Display Apparatus Handwritten Data Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses struggle to effectively manage and conceal confidential information displayed through handwritten input, particularly in multi-user environments where personal information may be inadvertently exposed to third parties.
Innovation Solution
A display apparatus equipped with processing circuitry and memory that converts handwritten data into a character string and conceals this character string after a predetermined time has elapsed since its initial display, using a mask display method to protect sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handwritten data is displayed as a character string for user confirmation, then information usability is improved, but confidential information may be exposed to third parties
Solution Approach 1:
The system performs preliminary conversion of handwritten data to character strings and displays them temporarily for user confirmation. This preliminary action allows users to verify information accuracy before final storage, while the temporary nature of display limits exposure time. The conversion and display are performed in advance of any permanent recording or sharing operation.
Solution Approach 2:
The display state of character strings is made dynamic through automatic timing control. The system automatically transitions the display from a visible state to a concealed state after a predetermined time period elapses. This dynamic state change ensures that confidential information is only visible when necessary for user confirmation, then automatically hidden to prevent exposure to third parties.
2Object-affected harmful factors
If confidential information is concealed immediately after display, then information protection is improved, but user confirmation capability deteriorates
Solution Approach 1:
The system implements periodic display of confidential information at predetermined time intervals. Rather than continuous display or immediate concealment, the information is displayed periodically for user confirmation, then concealed. This periodic action pattern balances protection needs with usability, allowing users sufficient opportunity to verify information while limiting overall exposure time.
Solution Approach 2:
The system provides preliminary display of character strings before final processing or storage. This preliminary display phase allows users to confirm information accuracy before it is permanently recorded or transmitted. The timing is controlled to provide adequate confirmation opportunity while ensuring eventual concealment for protection.
3Measurement precision
If handwritten data is converted to character string and displayed continuously, then information accuracy is improved, but information exposure time increases
Solution Approach 1:
The conversion of handwritten data to character strings is performed as a preliminary action with temporary display for verification. The system converts and displays the character string briefly to allow accuracy verification, then automatically conceals it. This preliminary conversion and display approach ensures information accuracy through user confirmation while minimizing the duration of exposure.
Solution Approach 2:
The display duration of converted character strings is made dynamic and time-limited. The system automatically controls the display state to transition from visible to concealed after a predetermined time period. This dynamic time control ensures that information remains visible long enough for accuracy verification but is automatically hidden afterward to minimize exposure time.

AI summary
A display apparatus displays handwritten data that is input with an inputter. The display apparatus includes processing circuitry; and a memory storing computer-executable instructions that cause the processing circuitry to convert the handwritten data into a character string; and conceal the character string generated by converting the handwritten data, in response to determining that a first time has elapsed after the character string is displayed.
