Description

Automatic authentication system for car sharing users {SYSTEM FOR AUTOMATIC AUTHENTICATION OF CAR SHARING USER}

The present invention relates to an automatic vehicle sharing user authentication system. More specifically, when a user approaches a vehicle equipped with a digital tachograph (DTG) terminal, the vehicle and the user terminal automatically perform user authentication, This relates to an automatic authentication system for car sharing users that allows them to receive car sharing services.

When a user travels or goes on a business trip overseas or to another area, when multiple users want to share a vehicle through a car sharing service in the city, or when a company operates vehicles including taxis, trucks, buses, etc. There are many different ways to use vehicles, such as when you want to entrust the task of assigning and managing a vehicle to a driver, when you want to apply new technology, or when you want to use a variety of vehicles with advanced specifications for the period of time you want. It has been changing.

For example, when traveling or going on a business trip overseas or to another region, you visit a local car rental company and rent the car you want for a certain period of time. In this case, it is very inconvenient because you have to visit the rental company in person, sign up for insurance, receive the keys to the vehicle, pick up the vehicle, use it, and return it in person.

Additionally, as new and diverse business models are developed, the need to share vehicles with people who live and work in similar areas or have similar commuting routes is increasing, even in urban areas.

However, if you want to share your vehicle with others, the things that need to be resolved, such as costs, insurance, fuel costs, vehicle maintenance, and handing over and taking over the vehicle keys, are very diverse and complex. This situation becomes an obstacle to the activation of services.

Meanwhile, business operators who rent vehicles, including trucks, buses, cars, taxis, and two-wheeled vehicles, need various management methods for vehicle sharing, but there is no solution yet.

In addition, many domestic and foreign automobile companies are competing to release new cars every year, and users have always had a desire to drive new and good cars. In this case, the newer and better the car, the higher the price of the vehicle that is difficult for the general public to afford, so many users use the vehicle by paying the cost to a leasing company or rental company for a certain period of time through leasing or renting.

Since these vehicle leases are usually handled as long-term contracts of several years, and vehicle rentals are handled as daily contracts, it is very inconvenient for users who want to use the vehicle for a short period of time to use vehicle leasing or vehicle rental.

To solve this problem, recently, users can use shared vehicles for a short period of time when needed, and users can use their smart car without having to visit a specific location and fill out complicated documents to lease or rent a vehicle. Reservations for vehicle use are made using an app installed on a phone, and a service is being introduced that allows for convenient rental in various places in the city.

However, in the car rental service, you can use the car even if you are not the user who made the reservation, as long as you know the specific authentication number provided when making the reservation, so the car can be used indiscriminately, and it can be used by anyone other than the user who made the reservation. There was a problem in that if an accident occurred while driving the vehicle, it was not properly covered by insurance. Additionally, if the authentication number used for the rental service is leaked through hacking, etc., there is a high risk that it will be used not only for vehicle theft but also for crime.

In particular, it is becoming mandatory to install DTG terminals on passenger and cargo transport vehicles such as buses, trucks, and taxis. The DTG terminal records the vehicle's driving record in seconds, including the vehicle's GPS location, speed, presence of braking, distance traveled, engine revolutions per minute (RPM), and amount of impact to the vehicle. In case an accident occurs in the vehicle, is a device that records vehicle driving records in shorter time units (e.g., 0.01 seconds).

The vehicle driving records stored in this way are analyzed as driving data such as speeding, idling, sudden braking, sudden deceleration, and sudden acceleration to correct the driver's driving habits to encourage safe driving or to improve vehicle operation such as saving fuel. It can be used to increase efficiency.

It is stipulated that the vehicle operation records must be submitted on a regular basis to transportation administrative agencies such as the Korea Transportation Safety Authority. Accordingly, by attaching a communication module to the DTG terminal, the vehicle operation records are sent to traffic administrative agencies such as the Korea Transportation Safety Authority through a control server. It is used as a form of submission to administrative agencies.

However, the communication module provided in the DTG terminal is simply used to submit the vehicle operation record to the relevant organizations, and is not utilized for other purposes.

