Solution Overview
Problem
Enterprise systems face challenges in preventing unauthorized screen capture activities, particularly in public environments where sensitive information is vulnerable to malicious behavior, while maintaining resource and bandwidth optimization.
Innovation Solution
A computing platform equipped with an infrared sensor detects unauthorized image capture attempts, determines the displayed content, assesses the risk level, and performs remediation tasks such as alert notifications, ceasing display, or denying access to prevent image capture, using a combination of sensor arrays and image recognition techniques.

Engineering Contradiction Analysis
1Reliability
If an infrared sensor system is deployed to detect unauthorized screen capture attempts, then security reliability is improved, but device complexity and resource consumption increase
Solution Approach 1:
The system divides the detection task into multiple specialized sensor arrays (infrared sensors, image capturing devices) positioned at different locations on the display device. Each sensor type detects specific aspects of potential screen capture attempts, and the computing platform segments the analysis by evaluating different risk factors separately before combining them into an overall risk assessment.
Solution Approach 2:
The computing platform performs multiple functions using the sensor data: it detects unauthorized capture attempts, determines displayed content, assesses risk levels, and triggers remediation tasks. The same infrared sensor system serves both as a detection mechanism and as input for content analysis, reducing the need for separate dedicated systems.
2Measurement precision
If continuous monitoring with multiple sensor arrays is implemented, then detection precision is improved, but energy consumption and resource utilization worsen
Solution Approach 1:
The system uses sensor arrays that are automatically activated based on random selection algorithms rather than continuous operation. The infrared sensors and image capturing devices are periodically activated to detect infrared signals and capture images, reducing energy consumption while maintaining detection capability through strategic sampling.
Solution Approach 2:
The computing platform automatically processes the sensor data and makes decisions about remediation tasks without requiring constant external intervention. The system self-manages the activation of sensors, analysis of detected signals, risk level determination, and triggering of appropriate remediation actions, optimizing resource usage through autonomous operation.

AI summary
Aspects of the disclosure relate to preventing unauthorized screen capture activity. A computing platform may detect, via an infrared sensor associated with a computing device, an infrared signal from a second device attempting an unauthorized image capture of contents being displayed by a display device of the computing device. Subsequently, the computing platform may determine, via the computing platform, the contents being displayed by the display device. Then, the computing platform may retrieve a record of the contents being displayed by the display device. Then, the computing platform may determine a risk level associated with the infrared signal. Subsequently, the computing platform may perform, via the computing platform and based on the risk level, a remediation task to prevent the unauthorized image capture.
