  The present invention relates to an information management method and an information management system in which content is transmitted and received between a server and a client in a network environment using a management symbol.

In recent years, digital information (contents) in various data formats has been handled with the progress of digitalization of input / output devices in accordance with technological progress due to an increase in computer processing speed and an increase in storage medium capacity. It was. For example, there have been increased opportunities for images (photos), audio, moving images, etc., which have been conventionally treated as analog information, to be treated as digital information.
In addition, with the advancement of communication technology, a network environment has been established in which such digital information can be easily transmitted and received. In addition, an internet connection function has been added to mobile devices such as mobile phones, and the opportunity to access digital information has greatly increased. Therefore, it has become possible to exchange information in various scenes without being restricted by temporal and geographical conditions.

However, while the environment for handling digital information has been established in this way, the operation of information equipment is still difficult for the majority of people. Therefore, the so-called digital divide between people who have the ability to handle information and those who do not have so-called digital divide is becoming a social problem. In particular, many middle-aged and elderly people feel resistance to keyboard input for giving instructions to information devices. Also, even for people with excellent information handling capabilities, mobile devices such as mobile phones are excellent in portability due to their small size, but it is particularly difficult to input long characters, etc. There is a problem that it takes time.

In recent years, along with the digital information is diversification that exists around us, the network environment has been developed. As a result, various usage methods have been used for contents. For example, content such as images on a network has been viewed from anywhere at any time using a portable terminal. In addition, by transferring and using content, it has been shared among a plurality of terminals. As described above, operations suitable for each content and operations customized for each user have been performed on content in various data formats.
In the method described in Patent Document 1, by restoring a predetermined URL from a two-dimensional code image, it is possible to access the predetermined URL from the Internet without inputting the address from a keyboard or the like. However, in this method, it is only used as a substitute for URL key input. That is, in Patent Document 1, only the effort of displaying a Web page is reduced, and the operation for each content or user is not automatically executed.
Currently, in order to change the operation according to the content, the user needs to instruct the operation every time. Therefore, it is desired to automatically execute these contents and operations for each user to reduce the load on the user.

The present invention has been made in view of the above points, and is an information management method and information management server using a management symbol for transmitting and receiving content between a server and a client in a network environment, It is an object of the present invention to provide an information management method and an information management server capable of automatically executing an operation corresponding to a purpose of use with respect to digital information (contents) in various data formats.

  An information management method according to claim 1 according to the present invention is an information management method for managing content composed of electronic data in a server connected to a network, wherein the server is a storage accessible from the server. Storing content in the region, setting an operation for the content using an operation type prepared according to the type of content, issuing a management symbol associated with the content, receiving from a client terminal Based on the information, the user who uses the client terminal and the content corresponding to the management symbol are specified, the operation for the content is determined by referring to the operation type, and the program on the server To automatically execute through processing, and to act on the content. , The content stored in the storage area, storing the private storage area of the identified said user, characterized by.

  An information management method according to a second aspect of the present invention is the information management method according to the first aspect, wherein the user customizes the content stored in a personal storage area as an operation on the content. It is characterized in that it is registered in a Web page to be used, and the registered content can be referred to as any one of a bookmark, an address book, and a Web album in the Web page.

Content handled by the present invention, still image information, moving image information, audio information, such as character information, may be directed to a plurality of types of digital information consisting of electronic data.
As still image information, for example, image data represented in a data format such as jpeg or bitmap can be considered. As the moving image information, for example, moving image data represented in a data format such as mpeg, wmv, or avi can be considered. As the audio information, for example, music data represented in a data format such as mp3 or wav can be considered.
As the text information, for example, text data represented in an arbitrary format such as an address such as a URL, information (address / name / phone number) written on a business card, personal memo, and the like can be considered. The text data is represented by a character code. As the character code, an EUC code, a ShiftJis code, a Unicode, or the like can be considered.

In addition to the above, information created by a specific application may be used. For example, data created by word processing software, data created by spreadsheet software, data created by schedule software, and the like can be considered.
Further, authentication information such as an ID and a password, encrypted information that is an encrypted bit string, an executable program, and the like are also conceivable.

The management symbol represents a bit string by changing the image pattern on the plane. In the present invention, an image of a management symbol is acquired by the imaging function of the client terminal, and the bit string is restored by analyzing the image.
The client terminal accesses the server via the network. At this time, it is preferable that the client terminal holds the address of the server in advance, and the program executes it with reference to it.
The accessed server specifies the content from the bit string and performs processing on the content. Through these operations, the content can be used from the client terminal via the network.

Administration symbol issues in relation to the storage address of the content, the content may be able to identify. The association between the management symbol and the storage address is preferably held in a storage area that can be referenced from the server via a bit string. The storage area that holds this association may be an area in its own server or an area managed by another server on the network.
The content storage address includes a URL corresponding to an address on the network, a file path indicating a folder in the server, and the like. Specifically, it may be configured with a server name, a port number, a folder name, a file name, and the like. The storage area for storing the content may be an area in the local server or an area managed by another server on the network.

The server of the present invention is preferably always connected to the network, and may execute a predetermined operation in response to a request from a client terminal with an imaging function that can be connected to the network.
The server can simultaneously manage a plurality of contents in response to requests from a plurality of users (client terminals).
Further, the server may perform all roles (issue of management symbols, operations on contents, etc.) by one server machine. Alternatively, a plurality of server machines may be prepared and these roles may be distributed. That is, the server of the present invention means a server system composed of one or more server machines that are always connected to a network.

Operation type defines the operation content to the content. When setting the action type, the user may select from the action types prepared in advance. In addition, a default operation type may be provided in advance, and it may be automatically selected if the user does not select it.
In the above description, it is preferable to prepare various types of digital information, and prepare operation types assumed for each type of digital information. At this time, a plurality of operation types may be prepared for digital information having the same data format. In this case, even if the data format is the same, another operation according to the purpose can be set.
In order to realize various operations, it is preferable to access various machines on the network from the server according to the operation details for the content. That is, in addition to access to the client terminal that images the management symbol, access to a storage area in the own server, access to another server, and the like can be considered.

The operation for the content may be realized on the client terminal by transmitting the content from the server to the client terminal.
For example, when the content is image data or moving image data, displaying the image on the display of the client terminal, playing the moving image, or the like can be considered. In addition, when the content is music data, it is conceivable to reproduce sound at the client terminal.
When the content is text data, for example, in the case of an address such as a URL, it is conceivable to access the address from a client terminal and display a WEB page. If the content is personal information (address / name / phone number), it may be added to the address book of the client terminal.
If the content is information created by a specific application, an operation corresponding to the application may be executed.

