A unique keystroke biometric dataset was collected from three online exams administered to undergraduate students in an introductory computer science course during a semester. Each exam contained five essay questions that required typing a response directly into a web page. Students took the three exams through the Moodle and their keystrokes were logged by a Javascript event-logging framework and transmitted to a server. For the first exam students were instructed to type normally with both hands, for the second exam with their left hand only, and for the third exam with their right hand only.

The dataset consists of 81 students who provided at least 500 keystrokes on each exam. Approximately 1/3 of all exam attempts occurred in an electronic classroom on standard desktop computers to ensure instructions were followed when typing with just one hand. The remaining students completed the exams individually on their personal computers, which was a mix of desktop and laptop computers.
