Field notes
Its proposed Brainprint combines pointer movement, click timing, keystroke intervals and scrolling patterns; the page says typed content is not captured. GrayBrain is positioned as an additional check alongside an identity provider, passkeys and MFA, with application-side outcomes of allow, verify again, hold or deny. The research illustrations are expressly described as conceptual rather than measured data, so the page explains the model but does not establish its performance.
