[0001]
BACKGROUND OF THE INVENTION
The present invention is a location authentication system for authenticating location information acquired by the terminal device by communicating information between the terminal device and the location management device, a terminal device and a location management device for realizing such authentication, In addition, the present invention relates to a terminal device that authenticates acquired position information.
[0002]
[Prior art]
Information registration devices and information retrieval devices for digitizing information such as memos and photographs and storing and registering them in a semiconductor memory, etc., and retrieving the registered information for use as required are widely used.
Since such a device can register a huge amount of information, various inventions have been made on how to efficiently extract information from this huge amount of registered information.
[0003]
For example, in the invention described in Japanese Patent Application Laid-Open No. 8-287143, the registration information is managed by adding the generation date and time information of the information to the registration information.
In the invention described in Japanese Patent Laid-Open No. 8-50594, the latitude and longitude information calculated from the address book and the current position information of the device are combined to search for and provide appropriate map information. ing.
[0004]
Further, in the invention described in PEPYS ("PEPYS: Generating Autobiographies by Automatic Tracking," Proceedings of the Second European Conference on Computer-Supported Cooperative Work, Amsterdam, September 1991), the location information of the terminal device is specified, Therefore, it is estimated what kind of activity was performed and automatically sending a diary so that the position of the user is detected and recorded as a record.
[0005]
In recent years, with the development of computers and networks, information anywhere in the world can be easily obtained.
However, being able to easily obtain information often hinders the intention of actually going to the place and trying to be in a similar environment. That is, it can be seen that the convenience of easily acquiring information hinders the opportunity to obtain various experiences.
[0006]
From this point of view, the information registration and information retrieval devices described above have been designed for the convenience of using the registered information, and only when placed in the physical environment where the information is actually registered. The registration information cannot be used, and such a form of use hinders the motive to actually go there.
[0007]
Therefore, in view of such circumstances, the user can be motivated to try to put himself / herself in the physical environment in which the information is actually registered. Devices have been developed that can provide an opportunity to gain experience.
[0008]
For example, in the invention described in Japanese Patent Application No. 2000-188838 and the invention described in Japanese Patent Application No. 2000-192732, an information registration device for registering information such as a memo or a photograph together with information indicating the environment at the time of registration, For example, an information retrieval device that retrieves information registered in this manner is provided. For example, an individual's thoughts and impressions when placed in a specific environment are recorded and registered in association with the environment. Later, an apparatus that can retrieve the registration information only when it is actually placed in the environment has been realized.
[0009]
In the invention described in Japanese Patent Application Laid-Open No. 10-185609, a portable information device detects its own position using a satellite, searches local information from the detected own position, and selectively outputs it. It has been broken.
Further, in the invention described in Japanese Patent Application Laid-Open No. 9-113599, there is an action to be performed at the location when the current location of the user approaches the registered location or leaves the registered location. Is notified to the user.
[0010]
In the invention described in Japanese Patent Application Laid-Open No. 11-15876, a history of processing performed when the user is in a place that can be represented by position information is saved, and a history that matches the current position information is referred to. Then, the contents of the process corresponding to the position information are output, or the process performed at a place close to the current position information is selected from the history and the contents are output.
[0011]
[Problems to be solved by the invention]
However, when a terminal device capable of registering or searching for information only at a specific position is used, for example, if there is an error in the position information acquired by the terminal device, the position is set as described above. There is a problem in that it is impossible to share information corresponding to the position only with the user who has actually placed it and to perform registration or search of the information, and for example, such a position If there is an error in the information, there arises a problem that a security problem may occur with respect to the information corresponding to the position. For this reason, when the terminal device is used by the user, it is necessary to confirm whether or not the terminal device really exists at a position corresponding to the position information acquired by the terminal device.
[0012]
Here, as a case where an error occurs in the position information acquired by the terminal device, for example, a case where a malfunction occurs in the terminal device can be considered, for example, position information where an unauthorized user is acquired by the terminal device. It may be possible to tamper. That is, since the position information can usually be expressed by simple numerical values such as latitude and longitude, for example, a user who does not actually exist at a certain position falsifies the position information acquired by the terminal device. It can be considered that information corresponding to the position is registered or searched (so-called impersonation) as if it exists in the position, and it is very important to eliminate such an unauthorized user.
[0013]
The present invention has been made in view of such a conventional situation, and can authenticate the validity of the information on the position acquired by the terminal device. It is an object of the present invention to provide a location authentication system, a terminal device, a location management device, and the like that can enable registration and search of information corresponding to the location only by a user who performs the above procedure.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, in the location authentication system according to the present invention, location information acquired by the terminal device is authenticated by the location management device as follows.
That is, in the terminal device, the position information acquisition unit acquires the position information, and transmits the position information acquired by the position information transmission unit to the position management device.
On the other hand, in the location management device, the terminal location information holding unit holds information on the location of the terminal device from which location information can be received by the location information receiving unit, and the location information receiving unit is transmitted from the terminal device. The location corresponding to the location information received by the location information receiving means can be received by the location information receiving means based on the content held by the terminal location information holding means. If the received location information is included in the existing location of the terminal device, it is authenticated that the received location information is valid, and the authentication result information transmission means transmits the authentication result information of the authentication means to the terminal device.
In the terminal device, the authentication result information receiving means receives the authentication result information transmitted from the position management device, and the acquired position information is valid based on the authentication result information received by the processing means. If confirmed, the process is executed using the position information.
[0015]
Therefore, the location information acquired by the terminal device can be authenticated by the location management device, and this makes it possible to execute processing using the location information only by the terminal device that really exists at a certain location. can do.
[0016]
Here, various information may be used as the position information. For example, latitude and longitude information may be used.
Various position information acquisition means may be used. As a preferred mode, for example, a receiver of a global positioning system (GPS) can be used.
Further, information communication between the terminal device and the position management device may be performed using a wireless line, for example, or may be performed using a wired line, for example.
[0017]
In addition, as information on the location of the terminal device that can receive the location information by the location information receiving unit of the location management device, the location information receiving unit from the terminal device if the terminal device exists at any location. Information that specifies whether position information can be received is used. Specifically, as such information, for example, when wireless communication is performed between the terminal device and the position information receiving unit of the position management device, the terminal capable of wireless communication by the position information receiving unit Information on the position of the device is used. For example, when wired communication is performed between the terminal device and the position information receiving unit of the position management device, a wired line (cable for communication by the position information receiving unit) ) And the position information where the connector for connecting the terminal device is installed is used.
