Description:
TECHNICAL FIELD 
     The present invention relates to a creation method of creating a webpage for introducing content using a creation device connected therewith through a communication network to a web server in which the content is stored, and to an information introducing system and the creation device used for the method, and to a computer program and a recording medium for realizing a function of the creation device, and more particularly to a technology to appropriately protect copyright information on the content in the webpage to be introduced. 
     BACKGROUND ART 
     In recent years, what is called a blog (or weblog) has spread, in which a hyperlink to news articles or images that exist in a website on the Internet, or a hyperlink to a specific website is set up, and articles added with one&#39;s own criticisms to the news article to introduce it are arranged in a chronological order. Upon creation of a blog, the blog may be easily created on a browser by using software, such as BLOGGER or MOVABLETYPE (refer to Japanese Unexamined Patent Application Publication No. 2005-235118). 
     However, in many cases, contents published on the website, such as images, movies, or texts copyright has been granted. There is a problem that the contents are displayed in a user&#39;s blog without the user being conscious of the copyright in many cases. In the meantime, a procedure for the user to individually obtain an authorization of the copyright from a website administrator is complicated. 
     Further, images, movies, or the like on the website where news are published are set up with a publishing period by a contract. Thus, there also is a problem that the time period will lapse, even if the user introduced the image in his/her blog. 
     Further, depending on the content to be introduced, it may not be appropriate for regulations of each country from moral or legal perspective. Thus, it is necessary to impose certain access restrictions, also in the blog that can freely introduce contents.

The computer program recorded on the recording medium causes the computer to execute a step for receiving a selection of the content to be introduced from an input module, a step for causing the control module to extract an address and copyright information of the received content, and a sending step for causing the control module to send the address and the extracted copyright information of the content to a creation program for creating the webpage. 
     In the present invention, the information introducing system includes the web server in which content is stored, and the creation device connected with the web server through the communication network for creating a webpage for introducing the content. The web server transmits content, copyright information of the content, and execute information for executing an introduction of the content to the creation device. The creation device receives the content, the copyright information, and the execute information that are transmitted. When the control module determines that the introduction of the content is executed in association with the transmitted execute information, the creation device causes the control module to extract the transmitted copyright information of the content. In addition, the control module sends the address and the extracted copyright information of the content to the creation program for creating the webpage. 
     In addition, the creation device receives the comment related to the content from the input module. The creation device causes the control module to output the address and the copyright information of the content that are sent corresponding to the received comment to the open server computer connected therewith through the communication network. Thus, by performing the introduction of the content which a user wants to introduce, because the copyright information on the content is sent to the creation program and outputted to the open server computer, it is possible to appropriately protect a copyrighted work with easy processes, without bothering the website administrator who administrates the content, and the user. 
     In the present invention, the web server transmits the time-period information during which the publicizing of the content is permitted to the creation device. The control module of the creation device that received the time-period information displays the information indicating that the introduction period of the content ends, based on the transmitted time-period information. There fore, even when the user introduces a website where the publishing period of an image is set for the website, such as of news, the user can easily recognize an end-time of the publishing period. 
     In the present invention, the control module of the creation device stores the refusal address of the accessing end, introduction of which is to be refused, in the memory module. The creation device outputs the address of the content, the copyright information, and the refusal address corresponding to the content, corresponding to the received comment for the content, to the open server computer. In addition, the open server computer restricts viewing of the content by referring to the refusal address information and the address of the computer to which access is attempted. Therefore, the user is possible to impose the view restriction according to the morality or law of each country. Further, the website administrator who provides the content also is possible to reliably permit the introduction of the content by the user reliably. 
     In the present invention, the creation device receives the selection of the content to be introduced, from the input module. In addition, the control module extracts the address and the copyright information of the content that are received. The control module sends the address and the extracted copyright information of the content to the creation program for creating the webpage. The creation device receives the comment related to the content from the input module. The creation device outputs the address and the copyright information of the content that are sent corresponding to the received comment. Therefore, the user is possible to easily introduce the content expanding through the websites, while taking copyright into consideration. 
