Apparatus and method for recommending user privacy control

A user terminal, comprising:

• one or more processors that process computer executable program code embodied in non-transitory computer readable storage media, the computer executable program code comprising:
• common privacy control recommendation model acquisition program code that acquires a common privacy control recommendation model matching a result of privacy control preference of a user that is determined based on a result of a user answer to at least one question item;
• and
• privacy control recommendation generation program code that recommends a privacy control as an output of a common privacy control recommendation model that runs in response to a personal information request made to use a service,
• wherein the personal information request is delivered from a blockchain network that received the personal information request from a service provider which desires to provide a service to the user,
• wherein the blockchain network checks a user policy established by the user allowing for the personal information request to be transmitted only when a user policy designates that explicit approval of the user is required for use of the personal information,
• wherein the question item is a question item for which a difference between results of answers depending on the privacy control preference is equal to or greater than a predetermined value.
