[0002]

2. Description of the Related Art In recent years, with the spread of the Internet, online shopping in which a terminal is connected to a server provided at a shop site on the Internet and shopping is carried out online via the terminal has become popular. .

[0003] When performing such online shopping, the UR of a shop site on the Internet is transmitted from a terminal.
The user logs in to the server by transmitting the L information, but when the user logs in to the server for the first time and performs shopping, the user transmits the URL information of the shop site from the terminal and connects to the server. By setting various information such as its own ID and password as initial setting information in the server via the terminal at the request of the server, the server is identified as the first customer. When such initial settings are completed, a purchase screen for the product distributed from the server side is displayed on the display unit of the terminal, and the user selects a desired product from the products displayed on the purchase screen. And buy.

[0004] When the first shopping is completed, the initial setting information set in the server is sent back to the terminal as cookie information (information for identifying a user) and set in the terminal. Therefore, when the user performs the second or subsequent shopping at the shop site using the terminal, the initial setting information set in the terminal is automatically transmitted to the server. in this case,
On the server side, the initial setting information is compared with the initial setting information set at the first login, and since both the initial setting information match, the terminal (that is, the user) is the server of the shop site for the first time. Since it is possible to identify that the terminal is not the terminal that has accessed, the user does not need to perform the initial setting again.

[0005]

When performing online shopping at a shop site on the Internet, when logging in to the server of the shop site for the first time, the user inputs his / her ID and password as initial setting information as described above. Must. Since such initial setting input operation is complicated, it is difficult for a user who is not familiar with a computer, and therefore, a device which can easily log in to a shop site server even for a person unfamiliar with a computer is demanded. ing.

Accordingly, the present invention provides a method for online shopping at a shop site on the Internet.
The purpose is to enable easy login to the server of the shop site.

And a sound control unit 18 for controlling output of a sound signal to the TV receiver 2.

In this system, a non-contact IC card (hereinafter, IC card) 4 is used, and the CPU of the terminal device is used.
An IC card controller 19 for reading and writing data from the IC card 4 is connected to the printer 11, and a printer controller 20 for controlling printing of the printer 5 and a serial port controller 21 are connected to the IC card controller 11. FIG.
FIG. 4 is a block diagram showing a configuration of a C card 4. The IC card 4 includes a CPU 41 and a memory 42 as shown in FIG.
And an antenna 43 including a radio unit.

This system uses a network server 8 provided by a user at a shop site on the Internet.
Is a system that allows the user to log in to the terminal device 1 and online shopping for the products of the shop site.
When a user performs such online shopping, the user applies his / her personal information in a registration application form.

FIG. 5 is a flow chart showing the data input status of such a registration application form. When a user performs online shopping at a shop site on the Internet, he / she writes his / her personal information in the registration application form as described above. This registration application form is passed to the operator on the provider side that provides the shop site, and the operator uses the registration terminal (not shown) to input the data written in the registration application form in step S1. Then, the input data is sent from the registration terminal to the network server 8, and the network server 8 creates cookie information according to the input data in step S2.

That is, based on the data written by the operator in the registration application form, “01234467” and “789012” are used as the user ID and password, respectively.
If the user inputs "34", the network server 8 sets the user ID "USERID" to "01234467" and the user password "PASS" as shown in FIG.
Cookie information including “78901234” as “WRD” is created and registered in itself. In FIG. 4, ww
"ABCD" of w. ABCD indicates the address of the shop site.

Here, when the IC card 4 is inserted into the network server 8, the network server 8 transmits the created cookie information (user ID, user password and shop site address) to the IC card 4 in step S3. The data is sent to the CPU 41 via the antenna 43, and is stored in the memory 42 by the CPU 41. Thus, the IC card 4 storing the cookie information including the user ID and the password is sent to the corresponding user in step S4.

The user accesses the network server 8 provided at a shop site on the network from his / her own terminal device 1 using the sent IC card 4, and performs online shopping at the shop site. FIG. 6 is a flowchart illustrating the online shopping operation of the terminal device 1. The operation of the main part of the present invention will be described based on this flowchart.

When a user logs in the terminal device 1 to a network server 8 provided at a shop site on the network and performs online shopping, the user inserts the IC card 4 sent to himself / herself into the terminal device 1. . Then, the insertion of the IC card 4 corresponds to the I
The CP of the terminal device 1 detected by the C card control unit 19
By being transmitted to U11, the CPU 11 determines "YES" for "insert card" in step S11. In this case, the CPU 11 reads the cookie information (cookie information A) stored in the flash memory 14 in step S12, and
The cookie information B stored in the IC card control unit 19 is read by the IC card control unit 19 to acquire the cookie information B in step S13.

Then, it is determined in step S14 whether the cookie information A in the flash memory 14 matches the cookie information B in the IC card 4. Here, if the user is the terminal device 1
Is used for the first time to access the network server 8 of the shop site, since the cookie information from the network server 8 side is not stored in the flash memory 14, the "cookie information A = cookie information B?" Is "NO". In this case, the CPU 11 erases the cookie information A in the flash memory 14 in step S15, and stores the cookie information B in the IC card 4 in the flash memory 14 in step S16.

