Opinion by: Rob Viglione, co-founder and CEO of Horizen LabsCan you trust your AI to be unbiased? A recent research paper suggests it’s a little more complicated. Unfortunately, bias isn’t just a bug — it’s a persistent feature without proper cryptographic guardrails.A September 2024 study from Imperial College London shows how zero-knowledge proofs (ZKPs) can help companies verify that their machine learning (ML) models treat all demographic groups equally while still keeping model details and user data private. Zero-knowledge proofs are cryptographic methods that enable one party to prove to another that a statement is true without revealing any additional information beyond the statement’s validity. When defining “fairness,” however, we ...
