Behavioral biometrics uses subconscious interaction patterns such as typing rhythm, mouse movement, scrolling, and mobile touch gestures to build user profiles and verify identity continuously during a session. Unlike active methods such as fingerprint or facial scans, it operates passively in the background, producing dynamic confidence scores that can prompt MFA challenges or block suspicious activity when behavior deviates from an established profile. The approach can strengthen defenses against account takeovers, bots, payment fraud, and potentially suspicious new accounts, while also reducing repeated authentication demands for legitimate users. It is intended to complement rather than replace existing identity and fraud tools, but implementation requires careful attention to privacy regulations, transparent data practices, initial model training, changing user behavior, and the possibility of advanced imitation attempts. Didit positions its identity and fraud infrastructure as a platform for combining behavioral signals with KYC, KYB, transaction monitoring, wallet screening, and data from numerous sources through an API-based, pay-per-use service.