[0018]
Note that, for example, a position range having a width may be used as the presence position of the terminal device capable of receiving the position information by the position information receiving unit of the position management device. For example, the position range has no width. A single point location may be used. Specifically, for example, when wireless communication is performed between the terminal device and the position information receiving unit of the position management device, the position where wireless communication can be performed by the position information receiving unit has a width ( For example, when wired communication is performed between the terminal device and the position information receiving means of the position management device, if the above-described connector is fixedly installed, the installation position is a single position. It becomes.
[0019]
Further, as a case where the position corresponding to the position information received by the position information receiving unit of the position management device is included in the presence position of the terminal device capable of receiving the position information by the position information receiving unit, for example, the terminal device When the wireless communication is performed between the terminal information and the position information receiving means, the case where the terminal device exists at a position where the wireless communication can be performed by the position information receiving means is applicable. When wired communication is performed with the position information receiving means of the position management device, a connector for connecting a wired line (cable) and a terminal device for wired communication by the position information receiving means is installed. This corresponds to the case where a terminal device exists at the position.
[0020]
Further, as the authentication result information transmitting means of the position management apparatus, for example, a means for transmitting the authentication result information to the terminal apparatus only when the position information is authenticated is used. For example, even when it is determined that the position information is invalid, a means for transmitting the authentication result information to the terminal device may be used.
[0021]
Various processes may be used as the process executed by the processing unit of the terminal device. For example, a process of registering information in association with position information, a process of searching for information corresponding to the position information, A process for releasing (decrypting) encrypted information corresponding to the position information, a process for receiving (downloading) information corresponding to the position information from another device via a network, or the like can be used.
[0022]
Further, in the terminal device, it is necessary to confirm that the positional information acquired when executing the processing by the processing means is valid. For example, such a confirmation is not possible for a certain predetermined processing. It is also possible to use a configuration that can be executed without it, while other predetermined processes cannot be executed without such confirmation. In such a configuration, processing that cannot be executed unless the positional information is confirmed to be valid corresponds to processing executed by the processing means of the terminal device according to the present invention.
[0023]
In the location authentication system according to the present invention, the location information acquired by the terminal device is authenticated based on the information received from the location management device as follows.
That is, in the location management device, the terminal location information transmission unit transmits information on the location of the terminal device to which information can be transmitted by the unit to the terminal device.
On the other hand, in the terminal device, the position information acquisition unit acquires the position information, the terminal position information reception unit receives the terminal position information transmitted from the position management device, and the position corresponding to the position information acquired by the authentication unit is When the received location information is included in the location of the terminal device corresponding to the received location information, the obtained location information is authenticated, and the processing means acquires the location information based on the authentication result of the authentication means. When it is confirmed that is valid, the process is executed using the position information.
[0024]
Accordingly, the location information acquired by the terminal device can be authenticated by the terminal device based on the terminal location information received from the location management device, and thus the location information can be obtained only by the terminal device that really exists at a certain location. It is possible to execute processing using the information.
[0025]
Here, as the information on the location of the terminal device capable of transmitting information by the terminal location information transmitting means of the location management device, as in the above, if the terminal device is in any location, the terminal location information Information that specifies whether information can be transmitted to the terminal device by the transmission means is used. Similarly to the above, specifically, as such information, for example, when wireless communication is performed between the terminal device and the terminal location information transmission unit of the location management device, the terminal location information transmission unit Information on the location of a terminal device capable of wireless communication is used, and when, for example, wired communication is performed between the terminal device and terminal location information transmission means of the location management device, the terminal location information is transmitted. Information on a position where a connector for connecting a wired line (cable) for wired communication by means and a terminal device is installed is used.
[0026]
In the location authentication system according to the present invention, the location information acquired by the terminal device is authenticated based on the information received from the location management device as follows.
That is, in the location management device, the identification information transmitting means transmits the identification information to the terminal device.
On the other hand, in the terminal device, the terminal location information holding unit holds information on the location of the terminal device that can receive the identification information transmitted from the identification information transmission unit of the location management device, and the location information acquisition unit Acquires the position information, the identification information receiving means receives the identification information transmitted from the identification information transmitting means of the position management device, and the authentication means acquires the position information acquired based on the content held by the terminal position information holding means. If the position corresponding to the ID is included in the presence position of the terminal device capable of receiving the received identification information, the acquired position information is authenticated and the processing means authenticates the authentication result. When it is confirmed that the acquired position information is valid based on the above, the process is executed using the position information.
[0027]
Accordingly, the position information acquired by the terminal device can be authenticated by the terminal device based on the identification information received from the position management device, and thus the position information can be obtained only by the terminal device that really exists at a certain position. It is possible to perform processing using information.
[0028]
Here, as the identification information, for example, information for identifying the identification information transmission means provided in the position management apparatus is used. When the position management apparatus is provided with a plurality of identification information transmission means, for example, each identification information transmission means Different identification information is used for each. In addition, when the location management device is provided with only one identification information transmission unit, information for identifying the location management device can be used as the identification information.
[0029]
Further, as the information on the location of the terminal device capable of receiving the identification information transmitted from the identification information transmitting means of the location management device, the terminal device can be located at any location as described above. Thus, information for specifying whether or not the identification information from the identification information transmitting means can be received is used. Further, as described above, specifically, as such information, for example, when wireless communication is performed between the terminal device and the identification information transmission unit of the location management device, the information with the identification information transmission unit Information on the position of the terminal device capable of wireless communication between the terminal device and the identification information transmitting unit when, for example, wired communication is performed between the terminal device and the identification information transmitting unit of the position management device.

[0034]
In addition, an effective combination of satellite identifier information and time information is determined according to the use status of GPS. Specifically, for example, information can be received at a certain time by a terminal device located at a certain position. Since such satellites are limited, such time information and such satellite identifier information are effective combinations. In the present invention, for example, the location information of the terminal device can be transmitted from the terminal device to the location management device and used for authentication. However, the location of the terminal device is determined by the terminal device. Since the effective combination of satellite identifier information and time information does not change even if the position changes in a relatively wide range, the position of the terminal device is taken into consideration. At least, it is possible to authenticate the position information acquired by the terminal device based on the satellite identifier information and the time information.

Based on the authentication result information received from the management device and received by the processing means, when it is confirmed that the information regarding the acquired position is valid, the process is executed using the acquired position information.
[0037]
Here, as the information regarding the position acquired by the terminal device, as described above, for example, the position information acquired by the position information acquisition unit, the satellite identifier information used for calculating the position by GPS, and the time, for example, Information etc. can be used.
