E2E encryption means that only the person who stores the data should be able to read the data.

Having dealt with E2E encryption of data during transit and at rest, we now turn to the more esoteric case of E2E encryption of data during computation.

Advances over the last 10 years have resulted in systems that can indeed compute on encrypted data, i.e. without needing to see the data.

A second party can perform arbitrary computation on the data without seeing it.

FHE is designed so that the second computing party learns nothing about the underlying data, so we can say that FHE provides E2E encryption for data during computation, just as WhatsApp provides E2E encryption for data during transit.

As trust in such company's access to private data goes down, and yet the potential use-cases and benefits from technology such as artificial intelligence, blockchain, and personalized medicine increase, we need to find a way of unlocking the value in data without needing to make the data public.
