  By the way, the terminal holder verifies the location certification information of the terminal held by the terminal holder, and whether or not the terminal holder has existed at a location within a specific range for a specific period (including whether or not it exists) ) There is a desire to provide services appropriately. In this case, it is desirable to more accurately verify whether or not the location certification information has existed for a specific period of time within a specific range.

  However, in Patent Document 1, it is possible to verify when and where a terminal user such as a PDA is present by downloading a location certificate from a server, for example, by a third party service provider. A method for specifically and accurately verifying the location certificate is not disclosed. In addition, since Patent Document 2 plots position information on a map or draws and displays a line connected in time series, it can only verify a visual route, and the terminal holder is within a specific range. It is not possible to verify whether a place has existed for a certain period of time.

  Further, Patent Document 3 discloses only a method for verifying a time stamp or electronic signature of a location certificate using a PKI (Public Key Infrastructure) technique, so that the terminal owner is within a specific range. It is not possible to verify whether a place has existed for a certain period of time. As described above, all of the technologies disclosed in Patent Documents 1 to 3 have a problem that it is impossible to accurately verify whether or not the terminal holder has existed at a place within a specific range for a specific period.

  The present invention has been made in view of this point, and whether or not the terminal has existed in a specific range for a specific period of time is determined by using the position information of the terminal and the time information at the time of acquiring the position information. It is an object of the present invention to provide a location time information verification server, a location certification information verification system, and a location time information verification method that perform accurate verification using the location time information of a terminal including the location time information.

  The location time information verification server according to the present invention includes: an acquisition unit that acquires a plurality of location information of a predetermined mobile terminal transmitted from a communication partner device; and time information indicating a time at which the location information is obtained; Using the acquired location information and time information, verification means for verifying whether or not the mobile terminal exists within a specific range and a specific period, and verification contents by the verification means, the mobile terminal and the mobile A verification result generation unit that generates a verification result that is transmitted to and disclosed at least one of the communication partners other than the terminal, and the verification unit includes a plurality of positions indicated by a plurality of the position information within the specific range. A plurality of times indicated by a plurality of pieces of time information corresponding to a plurality of pieces of position information verified by the position verification and the plurality of pieces of position information verified by the position verification exist within the specific period. It takes the individual to perform configuration and determining time verify whether or not Luke.

  As described above, according to the present invention, whether or not the terminal has existed in a specific range for a specific period includes the terminal position information and the time information at the time of acquiring the position information. It is possible to verify accurately using the location time information of the terminal.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an overall view of a location certification information verification system 100 having a location time information verification server (hereinafter referred to as “verification server”) 300 according to an embodiment of the present invention.

  The location certification information verification system 100 includes a terminal (mobile terminal) 200 owned by a verification target person who requests verification of location certification information indicating the location and the time when the location was acquired, and location certification information transmitted from the terminal. A verification server 300 that verifies (location certificate) and a service providing apparatus 400 that provides a service to the terminal 200 based on a result verified by the verification server 300.

  In this location certification information verification system 100, based on the verification request contents including the location certification information of the terminal 200 held by the person to be verified, the verification server 300 determines whether or not the terminal 200 exists in a specific range for a specific period. The verification result is transmitted to the service provider, that is, the service providing apparatus 400. Based on the verification result, the service providing apparatus 400 provides a service to the terminal 200. First, the terminal 200 to be verified will be described.

  The terminal 200 acquires position time information of the terminal 200 (latitude information and longitude information in which the terminal is present and time information at the time when the position information is acquired), and signs the acquired position time information. It has a function of issuing a location certificate and performing location certification.

  In addition, the terminal 200 transmits request information (request) including location certification information (location certificate) based on the location time information of the terminal itself to the verification server 300 to satisfy a condition determined by the service provider side. The service is provided from the service providing apparatus 400 based on the result.

  Here, the terminal 200 acquires the position time information of the terminal based on the GPS signal transmitted from the GPS satellite 500. Note that the position time information acquired by the terminal 200 may be acquired in any way as long as it indicates the position of the terminal 200 itself and the time when the position information is obtained (time when the position is measured). For example, when the terminal 200 is a mobile phone device, the position of the terminal 200 may be acquired using information from a base station that can communicate with the terminal 200 as the mobile phone device. As a means for acquiring the time at which the position information is acquired, a so-called radio-controlled timepiece that receives the long time 40 kHz and 60 kHz standard time radio waves of the JJY and JG2AS stations managed by the National Institute of Information and Communications Technology. Examples include a configuration including a receiver.

  FIG. 2 is a block diagram illustrating a schematic configuration of the mobile terminal 200, the verification server 300, and the service providing apparatus 400 that configure the location certification information verification system 100.

  As illustrated in FIG. 2, the terminal 200 includes a GPS positioning unit 201, a request generation unit 203, a transmission / reception unit 205, a location certificate storage unit 207, a display / operation unit 209, the request generation unit 203, and transmission / reception. A control unit 211 that is connected to the unit 205, the location certificate storage unit 207, and the display / operation unit 209, and controls these processes.

  The GPS positioning unit 201 functions as a location time information acquisition unit that acquires location time information of the terminal 200 (location information and time information indicating the time at which the location information was acquired). Specifically, the GPS positioning unit 201 acquires the latitude, longitude, and GPS signal of the terminal 200 based on the GPS signal transmitted from the GPS satellite 500 (see FIG. 1) and including the time signal and the navigation message data. The process which calculates the time which carried out is performed. By this processing, the GPS positioning unit 201 acquires the position time information of the terminal 200 itself.

  The acquired location time information is output to the control unit 211, signed and created as a location certificate (corresponding to location certification information) and proved. The location certificate is issued so that it cannot be tampered with by the owner of the terminal 200. Thus, the location time information certified as the location certificate is saved in the location certificate saving unit 207 as needed via the control unit 211.

