Abstract: TECHNICAL DISCLOSURE — PRIVACY-PRESERVING IDENTITY FOR AI AGENTS AND DIGITAL COMMERCE Abstract As artificial intelligence evolves toward autonomous agents capable of contacting businesses, booking travel, exchanging messages, negotiating services, and executing payments, the protection of permanent personal identifiers is becoming a significant challenge for digital trust, privacy engineering, and secure AI-driven commerce. Each commercial interaction may expose telephone numbers, email addresses, payment identifiers, or other persistent identity information to external businesses, communication providers, and intermediary platforms. Existing technologies—including temporary phone numbers, masked email addresses, communication relays, payment tokenization, and consent-management systems—provide important privacy protections. However, a temporary identifier does not necessarily establish that every subsequent communication, transaction, or cross-border transfer remains authorized for the original session, recipient, jurisdiction, and purpose. This technical disclosure presents a proposed cryptographically enforced, session-scoped Virtual Identity (VI) and Compliance Jurisdiction Token (CJT) architecture, described in published international patent application PCT/IB2025/058743 (WO2025210622A2), for protecting personal identity during commercial communications and transactions. The architecture introduces a Virtual Identity Engine that substitutes permanent identifiers—including telephone numbers, email addresses, VoIP identities, messaging handles, and selected financial references—with session-specific pseudonymous identities. A Hybrid Virtual Identity (HVI) supports the protected association of multiple identifiers within a defined commercial interaction. Each VI or HVI is bound to a Compliance Jurisdiction Token (CJT) or Hybrid CJT (HCJT) containing session identity, validity, jurisdictional restrictions, authorization or consent evidence, and cryptographic anti-replay information. Protected identity-mapping and verification operations are performed within a Trusted Execution Environment (TEE) or Hardware Security Module (HSM). A Gateway Enforcement Module (GEM) verifies the relevant VI–CJT binding before permitting a controlled communication or transaction operation. Potential enforcement environments include SIP/VoIP gateways, WebRTC services, email relays, commercial messaging infrastructure, API gateways, financial transaction processors, and selected satellite communication systems. Signed revocation artifacts, session expiry, and tamper-evident audit records provide additional mechanisms for limiting unauthorized reuse and supporting independent verification. Further embodiments address advertiser-origin binding, isolation of commercial leads across businesses, virtual-number misuse, caller-ID spoofing, one-time callbacks, jurisdiction-aware data routing, Virtual Finance Cards, payment authorization, and financial compliance-related verification. European and International Research Relevance The architecture is relevant to research concerning trustworthy AI, privacy by design, digital sovereignty, pseudonymous identity, secure communication, consent management, and cross-border data governance. In a European context, the proposed mechanisms may support technical objectives associated with the General Data Protection Regulation (GDPR), particularly data minimization, purpose limitation, data protection by design, and international-transfer safeguards. The architecture may also be relevant to secure electronic communications, financial technology, and trusted digital-service infrastructure. Cryptographic validation of an authorization record does not independently establish the legal validity of consent or compliance with international data-transfer requirements. Regulatory applicability and compliance must be assessed separately. Big Tech Technical Relevance and Future Product Alignment The proposed architecture may complement existing product ecosystems associated with: Apple: Hide My Email, private communication relays, Apple Pay, and secure device infrastructure, through more granular session- and purpose-bound identity controls. Google: Gemini-powered business interactions, Google Ads, Google Voice, and Google Cloud, through protected commercial identities, advertiser-specific authorization, and controlled communication gateways. Meta: WhatsApp Business, Messenger, Facebook and Instagram Lead Ads, through session-specific customer-contact references that limit unauthorized cross-business reuse. OpenAI and Anthropic: ChatGPT agents, OpenAI Agents SDK, Claude, Claude Code, and MCP-connected services, through protected identities for agent-initiated messaging, bookings, external communications, and commercial transactions. Microsoft: Copilot, Azure Communication Services, Teams Phone, and enterprise data infrastructure, through cryptographically verifiable communication scope and jurisdiction-aware authorization. Amazon Web Services and Twilio: Protected identity processing, programmable communication services, masked contact systems, and verification APIs. Booking.com and other digital marketplaces: Session-bound guest or customer contact references that preserve legitimate commercial communication without routinely disclosing permanent personal identifiers. Visa, Mastercard, Stripe, and financial infrastructure providers: Virtual payment credentials, merchant-scoped authorization, and protected transaction-specific identity verification. Nokia, Qualcomm, and telecommunications operators: Protected communication gateways, trusted device processing, programmable network services, and potentially future AI-native 6G communication environments. These relationships represent potential technical integration opportunities, not confirmed company implementations or roadmap commitments. Scientific and Industrial Significance The central technical contribution is a proposed integration of ephemeral identity substitution, cryptographically bound authorization, protected verification, gateway-level enforcement, revocation, and verifiable audit evidence across heterogeneous digital communication and transaction systems. As AI agents increasingly interact with businesses on behalf of users, the architecture offers a potential mechanism for separating the authority to perform a specific task from unrestricted access to a person's permanent identity. Core principle: An AI agent may communicate, book, purchase, or transact on behalf of a user without automatically disclosing permanent identifiers or granting unlimited future contact authority. The disclosure offers a possible foundation for privacy-preserving agentic commerce, interoperable digital identity, secure communications, and jurisdiction-aware processing. Its technical performance, enforcement coverage, security advantages, and integration feasibility require independent experimental validation.
