Video Management System Affiliation-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video management systems restrict video sharing between teams, preventing members of one team from accessing match videos captured by the opposing team, while allowing unlimited access can lead to unauthorized distribution.
Innovation Solution
A video management system that includes a server managing match video data and a terminal capable of transmitting video requests with affiliation information, where the server determines the affiliation destination and transmits or rejects video data based on matching or non-matching affiliations, with a point-based system controlling access to ensure restricted distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video sharing is restricted to same-team members only, then video security is improved, but video utility and sharing capability deteriorate
Solution Approach 1:
The patent applies local quality by differentiating access rights based on the viewer's team affiliation relative to the video's team. Same-team members receive full access to their team's videos, while other-team members receive restricted access only to opponent videos. This localized differentiation resolves the contradiction by providing security where needed (cross-team access control) while maintaining utility (intra-team sharing).
Solution Approach 2:
The system dynamically adjusts video accessibility based on real-time affiliation matching between viewers and video content. The server evaluates the relationship between the requesting terminal's team and the video's team to determine access permissions. This dynamic approach allows the system to adaptively grant or restrict access, improving both security and utility simultaneously.
2Adaptability or versatility
If video sharing is expanded to multiple teams, then video utility is improved, but risk of unauthorized distribution increases
Solution Approach 1:
The server acts as an intermediary between video sources and viewers, controlling all video distribution flows. It evaluates affiliation information from terminals and makes authorization decisions based on the matching rules. This intermediary mechanism enables multi-team sharing while preventing unauthorized distribution, as the server mediates every access request and enforces the affiliation-based access control policy.
Solution Approach 2:
The system performs preliminary verification of affiliation information before granting video access. The server checks whether the terminal's team affiliation matches the video's team or opponent team criteria before allowing playback. This preliminary action prevents unauthorized distribution by blocking inappropriate access requests before they can result in video leakage.
3Reliability
If strict access control is implemented, then video security is improved, but system complexity increases
Solution Approach 1:
The access control system is segmented into distinct functional modules: an affiliation information acquisition unit that collects team data, a matching determination unit that evaluates affiliation relationships, and an access control unit that enforces permissions. This segmentation simplifies the overall system by breaking down the complex access control logic into manageable, independent components that can be implemented and maintained separately.

AI summary
A server of a video management system includes a control unit that, upon receiving the video transmission request and the affiliation information transmitted from the terminal, determines whether the video transmission request and the affiliation information correspond to a first case in which the affiliation destination indicated by the affiliation information and the affiliation destination of the affiliation video data are the same, a second case in which the affiliation destination indicated by the affiliation information and the affiliation destination of the affiliation video data are the same for a group and are different for a team, or a third case in which the affiliation destination indicated by the affiliation information and the affiliation destination of the affiliation video data are different for a group, the control unit transmitting the match video data to the terminal in the first case.
