A lot of examples I read about zk try to obscure all data.

Is there any good reads on using zk to obscure only some data?

For instance, using zk to obscure on-device metadata such as location but the rest of the upload (such as a photo/video) is public?

You would encrypt certain facts and then use zk to prove that some property held up

Any use case is fine. Just trying to world build a little bit to apply it

Non financial use cases? Not really. All the ones I have in mind are financial or identity based.

Do you know any good examples where this is happening?
