Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biometric template is registered and stored on server, then authentication accuracy is improved, but user privacy protection deteriorates and management cost increases
Solution Approach 1:
The patent extracts only the essential authentication function from the biometric template, converting it into a mathematical code that retains verification capability while removing personally identifiable information. The biometric template is transformed into a mathematical representation that can be processed and verified without storing the original biometric data, thus extracting the useful authentication function while discarding the privacy-risking personal information.
Solution Approach 2:
The patent introduces a mathematical code as an intermediary between the biometric template and the authentication system. This mathematical code serves as a mediator that preserves the authentication functionality while preventing direct access to the original biometric data. The server stores and processes this intermediate mathematical representation rather than the raw biometric template, thereby protecting user privacy while maintaining authentication accuracy.
2Reliability
If conversion parameter is stored in smart card or client device, then resilient authentication is improved, but device complexity and security management cost increase
Solution Approach 1:
The patent enables the server to perform the conversion and verification operations that previously required the conversion parameter to be stored in client devices. The server-side implementation of the conversion process eliminates the need for clients to store sensitive conversion parameters, making the system self-sufficient on the server side and reducing client device complexity and security management burden.
3Reliability
If biometric template is encrypted with conversion parameter, then security against template disclosure is improved, but user operation complexity increases
Solution Approach 1:
The patent automates the conversion process on the server side, eliminating the need for users to manually input or manage conversion parameters. The system automatically performs the mathematical conversion of biometric templates and handles the verification process, making the encrypted authentication transparent to users while maintaining strong security against template disclosure.
