CSD4CA: A Contextual Swipe Gesture Dataset for Continuous Authentication

CSD4CA is a contextual, multimodal swipe gesture dataset designed for continuous mobile authentication research. It contains data from 50 participants collected using a custom Android app on a Pixel 6a device, simulating real-world usage. Each user completed two sessions under three distinct conditions: seated, walking, and stress-induced. The dataset includes synchronized streams of touch interaction events (coordinates, timestamps, pressure, area) and motion sensor signals (accelerometer, gyroscope, magnetometer).
