May be sent out to indicate that access is denied.

  The content management apparatus 100 further includes a user storage unit 120. The user storage unit 120 holds terminal identification data for each security level.

  When the security level of the user portable terminal 200 does not satisfy the security level of the free use area FUA where the user portable terminal 200 that requests the content is located, the access execution unit 180 accesses the user portable terminal 200 that requests the content. Access denial information indicating that permission is not allowed may be sent.

  When the user portable terminal 200 is permitted to access the content, the determination unit 130 associates the identification data of the permitted content with the portable terminal identification data of the user portable terminal 200 that is permitted to access the content. May be updated.

  More specifically, as shown in FIG. 3, the free address office FAO is set so that the free address user FAY is freely located in a plurality of free use areas FUA as described above. The free address user FAY is, for example, an employee who works for the free address office FAO.

  The free use area FUA includes, for example, a seat and a conference room where the free address user FAY is freely located. The free address user FAY located in the free address office FAO always has the user portable terminal 200.

  This user portable terminal 200 can individually detect the free address user FAY by the user detection device 300 at least for each free use area FUA.

  The free use area FUA is an office divided into predetermined sections, and an area ID for identifying each free use area FUA is registered in the content management apparatus 100.

  FIG. 2 is a diagram showing a content management system 1000 including the content management apparatus 100 of the present embodiment. The content management apparatus 100 is connected to the user portable terminal 200 and the user detection device 300 via a communication network. The communication network is, for example, a wireless LAN, a LAN, or the Internet.

  The user portable terminal 200 includes a PDA 210, a PHS terminal 220, a mobile computer 230, and the like. In the user portable terminal 200, a terminal ID, a telephone number, a mail address, and the like for each free address user FAY are individually set or registered.

  As shown in FIG. 3, for example, the PHS base station 320 and the access point 330 are installed on the ceiling or the like for each free use area FUA, for example.

  The content management apparatus 100 includes a database server of a free address office FAO to which the above-described various user detection devices 300 are connected. In the content management apparatus 100, the above-described units 110 to 110 are realized as various functions by executing various processing operations corresponding to the installed computer program.

  Next, the specific units 110 to 110 of the content management apparatus 100 will be described.

  The area storage unit 110 stores area IDs for individually identifying a plurality of free use areas FUA for each security level.

  The user storage unit 120 stores user IDs for individually identifying a plurality of free address users FAY for each security level. The user storage unit 120 stores a user ID and a terminal ID of a user portable terminal carried by the user in association with each other. The user ID is, for example, an employee number or an email address. The terminal ID is, for example, a serial number or a telephone number of the user portable terminal, and may be an arbitrarily assigned identification number.

  The content storage unit 140 stores content IDs for individually identifying a plurality of contents for each security level. The content is, for example, a document file, an image file, audio data, or the like. The content ID may be a file name, an extension for identifying a file format, or metadata representing a file attribute.

  The security level is an index indicating the confidentiality of business. For example, the security level may be determined for each department such as a research department, a development department, or a sales department, or a security level may be determined for each position.

  The user detection unit 150 detects where the user portable terminal 200 carried by the free address user FAY is located in the free use area FUA. For example, the terminal ID for each free address user FAY is detected in association with the area ID. Further, the user ID may be detected in association with the area ID.

  The current status holding unit 160 temporarily holds the user detection result detected by the user detection unit 150. Specifically, the user detection result is obtained by temporarily holding the terminal ID and the area ID in association with each other.

  Further, the current status holding unit 160 refers to the user storage unit 120, extracts the user ID corresponding to the terminal ID and its security level, and stores the user ID in association with the user detection result. On the other hand, when the user detection unit 150 detects the user ID in association with the area ID, the current status holding unit 160 refers to the user storage unit 120, extracts the security level corresponding to the user ID, and corresponds to the user detection result. You may hold it.

  Further, the current status holding unit 160 refers to the area storage unit 110, reads the security level of the detected area ID, and stores the security level in association with the user detection result. FIG. 4 is a diagram illustrating an example of the data structure of the current status holding unit 160.

