Biometric Authentication Using Fingerprint Sequence Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face security concerns due to the increasing number of passwords required for processor-based systems, often leading to compromised security from using common passwords, and existing biometric security mechanisms like fingerprint sensors are not robust enough.
Innovation Solution
An enhanced secure identification process using a biometric sensor that involves placing different digits in a predetermined sequence or sliding them in specific directions to create a unique password pattern, which can include or exclude alphanumeric characters, providing a stronger physical encryption by converting existing passwords into biometric-based sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single fingerprint scan is used for identification, then the operation is simple and fast, but the security strength is insufficient
Solution Approach 1:
The patent segments the single fingerprint identification into multiple sequential fingerprint scans. Instead of relying on one scan, the system requires a sequence of multiple fingerprint scans to be performed in a specific order. This segmentation increases security because even if one scan is compromised, the entire authentication sequence is not invalidated, while maintaining operational simplicity through the natural flow of sequential scanning.
Solution Approach 2:
The patent introduces dynamic elements to the static fingerprint scan by requiring movement between multiple scanning positions or sequences. The system dynamically evaluates the sequence of scans rather than treating each scan as an independent event. This dynamic approach enhances security by making replication more difficult while keeping the operation straightforward for legitimate users.
2Reliability
If multiple passwords are used for different applications, then security coverage is improved, but user confusion and password management complexity increase
Solution Approach 1:
The patent creates a universal multi-factor authentication system that can be applied across multiple applications and systems. Instead of requiring different passwords for each application, the system uses a standardized sequence of fingerprint scans that works universally. This single multi-functional authentication mechanism provides broad security coverage while simplifying user management, as users learn one authentication pattern applicable throughout.
3Ease of operation
If a common password is used for multiple applications, then ease of use is improved, but security is greatly compromised
Solution Approach 1:
The patent adds temporal and sequential dimensions to the authentication process. Instead of a static password or single fingerprint scan, the system requires a sequence of scans performed in a specific order over time. This dimensional transformation maintains ease of use through muscle memory of the scanning sequence while dramatically improving security, as the temporal sequence cannot be replicated by simply observing a single scan.
Data Source
AI summary
In one embodiment, a method includes receiving an ordered sequence of biometric inputs from a user via a biometric sensor, determining if each of the ordered sequence matches a corresponding entry stored in a table that includes a stored ordered sequence of biometric inputs corresponding to a password pattern of the user, and if so, enabling the user to access the processing system, otherwise preventing the user from accessing the processing system. Other embodiments are described and claimed.