     In the present invention, the information introducing system includes the web server in which the content is stored, the creation device that creates the webpage to introduce the content, and the open server computer of the content, connected with each other through the communication network. First, the web server transmits the content, the execute information for executing the introduction of the content, and the address of the open server computer in response to a request from the control module of the creation device. The creation device accesses the open server computer with reference to the transmitted address of the open server computer, when the introduction of the content is executed in association with the transmitted execute information. Further, the address of the content is transmitted to the open server computer by the control module. The open control module of the open server computer receives the address of the transmitted content, and accesses the web server with reference to the address of the content. In addition, the open control module performs an acquisition request for the copyright information according to the address of the content to the web server. The web server transmits the copyright information corresponding to the content to the open server computer in response to the acquisition request. Thus, the open control module of the open server computer acquires the copyright information of the content. The open control module of the open server computer stores the acquired copyright information and the address of the content so as to correspond to each other. 
     Further, the creation device receives the comment related to the content from the input module. The creation device causes the control module to output the received comment to the open server computer. The open server computer stores the comment transmitted from the creation device so as to correspond it to the address and the copyright information of the content that has already been stored. Thus, because the copyright information is acquired when the execution of the introduction of the user&#39;s content, it is possible to adequately protect the content with a simple configuration. 
     In the present invention, the creation device extracts the transmitted copyright information of the content, when the introduction of the content is executed in association with the transmitted execute information. The creation device sends the address and the extracted copyright information of the content to the creation program for creating the webpage. Therefore, it is possible to appropriately protect a copyrighted work with easy processes, without bothering the website administrator who administrates content, and the user. 
     In the present invention, the creation device that received the time-period information displays the information indicating that the introduction period of the content ends, based on the transmitted time-period information. There fore, even when the user introduces the website where the publishing period of the image is set for the website, such as of news, the user can easily recognize the end-time of publishing period. 
     In the present invention, the creation device outputs the refusal address corresponding to the content to the open server computer. The open server computer restricts the viewing of the content by referring to this refusal address information and the address of the computer to which access is attempted. Therefore, the user is possible to impose view restriction according to the morality or law of each country. Further, the website administrator who provides the content also is possible to permit the introduction of the content by the user without anxiety by performing the view restriction. 
     Further, in the present invention, the control module extracts the address and the copyright information of the content that are received. The control module sends the address and the extracted copyright information of the content to the creation program for creating the webpage. The creation device receives the comment related to the content from the input module, and outputs the address and the copyright information of the content that are sent corresponding to the received comment. Therefore, it is possible for the user to introduce the content expanding through the websites with a simple configuration, while taking copyright into consideration. 
     Further, in the present invention, when the introduction of the content is executed, the open server computer according to the address transmitted with the execute information acquires the copyright information corresponding to the content from the web server. Therefore, information related to copyright can be displayed without the user who introduces the content being particularly conscious, and it is possible to appropriately protect the copyright of the content. As such, the present invention excels in the effects as above.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     (Embodiment 1) 
       FIG. 1  is a schematic view showing a configuration of an information introducing system according to the present invention. In the information introducing system S, a creation device  1 , a web server  2 , an open server computer  3 , and a third person&#39;s computer  4  are connected with each other through a communication network N, such as the Internet (hereinafter, referred to as “Internet N”). A known personal computer may be used as the creation device  1 , and hereinafter, the creation device  1  will be explained as a user computer  1 . Known server computers may be used as the web server  2  and the open server computer  3 , and the open server computer  3  will be explained as the blog server  3 . Further, as for the third person&#39;s computer  4 , a personal computer may be used. In the following embodiment, although the content to be introduced is an image, and a mode in which a user introduces the image by a so-called “blog” using the user computer  1  will be explained, the content may be a movie, a text, etc., as long as the content is a copyrighted work. 
     The web server  2  stores the content, and publishes a webpage on which the content is placed, through the Internet N. Here, in this embodiment, although the web server  2  publishes the webpage related to a newspaper article, it should not be limited to this. The user accesses the web server  2  using the user computer  1  to view the webpage. When content, such as an image, that is desired to be published to a third person exists in the webpage, the user creates a blog to which a comment related to this is added. The created blog is uploaded (transmitted) to the blog server  3 , and the third person&#39;s computer  4  can view this introduced content and the comment related to the content by accessing the blog server  3 . 
