Abstract
(EN)
Disclosed are an electronic apparatus, a server, and a method of controlling the same, the server including: a communicator configured to connect with an electronic apparatus and an external server; and a processor configured to: generate first encrypted information by encrypting first decryption information received from the electronic apparatus, the first decryption information for reproducing content, control the communicator to transmit, to the external server, the generated first encrypted information, generate second decryption information by decrypting second encrypted information received from the external server, the second encrypted information generated based on the first decryption information, and control the communicator transmit the generated second decryption information to the electronic apparatus to scramble the content by a scrambler of the electronic apparatus.
