Secured Multicast System Presentation Layer Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure web communication protocols fail to effectively manage varying security levels within communities, leading to potential unauthorized access and information exposure during real-time interactions.
Innovation Solution
The system implements automatic real-time filtering and information object selection at the presentation layer, allowing users with different security levels to participate in conferences while only accessing authorized content, using a processor and memory to create and associate digital objects with security levels, and multicasting presentations based on receiving device security levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate meetings are set based on security levels of participants, then information security is improved, but device complexity and operational complexity increase
Solution Approach 1:
Multiple security-level meetings are merged into a single unified meeting space. Participants with different security levels can attend the same meeting while only accessing content appropriate to their clearance level, eliminating the need to organize separate meetings for each security tier.
Solution Approach 2:
Meeting content is segmented into multiple security levels with different access permissions. The system divides information objects into security categories (e.g., public, confidential, secret) and applies filtering rules so that each participant automatically receives only the portion of content they are authorized to view, while remaining in the same meeting instance.
2Reliability
If security filtering is applied at the data layer, then information security is improved, but flexibility in presentation and user experience deteriorates
Solution Approach 1:
The system moves security filtering from the data layer to the presentation layer, adding a new dimension of control. Instead of filtering data before transmission, the system transmits all data but applies security filters during presentation based on user credentials, allowing the same data to be presented differently to different users without compromising security or flexibility.
Solution Approach 2:
A presentation-layer intermediary component is introduced that sits between the data source and the user interface. This intermediary applies security filtering rules dynamically based on user authentication, allowing flexible presentation formats while maintaining security controls without requiring data layer modifications.
3Reliability
If manual security level matching is performed for each user, then information security is improved, but productivity and ease of operation decrease
Solution Approach 1:
The system implements automatic security level matching where participants' security clearances are automatically detected and applied upon joining the meeting. The system self-adjusts content visibility based on user credentials without requiring manual intervention from meeting organizers, eliminating time-consuming manual security configuration.
Solution Approach 2:
Security filtering rules and user credential verification are established in advance before the meeting begins. The system pre-configures security policies and automatically applies them when users join, eliminating the need for real-time manual security management during the meeting setup and execution.
Data Source
AI summary
The system may provide automatic real-time filtering and information object selection, which may occur at the presentation layer. Presentations may be tailored on a per user basis. Users with different security levels can participate in a video conference call at the same time and only view what their security clearance allows.