  The access receiving unit 170 receives a request for content from the user portable terminal 200. Specifically, a terminal ID that requests content and a content ID that identifies the content are received in association with each other. A request for content can be accepted via the user detection device 300.

  The determination unit 130 refers to the content storage unit 140 and reads the security level corresponding to the content ID received by the access reception unit 170. Further, the security level of the free use area FUA corresponding to the terminal ID received by the access receiving unit 170 is read with reference to the user detection result temporarily stored in the current status holding unit 160. The security level of the read content and the security level of the free use area FUA are compared, and it is determined whether or not the security level of the free use area FUA satisfies the security level of the content.

  As a determination method, for example, there are the following methods. The security level is quantified as 1 to 5. The larger the number, the higher the confidentiality. In this case, satisfying the security level means that the numerical value of the security level to be compared is larger than the numerical value of the reference security level. If the security level of a certain content (referred to as content A) is 3 and the security level of the free use area FUA (referred to as office A) is 5, the security level of office A satisfies the security level of content A To do. On the other hand, if the security level of the free use area FUA (referred to as office B) is 2, the security level of office B does not satisfy the security level of content A.

  When determining that the security level of the free use area FUA satisfies the security level of the requested content, the determining unit 130 allows the access execution unit 180 to access the requested content together with the terminal ID. Send permission signal.

  On the other hand, when the determination unit 130 determines that the security level of the free use area FUA does not satisfy the security level of the requested content, the access execution unit 180 indicates that access to the content cannot be permitted together with the terminal ID. Send access denial information.

  When the access execution unit 180 receives the access permission signal from the determination unit 130, the access execution unit 180 transmits the access permission signal to the user portable terminal 200 based on the terminal ID received together with the access permission signal. The user portable terminal 200 that has received the access permission signal can access predetermined content stored in the content management apparatus 100.

  Further, when the access execution unit 180 receives the access denial information from the determination unit 130, the access execution unit 180 transmits the access denial information to the user portable terminal 200 based on the terminal ID received together with the access denial information. The user portable terminal 200 that has received the access denial information displays the access denial information on a display, for example. Further, it may be called by voice that access to the content is denied. By outputting the warning information received from the content management apparatus 100 by the user portable terminal 200, the user can know that the security level of the content requested by the free use area FUA in which the user portable terminal 200 is located is not satisfied. .

  The determination unit 130 updates the user detection result held in the current state holding unit 160 when the access permission signal is transmitted. Specifically, either the terminal ID or the user ID included in the user detection result is associated with the content ID permitted to be accessed.

  When the use of the content ends, the user portable terminal 200 transmits an access end signal for ending access. The access reception unit 170 receives an access end signal together with the terminal ID and sends it to the determination unit 130. Based on the terminal ID, the determination unit 130 deletes the corresponding content ID included in the user detection result.

  Further, the user detection unit 150 detects the position of the user portable terminal carried by the free address user FAY at a predetermined interval in the free use area FUA, and the determination unit 130 detects the user based on the detection result. Update the result.

  The determination unit 130 refers to the user detection result held in the current state holding unit 160 and extracts data for each area ID. In the extracted free use area FUA, when there is a user portable terminal using the content, it is determined whether or not the security level of the user existing in the free use area FUA satisfies the security level of the content in use To do.

  Specifically, it is determined whether or not the security level corresponding to the content ID of the content in use satisfies the security level corresponding to the user ID.

  When there are a plurality of extracted user IDs, when the security level corresponding to at least one user ID does not satisfy the security level of the content in use, the determination unit 130 temporarily blocks access to the content. Is sent to the access execution unit 180 together with the terminal ID of the user portable terminal. The blocking signal may block the display on the display of the user portable terminal 200.

  In addition, the determination unit 130 may transmit warning information that warns that the security of the free use area FUA is deteriorated together with the blocking signal.

  When the access execution unit 180 receives the block signal and the terminal ID from the determination unit 130, the access execution unit 180 transmits the block signal to the user portable terminal 200 identified by the terminal ID. When the warning information is received, the warning information is also transmitted.