       FIG. 2  is a block diagram showing a hardware configuration of the user computer  1  and the blog server  3 . The user computer  1  is configured so as to include a CPU (Central Processing Unit)  11  that is a control module, and a RAM (Random Access Memory)  12 , a memory module  15 , an input module  13 , a display module  14 , and a communication module  16 . CPU  11  is connected with each hardware component of the user computer  1  through a bus  17  to control them, and executes various software-based functions according to a control program  151  stored in the memory module  15 , such as a hard disk drive. The control program  151  is described in a programming language, such as C language or JAVA®. 
     RAM  12  is constituted with a SRAM (Static Random Access Memory) or a flash memory to store temporary data generated at the time of execution of the software. For example, the input module  13  is constituted with a keyboard, a mouse, etc. to output information inputted by the user to CPU  11 . The display module  14  is constituted with a LCD (Liquid Crystal Digital) display, etc. Here, the input module  13  and the display module  14  may be integrated as a touch panel. 
     The memory module  15  stores a web browser  152  as a creation program for creating a webpage for introducing content (i.e., a blog). Further, the memory module  15  stores a time-period information file  153  for permitting publicizing of the content. The time-period information file  153  stores a period during which the publicizing is permitted so as to correspond it to an address, such as an URL (Uniform Resource Locate), of the content to be introduced. 
     The blog server  3  is configured so as to include a CPU  31  that is an open control module, a RAM  32 , a memory module  35 , an input module  33 , a display module  34 , and a communication module  36 . CPU  31  is connected with each hardware component of the blog server  3  through a bus  37  to control them, and performs various software-based functions. RAM  32  is constituted with a SRAM or a flash memory to store temporary data generated at the time of execution of the software. For example, the input module  33  is constituted with a keyboard, a mouse, etc. to output information inputted by the user to CPU  31 . The display module  34  may be constituted with an LCD display, etc. 
     The memory module  35  stores blog files  351  uploaded by each user. An authorized user can access the blog file  351  to suitably change the content. T he blog file  351  is open to the third person, and the third person can view the content by inputting the URL corresponding to the blog file  351  to the third person&#39;s computer  4 . 
       FIG. 3  is a block diagram showing a hardware configuration of the web server  2 . Similar to the blog server  3 , the web server  2  is configured so as to include a CPU  21 , a RAM  22 , a memory module  25 , an input module  23 , a display module  24 , and a communication module  26 . Because a function of each component is similar to that of the blog server, explanation thereof will be omitted. The memory module  25  stores a webpage file  251 , an ID management file  252 , and time-period information file  253 . 
     The webpage file  251  stores webpages, such as news articles and images, so as to be updated as needed. The ID management file  252  stores a user ID that can utilize the functions according to the present invention, and a password corresponding to the user ID. The time-period information file  254  stores time-period information corresponding to content on a webpage. That is, a publishing period may be set by some contract to the image to be published by news. CPU  21  refers to the time-period information on the content of the time-period information file  254 , and when it determines that the time-period information lapsed, it deletes the related contents from the webpage file  251 . 
       FIG. 4  is an explanatory diagram showing an image of the webpage displayed by accessing the web server  2 . The user computer  1  activates the web browser  152 , and then accesses the web server  2  using HTTP (Hyper Text Transfer Protocol). A user inputs a user ID and a password with the input module  13  prior to viewing the webpage. CPU  11  transmits the inputted ID and password to the web server  2  through the communication module  16 . CPU  21  of the web server  2  searches the ID management file  252  based on the ID and password that are received by the communication module  26 , and then determines whether they are identical to the ID and password stored in the ID management file  252 . When it determines that they are identical, a webpage for members in the webpage file  251  is read out, and it is then transmitted to the user computer  1  with the execute information described later. 
     As shown in  FIG. 4 , a webpage is displayed on the display module  14  of the user computer  1  by the web browser  152 . A date, an article, and an image (or content) are displayed on the webpage, and execute information for executing an introduction of the image is also displayed on the webpage. The execute information may be an “introduce” button  41  displayed on the browser in  FIG. 4 . The user is allowed to introduce the image by clicking the “introduce” button  41  with the input module  13 . T he execute information, such as “introduce” is described in HTML (Hyper Text Markup Language) that the execute information is displayed near the image data on the webpage file. 
