No mechanism exists to retrospectively verify AI decision rationale. Accountability and audit requirements pose fundamental challenges
EU AI Act enforcement in 2026; rising ISO 42001 certification demand
- ZK proofs for AI decision attribution
- Permanent provenance for RAG sources
- Selective disclosure for compliance reports
AI Audit Log Proof
AI decisions in financial and public sectors lose their rationale when models are updated. EU AI Act and ISO 42001 demand explainable operations, but plaintext logs alone cannot prove decision immutability. Lemma attaches ZK proofs to AI decision attribution, preserving a structure where past decision rationale remains traceable even after model changes.
RAG Source Attestation
When an enterprise AI responds 'Based on Internal Policy Section X,' there is no guarantee the cited source matches the unaltered original. RAG indexes are rebuilt regularly, documents are versioned, and embeddings drift. Lemma proves that each citation in an AI response is cryptographically bound to the exact document version it claims to reference.