  The location certificate storage unit 207 is controlled by the control unit 211 and stores a location certificate generated every time the location time information of the terminal 200 is acquired via the GPS positioning unit 201. That is, the location certificate storage unit 207 stores a plurality of location certificates indicating the location and time of the terminal 200 that has moved in the past. Using these location certificates, the terminal 200 can use information such as the location where the terminal 200 has been in the past and the time at that location for verification.

  The request generation unit 203 is controlled by the control unit 211 and transmits a request to the verification server 300 to be verified by the verification server 300 in order to receive service provision from the service providing apparatus 400 (location certification information of the terminal itself). (Validation request information including).

  The display / operation unit 209 displays information on the verification server 300, the service providing apparatus 400, etc., and information for using the function of the terminal 200 itself on the verification target person (here, the user of the terminal 200), or displays the information. Based on the above, the verification target person can select a function. For example, after transmitting a request to the verification server 300, when requesting transmission of the verification result from the verification server 300, the verification result is displayed on the display portion of the display / operation unit 209 and notified to the verification target person.

  In the system 100, the transmission / reception unit 205 transmits information from the terminal 200 to the verification server 300 and the service providing apparatus 400, and receives information from the verification server 300 and the service providing apparatus 400. The transmission / reception unit 205 also transmits / receives information to / from a communication partner such as a base station.

  The control unit 211 displays the processed information on the display / operation unit 209 and controls the function of the terminal 200 based on information input from the verification target person via the display / operation unit 209.

  The control unit 211 processes the GPS signal received by the GPS positioning unit 201, acquires the location time information of the terminal itself, creates a location certificate by signing the obtained location time information, The certificate is stored in the certificate storage unit 207. The location certificate may be issued by the location certificate storage unit 207.

  In this way, the control unit 211 stores a plurality of location certificates to be issued each time the terminal acquires location time information obtained via the GPS positioning unit 201 in the location certificate storage unit 207.

  The location certificate is issued by transmitting the location time information acquired by the control unit 211 via the GPS positioning unit 201 to another device (for example, the verification server 300) serving as a certificate authority via the transmission / reception unit 205. You may make it perform from another apparatus. In this case, the terminal 200 receives a location certificate from another device and stores it in the location certificate storage unit 207. Further, the other device may be a base station when terminal 200 is a mobile phone.

  In addition, the control unit 211 generates a request including a plurality of location time information whose locations have been verified, that is, location verification information (location certificate), via the request generation unit 203. The control unit 211 transmits the generated request to the verification server 300 via the transmission / reception unit 205.

  The request generated by the control unit 211 corresponds to the service content received from the service providing device 400 on the service provider side based on the location certification information. The request in the present embodiment is to verify whether or not the terminal is in a specific range in a specific period set by the service providing apparatus 400 based on the location certification information. The verification target person who is the owner of the terminal 200 can receive the service from the service providing apparatus 400 based on the above.

  Here, the request generated by the request generation unit 203 includes a verification request ID, a verification target person ID, a location certification information list, a verification type, a location disclosure condition, the presence / absence of a location certificate in the verification result, and a verification result disclosure , And authentication information for the request (see FIG. 3). Details of the request configuration will be described later with reference to FIG.

  Note that the control unit 211 may transmit location certification information (location certificate), which is certified location time information, as a request to the verification server 300 via the transmission / reception unit 205 each time the location certification information is acquired. Alternatively, it may be stored in the location certificate storage unit 207 and a plurality of stored location certification information may be transmitted in a batch later.

Next, the verification server 300 will be described.
The verification server 300 includes a transmission / reception unit 301, a verification request management unit 303, a range verification unit 310, an absence verification unit 320, a verification result generation unit 330, and a control unit 340.

  The transmission / reception unit 301 is controlled by the control unit 340 and acquires information by transmitting information to the terminal 200 and the service providing apparatus 400 and receiving information transmitted from the terminal 200 and the service providing apparatus 400.

  The verification request management unit 303 is controlled by the control unit 340 and controls information requested for verification from the terminal 200 and the service providing apparatus 400 via the transmission / reception unit 301, that is, information that needs to be verified for service provision. Here, the verification request management unit 303 verifies the request transmitted from the verification requester / verification target side, that is, the terminal 200, and the request transmitted from the service provider side, that is, the service providing apparatus 400. It is integrated as a request (referred to as a “verification request” for convenience).

  The integrated verification request is analyzed by the control unit 340, and based on the contents, the control unit 340 causes the terminal 200 to enter a specific range within a specific period period via the range verification unit 310 or the absence verification unit 320. It is verified whether it exists. The analysis of the verification request may be performed by the verification request management unit 303, or may be performed by the verification request management unit 303 and the control unit 340.

  If the analysis content of the verification request is content requesting verification that the terminal 200 exists in a specific range / period, the range verification unit 310 determines whether the terminal 200 is in the specific range for a specific period. Validated. In addition, if the analysis content of the verification request is content that requests absence verification that requires verification that it was “absent” in a specific range / period, the absence verification unit 320 causes the terminal 200 to be in a specific range. Verify whether or not you have stayed for a certain period.

  The contents verified in this way are transmitted as verification result information to the verification requester, that is, the terminal 200, or the service provider, that is, the service providing apparatus 400.

  FIG. 3 is a conceptual diagram showing an example of the configuration of the verification request 305 managed by the verification request management unit 303 in the present embodiment. Note that the verification request 305 of the present embodiment is based on verification of whether or not the terminal 200 has been in a specific range for a service provided using the location certification information (location time information) of the terminal 200. It is shown as an example when it is supposed to be provided to the side. Therefore, the configuration of the verification request 305 is not limited to the configuration of FIG. 3 and may be configured in any manner as long as it corresponds to a service provided using location certification information.

  The verification request 305 in the present embodiment includes “verification request ID”, “verification target person ID”, “location certification information list”, “verification type”, “location disclosure condition”, “verification” as request information from the terminal 200. “Presence / absence of location certificate in result”, “verification result disclosure person”, “authentication for request”, etc. Further, the verification request 305 includes “verification target” as request information from the service providing apparatus 400.

