hCaptcha Synthetic Identities is a fraud detection product designed to identify and block synthetic and cloned identities during account onboarding. The product analyzes signals from user sessions to detect fake or synthetic accounts before they can be used for malicious activity such as fraud or abuse. It provides a rules engine that lets teams build and backtest adaptive rules, enforcing responses in real time such as rate limiting, MFA challenges, or blocking suspicious applications. It includes native invisible or dynamic challenges intended to replace external CAPTCHA solutions, and native MFA using pull-based SMS and OTP authentication as an alternative to third-party MFA providers. For investigation, the product offers analytics, real-time insights, and anomaly views that let teams review the full user journey, filter suspicious sessions, and identify attack patterns. It also provides access to hCaptcha's SOC for accelerated investigation and threat analysis support. The product is part of the hCaptcha Enterprise offering and is aimed at reducing onboarding risk from fake or duplicate account creation.</description> <parameter name="summary">Detects and blocks synthetic or cloned identities during real-time account onboarding

GeeTest Device Fingerprinting is a device identification and risk analysis product used to distinguish genuine users from fraudulent traffic across web and mobile applications. The product collects device and app-level attributes to generate a unique device identifier without relying primarily on identifiers such as IMEI or IDFA. It aims to maintain consistent fingerprints for a device across multiple apps and after app reinstallation. The system applies what the vendor calls Triple-Dimensional Review Technology, analyzing historical, attribution, and risk data to evaluate traffic on desktop and mobile. It generates risk labels (up to 40) covering device and behavior perspectives to flag suspicious requests, and visualizes relationships between devices and accounts using a graph convolutional network (GCN)-based device relationship graph. This is used to detect duplicate or linked accounts and map traffic requests to devices and accounts. Reported accuracy claims include over 99.5% fingerprint accuracy and a stated less-than-0.0001% chance of generating identical fingerprints for different devices. Use cases described include marketing (ad fraud prevention, ad targeting, data analysis), finance (fraud and identity theft prevention, transaction security), e-commerce (marketing, personalized recommendations, fraud prevention, account security), and gaming (anti-cheat, malicious behavior detection).</description> <parameter name="summary">Device fingerprinting and risk analysis product for fraud detection across web and mobile
