Drive Recorder Video Access Control for Shared Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the market for shared vehicles such as rent-a-car and car sharing expands, there is a growing need for a mechanism to prevent unauthorized access to video recordings from drive recorder cameras, which may contain personal or sensitive information of multiple users.
Innovation Solution
A video processing device that associates video recordings from a drive recorder camera with identification information of the user, allowing access only to the identical user by determining whether the access requestor matches the user identified at the time of recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the drive recorder camera is shared by multiple users, then the usability and adaptability of the system is improved, but the privacy protection and security of video recordings deteriorate
Solution Approach 1:
The system segments video recordings by associating each video with identification information of the user who operated the drive recorder camera. This segmentation allows different users to access only their own videos, preventing unauthorized access while maintaining shared vehicle usage. The associated information structure divides the video storage into user-specific segments.
Solution Approach 2:
The processor acts as an intermediary between the video storage and access requests. It determines whether to permit access by comparing the access requestor with the identified user, thereby mediating the security control mechanism that enables shared usage while preventing unauthorized access.
2Object-affected harmful factors
If access control mechanisms are implemented to protect video recordings, then the privacy protection is improved, but the device complexity increases
Solution Approach 1:
The processor performs multiple functions: it stores associated information, identifies users, determines access rights, and controls video playback. By consolidating these functions into a single processor, the system achieves comprehensive privacy protection without proportionally increasing device complexity.
Solution Approach 2:
The system automatically determines access rights by comparing the access requestor with the identified user without requiring manual intervention. This self-service mechanism simplifies the access control process while maintaining strong privacy protection.

AI summary
A video process device stores associated information in which video shot by a drive recorder camera and identification information indicating identification result of a user of the drive recorder camera are associated, determines whether an access requestor to the video and the user of the drive recorder camera when the video was shot by the drive recorder camera are identical based on the identification information when an access to the video is requested, and permits the access requestor to access to the video when the access requestor to the video and the user of the drive recorder camera when the video was shot by the drive recorder camera are identical.
