Abstract: A method may include storing, using a data management application on a user device, personal data that is associated with a user and a first data variable. The method may further include obtaining, from a requesting application and by the data management application, a data request for a second data variable. The method may further include determining, by the data management application, whether the first data variable associated with the personal data matches the second data variable associated with the data request. The method may further include transmitting, by the data management application and in response to determining that the first data variable matches the second data variable, the personal data to various intermediary nodes. One intermediary node among the intermediary nodes may transmit the personal data to the requesting application using a distributed ledger.