  “Verification request ID” is used when simultaneously verifying a plurality of location certification information (location certificate) from the terminal side at the same time, and when a plurality of location certification information and requests are transmitted from the terminal side, Functions as a serial number. In other words, the “verification request ID” is given to the entire series of location certificates that the request transmitted from the terminal 200 is to be verified together with the request transmitted to the verification server 300 together. Based on this “verification request ID”, the control unit 340 identifies a series of location certification information (location certificate) to be collectively verified.

  The “verification target person ID” is information on a user who is a verification target who can receive a service using the terminal 200, and here is information on a user who owns the terminal 200. Based on the verification target person ID, the control unit 340 identifies the verification target person.

The “location certification information list” is configured from the location certificate of the terminal 200, and the location certification information (ID, location information L, time information T) indicating where and when the verification subject having the verification subject ID was present. ) Information. In FIG. 3, the location certification information list includes a plurality of obtained location certification information (specifically, location certificates), ID, location, and time (for example, location certification information 1 (ID ₁ , L ₁ ) indicating location certification information). ₁ , T ₁ ), location certification information 2 (ID ₂ , L ₂ , T ₂ ),...).

  “Verification type” is sent from the terminal side and indicates the type to be verified by the verification server 300, that is, what the terminal 200 wants the verification server 300 to verify.

  Here, as the “verification type”, if it is to verify the existence at a specific point (only whether it was in a specific place), “single”, whether it was within a specific range in the verification target There is a “range” if it is to be verified, and “absence” if it is to be verified whether it was outside the “range”. Based on this verification type, the control unit 340 determines range verification for verifying whether the terminal 200 has been in a specific range for a specific period, and absence verification for verifying that the terminal 200 has not been present.

  The “verification target” range L and the “verification target” period T are information set by the service provider side and sent from the service providing apparatus 400, and are used as verification targets of the “verification type” in the verification server 300.

  The “location disclosure condition” is “disclose” or “non-disclosure” of location certification information that is transmitted from the terminal side and used for verification of whether or not a specific period is within a specific range that is a condition for receiving a service. It is set whether or not.

  When “non-disclosure” is set in the “location disclosure condition”, the verification server 300 generates a verification result of “absence” and notifies the service providing apparatus 400 of the verification result. Notify the certification information, only the “absence” verification result. As a result, the verification target person (terminal 200) proves only the absence when the verification result is “absent”, and prevents the service provider side, that is, the service providing apparatus from notifying the user of the presence. .

  On the other hand, when “disclosure” is set in the “location disclosure condition”, when the verification result of “absence” is generated in the verification server 300, the position of the location etc. at the time of the condition, The time information is notified to the service providing apparatus 400 by the control unit 340 via the transmission / reception unit 301 together with the verification result of “absence”.

  “Presence / absence of location certificate in verification result” is information sent from the terminal side, and a list of location certification information to be verified is sent to the verification server 300, but the sent information itself is passed to the service provider side. Whether or not is set. That is, when “No” is set in “Presence / absence of location certificate in the verification result”, the verification server 300 discloses only the verification result to the verification result disclosing person by the control unit 340 and “Yes” is selected. If it is, the location certificate, that is, the information of the verification target data itself including the location certification information indicating the location and time is passed.

  The “verification result disclosing person” sets who the verification result is to be passed to, and “verification requester”, “service provider”, and the like are set.

  That is, in the terminal 200, when the verification result obtained by the verification is returned to the verification server 300 for the time being, the terminal 200 sets the “verification requester” to the service provider side, That is, when the service providing apparatus 400 is also notified directly, “service provider” is set. In response to this, the verification server 300 sends the verification result to the destination corresponding to the “verification requester” and “service provider” set in the “verification result target person”.

  “Authentication for Request” is “Verification Request ID”, “Verification Target ID”, “Location Certification Information List”, “Verification Type”, “Verification Target”, “Location Disclosure Condition”, “Location Verification to Verification Result” This is to indicate who has sent the request information for all of the request information such as “document presence / absence”, “verification result disclosure person”, and “authentication for request”.

  The “authentication for the request” of the verification request 305 is “verification request ID”, “verification target person ID”, “location certification information list”, “verification type”, “location disclosure condition”, “verification result” This indicates that request information such as “the presence / absence of a location certificate”, “verification result disclosure person”, “authentication for a request”, and the like has been sent from the terminal 200.

  The “authentication for the request” when sent from the terminal 200 includes, for example, a signature in the terminal 200. When the authentication information for the request constitutes a request transmitted from the terminal 200, the terminal 200 has an IC There is a configuration in which information is obtained from the IC card by providing a card or the like. When a request including such authentication information is transmitted to the verification server 300, the verification server 300 performs either a required range verification or absence verification process based on the “verification type” of the request. The result may be generated, a signature may be added to the verification result, and the result may be transmitted to at least one of the terminal 200 and the service providing apparatus 400. When transmitted to the provider side, it is confirmed that the signature issuance source is the verification server 300. Based on the verification result, it is verified whether or not the user of the terminal 200 is in a specific place, and the service is provided to the user. I will provide a.

  The range verification unit 310 is controlled by the control unit 340, and when “range” is set in the “verification type” as the analysis result of the verification request 305, it is considered that the range verification unit 310 has requested a range verification as to whether it was in a specific range. The verification request 305 is used to verify whether the location certification information of the terminal 200 exists in a specific place for a specific period.

Here, the range verification unit 310 uses the k location certification information, that is, the k location certificates sent from the terminal 200, and the “verification target” range _LR and the “verification target” included in the verification request 305. It verifies that the terminal 200 exists in the period T _R (period start T _Rs , period end T _Re ).

In particular, the range verifying unit 310 includes a location verification information of the terminal 200 in the verification request 305 (see FIG. 3), based on the "verified" range L _R and "verified" period T _R, the position verification information The position indicated by (location certificate) and the time (time) at this position are individually verified. If both of these verification results are successful, the range verification unit 310 determines that the verification is successful.

