The suspicious person detection device 100 according to the present embodiment determines whether or not there is a high possibility that a traveler attempting to enter Japan is a suspicious person based on the travel agency used by the traveler to arrange a flight ticket. . For example, a travel agency that has arranged airline tickets for terrorists, criminals, etc. in the past may repeatedly arrange airline tickets for such individuals. 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 that includes information about the travel agency used by the traveler (also referred to as "travel agency information"). do.

More specifically, the suspicious person detection device 100 includes a verification section 110 and a determination section 120, as shown in FIG. The matching unit 110 matches the traveler's authentication information obtained at the departure point with the traveler's authentication information obtained at the destination. The determining unit 120 determines whether the traveler is a suspicious person based on travel agency information included in the traveler's reservation information associated with the verified authentication information.

Thereby, the suspicious person detection device 100 can determine whether there is a high possibility that the traveler is a suspicious person before entering the country. As a result, it becomes possible to take measures such as conducting strict immigration inspections for people who are likely to be suspicious, thereby preventing suspicious people from entering the country. Furthermore, it can be determined that there is little need to strictly conduct immigration inspections on persons who are unlikely to be suspicious. Therefore, it is possible to judge whether or not immigration inspection should be carried out strictly depending on the possibility of a suspicious person, and it is also possible to carry out immigration inspection efficiently.

[2. Device configuration]
The configuration and functions of the suspicious person detection device 100 according to this embodiment will be explained based on FIGS. 2 to 4. FIG. 2 is an explanatory diagram showing an overview 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 trust list recorded in the travel agency DB 23.

As shown in FIG. 2, the suspicious person detection device 100 according to the present embodiment detects terrorists and terrorists before entering the country at the destination, for example, with respect to a traveler heading from a departure point to a destination using a means of transportation such as an airplane. Determine whether the person is likely to be a criminal such as a criminal. Therefore, at the place of departure, traveler information of the traveler is acquired and recorded in the management server 20. The management server 20 also records a trust list of travel agencies. The travel agency trust list is a list of travel agencies that have arranged airline tickets for terrorists, criminals, etc. in the past. The suspicious person detection device 100 detects the possibility that the traveler is a suspicious person based on various information from the management server 20 connected via the network 5 and the traveler's authentication information obtained 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 conducting immigration inspection. If it is determined that there is a high possibility that the traveler is a suspicious person, immigration inspection must be carried out strictly. It is preferable that a government official guide you to the corresponding immigration booth. Additionally, if it is determined that there is a low possibility that the traveler is a suspicious person, there is little need to carry out strict immigration inspection, and the traveler should be sent to an automated immigration inspection gate or to an inexperienced immigration inspector. may direct you to the corresponding immigration booth.

In this way, based on the determination result by the suspicious person detection device 100, it becomes possible to sort the traveler to an appropriate immigration gate or immigration booth depending on the possibility that the person is a suspicious person. The sorting of travelers may be performed, for example, by guiding the travelers using a guidance terminal 30 installed at the immigration inspection area, as shown in FIG. Alternatively, the determination result of the suspicious person detection device 100 may be notified to the immigration inspection gates 41 to 43, and the strictness of the immigration inspection may be changed depending on the possibility that the person is a suspicious person. It may also be possible to refuse immigration inspection to persons with high scores.

By using the suspicious person detection device 100, it is possible to prevent suspicious persons from entering the country, and it is also possible to judge whether or not immigration inspection should be strictly carried out depending on the possibility of a suspicious person, increasing efficiency. It will also be possible to conduct immigration inspections more frequently.

FIG. 3 shows a configuration of a suspicious person detection system constructed using the suspicious person detection device 100 according to the present embodiment, and an example of the configuration of the suspicious person detection device 100. In the suspicious person detection system, as shown in FIG. Connected and configured.

