Abstract
A method and system for solving the technical problem of incompatibility between end-to-end encryption and artificial intelligence processing by transforming web browser architecture to enable secure AI operations without server-side decryption. The invention implements mandatory header validation (COOP/COEP/HSTS/Origin Isolation), WebAssembly sandboxing with dual-phase import control and signed attestation, bounded plaintext windows (T≤1000 ms) with automatic emergency wiping, and NIST SP 800-88 compliant multi-pass memory clearing with XOR verification. GPU acceleration with zero-copy transfer and mandatory clearing achieves practical performance. HMAC audit chains (H=HMAC_k(H∥ event ∥ nonce∥ timestamp)) provide regulatory compliance verification. Non-extractable keys bound to WebAuthn/FIDO2 ensure user control. The invention enables organizations to use advanced AI models (GPT-4, Claude, Gemini) with regulated data (HIPAA, PCI-DSS, GDPR) while maintaining full regulatory compliance through technical rather than contractual controls, eliminating the need for Business Associate Agreements in certain deployment models.