The content may be composed of a plurality of electronic data. In this case, it is preferable that a processing method for a plurality of electronic data is determined in advance, and the management symbols are read and then processed according to them. For example, when the content is made up of a plurality of image data, it is conceivable that each image data is displayed as an album in order on the display screen of the client terminal.
Also, different types of electronic data may be mixed in the content. For example, when music data and text data describing information related to music are included in the content, downloading the music data and displaying the text data at the same time can be considered. In the present invention, as in this example, different operations may be assigned to a plurality of electronic data.

The case where the operation | movement with respect to a content is implement | achieved in a server without transmitting to a client terminal is also considered. For example, when the server manages a personal page (so-called My page) on the network, it is conceivable to add a URL (text data) as content to a bookmark list prepared on this personal page.
At this time, content transmission to the client terminal may be combined with the above-described operation. For example, it is conceivable to add a URL, which is content, to a personal page on the server and simultaneously transmit it to the client terminal and display the WEB page with this URL on the client terminal.

The operation for the content may be realized by transmitting the content to another server. For example, it may be possible to add a URL to a personal page managed by another server.
Further, electronic data such as image data and music data may be transmitted to another server and stored in a storage area provided in this server.
Further, it is conceivable to send an ID or password as authentication information to a WEB site managed by another server and use it for authentication for accessing this site.
As described above, various functions such as information transmission and authentication can be obtained by accessing other servers.

In the above, the program on the server executes an operation corresponding to the operation type on the content. At that time, the operation affects the content, and the electronic data changes before and after the operation. That is, it involves movement, duplication, deletion, conversion, etc. of electronic data. Information (movement destination address, conversion method, etc.) necessary for executing the operation may be acquired by a program that executes the information.
For example, when the content is an address such as a URL, the program on the server determines whether to transmit to the client terminal or another server that manages the personal page according to the operation type, and executes it It is possible. Further, when music data is played back on the client terminal, it is conceivable to refer to other information that determines permission for transmission and execute transmission / stop based on the result.

In the above, a plurality of operations may exist for one operation type. In that case, the program may be executed by combining them.
For example, when image data or moving image data is reproduced on the client terminal, it is conceivable to transmit the content to the client terminal and convert the image size, arrangement, etc. to a predetermined format.

When utilizing the content on the client terminal, the client terminal may receive the operation type along with the content from the server. The client terminal holds a program in advance, and it is preferable to refer to the received operation type and execute an operation corresponding to the received operation type. At this time, it is preferable that the client terminal also holds a table regarding the operation type, and obtains information necessary for the operation with reference to this table.
Similarly, when content is transmitted to another server, the operation may be executed with reference to the operation type transmitted together with the content. Thus, by transmitting the operation type in the machine to access the servers to share operation type between machines, it is preferable to perform an operation corresponding to the purpose in each machine.

The personal storage area usually indicates a dedicated storage area for each user prepared on the server. This storage area only needs to exist on the network, and does not need to exist in the server that manages the content.
In general, user authentication is set in the personal storage area, and the personal storage area is accessed by inputting an ID and a password for identifying the user. If the storage area is managed by another server, the ID and password, by previously setting the user information table, automated input Then good.

The content includes image data, moving image data, music data, and the like. The user can store the content in the personal storage area by reading the management symbol issued by the content provider. At this time, the content may be transmitted to the client terminal at the same time.
Further, when the content is a URL (text data), bookmark registration may be performed on a personal Web page prepared in the storage area. In this case, the Web page specified by the URL may be displayed on the client terminal simultaneously with the bookmark registration.

  The information management server according to claim 3 according to the present invention is an information management server for managing transmission / reception of contents made up of electronic data, comprising management symbol issuing means for issuing management symbols, management symbols and contents Recording means for recording the association with the mobile terminal, user identification information acquisition means for acquiring the unique information for identifying the user of the mobile terminal from the mobile terminal, and management for acquiring the information of the management symbol imaged by the mobile terminal Content specifying means for specifying the content with reference to the association with the management symbol based on the information acquired by the symbol information acquiring means and the management symbol information acquiring means, and the operation type set for the content And an operation determining means for determining an operation on the content, and an operation on the content. The content stored in the di area, and having a content processing means for storing the private storage area of the user.

The content is stored from the servers to the accessible storage area. In this case, the storage area may be an area provided in its own server, or may access an area managed by another server via a network.
The management symbol issued by the management symbol issuing means may be output via the output means. As the output means, a known printing apparatus attached to the server or the client terminal can be considered. In this case, the management symbol is printed on a recording medium such as paper and output. Alternatively, the output means may be a display device provided in the client terminal. In this case, the data is displayed on the display device and output.
The management symbol output by the output unit may be captured using the imaging unit provided in the portable terminal, and information embedded in the management symbol may be restored from the captured image. This restoration may be executed on the portable terminal or the server.

  An information management server according to a fourth aspect of the present invention is an information management server for performing user authentication when logging in to a WEB site from a client terminal capable of being connected to a network, wherein access information from the client terminal is obtained. Access information acquisition means for acquiring, management symbol issuing means for issuing a management symbol, recording means for recording the association between the management symbol and the access information, and the management symbol issued by the management symbol issuing means Is transmitted on the display screen of the client terminal, the user identification information acquiring means for acquiring the unique information for identifying the user of the mobile terminal from the mobile terminal, and the mobile terminal. Management symbol information obtaining means for obtaining information on the management symbol, and the management symbol Association, and, on the basis of the unique information, and having an access specifying means for specifying the access from the client terminal.

  The client terminal that accesses the server may include output means for outputting the management symbol transmitted by the management symbol transmission means at the client terminal. As the output means, a display device provided in the client terminal is preferable. In this case, the data is displayed on the display device and output.

As a client terminal that accesses the server, a PC terminal using a PC (Personal Computer), a portable terminal, and the like can be considered. In this method, access from these terminals is identified and recorded in the server in association with the management symbol. As a result, the specific result good a terminal which has carried out the access.
For identification of access, session information recorded when the client terminal accesses the server may be used. As session information, a commonly used cookie may be used. By associating the cookie with the management symbol, a session with the client terminal can be secured.
Alternatively, for identification of access, the address of the client terminal, the unique number of the client terminal, the date and time of access, etc. can be used as information that can identify the client terminal.

