 # Liveness Detection Dataset: iBeta level 2 advanced mask attacks (5 K videos)
-Anti-Spoofing Paper Attacks iBeta 2 - 5,000 videos
-4 different attack types, advanced paper attacks for Liveness Detection
+This advanced paper mask attack dataset focuses on **complex paper-based presentation attacks** for **face anti-spoofing**, **liveness detection**, and **biometric face recognition** systems. The dataset contains **5,000 videos** across **7 distinct attack scenarios** - including printed-attribute photos, cut-out photo masks, photo masks worn by actors with real accessories (wigs, hats, glasses)
+
+Recorded from **25 participants** across **iOS and Android devices** with balanced gender mix and multi-ethnic representation (Caucasian, Black, Asian, Latinx). Active-liveness phases (fixed, zoom-in, zoom-out) are included for robust **presentation attack detection (PAD)** model training. Aligned with the **ISO/IEC 30107-3** standard and designed for **iBeta Level 2** certification preparation
