Summary
A new fingerprint matching algorithm, M3gl, overcomes limitations of minutia triplet methods. It achieves superior accuracy and faster matching times for fingerprint recognition.
Area of Science:
- Biometrics
- Computer Science
- Pattern Recognition
Background:
- Minutia triplet algorithms are crucial for fingerprint recognition but suffer from accuracy issues.
- Existing methods are sensitive to minutiae order, reflection, and relative directions.
Purpose of the Study:
- Introduce M3gl, a novel fingerprint matching algorithm.
- Address the limitations of current minutia triplet-based approaches.
Main Methods:
- Developed a new feature representation with clockwise-arranged minutiae.
- Implemented a similarity measure with triplet shifting for optimal correspondence.
- Incorporated a global matching procedure to maximize minutiae alignment.
- Added optimizations for faster non-matching triplet discarding.
Main Results:
- M3gl demonstrated higher accuracy compared to six other verification algorithms.
- The algorithm achieved the lowest matching time among tested methods.
- Performance was validated on FVC2002 and FVC2004 fingerprint databases.
Conclusions:
- M3gl offers an improved solution for fingerprint matching.
- The novel approach enhances both accuracy and efficiency in fingerprint recognition systems.
