Do you have a labeled version of this implementation?

or the idea for adding labeled mode?

Thanks.

Hi!

We do not have a public implementation for the labeled mode.

You can find more information for designing the labeled mode in Section 5 from this paper: https://eprint.iacr.org/2018/787.pdf The main idea is to have a "second database" on the server side, containing labels label on positions corresponding to their associated elements item from the server's database and to evaluate homomorphically (as in the implementation) (randomized versions of) polynomials that send item to label.

Hope this helps!
