Study Notes
Biometrics in Cyber Security
- Biometrics is a key to the future of data/cyber security, satisfying properties such as universality, distinctiveness, permeance, and collectability.
- Fingerprint recognition is one of the oldest and mature biometric technologies, with applications in many areas.
Fingerprint Recognition
- Ridge patterns on a fingerprint surface are formed by ridges and valleys, with ridges being dark and valleys being bright.
- Ridges and valleys generally run in parallel, bifurcating, and terminating at various points.
- Minutiae are the endpoints and crossing points of ridges, and singularities are regions where ridge lines assume distinctive shapes, classified as loop, delta, and whorl.
Biometric System
- A biometric system recognizes a person using a specific physiological and/or behavioral characteristic possessed by a person.
- Biometric systems can be classified as either verification or identification systems, depending on the application.
Fingerprint Recognition Approaches
- Approaches for fingerprint recognition are divided into three categories: minutiae-based, non-minutiae-based (image-based), and hybrid systems.
- Minutiae-based approaches involve extracting a set of minutiae from fingerprints.
- Integrated wavelet and Fourier Mellin transform (WFMT) is used for feature extraction in minutiae-based approaches.
Feature Extraction
- Two set of features, namely fuzzy features and invariant moment features, are obtained from the region of interest (ROI) of the fingerprint image.
- Fuzzy features are obtained by dividing the cropped image into non-overlapping square blocks, and reducing the dynamic range of moments using a logarithmic function.
- Invariant moment features are obtained using equations (10) and (11).
Accuracy of Proposed System
- The proposed system achieved an accuracy of 75% with linear kernel, 87.5% with RBF kernel, and 77.5% with polynomial kernel using fuzzy features.
- The proposed system achieved an accuracy of 92.5% with linear kernel, 95% with RBF kernel, and 90% with polynomial kernel using invariant moment features.
