Personal Meeting Recording Encryption Subsystem
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording systems for personal meetings lack the ability to ensure that recordings remain inaccessible without the consent of the key-holder participant, particularly in sensitive settings like medical treatments or attorney-client meetings, where privacy is paramount.
Innovation Solution
A recording system that incorporates an encryption subsystem capable of encrypting video and audio recordings, allowing decryption only with a personal key possessed by the key-holder participant, using various key types such as passwords, electronic keys, or biometric data, ensuring that access is restricted until authorized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recording systems are used to document personal meetings, then the ability to preserve meeting content is improved, but the risk of unauthorized access and breach of confidence increases
Solution Approach 1:
The patent applies preliminary action by encrypting the recording data immediately upon capture, before any potential unauthorized access can occur. The encryption key is securely stored and requires the key-holder participant's consent (via password, biometric, or electronic key) to decrypt, thus preventing breach of confidence while preserving the meeting recordation reliably
Solution Approach 2:
The patent introduces an intermediary encryption mechanism between the recording system and the stored data. The encryption subsystem acts as a mediator that transforms raw recording data into encrypted form, requiring authentication through personal keys (passwords, biometric data, or electronic keys) to access the original content, thereby eliminating unauthorized access risks while maintaining recordation reliability
2Object-affected harmful factors
If encryption is implemented to prevent unauthorized access, then privacy protection is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the recording system into distinct functional modules: a recording subsystem that captures meeting data, an encryption subsystem that secures the data, and a storage subsystem that holds encrypted recordings. This modular segmentation isolates the encryption complexity to a dedicated component, making the overall system manageable while providing robust privacy protection through encrypted storage
Solution Approach 2:
The patent implements self-service through automatic encryption that occurs seamlessly in the background without requiring user intervention. The system automatically manages key generation, data encryption, and secure storage, reducing the perceived complexity for users while maintaining strong privacy protection. The encryption process is transparent to the end-user, who simply needs to provide authentication when accessing recordings
3Object-affected harmful factors
If personal keys are required for decryption, then access control is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies universality by supporting multiple types of personal keys including passwords, biometric data (fingerprint, facial recognition, iris scan), and electronic keys. This multi-functional approach allows users to choose the most convenient authentication method for their needs, maintaining ease of operation while ensuring strong access control and unauthorized access prevention across different user preferences
Data Source
AI summary
A recording system that is designed to record a personal meeting between a service provider and a key-holder participant that includes an encryption subsystem, a recording means and a memory means. The recording means films the personal meeting and streams it to the encryption subsystem that encrypts the film and sends it to the memory means. The encryption subsystem includes an encryption means, a decryption means and a key reader. The encrypted film can be decrypted only by using a personal key of the key-holder participant.
