Screen Content Frame Segmentation for Personal Information Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing problem of personal information leakage through electronic devices, including unauthorized sharing and shoulder surfing attacks, necessitates a method to protect sensitive content displayed on screens.
Innovation Solution
An electronic device and method that modifies content by identifying its type and copying it into frames, applying personalized protection modes such as pixel-level modifications or frame insertions, and displaying merged content as a video to prevent unauthorized duplication or sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is displayed normally on the screen, then user experience and content accessibility are improved, but personal information leakage and unauthorized sharing increase
Solution Approach 1:
The content is divided into multiple frames that are displayed sequentially to form a video. Each frame contains a portion of the original content, and when captured or recorded, the fragmented frames cannot be easily reassembled to reveal the complete information, thus preventing unauthorized sharing while maintaining normal display functionality.
Solution Approach 2:
The static content is transformed into a dynamic video format by distributing content across multiple frames displayed in sequence. This dimensional transformation from static to dynamic display enables the content to appear normal during viewing but becomes difficult to capture or record完整地 when converted to video format.
2Reliability
If watermark or screen shot disabling functions are implemented, then personal information protection is improved, but device complexity and user convenience deteriorate
Solution Approach 1:
The system automatically identifies sensitive content and applies frame segmentation without requiring user intervention or complex configuration. The protection mechanism operates transparently in the background, converting content to framed video format automatically, thus providing robust protection while maintaining simple operation and avoiding additional device complexity.
3Reliability
If content is transformed into framed video format, then unauthorized sharing prevention is improved, but content recognition and searchability worsen
Solution Approach 1:
The system performs preliminary processing by embedding identifiable characteristics or metadata within the framed video structure before display. This allows the content to maintain searchability and recognizability through automated systems while the frame segmentation prevents manual capture and unauthorized sharing, thus resolving the contradiction between protection and information accessibility.

AI summary
An electronic device is provided. The electronic device includes a display and at least one processor operatively coupled to the display. The at least one processor may be configured to, when displaying content on the display, execute a personal information protection mode, identify a type of the content displayed on the display, copy the content into a plurality of frames, modify each of at least some of the plurality of frames based on the identified type of the content, and display a video obtained by merging the plurality of frames including the at least some modified frames on the display.
