Advanced digital identity credentials offer significant advantages, including virtually uncompromisable security and simple verification. With VDS Bio and IDB, kinegram.digital provides highly secure, ICAO-aligned 2D barcode solutions that stand out for their efficiency and convenience.

The Need for Secure Digital Identity Credentials

From visa documents to fishing permits, from driver’s licenses to campus badges, identity tokens must be highly counterfeit-resistant and easily verifiable. Ongoing advances in digitization and ever-growing numbers of international travelers drive the quest for secure and highly efficient digital identity credentials.

For effective and reliable deployment, digital credentials need to meet stringent demands for security and counterfeiting resilience. On a global scale, the International Civil Aviation Organization (ICAO) developed specifications for the creation of trustworthy, interoperable digital credentials.

VDS and IDB: ICAO-Compliant 2D Barcodes as Digital Identity Tokens

Visible Digital Seal (VDS) elements are cryptographically encoded 2D barcodes that can be used digitally or printed on physical documents. They enable on- and offline verification of who issued a document and whether its data were altered. VDS Bio by kinegram.digital adds extra security and practicality to the VDS concept by enhancing it with biometric information: facial landmarks of the document or token holder.

The ICAO Data Structure for Barcodes (IDB) takes digital tokens to the next level. IDB is a definitive global standard for convenient, secure, and interoperable digital identity credentials. As advanced cryptographically encoded 2D barcodes, IDB elements offer the highest level of digital trust. They provide levels of security and sophistication that are comparable to those of physical identity credentials.

Differences between VDS and IDB for Identity Protection and Verification

VDS and IDB provide a practical path toward convenient, secure and interoperable digital identity credentials, with a slightly different setup and suitability for different use cases. Both 2D barcode solutions are extremely easy to issue and verify, and do not require any specialized issuance hardware or processes.

ICAO Data Structure for Barcodes

Asymmetric encryption of personalized identity data✓✓
Compatible with ICAO PKD participants (list), ICAO Master List and Health Master List standards✓✓
Easy personalization and issuance via a secure 2D code generator✓✓
Verifiable through individual check apps or government- or other official apps✓ – if corresponding public key was added✓
Inclusion of biometric data of the credential holder✓ – for VDS Bio by kinegram.digital✓
Multiple document/message types in one 2D barcode✕✓ – container approach, allowing to combine different data structures, e.g. MRZ and CAN
Inclusion of Signer Certificate within the 2D barcode✕optional
Issuer’s Signaturemandatoryoptional, allowing flexible use of IDB codes for pure data transmission scenarios
Individual Extensionslimited possibility via document type categoriestags 0x80-0xFF are explicitly reserved for national use
Compression of data for 2D barcode size reduction✕supports ZLIB compression for larger payloads
Coding of databinary, requiring compatible scannersbinary and Base 32 for improved compatibility, ensuring hassle-free, interoperable verification even with simple or older devices
Use Casesdocuments and environments necessitating robust identification and security, e.g.

  • insurance policies
  • medical prescriptions
  • employee badges
  • health certificates
  • event tickets
  • fishing licenses
documents and environments necessitating very high levels of assurance and security, e.g.

  • visa documents
  • travel permits, including emergency travel documents
  • arrival attestations
  • social security cards
  • residence permits
