However, the update checking unit 220 of the mobile terminal 200 may check whether the update is completed or not, and if it is stopped, the update checking unit 220 may determine whether the mobile terminal 200 is normally stopped.

For example, the update checking unit 200 of the portable terminal 200 may determine whether the portable terminal 200 is in a normal stop state, for example, by stopping by a user request, stopping by a battery consumption of the vehicle, If so, it can be judged as a normal stop.

However, if the update confirmation unit 200 of the portable terminal 200 determines that the vehicle is not in the normal stop state as a result of the determination of the normal stop state, it may consider the vehicle stop state as an abnormal stop and delete the vehicle software update information. This is what you need for security.

In one embodiment, when at least one of the stored vehicle identification information, the user identification information, and the terminal identification information is changed, the authentication information changing unit 230 of the portable terminal 200 transmits a change registration for the changed identification information to the content server 300 to the change authentication registration unit 330. [

Accordingly, the change authentication registration unit 330 of the content server 300 changes the corresponding data in response to the change registration request received from the mobile terminal 200, and transmits the result as response to the authentication information of the mobile terminal 200 To the changing unit 230. In this case, it is needless to say that the first authentication described above must be authenticated based on the changed data.

These communication module units 240 and 350 generally conform to a well-known wireless network connection standard.

As described above, the first software authentication program and the second software authentication program can be easily updated in the software update device 100 by using the portable terminal 200 having the security function and the relay role through the first authentication and the second authentication process.

Finally, the database 350 of the content server 300 stores vehicle identification information and user identification information at the time of service entry. The content server 300 described above includes an authentication performing unit 310, a program locking unit 320, And stores data processed by the authentication registration unit 330 and the communication module unit 340.

The database 350 is a concept including a computer-readable recording medium. The database 350 includes not only a consultation database but also a database in a broad sense including a data record based on a file system. Even a simple set of logs can be retrieved It is included in the scope of the database referred to in the present invention.
