Video Conference Recording Access Control via Segmentation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Multi-user video conference sessions face challenges in securely managing recordings, as sensitive information is shared, and participants with lower access permissions may inadvertently or intentionally access confidential data.

Innovation Solution

Implementing a collaborative rights information management system that assigns and manages user access permissions dynamically during the video conference, using passwords and encryption to restrict access to recordings based on participant levels, and segmenting recordings to maintain confidentiality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If video conference sessions allow all participants to access recordings, then ease of operation is improved, but information security deteriorates

Engineering Contradiction:

Improveaccess to recordingsVSAvoidexposure to sensitive information

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements differential access rights where different participants receive different permission levels for accessing recordings. The system assigns specific segments of recordings to specific users based on their role and clearance level, ensuring that each user can only access the portions of the conference recording that are appropriate for their position in the organization.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent divides the complete video conference recording into multiple segments or clips, where each segment contains specific content that is relevant to particular users or groups. The system then selectively assigns these segments to different users based on their access permissions, allowing granular control over what each user can view while maintaining overall system ease of operation.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If video conference sessions record all content, then information completeness is improved, but information security deteriorates

Engineering Contradiction:

Improvecompleteness of recorded contentVSAvoidexposure to confidential data

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent segments the complete recording into multiple discrete clips or portions, each containing specific content from the video conference. This segmentation allows the system to preserve the complete recording for archival purposes while simultaneously controlling access to individual segments, so that sensitive portions can be restricted without losing the overall completeness of the recorded information.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different access quality levels to different segments of the recording. While the complete recording is maintained in its entirety, specific segments are marked with restricted access permissions that prevent certain users from viewing them, thereby preserving information completeness while protecting confidential data through localized access control.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If video conference sessions use dynamic permission management, then information security is improved, but device complexity increases

Engineering Contradiction:

Improveprotection of sensitive informationVSAvoidpermission management system

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements an automated permission management system that dynamically assigns and updates access permissions without requiring manual intervention from administrators. The system automatically monitors user roles, clearance levels, and segment assignments, and adjusts permissions in real-time based on changing conditions, thereby providing strong security protection while minimizing the operational complexity for users.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent employs dynamic permission structures where access rights are not fixed but can change automatically based on user actions, time, or system conditions. The system continuously evaluates and updates permission levels, allowing flexible and adaptive security management that responds to changing requirements without requiring complex manual reconfiguration by administrators.

Inventive Principle:

Principle #15Dynamics

AI summary

A host server information handling system executing a multimedia multi-user collaboration application (MMCA) may include a processor; a memory; a power management unit; a network interface device to receive and provide audio/visual (AV) data during execution of the MMCA for a video conference session; the processor configured to execute a collaborative rights information management system to: manage the recordation of a video conference session during the execution of the MMCA to create a recording of the video conference session and assign a first password to protect the recording of the video conference session as a default password; assign a security level to the recording of the video conference session; and permit access, via the network interface device, to the recordings of the video conference session by transmitting the password to those users who are associated with a higher user access permission level than the aggregated user access permissions and are authorized to access the recording.
