Behavioral Biometric Auth

STATUS: ACTIVE R&D / PROTO-SYSTEM

Engineered a privacy-preserving continuous post-login authentication framework for device hijack prevention. The system dynamically validates session identity by monitoring keystroke mechanics and mouse trajectory (KMT) dynamics.

>Methodology: Distance-preserving secure projection via Johnson-Lindenstrauss Lemma.
>Neural Classifier: Deep Support Vector Data Description (Deep SVDD) anomalies filter.
>Optimization: Hyperparameters optimized via Optuna framework.
