A content providing server 3 for updating the multimedia contents with the connecting wireless terminal 9;

A wireless terminal that can be mounted or carried in a vehicle, comprising: a wireless terminal 9 for receiving and playing multimedia contents from a content providing server 3; In the automatic content update system of a wireless terminal using a USB storage device comprising a,

A storage device for storing terminal device information of the wireless terminal 9 and having a data storage space;

It has a program for automatic update, accesses the management server (2) when the storage device is connected, registers the terminal information stored in the storage device in the management server (2), and the member information provided from the management server (2). And a personal computer (1) for generating an encrypted certificate using the terminal device information and storing the encrypted certificate in the storage device, and receiving the content selected by the user's selection from the management server 2 and storing the content in the storage device; It further comprises a.

In the above configuration, the terminal device information is a unique device number of the wireless terminal 9, that is, a unique number. Since this unique number is assigned a different number for each wireless terminal 9, the unique number of the wireless terminal 9 is utilized to generate a certificate together with the user information (ID).

Meanwhile, the communication company server 2 has a function of authenticating a user as a management number provided through the PC 1 and providing the content providing server 3 while storing various multimedia contents. It has a function of checking whether payment has been made for the content.

The content providing server 3 provides multimedia contents while communicating with the wireless terminal 9 substantially. The download server 5 downloads and transmits multimedia data to the wireless terminal 9 via the wireless network. In addition, the DRM server 6 includes encryption information for copyright protection in the downloaded multimedia data so that the downloaded multimedia data can be prevented from being illegally copied and distributed to the general public rather than a legitimate user. 7) has a function of retrieving music data having the requested sound source and providing it to the wireless terminal 9 through the wireless communication network when a search music request is input from the wireless terminal 9.

2 is a view showing a wireless terminal applied to the present invention,

The wireless terminal 9 includes a wireless communication unit 10 for wireless communication, a USB interface 11 for connecting a USB memory 8, and a touch screen 12 capable of inputting control commands through an image output and a screen. ), A data storage unit 13 for storing various data, and a multimedia control module 14 for performing download and search music functions of the multimedia contents from the content providing server 3 and controlling the downloaded multimedia contents to be played back. And a control unit 15 for controlling the multimedia content to be played in association with the multimedia control module 14.

A portable storage device applied to the present invention is a USB memory 8.

Meanwhile, when the certificate is stored in the USB memory 8, the PC 1 checks the validity of the certificate and determines whether there is a right to update the content, and automatically updates the content according to the determined result.

The content updated by the PC 1 in the USB memory 8 is encrypted and stored, and the user's authority information about the stored content is also stored.

The wireless terminal 9 automatically updates new contents stored in the USB memory 8 when the USB memory 8 is connected.

 The wireless terminal 9 reads and decrypts the certificate stored in the USB memory 8 to check whether it matches the information of its own. If the result of the check determines that the certificate is valid, the content list information stored in the USB memory 8 is determined. After reading and classifying the content that needs to be updated, update the update target content.

Meanwhile, the operation of the present invention will be described with reference to FIGS. 3 to 7.

First, the terminal device information of the wireless terminal 9 is stored in the USB memory 8 to be used for automatic content update according to the flowchart of FIG. 3.

The wireless terminal 9 determines whether a certificate exists in the USB memory 8 connected to the USB interface 11, and if the certificate does not exist, stores its terminal device information in the USB memory 8.

As a result of the determination, if a certificate exists in the USB memory 8, the wireless terminal 9 determines the type and validity of the certificate. Do not store in (8).

4 is a flowchart showing a process of generating a certificate using the terminal device information stored in the USB memory (8).

As shown in FIG. 4, when the storage medium storing the terminal device information of the wireless terminal 9 is connected to the PC 1, the PC 1 checks the storage space of the USB memory 8. After performing the USB error check, the PC 1 transmits the terminal device information stored in the USB memory 8 to the management server 2 to request approval for the use of the terminal device.

As a result of the approval request, when the terminal device information and the member information (unique ID) are transmitted from the management server (2), the PC 1 uses the supplied terminal device information and member information to obtain a certificate for user and terminal authentication. It is generated and encrypted and stored in the USB memory (8).

If the certificate exists in the USB memory 8 connected to the PC 1, the PC 1 checks the validity of the certificate stored in the USB memory 8 to determine whether there is a right to update the content, and the result of the determination. If the certificate is valid, the certificate is used as is.

5 illustrates a process of automatically updating content using a certificate.

When a certificate is generated and stored in the USB memory 8 according to the flowchart shown in FIG. 4, the PC 1 requests a list of target contents to be updated to the management server 2 and is output on the screen of the PC 1. When the user selects the content information to be updated while viewing the content list, the PC 1 requests the management server 2 for the content selected by the user.

The management server 2, which has been requested to update the content, determines whether the user is authorized to use the content, and if the determination result indicates that the user has permission to use the content, the management server 2 sends the content to the PC 1; To be stored in the USB memory (8).

At this time, the content data stored in the USB memory 8 is composed of authentication information, content configuration information, content authority information, content data for the wireless terminal 9 and the user as shown in FIG.

The content configuration information is list information on content data stored in the USB memory 8, and content authority information is information on a user's usage period or the number of times of use of the content.

FIG. 6 shows a process of updating the content to the wireless terminal 9 by using the USB memory 8 in which the content is stored.

When the USB memory 8 whose contents have been updated is connected to the wireless terminal 9, the wireless terminal 9 reads and decrypts the certificate stored in the USB memory 8 to check whether it matches its information.

If it is determined that the certificate is valid, the content configuration information stored in the USB memory 8 is read to determine whether there is a required content, and if there is a corresponding content, it is updated.