     When the user executes the introduction of the image with the input module  13  of the user computer  1 , that is, when the user clicks the “introduce” button  41  that is the execute information, an address of the image and copyright information associated with the image is sent to the web browser  152  according to the control program  151  that is the creation program activated in advance. Here, in this embodiment, although it is configured so that the “introduce” button  41  that is the execute information is always displayed below the image on the web browser, it may be displayed only when a mouse pointer that is the input module  13  is located in the image area. In this case, another program may be added so that the execute information is displayed on the webpage by Flash etc., when the mouse pointer is coincident with the image area. 
     The image shown in  FIG. 4  is transmitted to the user computer  1  associated with an address indicating an accessing end of the image, the copyright information, and the time-period information. A tag corresponding to the copyright information and the time information associated with the image is defined in advance by some agreement. For example, handling of articles, images including the tag between websites that deal with news is defined by some agreement according to IPTC (International Press Telecommunications Council). CPU  11  of the user computer  1  extracts the copyright information and the time-period information referring to the tag related to the copyright information and the time-period information that are transmitted in accordance with the control program  151 . The extracted copyright information is stored in RAM  12  along with the address of the image, and the time-period information is stored in the time-period information file  153 . 
       FIG. 5  is an explanatory diagram showing an image of the web browser  152  that is a creation program. The user activates the web browser  152 , and then accesses the blog server  3 . After an authentication of the user, an edit screen for the blog shown in  FIG. 5  is displayed. The web browser  152  is provided with a title input box  51  for the blog, a date and time input box  52 , an address input box  53  for the image, a content box  54  into which the user&#39;s comment to the content is inputted, and the like. Information inputted in each input box is converted into HTML text, and is saved in the blog file  351  of the blog server  3 . In  FIG. 4 , when the user clicks the “introduce” button  41  that is the execute information with the input module  13  to start an execution of the introduction, CPU  11  describes the present time in the date and time input box  52 , extracts from RAM  12  the address of the image transmitted from the web server  2 , and sends it to the web browser  152 , according to the control program  151 . The address of the image sent to the web browser  152  is described in the address input box  53  for the image as shown in  FIG. 5 . 
     Similar to this, CPU  11  extracts the copyright information that is transmitted from the web server  2 , from RAM  12 , according to the control program  151 , and then sends it to the web browser  152 . The copyright information sent to the web browser  152  is described in the content box  54  as shown in  FIG. 5 . The user inputs a blog title (“today&#39;s article” in  FIG. 5 ) in the title box  51  by the input module  13  so that the blog for the image is completed. Further, following the described copyright information, a comment to the image is inputted into the content box  54  by the input module  13 . 
     When the user finished the input, the user clicks the “Post” button  55  with the input module  13 . By the operation of the “Post” button  55 , the inputted items are converted into HTML text, and the blog after the conversion is previewed on the webpage  152 . When the user determines that the content of the preview is satisfactory, the user then clicks a “Publish” button  56  with the input module  13  to upload the content of the blog to the blog server  3 . This blog is stored in the blog file  351  in the blog server  3 . 
       FIG. 6  is an explanatory diagram showing an image of the blog. When the third person accesses the blog server  3  to view the blog, CPU  31  reads out the HTML text from the blog file  351 , and transmits it to the third person&#39;s computer  4 . A screen image shown in  FIG. 6  is displayed on the browser of the third person&#39;s computer  4 . The browser of the computer requests the web server  2  for an acquisition of the image for the address with reference to the address of the image, and then displays an image as shown in  FIG. 6 . Further, the copyright information and the comment (“Mr. OO in this photograph is well known as a Japanophile.”) which are described in the content box  54  is displayed below the image. Thus, when the user executes the introduction of the content, and takes the content into the user&#39;s blog, the copyright information is sent to the web browser  152  by processing of the control program  151  without the user being conscious, and the copyright information is then added to the blog. 
     CPU  11  of the user computer  1  may periodically access the time-period information file  153 , and compares the time-period information during which the publicizing of stored information corresponding to the uploaded image is permitted with the present date and time to determine whether the publicizing is still possible. When the time period during which the publicizing is permitted lapsed, CPU  11  reads out from the memory module  15  the information indicating that the introduction period ended, and displays it on the display module  14  for warning. Again, the user can access the blog file  351  of the blog server  3  to delete the uploaded address or the comment of the image. 
