Device-native biometric authentication (such as Face ID and fingerprint scanning) is convenient but lacks the security needed for high-risk transactions. These systems can be bypassed using stolen devices, spoofing attacks, and synthetic identities.

Block Identity offers an advanced device-level biometric verification solution that ensures secure, real-time authentication with liveness detection and step-up verification.

Our AI-powered biometric technology detects presentation attacks, deepfakes, and stolen biometric data, providing an extra layer of protection where traditional authentication methods fall short.


Whether securing account access, approving high-value transactions, or preventing identity fraud, Block Identity delivers unmatched security and fraud prevention.

Liveness Detection

AI-powered technology that ensures biometric scans are performed by real, live individuals—not photos, deepfakes, or spoofed images.

Device-native biometrics often fail to detect sophisticated spoofing attempts, leaving systems vulnerable to fraud and unauthorized access. Block Identity’s advanced biometric verification enhances security by incorporating liveness detection and step-up authentication, ensuring that only legitimate users can access sensitive accounts and approve high-value transactions.


This approach significantly reduces fraud risks while maintaining a seamless and frictionless user experience.

Step-Up Authentication for Transactions

Dynamically request biometric re-authentication before processing high-value or sensitive transactions.

By requiring additional verification beyond the initial login, Block Identity adds an extra layer of security to safeguard sensitive transactions and account access.


This step-up authentication method strengthens fraud prevention by ensuring that only authorized users can complete high-risk actions, all while maintaining a seamless and frictionless user experience.

Cross-Device Identity Validation

Verify a user’s biometric data across multiple trusted devices for continuous authentication.

By preventing unauthorized device access and mitigating session hijacking risks, Block Identity ensures that only trusted devices can interact with sensitive systems.


This advanced security measure strengthens identity protection, particularly in multi-device environments, providing users and organizations with greater confidence in the integrity of their authentication processes.