Verification of position for the range verifying unit 310, the position L _1, L 2 indicated are k position verification information, _..., L _k is performed for determining whether or not fit in "verified" range L _R, if fit ({L ₁ , L ₂ ,..., L _k } ⊆L _R ) The verification is successful.

As a specific position verification method performed by the range verification unit 310, for example, the following two methods are conceivable.
1. When using latitude / longitude information such as GPS The range verification unit 310 acquires the latitude / longitude information such as GPS by specifying the reference longitude / latitude X and Y and the allowable distance D from the reference point as the “verification target” range L Then, it is verified by confirming that L ₁ (X ₁ , Y ₁ ) −L _k (X _k , Y _k ) is included within the allowable distance D from the points X and Y.

2. When acquiring and using address information from a base station, etc. The range verification unit 310 acquires and specifies a reference address: Kana ○ Prefectural Yokohama △ Hama City Shin × Hama} as a “verification target” range from a base station, Confirm that the upper part of the address of L ₁ (Kana ○ prefecture side △ city new △ beach 1-1)-L _k (Kanna ○ prefecture side △ city new △ beach 2-4) matches the standard address. To verify.

It is also in the scope verifying unit 310, the verification of the time taken in conjunction with the verification of the location, the time T _1, T 2 indicated are k position verification information, _..., whether T _k falls within a "verified" period T _R If it falls within the range ({T ₁ , T ₂ ,..., T _k } ⊆T _R ), the verification is successful.

During the verification of this time, the range verification unit 310 has the position verification information that is the “verification target” satisfying ({T ₁ , T ₂ ,..., T _k } ⊆T _R ) in the “verification target” period. time _{(T Rs, T 1, T} 2, ..., T k, T Re) indicating of, when it exceeds the allowable time Delta] t the difference [Delta] T is set in advance between successive times (ΔT> Δt), as a verification failure Also good. This process, in the terminal 200 is within a specific time period T _R in a specific range L _R, even if only was there a period which does not satisfy the specific time period T _R, can be accurately verified, the terminal 200 is a particular time period T It is verified that it was not over _R. For example, a 5-minute particular period T _R, actually a case period terminal 200 was in the specific range L _R is 1-2 minutes, can be verified as the verification failed those not there 5 minutes.

  The content verified by the range verification unit 310 is output to the verification result generation unit 330 by the control unit 340.

Further, in the range verification unit 310, when the “verification target person ID” is included in the verification request 305 (see FIG. 3), the location verification information ID (eg, ID ₁ , ID ₂ etc.) in the “location verification information list” If they do not match, the verification fails, and the content to that effect is output by the control unit 340 to the verification result generation unit 330.

  The absence verification unit 320 is controlled by the control unit 340 and, when “absence” is set in the “verification type” in the analysis result of the verification request 305, requests for absence verification as to whether or not the specific range / period was present. The verification request 305 is used to verify whether the location certification information of the terminal 200 has been absent at a specific location for a specific period.

Here, the absence verification unit 320 uses the “k” location certification information, that is, the “k” location certificates sent from the terminal 200 to use the “verification target” range L included in the verification request 305 (see FIG. 3). It is verified that 0 does not exist in _A and period T _A (period start T _As , period end T _Ae ).

Specifically, absent the verification unit 320, the position verification information of the terminal 200, based on the "verified" range L _A and "verified" period T _A, the position verification information (position certificates) of the position shown Verification and time (time) verification at this position are performed separately. When these individually verified results are both successful, the absence verification unit 320 determines that the verification is successful.

Verification of position for the absence verifying unit 320, the position _{L 1,} L 2 indicated are k position and time information, ..., _{if L k} is not within the verification target range _{L A ({L 1, L} 2, ..., If you do not meet the L _k} ⊆L _a), and the verification is successful.

Also, if in the absence verification unit 320, verification of the time for the along with the verification of the location, the time T _1, T 2 indicated are k position verification information, _{which ...,} T _k does not fit the "verified" period T _A ( _{{T 1, T 2, ...} , T k} is not satisfied ⊆T _a), the verification is successful.

  The contents verified by the absence verification unit 320 in this way are output to the verification result generation unit 330 by the control unit 340.

Further, in the absence verification unit 320, when the verification target person ID is included in the verification request 305 (see FIG. 3), the position information ID (for example, ID ₁ , ID ₂ etc.) in the position certification information list does not match. In this case, the verification is failed, and the fact is sent to the verification result generation unit 330 by the control unit 340.

  The verification result generation unit 330 is controlled by the control unit 340 and generates a verification result disclosed by being transmitted to the service providing apparatus 400 based on the verification result by the range verification unit 310 or the absence verification unit 320.

  Specifically, the verification result generation unit 330 outputs the verification result to be disclosed to the verification request 305 (see FIG. 3) set in the “verification result disclosing person” (verification requester, service provider, etc.). Generate.

  The verification result generated by the verification result generation unit 330 includes, in addition to the verification contents of verification success or verification failure, the location certification information to be verified or the hash value of this location certification information, and the request for the verification request 305 (see FIG. 3). It may be generated including information. Thereby, when the verification result is disclosed, the traceability of the terminal 200 can be improved.

  Further, when the location verification information is included in the verification result, other acquired information acquired by the terminal 200 may be attached. The acquired information includes camera image, audio information, gyro information, body authentication (Biometrics) information, various sensor information such as angle, acceleration, and humidity of the terminal 200, operation information such as key operation and opening / closing operation, and the like. Can be mentioned.

  In the acquired information, the gyro information, the body authentication information, the sensor information, etc. are sensors such as a gyro attached to the terminal 200, a fingerprint, an iris, a palm, etc. for checking whether the user exists with the terminal 200. Etc.

  Further, these pieces of acquired information may be used as parameters in service provision provided to the terminal 200. In this case, the request transmitted from the terminal 200 to the verification server 300 includes the acquired information, and the verification server 300 verifies the acquired information including the acquired information, and verifies the result to the service providing device 400 on the service provider side. Send as a result. By using this, the service provider side can provide the verification target person with a service in which the acquired information is included in the verification target.

