Biometric Authentication with Concurrent Dynamic Pattern Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biometric authentication techniques, such as fingerprint scanning, are vulnerable to unauthorized access due to spoofing, where an unauthorized user can gain access using a reproduction of the authorized user's fingerprint, lacking sufficient security to prevent unauthorized access to user equipment (UE).
Innovation Solution
Implementing a two-factor authentication method that combines fingerprint scanning with a concurrent display of a dynamically changing authentication pattern, such as a visual timer, color sequence, or shape pattern, requiring the user to maintain their finger on the sensor and lift it off during specific visual cues, ensuring that both the fingerprint scan and authentication pattern characteristics match stored values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication (fingerprint scanning) is used to access user equipment, then ease of operation is improved, but security is worsened due to vulnerability to spoofing attacks
Solution Approach 1:
The patent combines biometric authentication (fingerprint scanning) with a secondary authentication mechanism (authentication pattern recognition) into a unified authentication system. The processor simultaneously performs fingerprint matching and authentication pattern analysis, requiring both to succeed for authorization. This merging of two authentication methods maintains ease of operation while significantly improving security against spoofing attacks.
Solution Approach 2:
The authentication system uses a composite approach by integrating multiple authentication factors (biometric fingerprint data and behavioral authentication pattern) into a single authentication decision. The processor evaluates both the fingerprint match result and the authentication pattern characteristics together, creating a composite authentication mechanism that leverages the strengths of both methods to achieve both ease of operation and high security.
2Ease of operation
If a single biometric authentication method is used, then ease of operation is improved, but security is worsened due to insufficient verification layers
Solution Approach 1:
The patent merges multiple authentication verification layers (fingerprint biometric verification and authentication pattern verification) into a single integrated authentication process. The processor simultaneously executes both verification methods and requires both to succeed, creating a multi-layered security system that maintains operational simplicity while providing robust security through cumulative verification.
Solution Approach 2:
The authentication process is segmented into distinct verification stages: fingerprint scan acquisition, fingerprint matching against stored data, authentication pattern display, authentication pattern characteristic extraction, and final authorization decision. This segmentation allows each verification layer to be independently evaluated while contributing to the overall authentication outcome, providing both security through multiple checks and clarity in the authentication process.
3Device complexity
If fingerprint scanning alone is used for authentication, then device complexity is reduced, but security is worsened due to lack of additional verification
Solution Approach 1:
The processor is designed to perform multiple functions: it processes fingerprint scan data for biometric matching and simultaneously processes authentication pattern data for behavioral verification. The display component also serves dual purposes by showing both the authentication pattern to the user and potentially providing feedback on authentication status. This multi-functionality achieves enhanced security without proportionally increasing device complexity.
Solution Approach 2:
The patent combines fingerprint-based biometric authentication and authentication pattern-based verification into a single integrated authentication system. By merging these two authentication methods into one unified process handled by the existing processor and display components, the system achieves improved security while minimizing the increase in device complexity through efficient resource utilization.

AI summary
The present application relates to authenticating a user of a user equipment (UE). Specifically, the described aspects include presenting for display an authentication pattern on a display of the UE after receiving an input representing a scan of a fingerprint. The authentication pattern may be displayed while the fingerprint sensor continues scanning the finger. Further, the UE may receive a second input representing a removal of the finger from the fingerprint sensor and an authentication pattern characteristic of the authentication pattern. In some aspects, the authentication pattern may be a visual timer, a visual color pattern, and/or a visual shape pattern. The UE may compare the fingerprint scan with a stored fingerprint and the authentication pattern characteristic with a stored authentication pattern characteristic to determine whether to permit the user to access the UE in an unlocked state.