  Thereby, the display of content is temporarily interrupted on the display of the user portable terminal 200. When the warning information is transmitted, the warning information is displayed on the display of the user portable terminal 200. This warning information informs that there is a user who does not satisfy the security level of the content being executed in the free use area FUA that is being worked on. As a result, the user can ensure the security of the content in use by temporarily interrupting the work or encouraging the user who does not satisfy the security level to move.

  The content management apparatus 100 according to the present embodiment executes various processing operations corresponding to the computer program installed as described above, so that the above-described units 110 to 110 are realized as various functions. .

  Such a computer program includes, for example, content storage means for storing contents by security level, area storage means for storing each free use area by security level, and terminal identification data for identifying a user portable terminal for each free use area Terminal position detecting means for detecting the status, current status holding means for holding the detection result detected by the terminal position detecting means, content request accepting means for accepting a content request together with terminal identification data, and the content request means accepting from the detection result Extracting a free use area corresponding to the terminal identification data, determining means for determining whether the security level of the extracted free use area satisfies the security level of the requested content, and the requested content No cough When the security level satisfies the security level of the free use area where the user portable terminal requesting the content is located, the content management apparatus 100 executes access permission means for permitting the user portable terminal to access the requested content. It is described to let you.

  An example of a content management method performed by the content management apparatus 100 according to the present embodiment having the above-described configuration will be described below. First, the content management system 1000 of the present embodiment is used in the free address office FAO as described above.

  The free address office FAO is classified as, for example, a conference room in which a plurality of seats are a plurality of free use areas FUA. The free address user FAY who is an employee is not fixed in his / her seat, and freely uses the free use area FUA.

  For this reason, when handling highly confidential data, it is necessary to consider the free address user FAY seated in the vicinity. For example, when working with confidential material, if a free address user FAY of another department is seated next to the office, the work status will be in the field of view of the free address user FAY of the adjacent seat, which is a security problem. . However, in the content management system 1000 of this embodiment, the security level is managed for each free use area FUA and the user portable terminal 200.

  Each of the free address users FAY as described above has a user portable terminal 200 such as the PDA 210, the PHS terminal 220, the mobile computer 230, and the like.

  In this state, when the free address user FAY is seated in a desired free use area FUA, the PHS terminal 220 or the mobile computer 230 of the free address user FAY receives the PHS base station 320 or access point 330 of the free use area FUA. To access. As a result, the user ID and terminal identification data are detected by the PHS base station 320 and the access point 330.

  In the user storage unit 120, a user ID and a terminal ID are stored in association with each other. Therefore, the user detection unit 150 may detect the terminal ID by detecting only the user ID. Further, the user ID may be detected by detecting the terminal ID. Moreover, you may employ | adopt the structure which can detect both user ID and terminal ID. That is, it is only necessary to detect either the user ID or the terminal ID for each free use area FUA. When a user has a plurality of user portable terminals 200, security management can be performed for each user portable terminal.

  At this time, whenever the PHS terminal 220 or the mobile computer 230 of the free address user FAY is detected by the PHS base station 320 or the access point 330 in the free use area FUA (step S1), as shown in FIG. The relationship is temporarily held (step S2). Specifically, the terminal ID, the user ID, and the area ID of the free use area FUA are stored in association with each other. When the content management apparatus 100 receives a request for content together with the terminal ID from the user portable terminal 200 (step S3), the area corresponding to the terminal ID of the user portable terminal 200 that requested the content from the temporarily stored detection result. By reading the ID, the security level of the free use area FUA where the user portable terminal is located is grasped. Referring to user storage unit 120 and area storage unit 110, it is determined whether or not the security level corresponding to the terminal ID satisfies the security level of the free use area FUA in which the terminal is located (step S4). If the security level is satisfied (Y in step S4), the content management apparatus 100 transmits an access permission signal to the user portable terminal 200 that has requested the content (step S5). If the security level is not satisfied (N in step S4), access denial information is transmitted (step S6). The access rejection information is information for displaying on the display of the user portable terminal 200 that the content cannot be accessed because the free use area FUA in which the user portable terminal 200 is located does not satisfy the requested security level of the content. .

