Wearable Biometric Authentication Module with Physiological Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods, such as smart cards and biometric systems, are either intrusive, lack security, or require repeated measurements, making them inadequate for ensuring the authenticity of the user in secure transactions.
Innovation Solution
A wearable authentication module with a processing circuit, physiological parameter sensor, inactivation means, and wireless communication circuit that uses distinct physiological and biometric data to authenticate the user, ensuring secure and flexible identification through continuous or intermittent measurements and presence validation signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smart card with secret code is used for authentication, then the authentication process is simple and accessible, but the system becomes vulnerable to fraudulent use if the secret code is obtained by an unauthorized person
Solution Approach 1:
The authentication system is segmented into multiple independent components: a first biometric parameter (stored in the authentication module), a second biometric parameter (measured by the base), and a physiological parameter (measured by both). This segmentation ensures that no single component contains all authentication information, preventing fraudulent access even if one parameter is compromised.
Solution Approach 2:
The authentication module acts as an intermediary device worn by the user, containing secure storage for biometric data and serving as a bridge between the user and the base. This intermediary ensures that sensitive biometric data remains protected while enabling secure authentication through coordinated verification of multiple parameters.
2Reliability
If a subcutaneous chip is implanted for authentication, then the authenticity of the user is ensured, but the solution becomes intrusive and difficult to remove
Solution Approach 1:
The authentication functionality is extracted from the user's body (as in implantable chips) and placed in a separate wearable authentication module. This allows the system to maintain high security through biometric verification while enabling easy removal by simply taking off the wearable module, eliminating the intrusiveness of implantable solutions.
3Reliability
If a biometric control system with dedicated base is used, then the authentication is based on specific biometric data, but the security is limited as it requires repeated measurements and can only authenticate based on the particular biometric datum the base can measure
Solution Approach 1:
The authentication system is designed with multi-functionality, verifying three different types of parameters: a first biometric parameter (e.g., fingerprint stored in module), a second biometric parameter (e.g., facial recognition measured by base), and a physiological parameter (e.g., heart rate or temperature). This universal approach allows authentication through multiple biometric modalities, eliminating the limitation of single-biometric-type systems and reducing the need for repeated measurements of the same parameter.

AI summary
A module (10) for authenticating a person is characterised in that it comprises: - a processing circuit (102) comprising an authentication memory (104), - a sensor (106) of a physiological parameter of the wearer, - a means (108) of deactivating the circuit (102) sensitive to said sensor (106) and capable of deactivating the circuit (102) when said sensor (106) does not receive an expected physiological signal, - a wireless proximity communication circuit (110) with a base, capable of communicating with said base according to a protocol involving biometric data different from said physiological parameter and intended to be received by the module (10), - means (112) of transmitting presence confirmation signals to said base and/or of receiving presence confirmation signals, which are separate from said communication circuit (110).