[0038]
Moreover, in the terminal device which concerns on this invention, a process is performed using the acquired positional information as follows.

The process is executed using the position information.
[0039]
Here, as information used as a reference when authenticating the information regarding the position acquired by the terminal device, as described above, for example, information is communicated with the communication means provided in the position management device. Can be used, for example, information on the location of a terminal device that can be used, identification information of a communication means provided in the position management device, information on an effective combination of satellite identifier information and time information related to GPS, and the like.
[0040]
As another example, position information acquired by position information acquisition means provided on a vehicle such as a bus on which a user carrying the terminal device is riding can be used as reference information. For example, in the vehicle, position information acquired by the vehicle is transmitted to the terminal device accommodated in the vehicle, and the terminal device acquires position information of the terminal device based on the position information received from the vehicle. The position information acquired by the means is authenticated.
[0041]
Similarly, as another example, information on the position of the base station apparatus transmitted from the base station apparatus can be used as reference information. In this case, for example, the base station apparatus has a communication range within the communicable position range. The location information of the base station device is transmitted to the accommodated terminal device, and the location information acquired by the location information acquisition unit of the terminal device is obtained based on the location information received from the base station device.

[0042]
Further, the present invention provides a position management device provided in the position authentication system as described above.
Specifically, the position management device according to the present invention authenticates information regarding the position acquired by the terminal device as follows.

Further, for example, when the position corresponding to the position information acquired by the GPS receiver of the terminal device is included in the communicable position range of the base station device that performs wireless communication with the terminal device, the position information is valid. In the authentication method for authenticating that the location information is authentic, the position information acquired by the GPS receiver is relatively accurate with respect to the relatively wide communicable location range of the base station device, and the GPS reception It is possible to take advantage of both the advantage that the position information acquired by the machine is relatively easy to be tampered with and the information about the communicable position range of the base station apparatus is relatively difficult to be tampered with.
[0050]
In addition, in the present invention, for example, a mode in which the position information acquired by the terminal device is authenticated every time processing is executed by the processing unit of the terminal device can be used. It is also possible to use a mode that authenticates location information acquired by the terminal device only in such a case. In such a mode, compared to a case where authentication is performed every time processing is performed by the processing unit of the terminal device.

[0056]
Next, an example of an information registration device and an information search device is shown as a preferable device example to which the position authentication system, the terminal device, and the position management device according to the present invention can be applied.
In the information registration device, for example, registration information input by a user and information on one or a plurality of environments at the time of input are registered in association with each other and held by a storage unit.
Specifically, the information registration apparatus includes input means such as an input pad, a camera, and a microphone for the user to input fragmentary registration information such as a memo, a photograph, and a voice comment, and the position, altitude at the time of registration. Environment information acquisition means such as a global positioning system (GPS), an altimeter, a speedometer, a thermometer, a hygrometer, a clock, etc., for acquiring information on the environment outside the device such as speed, temperature, humidity and time.
[0057]
As an example, longitude, latitude, altitude, speed provided from GPS, date provided from a clock, time, temperature provided from a thermometer, humidity provided from a hygrometer, and the like are used as environmental information. For example, but not limited to, air pressure, air volume / direction, sound intensity / frequency, light intensity / ultraviolet radiation / infrared radiation, radiation dose, and other chemical analysis methods and scientific analysis methods It is also possible to use a numerical value to be used as environmental information.
[0058]
Here, as a method of associating the registration information with the environment information, for example, a method of associating one-to-one, for example, (a part of or all of) environment information having a range (environment attribute) and registration information Or a method of associating identification information (representative value) of such an environmental attribute (environment range) with registered information, for example. In addition, in the information registration device, for example, not only a configuration that allows registration only when in the environment, but also registration information and environment information can be associated and registered anytime and anywhere (at any time or any place). It can also be configured.
[0059]
Note that if the environment range at the time of registration is set smaller than the environment range required at the time of search (search environment range), for example, even if there is a slight error in the value of the environment information It is possible to search for registered information that matches the actual environment, and for example, even when the user environment (the environment at the time of search) changes, it is smooth according to changes in the environment. It is possible to realize that information search is performed, and for example, it is possible to easily and quickly perform registration information search processing.
[0060]
As an example, the size of the minimum environmental range (at the time of registration) is preferably set to about the accuracy of the value of the environmental information acquired by the environmental information acquisition means. For example, a GPS that does not perform current correction processing Is about 10 m (0.3 seconds to 0.4 seconds) (for latitude and longitude in the vicinity of Japan), so when this system is used (for latitude and longitude in the vicinity of Japan), 3 m (0. It is preferable to use a position range of about 1 second) as the minimum position range. Here, “second” indicates the second of “xxx degrees ΔΔ minutes OO. ○ seconds”.
[0061]
In the information search apparatus, for example, when there is a search instruction input (for example, input of a search start command, input of a search key (keyword), input of a search range, power-on, etc.) The registered information corresponding to the environmental information is searched based on the information, and the search result is presented.
Here, as a presentation method, for example, a method of displaying and outputting information on a screen, a method of printing and outputting information by a printer, a method of outputting information from a speaker, and the like can be used.
[0062]
Further, as environment information for search, for example, information (environmental conditions) obtained by adding a range to (partial or all) environment information can be used. In this case, the size of the search environment range can be designated by the user, for example, or can be set in advance, for example. In this case, the searched information can be presented for each environment range included in the search environment range.
[0063]
As described above, in the information registration device and the information search device, for example, environment information and registration information are associated with each other on a one-to-one basis, and registration information is searched using environment information as a key. To search for registration information using environment information as a key, for example, to search for registration information using environment conditions as a key by associating environment information and registration information, It is possible to search registration information by associating registration information with environmental conditions as a key.
Further, for example, the information registration device and the information search device can be integrated to constitute an information registration search device.
[0064]
Further, for example, an information registration device and an information search device can be configured by separately providing a terminal device that can be carried by a user and a management device that manages registration information. In such a configuration, the terminal device acquires the environment information and associates the acquired environment information with the registration information and transmits the information to the management device for registration, or transmits the acquired environment information to the management device. The registration information corresponding to the environmental information returned from the management apparatus is received and presented. Further, the terminal device and the management device communicate with each other wirelessly (may be wired).
[0065]
In addition, for example, registration information corresponding to various environments can be collectively managed by one management apparatus, or (another) management apparatus that stores registration information corresponding to the position is installed for each position, for example. You can also.
