Fingerprint Sequence Authentication to Replace Hackable PINs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal Identification Numbers (PINs) used for authentication in banking and other applications are vulnerable to hacking, compromising security.
Innovation Solution
A secure method using fingerprint sensors to scan and compare fingerprint images against a registered pattern, where the mapping table associates fingerprints with digits 0 to 9, allowing a unique sequence of fingerprints to replace PINs for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a PIN is used for authentication, then the authentication process is simple and easy to implement, but the security is compromised because the PIN can be hacked
Solution Approach 1:
The patent replaces the mechanical/digital PIN entry system with a biometric fingerprint recognition system. The fingerprint sensor captures unique physiological characteristics of the user's finger, transforming the authentication mechanism from something users can guess or steal (PIN) to something inherent and unique to each individual (fingerprint patterns), thereby significantly enhancing security while maintaining operational simplicity
Solution Approach 2:
The patent changes the fundamental parameter of authentication from a user-defined secret (PIN) to a biometric parameter (fingerprint characteristics). By utilizing the unique ridge patterns, minutiae points, and physiological features of fingerprints, the system transforms authentication into a more secure process that cannot be easily replicated or compromised, directly addressing the security vulnerability of PIN-based systems
2Reliability
If fingerprint images are scanned and compared, then security is enhanced, but the system complexity increases due to mapping tables and pattern comparison
Solution Approach 1:
The patent implements preliminary action by pre-registering and storing fingerprint templates during an enrollment phase. The system captures and processes fingerprint images in advance, extracting key features and creating comparison-ready templates. This preliminary processing reduces the complexity of real-time authentication, as the system only needs to compare against pre-prepared templates rather than performing complex analysis during the actual authentication moment
Solution Approach 2:
The patent uses copying by creating simplified representations or templates of the original fingerprint images. Instead of storing and comparing complete high-resolution fingerprint images, the system generates condensed template versions that capture the essential unique characteristics. This copying approach reduces data processing complexity while maintaining authentication accuracy and security
