Attestation of models and datasets (in-toto, Sigstore)
Attestation of models and datasets refers to the process of verifying the origin, integrity, and authenticity of machine learning models and datasets. Tools like in-toto and Sigstore provide cryptographic signatures and metadata, ensuring that models and datasets have not been tampered with and are from trusted sources. This helps establish a secure supply chain for AI, enabling users to trust the provenance and security of the components they utilize.

❓ Frequently Asked Questions
What is attestation of models and datasets?
Attestation is the process of proving the origin, integrity, and authenticity of ML models and datasets using cryptographic signatures and metadata so you can trust what you deploy.
What roles do in-toto and Sigstore play in attestation?
in-toto provides a structured framework for verifying a product’s supply chain with provenance attestations, while Sigstore offers signing, transparency logs, and verifiable signatures for artifacts like models and datasets.
How do attestations improve security and compliance in generative AI?
They provide verifiable provenance, detect tampering, support reproducibility, and enable governance and regulatory audits by offering evidence of origin and integrity.
What kinds of attestation artifacts are produced?
Digital signatures, provenance attestations, and metadata describing sources, steps taken, and checks performed (often including a software bill of materials for datasets).