[0066]
In addition, as a method of searching for information, for example, a configuration in which information is searched (selected) on the management device side can be configured. For example, a configuration in which information is searched on the terminal device side can also be configured. For example, it is possible to search for information within a certain range on the management device side, and further search for information from the certain range of information on the terminal device side.
[0067]
Further, for example, a management device can be configured from a management unit that manages registration information and one or more wireless communication units (such as a wireless base station device) that perform wireless communication. As an example, the management unit and the wireless communication unit are installed apart from each other, the wireless communication unit wirelessly communicates information with the terminal device, and the management unit is wired between the wireless communication unit and the information. Or it communicates by radio.
[0068]
Further, in the terminal device, for example, the main body and the position information acquisition means (for example, GPS) portion can be configured as detachable separate bodies, or the position information acquisition means portion is built in the main body (the terminal device). It can also be. When GPS is used, it is preferable to place a GPS receiver above the user's head and shoulders because GPS signals from satellites are easily received by the GPS receiver.
[0069]
Further, as a method of acquiring position information, for example, in addition to the method using the GPS device as described above, for example, wireless transmission is performed from a base station device such as PHS (Personal Handy phone System) (for example, the base There is also a method of receiving position information (of the station apparatus) and acquiring the position information. As described above, the present invention includes a configuration for authenticating the position information acquired by the terminal apparatus using the position information of such a base station apparatus.
[0070]

[0073]
FIG. 2 shows a configuration example of the base station apparatuses B1 to BN of the present example and the server apparatus S of the present example. In this example, N (N is a plurality) base station apparatuses B1 to BN are connected to the server apparatus S via a network P such as the Internet. In addition, since the configurations of these N base station apparatuses B1 to BN are the same, the specific configuration example of only one base station apparatus B1 is shown in FIG.
[0074]
As shown in the figure, the base station apparatus B1 of the present example wirelessly communicates between a base station identifier information holding unit 11 that holds identifier information unique to the base station apparatus B1 and a mobile terminal apparatus T. It is comprised from the communication part 12 which communicates information and communicates information with the server apparatus S via the network P (base station). As described above, the other base station apparatuses B2 to BN have the same configuration.
[0075]
Here, each base station apparatus B1 to BN is arranged in a necessary number according to the usage status of the system so as to cover a predetermined area as a communicable position range. Different base station identifier information is set in each BN. In addition, as a communicable position range of each base station apparatus B1-BN, for example, you may have a position range which overlaps between base station apparatuses, or even if it does not have such an overlapping position range. Good.
[0076]
Further, as shown in the figure, the server device S of this example communicates information between the base station devices B1 to BN via the network P (server) communication unit 21 and the mobile terminal device T. (Server) information unit group holding unit 22 that holds registration information to be provided to the base station, base station identifier information of each base station device B1 to BN, and the area (communication possible position) covered by each base station device B1 to BN A base station position information holding unit 23 that holds a correspondence relationship with a range), a payment information holding unit 24 that manages a payment status for each user (user) or registration information of the mobile terminal device T, and a GPS satellite A raw data determination reference information holding unit 25 that stores a valid combination of satellite identifier information and time information received, and an information unit transmission determination unit 26 that determines whether or not registration information is distributed to the mobile terminal device T. And composed of It has been.
[0077]
Next, as a first example, a specific example of a process of distributing information from the server device S to the mobile terminal device T and presenting the information by the mobile terminal device T will be described.
More specifically, in this example, the user of the mobile terminal device T requests the presentation of registration information corresponding to the location of the mobile terminal device T, and payment of the fee for the registration information has been completed. Only when the existence of the mobile terminal device T at the position is authenticated and the validity of the location is guaranteed, the information is distributed from the server device S and presented by the mobile terminal device T.
[0078]
FIG. 3 shows an example of the procedure of such processing.
That is, first, the user of the mobile terminal device T operates the mobile terminal device T to instruct to present an overview of what information is associated with the current position of the mobile terminal device T. (Step S1).
Then, in the mobile terminal device T, the position information acquisition unit 1 acquires the position where the mobile terminal device T currently exists using a device such as GPS (step S2).
[0079]
Next, in the mobile terminal device T, the position validity determination unit 5 stores information cached in the information unit group holding unit 2 in advance based on the position information calculated and acquired by the position information acquisition unit 1. Search is performed (step S3), the registration information assigned to the position is extracted, and the overview is presented by the information presentation unit 6 (step S4).
In the search, for example, registration information corresponding to a position where the current position of the mobile terminal device T is exactly the same as the latitude and longitude may be extracted, or, for example, a certain range may be determined and the mobile terminal Registration information corresponding to a position within the range centered on the current position of the device T may be extracted.
[0080]
Here, FIG. 4 shows an example of information units held in the information unit group holding unit 2 of the mobile terminal apparatus T. As shown in the figure, each information unit includes an ID section 31 for storing identification information (ID number in this example) of each information unit, a name section 32 for storing the name of each information unit, and each information unit. Content section 33 for storing the contents of the text information of the unit and the position information (latitude and longitude in this example) associated with each information unit, the keyword assigned to each information unit, and the information related to each information unit And a keyword part 34 for storing a file identifier of image information.
[0081]
In this example, description will be made on the assumption that the information of the title “Flat stag beetle” corresponding to the ID number = 07482 shown in FIG.
In this case, as described above, the information presentation unit 6 of the mobile terminal device T presents the user with an overview of the extracted information instead of all of the extracted information. Only text information included in the information is presented to the user as an overview.
[0082]
Here, FIG. 5 shows an example of an overview of information units presented by the information presentation unit 6. As shown in the figure, for example, on the screen of the mobile terminal device T, a name area 41 for displaying the name of the information unit, a content area 42 for displaying the contents of the text information and the position information of the information unit, An image area 43 that displays image information in information units, a keyword area 44 that displays information on keywords assigned to information units, and a search result display area 45 that displays the names of searched information units as search results are provided. It is done.
[0083]
In the example screen shown in FIG. 6, the names of a plurality of searched information units are displayed in the search result display area 45, and the names of the information units selected from the plurality of information units are displayed in the name area 41. The contents of the text information and the position information of the information unit are displayed in the content area 42, and the keyword information assigned to the information unit is displayed in the keyword area 44. In addition, in the screen example of the figure, an information unit search button 51 for instructing the search of the information unit is displayed, and in order to instruct to acquire more detailed information regarding the information unit for which the overview is presented. The information acquisition button 52 is displayed in the image area 43.