  When the user portable terminal 200 receives the access permission signal, the user can work using the content. In addition, the user portable terminal displays the access denial information on the display, for example, by accepting the access denial information, and the user can know that his / her location is inappropriate for security as an area where the content is used. .

  Further, as shown in FIG. 6, every time the PHS terminal 220 or the mobile computer 230 of the free address user FAY is detected by the PHS base station 320 or the access point 330 in the free use area FUA (Y in step S7), the current situation Is temporarily held (step S8). If the user is permitted to access the content (Y in step S9), the user ID and the security level of the content for which access is permitted are stored in association with each other (step S10). A user ID located in the same free use area as the free use area where the user who is permitted to access the content is extracted, and the security level of the extracted user is compared with the security level of the content for which access is permitted. If the security level of at least one user ID among the extracted user IDs does not satisfy the security level of the content being accessed (Y in step S11), a blocking signal is transmitted to the user portable terminal that is accessing the content Then, the content is not displayed on the display of the portable terminal (step 12). Further, warning information may be transmitted.

  A specific example of the operation of the content management apparatus 100 will be described below with reference to FIGS.

  The content management apparatus 100 detects that there are users, patent Taro and patent Hanako, in the office A, and temporarily stores the detection result in the current status holding unit 160. The current status holding unit 160 refers to the user storage unit 120, reads that the user portable terminal carried by the patent Taro is computer1, and that the user portable terminal carried by the patent Hanako is the computer2, and associates it with the detection result. Hold.

  Patent Taro operates computer 1 and requests content A from content management apparatus 100. The access receiving unit 170 receives information that there is a request for content A from the computer 1 and sends it to the determining unit 130. The determination unit 130 reads from the current status holding unit 160 that the location of computer1 is in office A, extracts office A from the area storage unit 110, and reads that the security level is 4. Further, the determination unit 130 extracts the content A from the content storage unit 140 and reads that the security level of the content A is 2. Assuming that the higher the security level is, the higher the confidentiality is, the security level of office A satisfies the security level of content A. Therefore, the determination unit 130 instructs the access execution unit 180 to transmit an access permission signal to the content A. In addition, the determination unit 130 updates the current state holding unit 160 and adds data indicating that the computer 1 is operating the content A. The access execution unit 180 transmits an access permission signal to computer1. Thus, Taro Patent can operate computer 1 and use content A.

  Patent Hanako operates computer 2 to cause the content management apparatus 100 to request content B. The access receiving unit 170 receives information that there is a request for content B from the computer 2 and sends it to the determining unit 130. The determination unit 130 reads from the current status holding unit 160 that the location of computer2 is in office A, extracts office A from the area storage unit 110, and reads that the security level is 4. Further, the determination unit 130 extracts the content B from the content storage unit and reads that the security level of the content B is 5. If the security level is higher and the confidentiality is higher, the security level of the office A does not satisfy the security level of the content B. Therefore, the determination unit 130 instructs the access execution unit 180 to transmit an access denial signal, and the access execution unit 180 transmits an access denial signal to computer2. Thereby, Hanako can know that the content B cannot be handled in the office A.

  Subsequently, the content management apparatus 100 detects that there is a user Jojiro as a user in the office A, and the current status holding unit 160 adds the detection result to the detection result.

  The determination unit 130 determines the degree of satisfaction of the security level of the user ID detected for each free use area every time the current status holding unit 160 is updated. The detection result held in the current status holding unit 160 is updated by detecting the user ID of Jojiro Jiro. The determination unit 130 refers to the user storage unit 120, reads that the security level of Jojiro is 1, and determines that the security level of the content A used by Taro in the office A is not satisfied. Therefore, the determination unit 130 instructs the computer 1 that is accessing the content storage unit 140 to transmit a signal for blocking the display of the content A to the access execution unit 180. Further, the determination unit 130 instructs the access execution unit 180 to transmit warning information together.

