Systems and methods for data distillation

A method comprising:

• determining that a database comprises a first record associated with an anonymized hash of an identifier of a user, wherein the first record comprises first data associated with the user;
• causing, based on receiving a message comprising the anonymized hash and second data, a second record to replace the first record, wherein the second record comprises the first data, the second data, and the anonymized hash;
• receiving, from a computing device, a request, wherein the request comprises the anonymized hash;
• and
• sending, to the computing device, a response to the request, wherein the response is based at least in part on the first data and the second data, and wherein the computing device is configured to send, based on the response and to the user, a targeted advertisement.

A method comprising:

• receiving, from a first computing device, a query associated with an anonymized hash, wherein the anonymized hash is associated with an identifier of a user;
• determining that a database comprises a first record associated with the anonymized hash, wherein the first record comprises first data associated with the user;
• receiving, from a second computing device, an answer to the query;
• causing a second record to be created, wherein the second record comprises the first data associated with the user, the answer to the query, and the anonymized hash;
• causing replacing, on the database, the first record with the second record;
• and
• sending, to the first computing device, the answer to the query.
