Virtual Meeting Recording Encryption With Threshold Key Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual meeting recordings are vulnerable to data compromise due to insecure storage and access, as they can be hijacked or accessed by unauthorized individuals, especially when participants are not physically present.
Innovation Solution
A security encryption system encrypts virtual meeting recordings and generates participant-specific encryption keys, requiring a threshold of unique key shards for access, ensuring secure storage and controlled access to the encrypted recordings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual meeting recordings are stored in accessible storage systems, then ease of access and retrieval is improved, but security and vulnerability to unauthorized access worsens
Solution Approach 1:
The encryption key is divided into multiple key shards that are distributed to different participants. No single participant or unauthorized entity can access the full key alone, thus securing the recordings while allowing authorized access when sufficient key shards are combined.
Solution Approach 2:
A secure encryption system acts as an intermediary between the stored recordings and authorized participants. This intermediary verifies and aggregates key shards before granting access to the decrypted recordings, preventing direct unauthorized access to the storage system.
2Reliability
If encryption is applied to virtual meeting recordings, then security and protection from unauthorized access is improved, but complexity of the storage and access system worsens
Solution Approach 1:
The encryption system performs multiple functions: it encrypts recordings, generates and distributes key shards to participants, verifies aggregated keys, and controls decryption access. This multi-functionality consolidates what could be multiple separate systems into a single unified solution.
Solution Approach 2:
The system automatically manages the encryption and decryption processes without requiring manual intervention. Key shards are automatically distributed to participants, and the system self-verifies the aggregated keys before granting access to recordings.
3Reliability
If multiple key shards are required for access, then security against single-point compromise is improved, but difficulty of authorized access worsens
Solution Approach 1:
The system provides feedback mechanisms to guide participants through the key aggregation process. It verifies and communicates the status of aggregated key shards, confirming when sufficient keys are collected to authorize access, thus simplifying the multi-step process.
Solution Approach 2:
Key shards are pre-distributed to participants during or before the virtual meeting. This preliminary distribution eliminates the need for complex real-time key exchange protocols during the access process, as participants already possess their designated key shards when needing to access recordings.
