Fingerprint Sequence Authentication Against Spoofed Biometric Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch/proximity sensor systems for user authentication and identification are vulnerable to fingerprint spoofing, where a mold or reproduction of a fingerprint can deceive the sensor into recognizing a valid user, lacking sufficient security measures to differentiate between actual and replicated fingerprints.
Innovation Solution
A system incorporating fingerprint sensors and processors that capture sequences of fingerprints, determine orientation, and compare these sequences with a fingerprint sequence record, incorporating thermal sensors to differentiate between actual and replicated fingerprints, and using sequences and orientation patterns to enhance security, potentially involving Physical Unclonable Functions (PUFs) for encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single fingerprint sensor is used for authentication, then the ease of operation is improved, but the security against spoofing deteriorates
Solution Approach 1:
The authentication process is segmented into multiple sequential fingerprint captures rather than a single capture. The system divides the authentication operation into a sequence of steps where multiple fingerprints must be captured in order, making spoofing more difficult while maintaining ease of use through automated sequence management
Solution Approach 2:
The system dynamically adjusts the authentication process by capturing multiple fingerprints in sequence and verifying their consistency. The authentication mechanism transitions from a static single-fingerprint check to a dynamic multi-fingerprint verification process that adapts to the captured data
2Reliability
If multiple fingerprints in sequence are required for authentication, then the security against spoofing is improved, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically managing the multi-fingerprint capture sequence without requiring complex user intervention. The processor autonomously coordinates the sequential captures, stores the fingerprints, and performs verification, reducing the perceived complexity for the user while maintaining high security
Solution Approach 2:
The system performs preliminary actions by pre-storing valid fingerprint sequences and pre-configuring the authentication protocol. This allows the actual authentication process to simply compare new captures against pre-established criteria, reducing real-time complexity while maintaining security
3Reliability
If fingerprint orientation and sequence verification are implemented, then the security is improved, but the measurement precision requirements increase
Solution Approach 1:
The system changes the verification parameters by considering not just the fingerprint pattern itself but also the orientation and sequence of multiple captures. This multi-parameter approach increases security through orientation verification while distributing the precision requirement across multiple measurements rather than demanding extreme precision from a single capture

AI summary
A fingerprint sensor system and method is provided for enhancing biometric security. Fingerprints may be recorded according to a particular sequence and orientation. Fingerprint sequences may then be used to control the operation of devices, such as restricting content, or encrypting communications.