       FIG. 7  or  9  are flowcharts showing a creation processing procedure of the blog according to the control program  151 . Based on an instruction of the user from the input module  13 , CPU  11  activates the web browser  152  (Step S 71 ). Under the condition of inputting URL related to the blog server  3  by the input module  13 , CPU  11  accesses the blog server  3  (Step S 72 ). When the user inputs an ID and a password with the input module  13  for login, CPU  11  receives this input, and transmits the received ID and password to the blog server  3  (Step S 73 ). 
     The blog server  3  determines whether the ID and password stored in the memory module  35  are identical to the incoming ID and password. CPU  31  terminates this routine when it does not succeed in this authentication (NO in Step S 74 ). On the other hand, when CPU  31  determines that it succeeded in the authentication (YES in Step S 74 ), CPU  31  then transmits the edit screen according to the blog file  351  corresponding to the ID to the user computer  1  (Step S 75 ). CPU  11  of the user computer  1  displays the edit screen transmitted to the web browser  152  as a creation program, as shown in  FIG. 5  (Step S 76 ). 
     Then, CPU  11  activates another web browser  152 , and accesses the web server  2  which distributes news, based on the URL inputted with the input module  13 . The user inputs the ID and password with the input module  13 . CPU  11  transmits the ID and password that are inputted with the input module  13  to the web server  2  (Step S 77 ). The web server  2  determines whether the ID and password stored in the ID management file  252  of the memory module  25  are identical to the incoming ID and password. When CPU  21  does not succeed in the authentication (NO in Step S 78 ), it then transmits a common screen image for non-members to the user computer (Step S 79 ), and then terminates this routine. On the other hand, when CPU  21  determines that it succeeded in the authentication (YES in Step S 78 ), CPU  21  then reads out the webpage stored in the webpage file  251 , and then transmits to the user computer as a screen image only for members (Step S 710 ). In the meantime, although the web server  2  requires the input of ID and password in this embodiment, this process may be omitted. 
     CPU  11  displays the transmitted screen image only for members on the web browser  152  which is activated by a window different from the web browser  152  activated in Step S 76 . The user views the webpage, and then selects an article to be described in the blog by the input module  13  (Step S 711 ). In response to the request from the input module  13 , CPU  21  of the web server  2  transmits information on the webpage related to the article. 
     CPU  21  transmits the article, the image, the address of the image, and the execute information for executing an introduction of the content to the user computer  1  (Step S 712 ). 
     Based on the information transmitted from the web server  2 , CPU  11  displays the webpage related to the article, as shown in  FIG. 4 . As shown in  FIG. 4 , the article, the image, and the “introduce” button  41  that is execute information for executing the introduction of the image are displayed on the web browser  152  (Step S 713 ). Further, CPU  21  reads out the copyright information and the time-period information associated with the image from the webpage file  251 , and then transmits them to the user computer (Step S 714 ). When the user computer  1  receives the copyright information, it then stores the information in RAM  12  so as to correspond it to the address information on the image, or when the time-period information is received, it stores the information in the time-period information file  153  so as to correspond it to the address information on the image (Step S 715 ). 
     When the execution of the content introduction is performed in association with the execute information from the input module  13  for executing the introduction of the content, that is, when the “introduce” button  41  associated with the image is selected by the input module  13  (Step S 716 ), CPU  11  then extracts the copyright information from RAM  12  (Step S 717 ). Then, CPU  11  sends the address of the image transmitted in Step S 712  and the copyright information transmitted in Step S 714  to the web browser  152  activated in Step S 76  that is a creation program (Step S 81 ). 
     CPU  11  displays the sent image address in the address input box  53  of the image of the web browser  152 , and further displays the sent copyright information in the content box  54 , as shown in  FIG. 5 . CPU  11  receives a comment of the user to the image inputted with the input module  13  (Step S 82 ), and displays it in the content box  54 . W hen CPU  11  receives an operation of the “Post” button  55  or the “Publish” button  56  with the input module  13 , it uploads (or transmits) the image address displayed in the address input box  53 , the copyright information displayed in the content box  54 , and the comment to the blog server  3  (Step S 83 ). 
