[1. Overview]
First, the configuration and function of the suspicious person detection device 100 according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration example of the suspicious person detection device 100 according to the present embodiment.

The suspicious person detection device 100 according to the present embodiment is a device for identifying a person who is likely to be a suspicious person in advance and preventing the suspicious person from entering the country. The suspicious person detection device 100 according to the present embodiment determines from the travel agency used by the traveler to arrange an airline ticket whether or not the traveler who is about to enter the country is likely to be a suspicious person. .. For example, a travel agency that has arranged tickets for terrorists, criminals, etc. in the past may repeatedly arrange tickets for such persons. The suspicious person detection device 100 according to the present embodiment identifies a person who is likely to be a suspicious person based on reservation information including information about a travel agency used by a traveler (also referred to as "travel agency information"). do.

More specifically, the suspicious person detection device 100 has a collation unit 110 and a determination unit 120, as shown in FIG. The collation unit 110 collates the traveler's authentication information acquired at the departure point with the traveler's authentication information acquired at the destination. The determination unit 120 determines whether or not the traveler is a suspicious person based on the travel agency information included in the travel agency reservation information associated with the collated authentication information.

As a result, the suspicious person detection device 100 can determine whether or not there is a high possibility of a suspicious person before the traveler enters the country. As a result, for a person who is highly likely to be a suspicious person, it is possible to take measures such as strict immigration inspection, and it is possible to prevent the entry of a suspicious person. In addition, it can be determined that it is not necessary to strictly carry out immigration inspection for a person who is unlikely to be a suspicious person. Therefore, it is possible to determine whether or not immigration inspection should be carried out strictly according to the possibility of a suspicious person, and it is also possible to carry out immigration inspection efficiently.

[2. Device configuration]
The configuration and the function of the suspicious person detection device 100 according to the present embodiment will be described with reference to FIGS. 2 to 4. FIG. 2 is an explanatory diagram showing an outline of processing by the suspicious person detection device 100 according to the present embodiment. FIG. 3 is a block diagram showing a configuration example of the suspicious person detection device 100 according to the present embodiment. FIG. 4 is an explanatory diagram showing an example of a credit list recorded in the travel agency DB23.

As shown in FIG. 2, the suspicious person detection device 100 according to the present embodiment is for a traveler heading from a departure point to a destination by using a means of transportation such as an airplane, for example, a terrorist or a terrorist before entering the country at the destination. Determine whether or not there is a high possibility of being a criminal such as a criminal. Therefore, at the departure point, the traveler information of the traveler is acquired and recorded in the management server 20. In addition, the credit list of the travel agency is recorded on the management server 20. The travel agency credit list is a list of travel agencies that have arranged tickets for terrorists, criminals, etc. in the past. The suspicious person detection device 100 increases the possibility that the traveler is a suspicious person based on various information of the management server 20 connected via the network 5 and the authentication information of the traveler acquired at the destination. judge.

The determination result by the suspicious person detection device 100 can be used, for example, to determine the necessity of strictly performing immigration inspection. If it is determined that the traveler is likely to be a suspicious person, it is necessary to carry out strict immigration examination. It is desirable that the government guides you to the corresponding immigration booth. In addition, if it is determined that the traveler is unlikely to be a suspicious person, it is unlikely that the immigration inspection will be carried out rigorously. May guide you to the corresponding immigration booth.

In this way, based on the determination result by the suspicious person detection device 100, it is possible to allocate travelers to an appropriate immigration gate or immigration booth according to the possibility of being a suspicious person. As shown in FIG. 2, for example, the distribution of travelers may be performed by guiding the travelers using the guidance terminal 30 installed at the immigration checkpoint. Alternatively, the determination result of the suspicious person detection device 100 may be notified to the immigration gates 41 to 43, and the strictness of the immigration examination may be changed according to the possibility of being a suspicious person. You may refuse immigration of a person with a high score.

