Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods face security vulnerabilities due to the risk of biometric information being hacked or corrupted, leading to failed authentication processes when stored as fixed values.
Innovation Solution
A user authentication method that combines knowledge-based authentication information with biometrics-based authentication information using randomly generated data to create an authentication code, enhancing security and accuracy by processing user requests based on this code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric information is stored as a fixed value, then authentication processing is simplified, but security is compromised due to risk of hacking and corruption
Solution Approach 1:
The patent transforms static biometric authentication into a dynamic process by introducing random number generation. The authentication code is dynamically created by combining biometric information with randomly generated numbers, making each authentication attempt unique and preventing static storage vulnerabilities while maintaining processing efficiency.
Solution Approach 2:
The patent changes the parameter of biometric information from a fixed stored value to a variable authentication code that incorporates random numbers. This parameter transformation ensures that the same biometric data produces different authentication codes each time, enhancing security without complicating the authentication flow.
2Reliability
If random number data is combined with biometric information, then security is enhanced, but authentication processing complexity increases
Solution Approach 1:
The patent merges biometric information and random number data into a single authentication code through combination operations. This merging approach enhances security by integrating two independent factors while maintaining a unified processing flow that does not significantly increase system complexity.
Data Source
AI summary
Provided are a user authentication method and an electronic device performing the method. The method is performed under the control of a processor and includes inputting a user authentication request for identifying a user, generating random number data that corresponds to knowledge-based authentication information in the user authentication request, generating an authentication code by combining biometrics-based authentication information in the user authentication request and the random number data, and processing the user authentication request based on the authentication code.
