Description

  The present invention relates to a network distribution type document browsing system, a document distribution server, a document distribution method, and a document distribution program for distributing contents that can be viewed on a mobile terminal device.

  In recent years, mobile phones have become more sophisticated, and have evolved from terminals with simple telephone functions to portable digital tools with various functions such as mail, camera, website browsing, music / video playback, and information management. is doing. Along with this, there is an increasing need to view electronic documents created on a personal computer (PC) on a mobile phone.

  However, mobile phones may be inferior in terms of processing capacity and storage capacity compared to PCs. In such a case, the functions that can be installed in the mobile phone are limited as compared with the PC. For example, an application used for a PC cannot be mounted on a mobile phone as it is. Some mobile phones may have applications that are compatible with PCs, but due to the limitations described above, the compatibility is low and it can be said that they are practical. Often not.

  A document file browsing system that converts a document file into a page-based image, extracts text information, and distributes the image and text information as a system that allows a personal computer document file to be viewed on a portable information terminal without format restrictions Has been proposed (see, for example, Patent Document 1).

  The method described in Patent Document 1 emphasizes that the contents (text) of a document file can be reliably grasped. That is, the function for browsing a document file with a mobile phone is not made to approach the function for browsing with a PC. For example, in the method described in Patent Document 1, hyperlink information included in a document file is ignored. Security aspects such as unauthorized access due to script tampering and information leakage after downloading are not particularly considered.

  If an external script or a script-integrated image format is used, content data can be flexibly controlled on the client side by passing values in query parameters. However, external scripts and query parameters are at risk of being tampered with. In addition, the script-integrated image format “Flash (registered trademark) Lite” for mobile terminals of Adobe Systems, which is compatible with many mobile phones, has a problem that it is not possible to pass values to contents by query parameters.

  By adding functions that should be performed to digital content itself, processing such as continuous search, editing, and extraction of related information based on the acquired content, content between different devices and processing procedures for that content There has been proposed a content functionalization device that enables the distribution of data representing the above, and allows various digital services to be used in combination (see, for example, Patent Document 2).

  In addition, by embedding the session information given for each session and the URL that received the request in the link tag and form tag included in the content file, tracking by selection of the link etc. is grasped for each session, and from the mobile phone There has been proposed an access log recording system that can cope with this type of access (see, for example, Patent Document 3).

Japanese Patent Laid-Open No. 2007-199983 JP 2006-313395 A JP 2007-86932 A

  According to the method described in Patent Document 2, the function for processing the content can be given to the content itself by pasting the procedure instruction data to the content and generating the functionalized content.

Embodiment 1. FIG.
A first embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram illustrating a configuration example of the network distribution type document browsing system according to the first embodiment. The network distribution type document browsing system shown in FIG. 2 includes a document distribution system 1 and a mobile terminal device (mobile phone) 3. Hereinafter, a mobile phone will be described as an example of the mobile terminal device. The document distribution system 1 and the mobile phone 3 are connected to be communicable via the network 2.

  The document distribution system 1 is a system that operates according to a program and distributes a document (content file) to the mobile phone 3 via the network 2. The document distribution system 1 generates a content file in which information received from the mobile phone 3 and means for controlling them (for example, a script) are embedded, and transmits the content file to the mobile phone 3. The mobile phone 3 operates according to the program, executes the received content file, performs data processing based on the embedded information and the control means, and displays it as content.

  The document distribution system 1 is realized by an information processing apparatus such as one or a plurality of personal computers that operate according to a program. The document distribution system 1 includes a server device (distribution server) 10, a content management database (DB) 11, an image (content) storage unit 12, a registration function unit 13, and an image conversion function unit 14.

  The image conversion function unit 14 converts an input file (document file, image file) to the document distribution system 1 into an image in page units using predetermined parameters, and outputs an image file. In FIG. 2, a document file and an image file are illustrated as input files. However, a file obtained by digitizing a document printed on paper using an OCR (Optical Character Reader) or the like may be used as an input file. Good. The image conversion function part 14 is implement | achieved by information processing apparatuses, such as a personal computer which operate | moves according to a program, for example.

  The registration function unit 13 registers the image file generated by image conversion by the image conversion function unit 14 in the image storage unit 12. Also, the registration function unit 13 registers information about the image file generated by image conversion by the image conversion function unit 14 in the content management DB 11. For example, the registration function unit 13 may automatically generate information about an image file and register the information in the content management DB 11, and information input by the administrator of the document distribution system 1 together with the input file may be stored in the content management DB 11. You may register with. The registration function unit 13 is realized by an information processing apparatus such as a personal computer that operates according to a program, for example.

