Description

  The present invention relates to a content access control system in which only registered users can access content displayed on a browser or the like. In particular, whether or not the content of the content is visible to the registered user is determined based on attribute information composed of personal attributes (gender, age, etc.) and status data (biological information, emotion information, etc.) of the registered user. The present invention relates to a content access control system.

  In recent years, a social networking service (SNS) has been operated for the purpose of expanding new friendships by introducing participating friends to each other. In addition, functions such as a diary that can be browsed only by friends among the participating users are also provided, and the user should be a diary that can be browsed only by friends, or all users who are participating Can be selected as a diary that can be viewed.

  Specifically, a content access control system has been proposed in which content such as a diary displayed on a Web browser is a page format document that is published on the Internet using the WWW (World Wide Web) system. (See Patent Document 1).

JP 2002-91915 A

  However, in the above-described system, the content is displayed on the user terminal depending on whether or not the user accessing the content is restricted from accessing the content page. Therefore, the contents of the service provided by the system are limited to the contents that only a fixed specific user can access the contents due to the access restriction. As a result, even if it is possible to publish the content created by itself to a specific user, it is possible to meet the demand to publish it to an unspecified number of users who need the content of their own due to access restrictions. There wasn't.

  Also, the person who publishes the content can change the content created by himself (for example, a diary) or only a part (for example, an article in the diary) according to the situation of the user. It was not possible to respond to the request to publish to the users who needed it. In particular, it is not practical to set access restrictions according to the user's situation that changes from moment to moment for each portion included in the content because it requires a very complicated operation and labor.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to dynamically set and change access restrictions on the user's content according to the user's situation that changes from moment to moment. It is to provide a content access control system capable of performing the above. In addition, content that can set access restrictions without setting the access restriction for each part of the content, instead of setting access restrictions for the entire content according to the user's situation that changes from moment to moment It is to provide an access control system.

In order to achieve the above object, in the content access control system according to the present invention,
Attribute information extraction means for extracting attribute information indicating the content content as extracted attribute information;
Access right control means for dynamically changing a setting of an access right of a registered user who can access the content based on a result of comparing the attribute information of the registered user and the extracted attribute information;
It is characterized by that.

  According to the above-described invention, the attribute information extraction unit can extract the attribute information indicating the content of the content that satisfies the attribute condition for extracting the attribute information as the extracted attribute information for all the contents. The access right control means can dynamically change the setting of the access right of the registered user who can access the content based on the result of comparing the registered user attribute information with the extracted attribute information.

  Accordingly, since the access right is dynamically changed, a registered user who accesses his / her content can make the desired registered user access his / her content. As a result, it is possible to save the trouble of changing the setting of the access right for each content for the registered user who accesses the content.

  Furthermore, a registered user accessing the content can access the content desired by the user. In particular, since the setting of the access right is dynamically changed based on the registered user attribute information, it is possible to access the desired content reflecting the changing registered user attribute information.

  Here, the “browser means” is means for displaying / browsing content, for example, a Web browser. The “content” displayed on the browser means, for example, character string information such as a diary and image information.

  The “access right” is a right associated with the registered user, and is determined based on the attribute information to determine whether the content (for example, character string information such as a diary) is visible. The right that the registered user can access the contents of

  In the specification of the present application, “dynamic change of access right setting” automatically changes the setting of access right based on the result of comparing the attribute information of the registered user with the extracted attribute information. That means.

As a content access control system according to the present invention,
Attribute information storage means for storing the attribute information of the registered user;
A terminal that transmits status data constituting the attribute information of the registered user to the attribute information storage means;
The terminal
Acquire situation data including at least one piece of information from the user's own biological information, emotion information estimated from the biological information, his / her surrounding information, and environmental information estimated from the surrounding information Status data acquisition means for
Terminal identification means for transmitting user identification information for identifying a user and the situation data acquired by the situation data acquisition means to the attribute information storage means;
It is preferable.

  According to the above-described invention, it is possible to change the setting of the access right based on the registered user attribute information reflecting the status data such as the biometric information of the terminal user. Accordingly, it is possible to change the setting of the access right linked to the status data of the terminal user.

  Here, the “terminal” means a means for transmitting status data constituting “registered user attribute information” stored in the attribute information storage means to the attribute information storage means. Note that a terminal that transmits status data and a browser unit, for example, a PC terminal, are not limited to separate ones, and are preferably integrated.

  “Status data” refers to the biometric information, emotion information, location information, etc. of the terminal user. “Attribute information” composed of status data refers to status data and personal attribute data such as age and gender. It consists of

  The content access control system according to the present invention preferably further includes character string analysis means for analyzing the character string information of the content.

  According to the above-described invention, the extraction processing of the extracted attribute information by the attribute information extracting unit can be speeded up by the character string analyzing unit analyzing the analysis information.

  Here, “content character string information” means “character string information (for example, HTML tag) constituting the content” or “character string information associated with the content (eg, associated with image / video content). Character string information including "character string (tag))".

  In the content access control system according to the present invention, it is preferable that the access right control means changes the setting of the access right when the registered user tries to access the content.