Therefore, in the present invention, when a user approaches a vehicle equipped with a DTG terminal, the vehicle and the user terminal automatically establish a communication connection with each other through wireless communication such as Bluetooth, and receive information from the vehicle sharing management server according to the vehicle sharing reservation. By performing user authentication through an authentication code, we would like to propose a method to receive car sharing services by confirming whether the user who reserved the car sharing service is the correct user.

In addition, the present invention allows the authentication code provided from the car sharing management server to the DTG terminal and the user terminal to be changed periodically or aperiodically, and in the process of changing the authentication code, the vehicle is in a communication failure area (shaded area). When located, the authentication code of the DTG terminal can be changed by using the user terminal as a repeater without the user being able to intervene.

Hereinafter, a preferred embodiment of the automatic vehicle sharing user authentication system of the present invention will be described in detail with reference to the attached drawings. The same reference numerals in each drawing indicate the same member. In addition, specific structural and functional descriptions of the embodiments of the present invention are merely illustrative for the purpose of explaining the embodiments of the present invention, and unless otherwise defined, all terms used herein, including technical or scientific terms, are provided. They have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms as defined in commonly used dictionaries should be interpreted as having meanings consistent with the meanings they have in the context of the related technology, and unless clearly defined in this specification, should not be interpreted in an idealized or overly formal sense. It is desirable not to.

Figure 1 is a diagram for explaining the configuration of an automatic vehicle sharing user authentication system according to an embodiment of the present invention.

As shown in FIG. 1, the present invention includes a car sharing user automatic authentication device 100, a DTG terminal 200, a car sharing management server 300, and a database 400.

The vehicle sharing user automatic authentication device 100 refers to an app installed on a user terminal such as a smartphone or tablet PC.

At this time, the vehicle sharing user automatic authentication device 100 is not implemented in the form of an app on a user terminal such as a smartphone, but is configured as an independent wearable device so that the user can wear it on a part of the body or carry it around.

The car sharing user automatic authentication device 100 communicates with the car sharing management server 300 through a network, and allows the user to make a reservation related to car sharing. That is, the reservation data including usage time, cost, payment method, pickup location, and return location entered or selected by the user who has confirmed the vehicle information available for use of the vehicle sharing service provided by the vehicle sharing management server 300 is managed for the vehicle sharing. By transmitting it to the server 300, a shared vehicle reservation can be made.

In addition, the car sharing user automatic authentication device 100 receives an authentication code according to the car sharing reservation from the car sharing management server 300 and stores it.

At this time, the authentication code provided by the car sharing management server 300 is generated in consideration of the vehicle used for car sharing and the user terminal of the user who will use the vehicle, and is a smart phone that can unlock or start the vehicle. It can serve as a smart key, and is simultaneously provided to the DTG terminal 200 provided in the vehicle the user will use, along with the automatic vehicle sharing user authentication device 100.

Thereafter, when a user possessing the vehicle sharing user automatic authentication device 100 approaches a vehicle parked at a predetermined location at the reserved time, the vehicle sharing user automatic authentication device 100 and the DTG terminal provided in the vehicle A communication connection is established between (200). At this time, the communication connection between the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 is preferably performed through Bluetooth pairing using BLE (Bluetooth Low Energy), and various communication methods such as Zigbee and beacon are used. Please note that can be applied.

Subsequently, the vehicle sharing user automatic authentication device 100 transmits the authentication code provided from the vehicle sharing management server 300 to the DTG terminal 200, and the DTG terminal 200 automatically authenticates the vehicle sharing user. The authentication code received from the device 100 is compared with the authentication code provided and stored by the car sharing management server 300 to check whether they match, and if the authentication code matches, the user who reserved the car sharing Complete user authentication to check if it is correct. Once user authentication is completed in this way, the user can unlock the vehicle, start the engine, and drive.

If user authentication is performed using the user terminal owned by the user and the DTG terminal provided in the vehicle, it is possible to prevent the vehicle from being used indiscriminately or illegally because the reservation person and the actual user are different, and a separate service for user authentication is possible. There is no need to have the necessary equipment, and even if an accident occurs while driving the vehicle, normal insurance processing can be performed.