By using the suspicious person detection device 100, it is possible to prevent the suspicious person from entering the country and to determine whether or not the immigration examination should be strictly carried out according to the possibility of the suspicious person. It is also possible to carry out immigration inspections often.

FIG. 3 shows a configuration of a suspicious person detection system constructed by using the suspicious person detection device 100 according to the present embodiment, and a configuration example of the suspicious person detection device 100. In the suspicious person detection system, as shown in FIG. 3, the suspicious person detection device 100 communicates with the traveler information server 10, the management server 20, the guidance terminal 30, the immigration gate 40, the immigration terminal 50, and the like via the network 5. It is connected and configured.

The traveler information server 10 is a server managed by an airline company or the like, and records the traveler information of the traveler acquired at the departure point. The traveler information server 10 records, for example, the biometric information of the traveler, the name, and the information of the travel agency that arranged the airline ticket, which was acquired at the time of check-in at the airport of the departure place. The biological information of the traveler is, for example, information such as a face, a fingerprint, an iris, and a vein, and can be obtained from the traveler at the time of check-in or before, for example. The biological information is acquired as an image or video by, for example, an imaging device, and is retained as the acquired image or video or a feature amount extracted from the acquired image or video. The name of the traveler, information on the travel agency, etc. can be obtained from API (Advance Passenger Information; Advance Passenger Information) and PNR (Passenger Name Record; Passenger Reservation Record).

The API includes, for example, information such as name, nationality, date of birth, passport number, departure place, final destination, and gender. The PNR includes, for example, information about the person making the reservation (name, nationality, date of birth, etc.), information about the contents of the reservation (travel agency that made the reservation, reservation date, ticket number, date of issue, etc.), Information such as information on the reservation person's personal belongings (number of personal belongings, weight, etc.), information on the procedure for the reservation person to board the aircraft (time when the boarding procedure was completed, etc.), etc. are included.

The traveler information server 10 transmits the traveler information to the management server 20 at a predetermined timing (for example, 72 hours before the traveler departs from the destination, at the time of departure, etc.).

The management server 20 records the traveler information received from the traveler information server 10 and the credit list of the travel agency. As shown in FIG. 3, the management server 20 has, for example, a travel agency information database (DB) 21 that records traveler information and a travel agency database (DB) 23 that records a travel agency credit list. ..

The traveler information DB 21 records the information received from the traveler information server 10 for each traveler. That is, the traveler information DB 21 records the traveler information including the authentication information and the reservation information of the traveler acquired at the departure place.

The travel agency credit list recorded in the travel agency database 23 is, for example, a list of travel agencies that have arranged tickets for terrorists, criminals, etc. in the past (hereinafter, also referred to as "black list"). You may. Alternatively, it may be a list of credible travel agencies (hereinafter, also referred to as "white list"), such as being a member of a credible organization such as a travel agency association. The credit list of a travel agency is provided by an administrative agency that controls the entry and exit of travelers, such as the Ministry of Justice. In the travel agency DB 23, for example, as shown in FIG. 4, a travel agency name 23b and the like are recorded in association with a travel agency ID 23a unique to the travel agency. The information recorded in the management server 20 is used by the suspicious person detection device 100.

The information terminal 30, the immigration gate 40, and the immigration terminal 50 are devices installed at the immigration office of the destination. As described with reference to FIG. 2, the guidance terminal 30 is a device for guiding a traveler to the immigration gate 40 or the immigration booth. The immigration gate 40 is a device that performs immigration inspection of travelers. The immigration terminal 50 is installed in the immigration booth and is used by immigration officers. The guidance terminal 30, the immigration gate 40, and the immigration terminal 50 are configured to be able to receive information from the suspicious person detection device 100 via the network 5.

As shown in FIG. 3, the suspicious person detection device 100 includes a collation unit 110, a determination unit 120, a determination unit 130, and a storage unit 140.