The above configuration relates to user authentication when logging in to a predetermined WEB site from a client terminal. At that time, user authentication can be performed by acquiring user identification information registered in advance from a mobile terminal which is a terminal different from the client terminal. A PC terminal etc. can be considered as a client terminal.
The client terminal that accesses the server may include access means for accessing the server that manages the user authentication information. Or you may provide the access means to access the server which manages a WEB site.
A portable terminal that accesses the server includes a communication means for communicating with the server. This communication means may be mail transmission means and mail reception means on a portable terminal.

The access information acquired by the access information acquisition unit may be information that identifies access from a client terminal to a server that manages user authentication information. Or the information which identifies the access to the server which manages a WEB site may be sufficient. As this information, as described above, session information to the server may be used.
The server can identify the client terminal that performed access by acquiring the access information. Thereby, after user authentication is performed, it is preferable to permit login from the client terminal to the WEB site.

The user identification information is preferably a unique number of the mobile terminal. The user of the portable terminal may register the unique number of the portable terminal in advance in the server. In this case, an input by the user can be omitted by automatically acquiring the unique number from the memory of the mobile terminal.
However, the user identification information may be information that identifies a user who uses the mobile terminal, and may be an ID or a password input by the user. Further, a biometric authentication technique such as fingerprint authentication may be used. When the mail function is used for transmission / reception of information with the mobile terminal, the mail address of the user who is the sender may be used.

  In the above, the server that manages the WEB site is not limited to the case where it is operated by the same server as the server that manages information for user authentication or the same management entity. That is, the server that manages the WEB site and the server that manages the user authentication information may be different servers, or the management entities may be different.

  As mentioned above, it is preferable that the component of this invention is a program run on the computer generally used, ie, software. Further, dedicated hardware may be used, or a combination of software and hardware may be used.

According to the present invention, it is possible to automatically execute an operation according to a purpose by issuing a management symbol associated with an operation type. That is, it is possible to determine the various operations of each content upon decrypting the management symbol. The user can realize the operation only by an operation of imaging the management symbol with the portable terminal, and can use the content .
Further, the present invention has an effect of simplifying user authentication when logging in to the WEB site . That is, it is possible to perform reliable user authentication by a simple operation of imaging the management symbol with a mobile terminal.

Hereinafter, embodiments of the present invention will be described. An information management method according to the present embodiment and a schematic configuration diagram of the system are shown in FIG. In FIG. 1, a server 002, a registration terminal 001, and a portable terminal 003 are each connected to a network. In this embodiment, the two-dimensional code (color two-dimensional code 004, monochrome two-dimensional code 005) shown in FIG. 2 is used as the management symbol.
The server 002 has a function of always waiting for access from the registration terminal 001 and the portable terminal 003 through the network. In addition, the registration terminal 001 and the mobile terminal 003 have a function of accessing a server through a network, and the mobile terminal 003 further has an imaging function for capturing an image. The registration terminal 001 may be a PC that is generally used today, and the mobile terminal 003 may be a commonly used camera-equipped mobile phone.

In this embodiment, the content storage unit 110, the two-dimensional code issue unit 120, the two-dimensional code output unit 130, the two-dimensional code image acquisition unit 140, the two-dimensional code restoration unit 150, the storage address acquisition unit 160, and the operation determination unit 170 Configured (FIG. 3).
In the two-dimensional code issuing unit 120, the storage address of the content stored in the content storage unit 110 and the operation type for the content are registered in the database, and the number (record number) corresponding to the record in the database is converted into the two-dimensional code. Convert and issue. The two-dimensional code output unit 130 outputs the generated two-dimensional code by printing it on a sheet from a printing device such as a printer or displaying it on a display such as a computer terminal.
The two-dimensional code image acquisition unit 140 captures the output two-dimensional code with a camera-equipped mobile terminal and acquires an image. The two-dimensional code restoration unit 150 analyzes the acquired image and restores the record number embedded in the two-dimensional code. The storage address acquisition unit 160 refers to the storage address field in the corresponding record in the database from the restored record number and acquires the storage address of the content. Similar to the storage address acquisition unit, the operation determination unit 170 refers to the operation type field of the corresponding record in the database to determine the operation for the content.

  A two-dimensional code may be used as a management symbol. The two-dimensional code has a larger amount of information to be embedded than a conventional bar code, and targets a huge number of contents.
  The two-dimensional code is composed of cells arranged in a grid and positioning symbols. A data mark is marked on the cell, and a bit string is expressed by the way the data mark is displayed. For example, the presence / absence of a data mark may be expressed in correspondence with 1 and 0. Alternatively, in a color two-dimensional code, data marks of three primary colors (C, M, Y, or R, G, B) are used as color components, and they may be expressed by being superimposed.

  In the above, it is preferable to acquire the image data of the management symbol using an optical imaging device. By analyzing this image data using a computer, the display of each cell is identified, and the original bit string can be restored.
  The analysis of the image data may be performed on the server by transmitting the image data from the client terminal to the server. In this case, the analysis time is short because the processing capability is high as compared with the case of analysis by the client terminal. In this case, it is not necessary to place a unique application on the client terminal.
  The process of obtaining the record number from the restored bit string may be performed by the server. In this case, since the record number is not known to a third party, unauthorized access to the record can be avoided.

  The portable terminal that accesses the server may be provided with a mail transmission unit that transmits a mail to the server and a mail reception unit that receives a mail returned from the server. The mobile terminal may be provided with a content acquisition unit that acquires the content based on the received mail.
  A mail function prepared in advance in the mobile terminal may be used for transmission / reception of management symbols and contents. In this case, it is not necessary to prepare a plurality of applications according to different specifications for each mobile operator. In addition, since the mail function of the mobile terminal is widely used, the user does not need to learn or set a new usage method.

  The mail software of a portable terminal usually has a function of attaching a file to a mail document, and can use this to send and receive management symbol images and contents. In this case, the content may be transmitted and received as a file attached to the mail.
  If the content is text data, the content may be inserted into the mail document without being attached as a file. For example, when the content is a WEB address, it is assumed that the WEB address is described in a mail document, and the user designates and accesses this.
  The content may not be included in the mail from the server. That is, the storage address of the content may be described in the mail document, and the user may specify and download it. In this case, after receiving the mail, the user can determine acquisition of the content after referring to the tag.

