Synthetic Biometric Data Generation for Configurable Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer security systems face challenges in providing secure and configurable password management, as text passwords are difficult to remember but lack configurability, while biometric passwords are unchangeable and less secure when compromised.
Innovation Solution
The generation of synthetic biometric data by combining biometric and non-biometric data using a device, which allows users to create or reset passwords through enrollment or authentication phases, using features like fingerprint, iris scan, or speech signals, and converting these into authorization data that can be securely stored and compared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric passwords are used, then security is improved, but configurability deteriorates
Solution Approach 1:
The patent creates a synthetic copy of biometric data that combines actual biometric information with randomly generated data. This synthetic biometric data serves as a configurable representation that can be changed by the user while maintaining security properties. The copying process allows the system to work with modified versions of the original biometric data, enabling password changes without altering the actual biological characteristics.
Solution Approach 2:
The system changes parameters by combining fixed biometric data with variable random data. The synthetic biometric data structure includes both immutable biometric components and mutable random components, allowing users to change their password by regenerating the random portion while keeping the biometric portion constant. This parameter change approach resolves the contradiction by making the password configurable while maintaining security based on the unchangeable biometric data.
2Adaptability or versatility
If text passwords are used, then configurability is improved, but ease of operation deteriorates
Solution Approach 1:
The system replaces the need for users to remember complex text passwords by creating a synthetic biometric copy that can be authenticated through biometric scanning. Users interact with the system through familiar biometric methods (fingerprint, iris, face scan) rather than memorizing and typing long passwords, significantly improving ease of operation while maintaining configurability through the synthetic data structure.
3Ease of operation
If biometric passwords are used, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The patent creates a composite authentication system that combines biometric data with randomly generated data to form synthetic biometric data. This composite structure maintains the ease of operation provided by biometric scanning while improving security by adding a layer of cryptographic randomness. The composite data structure ensures that even if the biometric component is compromised, the random component provides additional security protection.
Data Source
AI summary
A method of selectively authorizing access includes obtaining, at an authentication device, first information corresponding to first synthetic biometric data. The method also includes obtaining, at the authentication device, first common synthetic data and second biometric data. The method further includes generating, at the authentication device, second common synthetic data based on the first information and the second biometric data. The method also includes selectively authorizing, by the authentication device, access based on a comparison of the first common synthetic data and the second common synthetic data.
