Screen Content Display Using Facial Verification and Capture Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying digital content on electronic devices fail to prevent unauthorized saving or access by unintended users, as they either disable all screenshot and video capture functions or rely on detecting multiple viewers without ensuring the content is not stored on the device.
Innovation Solution
A method using facial recognition and biometric data to authenticate authorized users, encrypting content, and disabling screenshot and video capture functions when unauthorized access is detected, ensuring content is only displayed to intended recipients and not stored locally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screenshot and video capture functions are disabled on the device, then content cannot be saved through these functions, but users can still photograph or video the screen by other means
Solution Approach 1:
The system preemptively detects the presence of external recording devices (cameras, smartphones) before content is displayed or during display, and prevents content from being shown at all when unauthorized recording devices are detected. This preliminary anti-action eliminates the possibility of screenshotting or screen photography entirely, making the content protection more reliable than simply disabling capture functions.
2Reliability
If facial recognition and continuous monitoring are implemented to verify authorized users, then content security is improved, but device complexity and processing requirements increase
Solution Approach 1:
The system uses the device's existing camera and sensor components to perform self-verification of the user's identity and presence. The camera captures images for facial recognition, and sensors detect the presence of external recording devices. This self-service approach leverages existing hardware capabilities rather than requiring complex additional verification systems, thereby reducing overall device complexity while maintaining strong security.
3Reliability
If the content is displayed only when an authorized user is detected, then unauthorized access is prevented, but the content cannot be accessed when no user is present or an unauthorized user is detected
Solution Approach 1:
The system continuously monitors the viewing environment using cameras and sensors, providing real-time feedback about user presence and authorization status. Based on this feedback, the system dynamically adjusts content display - showing content only when authorized users are present and no unauthorized recording devices are detected. This feedback mechanism ensures both security and appropriate accessibility without manual intervention.
Data Source
AI summary
The invention provides a computer implemented method of receiving content at an electronic processing device. The electronic processing device has a data processing application. The method comprises a first step of receiving a message or invitation, said message or invitation not including the content to be received, wherein opening of the message or invitation causes the data processing application to configure a camera of the electronic processing device to capture image data. The data processing application uses image data captured by said camera of said electronic processing device to determine that a user viewing said screen is an authorized or recognized user and, in response to a positive determination, receives said content as encrypted content at said data processing application. In response to a negative determination, the content is not received said content at said data processing application. The data processing application is also configured to not locally store said provided content on said electronic processing device and to disable any screen or video capture functionalities of the electronic processing device.
