Drive Video Recorder Access Control Using Encrypted File Storage
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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

AI summary
A method of controlling a drive video record system includes providing a camera module for monitoring an area around a vehicle, a first memory for storing video transmitted from the camera module, and a controller including a second memory for storing a computer program for controlling storage of the video and a processor for executing the computer program, where through execution of the computer program, the processor acquires password information of a user, acquires video or audio according to a set condition, and encrypts and stores the video or audio based on the password information.
