This creates a critical gap in AI Bill of Materials (AI-BOM) efforts: you can't hash a 'concept' baked into billions of floating-point weights. The piece explores three emerging defenses: (1) format sandboxing with .safetensors files and cryptographic signing to prevent code-execution attacks during model loading; (2) weight-space watermarking, which embeds a hidden statistical signature into model parameters during training to detect tampering or theft; and (3) zkML (zero-knowledge machine learning), which generates cryptographic proofs of correct training without exposing data, already used by Worldcoin for iris verification. zkML is currently too slow for most use cases but is viable for high-stakes domains like medical AI. The conclusion is that AI-BOMs must evolve into dynamic, mathematically embedded proofs of model lineage rather than static metadata files. ## Full article daily.dev links to this article rather than hosting it.
