Vehicle Authorization Using Approach Vector and Biometric Trust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional key fobs and remote keyless entry systems provide only a low level of security, are vulnerable to man-in-the-middle attacks, and lack the ability to identify authorized users, leading to rudimentary vehicle security.
Innovation Solution
A system that uses a computing device and biometric authentication to grant access to a vehicle, based on an approach vector and a chain of trust, providing multiple levels of security and personalized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional key fobs or keyless entry systems are used, then vehicle access is provided, but security level remains low and vulnerability to attacks increases
Solution Approach 1:
The authentication system is divided into multiple independent modules: approach vector determination module, biometric authentication module, and chain of trust verification module. Each module performs a specific function and contributes to the overall security, allowing the system to achieve high security through composition of simpler, specialized components rather than a single complex authentication mechanism.
Solution Approach 2:
The patent introduces a new dimension of authentication by determining the approach vector (direction and trajectory of approach) in addition to traditional biometric verification. This spatial-temporal dimension adds a layer of security that verifies not just who is approaching but how they are approaching, making the system resistant to replay attacks and unauthorized access attempts.
2Ease of operation
If traditional key or key fob is used, then vehicle access is enabled, but convenience decreases due to size and risk of loss or theft
Solution Approach 1:
The patent replaces mechanical key systems and electronic key fobs with a biometric authentication system that uses physiological characteristics (fingerprint, facial recognition, iris scan) for verification. This substitution eliminates the need for physical carriers that can be lost or stolen while providing more reliable security through unique biological identifiers.
Solution Approach 2:
The authentication system leverages the user's own biometric characteristics as the authentication credential. The user's body itself becomes the key, eliminating the need to carry external authentication devices. The system automatically captures and verifies biometric data without requiring the user to manually present any object.
3Adaptability or versatility
If conventional keyless entry systems are used, then remote access is provided, but vulnerability to man-in-the-middle attacks increases
Solution Approach 1:
The system performs preliminary verification of the approach vector and establishes a chain of trust before completing the authentication process. By verifying the spatial-temporal characteristics of the approach and pre-validating the authentication chain, the system prevents man-in-the-middle attacks from succeeding, as the attack would need to replicate not just the biometric data but also the precise spatial-temporal pattern of legitimate access.
Solution Approach 2:
The patent introduces an intermediary verification layer (the chain of trust mechanism) that mediates between the biometric authentication and the final access grant. This intermediary validates the authenticity of the authentication process and ensures that the approach vector corresponds to legitimate user behavior, blocking unauthorized access attempts even if biometric data is compromised.
Data Source
AI summary
A system provides a personalized and secure user experience to access a secured asset, such as a vehicle. A first communication is transmitted, and a second communication is received in response to the first communication. An approach vector is determined based on the first communication and the second communication. The approach vector is compared with a known approach vector, a request for authentication is transmitted based on the comparison. A response to the request for authentication is received, and access to an asset is granted based on the approach vector and the response to the request for authentication.