  By constantly executing the processing operations as described above, it is possible to ensure the security of the content executed in the free address office FAO.

  According to the content management apparatus 100, the free use area FUA, the user portable terminal, and the content are managed according to the security level, and it is determined that the position of the user portable terminal that uses the content satisfies the content security level. Can be allowed. Thereby, the security of the content used for each free use area FUA can be managed.

  Further, according to the content management apparatus 100, when the security level of the free use area where the user is located does not satisfy the requested security level of the content, the access denial information can be transmitted. This access refusal information indicates that the free use area does not satisfy the security of the requested content. As a result, the user can know that the free use area where he / she is located does not meet the security level of the content he / she wants to use, and can continue to work by moving the free use area or requesting different content. Can do.

  Further, the content management apparatus 100 may manage the user portable terminals according to security levels. In this way, user portable terminals that can be used in the free use area can be managed according to the security level. When the security level of the user portable terminal does not satisfy the security level of the free use area, access denial information indicating that access to the content cannot be permitted is transmitted to the user portable terminal. This access information indicates that the user portable terminal does not satisfy the security level of the free use area. Thereby, the user can know that his / her user portable terminal does not satisfy the security level of the free use area, and can change the terminal to be used to a user portable terminal that satisfies the security level. it can.

  Further, according to the content management apparatus 100, the free use area FUA, the user, and the content are managed according to the security level, and it is determined that the location of the user who uses the content satisfies the security level of the content. Can be displayed on the display. Thereby, the security of the content used for each free use area FUA can be managed.

  Moreover, according to the content management apparatus 100, when transmitting content, it is possible to store the security level of the content to be transmitted in association with the user information of the user portable terminal 200 that is the content transmission destination. Thereby, it can be grasped in real time whether the situation around the user satisfies the security level of the content.

  For example, when a user who does not satisfy the content security level is detected in the free use area that transmits the content display information, the display block that blocks the content display to the user mobile terminal that transmits the content display information A signal can be transmitted.

  Further, in this case, warning information for warning that the security of the free use area is lowered can be transmitted and displayed on the user portable terminal.

  As described above, according to the content management apparatus 100, the access right can be controlled in accordance with the location and the surrounding situation.

  For example, highly confidential content can be accessed only in a specific location (confidential area).

  In addition, if there is an outsider who does not satisfy the security level, the content cannot be displayed.

  As described above, since it becomes possible to limit the work space for confidential work, safety can be ensured even in an office where a large number of people come and go, such as a free address office.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention.

  In the above embodiment, a plurality of user portable terminals 200 are composed of the PDA 210, the PHS terminal 220, and the mobile computer 230, and the user detection device 300 is composed of the PHS base station 320 and the access point 330.

  However, as the user portable terminal 200, an infrared receiver connected to the mobile computer 230, and as the user detection device 300, an infrared transmission that transmits an individual ID for each individual or an area ID for each free use area FUA to the infrared receiver. A vessel, etc. can also be used (not shown).

  Such an infrared transmitter is attached to, for example, a fluorescent lamp on the ceiling of a free use area FUA, and converts the emitted light into electric power to transmit the registered individual ID and area ID by infrared.

  Then, the infrared receiver that has received this causes the individual ID and area ID to be transmitted from the mobile computer 230 to the content management apparatus 100 via a wireless LAN or the like. Therefore, the content management apparatus 100 can also recognize the position of the free address user FAY.

  Moreover, in the said form, only the content management apparatus 100 illustrated in real time detecting the use condition of the free use area FUA by the free address user FAY. However, the content management apparatus 100 as described above may further include an action registration unit (not shown) that accepts registration of the action schedule data of the free address user FAY into the area management data.

  Similarly, use registration means for accepting registration of use schedule data of the free use area FUA in the area management data may be further included. In these cases, for example, a schedule for the free address user FAY or the free use area FUA is registered by a so-called scheduler, and the schedule is reflected in the user list image or the area list image. The user list image is to display the data structure of the detection result held by the current status holding unit 160 on the display in the portable terminal.