As described in FIG. 1, the collation unit 110 collates the traveler's authentication information acquired at the departure point with the traveler's authentication information acquired at the destination. The authentication information includes passport information, biometric information, and the like. When passport information is used as authentication information, information that can identify the traveler, such as a passport number, is used. When the biometric information of the traveler acquired at the place of departure is a facial image, a facial photograph of a passport may be used. When biometric information is used as authentication information, biometric information that can be collated with the biometric information of the traveler acquired at the departure point is acquired at the destination.

At the destination, for example, an authentication information acquisition device will be installed in the passageway until the traveler arrives at the immigration checkpoint. Alternatively, the guidance terminal 30 installed at the immigration checkpoint at the destination may also retain the function of the authentication information acquisition device. Specifically, the authentication information acquisition device is a passport reader that acquires passport information from a passport, an imaging device that acquires a face image, and the like. If a face image is used as the authentication information, it is possible to acquire the face image of the traveler by the image pickup device while the traveler is moving, for example, from getting off the airplane to arriving at the immigration checkpoint. As a result, the traveler does not have to present the information by himself / herself, and the suspicious person detection device 100 finishes the suspicious person detection process by the time the traveler arrives at the immigration checkpoint, and the immigration examination of the traveler can proceed smoothly.

The collation unit 110 collates the traveler's authentication information acquired by the authentication information acquisition device with the traveler's authentication information acquired at the departure point, and travels recorded in the traveler information DB 21 of the management server 20. Identify the relevant person from the person information. That is, the collation unit 110 collates the passport number or the biometric information, and identifies a person who matches the traveler's authentication information acquired at the destination from the traveler information DB 21. The collation unit 110 outputs the collation result to the determination unit 120.

The determination unit 120 determines whether or not the traveler is a suspicious person based on the travel agency information included in the travel agency reservation information associated with the collated authentication information. The determination unit 120 identifies the travel agency information associated with the traveler's authentication information in the traveler information DB 21 from the collation result input from the collation unit 110. Then, the determination unit 120 determines whether or not the travel agency used by the traveler is listed in the credit list of the travel agency based on the specified travel agency information. For example, the determination unit 120 acquires the travel agency ID recorded in the traveler information DB 21, and determines whether or not the travel agency ID is listed in the credit list recorded in the travel agency DB 23. ..

For example, when the travel agency's credit list is a blacklist, the determination unit 120 determines that the traveler is a suspicious person if the travel agency used by the traveler is listed on the travel agency's credit list. Judge that the possibility is high. On the other hand, if the travel agency used by the traveler is not listed in the travel agency's credit list, the determination unit 120 determines that the traveler is unlikely to be a suspicious person. Further, for example, when the credit list of the travel agency is a white list, the determination unit 120 determines that the traveler if the travel agency used by the traveler is listed in the credit list of the travel agency. Judge that the possibility of being a suspicious person is low. On the other hand, if the travel agency used by the traveler is not listed in the travel agency's credit list, the determination unit 120 determines that the traveler is likely to be a suspicious person.

Both the blacklist and the whitelist may be used as the credit list of the travel agency. For example, a new travel agency is likely not on either the blacklist or whitelist. Therefore, it is possible that a suspicious person such as a terrorist may use a new travel agency. In this case, the determination unit 120 may determine that a traveler using a travel agency not listed in either the blacklist or the white list is likely to be a suspicious person.

The determination unit 120 may output the determination result together with the traveler's authentication information to the immigration gate 40 or the immigration terminal 50 via the network 5. The immigration examiner who uses the immigration gate 40 and the immigration terminal 50, which receives the determination result from the determination unit 120, can determine whether it is necessary to strictly carry out the immigration examination based on the determination result. Alternatively, the determination unit 120 may output the determination result to the determination unit 130.

