As shown in FIG. 3, the transmission / reception module 150 of the user terminal 100 transmits a unique key value request signal including the user terminal ID to the authentication server 200 (S10), and unique to the authentication server 200. The key value generation module 210 generates a unique key value according to the unique key value request signal received through the transmission / reception module 250, and the storage module 230 stores the user terminal ID and the unique key value ( S20).

Thereafter, the transmit / receive module 250 of the authentication server 200 transmits the unique key value to the user terminal 100 (S30), and the encryption module 130 of the user terminal 100 uses the GPS module 110. The current location information of the received user terminal 100 and the unique key value received from the authentication server 200 are generated as an encrypted authentication key (S40).

The transmission and reception module 150 of the user terminal 100 transmits the encrypted authentication key to the authentication server 200 (S50), and the decryption module 220 of the authentication server 200 is received through the transmission and reception module 250. The encrypted authentication key is decrypted (S60).

Thereafter, the authentication determination module 240 of the authentication server 200 determines whether the authentication of the user terminal 100 is normal by comparing the decrypted authentication key with the authentication key stored in the storage module 230 (S70).

As a result of the determination in step S70, when the decrypted authentication key and the authentication key stored in the storage module 230 are the same, it is determined that the authentication is normal, and the transmission / reception module 250 of the authentication server 200 passes to the TPEG server 300. The current location information and the request data of the user terminal 100 is transmitted (S80).

Thereafter, the data setting module 320 of the TPEG server 300 searches for the region classification module 310 in which the TPEG data is classified by region, and the current position of the user terminal 100 received through the transmission / reception module 330. The TPEG data of the region is set according to the information, and the response data according to the request data is set (S90).

The transmission / reception module 330 of the TPEG server 300 transmits the set TPEG data and response data to the authentication server 200 (S100), and the transmission / reception module 250 of the authentication server 200 transmits the set TPEG data and response data. It receives and transmits to the user terminal 100 (S110).

The TPEG processing module 140 of the user terminal 100 processes to display the TPEG data and the response data received through the transmission and reception module 150 (S120).

As a result of the determination in step S70, when the decrypted authentication key and the authentication key stored in the storage module 230 are not the same, it is determined that authentication is impossible and the transmission / reception module 250 of the authentication server 200 determines that the user terminal 100 In step S130, the authentication key retransmission request signal is transmitted.
