In addition, with the popularization of smart phones, various hand-held personal devices are emerging. For example, devices having display means of various sizes such as a smart phone, a pad type terminal, a 7 inch tablet PC, and a 10 inch tablet PC are being released.

On the other hand, apart from the function of displaying only the received airwave or cable broadcasting signal, the interactive function with the user and various additional services using the Internet are provided on the TV. For example, smart TVs that support interworking with smart phones have recently appeared, including IPTV, which interacts with a PC or a server via an Internet connection. Examples of the above-mentioned smart TV include Apple TV and Google TV, and a conventional TV has a bidirectional communication function with the user and various additional functions using the Internet.

In addition, a device called a set top box (STB) is additionally required not only for TV but also for receiving digital broadcasting. The term "set-top box" refers to a device that is connected to a TV, receives signals from the outside, appropriately converts the signals, and displays the contents on a TV. A set-top box is a home communication terminal required to use a next-generation interactive multimedia communication service (video on demand (VOD), home shopping, network game, etc.) Also called a subscriber signal converter. It is connected to a network such as an interactive TV, a telephone, or a company's video transmission service (for example, a video dial tone provided by a US regional telephone company).

The set-top box communicates with a video server installed in a telephone company or a general cable broadcasting (CATV) station, and has a function of receiving and converting video signals with basic functions. In addition, various standards, such as having a telephone interface or a connection interface with a personal computer (PC), are also being examined so that data communication services such as telephone and PC communication can be simultaneously used. Accordingly, in order to preoccupy the interactive TV market, telecommunications, computer, and home appliance manufacturers are competing for the production and sale of set-top boxes.

The set-top box does not necessarily have a built-in tuner. An external signal may include an Ethernet cable, a satellite reception or terrestrial reception antenna, a coaxial cable, a telephone line, an analog Very High Frequency (VHF) UHF (Ultra High Frequency) antenna. The contents that can be obtained through this can be video, voice, internet web page, game, and the like.

As described above, the TV can provide not only broadcast information but also various information services through a set-top box interfaced with the Internet, and it is possible to select and control services through bidirectional communication with a user. In order to facilitate the inputting of a user's selection signal, there is a need for various functions of a remote controller to be expanded and a need for a convenient interface is required.

In addition, smart TVs with built-in functions of the set-top box can be connected to the Internet as well as watching terrestrial broadcasts, enabling computer functions such as video-on-demand (VoD), game, video call and application utilization. On the other hand, considering the fact that smart TV function can be utilized through the above-mentioned set-top box connection with a general TV, and a long replacement period of TV, smart TV and set-top box market coexist.

Meanwhile, in order to use the smart TV in cooperation with a user's portable terminal (e.g., a smart phone), a process of registering or authenticating the portable terminal with the smart TV is required. However, in general, in order to register or authenticate a mobile terminal with a smart TV, various inconveniences are incurred from the user's point of view, for example, the user directly enters information on the mobile terminal into the smart TV and performs a separate authentication process.

As a technique related to a method of authenticating a client terminal using such a separate user terminal, Korean Patent Registration No. 10-1025807 entitled " Authentication Method and Authentication Server (Literature 1) "(Document 1) A method of authenticating by scanning an image-type authentication key such as a QR code or the like through a separate authentication terminal is disclosed.

However, the above method discloses only the authentication method for the client terminal itself, but does not disclose a method for registering and authenticating a separate user terminal (e.g., a smart phone) on a client terminal (e.g., a smart TV).

In addition, when an application installed in the smart TV is intended to log in, the ID and the password of the user set for the application must be input one by one, which is inconvenient for the user.

Accordingly, there is a need for a method for effectively logging in an application installed on a smart TV through a smart phone and ensuring high security.
