Biometric Data Tagging for Shared Vehicle User Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle sharing systems with autonomous driving, managing biometric data for multiple users in a single storage device poses security risks and slows down data loading due to the large amount of user information stored.
Innovation Solution
A user data management server that assigns unique tag numbers to each user, allowing biometric data to be stored in a single storage area, enhancing security and data access efficiency by managing data through a controller with an interface for receiving biometric data and user information, and utilizing a storage device with separate areas for basic, user, and temporary information storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple users' biometric data are stored in a single storage device, then data collection capability is improved, but security risk increases and data access speed decreases
Solution Approach 1:
The storage device is divided into multiple independent storage areas, with each area dedicated to storing biometric data of a single user. This segmentation isolates user data, preventing unauthorized access to other users' data and reducing security risks while maintaining the ability to store multiple users' biometric information.
Solution Approach 2:
A tag number is introduced as an intermediary identifier to manage and access biometric data. The tag number links the user interface to the specific storage area without exposing the actual data location or content, providing an additional layer of security and efficient data retrieval.
2Quantity of substance
If multiple users' biometric data are stored in a single storage device, then data collection capability is improved, but data access speed decreases
Solution Approach 1:
By dividing the storage device into separate storage areas for different users, the system enables direct access to specific user data without scanning or processing other users' data. This segmentation significantly improves data access speed while accommodating multiple users' biometric information.
Solution Approach 2:
The tag number serves as a direct pointer or intermediary that quickly locates the specific storage area for a given user. This eliminates the need to search through all stored biometric data, enabling rapid data retrieval even when multiple users' data are stored in the same device.
3Device complexity
If biometric data is stored without individual user identification, then storage simplicity is improved, but data management capability deteriorates
Solution Approach 1:
The tag number is introduced as a simple intermediary identifier that links the user interface to the corresponding storage area. This adds minimal complexity to the storage structure while dramatically improving data management capability, allowing the controller to efficiently access and manage each user's biometric data.
Solution Approach 2:
The tag number serves multiple functions: it identifies the user, locates the storage area, and enables data access. This universal identifier simplifies the overall system design by consolidating multiple management functions into a single mechanism.

AI summary
A shared vehicle management server of a vehicle sharing system, configured to allow a plurality of users to share and use vehicles, includes an interface configured to receive biometric data from the plurality of users, a storage device configured to store the biometric data received through the interface, and a controller configured to assign a unique tag number to each user and to manage biometric data of each user using the unique number. The controller manages to store the biometric data of each user in the same storage area using the unique tag number.