  According to the above-described invention, regardless of whether or not the access right setting is changed, the content of the content is recognized with respect to the content recognized by the registered user without always performing the process for changing the access right setting. The access right setting can be changed only by detecting the timing of accessing the. Therefore, the processing load can be reduced, the memory capacity can be reduced, and the processing speed can be increased.

  The access right control means preferably changes the access right setting when the attribute information is changed, or changes the access right setting when the contents are updated.

  Furthermore, it is preferable that the content access control system according to the present invention further includes content update means for updating the content displayed on the browser means based on the access right setting changed by the access right control means.

  “Updating” means updating the display contents so that the contents for which the access right is not set are not displayed on the browser means of the access control system. Therefore, according to the above-described invention, when the component in the system other than the terminal, for example, the content server includes the content update unit, the content for which the access right is not set by the CGI (Common Gateway Interface) is displayed as the browser unit. Since the information (HTML file) that is not displayed on the screen or the information (HTML file) that does not display the content of the content for which the access right is not set can be generated on the browser means, the browser means is based on the generated information. Content can be displayed.

  On the other hand, even when a terminal equipped with browser means is equipped with content update means, information that does not allow the browser means to display content for which access rights are not set, or access rights, due to a mechanism that provides a dynamic function on the terminal side. Since it is possible to generate information that does not cause the browser means to display the content of the content that is not set, the browser means can display content based on the generated information.

  According to the above-described invention, since it is possible to dynamically change the setting of the access right of a registered user who can access the content, the registered user who accesses his / her content gives his / her content to the desired registered user. Can be accessed. As a result, it is possible to save the trouble of changing the setting of the access right for each content for the registered user who accesses the content.

  Furthermore, a registered user accessing the content can access the content desired by the user. In particular, since the setting of the access right is dynamically changed based on the registered user attribute information, it is possible to access the desired content reflecting the changing registered user attribute information.

  The content access control system according to the present invention is capable of dynamically setting and changing access restrictions on the user's content without requiring a user's complicated operation according to the user's situation that changes from moment to moment. is there.

  According to the content access control system according to the embodiment of the present invention, for example, as shown in FIG. 1, A that is an SNS registrant, B that has a friendship relationship with A, and C that does not have a friendship relationship with A. 4 and D, and E, who is not an SNS registrant, access to diary articles (Articles on July 1, July 2, and July 3) that are contents published by A Since B has a friendship relationship with A, he can access a diary article which is a content published by A. On the other hand, since C has no friendship with A, he cannot access the content in principle, but C is raising a child and stays at Osaka Station. Is interested in, so that it is possible to access articles of “July 2” and “July 3”, which have parenting as the content. D, like C, has no friendship with A, so in principle it cannot access the content, but C is staying at Disney (R) Land, so he is interested in Disney Land. As a result, it is possible to access “July 2” articles whose content is Disneyland, but when D moves to Osaka, no article can be accessed. Is. Since E is an SNS non-registered person, the content cannot be accessed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the first embodiment, every time a registered user accesses content, it is determined whether or not there is permission to access the content. On the other hand, in the second embodiment, when the registered user accesses the content, the access permission is determined by referring to the “access list” that sets whether or not each registered user has permission to access each content. To do.

<<<< First Embodiment >>>>

The content server 40 includes a transmission / reception unit 51 that enables transmission and reception of signals from the communication portable terminal 10 and the PC terminal 60, an update determination unit 52 that determines whether the content has been updated, When it is determined that the content has been updated, the update storage unit 53 that stores the update content in the content database 58, the update data analysis unit 54 that analyzes the character string information of the updated content, From the extracted information storage unit 55 that extracts the attribute information indicating the content of the content that satisfies the attribute conditions for extracting the attribute information as the extracted attribute information (access permission list), and the status data and personal attribute data of the registered user A user information storage unit 56 for storing the attribute information as a situation management table, It has an access control unit 57 to change the setting of access rights, and a content database 58 for storing content data such as HTML documents and images.

  In other words, when the content determination unit 52 determines that the content has been updated, the content server 40 stores the content updated by the update storage unit 53 in the content database 58 and sets the attribute condition for the updated content. The attribute information indicating the content content satisfying the condition is analyzed, the extracted attribute information is extracted, and added to the access permission list. Further, the attribute information of the registered user who uses the communication portable terminal 10 is stored in the user information storage unit 56. As a result, the content server 40 can change the access right for each registered user by the access control means 57 based on the registered user attribute information stored in the user information storage unit 56 and the access permission list. It becomes possible to display the content for which the access right is set by using the browser function of the PC terminal 60 of the registered user.

<<< Control processing of content server 40 >>>
<< Main processing >>
The main process of the content server 40 will be described with reference to FIG. In the content server 40 of the content access control system according to the first embodiment, every time a registered user accesses the content, whether or not there is an access permission for the content is determined based on the presence or absence of the access right.