The traveler information server 10 is a server managed by an airline company or the like, and records traveler information of travelers acquired at the place of departure. The traveler information server 10 records, for example, the traveler's biometric information, name, information on the travel agency that arranged the airline ticket, etc., acquired at the time of check-in at the airport of departure. The biological information of the traveler is, for example, information about the face, fingerprints, irises, veins, etc., and can be obtained from the traveler, for example, at or before check-in. Note that the biological information is acquired as an image or video by, for example, an imaging device, and is held as the acquired image or video, or a feature amount extracted from the acquired image or video. The traveler's name, travel agent information, etc. can be obtained from API (Advance Passenger Information) and PNR (Passenger Name Record).

The API includes, for example, information such as name, nationality, date of birth, passport number, place of departure, final destination, and gender. PNR includes, for example, information about the person who made the reservation (name, nationality, date of birth, etc.), information about the details of the reservation (travel agency that made the reservation, date of reservation, ticket number, date of issue, etc.), This information includes information regarding the reservation person's personal belongings (number of personal items, weight, etc.), information regarding the procedure for the reservation person to board the aircraft (time of boarding procedure, etc.).

The traveler information server 10 transmits 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 a trust list of travel agencies. As shown in FIG. 3, the management server 20 includes, for example, a traveler information database (DB) 21 that records traveler information and a travel agency database (DB) 23 that records a trust list of travel agencies. .

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

The trust list of travel agencies recorded in the travel agency database 23 is, for example, a list of travel agencies that have arranged airline tickets for terrorists, criminals, etc. in the past (hereinafter also referred to as a "black list"). You can. Alternatively, it may be a list of trusted travel agencies (hereinafter also referred to as a "white list"), such as members of a trusted organization such as a travel agency association. A trusted list of travel agencies is provided by, for example, an administrative agency that manages 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 guidance terminal 30, the immigration inspection gate 40, and the immigration inspection terminal 50 are devices installed at the immigration inspection area of the destination. As explained with reference to FIG. 2, the guide terminal 30 is a device for guiding travelers to the immigration gate 40 or the immigration booth. The immigration inspection gate 40 is a device that conducts immigration inspection for travelers. The immigration terminal 50 is installed in an immigration booth and is used by an immigration inspector. The guide 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 section 110, a determination section 120, a determination section 130, and a storage section 140.

As explained in FIG. 1, the matching unit 110 matches 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, etc. When using passport information as authentication information, information that can identify the traveler, such as a passport number, is used. If the traveler's biometric information acquired at the place of departure is a facial image, a passport photo may be used. When biometric information is used as authentication information, biometric information that can be compared with the traveler's biometric information obtained at the departure point is obtained at the destination.

At the destination, an authentication information acquisition device is installed, for example, in the passageway that travelers take until they arrive at the immigration checkpoint. Alternatively, the guidance terminal 30 installed at the immigration checkpoint at the destination may also have the function of an 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 facial image, or the like. If a facial image is used as authentication information, it is possible to acquire a facial image of a traveler using an imaging device while the traveler is moving, for example, from getting off an airplane to arriving at an immigration inspection area. Thereby, the traveler does not have to present any information himself/herself, and the suspicious person detection device 100 finishes the suspicious person detection process by the time the traveler arrives at the immigration inspection area, allowing the traveler's immigration inspection to 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 place of departure, and checks the travel information recorded in the traveler information DB 21 of the management server 20. Identify the relevant person from personal information. That is, the collation unit 110 collates the passport number or biometric information, and identifies from the traveler information DB 21 a person whose authentication information of the traveler obtained at the destination matches. The matching unit 110 outputs the matching result to the determining unit 120.

The determining unit 120 determines whether the traveler is a suspicious person based on travel agency information included in the traveler's reservation information associated with the verified authentication information. The determination unit 120 identifies travel agency information associated with the traveler's authentication information in the traveler information DB 21 from the verification results input from the verification unit 110. Then, the determination unit 120 determines whether the travel agency used by the traveler is listed in the travel agency trust list based on the identified travel agency information. For example, the determination unit 120 acquires the travel agency ID recorded in the traveler information DB 21 and determines whether the travel agency ID is listed in the trust list recorded in the travel agency DB 23. .

