Vehicle Entry Authorization Using Wearable ID and Biometrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional key fobs for vehicle entry are cumbersome and can lead to unauthorized access if lost or stolen, posing safety risks.
Innovation Solution
A multi-step vehicle entry authorization system using biometric data, where a proximity/contact sensor detects a wearable device ID, prompting the user for biometric input via sensors like fingerprint, voice, or iris recognition, and verifies it against stored data to unlock the vehicle securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional key fobs are used for vehicle entry, then ease of operation is maintained, but security and reliability deteriorate due to risk of loss or theft
Solution Approach 1:
The patent replaces the mechanical key fob system with a biometric authentication system using optical sensors, capacitive sensors, or other biometric sensing mechanisms. This substitution eliminates the physical key that can be lost or stolen while maintaining user convenience through automatic detection of the user's presence or identity characteristics.
Solution Approach 2:
The system creates a digital copy or representation of the user's biometric characteristics (fingerprint, iris pattern, facial features) and stores it for authentication purposes. This digital copy replaces the physical key fob, allowing secure verification without requiring the user to carry or handle physical objects.
2Ease of operation
If key fobs are used for vehicle access, then ease of operation is improved, but safety deteriorates due to unauthorized access risks
Solution Approach 1:
The patent replaces the mechanical key fob system with a biometric authentication system using optical sensors, capacitive sensors, or other biometric sensing mechanisms. This substitution eliminates the physical key that can be lost or stolen while maintaining user convenience through automatic detection of the user's presence or identity characteristics.
Solution Approach 2:
The system introduces biometric data and authentication protocols as an intermediary between the user and the vehicle access system. This intermediary layer verifies the user's identity before granting access, preventing unauthorized entry while maintaining ease of operation for authorized users.
3Reliability
If biometric authentication is implemented, then security is improved, but device complexity increases due to multiple sensors and verification steps
Solution Approach 1:
The patent implements a multi-functional authentication system where a single control unit handles multiple authentication methods (optical sensing, capacitive sensing, biometric verification). This universal approach consolidates multiple functions into one system, managing complexity through integration rather than proliferation of separate components.
Solution Approach 2:
The system performs preliminary authentication checks using simpler sensors (optical, capacitive) before proceeding to more complex biometric verification. This staged approach simplifies the overall process by filtering out unauthorized attempts early and only engaging complex biometric analysis when necessary.

AI summary
Systems and methods for multi-step vehicle entry authorization utilizing biometric data are disclosed. A proximity/contact sensor (24) attached to a vehicle (10) receives a device ID from a wearable device (50; 51) of a user. A biometric sensor (20; 58) receives biometric data of the user. A control module (26) accesses a user database (32) storing authorized user information and determines whether the user is authorized for the vehicle (10) based on the device ID, the biometric data, and the user database (32). The control module (26) unlocks the vehicle (10) in response to a determination that the user is authorized for the vehicle (10).
