BioSealⓇ Demo

Generate and verify cryptographically signed Visible Digital Seals with biometric authentication.

Generate a BioSealⓇ Verify a BioSealⓇ

Generate

Create a BioSealⓇ barcode from form data and a face photo. The seal is cryptographically signed and embeds biometric data for identity verification.

Verify

Upload a BioSealⓇ barcode image and a face photo. The system verifies the cryptographic signature and matches the face against the embedded biometric template.

What is BioSealⓇ?

BioSealⓇ is a Visible Digital Seal (VDS) technology by id3 Technologies. It encodes identity data and biometric templates into a 2D barcode (QR code or Data Matrix), signed with ECDSA cryptography. VDS follows ISO 22376 and enables offline verification of document authenticity.

  • Cryptographic signature (ECDSA-P256)
  • Biometric face template embedding
  • Offline verification via trust chain
