Security Built for Trust
Zero Trust Level 2 Design
Every user, device, and request must be verified. Access is limited by role, tenant, and approval status.
Encrypted Private Fields
Full name, email, phone number, and sensitive records are encrypted before database storage.
Trusted Device Approval
Important access, login, and verification actions require approval from a registered trusted device.
QR Verification
QR codes confirm authenticity, validity, expiry, and revocation directly from the issuer record.
For Issuers
Protect your reputation. Control every verified record.
For Users
Your documents. Your approval. Always trusted.
Signatura Zero Trust Level 2 Flow
Provider operates the system, but private data access requires encryption, owner consent, trusted-device approval, and audit logs.
Issuer creates document record
Sensitive fields are encrypted
Encryption key stays outside provider access
Hash is generated and anchored
QR code is attached to document
Verifier requests access
Owner approves using trusted device
Temporary access token is issued
Access is verified and audit logged
Zero Trust rule: No document or private field should be readable by the provider, database admin, or system admin without authorized owner approval.