  Furthermore, when including the location time information in the verification result, the verification result generation unit 330 may add a digital signature or a MAC (Message Authentication Code) to the location time information. Thereby, the confidentiality of the verification result can be improved with respect to other than the terminal 200 and the service providing apparatus 400.

  Further, in the verification result generation unit 330, when the position verification request 305 (see FIG. 3) includes a position non-disclosure request, that is, when “non-disclosure” is set in the “position disclosure condition”, A verification result that does not include the location certification information of the terminal 200 and the location L and time T indicated by the location certification information is generated. Thereby, the verification server 300 can prove only that the terminal 200 was absent within a specific range and period.

  The control unit 340 acquires a request transmitted from the terminal 200 or the service providing apparatus 400 via the transmission / reception unit 301, and centralizes and analyzes the request 305 to be verified (see FIG. 3) in the verification request management unit 303. .

  In addition, the control unit 340 performs verification using the range verification unit 310 or the absence verification unit 320 in response to the range verification request and the absence verification request included in the integrated verification request 305 (see FIG. 3), and the verification A verification result generation unit 330 generates a verification result based on the content. Further, the control unit 340 discloses the generated verification result by transmitting it to the terminal 200 or the service providing apparatus 400 via the transmission / reception unit 301.

  When the control unit 340 analyzes the verification request 305, if the verification request 305 (see FIG. 3) includes a location non-disclosure request, a plurality of location certification information and these location certification information are transmitted via the verification result generation unit 330. The verification result is generated without including the position L and time T indicated by. As a result, the verification server 300 proves the absence to the service providing apparatus 400, but it is possible not to reveal where it existed during the absence. In other words, the verification server 300 can disclose only the absence to the service provider.

  When the control unit 340 discloses the verification result by transmitting it to the “verification result disclosing person (for example, server provider)” via the transmission / reception unit 301, the control unit 340 adds the digital signature of the verification server 300 to the verification result. May be transmitted and disclosed. Accordingly, the “verification result disclosing person” can determine that the verification result to be transmitted is performed by the verification server 300 and can confirm the accuracy of the verification result.

Next, the service providing apparatus 400 will be described.
The service providing apparatus 400 verifies the verification information of the verification target person (including the positional information and the time information at the time when the positional information is obtained) with respect to the verification target person who has the terminal 200, specifically the terminal 200. It is used to provide a service to the terminal 200 based on the result. Here, the service providing apparatus 400 provides a service to the terminal 200 based on the verification result of whether the terminal 200 has been in a specific range for a specific period.

  For example, charging in the case where the verification target person who is the owner of the terminal 200 is in a specific area such as a theme park, and the work proof of where the worker is working with the owner of the terminal 200 as the worker In addition, there is a service for disclosing confirmation to a third party of confirmation of when and where the user is, by confirming the location of the dumping of the garbage and giving the child the terminal 200.

  As shown in FIG. 2, the service providing apparatus 400 includes a transmission / reception unit 410, a verification unit 420, a service providing unit 430, a service-compatible verification target generation unit 440, and a control unit that controls each unit 410, 420, 430, 440. 450.

  The transmission / reception unit 410 is controlled by the control unit 450 and transmits information to the terminal 200 and the verification server 300 and receives information transmitted from the terminal 200 and the verification server 300.

  The verification unit 420 is controlled by the control unit 450 and verifies the verification result transmitted from the verification server 300 via the transmission / reception unit 410. When the digital signature of the verification server 300 is added to the verification result sent from the verification server 300, the verification unit 420 can verify the digital signature and confirm the certainty of the verification result sent.

  The service providing unit 430 is controlled by the control unit 450 and includes information on a service to be provided to the verification target person who owns the terminal 200, and the information is sent to the user terminal 200 according to the verification result.

  Specifically, the service providing unit 430 determines whether the verification target person exists within a specific range for a specific period based on the position certification information of the verification target person's terminal 200, that is, the position information and the time information when the position exists. The service information to be provided to the verification target person is included depending on whether or not. A service based on the service information is provided to the verification counselor having the terminal 200 by the control unit 450.

  The verification target generation unit 440 is controlled by the control unit 450 and generates “verification target” request information to be verified by the verification server 300 corresponding to the service to be provided.

In this embodiment, since the verification is performed by the verification server 300, as the verification target information transmitted to the verification server 300, the verification target range L and the verification target period T (the “verification target” range in the verification request 305). L _R , L _A and “verification target” period T _R , T _A ) are generated based on information from the service providing unit 430.

  In order to provide the service, the control unit 450 transmits the request information of “verification target (range, period)” generated by the verification target generation unit 440 to the verification server 300. In addition, the control unit 450 verifies the verification result from the verification server 300 using the verification unit 420, and if the service providing condition from the service providing unit 430 is satisfied, based on the information from the service providing unit 430, A service is provided to the terminal 200.

  Next, in the location certification information verification system 100, the verification processing of the location certification information of the verification server 300 will be described mainly using FIG. 1 and FIG.

  In the location verification information verification system 100 shown in FIG. 1, the terminal 200 of the location verification information verification requester (here, the terminal owner and also the verification target) acquires the location time information from the GPS satellite 500, A plurality of location certificates (location certification information) including the location and the time at which the location was located are created and stored in the location certificate storage unit 207 (see FIG. 2). When the verification requester receives a service using the location certificate with the verification requester as the verification target, the terminal 200 transmits information to be verified to the verification server 300 in order to receive the service.

  Specifically, as illustrated in FIG. 2, the terminal 200 uses the position time information (location certificate) of the location certificate storage unit 207 to cause the request generation unit 203 to send a request including location certification information by the control unit 211. Generate. The generated request is transmitted to the verification server by the control unit 211 via the transmission / reception unit 205. Here, in the request generated in terminal 200, a plurality of location certification information indicating the acquired points are included in the location certification information list.

