Driver-Specific Dashcam Storage for Privacy and Evidence Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle black box systems fail to securely manage and protect the privacy of recorded images for multiple drivers sharing the same vehicle, leading to unauthorized access and potential deletion of important evidence.
Innovation Solution
A method and system for managing recorded images for each driver, which involves distinguishing between drivers through unique codes assigned to ignition keys, storing images in a specific format, and assigning authority for playback, deletion, and transmission, ensuring that only the driver's own recorded images can be accessed and managed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If recorded images are stored in a shared memory space for all drivers, then memory capacity utilization is improved, but privacy security deteriorates as any driver can access another driver's recorded images
Solution Approach 1:
The patent divides the shared memory space into separate storage areas for each driver, with each area accessible only to its corresponding driver. This segmentation maintains efficient memory utilization while preventing unauthorized access to other drivers' recorded images, thus resolving the privacy security issue.
2Ease of operation
If recorded images are deleted when memory capacity is full, then memory management is simplified, but important evidence may be lost due to unintended deletion
Solution Approach 1:
By segmenting the memory into driver-specific areas, the system ensures that deletion operations only affect the current driver's own recorded images, not other drivers' evidence. This maintains simple memory management while preventing unintended deletion of important evidence from other drivers.
Solution Approach 2:
The system introduces an intermediary authentication mechanism that verifies driver identity before allowing access to recorded images. This intermediary layer prevents unauthorized deletion or access, ensuring evidence preservation while maintaining ease of operation for authorized users.
3Device complexity
If all recorded images are stored without distinction, then storage process is simplified, but searching for specific driver's images becomes difficult
Solution Approach 1:
The patent organizes recorded images into separate folders or areas corresponding to each driver, with automatic identification and sorting based on driver ID. This segmentation maintains a simple storage process while enabling easy searching and retrieval of specific driver's images through intuitive navigation.
4Adaptability or versatility
If multiple drivers share one vehicle, then vehicle utilization is improved, but privacy protection deteriorates as previous occupants' recorded videos can be accessed
Solution Approach 1:
The system segments the recorded image storage into driver-specific areas, ensuring that each driver's privacy is protected while allowing multiple drivers to share the vehicle. This segmentation enables high vehicle utilization while preventing unauthorized access to personal recorded images.
Solution Approach 2:
An intermediary authentication system based on driver ID verification is introduced to control access to recorded images. This intermediary mechanism protects privacy by ensuring that only the recorded driver can access their own images, while allowing multiple drivers to share the vehicle freely.

AI summary
The present disclosure relates to a method for managing recorded images for each driver, including distinguishing between at least two drivers, storing recorded images of the vehicle in a specific format, and managing an authority to the recorded images according to the distinguishing, and a system for the same. According to the present disclosure, usability can be improved and privacy secured y storing a built-in cam video separately for each driver, and as the storage space capacity for each driver is distinguished, when old files stored while driving are deleted, only the images in the storage space the driver himself are deleted, thereby preventing existing data other drivers from being deleted unintentionally.