[0084]
By displaying such an information acquisition button 52, the user can grasp that more detailed information is present on the server device S with respect to the information unit for which the overview is presented. In this case, the user can By pressing the information acquisition button 52, it is possible to instruct the mobile terminal device T to acquire more detailed information (step S5).
[0085]
When the information acquisition button 52 described above is pressed, in the mobile terminal device T, the position validity determination unit 5 sends an acquisition command for requesting the server device S to transmit detailed information through the communication unit 4. For example, it is transmitted wirelessly to the base station device B1 that can communicate with the communication unit 4 (step S6).
[0086]
Here, FIG. 6 shows an example of an acquisition command transmitted from the mobile terminal device T to the server device S. As shown in the figure, in this acquisition command, the latitude and longitude information acquired by the mobile terminal device T, the information indicating the contents of the command, the information of the file identifier of the information requesting acquisition, Information indicating whether or not each of location authentication, path authentication and purchase authentication is necessary, base station identifier information indicating the communication path of the acquisition command, and authentication status information are stored.
[0087]
Specifically, in the acquisition command shown in the figure, the latitude is “N-35-42-56-9”, the longitude is “E-139-44-03-0”, and the content of the command is This is a request for “acquisition” of information, the information requesting acquisition is image information of a file identifier “hirata_kuwata_234303.jpg”, and location authentication, path authentication, and purchase authentication are all required (“required”). The station identifier information is not stored, indicating that the authentication state is before processing.
[0088]
Next, in the base station apparatus B1, the communication unit 12 receives an acquisition command from the mobile terminal apparatus T by wireless communication, and adds the base station identifier information held in the base station identifier information holding unit 11 to the received acquisition command. Then, the acquired acquisition command is sent to the server device S through the network P (step S7).
[0089]
Here, FIG. 7 shows an example of an acquisition command to which base station identifier information is added. In the acquisition command shown in the figure, the base station identifier information “02361” of the base station apparatus B1 that has received the acquisition command is added to the base station identifier field of the acquisition command shown in FIG. The state is shown as being processed.
[0090]
Next, in the server device S, the communication unit 21 receives the acquisition command from the base station device B1, and the information unit transmission determination unit 26 refers to the registration information stored in the information unit group holding unit 22, and It is determined whether or not the acquisition command is a request from a valid terminal position (step S8).
[0091]
Here, FIG. 8 shows an example of registration information stored in the information unit group holding unit 22 of the server device S. As shown in the figure, each registration information is associated with file identifier information, latitude information, longitude information, and price information, and image information corresponding to the file identifier. Is held in the information unit group holding unit 22.
[0092]
In the above-described position authentication process (step S8), the combination of the position information including the latitude and longitude included in the registration information and the file identifier, the position information including the latitude and longitude included in the acquisition command, and the file identifier By determining whether or not the combination matches, it is determined that the combination is correct if they match, while it is determined that the combination is incorrect if they do not match.
[0093]
For example, as a result of the above-described location authentication (step S8), if the combination of the location and the file identifier is invalid, the server device S indicates that it is an unauthorized access to the requesting mobile terminal device T. By transmitting the rejection information shown, the rejection information is presented to the information presentation unit 6 of the mobile terminal device T (step S16), and the processing according to this example is terminated.
Here, FIG. 9 shows an example of the rejection information presented by the information presentation unit 6 of the mobile terminal device T, and it is indicated in the rejection information window 61 that it is “information that cannot be acquired at the current position”. It is displayed as rejection information.
[0094]
On the other hand, if the result of the above-described position authentication (step S8) indicates that the combination of the position and the file identifier is valid, then in the server device S, the information unit transmission determination unit 26 next checks the validity of the communication path. The route authentication process to be determined is performed (step S9). Specifically, in this path authentication process, the base station identifier information is extracted from the acquisition command shown in FIG. 7 received from the base station apparatus B1, and the extracted base station identifier information and the position information included in the acquisition command are And the combination of the base station identifier and the effective range indicated by the table of the base station radio wave effective range information stored in the base station position information holding unit 23, and requested by the mobile terminal apparatus T. It is determined whether or not the position corresponding to the received information is within the effective range where the radio wave of the base station apparatus corresponding to the base station identifier included in the acquisition command can reach.
[0095]
Here, FIG. 10 shows an example of base station radio wave effective range information held in the base station position information holding unit 23 of the server apparatus S. As shown in the figure, in the base station radio wave effective range information table, the base station identifier information of each base station apparatus B1 to BN and the latitude at which each base station apparatus B1 to BN can communicate wirelessly Is associated with information on the effective range relating to longitude at which each base station apparatus B1 to BN can perform wireless communication.
[0096]
In the above-described route authentication process (step S9), with reference to such base station radio wave effective range information, the latitude and longitude included in the acquisition command from the mobile terminal device T are the base station identifiers included in the acquisition command. The combination of the latitude and longitude included in the acquisition command and the base station identifier is valid by determining whether or not it is included in the effective range of latitude and longitude that can be wirelessly communicated by the base station device corresponding to It is determined whether or not.
[0097]
For example, as a result of the above-described path authentication (step S9), the base station identifier included in the acquisition command from the mobile terminal apparatus T is not originally transmitted to the position included in the acquisition command (for example, the base station apparatus In the server apparatus S, when the information unit transmission determination unit 26 indicates that the information has been transmitted to the server apparatus S via the station apparatuses B2 to BN), for example, rejection information similar to that shown in FIG. Is used to indicate to the information presenting unit 6 of the mobile terminal device T that the unauthorized access is made (step S16), and the processing according to this example is terminated.
[0098]
On the other hand, if the result of the above-described path authentication (step S9) and the combination of the latitude and longitude included in the acquisition command and the base station identifier are valid, the server device S then sends information units. The determination unit 26 refers to the registration information shown in FIG. 8 held in the information unit group holding unit 22 to determine whether the information requested by the acquisition command is charged (step S10). ).
[0099]
If the information requested by the acquisition command is pay information as a result of this determination, in the server device S, the information unit transmission determining unit 26 executes the following charging process, and the information is sent to the user. Authenticate that it is purchased by
That is, in this billing process, first, a payment request is presented to the information presentation unit 6 of the mobile terminal device T (step S11).
Here, FIG. 11 shows an example of a payment request presented by the information presentation unit 6 of the mobile terminal device T, and a charge (“charge 30 yen”) is displayed in the payment request window 71. In addition, a purchase button 72 and a cancel button 73 are displayed.
