Homomorphic encryption
An encryption technique that makes it possible to run calculations directly on encrypted data, without ever decrypting it: only the owner can read the result. It could allow sensitive data to be entrusted to a remote AI service without the service being able to see it, but for now it remains much slower than ordinary computing.
In other words
Handing a locked safe to a craftsman who works on its contents without ever being able to open it, then getting it back with the job done inside.

- What is the Cloud Act, and why hosting in Europe is not enough
The Cloud Act allows US authorities to demand data held by a company under their jurisdiction, wherever it is stored. We explain how the mechanism works and what to check.
- What is homomorphic encryption? Computing on data without ever reading it
Homomorphic encryption makes it possible to perform calculations on encrypted data without ever accessing it in plaintext. We explain the principle, its current limitations, and what it could change for AI and privacy.
