Digital Security Marks for Image Capture Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users equipped with high-resolution image and video capturing devices face challenges in preventing unauthorized capturing of confidential, private, and copyrighted visual communications, such as videos and images, which are often not detectable by human eyes but can be recognized by security programs to prevent image or video capture.
Innovation Solution
A security program embeds digital security marks within visual communications that are imperceptible to human observers but detectable by image capturing devices, preventing unauthorized image or video capture by analyzing and embedding these marks in a way that blends them with the background, using techniques like histogram analysis and color modification to ensure they are not detected by humans while being recognizable by the security software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital security marks are embedded in visual communications to prevent image capture, then image capture prevention capability is improved, but the visual communication becomes detectable by security programs rather than being completely invisible
Solution Approach 1:
The patent applies color modification techniques to embed security marks that are imperceptible to human eyes but detectable by security programs. The security marks are modified in color space (e.g., converting to grayscale or adjusting color channels) so that they blend with the background visual communication, making them invisible to humans while remaining detectable through automated analysis by security software.
Solution Approach 2:
The patent changes parameters of the visual communication such as color depth, brightness, and contrast to embed security marks. By modifying these parameters, the security marks become indistinguishable from the background to human observers while security programs can detect them through analysis of these parameter changes, thus preventing image capture while maintaining visual appearance.
2Object-affected harmful factors
If security marks are made imperceptible to humans by blending with background, then human visual detection is prevented, but the marks must be carefully designed to avoid detection while remaining detectable to security software
Solution Approach 1:
The system modifies color parameters of the visual communication to embed security marks that are imperceptible to humans. By transforming colors into ranges that are invisible to human vision (e.g., very low saturation or specific wavelength ranges), the marks blend seamlessly with the background while security programs can detect them through automated color analysis.
Solution Approach 2:
The patent uses an intermediary approach where security marks serve as a mediator between human perception and machine detection. The marks are designed to be invisible to humans (the intermediary state) while being detectable by security programs through specialized analysis, thus mediating between the conflicting requirements of human visual privacy and automated detection.
3Object-affected harmful factors
If histogram analysis and color modification techniques are used to embed security marks, then the marks become undetectable to humans, but the processing complexity increases
Solution Approach 1:
The patent applies histogram analysis to modify color parameters of the visual communication. By analyzing the color distribution histogram and adjusting parameters within specific ranges, the system embeds security marks that are imperceptible to humans while maintaining automated detectability. This parameter-based approach balances human invisibility with machine detectability.
Solution Approach 2:
The system uses color modification techniques that leverage histogram data to embed security marks in color spaces invisible to humans. By modifying colors within specific ranges identified through histogram analysis, the marks become undetectable to human vision while security programs can detect them through automated color space analysis, managing processing complexity through targeted color manipulation.