The decision unit 130 determines the immigration gate 40 or the immigration booth that examines travelers based on the determination result by the determination unit 120. If there is a high possibility that the traveler is a suspicious person as a result of the judgment by the judgment unit 120, the decision unit 130 will handle the immigration examination by a manned immigration gate or a veteran immigration examiner with long experience in immigration examination. Decide to guide you to the booth. On the other hand, if the traveler is unlikely to be a suspicious person, the decision-making department 130 does not need to carry out strict immigration inspection, so an immigration gate for automatic examination or an inexperienced immigration examiner will handle it. You may be guided to the immigration booth.

The determination unit 130 outputs the determined result to the guidance terminal 30 via the network 5. The information terminal 30 guides the traveler to the immigration gate 40 or the immigration booth determined by the decision-making unit 130.

The storage unit 140 stores various information required in the processing performed by the suspicious person detection device 100. The storage unit 140 stores, for example, information about the immigration gate 40 and the immigration booth where the immigration examiner conducts immigration. Specifically, the memory unit 140 records a manned immigration gate that can strictly carry out immigration, an immigration booth where a veteran immigration examiner conducts immigration, and an immigration terminal. doing. This information can be updated at any time. The information recorded in the storage unit 140 can be referred to by each functional unit constituting the suspicious person detection device 100.

[3. Suspicious person detection method]
Hereinafter, the suspicious person detection method according to the present embodiment will be described with reference to FIGS. 5 to 7. 5 to 7 are flowcharts showing an example of the suspicious person detection method according to the present embodiment. The suspicious person detection method according to the present embodiment is implemented by operating the suspicious person detection device 100.

[3-1. Suspicious person detection processing based on the credit of the travel agency]
FIG. 5 shows a suspicious person detection process based on the credit of a travel agency. In FIG. 5, as an example, a suspicious person detection process using a blacklist of a travel agency that describes a travel agency that has arranged a ticket for a terrorist, a criminal, or the like in the past will be described. Blacklisted travel agencies may repeatedly arrange tickets for such persons. The suspicious person detection device 100 according to the present embodiment identifies a person who is likely to be a suspicious person based on the reservation information including the travel agency information used by the traveler.

(S100: Acquisition of traveler information and travel agency credit list)
Specifically, as shown in FIG. 5, the travel agent information and the credit list of the travel agency are recorded in advance on the management server 20 (S100). The management server 20 records the traveler information received from the traveler information server 10, and also records the credit list of the travel agency provided by the Ministry of Foreign Affairs and the like. This information is obtained before the traveler arrives at the destination.

(S110: Authentication information acquisition)
Then, the traveler's authentication information is acquired at the destination (S110). The authentication information is, for example, passport information, biometric information, etc., and is acquired by an authentication information acquisition device installed at the destination. The traveler's authentication information acquired by the authentication information acquisition device is output to the collation unit 110.

(S120, S130: Verification of authentication information)
When the traveler's authentication information is acquired in step S110, the collating unit 110 collates the authentication information and identifies the corresponding person from the traveler information recorded in the traveler information DB 21 of the management server 20 ( S120). At this time, as a result of collating the authentication information of the traveler, if the person whose authentication information matches cannot be identified from the traveler information DB 21, the determination unit 120 determines the collation result with the guidance terminal 30 and the immigration gate 40. Alternatively, it may be output to the immigration terminal 50 (S130). For the traveler, it may be judged that the traveler is likely to be a suspicious person, and strict immigration inspection may be carried out.

(S140-S160: Credit confirmation of travel agency)
On the other hand, when a person whose authentication information of the traveler matches is specified from the traveler information DB 21 in step S120, the determination unit 120 executes the credit confirmation process of the travel agency (S140). That is, the determination unit 120 determines from the travel agency information recorded in the traveler information whether or not the travel agency used by the traveler is listed in the travel agency's credit list.

If the travel agency used by the traveler is listed in the travel agency's credit list, the determination unit 120 determines that the traveler is likely to be a suspicious person (S150). On the other hand, if the travel agency used by the traveler is not listed in the travel agency's credit list, the determination unit 120 determines that the traveler is unlikely to be a suspicious person (S160).

