A global standard for verifying cultural heritage, craft provenance, and quality attributes of products — built on W3C DID Core, VC v2.0, GS1 Digital Link, and IETF SD-JWT VC.
Existing digital product passport frameworks were designed for industrial goods and environmental compliance. Cultural and quality products present fundamentally different verification challenges.
Cultural products, geographical indications, and intangible cultural heritage goods derive their value from craft heritage, regional identity, and tradition — attributes that standard industrial DPPs were never designed to capture.
DPP-CQ extends the digital product passport paradigm to encompass cultural value and quality dimensions, while maintaining full interoperability with the emerging global standards ecosystem, including W3C DID/VC, GS1 Digital Link, and EU EN 18xxx DPP standards.
Built on mature international standards, with architectural choices that address the specific verification needs of cultural and quality products.
A graduated carrier architecture aligned with EN 18220, providing options across cost and security requirements. All carriers resolve to the same credential format.
Progressive verification depth matched to the security requirements of each use case — from instant consumer scans to judicial-grade forensic verification.
Verify claims without exposing sensitive underlying data. Businesses can protect trade secrets and process details while enabling customers and regulators to verify authenticity.
Raw product data remains in its jurisdiction of origin. Only cryptographic hashes are registered on the global resolver network, enabling cross-border verification without data residency violations.
Version 2.0 introduces six major enhancements to expand interoperability, security, and compliance coverage.
Native support for GS1 Digital Link URIs, enabling seamless integration with existing GS1-based supply chain systems worldwide.
Aligned with EN 18220 data carrier requirements. Defines L1 (Open QR), L2 (SDM Secure NFC), and L3 (Tamper-evident NFC) tiers.
Supports both BBS+ (for selective disclosure / ZKP) and SD-JWT VC (IETF RFC 9529) credential formats, offering implementation flexibility.
Optional SM2/SM3/SM4 algorithm support for deployments requiring compliance with Chinese national cryptography standards.
Integrated carbon footprint data module aligned with ISO 14067, enabling environmental impact claims alongside cultural provenance.
Alignment with GB/T 47507-2026 and EU AI Act Art.50 for transparent AI-driven quality and authenticity assessments.
DPP-CQ (ICO Std 2001) is the flagship product standard within a broader four-layer digital trust standards framework.
DPP-CQ applies to any product whose value derives from cultural heritage, geographical origin, or craft quality.
Tea, grains, fruits, herbs, spices, and other products with designated origin status.
Ceramics, embroidery, lacquerware, woodwork, and other traditional craft products.
Bespoke garments and cultural apparel with verified craftsmanship provenance.
Artisanal food products, specialty beverages, and certified quality goods.
Handmade artifacts, cultural creative products, and limited-edition artworks.
Authorized reproductions and cultural merchandise from museum collections.
A phased approach from initial specification to a mature global standard with broad ecosystem adoption.
