You have access to it. The communication terminal 1 includes a CPU and the like, and includes a signal processing unit 10 for controlling the following units, a modem, and executes a communication protocol such as TCP / 1P to access the Internet N2. Communication control unit 11, display unit 12 composed of liquid crystal display, CRT, etc., operation unit 13 composed of keyboard, pointing device such as mouse, etc., RAM, ROM, various types A storage unit 14 having a buffer 14 A, which is configured with a data base and temporarily stores the communication data received from the scanner 2, and a communication data transmitted via the transmission line L are serialized. And a communication receiver 15 for receiving data via the bus B. One of the scanners 2 has a CPU, a signal processing unit 20 having a decoder 2 OA for converting a two-dimensional code 3 read and scanned as image data into a predetermined character code string, and a two-dimensional code 3 as an image. An image camera 21 for reading and scanning as a whole, a light source 22 for irradiating light with a predetermined illuminance when reading and scanning the two-dimensional code 3, and a light source driver 23 for irradiating the light source 12 And operation for reading and scanning the two-dimensional code 3;! Sales switch 24, and a communication data transmitting unit 25 for transmitting communication data to the transmission line L through the serial bus B. Is provided.

The scanner is preferably a handy scanner or a pen-type scanner, but is not limited to them. The scanner 2 includes a CCD camera 21 as an image camera, a light source 22, and a light source driver 23, and a reading unit 26. When the two-dimensional code 3 is read and scanned, the reading unit 26 is used. 26 is brought close to the 2D code 3 and the reading switch 24 is operated.

4 is a card reader for reading such information from an IC card 5 storing a user's ID code and a decryption key. (If an active IC card including a CPU chip is used, a reader / reader is required.) This is added to the communication terminal 1.

Reference numeral 16 reads the ID code read by the IC card reader 4 and information necessary for decryption such as a key file, performs authentication, and executes a program for decrypting the two-dimensional code. Key information decryption unit.

When such a card reader 4 is used in addition to the communication terminal 1, the two-dimensional code 3 can be used in advance by performing an encryption process. In this case, the ID code previously assigned to the user is used. Or key information for decryption, and then perform authentication (such as adding a password if necessary) before decrypting the 2D code (eg, plain text, text, etc.). This is very effective in terms of security management.

When such a system is subjected to further encryption processing, when a signal is transmitted on a communication terminal or a communication network, the method disclosed in Japanese Patent Application Laid-Open No. No. 2 8 4 1 2 4, Japanese Patent Application Laid-Open No. 7-87070, Japanese Patent Application Laid-Open No. 9-167 72 0, Japanese Patent Application Laid-Open No. 10-285 853, and Japanese Patent Application No. Techniques such as those disclosed in US Pat. No. 2,964,900 can be adopted as appropriate to enhance security. Next, a specific use example and a basic operation example of the in-net one-point access system S will be described with reference to FIGS.

When a user is interested in product 4 and wants to know the details of product 4 when reading a printed material with 2D code 3 such as a computer catalog as shown in Fig. Move the reading unit 26 of the scanner 2 close to the code 3 and operate the reading switch 24 to read the two-dimensional code 3.

At this time, the two-dimensional code scanned and read by the 3 is a character string (for example, URL) indicating the communication address (here, URL) of the homepage on which the detailed information of the product is posted by the decoder 2 OA.

"Http: \ www.abc.ne.jp/") is converted to a character code string in which a terminal symbol (for example, a line feed symbol) is added, and the character code string thus converted is further converted to a communication data string. The transmission unit 25 transmits the communication data in a predetermined format to the communication terminal 1 via the transmission line L.

The communication terminal 1 that has received the communication data performs an operation as shown in steps 100 to 112 in FIG.

When the communication data is received from the scanner 2 via the transmission line L (100), the signal processing unit 10 temporarily stores the received communication data in the reception buffer 14A.

(101).

