Apple introduces homomorphic encryption via Swift. A cryptographic technique that enables computations to be done on encrypted data without revealing the underlying unencrypted data in th process. For example during cloud computations. In short, the building blocks of privacy-preserving technologies, techniques or protocols. But there's more! Private Information Retrieval protocols! This allows building a database and retrieving information in ways that is private: only the client knows what information has been requested. The databases does not know what information the client requested. Yet, the client gets the data. Why am I excited? I researched/used PIR ~15 years ago.