  Data sets such as bit strings and address information related to a large number of contents are centrally managed by a server using a database. At that time, a database having a table format in which rows are records and columns are fields is used. That is, each record has a plurality of information recorded in the field.
  By using a database, it becomes possible to handle a large amount of content, and it is possible to process even if a large number of users access the server simultaneously. Furthermore, there is no waste in storing in the storage area, and resources can be used efficiently.
  By registering log information such as the date of access to a predetermined field and the user in the database, it becomes possible to manage the contents precisely.
  The database may be described in a general language such as SQL. In addition, it is preferable to use a generally popular application such as MySQL, PostgreSQL, or Oracle.

  In the above, content is assigned to a record, and one management symbol is associated. Also, it is preferable to assign a content storage address to one of the fields (storage address field). As a result, it is possible to specify the content from the management symbol.
  Records may be managed using the record numbers assigned sequentially in the order of records in the database. In this case, a desired record can be searched at high speed even if the number of records is enormous. This record number is preferably managed by a bit string represented by a binary string.

  In the above, it is preferable to prepare bit strings associated with all record numbers. The management symbol is associated with an arbitrary record by expressing this bit string. After reading the management symbol, the record number is restored from this bit string.
  The bit string here is the minimum unit of information handled by the computer, and represents information by a combination of 1 or 0 of each digit in the binary string.

  A database is used for associating the management symbol with the action type. Thereby, when registering the content, the operation type can be stored in a predetermined field (operation type field). Thereafter, the management symbol is decoded to identify the record in which the content is registered, and the operation type is acquired with reference to the field.

  In the above, since the operation type is managed on the server, it is possible to change the operation on the content even after the management symbol is issued. This change is preferably realized by changing the action type registered in the action type field using a predetermined program.
  For example, when music data, image data, and moving image data are targeted as contents, these data are transmitted to the client terminal within a certain period. On the other hand, when the time limit has passed, by changing the operation type, the transmission is stopped, and a text indicating the end of the transmission period is displayed.

In this embodiment, the record number of the database is expressed in a two-dimensional code through a plurality of conversions (FIG. 16). Hereinafter, the conversion will be described in detail by taking a specific numerical value for the number of bits and the like as an example.
In the database of this embodiment, the record number is represented by a 56-bit bit string, and at this time, the number of records of about 10 to the 16th power is prepared (D101).
An 8-bit redundant bit is added to this record number to form a 64-bit bit string. As redundant bits, 8 bits consisting of all 0s were added to the beginning of the record number (D102).
This bit string is encrypted by DES which is a common key encryption technique (D103).
An error correction code by the Reed-Solomon method is added to the encrypted bit string. At this time, a symbol which is a unit of error correction is composed of 4 bits (GF (2 ^ 4)), and 8 out of 12 symbols are used as a parity part (12, 4). As a result, the bit string becomes 192 bits (D104).
The bit string that has been subjected to error correction coding is expressed in a two-dimensional code based on a display rule that is not disclosed (D105).
As the two-dimensional code, a color two-dimensional code 004 is used in which each cell is displayed with data marks of color components of C, M, and Y superimposed. The number of cells is 10 × 10, and the total number of cells including positioning symbols is 100 cells.

In this embodiment, each time a two-dimensional code is issued, a plurality of modes are prepared so that display rules are different. The designated mode is recorded in 16-bit mode information (D106) and subjected to error correction coding processing (D107). Thereafter, it is displayed in an area different from the bit string of the two-dimensional code.
At that time, in order to obtain an error correction effect, the 4 bits constituting the symbol are made up of 4 cells adjacent to each other by the same color component.

The present inventors verified in the following numerical range and confirmed that a suitable effect was obtained.
The number of records prepared in the database is preferably 10 12 to 10 78 records. At this time, the record number may be represented by a bit string of 40 to 256 bits.
The redundant bits added to the record number may be about 10 to 600 bits including the error correction code. Also, the bits added as error correction codes are preferably 25 to 400% with respect to the bit string before being added. At this time, the bit string after adding the error correction code is preferably about 50 to 900 bits.
In the case of a color two-dimensional code, the display of the bit string is preferably about 16 to 300 cells in the data area. In the case of a monochrome two-dimensional code, the number of cells in the data area is preferably about 50 to 600 cells.
At this time, the total number of cells required for the two-dimensional code is preferably about 25 to 400 cells in the case of the color two-dimensional code including the area for positioning symbols and the like. In the case of a monochrome two-dimensional code, the number of cells is preferably about 64 to 676 cells.

The number of records used in the database should always be 10% or less with respect to the total number of records. This makes it easier to avoid unauthorized access from third parties and record specification errors.
Further, when reusing a record, a predetermined stop period may be provided for the record number from the end of use to the next use. In this example, a suspension period was provided for one year for temporary use and 20 years for normal use.

  In this embodiment, electronic data in various data formats using bit strings is targeted as content. That is, evaluation / verification is performed for electronic data such as text data of about 10 to 50 kilobytes, still image data / music data of about 5 to 10 megabytes, and moving picture data of about 500 to 5 gigabytes. It was.

  Hereinafter, details are individually described for a plurality of examples (Examples 1 to 6) that are different in usage in the present embodiment.

The first embodiment is an example in which a user (user A) who issues a two-dimensional code and provides content is different from a user (user B) who images the two-dimensional code and uses the content. In this embodiment, the user A who provides the content specifies in advance the operation details when the user B uses the content.
For example, when the user A who is an advertiser advertises his / her product, the URL is printed as a two-dimensional code on an advertising medium such as a flyer, and the user B who is a customer images the two-dimensional code so that the URL is displayed. To the web page. Thereby, detailed advertisement information is obtained or a product is purchased.
User A who gives a business card prints his personal information (name, address, phone number, e-mail address, etc.) as a two-dimensional code on his business card (FIG. 4), and user B who receives the business card prints it on the business card The personal information of the user A is registered in the address book in the mobile terminal by capturing the captured two-dimensional code. When the URL is included, the user A's home page may be browsed by accessing the URL.
Furthermore, a user A who publishes a photograph issues a plurality of image data as a two-dimensional code, and a user B who is a viewer images the two-dimensional code, thereby displaying a plurality of image data on the display screen of the portable terminal as an album. To do.
In addition, a user A who is a content provider uploads music, and a user B images and captures a two-dimensional code, thereby downloading and playing music data on a mobile terminal.

