Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication methods for financial transactions are insecure, prone to hacking, and cumbersome, especially in wireless communication environments, as they rely on password-based systems that can be easily compromised and do not effectively utilize biometric data for verification.
Innovation Solution
An authentication system utilizing elliptic curve cryptography (ECC) and the elliptic curve Diffie-Hellman (ECDH) algorithm, combined with biometric data from fingerprint ridges, including the activity level of sweat glands, to generate and verify secure authentication codes, reducing the need for digital signatures and password inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password-based authentication is used, then the authentication process is simple, but the security is low and the system is prone to hacking
Solution Approach 1:
The patent replaces the mechanical password input system with a biometric recognition system that uses fingerprint sensors and electrodermal activity detection. This substitution eliminates the need for users to manually input passwords, thereby maintaining ease of operation while dramatically improving security through unique physiological characteristics that cannot be easily replicated or stolen.
Solution Approach 2:
The patent changes the authentication parameter from something the user knows (password) to something the user is (biometric characteristics). By measuring physiological parameters such as fingerprint ridge patterns and electrodermal activity levels, the system achieves both operational simplicity and high security, as these biological parameters are inherent to the user and difficult to compromise.
2Reliability
If certificate-based authentication is used, then the security is improved, but the authentication process becomes cumbersome and time-consuming
Solution Approach 1:
The patent extracts the essential security verification function from the complex certificate-based authentication process. Instead of requiring users to manually input passwords and digitally sign certificates, the system extracts biometric characteristics directly from the user's fingerprint and electrodermal activity, providing equivalent security through a much simpler process.
Solution Approach 2:
The biometric authentication system enables self-service authentication where the user's own physiological characteristics serve as the authentication credentials. The fingerprint sensor and electrodermal activity detector automatically capture and verify the user's identity without requiring manual intervention, certificate management, or complex authentication steps, thus improving convenience while maintaining security.
3Reliability
If OTP device is used, then the hacking risk is reduced, but the device complexity increases and the user bears authentication responsibility
Solution Approach 1:
The patent merges multiple authentication functions into a single integrated system. The fingerprint sensor, electrodermal activity detector, and authentication logic are combined in one device, eliminating the need for separate OTP devices and reducing overall system complexity. This unified approach maintains high hacking resistance while simplifying the authentication infrastructure.
Solution Approach 2:
The authentication system uses the user's own body as the authentication device. By measuring physiological characteristics such as fingerprint patterns and electrodermal activity, the system eliminates the need for external OTP devices or tokens. This self-service approach reduces device complexity while maintaining strong security, as the user's biology becomes the authentication credential.
4Reliability
If multiple authentication methods are used, then the security is enhanced, but the authentication time increases and the process becomes cumbersome
Solution Approach 1:
The patent performs preliminary authentication actions by capturing both fingerprint and electrodermal activity data simultaneously in a single interaction. Rather than sequentially applying multiple authentication methods, the system prepares and verifies multiple biometric parameters in parallel, significantly reducing authentication time while maintaining enhanced security through multi-factor biometric verification.
Solution Approach 2:
The patent merges fingerprint recognition and electrodermal activity detection into a single integrated authentication process. By combining these two biometric methods simultaneously rather than sequentially, the system achieves enhanced security through multi-factor verification while minimizing authentication time and user effort, as both measurements occur during one interaction.
