Fraud Detection:Registration Fraud Detection features and parameters

Last Updated:Jan 10, 2026

Registration Fraud Detection helps businesses address account quality issues, such as fake and batch registrations, that arise during user growth. The service uses multi-dimensional feature analysis, such as behavioral profiling, risk networking, and sample comparison, to quickly assess the risk level of registered users. Businesses can then process registrations based on the returned results.
