Cryptography Will Revolutionize AI Data Privacy with Daniel Kang
Show notes
In this episode, Nathan sits down with Daniel Kang, Assistant Professor of Computer Science at the University of Illinois. Kang has done pioneering work bringing zero knowledge cryptographic proofs to AI. In this episode, they chat about the cryptographic theory behind Daniel's work, how cryptography allows us to balance the tradeoff between privacy and authenticity, and how cryptography usage is needed in a world where LLMs are increasingly embedded into our daily lives.