(S170: Judgment result output)
After that, the determination unit 120 outputs the determination result of step S150 or S160 together with the traveler's authentication information to the immigration gate 40 or the immigration terminal 50 via the network 5 (S170). The immigration examiner who uses the immigration gate 40 and the immigration terminal 50, which receives the determination result from the determination unit 120, can determine whether it is necessary to strictly carry out the immigration examination based on the determination result.

Alternatively, the determination unit 120 may output the determination result of step S150 or S160 to the determination unit 130. The decision unit 130 determines the immigration gate 40 or the immigration booth for examining travelers based on the determination result by the determination unit 120. Then, the determination unit 130 outputs the determined result to the guidance terminal 30 via the network 5. The information terminal 30 guides the traveler to the immigration gate 40 or the immigration booth determined by the decision-making unit 130.

In this way, it is possible to determine whether or not the traveler is a suspicious person based on the credit of the travel agency. In the example of FIG. 5, the suspicious person detection process was performed using the black list of the travel agency, but the suspicious person detection process was performed using the white list of the travel agency as the credit list of the travel agency. You may. In this case, if it is determined in step S140 that the travel agency used by the traveler is listed in the travel agency's credit list, the determination unit 120 may indicate that the traveler is a suspicious person. It is judged that the sex is low. On the other hand, if the travel agency used by the traveler is not listed in the travel agency's credit list, the determination unit 120 determines that the traveler is likely to be a suspicious person.

Also, both the blacklist and the whitelist may be used as the credit list of the travel agency. In this case, the determination unit 120 may determine that a traveler using a travel agency not listed in either the blacklist or the white list is likely to be a suspicious person.

[3-2. Suspicious person detection processing based on companion information]
In the suspicious person detection device 100 according to the present embodiment, the traveler is a suspicious person based on, for example, information on the companion of the traveler (also referred to as "accompanying information") in addition to the credit of the travel agency. It is also possible to determine whether or not. If there is a person who is judged to be a suspicious person in the companion of the traveler, it is highly likely that the person who acts with the suspicious person is also a suspicious person. Therefore, when the traveler has a companion, the suspicious person detection device 100 may determine whether or not the traveler is a suspicious person based on the companion information. Hereinafter, the suspicious person detection process based on the companion information will be described with reference to FIG.

(S200: Acquisition of traveler information)
First, as shown in FIG. 6, traveler information is recorded in advance on the management server 20 (S200). The process of step S200 may be performed in the same manner as in step S100 of FIG. The traveler information is recorded in the management server 20 before the traveler arrives at the destination.

(S210: Authentication information acquisition)
Then, the traveler's authentication information is acquired at the destination (S210). The process of step S210 may be performed in the same manner as in step S110 of FIG. The traveler's authentication information acquired by the authentication information acquisition device is output to the collation unit 110.

(S220, S230: Verification of authentication information)
When the traveler's authentication information is acquired in step S210, the collating unit 110 collates the authentication information and identifies the corresponding person from the traveler information recorded in the traveler information DB 21 of the management server 20 ( S220). At this time, as a result of collating the authentication information of the traveler, if the person whose authentication information matches cannot be identified from the traveler information DB 21, the determination unit 120 determines the collation result with the guidance terminal 30 and the immigration gate 40. Alternatively, it may be output to the immigration terminal 50 (S230). For the traveler, it may be judged that the traveler is likely to be a suspicious person, and strict immigration inspection may be carried out. The processing of steps S220 and S230 may be performed in the same manner as in steps S120 and 130 of FIG.

