Screen Sharing Suspension for Confidential Data Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing technologies inadvertently expose confidential or private information during video conference calls, posing security risks as sensitive data can be transmitted to receiving devices.
Innovation Solution
A method and system where the transmitting device periodically sends image data of a shared screen to a receiving device, suspends updating of image data when a user interface component involving confidential information is activated, and continues to transmit the suspended image data to prevent exposure of sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If screen sharing is continuously updated during video conference calls, then the real-time collaboration experience is improved, but confidential information may be inadvertently exposed to receiving devices
Solution Approach 1:
The system performs preliminary detection to identify when confidential information is being entered or displayed on the screen before transmitting it to receiving devices. By detecting confidential information input states in advance and pausing screen sharing updates at this stage, the system prevents confidential data from being transmitted while maintaining real-time collaboration for non-confidential content.
2Object-affected harmful factors
If screen sharing updates are paused to prevent confidential information transmission, then information security is improved, but the real-time collaboration experience deteriorates
Solution Approach 1:
The system applies different transmission qualities to different regions or time periods of the screen content. Instead of uniformly pausing all screen sharing updates, the system selectively pauses only when confidential information is detected, while continuing real-time transmission for non-confidential content. This localized approach to quality control maintains collaboration efficiency while preventing information leaks.
3Object-affected harmful factors
If the transmitting device monitors for confidential information to pause screen sharing, then information security is improved, but the device complexity increases
Solution Approach 1:
The transmitting device leverages existing system resources and mechanisms to detect confidential information states without requiring a completely new monitoring infrastructure. The device uses available input state information from the operating system or application layer to determine when confidential data is being entered, reducing the need for complex external monitoring systems while still achieving security goals.

AI summary
A method, transmitting device, and computer-readable storage medium are provided for sharing image data between a source device and at least one receiving device. In one implementation, a method is provided for periodically sending image data of a shared screen to the at least one receiving device using a sharing connection. The method also receives a request associated with activating a user interface component involving confidential information, suspends updating of the image data responsive to the received request, and periodically sends suspended image data to the at least one receiving device while updating is suspended.
