Description

User authentication method in broadcasting system {METHOD OF USER AUTHENTICATION IN BROADCASTING SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of paying a fee in satellite broadcasting, cable television, and video-on-demand (VOD), and more particularly, to a method of paying a fee by authenticating a user in such a broadcast system.

Channels operated by satellite broadcasting, cable television, and VOD can be largely divided into free channels and paid channels according to the pricing method. A free channel is a channel that anyone can watch without having to pay a subscription fee with only a receiver. In addition, paid channels that pay viewer fees may be divided into subscriber channels and pay per view channels. In this case, the subscriber channel means that if a subscriber subscribes to watch a program of one channel, he / she can watch all the programs of the channel, and the subscription fee refers to a channel received based on a certain period regardless of the program viewing time. In addition, the pay-per-view channel refers to a channel in which a viewer pays only for a program watched by a viewer.

In the paid channel, the data of the paid program is scrambled using a control word (CW) in order to prevent the viewer who does not pay the viewing fee. Therefore, the general viewer must first descramble the scrambled program data in order to watch the paid program. The scrambled program data is descrambled using the control word received from the smart card in the set-top box. The configuration of the conventional pay-TV system will be described with reference to the accompanying drawings.

1 is an exemplary diagram of a conventional pay broadcasting system configuration. The broadcast transmission system 100 may be composed of a broadcast transmission system 110 and a subscriber management center 120. The broadcast transmission system 110 transmits broadcast programs (for example, television video and audio, radio, etc.) and channel transmission schedule information provided by a program provider. The subscriber management center 120 manages subscribers' qualifications and billing information.

The set-top box 130 receives the broadcast signal transmitted from the broadcast transmission system 110, sends the entitlement control message to the smart card 140, and receives the control word if there is a viewing authority therefrom.

The smart card 140 decodes the entitlement control message and the entitlement management message, determines whether there is a viewing authority, and stores the viewing authority in the memory in the card and finally outputs the control word to the set-top box 130. The set top box 130 and the smart card 140 may exist in a plurality of subscribers' home equipment.

The pay broadcasting system 100 scrambles using a control word for each program in order to allow only a limited subscriber to watch pay broadcasting, and a descrambler (not shown) in the set-top box 130 is entitled to receive. Only in this case, the control word is input from the smart card 140 to be descrambled with the original program.

In addition, the subscriber management center 120 generates an Entitlement Management Message (EMM) and an Entitlement Control Message (ECM), and sets these messages in the set-top box of each home using the broadcast transmission system 110. 130 is transmitted to the smart card 140. The entitlement management message includes contents to which the subscriber is granted viewing rights (such as a list of payable views available for viewing), and the entitlement control message includes a series of paid program information including control words that can be scrambled.

These messages undergo several levels of encryption to ensure that only limited or authorized subscribers can receive the service, and the smart card 140, which receives the encrypted messages, decrypts these messages by an internal decryption algorithm and an internal processor. And, the qualification corresponding to each subscriber is stored in the memory of the smart card 140 to determine the subscriber's viewing eligibility and determine the decoding to the original signal of the program.

As such, if you have only a set-top box and a smart card, you can watch paid channels without any sanctions. The subscribers are given passwords individually, but the passwords can be set to simple numbers so that they can be easily exposed.

In addition, in recent years, the hacking incidents on set-top boxes have been frequently prevented, preventing the indiscriminate viewing of others and the viewing of others, and the broadcasting companies have been hit by profits from paid broadcasting.

Accordingly, an object of the present invention is to provide a method for paying a fee for paying broadcasting by reconfirming whether a user is a valid subscriber in a broadcasting system.

In order to achieve the above object, the present invention provides a user authentication method in a broadcasting system, in which a broadcaster authentication server receives a resident number of a subscriber of a broadcasting system and a telephone number of a mobile communication terminal that a subscriber inputs into a set-top box. In addition, the broadcaster authentication server transmits the received information to the mobile communication authentication server, the mobile communication authentication server to authenticate it and receive the result information.

Comparing the subscriber information included in the result information provided by the broadcaster certificate server with the self-registered subscriber information, and if there is a match, transmitting a message indicating that the authentication is successful to the mobile terminal through an SMS (Short Message Service) server; In addition, the subscriber information included in the result information provided by the broadcaster certificate server is compared with the self-registered subscriber information, and if there is a mismatch, a message indicating that authentication has failed is transmitted to the mobile communication terminal through the SMS server.

The transmitted authentication message is input to the set-top box by the subscriber, and the broadcaster authentication server authenticates the user by comparing the authentication message received from the set-top box with the authentication message transmitted to the mobile communication terminal through the SMS server.

In the user authentication method in the broadcasting system, the broadcaster authentication server receives the resident number and the mobile phone number of the broadcasting system subscriber entered into the set-top box from the set-top box, and the information received from the broadcaster authentication server. By comparing self-registered subscriber information, if there is a match, it transmits a message indicating successful authentication to the mobile communication terminal through SMS (Short Message Service) server, and the subscriber information included in the result information provided by the broadcaster certificate server and itself. The registered subscriber information is compared, and if there is a mismatch, a message indicating that authentication has failed is transmitted to the mobile communication terminal through the SMS server.

The transmitted authentication message is input to the set-top box by the subscriber, and includes a process of authenticating the user by comparing the authentication message received from the set-top box with the authentication message transmitted from the set-top box to the mobile communication terminal through the SMS server. It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, specific matters such as specific configurations are shown, which are provided to help a more general understanding of the present invention, and it is understood that such specific matters may be changed or modified within the scope of the present invention. It will be self-evident to those of ordinary knowledge.