(S235: Confirmation of accompanying person)
On the other hand, when a person whose authentication information of the traveler matches is specified from the traveler information DB 21 in step S220, the determination unit 120 confirms the presence or absence of a companion (S235). For example, information about a companion who has booked a ticket or the like with the traveler is recorded in the PNR, such as when the traveler arranges the airline ticket or the like of the companion together. Therefore, the determination unit 120 can confirm that the traveler has a companion if the companion information is described in the traveler information recorded in the traveler information DB 21 of the management server 20. If it is determined in step S235 that there is no companion, the determination unit 120 ends the process.

(S240-S260: Confirmation of companion's credit)
On the other hand, when it is confirmed in step S235 that the traveler has a companion, the determination unit 120 executes the credit confirmation process of the companion (S240). Upon acquiring the companion information, the determination unit 120 determines whether or not the companion is a suspicious person. Whether or not the companion is a suspicious person may be determined by a determination process of whether or not the traveler is a suspicious person as described with reference to FIG. Alternatively, the determination unit 120 may determine whether or not the companion is a suspicious person based on a list of terrorists, criminals, and the like provided in advance. Such a list may be recorded in the management server 20. When the determination unit 120 determines that the companion is a suspicious person, the determination unit 120 determines that the traveler who acts with the companion is also likely to be a suspicious person (S250). On the other hand, if the determination unit 120 determines that the companion is not a suspicious person, it determines that the traveler is unlikely to be a suspicious person (S260).

(S270: Judgment result output)
After that, the determination unit 120 outputs the determination result of step S250 or S260 together with the traveler's authentication information to the immigration gate 40 or the immigration terminal 50 via the network 5 (S270). The immigration examiner who uses the immigration gate 40 and the immigration terminal 50, which receives the determination result from the determination unit 120, can determine whether it is necessary to strictly carry out the immigration examination based on the determination result.

Alternatively, the determination unit 120 may output the determination result of step S250 or S260 to the determination unit 130. The decision unit 130 determines the immigration gate 40 or the immigration booth for examining travelers based on the determination result by the determination unit 120. Then, the determination unit 130 outputs the determined result to the guidance terminal 30 via the network 5. The information terminal 30 guides the traveler to the immigration gate 40 or the immigration booth determined by the decision-making unit 130. The process of step S270 may be performed in the same manner as in step S170 of FIG.

In this way, when a traveler has a companion, it can be determined whether or not the traveler is a suspicious person based on the companion's credit.

[3-3. Suspicious person detection processing based on the traveler information of a specific traveler]
The suspicious person detection device 100 according to the present embodiment can further determine whether or not the traveler is a suspicious person based on, for example, the traveler information of the specific traveler. Here, the specific traveler refers to a person who is not a companion of the traveler but is a suspicious person such as a terrorist or a criminal. Even if the traveler does not have acquaintance with the specific traveler, he / she may be sitting next to each other in the means of transportation such as an airplane, or the movement route from the departure point to the destination may be the same. It is conceivable to have common traveler information. Therefore, the suspicious person detection device 100 is a suspicious person based on whether or not the traveler who has moved by the same means of transportation as the specific traveler has the same traveler information as the specific traveler. It may be determined whether or not. Hereinafter, the suspicious person detection process based on the traveler information of the specific traveler will be described with reference to FIG. 7.

(S300: Acquisition of traveler information)
First, as shown in FIG. 7, traveler information is recorded in advance on the management server 20 (S300). The process of step S300 may be performed in the same manner as in step S100 of FIG. The traveler information is recorded in the management server 20 before the traveler arrives at the destination.

(S310: Authentication information acquisition)
Then, the traveler's authentication information is acquired at the destination (S310). The process of step S310 may be performed in the same manner as in step S110 of FIG. The traveler's authentication information acquired by the authentication information acquisition device is output to the collation unit 110.

