A method and apparatus for displaying received data using a separate device that makes a user's receiving terminal, that has received only a unique code of data, transmit the unique code to a separate display device connected to the Internet, and which makes the display device access a server, in which the data is stored, and display the data corresponding to the unique code. The apparatus displays received data using a code generation unit for generating a first unique code that matches metadata received from a data server that stores the data and the metadata, a first communication unit for transmitting the first unique code to a receiving terminal, and a second communication unit for receiving a second unique code from a display device and transmitting the stored metadata that matches the first unique code to the display device if the first unique code corresponds to the second unique code.
