Display Capture Prevention with Integrated Recording-Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Information Handling Systems (IHSs) lack effective methods to prevent content rendered on their displays from being captured or recorded by unauthorized devices, posing risks to data privacy and security, especially in public settings or when used by unauthorized users.
Innovation Solution
Implementing a system that utilizes a webcam pipeline with Machine Learning (ML) or Artificial Intelligence (AI) models to detect suspicious devices and execute responsive actions such as disabling the display, applying privacy screens, or capturing user photographs to prevent unauthorized recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is displayed on the IHS display, then information is accessible and useful, but the content can be captured or recorded by unauthorized devices
Solution Approach 1:
The system applies preliminary anti-action by detecting the presence of unauthorized recording devices before content capture occurs. The camera captures images of the display area, and image recognition algorithms identify recording devices in advance, triggering preventive actions such as displaying warning messages, blocking the display, or alerting security personnel before unauthorized capture can happen.
Solution Approach 2:
The system introduces an intermediary monitoring layer between the display and potential recording devices. A camera positioned to monitor the display area captures images that are processed by image recognition algorithms. This intermediary system acts as a mediator that detects recording attempts and triggers appropriate responses, creating a protective barrier without interfering with normal display functionality.
2Difficulty of detecting and measuring
If a camera is integrated into the display to detect recording devices, then detection capability is improved, but device complexity increases
Solution Approach 1:
The integrated camera serves multiple functions: it acts as both a display component and a monitoring device for detecting recording attempts. The same camera hardware is used for both displaying content and capturing images of the display area, while image recognition algorithms enable the system to distinguish between normal viewing and recording attempts. This multi-functionality reduces the need for separate dedicated monitoring hardware.
Solution Approach 2:
The system uses its own integrated camera to monitor itself for recording attempts, eliminating the need for external monitoring equipment. The image recognition algorithms process images captured by the integrated camera to detect recording devices, allowing the display system to self-monitor and self-protect without requiring additional complex external systems.

AI summary
Systems and methods for preventing content rendered by an Information Handling System (IHS) display from being captured or recorded (e.g., photographed, filmed, recorded, etc.) are described. In an embodiment, an IHS may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive an image from a camera; detect a device in the image; and in response to the detection, prevent content rendered by a display from being captured or recorded by the device.
