Description

Method and device for confirming passenger boarding in UAM environment

[0001] The present disclosure relates to a method and device for verifying passenger boarding in an UAM environment. More specifically, the present disclosure relates to a method and device for automatically verifying whether a passenger who has reserved a UAM aircraft is seated in the reserved seat of the aircraft by applying multi-factor authentication (MFA) and / or an encryption algorithm, and for preventing unauthorized boarding of the reserved seat by a third party by stealing the passenger's device or token.

[0002] The content described below merely provides background information related to the present embodiment and does not constitute prior art.

[0003] Urban Air Mobility (UAM) is a three-dimensional urban air transport system that connects ground and air, a next-generation transportation system capable of transporting people and cargo in the skies above cities. As the UAM market expands, urban air mobility will provide the public with a new means of transportation, relieving traffic congestion. Furthermore, it will open up the possibility of repurposing the urban space currently occupied by numerous roads, parking lots, and other facilities that enable ground transportation.

[0004] Once UAM is commercialized, passengers will be required to make advance reservations to use it. Therefore, a method is needed to verify that each passenger has boarded their assigned seat on the aircraft. Furthermore, a method is needed to prevent third parties from using the passenger's information to board the seat. For example, a method is needed to prevent third parties from stealing a user's token or obtaining a user's smartphone to board the aircraft.

[0005] However, prior art technologies only provide information on passenger presence, check boarding and disembarkation for fare collection, or authenticate vehicle and passenger when calling a self-driving car. These technologies do not disclose methods for verifying that each passenger is seated in their assigned seat or verifying that the passenger in the seat is actually the one who reserved the seat.

[0006]

[0007] The main purpose of the present disclosure is to provide a method and device that can automatically check whether a passenger boarding a UAM aircraft has boarded a designated seat.

[0008] In addition, the present disclosure primarily aims to provide a method and device for verifying whether a passenger boarding a UAM aircraft has boarded a reserved seat using a cryptographic method.

The flight information server (500) may transmit flight information to the aircraft (400) (S520). The flight information may include flight number, platform, departure time, seat information, etc.

[0061] The aircraft (400) can receive flight information and store the flight information (S530). The aircraft (400) can receive flight information and set seat numbers for each seat based on the flight information (S530). The seat numbers for the seats included in the aircraft (400) can be set when the aircraft (400) is produced or can be set later. Therefore, the aircraft (400) has information about the seat numbers for the seats included in the aircraft (400).

[0062] An aircraft (400) may request passenger information from a reservation server (300) (S540). The aircraft (400) may request passenger information from the reservation server (300) by transmitting passenger information request data to the reservation server (300).

[0065] The user tags the user terminal (200) used for reservation to the boarding confirmation device (100) (S605). By tagging the user terminal (200) to the boarding confirmation device (100), the user terminal can send a signal to the boarding confirmation device (100) using short-range communication to initiate the boarding confirmation process.

[0066] In response to the signal received from the user terminal (200), the boarding confirmation device (100) sends a token (C) combined with the electronic signature of the reservation server (300) to the user terminal (200). T ) while requesting your own certificate (Cert SD ) can be transmitted (S610).

[0067] The user terminal (200) has a certificate (Cert) of the boarding confirmation device (100). SD ) is verified (S615). If the verification is successful, the user terminal (200) can receive identification information (password, fingerprint, etc.) from the user. The identification information may be information including one or more of the user's password, biometric information, card information, and certificate. The user terminal (200) inputs the public key (Pub) of the boarding confirmation device (100) as in mathematical expression 2. SD ) can encrypt the user's identification information (S620).

[0068] [Equation 2]

[0069] C C = E(Identification Information, Pub SD )

[0070] The user terminal (200) transmits an encrypted token (C) combined with an electronic signature to the boarding confirmation device (100). T ), encrypted identity information (C C ) and your own certificate (Cert P ) can be transmitted (S625).

[0071] The boarding confirmation device (100) is a certificate (Cert) of the user terminal (200). P ) and cryptographic tokens (C T ) can verify the electronic signature of the reservation server (300) combined with the boarding confirmation device (100) using an encrypted token (C T) can be used to separate the electronic signature of the reservation server (300) and verify the electronic signature of the reservation server (300). The public key (or certificate) of the reservation server (300) for the boarding confirmation device (100) to verify the electronic signature of the reservation server (300) is injected when the boarding confirmation device (100) is produced or injected after release. The boarding confirmation device (100) can verify the electronic signature of the reservation server (300) using the public key (or certificate) of the reservation server (300) stored in the memory.

The boarding confirmation device (100) can obtain a symmetric key (K) using the user's identification information. The boarding confirmation device (100) uses the symmetric key (K) to obtain an encrypted token (C) containing reservation information. T ) can be decrypted (S640)

[0073] Mathematical expression 3 shows that the boarding confirmation device (100) obtains a symmetric key (K) using the user's identification information, and uses the symmetric key (K) to obtain an encrypted token (C). T ) is a formula to represent the process of decrypting.

[0074] [Equation 3]

[0075] Identity Verification Information = D(C C , Prv SD )

[0076] K = KDF(Identity Derivative)
