Secure Information Streaming via Continuous Request Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The unauthorized interception and copying of sensitive information, particularly in semi-public settings, remains a significant concern due to the vulnerability of decrypted information on computer screens and the lack of effective protection against unauthorized access to both displayed and stored data.
Innovation Solution
A system utilizing a controlling server and a controlled server communicates via a socket channel to provide secured streaming of information, authenticating user devices and restricting input/output operations to prevent copying or recording, ensuring that information is displayed in a continuous, encrypted format only through a designated I/O component, preventing unauthorized access and copying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is displayed on a computer screen for viewing, then the intended recipient can view the information, but the information becomes vulnerable to unauthorized interception and copying
Solution Approach 1:
The system dynamically controls the display of information based on detected viewing conditions. When unauthorized viewing is detected (e.g., multiple monitors, screenshot attempts, unusual viewing angles), the system automatically obscures or terminates the display, making the information dynamically protected rather than statically vulnerable
Solution Approach 2:
The system continuously monitors viewing conditions and provides feedback to adjust security measures. Sensors detect environmental factors and user behavior, and the system responds by modifying display parameters or initiating security protocols, creating a closed-loop security system that adapts to threats in real-time
2Reliability
If information is encrypted during transmission, then security is improved during transit, but the information must be decrypted at the destination where it becomes most vulnerable
Solution Approach 1:
The system performs preliminary security actions by establishing a secure, monitored viewing environment before decryption occurs. The physical or virtual secure zone is prepared in advance with security measures already in place, so when decryption happens, the information is immediately protected rather than exposed
Solution Approach 2:
The system introduces an intermediary secure viewing environment between the decryption process and the final display. This intermediary layer includes controlled physical spaces, monitored display areas, or virtual secure zones that mediate the transition from encrypted to decrypted state, preventing direct exposure to unauthorized access
3Reliability
If screen saver software is used to protect unattended screens, then privacy is improved after a delay, but the information remains vulnerable during the delay period
Solution Approach 1:
The system performs preliminary security actions by detecting unattended conditions and initiating security measures immediately, without waiting for a predetermined time delay. Motion sensors, keyboard/mouse activity monitors, or facial recognition systems detect absence and trigger obscuration or termination of display instantly, eliminating the vulnerability window entirely
4Object-affected harmful factors
If privacy screens are positioned over computer displays, then peripheral viewing is prevented, but the screens can be easily detached and do not address unauthorized access to unattended information
Solution Approach 1:
The system merges multiple security functions into a unified solution that combines physical privacy screen features with electronic monitoring and control systems. The privacy screen is integrated with sensors, processors, and actuators that enable automatic detection of unauthorized viewing and active response measures, transforming a passive barrier into an active security system
Solution Approach 2:
The privacy screen system incorporates dynamic elements that allow it to respond to threats in real-time. The screen can change its optical properties, be automatically repositioned or detached, or trigger other security measures based on detected viewing conditions, making the protection adaptive rather than static
Data Source
AI summary
A communication system comprising a controlling server coupled to a controlled server via a socket communication channel to stream sensitive information to a desktop computer for viewing in a secured manner. The streamed information is not stored at the desktop. The controlling server streams the information to the desktop computer as long as the server is receiving a continuous uninterrupted flow of requests for information signals from the desktop computer. The user continuously depresses the mouse on the desktop to generate the continuous uninterrupted requests to view the sensitive information in a secure manner. The controlling server will immediately stop streaming the sensitive information and thus stop the display of the sensitive information upon detection of any interruption of the continuous transmission of request signals as would occur, for example, if the user were to unexpectedly leave the desktop unattended.