Meanwhile, the communication connection between the car sharing user automatic authentication device 100 and the DTG terminal 200 to use the car sharing service uses the phone number of the user terminal, and for user authentication who made a car sharing reservation, authentication Although it is preferred to use a code, it is also possible to perform communication connection or user authentication through an authentication code, the phone number of the user terminal, the user's driving license, or a combination thereof.

Additionally, the authentication code may use authentication codes with different depths or multiple authentication codes depending on the user's level of use of the shared vehicle.

Here, using authentication codes with different depths means that, for example, when trying to open the door or trunk of a vehicle, the authentication code used for user authentication (i.e., the authentication code provided by default according to car sharing reservations) is used to authenticate the user. In the case of startup, this means using an authentication code that includes license information in addition to the authentication code above. In other words, an authentication code with a deep depth (e.g. number of bits) is used depending on the importance of vehicle use.

Additionally, using multiple authentication codes means using different authentication codes for opening the door or trunk, starting the engine, etc.

Additionally, the car sharing user automatic authentication device 100 can perform car sharing registration with the car sharing management server 300. In other words, an individual who owns a vehicle performs vehicle sharing registration to allow others to use his or her vehicle through vehicle sharing, or a company that operates vehicles including taxis, trucks, and buses provides the vehicle to a driver. Vehicle sharing registration can be performed to entrust the assignment and management tasks.

The DTG terminal 200 is mounted on a vehicle and records the speed when driving the vehicle, location information (GPS), presence or absence of braking, moving distance, revolutions per minute (RPM) of the engine, amount of impact to the vehicle, or a combination thereof. It is a device that records and stores vehicle operation records in real time. At this time, the vehicle operation record recorded and stored in real time according to the vehicle operation can be regularly submitted to a transportation administrative agency such as the Korea Transportation Safety Authority through its own communication means.

In particular, when a user holding the vehicle sharing user automatic authentication device 100 approaches the vehicle, the DTG terminal 200 performs mutual communication connection through wireless communication and receives information from the vehicle sharing management server 300. Perform user authentication using the provided authentication code.

This is one of the main features of the present invention. In the present invention, when a user takes over a vehicle at a predetermined location, a communication channel is formed between the vehicle sharing user automatic authentication device 100 and the DTG terminal 200, and then The DTG terminal 200 compares the authentication code provided from the automatic car sharing user authentication device 100 through the communication channel with a pre-stored authentication code to check whether the user who has reserved the car sharing is the one, The vehicle can be used based on the user authentication confirmed above.

Additionally, the DTG terminal 200 may receive information about the phone number of the user terminal in addition to the authentication code from the car sharing management server 300. In this case, the DTG terminal 200 receives the phone number of the user terminal broadcasted from the user terminal when the user approaches the vehicle location to take over the reserved vehicle, and combines it with the phone number of the pre-registered user terminal. A communication connection (e.g. Bluetooth pairing) is performed with the corresponding user terminal depending on whether it matches or not. In other words, a specific vehicle (DTG terminal) can access one of multiple user terminals (i.e., an automatic vehicle sharing user authentication device installed in the form of an app) through short-distance communication. In this way, a communication connection must first be established between the automatic car sharing user authentication device 100 and the DTG terminal 200 to perform user authentication using the authentication code provided from the car sharing management server 300.

Meanwhile, unlike the method described above, the user terminal (i.e., the automatic car sharing user authentication device) may receive information about the DTG terminal in addition to the authentication code from the car sharing management server 300. In this case, the vehicle sharing user automatic authentication device 100 is configured to detect the DTG terminal 200 of the vehicle when the user approaches the vehicle to take over the reserved vehicle and scans nearby equipment by inputting information about the DTG terminal. Establish a communication connection with In other words, a specific user terminal (i.e., an automatic vehicle sharing user authentication device installed in the form of an app) can access one of multiple vehicles (DTG terminal) through short-distance communication. After communication connection is established between the automatic vehicle sharing user authentication device 100 and the DTG terminal 200, user authentication can be performed using the authentication code.

