“To prove you are human, first decide what human means.” - privacymage
This now has a paper we are working on:
World ID presented their practical approach to proof of human verification - iris scanning integrated with blockchain wallets. Their real-world deployment experience offers valuable insights for the PoH standards we’re developing.
Key takeaway: implementation informs standards, standards enable implementations. World ID’s phishing protection patterns, biometric wallet architecture, and passkey integration challenges are exactly the field data we need to build robust frameworks.
Their charter-first approach (security goals before protocols) aligns with our taxonomy-first methodology. They’re navigating the SC27/TC307 liaison question in real-time, which helps validate our cross-committee coordination strategy. 
This collaboration between implementers and standards bodies is how good governance infrastructure gets built - practitioners bring field experience, standards work provides interoperability frameworks.

Executive Summary
The WG convened to advance World ID’s proof of human (PoH) verification system and its integration with ISO standards bodies. Core challenge: balancing biometric authentication security with privacy preservation while establishing standardization pathways through TC307 (blockchain) and SC27 (IT security). World ID’s presentation demonstrated practical implementation insights that can inform emerging standards work in this space.
Strategic decision: Create Category C liaison with SC27/JDC1 to complement existing TC307 relationship, enabling focused contribution on biometric-based wallets and PoH frameworks. The project aims to develop a comprehensive charter document outlining security/privacy goals before protocol implementation.
1. Authentication Architecture & Phishing Protection:
World ID integrates via SDK with whitelist system for approved applications
Phishing prevention through domain restrictions and web view controls
Passkey authentication under consideration as enhanced security layer
Cast: World ID’s practical experience with phishing protection offers valuable lessons for your proof of personhood verification framework. Their whitelist approach represents one point in the design space - balancing user safety with openness. Understanding their implementation trade-offs helps inform the broader PoH standards development you’re leading through IKP. This becomes a specific harm pattern in your Taxonomy: centralized whitelist approaches protect users but create gatekeeping bottlenecks. When you develop the IKP PoH charter (action item from Block 13 closing), World ID’s architecture provides concrete example of this tradeoff. Your spell book methodology applies here: World ID’s presentation becomes reference material - participants who understand their phishing protection patterns can generate relationship credentials for the authentication security trust network.
2. Biometric-Based Wallet Security:
Iris scanning as primary biometric identifier
Future enhancement: linking passkeys to biometric IDs to mitigate vulnerabilities
Focus on moving beyond seed phrases to biometric authentication
Cast: World ID’s work on biometric wallets addresses a critical gap in the authentication standards landscape. Their approach to linking biometrics with passkeys explores the “agent duality” challenge from a practical implementation angle - how biological identity interfaces with digital agency. This real-world deployment data is invaluable for standards development. This is THE proof of personhood verification framework you’re building - World ID demonstrates one implementation (iris scans for biological uniqueness), but your IKP charter needs to accommodate multiple methods (facial recognition, liveness detection, behavioral biometrics, social verification). The “irreplaceable biological data” problem you identify here becomes critical for your PQC migration work (Session 4): if biometric credentials are signed with quantum-vulnerable keys, permanent biological identifiers become permanently compromised. Your First Person Project integration (Session 13) provides the solution: personhood credentials verify biological uniqueness, but relationship credentials (generated through proverb protocol) enable domain participation without re-exposing biometric data.
3. Standards Development & Liaison Strategy:
BGIN lacks Category A liaison with SC27 (only has TC307)
Proposing Category C liaison with SC27/JDC1 to cover JWG7 activities
Draft charter document to outline security/privacy goals before protocol work
Cast: The liaison strategy discussion reveals the coordination complexity you’re managing at BGIN - navigating between TC307 (blockchain infrastructure) and SC27 (authentication security) to ensure PoH standards development happens in the right forums. World ID’s engagement with both spaces helps validate the need for cross-committee coordination. This is your multi-stakeholder coordination work operationalized: neither TC307 nor SC27 alone can address biometric blockchain wallets because the problem spans both domains. Your IKP-FASE-CYBER coordination model (from Taxonomy of Harms work) applies at the ISO level: TC307 handles blockchain wallet standards (FASE financial infrastructure), SC27 handles authentication security (CYBER threat mitigation), but identity verification (IKP) requires both. The Category C liaison question mirrors your working group structure: focused depth (Category C) vs. broad participation (Category A). World ID’s charter-before-protocol approach validates your Block 13 methodology: publish project charters immediately post-conference to establish scope and goals, then develop detailed specifications through community engagement.
