ELECTRONIC APPARATUS TO PREDICT PREFERENCE OF USER AND PROVIDE INFORMATION AND CONTROL METHOD THEREOF

摘要

An electronic apparatus is provided. The electronic apparatus includes, a communicator including communication circuitry, a storage, and at least one processor. The communication circuitry communicates with a plurality of user terminals and an external apparatus. The storage stores information of a plurality of users and a plurality of pieces of content. The at least one processor is configured to receive encrypted preference data of the user to first content from among the plurality of pieces of content from at least one among the plurality of user terminals through the communication circuitry, to transmit the encrypted preference data to the external apparatus, to receive characteristic data generated by applying an external operation and a re-encryption to the decrypted preference data from the external apparatus, to apply an internal operation to information of the plurality of users and the plurality of pieces of content through the received characteristic data, to predict a preference of the user to second content different from the first content based on the information subjected to the internal operation of the plurality of users and the plurality of pieces of content, and to provide the predicted preference information of the user to the second content. Thus, the operation may be performed efficiently and distributed with the external apparatus.