  In the verification server 300 that has received the request including the location time information (location certificate) via the transmission / reception unit 301, the control unit 340 verifies the request from the terminal side and the service transmitted from the service providing device side. The verification request management unit 303 controls the target (here, the range L and the period T). The integrated verification request 305 (see FIG. 3) is verified by the range verification unit 310 or the absence verification unit 320 based on the request content. Specifically, when the “verification type” is set to “single” or “range” request in the verification request 305, the control unit 340 verifies the range of the verification request 305 with the range verification unit 310, and the “absence” request If set, the control unit 340 verifies the absence of the verification request 305 by the absence verification unit 320.

  FIG. 4 is a flowchart showing range verification processing in the position certification information verification system 100 according to the present embodiment.

  In the verification server 300, as shown in step S1, the control unit 340 analyzes the verification request 305 (see FIG. 3) including the request of the terminal 200 and the information of the service providing apparatus 400 acquired through the transmission / reception unit 301, The process proceeds to step S2.

  In this step S1, it is analyzed that the “verification type” request is “range”, and the contents of the verification request 305 (see FIG. 3) such as what range verification is requested by the terminal 200 are analyzed. . Here, since the range request is set in the request, the control unit 340 performs verification after the next processing in the range verification unit 310.

In step S2, the range verification unit 310 uses the “location certification information list” and “verification target (range L)” among the pieces of request information constituting the verification request 305 (see FIG. 3). The position of the terminal 200 indicating whether or not it is in a specific range is verified, and the process proceeds to step S3. Specifically, in step S2, the positions L ₁ , L ₂ ,..., L _k indicated by the k pieces of location certification information in the “location certification information list” of the validation request 305 (see FIG. 3) are the validation request 305 (FIG. 3 reference) to verify whether or not fit in the "verified" range L _R of.

In step S3, the range verification unit 310 uses the location certification information list and the verification target (period T) among the pieces of request information constituting the verification request 305 (see FIG. 3), particularly the location time information ( Specifically, based on the time information included in the location certificate, the terminal 200 verifies the time indicating whether or not the terminal 200 was in a specific period T. Specifically, in step S3, the times T ₁ , T ₂ ,..., T _k indicated by the k pieces of position time information in the “location certification information list” of the verification request 305 (see FIG. 3) are the verification request 305 ( It performed whether fits in "verified" period T _R determined in reference to FIG. 3), after the step S3, the process proceeds to step S4.

In step S4, the range verification unit 310 verifies the time interval for verifying the difference between the times corresponding to the plurality of pieces of position information in the position certification information list within a preset time. Do. Specifically, in step S4, the range verification unit 310 satisfies ({T ₁ , T ₂ ,..., T _k } ⊆T _R ) in the “verification target” period of the verification request 305 (see FIG. 3). Whether or not the difference ΔT between successive times out of the times (T _Rs , T ₁ , T ₂ ,..., T _k , T _Re ) indicated by the location verification information as “verification target” exceeds a preset time Δt. Verify that.

  The result verified in this way is generated as a verification result to be sent to the service providing apparatus by the verification result generation unit 330 by the control unit 340.

  As a verification result, if all the conditions are satisfied in step S2 to step S4, the verification is successful, and the verification target person generates a verification result indicating that it exists in a specific range / period. If these conditions are not satisfied, the verification fails, and a verification result indicating that the verification target person did not exist in a specific range / period is generated.

  FIG. 5 is a flowchart showing the absence verification process in the location certification information verification system 100 according to the present embodiment.

  In the verification server 300, as shown in step S11, the control unit 340 analyzes the verification request 305 (see FIG. 3) including the request of the terminal 200 and the information of the service providing apparatus 400 acquired through the transmission / reception unit 301, The process proceeds to step S12.

  In this step S11, it is analyzed that the “verification type” request is “absent”, and the contents of the verification request 305 (see FIG. 3) such as what kind of absence verification the terminal 200 is requesting are analyzed. . Here, since the absence request is made in the request, the control unit 340 causes the absence verification unit 320 to perform verification after the next process.

  In step S12, the absence verification unit 320 uses the “location certification information list” and “verification target (range L)” among the pieces of request information constituting the verification request 305 (see FIG. 3), and the terminal 200 The position of the terminal 200 indicating whether it was not in the specific range is verified, and the process proceeds to step S13.

Specifically, in step S12, the verification request 305 position shown are k position and time information in the "position verification information lists" (see FIG. _{3) L 1, L 2, ...} , L k is fit in the verification target range _{L A} ({L ₁ , L ₂ ,..., L _k } ⊆L _A is not satisfied).

In step S13, the absence verification unit 320 uses the location certification information list and the verification target (period T) among the pieces of request information constituting the verification request 305 (see FIG. 3), and uses the location time information of the terminal 200 ( In detail, based on the time information included in the location certificate, the terminal 200 verifies the time indicating whether the terminal 200 was not in the specific period T. Specifically, in step S13, times T ₁ , T ₂ ,..., T _k indicated by k pieces of location certification information in the “location certification information list” of the verification request 305 (see FIG. 3) are “verification target” periods. do not within the _{T a ({T 1, T} 2, ..., T k} or not satisfied ⊆T _a) a determination is, after this step S13, the process proceeds to step S14.

  In step S14, the control unit 340 is absent when the verification result generation unit 330 uses the plurality of position time information to generate the verification result using the verification data of both the position and the time at the position. The location non-disclosure process that does not disclose the location time information at that time is performed.

  The processing in step S14 is processing performed when a “non-disclosure” request is set in the position disclosure condition constituting the verification request 305 (see FIG. 3) as a result of the analysis of the verification request 305 (see FIG. 3). It is. As a result, a verification result that does not include the position / time indicated by the position / time information of the verification target person and the position / time information is generated.

  The verification result generated based on the range verification or absence verification generated in this way is transmitted to the service providing apparatus 400 via the transmission / reception unit 301 when the verification result disclosing person includes a service provider.

  Upon receiving this verification result, the service providing apparatus confirms the contents, and provides the service to the terminal 200 if the service conditions are satisfied.

  Further, according to the above configuration, in the absence verification, the verification server can transmit only the absence to the service providing apparatus, thereby enhancing anonymity.