     CPU  31  of the blog server  3  refers to the user&#39;s ID, and stores the uploaded image address, copyright information, and comment in the corresponding blog file  351  (Step S 84 ). When there is an access from the third person&#39;s computer  4  to the blog server  3 , and a viewing request for the user&#39;s blog is received, CPU  31  transmits the blog including the image address, copyright information, and comment that are uploaded to the blog file  351  to the third person&#39;s computer  4 . The third person&#39;s computer  4  displays the transmitted blog on the web browser, while it requests an acquisition of the image to the web server  2  with reference to the transmitted image address (Step S 85 ). 
     When CPU  21  of the web server  2  receives the acquisition request for the image, it reads out a corresponding image from the webpage file  251  with reference to the transmitted image address, and transmits the read-out image to the third person&#39;s computer  4  which is a requestor through the communication module  26  (Step S 86 ). The third person&#39;s computer  4  displays the blog transmitted from the blog server  3  and described in HTML, and the image transmitted from the web server  2  on a web browser. Near the transmitted image, the copyright information is displayed on the web browser along with the comment (Step S 87 ). 
     CPU  11  of the user computer compares the time-period information stored in the time-period information file  153  in Step S 715  and the present date and time at an appropriate timing, and then determines whether the image to be introduced falls within the introduction period (Step S 88 ). When CPU  11  determines that it falls within the introduction period (YES in Step S 88 ), CPU  11  repeats the above routine until the introduction period lapsed. On the other hand, when CPU  11  determines that it does not fall within the introduction period (NO in Step S 88 ), CPU  11  reads out an indication that the introduction period of the image is ended from the memory module  15 , and displays it on the display module  14  (Step S 89 ). Thus, even when the introduction period of the image lapsed, the user can easily know that the end-time, and is possible to delete the article related to the image from the blog. 
     In addition, similarly, if the content is an article, such as text, the execute information for introducing the content is displayed near the article, and the copyright information associated with the article is transmitted to the user computer  1 . Further, the address corresponding to the article is also transmitted to the user computer  1 , and a similar routine to the image is performed. 
     (Embodiment 2) 
     Embodiment 2 relates to a mode in which a view restriction of the blog is performed.  FIG. 10  is a flowchart showing a procedure of a view-restriction process according to Embodiment 2. First, CPU  11  of the user computer  1  receives an input of a refusal address for which viewing of an introduced blog is restricted, from the input module  13  (Step S 91 ). As for the refusal address, an IP address may be used, for example. Similar to Step S 83 , CPU  11  uploads a comment, an address of the image, copyright information, and the received refusal address to the blog server  3  (Step S 92 ). 
     CPU  31  of the blog server  3  refers to the user&#39;s ID, and then stores the uploaded comment, address of the image, copyright information, and received refusal address to the blog file  351  (Step S 93 ). When there is a viewing request for a blog from the third person&#39;s computer  4 , CPU  31  then compares the IP address of the computer according to the viewing request with the refusal address stored in the blog file  351 , and determines whether one is identical to the other (Step S 94 ). When CPU  31  determines that they are not identical (NO in Step S 94 ), it reads out an image address, copyright information, and comment from the blog file  351  (Step S 95 ). Then, the read-out image address, copyright information, and comment are transmitted to the IP address which made the viewing request (Step S 96 ). 
     The web browser of the third person&#39;s computer  4  refers to the transmitted address of the image, and then performs an acquisition request for the image to the web server  2  (Step S 97 ). Then, the web browser displays the transmitted image, as well as the copyright information and the comment (Step S 98 ). On the other hand, when CPU  31  determines that it is identical to the refusal address (YES in Step S 94 ), it reads out the view-restriction information stored in the memory module  35 , and reads out the copyright information and the comment from the blog file  351  (Step S 99 ). Then, CPU  31  transmits the view-restriction information, the copyright information, and the comment that are read out to the IP address according to the third person&#39;s computer  4  with view restriction (Step S 910 ). The web browser of the third person&#39;s computer  4  which received them does not display the image with the view restriction, and instead, it displays the view-restriction information, and further, it displays the copyright information and the comment (Step S 911 ). Thus, by a user who performs the introduction performing the view restriction, a newspaper publishing company which administrates the web server  2  may be possible to reliably permit the user to create a blog. 
     This Embodiment 2 is configured as above, and because other configuration and operations are similar to that of Embodiment 1, similar reference numerals are given to corresponding components and, thus, the detailed explanation thereof will be omitted. 