  The image storage unit 12 is realized by a storage, for example, and stores content (image file).

  The content management DB 11 stores various types of information (content ID, storage location, title, etc.) about the content. For example, the content management DB 11 stores location information indicating the storage location of the content file and a title in association with the content ID.

  The distribution server 10 distributes the content file to the mobile phone 3 in response to a request from the mobile phone 3.

  The registration function unit 13 and the image conversion function unit 14 may be included in the distribution server 10.

  FIG. 3 is a block diagram illustrating a configuration example of the distribution server 10 and the mobile phone 3 according to the first embodiment. The distribution server 10 shown in FIG. 3 includes data transmission / reception means 101, content generation means 102, and location information acquisition means 103. The mobile phone 3 includes content display means 301.

  The data transmission / reception means 101 transmits / receives data to / from the mobile phone 3. For example, the data transmission / reception unit 101 passes a content browsing request transmitted from the mobile phone 3 to the content generation unit 102. In addition, the data transmitting / receiving unit 101 distributes the content file (for example, the Flash file) generated by the content generating unit 102 to the mobile phone 3 via the network 2 as a processing result for the browsing request.

  The browsing request is information including, for example, a content ID that can specify a content that requests browsing, and a page number of the content that requests browsing. When a session between the document distribution system 1 and the mobile phone 3 is established, the browsing request includes session information (ID) that can identify the established session. The browsing request may include time information extracted by the mobile phone 3, information indicating a display state, and the like, as will be described later.

  The location information acquisition unit 103 extracts the location information of the content requested to be browsed by the mobile phone 3 from the content management DB 11 in accordance with an instruction from the content generation unit 102, and outputs it to the content generation unit 102.

  The content generation unit 102 obtains necessary information based on the content browsing request received from the data transmission / reception unit 101, and dynamically generates a content file for each page.

  The content generation unit 102 inputs an image file (base image) from the image storage unit 12 based on the location information extracted by the location information acquisition unit 103. Further, the content generation unit 102 embeds information received from the mobile phone 3 and a unit for controlling them based on the image file, and generates a content file. For example, the content generation unit 102 dynamically generates a script-integrated content file (for example, a Flash file). That is, the script-integrated content is content generated based on the image file corresponding to each page of the original document (input file).

  In the first embodiment, the content generation unit 102 includes a session information embedding unit 104, a time information embedding unit 105, a period control unit embedding unit 106, and a display state embedding unit 107.

  The session information embedding unit 104 embeds session information capable of specifying a session between the document distribution system 1 and the mobile phone 3 in the image file input from the image storage unit 12. For example, the session information embedding unit 104 may pay out session information in response to a browsing request from the mobile phone 3 and embed it in the image file. Further, for example, session information included in a browsing request from the mobile phone 3 may be embedded in an image file.

  The time information embedding unit 105 embeds time information indicating the time when the mobile phone 3 makes a browsing request in the image file. The time information embedded by the time information embedding unit 105 may be time information stored in advance in the distribution server 10 or time information received from the mobile phone 3. For example, when the mobile phone 3 executes “means for acquiring time information for the next page” described later and transmits a browsing request including the time information to the document distribution system 1, the time information is embedded. The means 105 can embed the time information included in the browsing request in the image file.

  The time information embedding unit 105 also embeds a unit for acquiring time information for the next page in the image file. The “means for acquiring time information for the next page” means, for example, that the mobile phone 3 extracts time information stored in a storage unit (not shown) of the mobile phone 3 and includes the extracted time information. A means for generating a browsing request, which is realized by a script or the like.

  For example, a case where the mobile phone 3 first requests browsing of the first page of a certain content and receives the content file of the first page will be described. For example, when the display of the content file on the first page is executed, the mobile phone 3 executes a script included in the content file and extracts time information. When the mobile phone 3 requests to browse the second page, the mobile phone 3 transmits a browse request including the extracted time information to the document distribution system 1.

  The period control means embedding means 106 embeds information indicating a period during which content can be browsed in the image file. The information indicating the browsing period is, for example, information stored in advance by the period control unit embedding unit 106.

  The period control means embedding means 106 embeds means for controlling the display of content in the image file based on the time information and the information indicating the browsing period. The “means for controlling the browsing display of content” is a means for determining whether or not the content can be displayed, and is realized by a script or the like.