[0100]
Next, in this billing process, it is determined whether or not the user of the mobile terminal apparatus T has confirmed payment (step S12). For example, if the user does not accept payment by pressing the cancel button 73, the mobile terminal apparatus The T information presentation unit 6 presents an inaccessible notification indicating that the user cannot be accessed (step S17), and the processing according to this example is terminated.
Here, FIG. 12 shows an example of the inaccessible notification presented by the information presenting unit 6 of the mobile terminal device T. In the inaccessible notification window 81, “Waiting for another use” Is displayed as an inaccessible notification.
[0101]
On the other hand, in the above-described payment confirmation, when the user presses the purchase button 72 to accept payment, information related to purchase (mobile terminal device T based on the payment information for each user held in the payment information holding unit 24). (Information requested by an acquisition command from) is performed, and a charge for the information is settled.
[0102]
Here, FIG. 13 shows an example of payment information for managing the payment status for each user as the payment information held in the payment information holding unit 24 of the server device S. As shown in the figure, in this payment information, the information of the identifier of each user who uses each mobile terminal device T, the payment method of electronic charges such as electronic money, and the information of the identification number (No.) related thereto, The information on the usage limit, the information on the used amount, and the information on the available amount (= use limit amount−used amount) are associated with each other. When information is purchased by a certain user, the price of the information is added to the used amount, and the price is subtracted from the available amount.
[0103]
FIG. 14 shows an example of payment information for managing the payment status for each registered information as another example of the payment information held in the payment information holding unit 24 of the server device S. As shown in the figure, in this payment information, the file identifier information of each registration information is associated with the identifier of the user who paid the fee for each registration information. Here, when such payment information is used, it is possible to determine which user has paid the fee for each piece of registration information.
For example, when it is possible to confirm that the payment of the fee for the information requested by the acquisition command has already been completed by the user of the mobile terminal apparatus T that has transmitted the acquisition command, the charging process (steps described above) By omitting S11, step S12, and step S17), it is possible to start an information presentation process as shown below.
[0104]
Next, when the purchase authentication is performed by the charging process as described above, in the server device S, the information unit transmission determination unit 26 requests from the registration information stored in the information unit group holding unit 22 by an acquisition command. The acquired image information is acquired (step S13), and the acquired image information is transmitted to the requesting mobile terminal device T through the communication unit 21 (step S14). The transmitted image information is relayed by the communication unit 12 of the base station device B1 via the network P, and is wirelessly transmitted from the communication unit 12 to the requesting mobile terminal device T.
[0105]
Next, in the requesting mobile terminal device T, all the conditions necessary for the communication unit 4 to wirelessly receive the image information from the base station device B1 and for the position validity determination unit 8 to present the image information are as follows. After finally confirming that it has been cleared, the image information is presented by the information presentation unit 6 (step S15), and the processing according to this example is terminated.
[0106]
Here, FIG. 15 shows an example of an information unit including image information presented by the information presentation unit 6 of the mobile terminal device T. The display content (information unit) similar to that shown in FIG. In addition to the search result, the name of the specific information unit, the content of the text, and the keyword thereof, the image information of the information unit is displayed in the image area 43. Further, in the example screen shown in the figure, an information unit registration button 53 for registering an information unit is also displayed.
[0107]
In the above-described processing according to this example, the configuration in which the mobile terminal device T and the base station devices B1 to BN communicate wirelessly is used. For example, the mobile terminal device is connected to a wired network. It is also possible to use a configuration in which the mobile terminal device and the base station device are communicably connected via the network. Specifically, in such a configuration using wired communication, for example, a connector terminal for connecting a mobile terminal device to a wired network is provided, and the relationship between the identifier of the connector terminal and the installation position of the connector terminal Is stored in the server device (a storage unit similar to the base station location information holding unit 23 provided in the server device), and the validity of the location acquired by the terminal device T is determined based on the relationship.
[0108]
Next, as a second embodiment, when the information held in the information unit group holding unit 2 of the mobile terminal device T is encrypted, the mobile terminal device T decrypts the information and releases the information. A specific example of the process of presenting
More specifically, in this example, the user of the mobile terminal device T requests the presentation of registration information corresponding to the location of the mobile terminal device T, and payment of the fee for the registration information has been completed. Only when it is authenticated that the mobile terminal apparatus T exists at the position and the validity of the position is guaranteed, the mobile terminal apparatus T releases the encryption of the registered information and presents the information.
[0109]
FIG. 16 shows an example of the procedure of such processing. In this example, a process similar to the process described with reference to FIG. 3 of the first embodiment will be briefly described.
That is, first, the user of the mobile terminal device T operates the mobile terminal device T to give an instruction to present an overview of what information is available corresponding to the current position of the mobile terminal device T. (Step S21).
[0110]
Then, in the mobile terminal apparatus T, the position information acquisition unit 1 acquires the position where the mobile terminal apparatus T currently exists using a device such as GPS (step S22), and based on the acquired position, The validity determination unit 5 searches for information cached in the information unit group holding unit 2 in the form shown in FIG. 4 in advance (step S23), and extracts registration information assigned to the position. Then, the information presentation unit 6 presents an overview of the information (step S24).
[0111]
Here, in this example, as in the case of the first embodiment, it is assumed that the information of the title “Hirata stag beetle” corresponding to ID = 0482 shown in FIG. 4 is retrieved and extracted, for example. I do.
[0112]
Next, when the information acquisition button 52 is displayed in the overview information as shown in FIG. 5 above, the user of the mobile terminal device T can grasp that this information has detailed information, In response, the information acquisition button 52 is pressed to instruct to acquire detailed information (step S25).
Then, in the mobile terminal device T, the location validity determination unit 5 sends a route authentication request command for requesting route authentication to the server device S through the communication unit 4, for example, a base that can communicate with the communication unit 4. It is transmitted by radio to the station apparatus B1 (step S26).
[0113]
Here, FIG. 17 shows an example of a route authentication request command transmitted from the mobile terminal device T to the server device S. The route authentication request command includes, for example, the acquisition command shown in FIG. Some similar information is stored.
Specifically, in the route authentication request command shown in the figure, the latitude is “N-35-42-56-9”, the longitude is “E-139-44-03-0”, and the command The request is “route authentication”, there is no information (file) to request acquisition, location authentication is not required, route authentication is required (“required”), purchase authentication is not required, and the base station No identifier information is stored, indicating that the authentication state is before processing.
[0114]
Next, in the base station device B1, the communication unit 12 receives the route authentication request command from the mobile terminal device T, and adds the base station identifier information held in the base station identifier information holding unit 11 to the route authentication request command. Then, the added route authentication request command is sent to the server device S through the network P (step S27).