     (Embodiment 3) 
     The computer program for operating the user computer  1  may also be provided as a portable-type recording medium, such as a CD-ROM, MO to Embodiments 1 and 2 described above, like the this Embodiment 3. Further, it is also possible to provide the computer program by transmitting as a subcarrier via a communication line. Below, the description thereof will be explained. 
       FIG. 11  is a block diagram showing a hardware configuration of a user computer  1  and a blog server  3  according to Embodiment 3. A recording medium la (CD-ROM, MO, DVD-ROM, or the like) with which a program that causes a recording-medium reading device (not illustrated) of the user computer  1  shown in  FIG. 11  to receive the execute information, extract the copyright information, and send the address information and the copyright information is recorded is installed in the memory module  15 . Alternatively, this program may be downloaded from an external computer through the communication module  16 , and may be installed in the memory module  15 . This program is loaded to RAM  12  of the user computer  1  to be executed. Thus, this program may function as the user computer  1  of the invention as described above. 
     This Embodiment 3 is configured as above, and because other configuration and operations are similar to that of Embodiments 1 and 2, similar reference numerals are given to corresponding components and, thus, the detailed explanation thereof will be omitted. 
     (Embodiment 4) 
     The introduction process of content may be performed by the user computer  1  as described below.  FIG. 12  is an explanatory diagram showing an image of a webpage displayed by accessing the web server  2 . Same as Embodiment 1, an article transmitted from the web server  2  is displayed on the web browser  152 . When a user right-clicks desired content to be introduced by the input module  13  (in this example, the image is right-clicked), a separate window is displayed, and “introduce” as well as “properties” are displayed, as shown in  FIG. 11 . 
     When a user clicks this “introduce” by the input module  13 , CPU  11  extracts an address of the image, and copyright information associated with the image, and then sends the extracted image address and copyright information to the web browser  152  actuated as a separate window. The sent image address and copyright information are displayed as shown in  FIG. 5 . Thus, the processes described in Embodiment 1 may be added to the web browser  152  as a plug-in. 
       FIG. 13  is a flowchart showing a procedure of a creation process according to Embodiment 4. Because the processes of Step S 71  through Step S 76  are similar to that of Embodiment 1, explanation thereof will be omitted. In response to a request from the user computer  1 , CPU  21  of the web server  2  reads out an article, an image, and an address of the image, and copyright information from the webpage file  251 , and then transmits them to the user computer  1  (Step S 121 ). The web browser  152  of the user computer  1  displays the transmitted article, as shown in  FIG. 11  (Step S 122 ). CPU  11  determines whether it received a selection of the image from the input module  13  so that the user introduces the image (Step S 123 ). When CPU  11  determines that the selection of the image is not received (NO in Step S 123 ), it terminates the creation process. 
     On the other hand, when CPU  11  determines that it received the selection of the image (YES in Step S 123 ), for example, when a right-click is performed on the image area by the input module  13 , CPU  11  displays an introduction command (“introduce” in the figure) on the window of the web browser  152 , as shown in  FIG. 11  (Step S 124 ). In the meantime, in the case that the content is text, such as an article, a target area is specified by dragging on the article to be introduced by the input module  13 , and when the target area is right-clicked, the introduction command (“introduce” in the figure) may be displayed on the window of the web browser  152 , as shown in  FIG. 11 . The user selects the introduction command with the input module  13  when he/she desires to introduce the image. CPU  11  receives this introduction command (Step S 125 ), and then extracts the address and the copyright information on the image (Step S 126 ). 
     Then, CPU  11  sends the extracted image address and copyright information to the separate web browser  152  that is a creation program actuated in Step S 71  (Step S 127 ). Here, because the processes after this are similar to those explained in Embodiment 1, explanation thereof will be omitted. 
     The computer program for realizing the functions of the user computer  1  according to this embodiment may also be provided as a portable-type recording medium, such as CD-ROM, MO, etc. Further, it may be possible to provide the computer program by propagating as a subcarrier via a communication line. Below, the description thereof will be explained. 