  For example, the mobile phone 3 executes a script included in the content file when displaying the received content file, and stores time information stored in the storage unit of the mobile phone 3 and information indicating a browsing period included in the content file; Based on this, it is determined whether or not the content can be displayed. For example, when the period from the time indicated by the time information to the current time exceeds the browsing period, the mobile phone 3 performs control so that the content is not displayed. Further, for example, the mobile phone 3 may be controlled not to display the content but also to delete the received content file itself.

  The display state embedding unit 107 embeds information indicating the display state in the image file. The information indicating the display state is information indicating display conditions when the mobile phone 3 displays content, for example, information indicating display conditions such as enlargement / reduction and rotation. For example, when the mobile phone 3 executes “means for acquiring a display state for the next page” described later and transmits a browsing request including information indicating the display state to the document distribution system 1, the display is performed. The state embedding unit 107 can embed information indicating the display state included in the browsing request in the image file.

  The display state embedding unit 107 embeds a unit for controlling the display state in the content file. The “means for controlling the display state” is, for example, a means for controlling the display setting of content, and is realized by a script or the like.

  For example, when the received content file is displayed, the mobile phone 3 executes a script included in the content file and displays the content based on information indicating a display state included in the content file. For example, when the information indicating the display state included in the content file means “rotate the content to the right by 90 degrees with respect to the display unit”, the mobile phone 3 sets the content to 90% with respect to the display unit. Rotate to the right and display.

  The display state embedding unit 107 also embeds a unit for acquiring the display state for the next page in the content file. The “means for acquiring the display state for the next page” includes, for example, information indicating the display state stored in the storage unit of the mobile phone 3 and information indicating the extracted display state. A means for generating a browsing request, which is realized by a script or the like.

  For example, when the display of the content file on the first page is executed, the mobile phone 3 executes a script included in the content file and extracts information indicating the display state. When the mobile phone 3 requests browsing of the second page, the mobile phone 3 transmits a browsing request including information indicating the extracted display state to the document distribution system 1.

  FIG. 3 illustrates the case where the content generation unit 102 includes all of the session information embedding unit 104, the time information embedding unit 105, the period control unit embedding unit 106, and the display state embedding unit 107. However, the content generation unit 102 does not have to include all the units, and may include any unit alone.

  The mobile phone 3 is a general-purpose mobile communication terminal, and includes content display means 301 corresponding to a script-integrated image format such as Flash Lite (see FIG. 3). The cellular phone 3 accesses the document distribution system 1 via the network 2 in response to a request from the user, and receives a content file. The content display unit 301 executes and displays the received content file.

  The mobile phone 3 may be a portable information terminal such as a PDA (Portable Personal Digital Assistant). However, the effect of the present invention is higher in a terminal having a low processing capability and a limited function, such as a mobile phone.

  Next, the operation of the first embodiment will be described with reference to the drawings.

  Content to be distributed needs to be registered in advance in the content management DB 11 and the image storage unit 12. An example of the operation will be described with reference to FIGS. FIG. 4 is a flowchart illustrating an example of processing for registering content.

  When there is a document conversion / registration request, the image conversion function unit 14 converts the input file (document file, image file, etc.) with the specified parameters, and outputs the image file to the specified location (step S1). When the conversion process ends normally, the image conversion function unit 14 makes a registration request to the registration function unit 13.

  The registration function unit 13 registers the image file output by the image conversion function unit 14 and information about the image file in the content management DB 11 and the image storage unit 12 with the designated parameters (step S2).

  Next, an example of the operation that characterizes the present invention will be described with reference to FIGS. FIG. 5 is a flowchart illustrating an example of processing for distributing content.

  The mobile phone 3 makes a content browsing request to the distribution server 10 via the network 2 (step S11).

  The data transmission / reception means 101 of the distribution server 10 receives a browsing request including information (content ID or the like) about the requested content (step S12). If a session between the document distribution system 1 and the mobile phone 3 has already been established (such as browsing a Web page), the data transmission / reception means 101 receives a browsing request including session information. The data transmission / reception unit 101 analyzes the received browsing request and outputs information about the requested content to the content generation unit 102.

  The content generation unit 102 extracts the location information of the requested content from the content management DB 11 via the location information acquisition unit 103. Further, the content generation unit 102 extracts an image file (base image) corresponding to the location information of the requested content from the image storage unit 12 (step S13).