  First, the content server 40 determines whether there is a request for access to the content of the registered user from the PC terminal 60 to the content server 40 (step S10). If it is determined in step S10 that there is no access request (NO), the access request determination process in step S10 is repeated. On the other hand, when it is determined that there is an access request (YES), the attribute information of the registered user stored in the user information storage unit 56 is acquired from the situation management table (FIG. 6) described later (step S11). Here, “registered user attribute information” refers to status data such as biometric information, emotion information, environmental information, and location information of a registered user who is a user of the communication portable terminal 10, as well as age, gender, origin, Personal attribute data such as hobbies and family composition.

  In step S11, after the attribute information of the registered user is acquired from the situation management table (FIG. 6), an analysis process for analyzing the character string information of the content is executed (step S12). The analysis process will be described later with reference to FIG.

  After executing the analysis process (step S12), the access right list (FIG. 7) stored in the extraction information storage unit 55 is referred to, and the registered user who has requested access sets the access right for each content. It is judged whether it is (step S13). Specifically, the attribute information of the registered user registered in the status management table (FIG. 6), that is, the registered user who executed the access request, and the extracted attribute information set for each content in the access permission list (FIG. 7) And determine whether or not the user has the access right.

  In step S13, after the access right setting determination process is completed, a content display process for displaying the content for which the access right is set by using the browser function of the PC terminal 60 of the registered user is executed (step S13). S14).

  Here, the content display process executed by the content server 40 determines whether or not the registered user who has requested access to the content has an access right to access the content, and then the PC terminal of the registered user. Information relating to content display using the browser function 60 is transmitted to the PC terminal 60. Here, the “access right” is a right associated with the registered user, and the registered user has access to the content content determined based on the attribute information to determine whether or not the content content is visible. A right that can be done.

  Specifically, the content server 40 displays the content for which the access right is set by using the browser function of the PC terminal 60, while the content server 40 for the content for which the access right is not set, for example, Information not to display the contents on the PC terminal 60 is transmitted to the PC terminal 60.

  Therefore, the PC terminal 60 that has received information related to content display can realize content display based on the received information. The content display process executed on the registered user's PC terminal 60 will be described later with reference to FIGS.

  And it is judged whether the power supply of the content server 40 is set to OFF (step S15). When it is determined that the power is set to OFF (YES), all the processes are finished and the main process of the content server 40 is finished. On the other hand, when it is determined that the power is not set to OFF (NO), the process returns to step S10 and the processes of steps S10 to S15 are repeated.

<< Analysis process >>
The analysis process (step S12) executed by the update data analysis unit 54 of the content server 40 will be described with reference to FIG. In the analysis process, the character string information of the content is analyzed. Here, the “character string information of the content” is not limited to “character string information (for example, HTML tags) constituting the content content”, but “character string information associated with the content (for example, Character string information including “character string (tag) associated with image / video content”.

  In the analysis process, first, content to be analyzed is acquired from the content database (step S20). Then, it is determined whether or not there is time information in the character string information of the content (step S21). If it is determined in step S21 that there is time information (YES), a time information acquisition process (step S22) for acquiring time information is executed, and the process proceeds to step S23. On the other hand, if it is determined in step S21 that there is no time information (NO), the process proceeds to step S23 without acquiring time information.

  Then, it is determined whether or not the character string information of the content includes position / location information (step S23). If it is determined in step S23 that there is position / location information (YES), position / location information acquisition processing (step S24) for acquiring position / location information is executed, and the process proceeds to step S25. On the other hand, when it is determined in step S23 that there is no position / location information (NO), the process proceeds to step S25 without acquiring the position / location information.

  Then, it is determined whether or not there is character information in the character string information of the content (step S25). If it is determined in step S25 that there is character information (YES), character information acquisition processing (step S26) for acquiring character information is executed, and the process proceeds to step S27. On the other hand, when it is determined in step S25 that there is no character information (NO), the process proceeds to step S27 without acquiring the character information.

  In step S27, the information extracted by the time information acquisition process (step S22), the position / location information acquisition process (step S24), and the character information acquisition process (step S26) is permitted to access the extracted information storage unit 55. It stores in the list (see FIG. 7) (step S27).

  An example in which the analysis process (FIG. 4) is performed on the acquired content will be described with reference to FIG. The content shown in FIG. 5 includes position / location information “XX amusement park” and time information “6 o'clock” and “9 o'clock” in an article in the diary that is the content of the content. Here, by referring to an analysis dictionary in which character string information is registered in advance for extracting information, and comparing and comparing with the character string information of the contents, “○ × amusement park” which is position / location information and time Information “6 o'clock” and “9 o'clock” are extracted (steps S21 to S26). Then, the extracted information is stored in the extracted information storage unit 55 in the form of an access permission list (FIG. 7) (step S27).

  In the present embodiment, position information including latitude and longitude and location information are registered in the location / location information of the analysis dictionary. When “○ × Amusement park” is extracted as the location information, the latitude and longitude are also extracted, and conversely, for example, a position / latitude consisting of latitude and longitude within a radius of 1 km centering on the extracted latitude and longitude points. The location information is also set so that it can be extracted as the same location information “○ × amusement park”.

