Multi-level security authentication refers to combining OTP dynamic passwords, E2E end-to-end encryption, biometric facial recognition, CPF/CNPJ identity verification, PIX security and other authentication technologies to build a comprehensive security protection system. Through multiple independent security levels, it ensures that even if one layer is breached, other levels can still provide effective protection.

OTP (One-Time Password) is generated based on time algorithms and automatically updates every 30 seconds. Users can obtain verification codes through SMS, email, or dedicated APP. Each verification code can only be used once and has a time limit, greatly improving security. It supports deep integration with the PIX payment system, providing additional security for every transaction.

We use advanced algorithms and 3D facial modeling technology with liveness detection capabilities to effectively prevent fraud methods such as photos and videos. Recognition accuracy reaches over 99.9%, with response time at the millisecond level. We strictly comply with privacy protection regulations, with facial data encrypted to ensure user privacy security.

We have established real-time connections with official Brazilian databases to instantly query and verify the authenticity and validity of CPF (personal tax number) and CNPJ (business tax number). The system also performs cross-verification and checks blacklist status to ensure the accuracy and compliance of identity information.

End-to-end encryption uses AES-256 encryption standards, providing full encryption protection from user devices to our servers. Data uses SSL/TLS protocol during transmission and remains encrypted during storage. Keys are rotated regularly, and only authorized users can decrypt, ensuring data security throughout its entire lifecycle.

Based on Brazil's Central Bank PIX system security standards, we have added additional security levels. Including real-time transaction monitoring, abnormal behavior detection, multi-signature verification, etc. This maintains PIX's convenience and immediacy while greatly improving security, providing users with a more reliable payment experience.

We provide 24/7 security monitoring, real-time detection of abnormal behavior and potential threats. Regular security audits and vulnerability scans are conducted, and security strategies are updated promptly. We have also established a complete incident response mechanism to ensure rapid response and handling when issues are discovered. All security operations have detailed audit log records.
