0000 Prior AI governance systems operate as isolated domain silos and cannot share hardware-attested evidence across domains, generate simultaneous multi-framework regulatory proofs, or allow regulators to independently verify compliance. The present invention introduces a Universal AI Governance Fabric, a horizontal platform that federates domain-specific Trusted Execution Environment (TEE) systems under a single cryptographically unified trust state anchored to silicon root-of-trust keys inaccessible to software. A heterogeneous TEE orchestration layer verifies attestations across multiple enclave technologies including Intel SGX, AMD SEV-SNP, Intel TDX, ARM TrustZone, and major confidential computing environments. When a threshold violation occurs, an atomic cross-domain transition orchestrator simultaneously destroys baseline session keys, increments hardware monotonic counters, and activates IOMMU isolation across participating systems. A Unified Regulatory Verification Engine generates jurisdiction-specific evidence packs for major regulatory frameworks from a single zero-knowledge proof computation, enabling independent regulator verification and providing a secure, cross-domain AI governance infrastructure.
Resumen de: US20260213950A1
0000 A system generates attested decision provenance records for artificial intelligence models. The AI model executes within a hardware-isolated enclave that prevents access or modification by external software. Before each execution, the system verifies that the correct model version is present by comparing a cryptographic model fingerprint and checking a hardware-anchored monotonic counter that prevents rollback to earlier versions. If a mismatch or rollback attempt occurs, execution is halted and the event is recorded. For each decision, the system produces a signed provenance token containing seven fields: a model hash, an input hash, a decision hash, an enclave measurement, a hardware timestamp, a version counter value, and an attestation signature covering all preceding fields. The token enables independent verification of the decision without revealing underlying data. Optional extensions include fairness evaluation, selective encryption, distributed fallback execution, post-quantum signatures, and automated compliance package generation.