Thereafter, when the user accesses the network server 8, the CPU 11
The cookie information B of the IC card 4 stored in the cookie information B is read in step S17, and the address of the server included in the cookie information B (that is, the address of the shop site (FIG. 4)
Is equivalent to the address of the accessed network server 8) in step S17.
Then, the user ID and the password included in the cookie information B are transmitted to the network server 8 via the modem 12 and the network control unit 13, thereby logging in to the network server 8.

After the terminal device 1 logs in to the network server 8 in this way, the CPU 11 sends the purchase screen of the shop site received from the network server 8 side to the image control section 17, and the image control section 17 causes the TV receiver 2 to receive the purchase screen.
To be displayed. The user performs online shopping for the product by selecting the product displayed on the purchase screen of the TV receiver 2 based on the operation of the remote controller 3 in step S18.

As described above, when accessing the server 8 of the shop site on the network for the first time, the user ID and the password stored as the cookie information in the IC card 4 are transmitted to the network server 8, so The user does not need to input and operate the initial setting information such as his ID and password and send it to the network server 8 side. Therefore, when the user logs in to the shop site on the Internet for the first time and performs online shopping, The complicated initial setting work can be omitted, and even a person unfamiliar with the computer can easily log in to the shop site and perform shopping. Further, the network server 8 can acquire user information such as a user ID and a password using a conventional means without using any special means.

In this way, when the user logs in to the server 8 of the shop site to perform shopping and the shopping is completed, the network server 8 uses the stored information including the user's ID and password as cookie information as the cookie information. Return to the side. CPU of terminal device 1
11 receives the cookie information and stores it as cookie information A in the flash memory 14.

After that, when the user logs in the terminal device 1 again to the server 8 of the same shop site and performs shopping, the user inserts his / her own IC card 4 into the terminal device 1, similarly to the “card” in step S 11. Is determined to be "YES", and in this case, the CPU 11 similarly obtains the cookie information A in the flash memory 14 in step S12, and also acquires the cookie information A in step S13.
To obtain the cookie information B. Then, step S14
Is determined in step S1 because the cookie information A and B match.
The determination of step 4 is “YES”, and the CPU 11 transmits the cookie information of either the IC card 4 or the flash memory 14 to the network server 8 in step S17, so that the terminal device 1 You are logged in. Thereafter, in step S18, a shopping process for a product based on the operation of the remote controller 3 by the user is performed.

When the user logs in the terminal device 1 to the server 8 of the same shop site again for shopping, the cookie information is sent from the server 8 at the time of the first shopping as described above. Since it is stored in the flash memory 14, the CPU 11 can transmit the cookie information A in the flash memory 14 to the network server 8, so that it is not necessary to access the IC card 4, and therefore, it is possible to log in promptly.

Here, if the above-mentioned user is a user a and another user other than the user a is a user b, the user b uses the terminal device 1 used by the user a. The terminal device 1 is connected to the server 8 of the same shop site as the user a.
, The user b inserts his / her IC card 4 into the terminal device 1 in the same manner. Then, similarly, the "insert card" of step S11 is determined to be "YES", and in this case, the CPU 11 similarly obtains the cookie information A of the flash memory 14 in step S12, and the cookie information of the IC card 4 in step S13. Get B. Then, in step S14, the cookie information A,
In this case, since the cookie information A is the cookie information of the user a and the cookie information B is the cookie information of the user b, the user IDs included in the cookie information A and B are determined. And the passwords do not match. Accordingly, the determination of “cookie information A = cookie information B?” In step S14 is “NO”. In this case, CP
U11 deletes the cookie information A in the flash memory 14 in step S15, and deletes the I information in step S16.
The cookie information B of the C card 4 is stored in the flash memory 14.

Thereafter, the user b sets the network server 8
When the CPU 11 is accessed, the CPU 11
In step S17, the cookie information of the IC card 4 of the user b stored in the cookie information is read out. If the server address included in the cookie information matches the address of the accessed network server 8, the cookie information is included in the cookie information. By transmitting the ID and password of the user b to the network server 8 via the modem 12 and the network control unit 13, the user b logs in to the network server.

In this way, the user “b” becomes the network server 8
When the user logs in to the terminal device 1, the CPU 11 of the terminal device 1 sends the purchase screen of the shop site received from the network server 8 side to the image control unit 17, and the image control unit 17
It is displayed on the V receiver 2. The user b selects the product displayed on the purchase screen of the TV receiver 2 based on the operation of the remote controller 3 in step S18, and performs online shopping for the product.

As described above, since the terminal device 1 is made to log in to the shop site based on the user ID and password of each IC card owned by each user, a plurality of users can share the same terminal device 1 with each other. It is possible to perform online shopping by using the service, and to prevent a certain user from impersonating another user and performing unauthorized online shopping.

In the present embodiment, an example has been described where online shopping is performed by logging in the terminal device 1 to the network server 8 provided at a shop site on the network. However, distribution is performed from a server provided on the network. The present invention can also be applied to a case where digital broadcast data is received and displayed. That is, the digital broadcast content is stored in the network server 8, the terminal device 1 logs in to the network server 8, receives the digital broadcast data including the image and audio distributed from the server 8, and displays the digital broadcast data on the TV video device 2. The same can be applied to such a system.