[0115]
Here, FIG. 18 shows an example of a route authentication request command to which base station identifier information is added. In the path authentication request command shown in the figure, base station identifier information “02361” of the base station apparatus B1 that has received the path authentication request command is added to the base station identifier field of the path authentication request command shown in FIG. In addition, it is indicated that the authentication state is being processed.
[0116]
Next, in the server device S, the communication unit 21 receives the route authentication request command from the base station device B1, and the information unit transmission determination unit 26 performs route authentication processing for determining the validity of the communication route (step S28). . In this route authentication process, for example, the same processing as in the first embodiment is performed. Specifically, latitude and longitude information and base station identifier information are extracted from the route authentication request command, and a combination thereof is obtained. And the base identifier stored in the base station location information holding unit 23 in the form as shown in FIG. 10 above and the combination of the latitude and longitude valid ranges, the latitude and It is determined whether or not the position corresponding to the longitude information is within the effective range of latitude and longitude to which the radio wave of the base station apparatus corresponding to the base station identifier information included in the path authentication request command is received.
[0117]
As a result of such route authentication (step S28), for example, information on the base station identifier of the base station device that cannot originally receive radio waves at the position corresponding to the latitude and longitude information included in the route authentication request command If it is included in the path authentication request command, in the server apparatus S, the information unit transmission determining unit 26 rejects the path authentication result notification command indicating unauthorized access through the network P or the base station apparatus B1. Information is transmitted to the requesting mobile terminal device T (step S35).
[0118]
Here, FIG. 19 shows an example of a route authentication result notification command indicating unauthorized access. In this route authentication result notification command, the base station identifier field shown in FIG. The base station identifier information “03013” of the base station apparatus actually used as the communication path is indicated in the communication path identifier field, and the authentication state is indicated as “illegal”. ing.
[0119]
Further, in the mobile terminal device T, when the communication unit 4 receives the route authentication result notification command indicating the unauthorized access as described above, the position validity determination unit 5 displays, for example, the same screen content as shown in FIG. Accordingly, the information presentation unit 6 presents rejection information indicating unauthorized access (step S36), and the processing according to this example is terminated.
[0120]
On the other hand, if the result of the route authentication as described above (step S28) and the combination of the latitude and longitude information and the base station identifier information included in the route authentication request command is a valid combination, the server device S Then, the information unit transmission determining unit 26 sends a route authentication result notification command indicating that the route is authenticated to the mobile terminal device T through the communication unit 21 (step S29).
[0121]
Here, FIG. 20 shows an example of a route authentication result notification command indicating that the route is authenticated. In this route authentication result notification command, the base station identifier shown in FIG. Column is changed to the communication path identifier field, and information “02361” of the base station identifier of the base station apparatus B1 actually used as the communication path is shown in the communication path identifier field, and the authentication state is “valid”. It has been shown that there was.
[0122]
When the path is authenticated as described above, in the server device S, the information unit transmission determination unit 26 is held in the information unit group holding unit 22 as shown in FIG. With reference to such registered information, it is determined whether or not the information requested to be presented by the mobile terminal device T is charged (step S30). A billing process similar to that shown in the first embodiment is performed (step S31, step S32, step S37), and purchase authentication is performed.
[0123]
Specifically, in this billing process, first, the payment request as shown in FIG. 11 is presented by the information presentation unit 6 of the mobile terminal device T (step S31).
Next, in this accounting process, payment confirmation by the user of the mobile terminal device T is determined (step S32). For example, if the user does not accept payment, the information presenting unit 6 of the mobile terminal device T receives the above-described FIG. As shown in (2), the fact that access is not possible is presented (step S37), and the processing according to this example is terminated.
[0124]
On the other hand, in the above payment confirmation, when the user accepts the payment, the user is charged based on the payment information for each user held in the payment information holding unit 24 in the form as shown in FIG. , Pay for information.
As described in the first embodiment, for example, when it is possible to determine that the payment for the information has been completed based on the payment status for each registered information as shown in FIG. It is possible to omit the charging process (step S31, step S32, step S37) as described above and start an information presentation process as shown below.
[0125]
Next, when purchase authentication is performed by the above billing process, the descrambling of the encrypted information is permitted by the server device S. In response to this, the descrambling unit 3 in the mobile terminal device T After decrypting the encrypted image information stored in the holding unit 2 (step S33), the information presenting unit 6 presents the decrypted image information, for example, as shown in FIG. Step S34), the processing according to this example is terminated.
[0126]
Here, FIG. 21 shows an example of the encrypted image information 91 held in the information unit group holding unit 2 of the mobile terminal apparatus T. This image information 91 is stored in the information unit group holding unit 2. It is specified by the file identifier included in the registration information held in. The form of the registration information held in the information unit group holding unit 2 of the mobile terminal device T is the same as the form of the registration information shown in FIG.
[0127]
In this example, an example in which a relatively simple cryptographic processing mechanism is used has been described. However, for example, depending on the importance of security of information presented by the mobile terminal device T, cryptographic processing that is more complicated than this example is performed. It is also possible to use a mechanism.
[0128]
Next, as a third embodiment, a specific example of processing for authenticating whether or not the raw data used for position calculation by the mobile terminal apparatus T is valid will be described.
Here, in the first embodiment and the second embodiment, the legitimacy of the position acquired by the mobile terminal apparatus T based on the installation positions of the base station apparatuses B1 to BN is guaranteed, but in this example, By authenticating the raw data used when calculating such a position, the correctness of the position is guaranteed. In the mobile terminal device T of this example, the position is calculated using a GPS receiver, and satellite identifier information and time information received from a GPS satellite are used as raw data when calculating the position.
[0129]
FIG. 22 shows an example of the procedure of such processing.
That is, first, in the mobile terminal apparatus T, the position information acquisition unit 1 acquires information on the position where the mobile terminal apparatus T currently exists using a GPS receiver (step S41). When a position is acquired by a GPS receiver, it is usually emitted from a specific satellite that can receive radio waves at the position of the GPS receiver among a plurality of GPS satellites that move at high speed around the earth. The received radio wave is received and the position is calculated.
[0130]
The mobile terminal device T receives satellite identifier information and time information transmitted from the satellite as raw data when calculating the position as described above. Next, the position validity determination unit 5 receives the position information. A path authentication request command including information on the position acquired by the acquisition unit 1 and information on the raw data used for calculation of the position is transmitted via the communication unit 4 via, for example, the base station device B1. It transmits with respect to the server apparatus S (step S42).
