Remote Screen View Sharing with Selective Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online collaboration tools transmit entire screen content, including sensitive data, to all communication partners, and do not allow data evaluation by partners, as the image display does not permit such functionality.
Innovation Solution
A method where a display scheme and data elements are transmitted separately through distinct communication paths, with the display scheme sent via one path and data elements via another, allowing secure transmission and evaluation while controlling access to sensitive information based on partner authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If entire screen content is transmitted to all communication partners, then real-time screen sharing is achieved, but sensitive data protection is compromised
Solution Approach 1:
The screen content is segmented into two separate transmission channels: a first communication path transmits the display scheme (layout, formatting, structure), while a second communication path transmits only the authorized data element values. This segmentation allows selective sharing of information, enabling real-time screen sharing while protecting sensitive data by controlling which data elements are transmitted to which communication partners.
2Ease of operation
If image display is used for screen sharing, then visual representation is achieved, but data evaluation capability is lost
Solution Approach 1:
The display scheme acts as an intermediary structure that separates the visual representation function from the data content. The display scheme defines the layout and formatting without containing the actual sensitive data values, which are transmitted separately through the second communication path. This allows the receiving device to reconstruct the visual screen representation while also having access to the raw data values for evaluation and processing.
3Loss of information
If all data elements are transmitted to communication partners, then complete information sharing is achieved, but security control is reduced
Solution Approach 1:
Different communication partners receive different subsets of data elements based on their authorization levels. The system applies local quality by tailoring the data transmission to each specific communication partner's needs and security clearance, rather than uniformly transmitting all data to all partners. This enables complete information sharing with authorized users while maintaining security control by restricting sensitive data access to appropriate parties only.

AI summary
Method and apparatus for generating and updating a remote instance (2) of a screen view (1) for a communication device (13) during a communication session. The screen view (1) has a number of data elements (D) that are presented on the screen view (1) in accordance with a defined static or dynamic display schema (5). A display schema (5I, 5II) that at least partially corresponds to the display schema (5) of the screen view (1) is transmitted to the communication device (13) at least a first time via a first communication path (18), the values of at least one of the data elements (D) are transmitted to the communication device (13) via a second communication path (19) during the communication session, and the values of the data elements (D) and the transmitted display schema (5I, 5II) are combined by the communication device (13) in order to display the remote instance (2).