Hereinafter, the process until the two-dimensional code is issued will be described in detail with reference to a flowchart (FIG. 5).
S101: The server waits for access from the registered terminal.
S102: User A accesses a specific URL (Web page) of the server from the registration terminal.
S103: When there is an access from the registration terminal, the server returns an input screen (FIGS. 6 and 7) to the registration terminal.
S104: User A selects an operation type from the input screen, specifies content, and presses a send button.
S105: The registration terminal transmits the operation type selected from the input screen and the specified content to the server.
S106: The server that has received the content and the operation type stores the content in the storage. The storage address of the content is expressed, for example, as “/ data / rec0001 /”. If the content is a plurality of files, a plurality of files may be stored in the directory.
S107: The storage address of the content (in this case “/ data / rec0001 /”) is stored in the storage address field of an empty record in the database. The action type for the content is stored in the action type field of the same record.
S108: The record number of the record in which the storage address and the operation type are stored is converted into a bit string, and a two-dimensional code in which the bit string is embedded is issued.
S109: The issued two-dimensional code is returned to the registered terminal.
S110: User A who receives the two-dimensional code prints and outputs the two-dimensional code on a flyer, a business card, or the like.

  The communication protocol between the registration terminal and the server is not particularly limited. In this embodiment, it is realized by HTTP, S101 is realized by an http daemon (http service), and S102 and S103 are realized by an HTTP GET command and its response. The input screens in FIGS. 6 and 7 are described in HTML (and JAVA (registered trademark) script, etc.). S105 and S109 are realized by an HTTP POST command and its response, and S106 to S108 are realized by a server-side CGI program or a servlet.

In the database, as shown in FIG. 8, a number (record number) is assigned to each record, and a storage address field and an operation type field exist. In this embodiment, a preliminary information field is further prepared.
The record number is a number for designating the record, and the two-dimensional code is expressed corresponding to this number. FIG. 8 shows an example in which a decimal number is assigned for the sake of convenience, but a bit string using a binary string is preferable.
The storage address field stores the storage address (directory) of the storage storing the content.
The action type field stores an action type for determining how to process and operate the content. FIG. 9 shows examples of operation types and operation contents in this embodiment.
In the preliminary information field, information other than the content operation type, such as the registration date and the expiration date, is stored. In this embodiment, the spare information is written in a text file and stored in the storage, and the address is stored in the spare information field.

In S104, the input screen from the registration terminal includes a field for designating content, a button for selecting an action type, and a send button. When the user selects an action type, a field for inputting (or specifying) content is displayed accordingly. For example, when “Net Access” is selected as the operation type, a Web address input field is displayed (FIG. 6). When “album display” is selected as the operation type, an image data designation field is displayed (FIG. 7).
FIG. 6 shows an example of a Web address in which the content is text data, and the Web address that is the content is directly input from the input screen. In this example, “net access” is selected on the input screen, and after the user directly inputs the Web address, the transmission button is pressed. As a result, the operation type (net access) and the content (Web address) are sent to the server.
FIG. 7 shows an example in which the content is composed of a plurality of image data, and the user designates a storage folder for image data in the registered terminal from the “image data designation” column. In this example, “album display” is selected on the input screen, a save folder is designated, and then a transmission button is pressed. As a result, all the specified image data is extracted from the storage folder and sent to the server together with the operation type (album display).

  In the album display, a plurality of image data are received by the portable terminal, and those images are displayed on the display of the portable terminal. The user of the mobile terminal can view the displayed image. As a display method, after displaying a plurality of images as thumbnails, the image selected by the user may be enlarged and displayed. In addition, a plurality of images may be sequentially enlarged and displayed while switching the images at regular time intervals or for each user instruction.

  In the album display, when transmitting image data to the mobile terminal, it is preferable to perform processing suitable for the mobile terminal at the server. That is, it is preferable to convert the image size of the image data in accordance with the number of display pixels of the display of the portable terminal. In addition, the number of colors of the image data may be converted according to the number of colors displayed on the mobile terminal.
  In general, an image optimized for a mobile terminal has a smaller data capacity than an image captured by a digital camera or the like. In the present invention, before the image is transmitted, the image is converted by the server, so that the load on communication can be suppressed and the image data can be received quickly. Further, since the server has a high processing capability, it is possible to quickly display an image optimized for the mobile terminal.
  When displaying a plurality of images as thumbnails, it is preferable to create thumbnail thumbnail images on the server and transmit these images to the mobile terminal. In this case, by transmitting image data for enlarged display only to the selected image, the load on communication can be suppressed.

Hereinafter, a process from reading a two-dimensional code from a portable terminal to determining an operation on the content will be described using a flowchart (FIG. 10).
S201: The server is waiting for access from the mobile terminal.
S202: User B is a portable terminal with an imaging function, and images the two-dimensional code output in S110.
S203: Analyzing the two-dimensional code from the captured image data, and restoring the bit string embedded in the two-dimensional code.
S204: The restored bit string is transmitted to the server.
S205: Upon receiving the bit string, the server converts the bit string into a record number and searches the corresponding record in the database.
S206: The content storage address is extracted from the storage address field of the record, and the operation type is extracted from the operation type field.
S207: A process corresponding to the operation type is performed on the content.
S208: The content and operation type are transmitted to the mobile terminal.
S209: The received content and operation type are stored in the mobile terminal.
S210: The operation for the content is executed on the portable terminal.

In S204, the mobile terminal information is transmitted to the server simultaneously with the transmission of the record number. Here, the mobile terminal information includes the screen size of the mobile terminal, the type of audio codec that can be played back, and the like, and is used when content is converted on the server side in accordance with the mobile terminal.
In S207, the server processes the content. For example, when the operation type is “album display”, the mobile terminal information obtained in S204 is used to convert the image size to be suitable for display on the mobile terminal. If the operation type is “music playback”, the mobile terminal information obtained in S204 is converted into a music codec that can be played back on the mobile terminal.
In S210, processing is performed on the mobile terminal side. For example, if the operation type is “net access”, the URL is accessed. When the operation type is “address book registration”, the personal information is registered in the address book in the portable terminal. If the operation type is “album display”, a plurality of image data is displayed as an album using an application in the portable terminal.

In steps S202 to S204 and S209 to S210, an application of the mobile terminal is activated and a series of steps is performed. At this time, the URL of the server is embedded in advance in the memory of the portable terminal so that the application can automatically access the server.
In addition, the application transmits the mobile terminal information to the server in S204. The mobile terminal information may be input by the user, or the application may automatically acquire the information. This application is described in a program language corresponding to each mobile terminal.
The communication protocol between the mobile terminal and the server is not particularly limited. In this embodiment, it is realized by HTTP, and S204 and S208 are realized as an HTTP POST command and its response. S205 to S207 are realized by a CGI program or a servlet on the server side.

