intermediary that processes the keyboard input area in real-time, allowing the user to see their input as they type while preventing others from observing. This maintains the interactive keyboard input process without adding significant time overhead.
Solution Approach 2:
The visual masking is applied dynamically to the keyboard input area, changing the appearance of typed characters to obscured versions. This allows the user to see their input for accurate typing while preventing observation by others, maintaining both convenience and security.

AI summary
An information processing system includes a display controller that causes a display device to display a first input field in which predetermined information can be input, and an input information acquirer that acquires the predetermined information input by a user terminal when the user terminal becomes communicable. The display controller displays the predetermined information acquired by the input information acquirer in the first input field.