For example, if the travel agency trust 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 in the travel agency trust list. It is determined that the possibility is high. On the other hand, if the travel agency used by the traveler is not listed in the travel agency trust list, the determination unit 120 determines that the traveler is unlikely to be a suspicious person. Further, for example, if the travel agency trust list is a white list, the determination unit 120 determines that if the travel agency used by the traveler is listed in the travel agency trust list, the travel agent It is determined that there is a low possibility that the person is a suspicious person. On the other hand, if the travel agency used by the traveler is not listed in the travel agency trust list, the determination unit 120 determines that there is a high possibility that the traveler is a suspicious person.

Note that both a blacklist and a whitelist may be used as the travel agency trust list. For example, a new travel agency is likely not on either a blacklist or a whitelist. Therefore, there is a possibility that suspicious persons such as terrorists may use new travel agencies. In this case, the determination unit 120 may determine that a traveler who used a travel agency that is not listed on either the blacklist or the whitelist is likely to be a suspicious person.

The determination unit 120 may output the determination result to the immigration gate 40 or the immigration terminal 50 via the network 5 together with the traveler's authentication information. An immigration inspector using the immigration gate 40 and immigration terminal 50 that has received the determination result from the determination unit 120 can determine whether it is necessary to strictly conduct the immigration inspection based on the determination result. Alternatively, the determination unit 120 may output the determination result to the determination unit 130.

The determining unit 130 determines the immigration gate 40 or immigration booth where the traveler will be examined based on the determination result by the determining unit 120. If the decision made by the determining unit 120 indicates that there is a high possibility that the traveler is a suspicious person, the determining unit 130 determines whether the traveler is likely to be a suspicious person or not. Decide to show them to the booth. On the other hand, the decision unit 130 determines that if there is a low possibility that the traveler is a suspicious person, there is little need to strictly carry out immigration inspection, and therefore an automatic immigration inspection gate or an inexperienced immigration inspector will handle the case. You may also be directed to the immigration booth where you will be held.

The determining unit 130 outputs the determined result to the guide terminal 30 via the network 5. The guide terminal 30 guides the traveler to the immigration gate 40 or immigration booth determined by the determining unit 130.

The storage unit 140 stores various types of information required in the processing performed by the suspicious person detection device 100. The storage unit 140 stores, for example, information regarding the immigration gate 40 and the immigration booth where an immigration inspector conducts the immigration examination. Specifically, the storage unit 140 records manned immigration gates where immigration inspections can be strictly conducted, immigration booths where experienced immigration inspectors conduct immigration inspections, and immigration inspection terminals. are doing. This information can be updated at any timing. The information recorded in the storage unit 140 can be referenced by each functional unit that constitutes the suspicious person detection device 100.

[3. Suspicious person detection method]
The suspicious person detection method according to this embodiment will be described below based on 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 this embodiment is implemented by operating the suspicious person detection device 100.

[3-1. Suspicious person detection processing based on the trust of the travel agency]
FIG. 5 shows suspicious person detection processing based on the trust of the travel agency. In FIG. 5, as an example, a suspicious person detection process will be described using a blacklist of travel agencies that lists travel agencies that have arranged airline tickets for terrorists, criminals, etc. in the past. A blacklisted travel agent may repeatedly arrange flights 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 on the travel agency used by the traveler.

(S100: Obtain traveler information and travel agency trust list)
Specifically, as shown in FIG. 5, traveler information and a trust list of travel agencies are recorded in advance in the management server 20 (S100). The management server 20 records the traveler information received from the traveler information server 10, as well as a trusted list of travel agencies provided by the Ministry of Foreign Affairs or the like. This information is obtained before the traveler arrives at his or her destination.

