Abstract: In one embodiment, a method of transmitting a directed query from a client device that stores private data elements includes determining relationships between elements of the private data, where each of the relationships associates two or more elements of the private data. The method may further include receiving a query related to a target element of the private data, where the query requests data related to the element that is not present in the private data. The method may further include storing the query in electronic memory. The method may further include determining a recipient for the query based on the relationships associated with the target element of the query. The method may further include electronically transmitting the query to the recipient.