In the preliminary information field of the database, the address of the file in which the time information is recorded is stored. In the time information, a registered date and time (year / month / day), a valid period, etc. are set. At that time, the record is reused by releasing it after a certain time (valid period) has elapsed from the registered date and time. As time information, the date and time when the record is released may be recorded.
The effective period management is realized by a program on the server periodically accessing the database. This access is performed at a time interval of the minimum unit stored in the time information. For example, when the time information is composed of a year, a month, and a day, the minimum unit is the date, and access is made every day. In this way, the validity period is inspected.
Management of used records and unused records is performed by providing a list in which unused record numbers are recorded in the server. When releasing a record that has expired, the record number may be added to the list. Conversely, when issuing a two-dimensional code, the corresponding record number is deleted from the list.

In the first embodiment, the server that the registered terminal accesses, the server that stores the content, the server that holds the database, and the server that the portable terminal accesses are described as being the same, but they may be different servers. .
In Example 1, although the example which imaged a two-dimensional code with a portable terminal was described, the terminal which is not portable, such as a PC terminal, may be used instead of a portable terminal. In that case, another input device such as a scanner or a digital camera may be used, and image data may be acquired from this input device in S202.

In the second embodiment, as in the first embodiment, the user A who provides the content is different from the user B who uses the content. In the present embodiment, the user B himself / herself specifies in advance the operation details when using the content. This is realized by the user B registering in advance and setting the operation.
For example, when the content received by the user B is a URL (text data), in addition to accessing the URL from the mobile terminal (described in the first embodiment), the URL is stored in a personal storage area on the network, and the personal page Register a bookmark in.
Here, the personal page refers to a Web page that is customized by the user according to the purpose. The personal page is provided with a bookmark function and displays a list of Web addresses selected by the user.
In addition, when the content received by the user B is image data, the image data is stored in a personal storage area on the network in addition to being displayed on the mobile terminal (described in the first embodiment).

  In this embodiment, the processes (S101 to S110) until the two-dimensional code is issued are the same as those in the first embodiment.

  The user information table is a table in which information for identifying a user and information individually set for each user are recorded. As information for identifying the user, an ID or password for each user, a number unique to the client terminal used by the user, or the like can be considered. As the information set individually for each user, the operation content defined by the user, the address of the personal storage area, the authentication information for the storage area, and the like can be considered.
  In the above, the server accessed from the client terminal may identify the user by receiving the user ID, password, unique number of the client terminal, etc. from the client terminal. When a unique number is received and identified, there is an advantage that the user only has to register at the start of use and does not need to input an ID or password each time it is used.
  The content operation may be determined in advance in the user information table according to the type of digital information. Thereby, after reading the management symbol, the type of information can be determined, and the operation can be determined from the result by referring to the user information table. For example, when it is determined that the content is a URL, the URL is bookmarked on a personal page on the network.

  The type of information is preferably recorded for each content in a database held in the server and acquired by referring to the database.
  Alternatively, the data format may be acquired as the type of information from the extension attached to the file name of the content. For example, if the extension is jpg, the content is determined to be image information (jpg image data), and if the extension is mpg, the content is determined to be moving image information (mpeg moving image data).
  Further, the data format may be acquired by analyzing the content file. For example, the data format may be specified by analyzing the header information of the data. When the data format is text data, it is possible to specify the type of content such as URL and mail address by analyzing the character string of the text data.

Hereinafter, a process when the user sets an operation in the user information table will be described in detail with reference to a flowchart (FIG. 11). The operation setting is preferably performed before the two-dimensional code is issued. Also, once set, there is no need to do it every time.
S301: The server is waiting for access from the mobile terminal.
S302: User B accesses the URL of the server from the mobile terminal.
S303: After receiving access from the mobile terminal, the server returns a user registration screen to the mobile terminal.
S304: User B inputs the user ID and password from the user registration screen and transmits them to the server. At this time, the unique information (serial number) of the mobile terminal is transmitted simultaneously. Thus, the user ID and the password can be omitted by transmitting the unique information when accessing from the mobile terminal. Hereinafter, the user ID / password and the unique information of the mobile terminal are referred to as user identification information.
S305: Upon receiving the user identification information, the server searches the user information table and returns the operation setting screen (FIG. 12) of the corresponding user. If the user is not registered in the user information table, a user ID and password are newly registered in the user information table.
S306: User B selects an operation setting and sends it to the server.
S307: The server registers the received user operation setting in the user information table.

  In S301 to S304 of the present embodiment, the case where the setting of the user is performed from the mobile terminal is described.

FIG. 12 shows an input screen for setting the user action in S306. In the present embodiment, an operation that can be set by the user is registration of content in a personal page that is a personal storage area.
The content can be registered on the personal page by saving the content in a storage area on the network. For example, the URL can be viewed as a bookmark, the personal information can be viewed as an address book, and the image can be viewed as a Web album. If registered in a personal page, it can be referred to anytime and anywhere using a terminal such as a PC terminal or a portable terminal that can access the Web.
Information such as the address, ID, and password of the personal page necessary for accessing the personal page is recorded in advance in the user information table and obtained by referring to this.

FIG. 13 shows a user information table for registering user operation settings in S307. The user information table includes columns for recording a user ID, password, user area (user personal storage area), user operation settings, and remarks. In the user operation setting, a column is provided for each type of digital information. The numbers assigned to each column are “1” for Web address, “2” for personal information, “3” for image data, and “4” for Music data, “5” represents plain text.
In the user operation setting column, an operation setting number is assigned and an operation for content is set. When “0” is set in the corresponding column, only the basic operation is performed. When “1” is set, the basic operation and registration to the personal page are performed. When “2” is set, the basic operation and mail transmission to the designated address are performed. In addition, an operation setting number is prepared according to a combination of operations. When “9” is set, no operation is performed.
The user ID column and password column store an ID and password for identifying the user. The password field stores the encrypted password or the hash value of the password. The user area column stores the address of the personal page (in the case of the same server, a directory in the storage). In the remarks column, the mobile terminal specific information, the user expiration date, and the like are stored.

