For context, many companies already take preventative measures to protect user data and maintain differential privacy. Companies rarely store data on the cloud or in their databases in raw, unencrypted form. Therefore, even if attackers gain control of a company’s servers, they still have to bypass the encryption to read and access the data. However, data is not interesting when it’s just sitting there, encrypted and unused. When companies want to perform analyses on data to derive valuable insights, they have no great option but to decrypt the data to do this. When decrypted, the data becomes vulnerable. However, through end-to-end encryption, FHE becomes very useful as we no longer have to decrypt data to analyze it; this is just scratching the surface of what is possible.