<Status management table>
The situation management table is a table configured from registered user attribute information stored in the user information storage unit 56. The situation management table will be described with reference to FIG. In the situation management table shown in FIG. 6, for user B, the location / location information is registered as “Osaka Station”, the emotion information is “excited”, and the presence / absence of children is registered as attribute information. For C, the location / location information is “Disneyland”, the emotion information is “Shock”, the presence / absence of children is “Yes” as attribute information, and for D, the location / location information is “Disneyland”, The emotion information is “cool”, and “nothing” is registered as attribute information regarding the presence or absence of children.

<Access permission list>
The access permission list is a table list composed of attribute information (extraction attribute information) indicating the contents stored in the extraction information storage unit 55. The access permission list will be described with reference to FIG. The access permission list shown in FIG. 7 is a table list in which position / location information, date / time information, emotion information, and character information are set for each of the four contents 1 to 4. Specifically, for the content 1, the location / location information is set to “not specified”, the date / time information is set to “not specified”, the emotion information is set to “all emotions”, and the character information is set to “no condition”. Position / location information is “not specified”, date / time information is “not specified”, emotion information is “cool”, character information is “children”, and location / location information is “Disneyland” for content 3 , The date / time information is set to “not specified”, the emotion information is set to “all emotions”, the character information is set to “children”, the content / location information is “Tokyo Station”, and the date / time information is “not specified”. The emotion information is set to “all emotions” and the character information is set to “no condition”.

<< Content display processing >>
The content display process executed in the registered user's PC terminal 60 will be described with reference to FIGS. FIG. 8 is a flowchart for executing content display processing executed in the PC terminal of the content access control system according to the first embodiment. FIG. 9 is a content display example in which the content display process of FIG. 8 is executed.

  In the content display processing, content display information transmitted from the content server 40 to the PC terminal 60, that is, content for which access rights are set is displayed by using the browser function of the PC terminal 60. On the other hand, for the content for which the access right is not set, for example, the content is displayed using the browser function of the PC terminal 60 based on the information that does not cause the content of the content to be displayed on the PC terminal 60.

  In the content display process, first, the registered user who has executed the access request has an access right to the content based on the information transmitted to the PC terminal 60 by the content display process (step S14) of the content server 40. Whether or not (step S30).

  In step S30, when it is determined that the registered user who executed the access request has the access right to the content (YES), the content of the content with the access right is displayed by using the browser function of the PC terminal 60. (Step S31), and the content display process is terminated.

  On the other hand, when it is determined that the registered user who executed the access request does not have access right to the content (NO), an error display is performed (step S32), and the content display processing is terminated.

  Accordingly, in the content display process (step S14) of the content server 40, information (HTML file) that prevents the display of content for which access rights are not set using the browser function of the PC terminal 60 by CGI (Common Gateway Interface). ), Or information (HTML file) that does not display the contents of the content that is displayed but whose access right is not set can be generated, and the PC terminal 60 is based on the generated information. Content can be displayed.

  The content display process when the registered user C executes an access request will be described with reference to FIG. As shown in the situation management table (FIG. 6), for the registered user C, the location / location information is registered as “Disneyland”, the emotion information is “impact”, and the presence / absence of children is registered as attribute information. . Therefore, based on the extracted attribute information set in the access permission list (FIG. 7) and the attribute information of the registered user C, the registered user C has access rights to the contents 1 and 3, and the contents 2 and 4 Has no access rights.

  FIG. 9 is an example of content display in which content display processing (steps S31 to S32) for the registered user C is executed using a Web page as an example. First, the content 1 (registered by Mr. A) of the registered user A who publishes the content is allowed access to all registered users. Therefore, content 1 is displayed, content 2 (7/1 (Monday) diary), content 3 (7/2 (Tue) diary), and content 4 (7/3 (Wednesday) diary). Is displayed on the content 1.

  Here, since the registered user C has access rights to the contents 1 and 3 and does not have access rights to the contents 2 and 4, when the heading of the contents 3 is clicked, the registered user C accesses the contents 3 contents. When the heading of the content 2 or 4 is clicked, an error message indicating “no authority to display this page” is displayed.

<Modification 1 of content display processing>
Modification 1 of the content display process will be described with reference to FIGS. 10 and 11. FIG. 10 is a flowchart for executing the first modification of the content display process. FIG. 11 is a content display example in which the first modification of the content display process of FIG. 10 is executed.

  In the first modification, unlike the content display example in FIG. 9, content having access rights is displayed simultaneously. That is, as a result of determining whether or not there is access right for each content, content that does not have access right to the content is not displayed.

  In the first modification of the content display process, first, a registered user who has executed an access request performs a process on content based on information transmitted to the PC terminal 60 by the content display process (step S14) of the content server 40. It is determined whether or not the user has an access right (step S40). If it is determined in step S40 that the registered user who executed the access request has the right to access the content (YES), the content having the access right is displayed using the browser function of the PC terminal 60 of the registered user. In step S41, the content display process is terminated. On the other hand, if it is determined that the registered user who executed the access request does not have access right to the content (NO), is an error displayed using the browser function of the PC terminal 60 of the registered user? Alternatively, the content display process is terminated without displaying anything (step S42).

