Private blockchain is a term that refers to blockchain tech that does not divulge balances and transaction history without being a signing party to that transaction or without a delegated 'view' key created by the keyholder for the purposes of the audit. It's a confusing term which should have a better name, I agree. For an example, most cryptonote networks function this way unless they have explicitly damaged or disabled the functions responsible, like in the case of Electroneum.