That is, communication connection (communication session connection) between the car sharing user automatic authentication device 100 and the DTG terminal 200 through Bluetooth pairing selectively uses the DTG terminal 200 as the master depending on the usage environment of the car sharing service. This can be performed by using the vehicle sharing user automatic authentication device 100 as the master.

The car sharing management server 300 is a server computer operated directly or by entrustment by the business providing the car sharing service. When the car sharing service is reserved from the car sharing user automatic authentication device 100, according to the car sharing reservation, An authentication code is generated, and the generated authentication code is transmitted and stored in the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 provided in the reserved vehicle, respectively.

That is, when a user wants to take over a vehicle at a predetermined location, a communication connection is established between the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 using the authentication code, the phone number of the user terminal, etc., The DTG terminal 200 compares the authentication code provided from the automatic car sharing user authentication device 100 with the authentication code stored in the car sharing management server 300 to confirm whether the user has made a reservation. will be.

At this time, the car sharing management server 300 periodically or aperiodically changes and updates the authentication code provided to the car sharing user automatic authentication device 100 and the DTG terminal 200, respectively, according to the user's car sharing reservation. can do.

This is one of the main features of the present invention. In the present invention, in order to fundamentally block illegal use due to leakage or hacking of the authentication code generated according to the user's car sharing reservation, the authentication code is changed from time to time, and the changed authentication code is changed. The authentication code is provided to the vehicle sharing user automatic authentication device 100 and the DTG terminal 200, respectively.

Meanwhile, the car sharing management server 300 is in a state in which the user cannot intervene (or is not aware of it) when communication is impossible, such as when the vehicle is located in a communication failure area (shaded area) such as a tunnel or underground. ), the vehicle sharing user automatic authentication device 100 can be used as a repeater to communicate with the DTG terminal 200.

For example, in the process of providing an authentication code that changes from time to time from the car sharing management server 300 to the car sharing user automatic authentication device 100 and the DTG terminal 200, respectively, the DTG terminal 200 of the vehicle ), when communication with the car sharing management server 300 is impossible, the car sharing management server 300 communicates with the DTG terminal 200 by using the car sharing user automatic authentication device 100 owned by the user driving the car as a repeater, It can be updated by providing the changed authentication code to the DTG terminal 200.

In addition, when the car sharing management server 300 changes the authentication code and provides it to the car sharing user automatic authentication device 100 and the DTG terminal 200 respectively to update, the car sharing user automatic authentication device 100 By leaving the authentication code the same and changing only the authentication code of the DTG terminal 200, the continued use of the vehicle may be restricted.

For example, if a specific vehicle leaves the region or country under the operator's jurisdiction or is used for a crime, the user can no longer operate the specific vehicle.

Additionally, the car sharing management server 300 may store and manage information on car sharing registration input from the car sharing user automatic authentication device 100 in the database 400. For example, it is possible to store and manage information about vehicle sharing registration by individuals who own vehicles, vehicle sharing registration by companies that operate vehicles such as taxis, trucks, and buses.

The database 400 stores and manages reservation status for each vehicle and user related to the use of the car sharing service.

Additionally, the database 400 stores and manages information on vehicle sharing registration separately for each individual and company.

Figure 2 is a diagram for explaining the processing flow of the automatic vehicle sharing user authentication system according to an embodiment of the present invention.

As shown in FIG. 2, the car sharing user automatic authentication device 100 runs a pre-installed app according to the operation of the user who wishes to make a car sharing reservation and establishes a communication connection with the car sharing management server 300. do.

Next, the car sharing user automatic authentication device 100 displays currently available reservation information (e.g., information such as time, vehicle pickup location, cost, payment method, etc.) on the screen for the user to confirm, and the user who confirms this A car sharing reservation is made according to the selection, and information about the car sharing reservation is transmitted to the car sharing management server 300 (①).

Then, the car sharing management server 300 generates an authentication code used for user authentication according to the car sharing reservation performed by the car sharing user automatic authentication device 100, and sends the generated authentication code to the It is transmitted to the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 provided in the vehicle, respectively, and stored and managed (②).