  FIG. 11 is a content display example in which the first modification (steps S41 to S42) of the content display process for the registered user C is executed with the content as a page or frame in the Web page. Since the registered user C has access rights to the contents 1 and 3 and does not have access rights to the contents 2 and 4, the contents 1 of the registered user A who publishes the contents (san's diary) Is displayed, and the content 3 (7/2 (Tue) diary) is displayed on the content 1. On the other hand, the contents 2 (7/1 (Monday) diary) and the contents 4 (7/3 (Wednesday) diary) are not displayed.

<Modification 2 of content display processing>
Modification 2 of the content display process will be described with reference to FIGS. FIG. 12 is a flowchart for executing the modification 2 of the content display process. FIG. 13 is a content display example in which the modification example 2 of the content display process is executed.

  In the second modification, unlike the content display example of FIG. 9, first, the contents that all registered users have access rights are displayed. In addition, headings are displayed for content that is not content to which all registered users have access rights. Then, when the registered user clicks on the heading of the content having the access right, the content of the content having the access right is accessed, and the content of the content is displayed using the browser function of the PC terminal 60 of the registered user.

  In the modification 2 of the content display process, first, the registered user who has executed the access request performs the process on the content based on the information transmitted to the PC terminal 60 by the content display process (step S14) of the content server 40. It is determined whether or not the user has an access right (step S50). If it is determined in step S50 that the registered user who has executed the access request has access right to the content (YES), the content having the access right is displayed using the browser function of the PC terminal 60 of the registered user. Then, the content display process is terminated (step S51). On the other hand, when it is determined that the registered user who executed the access request does not have access right to the content (NO), an error is displayed using the browser function of the PC terminal 60 of the registered user, or Without displaying anything (step S52), the content display process is terminated.

  FIG. 13 is a content display example in which the modification 2 (steps S51 to S52) of the content display process for the registered user C is executed with the content as a page or frame in the Web page. Since the registered user C has access rights to the contents 1 and 3 and does not have access rights to the contents 2 and 4, the contents 1 of the registered user A who publishes the contents (san's diary) Is displayed, and the heading of the content 3 (7/2 (Tue) diary) is displayed on the content 1. On the other hand, headings of content 2 (7/1 (Monday) diary) and content 4 (7/3 (Wednesday) diary) are not displayed.

  When the heading of the content 3 is clicked, the content 3 is accessed and displayed using the browser function of the PC terminal 60 of the registered user C.

The communication portable terminal 10 includes biometric information of a registered user who is a terminal user and personal attribute data such as the age of the registered user for the access right setting change control executed by the content server 40. It is an apparatus that transmits status data to the content server 40. The main process performed by the communication portable terminal 10 which is a status communication apparatus will be described with reference to FIG.

  In the main process of the communication portable terminal 10, first, an initialization process for initializing variables and flags used in the process is executed (step S100). Then, sensors such as the heart rate sensor 28, the temperature sensor 29, and the humidity sensor 30 of the communication portable terminal 10 are activated (step S101). When each sensor measures its measured value, it immediately transmits the measured value to the CPU 22. Here, the interval at which each sensor transmits the measurement value to the CPU 21 is set to a predetermined interval (for example, an interval of 5 seconds).

  After executing the activation process (step S101) of each sensor, the terminal user sensing process is activated (step S102), and the terminal surrounding sensing process is activated (step S103). The terminal user sensing process will be described later with reference to FIG. 15, and the terminal surrounding sensing process will be described later with reference to FIG.

  After starting the terminal user sensing process and the terminal surrounding sensing process (steps S102 to S103), it is determined whether or not the user update flag is set to “1” (step S104). Here, the “user update flag” means that the registered user who is the user of the terminal 10 measures the heart rate, body temperature, sweating amount, and the like of the registered user with the sensor of the terminal 10 and changes to “1” when the measured value changes. When the measured value does not change, the flag is set to “0”. Initialization and change of the user update flag is executed by a terminal user sensing process (FIG. 15) described later.

  When it is determined in the user update flag determination process (step S104) that the user update flag is set to “1” (YES), the measured value measured by the sensor has changed, so that the terminal use A person situation inference process is executed (step S105). The terminal user situation inference process will be described later with reference to FIG.

  After executing the terminal user situation inference process (step S105), the situation information transmission process for transmitting the situation information from the communication portable terminal 10 to the content server 40 as the situation data constituting a part of the attribute information of the registered user is executed. (Step S106), the process proceeds to Step S107. In addition, position / location information and time information are also added to the situation information transmitted by the situation information transmission process (step S106). In addition, the interval at which the status information is transmitted to the content server 40 is set every predetermined interval (for example, every several seconds), but is not limited to this. It is also possible to set so that status information is transmitted when a call is made to the server 40 (for example, when an access request to content is made).

