Solution Overview

Problem

Current drive video record systems lack security measures to prevent unauthorized access to stored video and audio files, which may contain personal information.

Innovation Solution

A method and system for controlling access to a drive video record system, utilizing a camera module, memory for video storage, and a processor to acquire and encrypt video or audio files using password, fingerprint, or face recognition information, and restricting access through biometric authentication or password input, especially in valet mode or when starting the vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If video and audio files are stored in the drive video record system, then the system can record and preserve driving data and surrounding environment information, but unauthorized persons can access and leak personal information contained in the stored files

Engineering Contradiction:
Improvesecurity of stored filesVSAvoidunauthorized access to personal information
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an encryption module as an intermediary between the storage module and unauthorized access attempts. This encryption module encrypts video and audio files using passwords or biometric information before storage, creating a security barrier that prevents unauthorized persons from accessing personal information while allowing authorized users to retrieve files through authentication

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the accessibility parameter of stored files by encrypting them with passwords or biometric data. The files are transformed from an accessible state to an encrypted state during storage, and only become accessible again when the correct authentication parameters (password or biometric information) are provided during retrieval

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the drive video record system is built-in with access control features, then security against unauthorized access is improved, but the system complexity and cost increase

Engineering Contradiction:
Improveaccess control securityVSAvoidsystem structure with encryption and authentication
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional authentication system that can use either passwords or biometric information (fingerprint, face recognition) for access control. This universal approach allows the system to provide robust security while accommodating different user preferences and scenarios, managing complexity through flexible, standardized authentication interfaces

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent performs preliminary authentication actions before allowing access to stored files. The system requires users to provide passwords or biometric information and verify their identity before decrypting and displaying video or audio files, preventing unauthorized access while maintaining a user-friendly interface

Inventive Principle:
Principle #10Preliminary action
