Continuous Biometric Authentication for IoT Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods for IoT devices require frequent re-authentication, which is time-consuming and inefficient, necessitating a solution for continuous and real-time user authentication.
Innovation Solution
The proposed solution involves an apparatus comprising IoT devices equipped with biometric sensors and a server, where the monitoring engine on the IoT device continuously measures biometric attributes and transmits them to the server for authentication, allowing for passive, continuous, and real-time user authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent re-authentication is required for security, then authentication reliability is improved, but user convenience and time efficiency deteriorate
Solution Approach 1:
The system performs preliminary authentication by capturing biometric data (fingerprint, facial recognition, or iris scan) before the user initiates a transaction. This pre-authentication establishes a trusted session, eliminating the need for repeated authentication during the session and thereby improving user convenience while maintaining security reliability.
Solution Approach 2:
The patent implements continuous authentication by continuously monitoring biometric characteristics during the user session. The system maintains an ongoing verification of the user's identity through passive biometric monitoring, ensuring uninterrupted authentication reliability without requiring active user participation or repeated authentication actions.
2Reliability
If continuous biometric monitoring is implemented, then authentication reliability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent employs multi-functional biometric sensors that can perform multiple authentication types (fingerprint, facial recognition, iris scan) using a single device. This universal approach reduces overall device complexity by consolidating multiple specialized sensors into one versatile biometric authentication system that can adapt to different authentication methods as needed.

AI summary
Apparatus and methods for continuous real-time authentication are provided. The apparatus and methods may include using a biometric sensor on an Internet-of-things (“IoT”) device to measure a biometric attribute of a user. The measured biometric attribute may be transmitted to a server to compare to a stored biometric attribute and authenticate the user. The IoT device may continue to measure the biometric attribute of the user at a pre-determined interval. Each measurement may be used to authenticate the user. This continuous authentication process may take place without the user's conscious interaction with the IoT device. The apparatus and methods may include using the continuous authentication to process and approve a transaction the user requests.