       FIG. 14  is a block diagram showing a hardware configuration of the user computer  1  and the blog server  3  according to Embodiment 4. A recording medium  11   a  (CD-ROM, MO, DVD-ROM, or the like) with which a program causes the recording-medium reading device (not illustrated) of the user computer  1  shown in  FIG. 13  to receive the selection of the introduction content, extract the address information and the copyright information, and sends the address information and the copyright information is recorded is installed in the web browser  152  of the memory module  15  as a plug-in software. Alternatively, this program may be downloaded from an external computer through the communication module  16 , and may be installed as plug-in software of the web browser  152 . This program is loaded to RAM  12  of the user computer  1  to be executed. Thus, the program functions as the user computer  1  of the invention described above. 
     This Embodiment 4 is configured as above, and because other configuration and operations are similar to that of Embodiments 1-3, similar reference numerals are given to corresponding components and, thus, the detailed explanation thereof will be omitted. 
     (Embodiment 5) 
     In Embodiment 1, although it is configured that the user computer  1  acquires the copyright information and uploads it to the blog server  3 , the blog server  3  may acquire the copyright information. Herein below, the description will be explained using a flowchart.  FIG. 15  is a flowchart showing a procedure of a creation process according to Embodiment 5. Because the processes of Step S 71  through Step S 711  are similar to that of Embodiment 1, explanation thereof will be omitted. After Step S 711 , CPU  21  of the web server  2  transmits the selected article, image, execute information, and the address of the blog server  3  to the user computer  1  (Step S 151 ). 
     This execute information to be transmitted is described with hyperlink in which an address for accessing the blog server  3  is described in addition to those described in Embodiment 1. That is, in addition to HTML for displaying the “introduce” button  41 , HTML in which URL of the blog server  3  is described is inserted, and a screen image shown in  FIG. 4  is displayed on the web browser  152 . CPU  11  of the user computer  1  causes the web browser  152  to display the execution to which an article, an image, and a hyperlink to the blog server  3  are added on the display module  14  (Step S 152 ). When an introduction of the image is executed by an instruction of the user from the input module  13  (Step S 153 ), that is, when CPU  11  determines that there is an access request to the hyperlink for the blog server  3  in response to a click of the “introduce” button  41  with the input module  13 , CPU  11  accesses the blog server  3 , extracts the address of the image to be introduced from the web browser  152 , and then transmits it to the blog server  3  (Step S 154 ). 
     When the address of the image is transmitted in response to an access from the user computer  1  which has already logged in, CPU  11  of the blog server  3  stores the transmitted address to the blog file  351  in the memory module  35 . Then, CPU  31  accesses the web server  2  referring to the transmitted address of the image, and performs an acquisition request for the copyright information corresponding to the address of the image to be introduced (Step S 155 ). CPU  21  of the web server  2  reads out the copyright information corresponding to the address of the image to be introduced from the webpage file  251 , and then transmits it to the blog server  3  (Step S 156 ). Here, the acquisition of the copyright information may be performed as follows. CPU  31  accesses the web server  2  referring to the address of the image transmitted from the user computer  1 , and then receives the image and the copyright information associated with the image. Thus, an appropriate means for simultaneously receiving the image and the copyright information on the image stored in the webpage file  251  of the web server  2 , or receiving the copyright information only may be adapted. 
     CPU  31  of the blog server  3  stores the transmitted copyright information so as to correspond it to the address of the image stored in the blog file  351  (Step S 157 ). With the above processes, the address and the copyright information of the image which the user desires to introduce are uploaded to the user&#39;s blog so as to correspond to each other. Then, the user inputs a comment with the input module  13  to describe the comment to the image to be introduced. CPU  11  then receives the comment inputted from the input module  13  (Step S 158 ), and uploads the inputted comment to the blog server  3  when triggered by an operation of the “Post” button  55  or the “Publish” button  56  with the input module  13  (Step S 159 ). 
     CPU  31  of the blog server  3  stores the transmitted comment so as to correspond it to the copyright information and the image address stored in the blog file  351  of the user (Step S 1510 ). Because subsequent processes are similar to that described in Step S 85 , detailed explanation thereof will be omitted. Thus, the blog stored in the blog file  351  may be viewed by accessing from the third person&#39;s computer  4 . However, in this case, the address of the image and the copyright information are read out corresponding to the comment, and are displayed on the blog file  351 . Therefore, it is possible to protect the copyright of the content with easy operations at the blog server  3  end.