  The communication protocol between the client and server is not particularly limited. In this embodiment, this is realized by the HTTP protocol, S301 is realized by an HTTP daemon (http service), and S302 and S303 are realized by an HTTP GET command and its response. The user registration screen is described in HTML (and JAVA (registered trademark) script, etc.). When the registration completion screen is returned in S304 and S305, and in S306 and S307, it is realized as an HTTP POST command and its response, and S305 and S307 are realized by a server-side CGI program or a servlet.

Hereinafter, the process from reading the two-dimensional code from the mobile terminal to determining the operation for the content will be described using a flowchart (FIG. 14).
S401: Same as S201.
S402: Same as S202.
S403: Same as S203.
S404: The restored bit string and user identification information are transmitted to the server. Here, the user identification information refers to the user ID and password registered in S304. When the unique information of the portable terminal is registered in S304, the user B does not need to input the user ID and password.
S405: Same as S205.
S406: Same as S206.
S407: From the user identification information received in S405, the user is identified by referring to the user information table. If the passwords do not match, an error is returned to the mobile terminal and the authentication information is input again.
S408: A process corresponding to the user operation setting is performed on the content.
S409: Same as S208.
S410: Same as S209.
S411: Same as S210.

In step S408, the process for the content is determined with reference to the user operation setting column of the user information table.
For example, in the user information table of FIG. 13, for the user ID “abcdef”, the operation setting number “1” is set for the digital information type “1” (Web address). Therefore, when the content is a Web address, basic access to the Internet and bookmark registration to the personal page are performed. At this time, in bookmark registration, a file in which a URL is described is added to the bookmark directory (“/ usr / abcdef / bookmark /”) in the user area.
In the user ID “abcdef”, the operation setting number “1” is set in the type “2” (personal information) of the digital information. Therefore, when the content is personal information, basic address book registration (registration in a mobile terminal) and registration of a personal page in the address book are performed. At that time, personal information is added to the address book file (“/usr/abcdef/address.txt”) in the user area.
In the user ID “zzzz003”, the operation setting number “1” is set in the digital information type “3” (image data). Therefore, when the content is image data, album display on the portable terminal, which is a basic operation, and registration of image data in the album of the personal page are performed. At this time, the image data is stored in the image data area (/ usr / zzzz003 / image /) of the user area.

In this embodiment, it is also possible to select an operation for sending content from a server by mail. At that time, in S306, the user B designates a mail address from the input screen (FIG. 12). In S307, an operation setting number (for example, “2”) including mail transmission is set in the user operation setting field of the user information table. The e-mail address is recorded by providing a column of e-mail addresses in the remarks column.
For example, in the user information table of FIG. 13, for the user ID “zzzz003”, the operation setting number “2” is set for the digital information type “1” (Web address). For this reason, if the content is a Web address, in step S408, an email in which the content URL is described (or an email to which a text file in which the URL is attached) is transmitted.

  In this embodiment, the personal page is described on the assumption that it is a page managed by the same server or the same management entity as the server that holds the database. However, the present invention is not limited to this and is provided by other network service providers. A general personal page (so-called “My Page”) may be used.

  Since other description in the present embodiment is the same as that in the first embodiment, a description thereof will be omitted.

In the third embodiment, the user A who provides the content and the user B who uses the content are the same user. In the present embodiment, it is easy to transfer and share content in its own PC terminal to the mobile terminal.
For example, the image data stored in the PC terminal by the user is transferred to the portable terminal so that the user can view it at any time on the portable terminal. In addition, music data, data created by an application such as word processing software or spreadsheet software, and the like are transferred to the mobile terminal to be used on the mobile terminal.

As a specific procedure, the content in the PC terminal is uploaded from the PC terminal operated by the user to the server, and a two-dimensional code is returned from the server.
Thereafter, the two-dimensional code is displayed on the display of the PC terminal, and the two-dimensional code is captured by the camera-equipped mobile terminal (FIG. 15).
Two-dimensional code information (image data of a two-dimensional code in this embodiment) is transmitted from the portable terminal to the server. At this time, the mail function of the mobile terminal may be used.
The captured image of the two-dimensional code is analyzed to identify the content uploaded from the PC terminal.
Send the identified content to the mobile device.
Through the above operation, the content is transferred from the PC terminal to the portable terminal via the server.

  In the above example, as a procedure, after uploading the content to the server, the two-dimensional code is displayed on the PC terminal. On the contrary, an example of uploading the content after displaying the two-dimensional code is also considered. It is done. In this case, after deciding which record to use and issuing a two-dimensional code, it is preferable to register content for this record.

  In the present embodiment, the mail function of the mobile terminal is used when transmitting and receiving a two-dimensional code image and content between the mobile terminal and the server. The portable terminal captures the two-dimensional code using the camera function, attaches this image, and transmits it to the mail address of the server.

The server acquires a two-dimensional code image and the address of the mail sender from the sent mail. At that time, the server may be provided with a filtering process for deleting illegal mail. As this filtering process, in this embodiment, mails sent from other than the carrier are excluded. Further, in the present embodiment, those other than those having an appropriate format and size of the attached image file (format: JPEG, size: 10 Kbytes to 1 Mbyte) are excluded.
Thereafter, the acquired image of the two-dimensional code is analyzed to specify the content, and an operation corresponding to the operation type is executed. When sending content to a mobile terminal, it is sent to the email sender's address.
The mail replies from the server are given a mail title according to the action type. This makes it easier for the user to find a desired mail from the mail list. The type of digital information may be added as the mail title.

  A server with a mail server function was used. As the mail server function, SMTP (Simple Mail Transfer Protocol) and POP (Post Office Protocol) were used.

  Since other description in the present embodiment is the same as that in the first or second embodiment, a description thereof will be omitted.

As in the third embodiment, the fourth embodiment is an example in which the user A who provides the content and the user B who uses the content are the same user. In this embodiment, it is easy to transfer and share content in its own mobile terminal to a PC terminal.
For example, the user transfers the image data stored in the portable terminal to the PC terminal and uses it for browsing or editing on the PC terminal or taking a backup.

As a specific procedure, a server is accessed from a PC terminal operated by a user, and a two-dimensional code is returned from the server. At this time, the server acquires access identification information for identifying the access from the PC terminal and registers it in the database.
Thereafter, the two-dimensional code is displayed on the display of the PC terminal, and the two-dimensional code is captured by the camera-equipped mobile terminal.
Two-dimensional code information and contents in the portable terminal are uploaded from the portable terminal to the server. At this time, the mail function of the mobile terminal may be used.
The captured two-dimensional code image is analyzed to specify access from a PC terminal registered in the database.
The content uploaded from the mobile terminal is transmitted to the PC terminal whose access is specified.
Through the above operation, the content is transferred from the portable terminal to the PC terminal via the server.

