Confidential Data Filtering in Monitor Mirroring Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor mirroring systems fail to ensure confidentiality of sensitive data, as all data displayed on a local monitor are also shown on a remote workstation, potentially violating regulations and compromising data security.
Innovation Solution
A method and apparatus for monitor mirroring that identifies and filters data requiring confidentiality before display, allowing only filtered data to be shown on all monitors, with the option to perform filtering upstream of the graphical interface or only on remote monitors, ensuring compliance with confidentiality regulations and maintaining identical screen content for all users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If monitor mirroring is implemented to allow multiple users to view the same screen content, then the ability to share data is improved, but data confidentiality is compromised as all displayed data appear on both local and remote monitors
Solution Approach 1:
The patent extracts confidential data from the display output by implementing a filtering mechanism that identifies and removes sensitive information before it reaches the remote monitor. This allows the monitor mirroring function to continue operating while selectively taking out the harmful confidential elements, resolving the contradiction between data sharing and confidentiality protection
Solution Approach 2:
The patent introduces a filtering mechanism as an intermediary component between the display system and the remote monitor. This intermediary processes the display data, selectively blocking confidential information while allowing non-sensitive data to pass through, thereby mediating between the need for data sharing and the requirement for confidentiality protection
2Ease of operation
If all data are displayed on both local and remote monitors, then the ease of operation for multiple users is improved, but compliance with confidentiality regulations deteriorates
Solution Approach 1:
The filtering mechanism extracts and removes confidential data elements from the display stream before they reach the remote monitor, ensuring that only non-sensitive information is shared. This maintains ease of operation for authorized users while eliminating the harmful effect of regulatory non-compliance
Solution Approach 2:
The patent applies different display qualities to different locations in the system: the local monitor receives complete unfiltered data for full visibility, while the remote monitor receives filtered data with confidential elements removed. This local differentiation resolves the contradiction by allowing ease of operation at the local level while ensuring regulatory compliance at the remote level
Data Source
AI summary
A method and an apparatus for monitor mirroring in the display of data requiring confidentiality is disclosed, including a computer system, an identification unit that identifies the data requiring confidentiality, and a filter unit that filters the identified data requiring confidentiality, so that only the filtered data and data not requiring confidentiality are shown on the monitor. The screen content of the monitor can thereupon be mirrored onto a further monitor.
