Video Conference Server Security Attribute Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing systems lack effective security measures to manage and stream video data based on varying security levels of participating devices, leading to potential unauthorized access and compromised privacy.
Innovation Solution
A server-based method that generates conference video data and assigns security attributes to each device based on its security level, streaming appropriate video data with or without security data to ensure that only authorized participants can view sensitive content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same video data is streamed to all participants, then system complexity is reduced and ease of operation is improved, but security is compromised because unauthorized participants can access sensitive content
Solution Approach 1:
The video data stream is segmented into multiple versions based on security levels. The server divides the conference video data into different security categories (e.g., public video, restricted video, confidential video) and creates separate encrypted streams for each security level, allowing selective distribution to participants based on their authorization credentials
Solution Approach 2:
Different security encryption qualities are applied to different portions of the video data based on the sensitivity and participant authorization. Each participant receives video streams with encryption levels matched to their security clearance, ensuring that sensitive content is protected while public content remains accessible
2Reliability
If security data is added to video streams for all participants, then security is improved, but data transmission volume increases and productivity decreases
Solution Approach 1:
Security encryption is applied selectively rather than universally. The server assesses each participant's authorization level and applies encryption only to video portions they are not authorized to view, leaving public portions unencrypted or lightly encrypted to minimize bandwidth overhead while maintaining security
3Reliability
If security attributes are assigned to video portions, then security is improved by preventing unauthorized access, but device complexity increases due to additional processing requirements
Solution Approach 1:
Security attributes and encryption are applied to video portions during the encoding and distribution phase before reaching the participant devices. The server pre-processes the video stream, tagging and encrypting sensitive portions according to security policies, so that participant devices only need to decrypt and display rather than perform complex security assessments

AI summary
In one example embodiment, a method performed by a server may include: receiving user videos from a plurality of devices; generating conference video data that includes at least one portion of the user videos; assigning a first portion of the at least one portion a first security attribute for a first device that has a first security level; generating first security data corresponding to the first security attribute; streaming, to the first device, the conference video data with the first security data; and streaming, to a second device having a second security level higher than the first security level, the conference video data without the first security data.