  On the other hand, if it is determined in the user update flag determination process (step S104) that the user update flag is not set to “1” (NO), whether or not the surrounding update flag is set to “1”. Is determined (step S109). Here, the “ambient update flag” refers to the temperature, humidity, illuminance, volume, and the like indicating the ambient environment of the terminal 10 measured by the sensor of the terminal 10, and when the measured value changes, the measured value is “1”. This flag is set to “0” when it does not change. The initialization and change of the surrounding update flag is executed by a terminal surrounding sensing process (FIG. 21) described later.

  In the surrounding update flag determination process (step S109), when it is determined that the surrounding update flag is set to “1” (YES), since the measurement value measured by the sensor has changed, the terminal surrounding state inference is performed. Processing is executed (step S110). The terminal surrounding situation inference process will be described later with reference to FIG.

  After executing the terminal surrounding situation inference process (step S110), a situation information transmission process for transmitting the situation information from the communication portable terminal 10 to the content server 40 as the situation data constituting part of the attribute information is executed (step S106). ), The process proceeds to step S107.

  When it is determined that the surrounding update flag is not set to “1” (NO) in the surrounding update flag determination process (step S109), the measured value measured by the sensor has not changed, so the status information Without proceeding to step S107.

  And it is judged whether the power supply of the communication portable terminal 10 is set to OFF (step S107). When it is determined that the power is set to OFF (YES), all the processes are terminated (step S108), and the main process of the communication portable terminal 10 is terminated. On the other hand, when it is determined that the power is not set to OFF (NO), the process returns to step S104 and the processes of steps S104 to S110 are repeated.

<< Terminal user sensing process >>
The terminal user sensing process according to the first embodiment detects changes in the heart rate, body temperature, and sweating amount by a sensor such as a heart rate sensor provided in the communication portable terminal 10, and the user is detected when changes are detected. Set the update flag to “1”. The change is detected by comparing data stored in the buffer 1 in which sensing data from each sensor is stored and the buffer 2 in which sensing data from each sensor that has already been detected is stored. . The terminal user sensing process will be described with reference to FIG.

  In the terminal user sensing process, first, all the sensing data (measured values) from each sensor stored in the storage area of the buffer 1 is deleted (step S111), and the CPU 22 waits until receiving the sensing data from each sensor. (Step S112). Specifically, when it is determined in step S112 that no sensing data has been received (NO), it is possible to wait until sensing data from each sensor is received by repeating the processing in step S112.

  On the other hand, when the CPU 22 determines that the sensing data has been received (YES) in step S112, the sensing data is stored in the storage area of the buffer 1 (step S113). Then, the CPU 22 determines whether or not the sensing data from all the sensors has been obtained and stored in the storage area of the buffer 1 (step S114).

  If it is determined in step S114 that sensing data from all the sensors has not been acquired and stored (NO), the process returns to step S112, and the processes in steps S112 to S114 are repeated. On the other hand, when it is determined that sensing data from all the sensors is acquired and stored (YES), the sensing data from each sensor stored in the storage area of the buffer 1 and the storage area of the buffer 2 are stored. It is determined whether or not the stored sensing data matches (step S115).

  In step S115, when it is determined that the sensing data from each sensor stored in the storage area of the buffer 1 matches the sensing data stored in the storage area of the buffer 2 (YES) Since it is not necessary to change the person update flag, the process returns to step 111 and the processes of steps S111 to S115 are repeated.

  On the other hand, when it is determined in step S115 that the sensing data from each sensor stored in the storage area of the buffer 1 and the sensing data stored in the storage area of the buffer 2 do not match (NO). Then, the sensing data stored in the buffer 1 is stored in the buffer 2, a user update flag indicating that the storage area of the buffer 2 has been updated is set to “1” (step S116), and the process returns to step S111.

  If it is determined in step S425 that the illuminance sensing data is not less than 5000 lx (NO), it is determined whether the illuminance sensing data is less than 50000 lx (step S427). If it is determined in step S427 that the illuminance sensing data is less than 50000 lx (YES), “4” is set to the variable LIGHT (step S428), the illuminance classification process is terminated, and the process returns to the terminal surrounding situation inference process. . LIGHT = 4 indicates that the illuminance is high.

  Furthermore, when it is determined in step S427 that the illuminance sensing data is not less than 50000 lx (NO), “5” is set to the variable LIGHT (step S429), the illuminance classification process is terminated, and the terminal surrounding situation inference process Return to. LIGHT = 5 indicates that the illuminance is very high.

  After the above illuminance classification process (step S325) is completed, the process returns to the terminal surrounding situation inference process, and the volume classification process is executed (step S326).

<Volume classification processing>
The volume classification process (step S326) will be described with reference to FIG. FIG. 27 is a flowchart for executing volume classification processing. First, in the volume classification process, it is determined whether or not the volume sensing data (measured value of the sound sensor 32) stored in the buffer 2 is less than 10 db (step S431).

  If it is determined in step S431 that the volume sensing data is less than 10 db (YES), “1” is set in the variable VOL (step S432), the volume classification process is terminated, and the terminal surrounding situation inference process is performed. Return to. VOL = 1 indicates that the volume is very low.

