1. Study Title
Development of a typing-mode aware keystroke dynamics authentication system
2. Invitation to Participate
You are invited to participate in a research study. Please read this form carefully before you decide to participate.
3. Purpose of the Study
The purpose of this study is to design a continuous behavioral biometric authentication system using keystroke dynamics. The system aims to reduce false positives and detect impersonation attacks (including shoulder-surfing) by incorporating typing-mode awareness.
4. What Participation Involves
If you agree to participate, you will complete a set of mini-tasks such as:
- Composing an email based on provided bullet points
- Revising a short story written for a high-school project
- Browsing and searching various items
- Writing replies for a chatbot
- Typing a grocery list using autocomplete
The estimated time commitment is 15–20 minutes.
5. Risks and Discomforts
This study involves minimal risk. The primary risk relates to privacy. Although the content of what you type is not recorded, timing patterns between keystrokes are collected. While reasonable security measures are in place, there is a small risk of a confidentiality breach if research data were accessed without authorization.
You may also experience mild fatigue or minor hand or wrist discomfort from typing. You may stop participating at any time without penalty.
6. Benefits
You may not receive any direct benefit from participating. However, your participation may contribute to research in this area.
7. Voluntary Participation and Withdrawal
Your participation is voluntary. You may withdraw at any time without providing a reason and without consequence. If you withdraw, you may request removal of your data up to 30 days after participation, after which it may be anonymized and no longer identifiable.
8. Confidentiality and Data Protection
The following data will be collected:
- Participant metadata (e.g., age band, gender, handedness, keyboard type, device platform, spoken languages, and musical skills)
- Inter-keystroke intervals (timing between key press and key release)
Data will be stored securely using encrypted storage and access controls. Only the research team will have access. Data will be retained for a maximum of 7 years, after which it will be securely destroyed. No identifying information will be published. Results will be reported in aggregate form.
