I used HE in my informatics b.sc. thesis to do privacy preserving surveillance: Store data on multiple servers and need server majority to reconstruct (non-HE), perform face recognition on encrypted data and then use (S?)HE to query a database if that face is in it - of course without the db learning about the content of the face data.
So, turns out just throwing some math on the problem works (I just applied some previous work; you know what they say about the shoulders of giants) and gives you the advantages of surveillance with less potential for abuse - but the necessary computational power is absurd :(
(And yeah, HE "noise" is a pain)
- x220 9y agoCare to share a link to your thesis?
- archi42 8y agoI have to dig it up I'm afraid, but I have it somewhere. Keep in mind it's only a bsc ;)

We did a some basic research on that for a seminar, and I wanted to figure out how far this can be pushed for a more "real life"-setting with the four roles mentioned in the introduction. I ran into slight time problems since the implementation was more difficult than I expected & due to some out-of-university-related stuff. Anyway, maybe things changed in the past 6 years and my conclusion from back than doesn't hold anymore. So this could be more feasible now. Let me know what you think ;-)
- no_identd 9y agoAnother interesting scenario for HE closely related to this one consists of accountability __without__ transparency. Which throws a wrench in the old concept of 'no accountability without transparency'.