  Since the other description in a present Example is the same as Examples 1-3, it abbreviate | omits.

In the fifth embodiment, as in the third and fourth embodiments, the user A who provides the content and the user B who uses the content are the same user. In the present embodiment, it is easily realized that the contents of its own PC terminal and portable terminal are synchronized and shared between these terminals.
For example, the address book and schedule held by the user on the PC terminal and the portable terminal are always used in the latest state in synchronization.

As a specific procedure, the content in the PC terminal is uploaded from the PC terminal operated by the user to the server, and a two-dimensional code is returned from the server. At this time, the server acquires access identification information for identifying the access from the PC terminal and registers it in the database.
Thereafter, the two-dimensional code is displayed on the display of the PC terminal, and the two-dimensional code is captured by the camera-equipped mobile terminal.
The server is accessed from the mobile terminal, and the two-dimensional code information and the content in the mobile terminal are uploaded. At the same time, the server acquires access identification information that identifies access from the mobile terminal.
The captured two-dimensional code image is analyzed to specify the access of the PC terminal registered in the database.
The server compares the content uploaded from each of the PC terminal and the portable terminal, and specifies the content with the new updated date and time.
Thereafter, the newer content is transmitted to the terminal holding the old content and replaced with the content in the terminal.
With the above operation, the contents are synchronized between the PC terminal and the portable terminal via the server.

  In the above example, the PC terminal and the mobile terminal each upload content to the server. However, only the content update date and time may be uploaded. In this case, after comparing the update date and time of both, only the content with the new update date and time can be uploaded to the server.

  Since the other description in a present Example is the same as Examples 1-4, it abbreviate | omits.

Example 6 is an example when the user who operates a PC terminal and the user who owns a portable terminal are the same user. In this embodiment, it is possible to log in to a website from a PC terminal without the user inputting user authentication information.
For example, login from a PC terminal to a website that requires user authentication, such as a bank account, is realized by imaging a two-dimensional code displayed on the PC terminal with a mobile terminal owned by the user. Thereby, the input of ID and password at the time of login can be omitted. Alternatively, stronger security can be ensured.

Hereinafter, a server that manages a two-dimensional code is described as a server, and a Web site that a user desires to log in is described as a Web site. Also, it is assumed that authentication information for logging in to the website and unique information of the mobile terminal possessed by the user are already registered in the server.
This registration can be realized, for example, by opening a Web page for user registration in the server, and the user accesses the page and enters the URL and authentication information of the Web site. Registration of the specific information of the mobile terminal can also be performed by accessing the registration site from the mobile terminal. Here, solid identification information (manufacturing number) is suitable as the unique information of the mobile terminal.
If the management entity of the server and the website is the same, or if the website only requires simple authentication, registration of authentication information is not essential. Also, there may be a plurality of websites registered by one user.

A specific procedure will be described below.
First, the user accesses the server from the PC terminal and selects one from a plurality of Web sites registered on the server. However, this operation is not essential if only one Web site is registered.
The server issues a two-dimensional code expressing unique information and returns it to the PC terminal. Then, the two-dimensional code is associated with the access information (session information) from the PC terminal and the information on the selected website and recorded in the database.
Here, it is necessary to maintain access to the server from the PC terminal, but this can be realized, for example, by automatically accessing a specific page of the server at regular intervals from the PC terminal. Automatic access at regular intervals can be realized by describing a meta tag in the HTML of the page accessed by the PC terminal.
In the PC terminal, a two-dimensional code is displayed on the display. The user captures an image of the two-dimensional code displayed on the PC terminal with the portable terminal, and transmits the information of the two-dimensional code and the unique information of the portable terminal to the server.
The server can acquire the session information and Web site URL between the PC terminal and the server from the received two-dimensional code information, and the authentication information from the received mobile terminal specific information.
Next, the server logs in to the Web site using the authentication information, and redirects the URL of the Web page returned as a result to the PC terminal. The redirect method can be realized by specifying a page accessed by the PC terminal at regular intervals from the specified session information and changing the meta tag of the page.

In this embodiment, an example in which the server is first accessed from the PC terminal has been described, but there is also a method of accessing the Web site from the PC terminal. In that case, it is preferable that the accessed website maintains a session with the PC terminal and issues a two-dimensional code issuance request to the server.
The server issues a two-dimensional code and associates the two-dimensional code with the requested website and records it in the database. The server transmits the issued two-dimensional code to the website and displays it on the display of the PC terminal via the website.
Thereafter, the server acquires information on the website from the information of the two-dimensional code, authentication information from the unique information of the mobile terminal, and transmits the authentication information to the website.
The website that has received the authentication information performs authentication, and returns the website page to the PC terminal that maintains the session. Alternatively, authentication may be performed within the server, and only the user information or only the result of whether authentication is possible may be transmitted to the website. Here, the authentication in the server may specify a registered user from the received unique information of the mobile terminal, or may further perform user authentication between the mobile terminal and the server.

  The server may have the following means.
  User authentication information registration means for registering user authentication information when a user logs into a predetermined WEB site in association with user identification information.
  User authentication information acquisition means for acquiring user authentication information based on the user identification information acquired by the user identification information acquisition means.
  User authentication requesting means for requesting user authentication for logging in to the WEB site using the user authentication information acquired by the user authentication information acquiring means.
  Login information transmission means for transmitting information for logging in to the WEB site to the client terminal that has made access.

  The user authentication information is information necessary for authentication when the user logs in to a predetermined WEB site, and may be an ID or password registered in advance. For example, it may be an encrypted bit string having a predetermined length.
  The user identification information and the user authentication information are preferably associated with each other and stored in a storage area accessible from the server. For example, user identification information and user authentication information of each user may be recorded in a user information table on the server.

  The server may have the following means.
  Login user registration means for registering a user permitted to log in to the WEB site.
  User authentication means for performing user authentication based on the user authentication information acquired by the user authentication information acquisition means.
  Authentication result transmission means for transmitting the authentication result by the user authentication means to the WEB site.

  The login user registration means may record whether each user can log in in the user information table on the server. Alternatively, a list of users permitted to log in may be held on the server.
  The user authentication means may perform user authentication based on the user identification information acquired by the user identification information acquisition means.
