Communication Terminal Screen Capture Prohibition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack effective mechanisms to prevent unauthorized screen capturing of sensitive information during video conferences, particularly in scenarios where confidential information is shared among participants.
Innovation Solution
Incorporating circuitry in communication terminals to display images, receive instructions to prohibit screen capturing, and transmit information related to these instructions to other terminals, thereby disabling unauthorized screen capturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen capturing is allowed during video conferences, then users can freely capture and share content, but confidential information may be leaked to unauthorized users
Solution Approach 1:
The system applies preliminary anti-action by proactively disabling screen capturing functionality before any potential information leakage can occur. The communication terminal transmits prohibition information to the counterpart terminal, causing the capturing function to be disabled in advance. This prevents unauthorized users from capturing confidential information displayed during the video conference, resolving the contradiction between allowing screen capturing and preventing data leakage.
2Reliability
If screen capturing is prohibited during video conferences, then data privacy is protected, but users lose the ability to capture and share content
Solution Approach 1:
The system applies local quality by selectively enabling or disabling screen capturing functionality based on the specific context and user roles. The prohibition information can be configured to apply to specific users, specific content, or specific durations. This allows the system to maintain data privacy security while preserving capturing capability for authorized users under appropriate conditions, resolving the contradiction between security and functionality.
3Reliability
If prohibition information is transmitted to control screen capturing, then unauthorized capturing is prevented, but system complexity increases
Solution Approach 1:
The system applies the intermediary principle by using prohibition information as a mediator between the communication terminal and the screen capturing function. Instead of implementing complex direct control mechanisms, the system transmits prohibition information to the counterpart terminal, which then disables the capturing function. This intermediary approach simplifies the overall system architecture while achieving reliable screen capturing control.

AI summary
A communication terminal, a system, a method, and a control program stored in a non-transitory recording medium for controlling capturing of an image, each of which displays, on a display of the communication terminal, an image based on image data to be shared with a counterpart communication terminal; receives an instruction to prohibit capturing of a screen that includes the image based on the image data; and transmits, from the communication terminal to the counterpart communication terminal, information related to the instruction to prohibit capturing of the screen.
