No, the point of FHE isn't that regular encryption is already compromised. It's that you can do processing on encrypted data while it's encrypted, without decrypting it. This opens up many more possibilities. For example, a cloud provider might store your data only in encrypted form and you can still do queries to pick out particular data or do some basic analysis, with the algorithm running on cloud computers, the result delivered to you in encrypted form, which you then decrypt with your private key.
The only problem is that there's a large performance penalty still, though there has been major progress in making it more efficient.
- yazzku 4y agoThe article does put quite a lot of emphasis on "soon broken" encryption algorithms, so can't blame kebman for that comment. It only mentions what you pointed out almost in passing. Also not an expert here, but if "Valuable insights through AI (artificial intelligence), big data, and analytics can be extracted from data", then you'd be a fool to believe this will protect your privacy, right? Or am I missing something? I want encryption that protects me from corporations, not encryption that protects the data corporations have from us and ups their surveillance game. I guess it's no coincidence a lot of research seems to be done by M$.
- not2b 4y agoIf FHE could be made to work (and we are a long way off), the cloud provider would not be able to see your data even though you're doing processing on the data that remains on the cloud provider's CPUs, so in that sense it would protect you from Amazon/Google/Microsoft/plug in your cloud provider here.
- yazzku 4y agoThen how can they extract "insights" from the data if they can't see the data? At what point do the "insights" defeat the purpose of protecting your data from the cloud provider? Or are the claims in the article bogus?