Here, the authentication code provided by the car sharing management server 300 may be changed periodically or aperiodically. When the authentication code is changed, the car sharing management server 300 sends the changed authentication code to the above. It is provided to the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 respectively to be updated.

At this time, if it is confirmed that the changed authentication code has not been normally provided to the DTG terminal 200 and updated (for example, meaning that the confirmation (ack) signal that the changed authentication code has been received is not returned), the vehicle The sharing management server 300 can provide and update the changed authentication code to the DTG terminal 200 via the vehicle sharing user automatic authentication device 100 (②-1).

Now, in the process of storing and managing the authentication code (including the updated and changed authentication code) according to the car sharing reservation in the car sharing user automatic authentication device 100 and the DTG terminal 200, the user can use the car. When the vehicle is approached at the reserved time, the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 provided in the vehicle perform wireless communication with each other to form a communication channel (③).

For example, when a user approaches the vehicle location to take over a reserved vehicle, the DTG terminal 200 receives the phone number of the user terminal broadcast from the vehicle sharing user automatic authentication device 100, and receives it. A communication connection can be made with the user terminal depending on whether it matches the phone number of the already registered user terminal.

In addition, the car sharing user automatic authentication device 100 checks nearby Bluetooth-based devices based on information about the DTG terminal of a specific vehicle provided by the car sharing management server 300 and detects the DTG of a specific vehicle to be used for car sharing. It is also possible to perform automatic pairing with the terminal 200.

In this way, after the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 are connected to each other through Bluetooth pairing, etc. and a communication channel is formed, the authentication stored in the vehicle sharing user automatic authentication device 100 The code is transmitted to the DTG terminal 200 (④).

Subsequently, the DTG terminal 200 compares the authentication code received from the vehicle sharing user automatic authentication device 100 with the pre-stored authentication code to determine whether it matches, and if it matches, confirms that the user has been authenticated, and determines whether the authentication code matches the pre-stored authentication code. Unlock the vehicle, start the engine, and allow the vehicle to be driven (⑤).

Figure 3 is a block diagram showing in detail the configuration of an automatic vehicle sharing user authentication device according to an embodiment of the present invention.

As shown in FIG. 3, the car sharing user automatic authentication device 100 includes a first communication unit 110, a car sharing reservation unit 120, a first reception unit 130, a user authentication unit 140, and a first It is comprised of an update unit 150, a connection relay unit 160, a memory 170, etc.

When the app for using the car sharing service is executed, the first communication unit 110 establishes a communication connection with the car sharing management server 300, and provides information on vehicles that can use the car sharing service with the car sharing management server 300, Transmits and receives data related to reservation data and authentication codes according to car sharing reservations.

In addition, the first communication unit 110 connects the DTG terminal 200 provided in the vehicle and the user's user terminal through short-distance communication as the user approaches the vehicle for using the car sharing service. That is, a communication channel is formed through Bluetooth pairing with the DTG terminal 200 located in close proximity to the car sharing user automatic authentication device 100, and an authentication code for using the car sharing service is generated through the formed communication channel. It is transmitted to the DTG terminal 200 to perform user authentication to use the vehicle.

For example, when the user approaches the reserved vehicle to take over the vehicle and scans nearby equipment by inputting information about the DTG terminal, the first communication unit 110 communicates with the DTG terminal 200 of the vehicle. A communication channel can be formed. That is, a communication channel through Bluetooth pairing can be formed with the DTG terminal 200 using the vehicle sharing user automatic authentication device 100 as a master.

At this time, the communication channel can be formed using various wireless communication methods such as ZigBee and beacons in addition to Bluetooth. When forming the communication channel, the phone number of the user terminal, the authentication code, etc. can be used.

In addition, the first communication unit 110 receives data on the changed authentication code related to the car sharing service from the car sharing management server 300 connected to communication through a network and transmits it to the first update unit 150. .

The car sharing reservation unit 120 displays on the screen information on vehicles available for car sharing service provided by the car sharing management server 300 through the first communication unit 110, and the user who confirms this enters the information. Reservation data including time, cost, payment method, pickup location, and return location are provided to the vehicle sharing management server 300 through the first communication unit 110 to make a vehicle sharing reservation.

