Virtual Screen File Sharing for Sensitive Information Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing technologies in online conference services do not adequately prevent the sharing of information that is not intended to be shared among multiple users.
Innovation Solution
An information processing apparatus and method that allows users to designate specific files or folders for display on a virtual screen, which is then shared with other users only if they have the appropriate access authority, while keeping other files or folders hidden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen sharing is implemented to allow multiple users to view information, then information sharing capability is improved, but risk of unintended information exposure increases
Solution Approach 1:
The screen sharing functionality is segmented into multiple independent sharing modes: entire screen sharing, specific window sharing, and specific application sharing. This segmentation allows users to selectively share only the necessary portions of their screen, preventing unintended exposure of sensitive information while maintaining versatile sharing capabilities.
Solution Approach 2:
Different security levels and sharing permissions are applied to different regions or components of the screen. The system allows setting different access controls for different applications, windows, or screen areas, enabling fine-grained control over what information is shared with whom, thus preventing unintended information exposure while maintaining adaptability.
2Quantity of substance
If all files and folders are shared during screen sharing, then completeness of shared information is improved, but privacy and security control deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically detecting and categorizing files and folders before screen sharing begins. It pre-identifies sensitive information such as personal data, confidential documents, and system files, and prepares appropriate filtering or masking rules in advance. This allows the system to share complete necessary information while automatically excluding sensitive content, maintaining both completeness and security control.
Solution Approach 2:
An intermediary layer is introduced between the screen content and the sharing transmission. This intermediary component analyzes the screen content in real-time, identifies sensitive information, and applies filtering rules before transmitting to other users. This mediator enables complete sharing of non-sensitive information while automatically protecting privacy and security without requiring manual user intervention.
3Reliability
If automatic detection of sensitive information is implemented, then privacy protection is improved, but system complexity increases
Solution Approach 1:
The system implements self-service by automatically detecting, categorizing, and protecting sensitive information without requiring external intervention or complex configuration. Built-in algorithms automatically identify personal data, confidential documents, and other sensitive content based on file extensions, content patterns, and metadata. This self-service approach maintains high privacy protection while avoiding the need for complex manual configuration systems.
Solution Approach 2:
The system uses parameter changes by analyzing file properties, content characteristics, and metadata to automatically determine sensitivity levels. By monitoring changes in these parameters such as file types, content patterns, and access permissions, the system dynamically adjusts protection levels without requiring complex manual rules, thus maintaining privacy protection while managing system complexity.

AI summary
An information processing apparatus includes a processor configured to: in a case where a screen displayed on a display of a first device is displayed on a display of a second device different from the first device, receive a designation of a file to be displayed on a virtual screen different from the screen; and display the virtual screen on which the designated file is displayed, on the display of the second device.