(S320, S330: Verification of authentication information)
When the traveler's authentication information is acquired in step S310, the collating unit 110 collates the authentication information and identifies the corresponding person from the traveler information recorded in the traveler information DB 21 of the management server 20 ( S320). At this time, as a result of collating the authentication information of the traveler, if the person whose authentication information matches cannot be identified from the traveler information DB 21, the determination unit 120 determines the collation result with the guidance terminal 30 and the immigration gate 40. Alternatively, it may be output to the immigration terminal 50 (S330). For the traveler, it may be judged that the traveler is likely to be a suspicious person, and strict immigration inspection may be carried out. The processing of steps S320 and S330 may be performed in the same manner as in steps S120 and 130 of FIG.

(S335: Confirmation of the presence or absence of specific travelers)
On the other hand, when a person whose authentication information of the traveler matches is specified from the traveler information DB 21 in step S320, the determination unit 120 confirms whether or not the specific traveler exists in the person who has moved by the same means of transportation. (S335).

The determination unit 120 may set a person using a travel agency with low credibility, which is specified by the determination process of whether or not the traveler is a suspicious person described in FIG. 5, as the specific traveler. Alternatively, the determination unit 120 may identify a specific traveler based on a list of terrorists, criminals, etc. provided in advance. Alternatively, a person whose departure point or transit point is a place designated as a dangerous area may be a specific traveler. Such a list may be recorded in the management server 20. If it is determined in step S335 that the specific traveler does not exist, the determination unit 120 ends the process.

(S340-S360: Confirmation of commonality with specific travelers)
On the other hand, when it is confirmed in step S335 that the specific traveler exists in the person who has moved by the same means of transportation, the determination unit 120 shares the traveler information of the traveler with the traveler information of the specific traveler. Whether or not it is determined (S340). The determination of the commonality of the traveler information may be carried out based on whether or not the items specified in advance in the traveler information match or satisfy a predetermined condition. The items to be specified include, for example, the departure point and destination (if there is a waypoint), the flight number of the means of transportation, the departure date, the seat information, the travel agency used, and the like. For example, in the determination unit 120, when the departure place, the waypoint, the destination, the flight number of the means of transportation, and the departure date are the same, and the specific traveler is seated at any of the front, rear, left, and right positions, the traveler It may be determined that the information is common.

When a specific traveler exists in a person who uses the same means of transportation as the traveler, the determination unit 120 determines whether or not the traveler information of the traveler is common with the traveler information of the specific traveler. If the determination unit determines that the traveler information of the traveler is common to the traveler information of the specific traveler, it determines that the traveler is also likely to be a suspicious person (S350). On the other hand, if the determination unit 120 determines that the traveler information of the traveler is not common to the traveler information of the specific traveler, it determines that the possibility that the traveler is a suspicious person is low (S360). As a result, for example, a person who is not accompanied by a traveler because the reservation number is different from that of the traveler, but who is sitting in either the front, back, left, or right position is using a travel agency with low creditworthiness, or the place of departure. Alternatively, if the transit point is a designated dangerous area, it will be determined that the traveler is likely to be a suspicious person.

(S370: Judgment result output)
After that, the determination unit 120 outputs the determination result of step S350 or S360 together with the traveler's authentication information to the immigration gate 40 or the immigration terminal 50 via the network 5 (S370). The immigration examiner who uses the immigration gate 40 and the immigration terminal 50, which receives the determination result from the determination unit 120, can determine whether it is necessary to strictly carry out the immigration examination based on the determination result.

Alternatively, the determination unit 120 may output the determination result of step S350 or S360 to the determination unit 130. The decision unit 130 determines the immigration gate 40 or the immigration booth for examining travelers based on the determination result by the determination unit 120. Then, the determination unit 130 outputs the determined result to the guidance terminal 30 via the network 5. The information terminal 30 guides the traveler to the immigration gate 40 or the immigration booth determined by the decision-making unit 130. The process of step S370 may be performed in the same manner as in step S170 of FIG.

In this way, if a specific traveler exists in a person who uses the same means of transportation as the traveler, whether or not the traveler is a suspicious person based on the commonality with the traveler information of the specific traveler. Can be determined.