The signal processing section 10 reads out these character code strings stored in the reception buffer 14A, and determines whether or not the first character of the communication address, that is, the character string “http: 〃” is included therein (102 ).

If the character string “http: http” is present, the signal processing unit 10 determines whether there is a character code string indicating a terminal symbol (103). It is determined whether (browsing software) has been activated (104), and if the browser has not been activated, the browser is activated (105). If the browser has already been activated, reception continues. A character string indicating the communication address is extracted from the character code string read from the buffer 14A (107), and the extracted character code string is handed to the browser (108), and one of the homepages has already been opened. If so, refresh that screen.

In the browser to which the character code string indicating the communication address has been passed, for example, as shown in FIG. 4 (a), the character code string indicating the communication address is displayed in the address input / display field 12A of the screen 12 and displayed. Alternatively, the communication address may be checked and canceled if necessary (110). FIG. 4 (b) shows an example of a screen in which the home page specified by the two-dimensional code has risen.

Also, after the browser is started, a predetermined opening screen prepared in advance is displayed until the home page of the communication address included in the 2D code is displayed. You may make it.

Fig. 5 shows an example of the opening screen 1 2B.For example, displaying various types of advertisements and information to the user side by displaying the advertisement screen 1 2D using the waiting time Can be.

In Fig. 4 and Fig. 5, the communication address (here, "http: @ ww.abc.ne.jp") is displayed on the browser screen 12 and the opening screen 12B, and the communication address is correct. According to such a display method, if the display of the communication address is correct, and if a predetermined time (for example, 30 seconds) elapses (1 1 1), the signal processing unit 10 can be determined. Can automatically access the displayed communication address, and if the displayed communication address is not correct, the user can operate the pointing device such as a mouse on the operation unit 13 and operate the cancel button 1 2 C to cancel. it can.

If the cancel button 12C is operated (110), the signal processing unit 10 does not access this communication address and, for example, as shown in FIG. Display the screen 1 2 F that prompts for scanning, and waits for reading of the 2D code 3.

As shown in FIG. 7, such an in-net net bin point access system S may transmit communication data to the communication terminal 1 wirelessly.

Therefore, in FIG. 7, the photoelectric conversion units 25 A and 15 A are provided in each of the communication data transmission unit 25 of the scanner 2 and the communication data reception unit 15 of the communication terminal 1. The character code string converted by the decoder 2 OA of the scanner 2 is converted into an optical signal such as infrared light or ultraviolet light by the photoelectric conversion unit 25A and transmitted, and the photoelectric signal of the communication terminal 1 receiving the optical signal is transmitted. The conversion unit 15A converts the original character string.

Here, the scanner 2 is further provided with a buffer 27 and a transmission switch 28, and the two-dimensional code 3 read and scanned by the reading unit 26 is temporarily stored in the buffer 27, and the buffer 27 is stored in the buffer 27. After the data is stored in the communication data receiving unit 15, the transmission switch 28 is operated while the communication data transmitting unit 25 faces the communication data receiving unit 15, and the secondary data stored in the buffer 27 is stored. It is extremely convenient to transmit the original code to the communication terminal 1 in a form converted into an optical signal such as infrared light.

Reference numeral 6 denotes an ID card possessed by the user as necessary, and the ID card contains an ID code and a decryption key. In this case, the ID code may be a two-dimensional code, otherwise it may be a part of the bank's cash card, the number of the driver's license, other images identified by the user, Alternatively, a part of them may be read as key information by the scanner 2 and registered in advance, and the scanner 2 may perform a reading operation to perform authentication.

When using such a method, if the password for changing the key information can be specified in combination with any key information, the key information can be restored even if the key information is lost. Registration is easy.

In addition, since such a system can process only by reading key information with the scanner 2, additional equipment such as a card reader / card reader / writer is required compared to a system that uses an IC card. The structure can be simplified. In this figure, the key information as shown in FIG. 1 and the decryption unit 16 are not shown, but the authentication of the ID code and the decryption of the encryption are performed by the signal processing unit 10. Done.

