Your idea is genuinely creative, but unfortunately, keystrokes and mouse movements can be faked. AI can now learn and generate synthetic behavioral patterns that mimic human typing rhythms and mouse movements well enough to fool authentication systems. cybersecurityinstitute
Machine learning models, particularly Generative Adversarial Networks (GANs), can be trained on behavioral data to inject continuous streams of synthetic, human-like keystrokes or mouse movements. While behavioral biometrics like keystroke dynamics were once considered "virtually impossible to spoof", the landscape has shifted dramatically. Hackers in 2025 began using AI to defeat continuous authentication systems that rely on these patterns. aratek
Some detection systems do look for "synthetic mouse-move signatures" si