  If it is determined in step S431 that the volume sensing data is not less than 10 db (NO), it is determined whether the volume sensing data is less than 40 db (step S433). If it is determined in step S433 that the volume sensing data is less than 40 db (YES), “2” is set in the variable VOL (step S434), the volume classification process is terminated, and the process returns to the terminal surrounding inference process. VOL = 2 indicates that the volume is low.

  If it is determined in step S433 that the sound volume sensing data is not less than 40 db (NO), it is determined whether or not the sound volume sensing data is less than 70 db (step S435). If it is determined in step S435 that the volume sensing data is less than 70 db (YES), “3” is set in the variable VOL (step S436), the volume classification process is terminated, and the process returns to the terminal surrounding situation inference process. . VOL = 3 indicates that the volume is normal.

  If it is determined in step S435 that the sound volume sensing data is not less than 70 dbx (NO), it is determined whether the sound volume sensing data is less than 100 db (step S437). If it is determined in step S437 that the volume sensing data is less than 100 db (YES), “4” is set in the variable VOL (step S438), the volume classification process is terminated, and the process returns to the terminal surrounding situation inference process. . VOL = 4 indicates that the volume is high.

  Furthermore, when it is determined in step S437 that the volume sensing data is not less than 100 db (NO), “5” is set to the variable VOL (step S439), the volume classification process is terminated, and the terminal surrounding situation inference process is performed. Return to. VOL = 5 indicates that the volume is very high.

  After completing the above volume classification process (step S326), the process returns to the terminal surrounding situation inference process and proceeds to step S327.

<Situation reasoning value calculation processing>
In the situation reasoning value calculation process (step S327) of the terminal surrounding situation inference process (FIG. 22), the variable TEMP2 determined by the temperature classification process (step S323) and the variable HUMID determined by the humidity classification process (step S324) , Using the variable LIGHT determined by the illuminance classification process (step S325), the variable VOL determined by the volume classification process (step S326), and the terminal ambient situation inference table stored in the hard disk 21, Is calculated and stored in the RAM 23.

  The terminal surrounding situation inference table will be described with reference to FIG. FIG. 23 is an example of the terminal surrounding situation inference table used in the situation inference value calculation process (step S327) of the terminal surrounding situation inference process (FIG. 22). In the terminal surrounding situation inference table (FIG. 23), the environmental condition of the terminal user is “sultry daytime” (situation inference value = 1) when TEMP2 is 5, HUMID is 4, and LIGHT is 4-5. Is the case. The environmental condition of the terminal user is “noisy indoors” (situation inference value = 2) when TEMP2 is 2 to 4, HUMID is 2 to 3, LIGHT is 2 to 3, and VOL is 5. . The terminal user's environmental state is “cold night” (situation inference value = 3) when TEMP2 is 1-2 and LIGHT is 1-2. When the combination of the three variables does not correspond to any of the above cases, the environmental condition of the terminal user is “normal” (situation inference value = 0).

<Situation reasoning value judgment processing>
When the situation reasoning value calculation process (step S327) is executed, the situation reasoning value is stored in the RAM 23, and the CPU 22 judges whether or not the situation reasoning value stored in the RAM 23 is “1” or more. A value determination process is executed (step S328). In the situation inference value determination process (step S328), when the situation inference value is not “1” or more (NO), that is, when it is determined as “normal” by the situation inference value, the process returns to step S322, and the situation inference value is “ As long as it is “0”, the processing of steps S322 to S328 is repeated. Accordingly, the situation information corresponding to the situation inference value “0” is transmitted from the communication portable terminal 10 to the content server 40 by the situation information transmission process (step S106) of the main process (FIG. 14) of the communication portable terminal 10 which is the situation communication device. Never sent.

  On the other hand, when it is determined that the situation inference value is “1” or more (YES) in the situation inference value determination process (step S328), the situation inference values “1” to “3” of the environmental state stored in the RAM 23 are stored. ”, For example, environment information is acquired from the hard disk 21 and a situation inference value update process for updating the situation inference value is executed (step S329), and the terminal user situation inference process is terminated. Returning to the processing (FIG. 14), the status information transmission processing is executed (step S106). Accordingly, any of the situation inference values “1” to “3” is transmitted from the communication portable terminal 10 to the content server 40 by the situation information transmission process (step S106) of the main process (FIG. 14) of the communication portable terminal 10 which is the situation communication device. The status information (environment information) corresponding to the value can be transmitted.

  Therefore, according to the content access control system according to the first embodiment, the content server 40 extracts the attribute information indicating the content of the content that satisfies the attribute condition for extracting the attribute information for all the content. Extracted as (access permission list) and stored in the extracted information storage unit 55. On the other hand, the attribute information of the registered user who uses the communication portable terminal 10 is stored in the user information storage unit 56. Therefore, the access control unit 57 can dynamically change the setting of the access right of the registered user who can access the content based on the result of comparing the registered user attribute information and the extracted attribute information.

  In addition, since the access right is dynamically changed, a registered user who accesses his / her content can cause the desired registered user to access his / her content. As a result, it is possible to save the trouble of changing the setting of the access right for each content for the registered user who accesses the content.