  Then, by confirming the user list image and the area list image, the use contents of the free use area FUA by the free address user FAY can also be confirmed.

  Further, in the present embodiment, the case where there are a plurality of security levels is illustrated. However, the security level may be one.

  Furthermore, in the present embodiment, it has been exemplified that each unit of the content management apparatus 100 is logically realized as various functions by a computer program. However, each of these units can be formed as unique hardware, or can be realized as a combination of software and hardware.

  Needless to say, the above-described embodiment and a plurality of modifications can be combined within a range in which the contents do not conflict with each other. Further, in the above-described embodiments and modifications, the structure of each part has been specifically described, but the structure and the like can be changed in various ways within a range that satisfies the present invention.

  For example, the content management apparatus 100 according to the embodiment shown in FIG. 1 may manage content by the method shown in FIG.

  The access execution unit 180 outputs content display information to the user portable terminal 200 (S101). The user detection unit 150 individually identifies the user portable terminal 200 outputting the content display information and detects the position of the user portable terminal 200 (S102). Further, the user detection unit 150 detects the position of the guest in the free use area FUA (S103). The determination unit 130 detects the positional relationship between the position of the user portable terminal 200 detected by the user detection unit 150 and the position of the guest. Specifically, for example, the determination unit 130 calculates a distance between the position of the user portable terminal 200 and the position of the guest (S104). When the distance between the position of the user portable terminal 200 calculated by the determination unit 130 and the guest position is equal to or smaller than a predetermined interval (set distance) (Y in S105), the access execution unit 180 Then, the output of the content display information is blocked (S106).

  By doing so, even when a guest visits a free use area, it is possible to ensure the security of work using the content.

  Further, when the display information of the content is blocked, warning information for warning that the guest is approaching a predetermined distance may be output and displayed on the display.

  In this way, the user who is working can know that the guest is approaching, and can resume the work by calling attention to the guest.

  When the guest carries the PHS terminal, the user detection unit 150 can detect the position of the guest via the PHS base station. Further, when the guest carries the infrared tag, the position of the guest may be detected via a wide-angle camera having imaging sensitivity for infrared light. That is, the guest may be detected using various devices that can detect the guest position in distinction from the user. The guest may be another user.

  In the example of FIG. 4, when the user detection unit 150 detects the position of the computer 1 of the patent Taro and the position of the patent Jiro where the content is provided, the security level of the patent Taro and the patent are referred to the current status holding unit 160. Jiro's security level may be compared. At this time, when the distance between the position of computer1 detected by the user detection unit 150 and the position of Jiro Jiro is calculated, and the distance between computer1 and Jiro Jiro is less than a predetermined interval, the access execution unit 180 may block the output of content display information to computer1.

  The determination unit 130 detects the positional relationship between the position of the user portable terminal 200 and the guest position. Moreover, you may detect the positional relationship between the user portable terminals 200. FIG. Specifically, the determination unit 130 detects whether or not the guest has entered a predetermined range centering on the display of the user portable terminal 200. The predetermined range can be set to a distance at which the display can be seen. By doing so, when the guest (or user) approaches a distance set toward the user, the output of the display information of the content is blocked, and the content is temporarily not displayed on the display of the portable terminal.

  Therefore, business security can be ensured among users who use the free use area, and highly confidential business operations can be performed.

  Note that the mobile terminal that provides the content is not limited to the mobile terminal, and may be a desktop computer.

  Further, the content management apparatus 100 according to the present embodiment individually identifies, for example, an output unit that outputs content display information to a user portable terminal and a user portable terminal that outputs the content display information using a computer program. The user position detecting means for detecting the position of the user portable terminal, the guest position detecting means for detecting the position of the guest in the free use area, the position of the user portable terminal detected by the user position detecting means, and the guest position detection A positional relationship detecting means for calculating a distance between the guest position detected by the means and the distance between the user portable terminal calculated by the positional relationship detecting means and the guest position is equal to or less than a predetermined interval. At this time, the output unit may be configured to block the output of the display information of the content to the user portable terminal.
