Abstract
Systems for distributed controlled access to data stored across a plurality of sources are disclosed. A plurality of content providers maintain user databases. A first distributed database contains a master identifier for each user of each content provider. Stored in relation to the master identifier are the locations of the user's data in each of the content providers. A second distributed database comprises data identifying for each of the users, entities that are authorized to access the user's data. In response to a request from an entity, the second database is queried and, based upon access rights data, user's whose data the requesting entity may view are determined. The first distributed database is queried to determine for the identified user, the location of user data. The data is retrieved and stored at a location accessible by the entity. The second distributed database is updated to record the data access.