  Furthermore, a registered user accessing the content can access the content desired by the user. In particular, since the setting of the access right is dynamically changed based on the registered user attribute information, it is possible to access the desired content reflecting the changing registered user attribute information.

  In particular, according to the content access control system according to the first embodiment, since it is possible to change the setting of access rights based on the attribute information of the registered user reflecting the status data such as the biometric information of the terminal user, the terminal You can change the access right settings linked to the user status data. As a result, according to the changing status of registered users, even if the access right is set for each part of the content instead of changing the access right setting for the entire content, the user's effort is saved, You can change the access right settings.

<<<<< Second Embodiment >>>>
The content access control system according to the first embodiment is a situation management table configured based on the situation information transmitted from the communication portable terminal 10 to the content server 40 each time an access request for the content is made by a registered user (see FIG. 6) and the extracted attribute information (access permission list (FIG. 6) extracted from the registered user attribute information and the attribute information indicating the content of the content that satisfies the attribute conditions for extracting the attribute information for all the contents. The access control unit 57 of the content server 40 compares the attribute information indicating the contents stored in 7)) with the access control unit 57 of the content server 40 to determine whether the registered user has access rights to the content. Therefore, in order to determine the presence or absence of the access right, the attribute information of the registered user stored in the situation management table (FIG. 6) and the attribute information indicating the content content stored in the access permission list (FIG. 7) are used. Each time an access request is made to the content from the registered user, it is necessary to make a judgment on each attribute information, and as a result, a large calculation load and judgment time are required for the content server 40. .

  In order to solve the problem of the system according to the first embodiment, the content access control system according to the second embodiment stores, as an access list, the result of determining whether or not the registered user has access rights to the content for each content. Therefore, the calculation load and the determination time of the process for determining whether or not the registered user has the access right to the content are reduced. Here, the “access list” is a table list that stores, for each content, the result of determining whether or not the registered user has access rights to the content.

  The control processing in the system according to the first embodiment and the system according to the second embodiment is the same including the content display example, except for the flowchart of the main processing of the content server 40 (FIG. 3). For example, the content display process executed in the PC terminal 60 of the content access control system according to the second embodiment includes the content display process of the first embodiment (FIGS. 8 to 9) and the content display process of the first modification (FIG. 10 to 11) and any one of the content display processes of the second modification (FIGS. 12 to 13) can be applied.

  The main process of the content server 40 of the content access control system according to the second embodiment will be described below with reference to FIGS. FIG. 28 is a flowchart for executing main processing of the system according to the second embodiment. FIG. 29 shows an access list.

<<< Control processing of content server 40 >>>
<< Main processing >>
The main process of the content server 40 according to the second embodiment will be described with reference to FIG. In the content server 40 of the content access control system according to the second embodiment, the determination is made by referring to the access list in order to determine whether or not the registered user has access rights to the content.

  First, the content server 40 determines whether there is a request for access to the content of the registered user from the PC terminal 60 to the content server 40 (step S510). In step S510, when it is determined that there is an access request (YES), the access list (FIG. 29) is referred to and whether or not the registered user who has made the access request has set the access right for each content. Judgment is made (step S511).

  In step S511, after finishing the access right setting determination process, a content display process for displaying the content for which the access right is set by the browser function of the PC terminal 60 of the registered user is executed (step S512). .

  Then, it is determined whether or not the power of the content server 40 is set to OFF (step S513). When it is determined that the power is set to OFF (YES), all the processes are finished and the main process of the content server 40 is finished. On the other hand, when it is determined that the power is not set to OFF (NO), the process returns to step S510, and the processes of steps S510 to S518 are repeated.

  On the other hand, when it is determined in step S510 that there is no access request (NO), it is determined whether or not there is a change in attribute information configured from the situation information transmitted from the communication portable terminal 10 (step S514). If it is determined in step S514 that the attribute information is changed (YES), an access list update process for updating the access list is executed (step S515), and the process proceeds to step S516. On the other hand, if it is determined in step S514 that there is no change in the attribute information (NO), the process proceeds to step S516 without updating the access list.

  In step S516, it is determined whether or not the content is changed (step S516). If it is determined in step S516 that the content is changed (YES), an analysis process (FIG. 4) is executed (step S517), and an access list update process for updating the access list is executed (step S518). The process proceeds to S510. On the other hand, if it is determined in step S516 that there is no change in the content (NO), the process proceeds to step S510 without updating the access list.

The access list is a table list in which the result of determining whether or not the registered user has access rights to the content is stored for each content. In the access list of FIG. 29, “O” indicates that the user has the right to access the content, and “X” indicates that the user does not have the right to access the content.

  Therefore, a content access control system according to the second embodiment that determines, for each content, whether or not there is an access right to the registered user's content by referring to an access list that is a result of determining whether or not the registered user has access to the content. Each time an access request is made for content, the registered user attribute information stored in the status management table (FIG. 6) and the attribute information indicating the content content stored in the access permission list (FIG. 7) are displayed.