  Next, the content generation unit 102 generates a script-integrated content file (for example, a Flash file) from the base image. At that time, the session information embedding unit 104 embeds the session information transmitted from the mobile phone 3 in the script portion of the content (step S14).

  Similarly, the time information embedding unit 105 embeds the time information in the script part as necessary. The time information embedded in the script part by the time information embedding unit 105 may be time information stored in advance in the distribution server 10 or time information received from the mobile phone 3. When receiving time information from the mobile phone 3, time transmitting means (means for extracting time information for the next page) is embedded in the script portion (step S15).

  Similarly, when controlling the browsing period, the period control unit embedding unit 106 embeds the browsing period in the script part. The period control means embedding means 106 checks the time information and the browsing period at the time of execution, and controls to prevent the content from being displayed when the permitted period has passed (controls the browsing display of the content). Is embedded in the script part (step S16). The means for controlling the browsing display of the content may not only display the content but also delete the content file itself.

  Similarly, the display state embedding unit 107 embeds information indicating the display state in the image file when receiving a browsing request including information indicating the display state from the mobile phone 3. The display state embedding unit 107 embeds a means for processing the display state with the mobile phone 3 (means for controlling the display state) in the script portion. When the information indicating the display state is received from the mobile phone 3, a means for acquiring the display state for the next page is embedded in the script part (step S17).

  The content generation unit 102 transmits the content file generated as described above to the data transmission / reception unit 101. The data transmitting / receiving unit 101 distributes the content file to the mobile phone 3 via the network 2 as a result of the browsing request (step S18).

  When receiving the content file, the mobile phone 3 executes the content file using the content display unit 301 and displays the result on the screen according to the control by the script embedded therein (step S19).

  As described above, according to the first embodiment, it is possible to make data tampering difficult and enhance security (data robustness). This is because a script-integrated image format such as “Flash” of Adobe Systems Incorporated was adopted and the script part was binarized.

  In addition, data control on the mobile phone side is possible even in a format such as Flash Lite that does not support parameter passing. Thereby, delivery of session information etc. is also attained. This is because information necessary for control on the mobile phone side is dynamically embedded in a script-integrated image format.

  Content reflecting operation / state information in the mobile terminal device can be generated. This is because a means for dynamically generating content in response to access is provided, and information acquisition means and data control means from the mobile terminal device are embedded in the content.

  Even if the mobile phone does not hold information, the page can be moved while maintaining the display state. This is because the control means for the display state (enlarged / reduced state, rotated state, etc.) and the information acquisition means for browsing the next page are dynamically embedded in the content.

  In addition, an access control function can be provided. This is because the browsing period control means for checking the time information and the time information at the time of display is embedded in the content. As a result, even when the content (Flash file) is stored in the mobile phone, the image cannot be displayed when the access permitted period has passed. Further, by embedding the time information acquired from the mobile phone instead of the time information stored in the server in the content, an effect can be obtained even when the time information of the mobile phone is invalid. Further, the access control function can be further strengthened by embedding control means for discarding the own file (content file itself) when the period has passed.

  Further, the above-described functions can be realized without giving a special function to the mobile phone. This is because the means for controlling the data and the means for extracting the data for the next page are embedded in the content data.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to the drawings. Note that components similar to those in the first embodiment are denoted by the same reference numerals as those in FIGS. 2 and 3 and description thereof is omitted.

  FIG. 6 is a block diagram illustrating a configuration example of the network distribution type document browsing system according to the second embodiment. As shown in FIG. 6, the document distribution system 1 in the second embodiment includes a text / coordinate extraction function 15 that is not provided in the first embodiment.

  The text / coordinate extraction function 15 extracts text information and coordinate information indicating the coordinates of the text information from the input file.

  The image conversion function unit 14 uses the text / coordinate extraction function 15 together when converting the input file into an image. The registration function unit 13 registers information about the image file and text information and coordinate information extracted by the text / coordinate extraction function 15 in the content management DB 11.

  FIG. 7 is a block diagram illustrating a configuration example of the distribution server 10 and the mobile phone 3 according to the second embodiment. The distribution server 10 illustrated in FIG. 7 includes a hyperlink information acquisition unit 108 that is not provided in the first embodiment. In addition, the content generation unit 102 includes a hyperlink embedding unit 109.

  In the example shown in FIG. 7, the content generation unit 102 includes only the hyperlink embedding unit 109. However, in addition to the unit included in the content generation unit 102 in the first embodiment, the content generation unit 102 includes the hyperlink embedding unit 109. It may be replaced with any means.

