Image Redaction via Signal Interception and Content Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively identify and redact confidential or sensitive information in images before they are displayed on a display device, leading to potential security breaches and unintended sharing of private content.
Innovation Solution
A method that intercepts the image signal before display, analyzes it using a content recognition algorithm, and modifies it based on a ruleset to redact identified sensitive information, ensuring that only non-confidential content is displayed, even if the user attempts to show sensitive information intentionally or unintentionally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image signals are intercepted and analyzed before display, then security against unauthorized information display is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that intercepts image signals between the source and display device. This intermediary contains a content recognition algorithm that analyzes the image data and identifies sensitive information before display, effectively mediating between the raw signal and final output to enforce security policies without modifying the original display device's core functionality.
Solution Approach 2:
The patent applies preliminary action by performing content analysis and redaction decisions before the image is actually displayed. The system pre-processes the image signal, identifies sensitive content using recognition algorithms, and applies appropriate redaction measures in advance, ensuring that only sanitized content reaches the display device, thereby preventing security breaches before they can occur.
2Measurement precision
If content recognition algorithms are used to identify sensitive information, then rediction accuracy is improved, but processing time increases
Solution Approach 1:
The patent implements partial action by applying content recognition algorithms selectively rather than to all image data uniformly. The system identifies specific regions or elements that contain sensitive information and applies redaction only to those portions, rather than processing or redacting the entire image, thereby reducing overall processing time while maintaining high accuracy for the critical sensitive content.
3Reliability
If redaction is performed at the display device level rather than application level, then security effectiveness is improved, but implementation complexity increases
Solution Approach 1:
The patent applies universality by designing a display device with integrated content recognition and redaction capabilities that can handle multiple types of sensitive information (personal data, confidential business information, protected content) through a single unified system. This multi-functional approach allows the device to enforce security policies across various applications and content types without requiring separate implementation for each case, reducing overall implementation complexity.

AI summary
A system may be used to redact an image to be displayed by a display device. By intercepting a signal before an image of the signal is displayed on a display device, the display of confidential, sensitive and inappropriate information may be suppressed. More specifically, the image of the signal is analyzed using a content recognition algorithm to identify items of content, which may be redacted by modifying the signal. Using this concept, the image may be redacted by the display device, or by a port or adapter between a signal generator and the display device, without relying on redaction software local to the signal generation system.