The first receiver 130 receives an authentication code considering the vehicle and the user terminal of the user who will use the vehicle from the car sharing management server 300 through the first communication unit 110, and sends the received authentication code. It is stored in the memory 170.

The user authentication unit 140 performs user authentication by providing an authentication code according to the car sharing reservation stored in the memory 170 to the DTG terminal 200. That is, by transmitting the authentication code to the DTG terminal 200 through a communication channel established through the first communication unit 110, the user of the vehicle can be authenticated.

At this time, the authentication code alone or together with the phone number of the user terminal establishes a communication connection (i.e., forms a communication channel) between the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 and allows the user to drive the vehicle. It can be used for user authentication. In addition, as described above, authentication codes with different depths (i.e., authentication codes with different number of bits) or multiple authentication codes can be used depending on the degree of use of the vehicle.

The first update unit 150 receives a periodically or aperiodically changed authentication code from the car sharing management server 300 through the first communication unit 110, and stores the changed authentication code in the memory 170. ) and update it.

At this time, the user authentication unit 140 transmits the authentication code updated through the first update unit 150 to the DTG terminal 200 through a communication channel formed by the first communication unit 110. Accordingly, the DTG terminal 200 additionally performs user authentication based on comparison with the updated authentication code provided by the car sharing management server 300 to enable continuous use of the car sharing service.

The access relay unit 160 manages the vehicle sharing when the DTG terminal 200 is unable to communicate with the vehicle sharing management server 300 or is in a shadow area (e.g., tunnel, underground, etc.) for a long time. The server 300 performs a function that allows connection to the DTG terminal 200 through a user terminal.

For example, when updating the changed authentication code in the car sharing management server 300 by transmitting it to the car sharing user automatic authentication device 100 and the DTG terminal 200, the DTG terminal 200 and If communication fails and the changed authentication code provided by the car sharing management server 300 is not received, the changed authentication code is sent to the DTG terminal 200 via the car sharing user automatic authentication device 100. ) so that it can be provided.

At this time, the access relay unit 160 must prevent the user from accessing data provided by the car sharing management server 300. Additionally, it can be relayed to the DTG terminal 200 without the user being aware of it (e.g. running a hidden app).

The memory 170 stores various operation programs used in the automatic car sharing user authentication device 100, and stores and manages authentication codes (including updated authentication codes) according to car sharing reservations.

Figure 4 is a block diagram showing in detail the configuration of a DTG terminal according to an embodiment of the present invention.

The vehicle driving record unit 210 stores driving record information on speed, location, braking presence, moving distance, engine status, etc. in real time when the vehicle is driven, and the stored driving record information is sent through the second communication unit 220. The driving record is provided to the relevant organization (not shown) that manages and supervises it.

The second communication unit 220 forms a communication channel through Bluetooth pairing with the vehicle sharing user automatic authentication device 100 as the user for using the vehicle sharing service approaches, and shares the vehicle through the formed communication channel. Data on the authentication code for using the car sharing service is received from the automatic user authentication device 100 and transmitted to the second receiving unit 230.

For example, the second communication unit 220 receives the phone number of the user terminal broadcasted from the user terminal (i.e., automatic vehicle sharing user authentication device) owned by the user approaching the vehicle location to take over the reserved vehicle. If so, it is compared with the phone number of the pre-registered user terminal to check whether it matches, and if it matches, a communication channel can be formed through Bluetooth pairing with the user terminal. That is, a communication channel can be formed through Bluetooth pairing with the vehicle sharing user automatic authentication device 100 using the DTG terminal 200 as a master.

In addition, the second communication unit 220 communicates with the car sharing management server 300 through a network, and receives an authentication code (including a changed authentication code) for each user related to the car sharing service from the car sharing management server 300. Receive data about

The second receiver 230 receives an authentication code considering the vehicle and the user terminal of each user who will use the vehicle from the car sharing management server 300 through the second communication unit 220, and receives the received authentication code. is stored in the memory 260.

