Authentication
The general model for Keystroke Dynamics-based authentication involves several critical steps, from capturing raw typing data to making an authentication decision. This sequential process ensures a robust and reliable identification of legitimate users.
1.83%
Lowest Equal Error Rate (EER) Achieved with Keystroke Barcoding
This groundbreaking EER was achieved using a one-class Support Vector Machine (SVM) classifier with a novel barcoding framework, significantly outperforming previous methods and setting a new benchmark for authentication accuracy in KDA.
Advanced ML/DL Techniques & Performance
Modern KDA systems leverage sophisticated Machine Learning and Deep Learning algorithms to analyze typing patterns, offering superior accuracy and robustness. The table below highlights key performance metrics from various approaches.
| Technique | Dataset | EER (%) | Accuracy (%) |
|---|---|---|---|
| Keystroke Barcode Generation (fbsp2 – 0.1 – 1.5) | Author Dataset | 1.83% | - |
| XGBoost Algorithm | Author Dataset | - | 93.60% |
| GoogleNet | Author Dataset | 4.89% | - |
| Isolation Forest | CMU Dataset | - | 90% |
| Hidden Markov Models (HMMs) and Gaussian Modelling | Web-Based Keystroke Dataset | 2.54% | - |
| Keystroke Vectors | Author Dataset | 3.33% | 96.67% |
Keystroke Barcode Generation, specifically with the fbsp2 – 0.1 – 1.5 wavelet, demonstrates the lowest EER, making it ideal for high-security applications. XGBoost stands out for its high accuracy, offering a balanced approach for many enterprise scenarios, while GoogleNet showcases the potential of deep learning for complex data classification.
Case Study: Keystroke Barcoding in Financial Institutions
Problem: Financial institutions face escalating cyber threats, requiring advanced, non-intrusive authentication to protect sensitive data and prevent fraud.
Solution: Implementing Keystroke Barcode Generation (fbsp2 – 0.1 – 1.5) provides a robust biometric solution. This technique analyzes unique typing patterns, converting them into compact, secure barcode images for real-time authentication.
Impact: This method significantly reduces false positives and negatives, creating a strong barrier against security attacks. Its high accuracy and low EER (1.83%) make it indispensable for scenarios with zero tolerance for unauthorized access, ensuring the integrity of financial systems and customer data.
