Description
The present invention relates to a TPEG service system and a method thereof, and more particularly, based on the current location information of a user terminal and a unique key value according to a user terminal ID, to perform user authentication using an encrypted authentication key. The present invention relates to a TPEG service system and a method using location information of a user terminal to perform high authentication.
Recently, TPEG (Transport Protocol Expert Group) technology, which includes a message of a predetermined format in a digital multimedia brocasting (DMB) broadcast signal and transmits it, enables users who carry a DMB terminal to check traffic information and various contents. Standardization work is underway. That is, the TPEG service is an additional service that provides contents on roads, traffic, travel information, etc. together with the DMB broadcast. Currently, the TPEG service through the DMB broadcast has a limitation of a one-way service broadcast to a plurality of users.
Therefore, the current TPEG service provides uniform data to all users, and the processing burden of the user terminal is generated by repeatedly receiving the data once processed. In addition, by performing authentication through the authentication number only in the initial user terminal service, there is a problem that the reliability of authentication is lowered.
The present invention has been made in view of the above problems, and a first object of the present invention is to authenticate a user using an encrypted authentication key based on the current location information of the user terminal and a unique key value according to the user terminal ID. By doing this, more reliable authentication can be performed.
In addition, the second object of the present invention, by receiving only the TPEG data according to the current location information of the user terminal, to reduce the processing burden of the user terminal according to the repetitive data previously received, so that the user can receive only the desired regional services do.
In order to achieve this technical problem, the present invention relates to a TPEG service system using location information of a user terminal, and transmits a unique key value according to a user terminal ID by transmitting a unique key value request signal including the user terminal ID to an authentication server. Receives, generates an encrypted authentication key based on the current location information of the user terminal and the unique key value, and transmits the encrypted authentication key and the user's request data to the authentication server to the current location information of the user terminal A user terminal for receiving the TPEG data and the response data according to the request data; Receives a unique key value request signal from the user terminal and transmits the unique key value according to the user terminal ID, determines whether the authentication is normal by receiving and decrypting the encrypted authentication key from the user terminal, if authentication is normally performed An authentication server for transmitting the current location information and the request data of the user terminal to a TPEG server, receiving the response data according to the request data and the TPEG data based on the location information from the TPEG server, and transmitting the received TPEG data to the user terminal; And A TPEG server that sets TPEG data of a corresponding region and response data according to the request data based on the current location information of the user terminal received from the authentication server and transmits the response data to the authentication server; It includes.
The present invention relates to a TPEG service method using location information of a user terminal, the method comprising: (a) transmitting, by a user terminal, a unique key value request signal including a user terminal ID to an authentication server; (b) the authentication server generating a unique key value according to the unique key value request signal and storing a user terminal ID and a unique key value; (c) the authentication server transmitting the unique key value to a user terminal; (d) generating, by the user terminal, current location information of the user terminal and a unique key value received from the authentication server as an encrypted authentication key; (e) transmitting, by the user terminal, the encrypted authentication key to an authentication server; (f) decrypting the encrypted authentication key received by the authentication server; (g) determining whether the authentication of the user terminal is normal by comparing the authentication key decrypted by the authentication server with the authentication key stored in step (b); (h) If the decrypted authentication key and the stored authentication key are the same as the determination result of step (g), the authentication server determines that the authentication is normal and transmits the current location information and request data of the user terminal to the TPEG server. step; (i) the TPEG server searching for TPEG data classified by region, setting TPEG data of a region according to the current location information of the user terminal received, and setting response data according to the request data; And (j) transmitting, by the TPEG server, the TPEG data and response data set to the authentication server, receiving and transmitting the TPEG data and response data set by the authentication server to the user terminal. It includes.
According to the present invention as described above, based on the variable position information of the user terminal based on the location information and the unique key value according to the user terminal ID, by performing the user authentication using the encrypted authentication key to perform a more reliable authentication It can work.
In addition, according to the present invention, it is possible to reduce the processing burden of the user terminal according to the conventional repetitive data reception, and to receive only the service for each region desired by the user.
