TCHAD-100: A Cross-Cultural Keystroke Dynamics Dataset from 100 Chadian Participants

TCHAD-100 is a behavioral biometric dataset dedicated to keystroke dynamics analysis, collected from 100 Chadian participants in a real-world academic environment. The dataset includes dwell times, flight times, demographic metadata, and typing preferences in a cross-cultural African context.The data were collected using a custom web-based acquisition platform and stored in a PostgreSQL database before anonymization and export. Each participant provided up to 60 keystroke samples using fixed and free-text phrases under controlled conditions.This dataset is designed to support research in behavioral biometrics, authentication systems, cybersecurity, and cross-cultural human\u2013computer interaction. TCHAD-100 is fully anonymized and shared under the CC-BY 4.0 license.
