I built a keystroke biometrics demo for continuous authentication

I’ve been working on behavioral biometrics and recently put together a public demo focused on keystroke dynamics.

The idea is simple: two typing samples are collected, and the model estimates whether they were produced by the same person based on timing and typing behavior.

The broader goal is continuous authentication using behavioral signals as an additional layer alongside conventional authentication, rather than repeatedly interrupting users.

I’m especially interested in edge cases like:

  • different keyboards or devices
  • fatigue and posture changes
  • one-handed typing
  • deliberate imitation
  • behavioral drift over time

You can try the demo here:

Feedback on the UX, model behavior, or failure cases is very welcome.
