Apple has announced the open-sourcing of its homomorphic encryption (HE) library, which is now available under the Apache 2.0 license. This library includes Swift libraries and executables, showcasing Apple's own implementation and a real-world application in iOS 18 for Live Caller ID Lookup. Homomorphic encryption allows computations on encrypted data without exposing the underlying data, enhancing privacy. Apple's implementation enables encrypted queries to a server for caller ID and spam blocking without revealing the phone number. The library utilizes the Brakerski-Fan-Vercauteren (BFV) scheme, which is quantum resistant. Experts in the field, such as Enveil's CEO, have praised Apple's move, highlighting the potential of HE to transform data usage across various sectors. The release comes amid increasing recognition of Privacy Enhancing Technologies (PETs) by global leaders, emphasizing the importance of secure data handling in a data-driven market. While the HE library provides foundational cryptographic components, experts note that developing a commercial-grade product requires significant additional work in software engineering and algorithm innovation.

Intro:
Homomorphic encryption (HE) is a cryptographic technique that enables computation on encrypted data without revealing the underlying unencrypted data to the operating process. It provides a means for clients to send encrypted data to a server, which operates on that encrypted data and returns a result that the client can decrypt. During the execution of the request, the server itself never decrypts the original data or even has access to the decryption key. Such an approach presents new opportunities for cloud services to operate while protecting the privacy and security of a user’s data, which is obviously highly attractive for many scenarios.Q: Does this mean that encrypted data (stored files, communications via messengers etc) can be scanned for keywords, without the need to decrypt the entire file/message?
If so, isn't this a huge privacy problem?
