We know governments and corporations maintain big databases about us. But we can’t verify the accuracy of it independently and privately. If the entities could be convinced to surely publish the records one at a time to logged in users, and with a mathematical nonce added to it – a private random string of characters unique to each record, and shared only with the person to whom it pertains, citizens could verify if the data is accurate.
New nonces can be added to the database as often as needed, so long as pulling down the new values was easy enough.
This way third parties could allow people to gather their nonce values in order to “see inside” the groups values across many systems. Perhaps that’s what this all about…
