Dynamic Shielding Layer for Mobile Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying information content on mobile devices and computers lack effective privacy protection, as content is easily visible to others in public, compromising security.
Innovation Solution
A computing device generates a shielding layer for information content based on predefined privacy conditions, rendering it invisible and allowing users to hide or reveal the content through specific instructions, with mechanisms such as passcode entry or sliding gestures, and automatically restoring the shielding layer after a predefined period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information content is displayed directly on the display area, then visibility and accessibility are improved, but privacy security deteriorates
Solution Approach 1:
A shielding layer is introduced as an intermediary element between the user and the information content. This shielding layer can be selectively applied to obscure sensitive content while allowing non-sensitive content to remain visible, thus mediating between the need for visibility and the need for privacy protection.
Solution Approach 2:
The shielding layer is designed to be dynamic rather than static. It can be automatically applied or removed based on detected environmental conditions (such as presence of other people), and can also be manually controlled by the user. This dynamic behavior allows the system to adapt to different situations, providing visibility when needed and privacy when required.
2Object-affected harmful factors
If a shielding layer is always displayed over information content, then privacy protection is improved, but accessibility and usability deteriorate
Solution Approach 1:
The shielding layer is applied periodically or conditionally rather than continuously. The system automatically detects environmental conditions and applies the shielding layer only when privacy protection is needed (e.g., when other people are detected nearby). When the user is alone or in a private setting, the shielding layer is removed to restore full accessibility.
Solution Approach 2:
The system provides self-service by automatically managing the shielding layer based on environmental conditions without requiring constant user intervention. The privacy protection mechanism monitors the environment and autonomously applies or removes the shielding layer, reducing the burden on the user while maintaining both privacy and accessibility as needed.
3Adaptability or versatility
If manual control of shielding layer is required, then user control over privacy is improved, but operational complexity increases
Solution Approach 1:
The system introduces an intermediary environmental sensor that detects the presence of other people and automatically triggers the shielding layer application. This intermediary component handles the complexity of decision-making, allowing the user to simply interact with straightforward gestures (like waving hand) without needing to understand or manage complex control logic.

AI summary
A computing device receives information content, which is rendered in a predefined display area of the display. When the information content satisfies predefined conditions privacy requirement), the computing device generates a shielding layer for the information content before rendering the shielding layer and displays the shielding layer on top of the display area such that the information content becomes invisible. Subsequently, the computing device receives a shielding layer hiding instruction from a user of the computing device. In response to the shielding layer hiding instruction, the computing device hides the shielding layer from the display area and restores the shielding layer on top of the display area after a predefined hiding period in accordance with a shielding layer hiding mechanism.
