Standalone 4-channel offline polygraph. Audio & sensor-based stress analysis.
Veras: Polygraph & Lie Detector is a standalone, 4-channel simulation and verification suite designed for entertainment, training, human resources (HR) gameplay exercises, and information verification. It transforms your device into an offline interactive polygraph assessment console. Engineered strictly for offline data analysis, training profilers, and data verifiers, this application operates 100% locally with zero internet access, guaranteeing maximum data privacy. Features: • 4-Channel Verification Grid: Real-time visual tracking of voice volume pitch, touch screen pressure dynamics, device tremor logging via accelerometer, and a synchronized virtual rhythm index. • Cascade Response Segmentation: Automatically organizes data logs into specific, reviewable response blocks (e.g., "Response #1, duration: 16s") based on user input. • Detailed Telemetry Overview: Expanding any recorded response block instantly generates 4 isolated micro-graphs calibrated strictly to that response's timeframe. • Integrated Decision Rule: The system uses an automated majority-voting log rule. If signal anomalies exceed the 30% threshold of the interval, the block is visually marked as either DECEPTION (red) or CREDIBLE (green). • Variable Speed Playback: Built-in analysis player supports variable speeds from 0.5x to 2.0x, enabling deep micro-expression and speech pattern review. SECURITY & PRIVACY BY DESIGN: • Absolute Offline Operation: The application does not request or use internet permissions. Local data storage prevents any external leaks. • Local SQLite Engine: All session parameter logs and encoded audio streams reside strictly within an isolated local database file. • Anti-Tampering Hash Protection: Closing a session seals all raw logs with a unique local cryptographic signature, ensuring data integrity against third-party alterations. • Secure Data Shredder: A one-click cascade deletion permanently wipes all related session files, logs, and temporary cache directly from the physical drive. Note: This application is a simulation and data logging tool intended for training, entertainment, and educational purposes only. It does not provide medical diagnosis, health monitoring, or real-world stress therapy management
