The system includes a plurality of nodes configured to el maintain a distributed database containing consumer privacy information having a plurality of entries. Each entry of the plurality of 'En entries in the distributed database is (i) encrypted with a unique encryption key associated with a consumer and the distributed database, and (ii) indexed based on a public encryption key associated with the consumer. A most recent entry associated with the consumer includes current personal information about the consumer. A first entry associated with the consumer includes an encrypted version 0 of the unique encryption key.