As described above, when communicating signals on a communication terminal or a communication network, such a system is also disclosed in Japanese Patent Application Laid-Open Nos. Hei 6-284124, Hei 7-87078, and The techniques disclosed in Kaihei 9-1167220, JP-A-10-2851553, and JP-A-11-296490 enhance security Can be adopted as appropriate.

Also, when configuring such an internet-binpoint access system S, as shown in FIG. 8, the two-dimensional code 3 is printed using magnetic ink or the like, and the two-dimensional code 3 is printed. May be read by the reading unit 26 composed of a magnetic head.

Next, a specific usage example and a basic operation example of the Internet pinpoint access system S will be described with reference to FIGS. When a user is interested in Product 4 and wants to know the details of Product 4 when reading a printed material in which the two-dimensional code 3 is cut off, for example, a computer catalog as shown in FIG. The reading unit 26 of the scanner 2 is brought close to the dimension code 3 and the reading switch 24 is operated to read the two-dimensional code 3. Further, as shown in FIG. 9, if the decoder 1 OA is provided on the communication terminal 1 side as shown in FIG. Code 3 can be transmitted to communication terminal 1 as image data. In this case, the communication terminal 1 that has received the image data from the scanner 2 converts the received image data into a predetermined character code string by the decoder 1 OA, so that the scanner 2 can be made smaller and lighter. Become.

Here, in order to increase the speed of image data transmitted from the scanner 2 to the communication terminal 1, a USB (Universal Serial Bus) is used instead of the serial bus B for each of the scanner 2 and the communication terminal 1. The USB compatible cable L 'is connected to each USB.

In this system S, when receiving the image data of the two-dimensional code 3 from the scanner 2 as the communication data, the communication terminal 1 executes the processing shown in the flowchart of FIG. 10 (200 to 21 3). When the communication data is received from the scanner 2 as shown in the figure, the signal processing unit 10 temporarily stores the received communication data in the buffer 14A, and then reads out the stored communication data. The decoder 100A converts the communication address into a character code string in which a terminal symbol is added (see steps 200 to 202). Industrial applicability

As can be understood from the above description, in the Internet access method and system using the two-dimensional code of the present invention, the communication terminal can be obtained simply by scanning and selling the two-dimensional code with a scanner. The browser automatically starts the browser prepared in advance and can access the communication address specified by the two-dimensional code.

Further, the two-dimensional code used in the present invention is a simple method of adding a terminal symbol to a communication address. Because it has a simple structure, the amount of information of the two-dimensional code can be reduced and it can be made compact. Also, if the two-dimensional code is printed on a product catalog etc. corresponding to each page of the home page, You can access the home page that corresponds to the products and the point-to-point with pinpoint.

Furthermore, if the scanner is equipped with a character code string conversion function (decoding function), the contents of the two-dimensional code can be displayed and confirmed easily with a general-purpose communication terminal software (viewer), making it extremely convenient. It is.

If the scanner does not have a character code string conversion function and the communication terminal has a character code string conversion function, the scanner can be made smaller and lighter. Can be processed at high speed.

Furthermore, if the communication data transmitted from the scanner to the communication terminal is transmitted wirelessly by infrared or magnetic data, the signal line between the scanner and the communication terminal becomes unnecessary, which is more convenient. It is. In this case, if the communication terminal is connected to the Internet using a mobile phone or a PHS, it can be used both as a mobile gear and outdoors, which is even more convenient.

In addition, before the browser is started and the homepage specified by the two-dimensional code is opened, the prepared opening screen is automatically opened. Or, it can be linked to other interesting homepages, etc., and high value-added information can be provided.

In addition, the two-dimensional code is pre-encrypted and stored in an IC card or other card with information necessary for decryption. Unless such an IC card or other card exists, it becomes unnecessary. Since it is not used, unauthorized use can be prevented and security management is also beneficial.