(S110: Authentication information acquisition)
Next, 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 verification unit 110.

(S120, S130: Verification of authentication information)
When the traveler's authentication information is acquired in step S110, the collation 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 comparing the traveler's authentication information, if it is not possible to identify a person whose authentication information matches from the traveler information DB 21, the determination unit 120 transmits the comparison results to the information terminal 30, the immigration gate 40, etc. Alternatively, the information may be output to the immigration terminal 50 (S130). It may be determined that there is a high possibility that the traveler is a suspicious person, and strict immigration inspections may be conducted for the traveler.

(S140-S160: Travel agency trust confirmation)
On the other hand, when a person whose authentication information matches the traveler is identified from the traveler information DB 21 in step S120, the determination unit 120 executes a credit confirmation process for the travel agency (S140). That is, the determination unit 120 determines whether the travel agency used by the traveler is listed in the travel agency trust list, based on the travel agency information recorded in the traveler information.

If the travel agency used by the traveler is listed in the travel agency trust 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 trust list, the determination unit 120 determines that the possibility that the traveler is a suspicious person is low (S160).

(S170: Judgment result output)
Thereafter, 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). An immigration inspector using the immigration gate 40 and immigration terminal 50 that has received the determination result from the determination unit 120 can determine whether it is necessary to strictly conduct the immigration inspection 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 determining unit 130 determines the immigration gate 40 or immigration booth where the traveler will be examined based on the determination result by the determining unit 120. Then, the determining unit 130 outputs the determined result to the guide terminal 30 via the network 5. The guide terminal 30 guides the traveler to the immigration gate 40 or immigration booth determined by the determining unit 130.

In this way, it is possible to determine whether the traveler is a suspicious person based on the trust of the travel agency. In the example shown in Figure 5, the suspicious person detection process was performed using the travel agency's blacklist, but the suspicious person detection process was performed using the travel agency's whitelist as the travel agency's trust list. You can. In this case, if it is determined in step S140 that the travel agency used by the traveler is listed on the travel agency trust list, the determination unit 120 determines that the traveler may be a suspicious person. It is determined that the quality is low. On the other hand, if the travel agency used by the traveler is not listed in the travel agency trust list, the determination unit 120 determines that the traveler is likely to be a suspicious person.

Further, both a blacklist and a whitelist may be used as the trust list of travel agencies. In this case, the determination unit 120 may determine that a traveler who used a travel agency that is not listed on either the blacklist or the whitelist is likely to be a suspicious person.

[3-2. Suspicious person detection processing based on companion information]
The suspicious person detection device 100 according to the present embodiment detects whether the traveler is a suspicious person based on, for example, information regarding the traveler's companions (also referred to as "accompanying information") in addition to the credibility of the travel agency. It is also possible to determine whether or not. If there is a person in the traveler's companion who is judged to be a suspicious person, there is a high possibility that the person traveling with the suspicious person is also a suspicious person. Therefore, if the traveler has a companion, the suspicious person detection device 100 may determine whether the traveler is a suspicious person based on the companion information. Hereinafter, based on FIG. 6, a suspicious person detection process based on companion information will be explained.

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

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

(S220, S230: Verification of authentication information)
When the traveler's authentication information is acquired in step S210, the collation 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 comparing the traveler's authentication information, if it is not possible to identify a person whose authentication information matches from the traveler information DB 21, the determination unit 120 transmits the comparison results to the information terminal 30, the immigration gate 40, etc. Alternatively, the information may be output to the immigration inspection terminal 50 (S230). It may be determined that there is a high possibility that the traveler is a suspicious person, and strict immigration inspections may be conducted for the traveler. The processes in steps S220 and S230 may be performed in the same manner as steps S120 and 130 in FIG.

