Vehicle Biometric Data Access Control via Offset Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems in vehicles do not provide fine-grained control over user data access, often either allowing full access or restricting it entirely, failing to adapt to varying user authentication levels and location-specific conditions.
Innovation Solution
A system that identifies user-specific data based on biometric authentication and adjusts data access by modifying or offsetting location information, using algorithms to determine an offset location based on population density, traffic capacity, or geographical area characteristics, allowing selective presentation of data on vehicle displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If full access to user data is allowed in vehicle displays, then user convenience and data availability are improved, but data security and privacy protection deteriorate
Solution Approach 1:
The system applies different access control policies to different users based on their authentication credentials. Each user receives customized data access permissions tailored to their specific clearance level, allowing the system to simultaneously provide convenient access to authorized users while maintaining security through differentiated restrictions.
Solution Approach 2:
The access control system dynamically adjusts data visibility and accessibility based on real-time authentication outcomes. When a user authenticates, the system dynamically determines which data sets are visible, editable, or restricted, allowing flexible adaptation between security and convenience based on user identity and context.
2Reliability
If encryption methods are used to protect user data, then data security is improved, but computational cost and processing time increase
Solution Approach 1:
The system employs lightweight access control tokens or credentials that are computationally inexpensive to verify compared to full encryption/decryption operations. These authentication artifacts enable security checks with minimal processing overhead, providing adequate security without the high computational cost of cryptographic transformations.
Solution Approach 2:
The system extracts only the essential authentication attributes from user credentials needed for access determination, rather than performing complete cryptographic verification. This selective extraction of necessary security information reduces computational burden while maintaining adequate security for the access control function.
3Loss of information
If all user data is made available on vehicle displays, then information completeness is improved, but adaptability to different user authentication levels deteriorates
Solution Approach 1:
The system implements user-specific data profiles that define which data elements are visible or accessible to each authentication level. This allows the display to show complete information to fully authorized users while automatically restricting sensitive data for users with lower clearance, maintaining both information completeness and user-specific adaptability.
Solution Approach 2:
The data visibility configuration dynamically adapts based on the authenticated user's credentials. The system automatically adjusts which data sets are presented on displays according to the user's authentication level, providing full information access when appropriate and selective restriction when required, all without manual intervention.
Data Source
AI summary
A computer includes a processor and a memory, the memory storing instructions executable by the processor to collect biometric data of a vehicle user, identify a set of user-specific data from one or more stored sets of user-specific data based on the biometric data, and receive a request for a stored location. When the biometric data of the vehicle user match the stored biometric data, the instructions include instructions to display the requested location. When the biometric data of the vehicle user do not match the stored biometric data, the instructions include instructions to identify an offset location based on the requested location and a population density of the requested location and display the offset location.
