Drive Recorder Access Control for Urgent Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drive recorders restrict access to high-urgency traveling images, such as those from collision accidents, preventing authorized parties like police or insurance companies from analyzing the cause of incidents due to access limitations set for vehicle occupants.
Innovation Solution
A drive recorder with a capture unit and access controller that captures and stores vehicle exterior images, setting access limitations for occupants but removing them during events of high urgency, such as collisions, allowing authorized access to these images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If access limitation is set for each occupant to protect personal information, then privacy protection is improved, but access to high-urgency traveling images by authorized parties deteriorates
Solution Approach 1:
The access control system dynamically adjusts access rights based on the detected urgency level of recorded events. When a high-urgency event is detected, the system automatically removes access limitations, allowing authorized parties (police, insurance companies) to access traveling images without requiring occupant authentication. For normal events, access limitation remains enforced to protect personal information.
Solution Approach 2:
The system changes the access control parameter (access limitation status) based on the urgency level parameter of recorded events. By detecting event characteristics and classifying them by urgency level, the system transitions between different access control states, enabling authorized access for high-urgency events while maintaining privacy protection for other events.
2Ease of operation
If access limitation is removed for all traveling images, then access by authorized parties is improved, but personal information protection deteriorates
Solution Approach 1:
The system segments traveling images into different categories based on event urgency levels. High-urgency images are separated from normal images and subjected to different access control rules. This segmentation allows authorized parties to access only the necessary high-urgency images without exposing all personal information contained in normal traveling images.
Solution Approach 2:
Different access control qualities are applied to different segments of traveling images based on their event characteristics. High-urgency images have relaxed access control (no authentication required for authorized parties), while normal images maintain strict access control (occupant authentication required). This local differentiation resolves the contradiction between accessibility and privacy protection.

AI summary
A drive recorder according to an embodiment includes a capture unit and an access controller. The capture unit captures an outside of a vehicle. The access controller sets access limitation, which limits an access from a person other than an occupant of the vehicle, for traveling images of the vehicle. The traveling images are captured by the capture unit and stored in a storage medium. When an event arising from the vehicle meets a predetermined condition that indicates at least level of urgency, the access controller removes the access limitation.
