Embodiment Construction

[0026]Those skilled in the art understand that, as mentioned in the background technology, when the existing data query market performs data query, if the supplier and the demander have the same type of data (for example, the subject identifiers of the data owned by both parties are the same), then The operation of data query can be completed more conveniently, so as to obtain the value of the business type corresponding to the data owned by the other party. However, if the data query is directly conducted by both the supplier and the demander, after completing a query process, the supplier and the demander can easily infer the business type and corresponding value of the data owned by the other party, resulting in the leakage of user privacy.

Abstract

The invention relates to a multi data query system and method. The multi data query system and method comprises a demander terminal. The multidimensional data table to be queried is sent. The multidimensional data table comprises a first body indentifier of the query data, a dimension primary key and virtual sequence. The third-party terminal processes the received query multidimensional data table and sends the processed multidimensional data table. The processed multidimensional data table comprises a second body indentifier of the query data, the dimension primary key and the virtual sequence. The supplier terminal secondly processes the received query multidimensional data table and sends the multidimensional data table to the demander. The multi data query system and method does not have the same type of data to realize data query on the supply and demand both sides, better protect user privacy, avoid the relationship in the process of data query known by the body indentifier of the supply and demand and the main body of the third party.
