The video discusses the concept of fully homomorphic encryption, its historical development, and its potential applications.

Summary

  • Artificial intelligence relies on big data, but privacy concerns are a significant barrier to leveraging AI for sensitive data.
  • Fully homomorphic encryption (FHE) enables the analysis of encrypted data without compromising privacy.
  • Craig Gentry developed the first practical FHE scheme in 2009, allowing computations on encrypted data to yield encrypted results.
  • While FHE is computationally intensive, specialized hardware is being developed by companies to make it more feasible.
