The idea behind Homomorphic lib is to allow 2 basic operations (such as add, multiply) on encrypted numbers. They return encrypted numbers as well.
From those basic operations, we can build more complex functions.
That's the gist of the magic.
I'm all in until figuring out what to do with those operations. In this example, I think the scenario is straight forward. What do I do with adding or multiplying phone numbers? If I add phone numbers, what results should I expect and how do I use those post-decrypt?
I was under the impression here, that I hand you an encrypted phone number and you provide meta data back suggesting scam / known business / etc. Hence having trouble grasping how you can mathematically approach a phone number you wouldn't know to then change it.
I recognize the use-case, have you the service provide info/data back based on my query, and I don't want you to know I am receiving a call from said phone#. But what do I add to the phone number when querying you the service or what are you adding via FHE operations? Or why are you adding to the phone number that you can't know? What results from the addition when I'm decrypting, a longer phone number or additional results regarding the unknown phone number?
Separately, why would I provide this service two phone numbers to then multiply? I'm not sure the axis which would result, but the string I would expect is not a valid phone number and wouldn't result in my knowing more than before? Are there other technical aspects which cause add / multiply to be novel per implementation which isn't resulting in classical plaintext data actions?