  As described above, in the location verification information verification system 100 according to the present embodiment, the verification server 300 determines the location L and time T of the plurality of location verification information included in the request from the terminal 200 as the verification request 305 (see FIG. 3). It is verified that it falls within or does not fall within the verification target range / period.

  That is, when the verification server 300 verifies whether or not the terminal 200 exists within the specific range and the specific period using the plurality of position certification information of the terminal 200, the multiple positions exist within the specific range. Position verification that determines whether or not a plurality of times that are verified by this position verification and a plurality of times that respectively correspond to a plurality of positions that are verified by this position verification are verified and determined collectively Time verification is performed separately. Then, the verification content is generated as a verification result and transmitted to the service providing apparatus 400 and disclosed.

  When the verification server 300 verifies that a plurality of positions exist in the specific range in the position verification and that a plurality of times are in the specific period in the time verification, it is assumed that the terminal 200 exists in the specific range / period A verification result can be generated. Further, when it is verified that a plurality of positions do not exist within the specific range in the position verification, or a plurality of times do not exist within the specific period in the time verification, the verification that the terminal 200 does not exist in the specific range / period The result can be generated.

  Therefore, using the position information as the presence information of the terminal 200 and the time information at the time when the position information is obtained, it can be accurately verified whether or not the owner of the terminal 200 has been in a place within a specific range for a specific period. .

  Accordingly, not only the verification server 300 but also the service providing apparatus 400 that receives the verification result of the verification server 300 can quantitatively evaluate the presence or absence of the terminal 200 in the specific range / period. In addition, the service can be provided to the terminal 200, that is, the verification target person by accurately confirming whether the terminal 200 is present or absent in the verification target range and the verification target period.

  In the present embodiment, terminal 200 includes location time information acquired and certified from GPS satellite 500 in the request as a “location certification information list”, and collectively transmits it to a verification server as a verification request partner. Although it was set as the structure, it is not restricted to this. For example, the terminal 200 may be configured to transmit the position time information to the verification server 300 every time it is acquired. In this case, the verification request ID is inserted as the same verification request ID in order to indicate that it is a series of information in the request transmitted from the terminal 200 to the verification server for each acquisition of position time information. With this verification request ID, the verification server can analyze that a plurality of requests sent from the terminal 200 are a series of information.

  As described above, the verification server 300 can be verified every time the location time information is acquired in the terminal 200, that is, the location time information of the terminal 200 can be verified in real time, and a plurality of the terminals 200 can be acquired and stored as location certificates. In this case, a plurality of saved location time information can be sent from the terminal 200 and verified later.

  The range verification performed in the verification server 300 may be performed on the service provider side.

  In this case, a configuration in which the service providing device has a function as a verification server or a configuration in which the verification server itself is used as a device on the service provider side together with the service providing device can be considered.

  Also, the terminal 200 is provided with a PIN authentication device or a biometric authentication device, and the terminal 200 periodically or when acquiring position time information from a GPS satellite for the terminal holder, that is, a verification target person, performs PIN authentication or biometric authentication. May be requested periodically. That is, in the terminal 200, the location certificate is created by a periodic operation of the verification target person. Needless to say, PIN authentication and biometric authentication may be performed via the display / operation unit 209.

  Thereby, the terminal 200 can confirm periodically that the person to be verified exists in the vicinity of the terminal. For example, when the positions indicated by the position time information transmitted to the verification server 300 match at a certain number or more, the verification server 300 can confirm that the verification target person has left the terminal 200.

  Specifically, the presence of the person to be verified can be confirmed by providing the terminal 200 with a gyro and including the data acquired from the gyro in the verification request 305 (see FIG. 3). That is, in the data acquired from the gyro, when the inclination does not change, it is determined that there is no verification target person around the terminal, and the provision of the service can be stopped.

  Further, a configuration may be adopted in which the terminal 200 is provided with a sensor that allows a person to be verified to hold a personal wireless device, makes a pair with the personal wireless device, and recognizes the personal wireless device only within a certain range. Based on the information from the sensor, the terminal 200 is controlled so as to acquire the position time information only when a personal wireless device exists around the sensor, that is, when there is a person to be verified around the terminal including the sensor. Accordingly, when the verification target person has left the terminal 200, the terminal 200 does not acquire the location time information, and therefore does not issue the location certificate and does not perform the process for receiving the service. Note that the personal wireless device that is paired with the sensor may be worn by the person to be verified as an accessory such as a watch, necklace, or ring.

  The location time information verification server according to the first aspect of the present invention comprises: acquisition means for acquiring location information of a predetermined mobile terminal transmitted from a communication partner and time information indicating the time when the location information is obtained; Verifying whether the mobile terminal exists within a specific range and a specific period using the location information and the time information acquired by the acquisition unit, and verification contents by the verification unit, A verification result generation unit that generates a verification result that is transmitted to and disclosed at least one of a mobile terminal and a communication partner other than the mobile terminal, and the verification unit includes a plurality of positions indicated by a plurality of the position information. The position verification for determining whether or not it exists within the specific range, and a plurality of times indicated by the plurality of time information respectively corresponding to the plurality of position information verified by the position verification are the special characteristics. Take individually performed configuration and determining the time verifying whether present in the period.

  According to this configuration, when verifying whether a mobile terminal exists within a specific range and a specific period using a plurality of position information and time information of the mobile terminal, a plurality of positions indicated by the plurality of position information Whether or not a plurality of times indicated by a plurality of pieces of time information corresponding to a plurality of pieces of position information verified by the position verification and the plurality of pieces of position information verified by the position verification exist within a specific period. It verifies by performing time verification to determine whether or not, and the verification content is generated as a verification result and transmitted to and disclosed at least one of the mobile terminal and a communication partner other than the mobile terminal.

  In the position verification performed in this way, when a plurality of positions exist within a specific range, and a time verification verifies that a plurality of times are within a specific period, verification that a mobile terminal exists within the specific range / period The result can be generated. Also, if the location verification verifies that multiple locations do not exist within the specified range, or if the time verification verifies that multiple times do not exist within the specified period, verification that there is no mobile terminal in the specified range / period The result can be generated.