[0131]
Here, FIG. 23 shows an example of a route authentication request command including raw data information. As shown in the figure, the route authentication request command includes latitude and longitude information acquired by the mobile terminal device T, transmission time and satellite identifier acquired from the GPS satellite by the mobile terminal device T (used satellite). ), Information indicating the contents of the command, information on the file identifier of information requesting acquisition, information indicating whether each of location authentication, path authentication, and purchase authentication is required, and communication Information on the base station identifier indicating the route and information on the authentication state are stored.
[0132]
Specifically, in the path authentication request command shown in the figure, the latitude is “N-35-42-56-9”, the longitude is “E-139-44-03-0”, and from the satellite. The transmission time is “PM 3:43:22 JST (Japan Standard Time)”, the satellite identifiers are “03, 08, 12, 16”, and the command content is “route authentication”. There is no information (file) requesting acquisition, location authentication is not required, route authentication is required (“required”), purchase authentication is not required, and communication path identifier information is stored This indicates that authentication status information is not stored.
[0133]
Next, in the server device S, when the communication unit 21 receives the path authentication request command from the mobile station device T via the base station device B1, the information unit transmission determination unit 26 stores the raw data determination reference information holding unit 25. Time information and satellite identifier information included in the received path authentication request command are compared with the determination standard information by referring to the stored determination criteria information of the raw data, and time information included in the path authentication request command And the validity of satellite identifier information is determined (step S43).
[0134]
Here, FIG. 24 shows an example of the judgment reference information of the raw data held in the raw data judgment reference information holding unit 25 of the server apparatus S. As shown in the figure, in this criterion information, the identifier information “01”, “02”, “03”,... Of each satellite provided in the GPS, and radio waves from each satellite by the mobile terminal device T are shown. Is associated with information on the time (valid time) at which can be received. As a specific example, radio waves from a satellite whose satellite identifier is “01” are received by the mobile terminal device T at “AM 3:22 to AM 5:23” and “PM 3:22 to PM 6:22”. Is possible. Further, in this example, it is assumed that the effective time of GPS satellites in the vicinity of Japan is used, assuming that the mobile terminal device T exists in Japan.
[0135]
The time information and the validity determination processing of the satellite identifier information (step S43) included in the path authentication request command described above specifically corresponds to the time of the time information corresponding to the satellite identifier information in the raw data determination reference information. This is done by determining whether it is included in the attached valid time. If it is included, it is authenticated (step S44), but if it is not included, it is illegal. Is determined (step S45). That is, if the identifier of the satellite that should not be able to receive a radio wave corresponding to the time notified by the route authentication request command from the mobile terminal device T is notified by the route authentication request command, the raw data is invalid. It is determined that there is.
[0136]
When the validity of the raw data is determined as described above, in the server device S, the information unit transmission determining unit 26 sends the determination result to the requesting mobile terminal device T via the base station device B1. Notification, and the processing according to this example is terminated.
[0137]
In general, simple numerical information such as latitude and longitude is easy to falsify, but it is generally difficult to obtain the correspondence between satellite identifier information, which is GPS satellite activation information, and time information. For this reason, in this example, not only a simple position calculation result, but also information of raw data used in such a position calculation process is simultaneously sent from the mobile terminal apparatus T to the server apparatus S for authentication. Thus, it is possible to guarantee the validity of the position information acquired by the mobile terminal device T.
[0138]
As described above, in the information processing system of the present example, as an example, the position acquired by the mobile terminal apparatus T, the installation position of the base station apparatus in which the position for communicating with the mobile terminal apparatus T is determined in advance, and the like If there is no contradiction as a result, it is authenticated that the position information acquired by the mobile terminal device T is valid.
[0139]
Moreover, in the information processing system of this example, as another example, whether the raw data for calculating the position acquired by the mobile terminal apparatus T is compared with the reference information about the raw data, and whether these are consistent or not As a result, if there is no contradiction, the raw data acquired by the mobile terminal apparatus T is valid, and the position information acquired by the mobile terminal apparatus T is valid. Authenticate that.
[0140]
Further, in the information processing system of this example, in the configuration in which the mobile terminal device T is connected to the server device S via the network P, the location information and the raw data acquired by the mobile terminal device T are valid. Only when it is authenticated, the mobile terminal device T is permitted to receive (download) information from the server device S and execute the reception process.
[0141]
Also, in the information processing system of this example, encrypted information is prepared in advance, and only when the location information and raw data acquired by the mobile terminal apparatus T are authenticated as valid. Then, the encryption of the encrypted information is permitted to be released, the descrambling process is performed, and the mobile terminal device T executes the information presentation process.
[0142]
Further, in the information processing system of this example, not only the position information and raw data acquired by the mobile terminal device T are authenticated, but also the movement based on the payment status of the information requested by the mobile terminal device T It is determined whether or not the use of the information by the terminal device T is permitted, and as a result, the fee for the information has already been paid (or the fee for the information can be paid). Only when the use of the information is permitted, the mobile terminal device T executes the information presentation process.
[0143]
In this way, in the information processing system of this example, for example, it is possible to prevent a process that cannot be activated originally from being improperly activated by falsifying position information acquired by the mobile terminal device T. Thus, for example, in a case where information corresponding to the position can be used only by the mobile terminal apparatus T existing at a specific position, the validity of the position information acquired by the mobile terminal apparatus T is valid. Security can be ensured, and information security can be improved.
[0144]
In the above embodiment, the configuration is shown in which the server device S authenticates the location information and raw data acquired by the mobile terminal device T. However, for example, a configuration in which similar authentication processing is performed by the mobile terminal device is used. Is also possible.
Further, as another configuration example, identification information and position information of a base station device are transmitted from the base station device to a mobile terminal device existing in a communicable position range, and the identification received by the mobile terminal device from the base station device It is also possible to use a configuration that authenticates position information acquired by the mobile terminal device based on information or position information.
[0145]

The application field of the present invention is not necessarily limited to the above-described fields, and the present invention can be applied to various fields.
[0146]
In addition, as various types of processing performed in the position authentication system, the terminal device, and the position management device according to the present invention, for example, the processor executes a control program stored in the ROM in a hardware resource including a processor and a memory. May be used, and for example, each functional unit for executing the processing may be configured as an independent hardware circuit.
Further, the present invention can also be grasped as a computer-readable recording medium (storage medium) such as a floppy disk or a CD-ROM storing the control program, or the program (itself).