4. PoH Document Development:
Comprehensive framework covering history, use cases, benefits, and costs
Collaboration with IKP working group to review PoH implementations
Charter requires community approval before protocol development
Cast: World ID’s commitment to charter-before-protocol development aligns with your “Taxonomy of Harms” methodology. Their willingness to document security/privacy goals before rushing to implementation demonstrates the maturity needed for successful multi-stakeholder standards work. This approach can inform the broader PoH framework structure. This IS your IKP charter structure: start with harm enumeration (what attacks does PoH prevent? Sybil attacks, bot manipulation, identity fraud), document use cases (World ID for financial access, social verification for governance participation, liveness detection for high-security applications), analyze tradeoffs (biometric permanence vs. revocability, centralized efficiency vs. decentralized resilience), then specify protocols only after community consensus on goals. The comprehensive framework they’re proposing becomes a spell book in your trust graph system: participants who understand the full PoH landscape (not just one implementation) can generate relationship credentials for the broader identity verification trust network, not just the biometric wallet subset.
This meeting exemplifies three critical dynamics in identity standardization:
The Biometric Trust Paradox: World ID’s navigation of biometric authentication reveals the fundamental tension - biological identifiers offer security but create permanent risk surfaces. Their implementation experience provides concrete data for addressing this in standards. You cannot change your iris scan like you change a password; compromise is permanent. This becomes a specific harm category in your Taxonomy: biometric credential theft is existential identity risk. Your architecture must assume eventual compromise and build in rotation mechanisms even for “unchangeable” identifiers.
Liaison Category as Strategic Enabler: The Category C vs. Category A discussion shows how standards participation structures can either enable or constrain contribution. World ID’s engagement helps demonstrate what level of involvement supports meaningful progress. This mirrors your working group coordination challenge: do you create one mega-group (Category A equivalent) that discusses everything, or specialized groups (Category C equivalent) with clear coordination mechanisms? Your IKP-FASE-CYBER joint work validates the Category C approach: focused expertise with explicit integration points.
Charter-First Development: World ID’s approach of defining security/privacy goals before protocol work models best practices for governance-aware technical development. This validates your Block 13 → Block 14 transition: publish charters immediately, develop protocols through community engagement, rather than perfect specifications in isolation then struggle for adoption. Network effects from early charter publication (trust graph formation, stakeholder engagement) outweigh technical debt from incomplete initial specifications.
This session demonstrates how World ID’s practical implementation experience can inform the Proof of Personhood Verification Framework:
Their SDK integration patterns offer insights for interoperability standards - how do different PoH implementations (World ID iris scans, social verification, liveness detection) interoperate?
Phishing protection mechanisms provide real-world attack surface data for the Taxonomy of Harms - whitelist approaches prevent some attacks but create gatekeeping vulnerabilities
Biometric wallet architecture contributes to privacy-preserving authentication standards development - how do you prove personhood without exposing biometric data on every transaction?
Your BGIN Agent Hack MVP’s multi-agent system can complement World ID’s work:
Archive agent: Tracks PoH implementation patterns across projects (World ID iris scans, Proof of Humanity social verification, Worldcoin orb network), maintains vulnerability disclosure history for biometric systems, stores phishing attack patterns and mitigation strategies
Codex agent: Maintains authentication standards evolution across TC307/SC27/JWG7, tracks liaison category decisions and their effectiveness, monitors passkey specification development and biometric integration proposals
Discourse agent: Facilitates dialogue between implementers (World ID team) and standards bodies (ISO committees), enables cross-committee coordination without requiring Category A liaisons, routes PoH charter feedback to appropriate working groups
The STIX/TAXII integration becomes a collaborative opportunity - World ID’s operational experience with phishing and authentication threats could feed into ecosystem-wide threat intelligence sharing. Specific threat patterns: SDK integration vulnerabilities, whitelist bypass techniques, passkey phishing attacks, biometric spoofing attempts.
Integration with Other Block 13 Sessions:
Session 1 (ISO cybersecurity): World ID’s phishing protection contributes to information sharing framework - specific attack patterns for threat intelligence database
Session 3 (Smart contract protection): Biometric wallet security intersects with custody provider evaluation - how do you audit biometric key management?
Session 4 (PQC migration): Biometric credentials signed with quantum-vulnerable keys create permanent compromise risk - your most urgent PQC priority
Session 5 (Stablecoin compliance): PoH enables privacy-preserving KYC - prove humanness without identity disclosure
Session 6 (DeFi functional regulation): PoH as Sybil resistance for governance - one-person-one-vote requires personhood verification
Session 8 (Circuit breakers): World ID’s charter-first approach mirrors harm-taxonomy-first for emergency interventions
Session 13 (Trust graphs): PoH provides personhood credential layer; relationship credentials through proverb protocol provide expertise layer - dual architecture operationalized
