Biometric Recognition Security Chip Physical Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biometric recognition systems lack strong security due to the vulnerability of biometric templates during transmission, storage, and calculation, as the division of security and non-security zones is logical rather than physical, making them susceptible to theft and forgery.
Innovation Solution
A device comprising a sensor, microprocessor, and security chip for biometric recognition, where the microprocessor performs image preprocessing and feature extraction, and the security chip stores and compares biometric templates, ensuring physical isolation from the system environment to enhance security through digital signing of recognition results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric templates are stored in the system memory for recognition, then recognition functionality is achieved, but security vulnerability increases due to potential theft and forgery of templates
Solution Approach 1:
The patent extracts the biometric template storage function from the main system memory and relocates it to a dedicated security chip. This physical separation removes the vulnerable component (template storage) from the potentially compromised environment (main system memory), thereby preventing theft and forgery while maintaining recognition functionality.
Solution Approach 2:
The patent segments the biometric recognition system into distinct functional modules: a sensor module for capturing biometric data, a microprocessor module for processing, and a security chip module for template storage and verification. This segmentation isolates sensitive operations in the security chip from the rest of the system, reducing overall security vulnerability.
2Reliability
If physical isolation of security processes is implemented, then security level is improved, but device complexity increases due to additional hardware components
Solution Approach 1:
The patent merges multiple security-related functions (biometric template storage, feature extraction, verification algorithms, and digital signing) into a single integrated security chip. This consolidation achieves physical isolation and enhanced security while minimizing the increase in device complexity by combining rather than multiplying components.