  The hyperlink information acquisition unit 108 searches text information stored in the content management DB 11 and extracts hyperlink information indicating URL information of other documents included in the content requested to be browsed by the mobile phone 3. The hyperlink information is information including URL information included in a request page (content requested to be viewed by the mobile phone 3) and coordinate information corresponding to the URL information.

  The hyperlink embedding unit 109 embeds the hyperlink information extracted by the hyperlink information acquisition unit 108 and an interface necessary for access in a script-integrated content file (for example, a Flash file). The “interface necessary for access” is means for requesting and receiving the content indicated by the hyperlink information, and is realized by a script or the like.

  FIG. 8 is a block diagram illustrating another configuration example of the distribution server 10 and the mobile phone 3 according to the second embodiment. In the distribution server 10 illustrated in FIG. 8, the content generation unit 102 includes a time information embedding unit 105 and an identification information embedding unit 110 that is not provided in the first embodiment. The mobile phone 3 illustrated in FIG. 8 includes an individual identification information transmission unit 302 that is not provided in the first embodiment.

  In the example shown in FIG. 8, the content generation unit 102 includes only the identification information embedding unit 110 and the time information embedding unit 105, but in addition to the unit included in the content generation unit 102 in the first embodiment, The information embedding means 110 may be provided, or any means may be replaced.

  The individual identification information transmitting unit 302 transmits individual identification information that can identify the mobile phone 3 when accessing the document distribution system 1. For example, the individual identification information transmission unit 302 transmits a browsing request including the individual identification information to the document distribution system 1. The individual identification information transmitting means 302 is provided as a standard in recent mobile phones.

  The identification information embedding unit 110 embeds user information such as individual identification information included in the browsing request received from the mobile phone 3 in a script-integrated content file (for example, a Flash file).

  FIG. 9 is a block diagram illustrating still another configuration example of the distribution server 10 and the mobile phone 3 according to the second embodiment. In the distribution server 10 illustrated in FIG. 9, the content generation unit 102 includes an image synthesis unit 111 that is not provided in the first embodiment. The mobile phone 3 illustrated in FIG. 9 includes individual identification information transmitting means 302 that is not provided in the first embodiment, similarly to the mobile phone 3 illustrated in FIG.

  In the example shown in FIG. 9, the content generation unit 102 includes only the image synthesis unit 111. However, the content generation unit 102 may include the image synthesis unit 111 in addition to the units included in the content generation unit 102 in the first embodiment. Also, any means may be replaced.

  The image synthesizing unit 111 synthesizes user information such as individual identification information and time information for determining the access time, not the script portion of the content file but the base image file itself.

  According to 2nd Embodiment, in addition to the effect by 1st Embodiment, there exist the following effects.

  According to the second embodiment, a hyperlink function can be provided. This is because the URL information is extracted from the text information extracted from the base document (base image), the URL information and link coordinate information are embedded in the content file, and an access means for the link destination is prepared. The mobile phone is not suitable for inputting a long character string such as a URL. However, for example, it is possible to jump to a link simply by pressing a key, and operability / convenience can be improved. Further, even when the original document does not have a hyperlink setting of the URL, it is possible to provide a function.

  Further, it is possible to improve the tracking ability when information is leaked. This is because user information such as individual identification information is embedded in the content file. This effect can be further improved by embedding accessed time information.

  In addition, the effect of improving the tracking ability at the time of information leakage can be enhanced and the information leakage can be psychologically suppressed. This is because the user information is synthesized not with the script portion of the content file but with the image data itself. This effect can be further improved by embedding accessed time information.

  Furthermore, an image corresponding to the unique information (resolution, communication speed) of the individual (particularly model) can be provided by resizing or the like. For example, by acquiring the model of the mobile phone as the solid identification information, the image can be resized and distributed according to the model.

  In the embodiment described above, a network distribution type document browsing system having a characteristic configuration as shown in the following (1) to (6) is shown.

  (1) A network-distributed document browsing system that distributes content to a mobile terminal device (for example, realized by a mobile terminal device (mobile phone) 3) via a network. A server device (for example, realized by the server device (distribution server) 10) is provided, and the server device responds to a request from the mobile terminal device, and specifies content display status and content based on the information. Content generation means (for example, realized by the display state embedding means 107) that generates script-integrated content in which a script for performing control related to the embedded information is embedded, and the mobile terminal device is embedded in the script-integrated content.