(S235: Confirm presence of companion)
On the other hand, when a person whose authentication information matches the traveler is identified from the traveler information DB 21 in step S220, the determination unit 120 checks whether there is a companion (S235). For example, when a traveler makes arrangements for a flight ticket, etc. for a companion, information regarding the traveler and a companion for whom a flight ticket, etc., is reserved together is recorded in the PNR. Therefore, the determination unit 120 can confirm that the traveler has a companion if the traveler information recorded in the traveler information DB 21 of the management server 20 includes companion information. If it is determined in step S235 that there is no accompanying person, the determination unit 120 ends the process.

(S240-S260: Confirmation of companion's credibility)
On the other hand, if it is confirmed in step S235 that the traveler has a companion, the determination unit 120 carries out a process of confirming the credibility of the companion (S240). Upon acquiring the accompanying person information, the determining unit 120 determines whether the accompanying person is a suspicious person. Whether or not the accompanying person is a suspicious person may be determined by the process of determining whether or not the traveler is a suspicious person, as explained based on FIG. 5 . Alternatively, the determining unit 120 may determine whether the accompanying person is a suspicious person based on a list of terrorists, criminals, etc. provided in advance. Such a list may be recorded on the management server 20. When determining that the accompanying person is a suspicious person, the determining unit 120 determines that there is a high possibility that the traveler traveling with the accompanying person is also a suspicious person (S250). On the other hand, if the determination unit 120 determines that the accompanying person is not a suspicious person, it determines that the possibility that the traveler is a suspicious person is low (S260).

(S270: Judgment result output)
Thereafter, 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). An immigration inspector using the immigration gate 40 and immigration terminal 50 that has received the determination result from the determination unit 120 can determine whether it is necessary to strictly conduct the immigration inspection 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 determining unit 130 determines the immigration gate 40 or immigration booth where the traveler will be examined based on the determination result by the determining unit 120. Then, the determining unit 130 outputs the determined result to the guide terminal 30 via the network 5. The guide terminal 30 guides the traveler to the immigration gate 40 or immigration booth determined by the determining unit 130. The process in step S270 may be performed in the same manner as step S170 in FIG.

In this way, when a traveler has a companion, it is possible to determine whether the traveler is a suspicious person based on the trust of the traveler.

[3-3. Suspicious person detection processing based on traveler information of specific travelers]
The suspicious person detection device 100 according to the present embodiment can also determine whether or not the traveler is a suspicious person, for example, based on traveler information of a specific traveler. Here, the specific traveler refers to a person who is not a traveler's companion, but is a suspicious person such as a terrorist or criminal. Even if the traveler does not know the specified traveler, there are cases where the specified traveler and the specified traveler are seated next to each other on an airplane or other means of transportation, or the travel route from the departure point to the destination is the same, etc. It is conceivable that the two countries have common traveler information. Therefore, the suspicious person detection device 100 determines whether a traveler who has traveled by the same means of transportation as a specified traveler is a suspicious person based on whether or not the traveler has traveler information common to the specified traveler. It may be determined whether or not. Hereinafter, based on FIG. 7, a suspicious person detection process based on traveler information of a specific traveler will be explained.

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

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

(S320, S330: Verification of authentication information)
When the traveler's authentication information is acquired in step S310, the collation 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 comparing the traveler's authentication information, if it is not possible to identify a person whose authentication information matches from the traveler information DB 21, the determination unit 120 transmits the comparison results to the information terminal 30, the immigration gate 40, etc. Alternatively, the information may be output to the immigration terminal 50 (S330). It may be determined that there is a high possibility that the traveler is a suspicious person, and strict immigration inspections may be conducted for the traveler. The processes in steps S320 and S330 may be performed in the same manner as steps S120 and 130 in FIG.

(S335: Confirmation of presence or absence of specific travelers)
On the other hand, in step S320, when a person whose authentication information of the traveler matches is identified from the traveler information DB 21, the determination unit 120 checks whether a specific traveler exists among the people who traveled by the same means of transportation. (S335).

