A car dealer wants to keep details about customer's car orders private, whilst recording evidence of the car order to reduce the possibility of them being refuted by any party.
The information is kept hidden, but the fingerprint is recorded on the blockchain and is publicly available. That means that anyone with the original car order details, typically the car dealer, the purchaser and the auditor, can verify the order content and timestamp. In the case of any dispute, that information can be shared with the moderator / mediator.
