Biometric Authentication via Segmented Data Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication systems face security risks due to the storage of biometric information in multiple devices and servers, making them vulnerable to hacking and data breaches, and require users to perform additional operations for authentication across different services.
Innovation Solution
A user authentication device and system that uses wireless communication to securely distribute and store biometric information across multiple sub-devices and servers, allowing for encrypted authentication without the need for users to perform separate operations, by generating and combining sub-biometric information to create a complete biometric profile for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric information is stored in multiple devices and servers for authentication, then authentication convenience is improved, but security risk increases due to vulnerability to hacking and data breaches
Solution Approach 1:
The patent segments biometric information into multiple sub-biometric pieces and distributes them across different devices and servers. No single device stores the complete biometric information, reducing the security risk while maintaining authentication convenience. The authentication device collects necessary sub-biometric pieces from multiple sources to perform verification.
Solution Approach 2:
The patent introduces an authentication device as an intermediary that coordinates between the user's device and service providers. This intermediary manages the collection and verification of sub-biometric information without requiring the user to manually intervene in each authentication process, thus improving convenience while maintaining security through centralized control.
2Reliability
If complete biometric information is stored in one device for authentication, then authentication accuracy is improved, but security risk increases due to single point of failure
Solution Approach 1:
The patent divides complete biometric information into multiple sub-biometric pieces stored in different locations. The authentication device collects these pieces and combines them during verification, ensuring authentication accuracy is maintained while eliminating the single point of failure risk associated with centralized storage.
3Object-affected harmful factors
If sub-biometric information is distributed across multiple devices, then security is improved by reducing data exposure risk, but system complexity increases
Solution Approach 1:
The patent creates a universal authentication device that can interface with multiple service providers and manage various types of sub-biometric information. This multi-functional approach simplifies the user experience and reduces overall system complexity by providing a single point of management for distributed biometric data.
4Ease of operation
If user authentication is completed on designated device without separate operations, then user convenience is improved, but communication requirements between devices increase
Solution Approach 1:
The patent implements a feedback mechanism where the authentication device communicates authentication results back to the user's device and service providers. This automated feedback loop enables seamless authentication without requiring separate user operations, while the communication protocol is designed to minimize complexity through standardized data formats and procedures.
Data Source
AI summary
The present invention relates to an electronic device for performing user authentication on a user by using user biometric information in response to a request made by a user authentication request device. The user authentication request device transmits data obtained by sensing the body of a user adjacent thereto to the electronic device (a user authentication device) of the user to request user authentication, and receives authentication result data from the user authentication device.