  Therefore, it is possible to accurately verify whether or not the owner of the mobile terminal has been in a location within a specific range for a specific period by using the location information as the presence information of the mobile terminal and the time information at the location indicated by the location information.

  In the position verification and time verification, a plurality of position information and time information to be verified are collectively verified with respect to the target range and the target period. As a result, the location of the mobile terminal can be verified in real time if a plurality of location information and time information are acquired from the mobile terminal in real time each time it is transmitted from the mobile terminal. If the location information and the time information are transmitted at once, it is possible to verify whether the terminal has been in the past within a specific range / period.

  The location time information verification server according to the second aspect of the present invention is the above configuration, wherein the location information and the time information are certified location certification information from the mobile terminal to request verification by the verification means. Included in the verification request information to be transmitted, the acquisition unit acquires the verification request information from the mobile terminal, and the verification unit performs verification based on the verification request information acquired by the acquisition unit Take.

  According to this configuration, the verification request information is acquired from the mobile terminal, and using the location information and time information of the mobile terminal included in the acquired verification request information, whether the mobile terminal exists within a specific range and a specific period. It can be accurately verified whether or not.

  In the position time information verification server according to the third aspect of the present invention, in the configuration described above, when the verification unit performs time verification, a difference between a plurality of consecutive times within the specific period is preset. It is determined whether or not an allowable time is exceeded, and when the difference exceeds the allowable time, the verification result generation unit generates the verification result on the assumption that the mobile terminal does not exist within the specific period. take.

  According to this configuration, when a difference between a plurality of consecutive times within a specific period exceeds a preset allowable time, a verification result is generated assuming that the mobile terminal does not exist within the specific period. Even when a mobile terminal does not exist within a specific period, the mobile terminal is accurately verified, and the terminal is disclosed as not existing within a specific range / period.

  The location time information verification server according to a fourth aspect of the present invention is the above configuration, wherein the verification result generation unit is configured such that the verification unit does not cause the mobile terminal to exist within the specific range within the specific period. When it is determined, a configuration is adopted in which the location information and the time information of the mobile terminal are not included in the verification result to be generated.

  According to this configuration, when the mobile terminal does not exist within the specific range within the specific period, the location information and time information of the mobile terminal during that period are not disclosed, and the mobile terminal was absent within the specific range / period. Can only be disclosed.

  The mobile terminal according to the fifth aspect of the present invention includes a location time information acquisition unit that acquires a plurality of location information and time information at the time of obtaining the location information, and a location where the obtained location information and time information are certified. Location verification information storing means for storing as certification information, and verification of whether or not the position and time indicated by each of the plurality of location certification information exist within a specific range and a specific period, including a plurality of the location certification information A verification request information generating unit that generates verification request information to be transmitted; and a transmission unit that transmits the verification request information to another device.

  According to this configuration, by transmitting the verification request information to the other device, it is possible to cause the other device to accurately verify whether the mobile terminal itself exists within the specific range and the specific period.

  The location certification information verification system according to the sixth aspect of the present invention acquires location information and a plurality of time information indicating the time at which the location information was obtained and proves it as location certification information, and a plurality of the location certification information Based on a verification result of the location time information verification server, a location time information verification server that verifies the location of the mobile terminal using a plurality of location certification information transmitted from the mobile terminal A service providing device that provides a service to the mobile terminal, and the location time information verification server uses the acquisition unit that acquires the location verification information, and the location verification information acquired by the acquisition unit, Verification means for verifying whether the mobile terminal exists within a specific range and a specific period, and verification contents by the verification means, the mobile terminal and the service providing device A verification result generation unit that generates a verification result that is transmitted to and disclosed at least one of the plurality of positions, and the verification unit includes a plurality of positions indicated by the position information of the plurality of position verification information within the specific range. Whether or not a plurality of times indicated by a plurality of time information respectively corresponding to the position information of the plurality of position verification information verified by the position verification exists within the specific period The time verification for determining whether or not is separately performed.

  According to this configuration, the location time information verification server verifies whether the mobile terminal exists within a specific range and a specific period, using the location information and time information in the plurality of location certification information of the mobile terminal. At the time of this verification, the position time information verification server determines whether or not a plurality of positions indicated by a plurality of position information exist within a specific range, and a plurality of position information verified by this position verification. And time verification for individually determining whether or not a plurality of times indicated by a plurality of time information corresponding to each exists within a specific period. The location time information verification server generates the verified content as a verification result, and transmits it to at least one of the mobile terminal and the service providing device for disclosure. In the position verification and time verification, the position time information verification server collectively verifies a plurality of position information and time information to be verified with respect to the target range and the target period.

  In the position verification performed in this way, when a plurality of positions exist within a specific range and when it is verified that a plurality of times are within a specific period in time verification, a verification result that a terminal exists in the specific range / period Can be generated. In addition, if it is verified that multiple positions do not exist within a specific range in position verification or multiple times do not exist within a specific period in time verification, a verification result that no terminal exists in the specific range / period Can be generated. Therefore, it is possible to accurately verify whether or not the owner of the mobile terminal has been in a location within a specific range for a specific period by using the location information as the presence information of the mobile terminal and the time information at the location indicated by the location information.

  In the position verification and time verification, a plurality of position information and time information to be verified are collectively verified with respect to the target range and the target period. As a result, the location of the mobile terminal can be verified in real time if a plurality of location information and time information are acquired from the mobile terminal in real time each time it is transmitted from the mobile terminal. If the location information and the time information are transmitted at once, it is possible to verify whether the terminal has been in the past within a specific range / period.

  The location certification information verification system according to a seventh aspect of the present invention is the above configuration, wherein the location certification information is included in verification request information transmitted from the mobile terminal, and the location time information verification server is configured to acquire the location certification information. When the means acquires the verification request information, the verification means verifies the location certification information.