The determination unit 120 may determine, as the specific traveler, a person who uses a travel agency with low credibility, which is identified by the determination process of whether or not the traveler is a suspicious person as described in FIG. Alternatively, the determination unit 120 may identify the specific traveler based on a list of terrorists, criminals, etc. provided in advance. Alternatively, a person who departs from or transits from a place designated as a dangerous area may be designated as a specific traveler. Such a list may be recorded on 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 specified travelers)
On the other hand, when it is confirmed in step S335 that a specific traveler exists among the persons who traveled by the same means of transportation, the determination unit 120 determines that the traveler information of the traveler is common to the traveler information of the specific traveler. It is determined whether or not (S340). The commonality of the traveler information may be determined based on whether pre-specified items of the traveler information match or satisfy a predetermined condition. Specified items include, for example, the departure point and destination (transit points, if any), the flight number of the means of transportation, the departure date, seat information, and the travel agency used. For example, if the departure point, transit point, destination, flight number of the means of transportation, and departure date are the same, and the specific traveler is sitting in the front, rear, left, or right position, the determination unit 120 determines that the specific traveler It may be determined that the information is common.

If the specific traveler is a person who used the same means of transportation as the traveler, the determining unit 120 determines whether the traveler's traveler information is the same as the traveler information of the specific traveler. If the determination unit determines that the traveler's traveler information 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's traveler information 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 a traveler's companion because their reservation number is different from the traveler's, but who is sitting in front, rear, left, or right, is using a travel agency with low credibility or Alternatively, if the transit point is a place designated as a dangerous area, it will be determined that there is a high possibility that the traveler is a suspicious person.

(S370: Judgment result output)
Thereafter, 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). An immigration inspector using the immigration gate 40 and immigration terminal 50 that has received the determination result from the determination unit 120 can determine whether it is necessary to strictly conduct the immigration inspection 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 determining unit 130 determines the immigration gate 40 or immigration booth where the traveler will be examined based on the determination result by the determining unit 120. Then, the determining unit 130 outputs the determined result to the guide terminal 30 via the network 5. The guide terminal 30 guides the traveler to the immigration gate 40 or immigration booth determined by the determining unit 130. The process in step S370 may be performed in the same manner as step S170 in FIG.

In this way, if there is an identified traveler among the people who used the same means of transportation as the traveler, it is determined whether the traveler is a suspicious person based on the similarity with the traveler information of the identified traveler. can be determined.

Note that the suspicious person detection processes shown in FIGS. 5 to 7 may be performed individually, or may be performed in combination.

The suspicious person detection device 100 and the suspicious person detection method using the same according to the present embodiment have been described above. According to this embodiment, the suspicious person detection device 100 uses the matching unit 110 to match the traveler's authentication information acquired at the departure point with the traveler's authentication information acquired at the destination. Then, the determining unit 120 determines whether the traveler is a suspicious person based on the travel agency information included in the traveler's reservation information associated with the verified authentication information.

Thereby, the suspicious person detection device 100 can determine whether there is a high possibility that the traveler is a suspicious person before entering the country. As a result, it becomes possible to take measures such as conducting strict immigration inspections for people who are likely to be suspicious, thereby preventing suspicious people from entering the country. Furthermore, it can be determined that there is little need to strictly conduct immigration inspections on persons who are unlikely to be suspicious. Therefore, it is possible to judge whether or not immigration inspection should be carried out strictly depending on the possibility of a suspicious person, and it is also possible to carry out immigration inspection efficiently.

In addition, the suspicious person detection device 100 may perform the process of determining whether the traveler is a suspicious person by the determination unit 120 at the place of departure. That is, by acquiring the traveler's authentication information when registering the traveler information at the place of departure, it becomes possible to acquire the reservation information linked to the authentication information. As a result, it becomes possible to specify the travel agency information included in the reservation information, and the suspicious person detection device 100 can determine whether the traveler is a suspicious person based on the travel agency information. can.
