CA, September 2025 – ZeroBiometrics, a leader in privacy-preserving biometric authentication, today announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for its latest innovation in secure biometric verification. This newly allowed patent represents a significant milestone in ZeroBiometrics’ mission to deliver authentication solutions utilizing biometrically derived public/private key cryptography. ZeroBiometrics’ approach eliminates template storage while delivering cryptographic identity certainty, non-repudiation, and regulatory compliance. The company’s technology was the first to achieve an ISO/IEC 30136 compliance certificate, the international standard that ensures no biometric data or personally identifiable information (PII) is retained or can be reconstructed from stored authentication data.
“This milestone reinforces our position as an innovator in the field of biometric security,” said Alfred Chan, CEO of ZeroBiometrics. “With this new patent, we are strengthening our commitment to privacy-centric authentication methods that not only meet global regulations but also set a new benchmark for trust and transparency in digital identity.”
The patented technology introduces a novel mechanism to revoke and rotate the biometrically derived cryptographic keys and associated data that underpins authentication decisions made by the ZeroBiometrics algorithm. Importantly, this process does not require users to re-scan their face: once rotated, prior cryptographic outputs—including previously generated keypairs—are permanently invalidated. This capability forms the foundation of the policy-driven credential rotation capabilities embedded in ZeroFace™, building on the company’s existing intellectual property for template-free biometric confirmation. By ensuring that no biometric vectors or templates are ever stored, the solution delivers both revocation and rotation safeguards—critical defenses against data breaches and unauthorized replication.
With this patent, ZeroBiometrics expands its growing portfolio of intellectual property designed to protect users, enable decentralized identity verification, and power the next generation of AI-driven identity systems across financial services, critical infrastructure, and enterprise security –while advancing global standards for privacy-preserving authentication.