In addition, the second receiver 230 receives an authentication code for user authentication of the vehicle from the automatic vehicle sharing user authentication device 100 through the communication channel formed by the second communication unit 220, and the received The authentication code is transmitted to the user authentication processing unit 240.

When the authentication code for user authentication is delivered from the second receiver 230, the user authentication processing unit 240 compares it with the authentication code for user authentication of the corresponding vehicle received from the automatic car sharing user authentication device 100. And, if the authentication code matches as a result of the comparison, the user is authenticated as the user who reserved the car sharing, and the authentication result is provided to the vehicle's control module (e.g. ECU) to open the vehicle's door, start the vehicle, etc. Allow it to operate.

In addition, the user authentication processing unit 240 receives the authentication code updated through the second update unit 250 from the vehicle sharing user automatic authentication device 100 through a communication channel formed by the second communication unit 220. It is compared with the updated authentication code, and the car sharing service can be continuously used based on the comparison results.

The second update unit 250 periodically or aperiodically changes an authentication code from the car sharing management server 300 through the second communication unit 220 (i.e., an authentication code for each user who has reserved a car sharing service). is received, and the changed authentication code is stored and updated in the memory 260.

The memory 260 stores various operation programs used in the DTG terminal 200, and stores and manages authentication codes for each user (including updated authentication codes) according to car sharing reservations.

Figure 5 is a block diagram showing in detail the configuration of a car sharing management server according to an embodiment of the present invention.

Performs transmission and reception.

In addition, the third communication unit 310 transmits an authentication code that changes periodically or aperiodically based on the control of the authentication code provider 340 to each of the vehicle sharing user automatic authentication device 100 and the DTG terminal 200. do.

The car sharing reservation processing unit 320 provides information on vehicles that can use the car sharing service to the car sharing user automatic authentication device 100 that is connected to communication through the third communication unit 310, and automatically authenticates the car sharing user. Based on the reservation data input from the device 100, each user's car sharing reservation is made, and information about the car sharing reservation is stored and managed in the database 400.

When a specific user makes a car sharing reservation through the car sharing reservation processing unit 320, the authentication code generator 330 generates an authentication code according to the car sharing reservation, and converts the generated authentication code into the authentication code. It is delivered to the provision unit 340.

The authentication code providing unit 340 sends the authentication code generated by the authentication code generating unit 330 to the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 through the third communication unit 310. Please send them separately.

The authentication code update processing unit 350 changes the authentication code provided to the automatic car sharing user authentication device 100 held by the user who made the car sharing reservation and the DTG terminal 200 provided in the specific vehicle to be used by the user. If there is a need to change, change the authentication code and then provide the changed authentication code to the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 through the third communication unit 310 to update. do.

Meanwhile, when the authentication code update processing unit 350 transmits and updates the changed authentication code to the vehicle sharing user automatic authentication device 100 and the DTG terminal 200, respectively, the vehicle sharing user automatic authentication device 100 ) The use of the vehicle can be restricted by leaving the authentication code stored in the same and updating only the authentication code of the DTG terminal 200.

The communication failure confirmation unit 360 checks whether the car sharing management server 300 is unable to communicate directly with the DTG terminal 200 through the network, and as a result of the confirmation, the DTG terminal 200 ), if it is confirmed that there is a failure state in which communication is not connected, information about this is provided to the authentication code update processing unit 350. That is, the authentication code changed by the authentication code update processing unit 350 is first transmitted to the vehicle sharing user automatic authentication device 100 located in close proximity to the DTG terminal 200, and the vehicle sharing user automatic authentication device 100 The purpose is to provide the changed authentication code to the DTG terminal 200 forming a communication channel.

Next, an embodiment of the car sharing user automatic authentication method according to the present invention configured as described above will be described in detail with reference to FIGS. 6 and 7. At this time, the order of each step according to the method of the present invention may be changed depending on the usage environment or a person skilled in the art.

Figure 6 is a flowchart showing in detail the operation process of the automatic authentication method for a car sharing user according to an embodiment of the present invention.

As shown in Figure 6, the car sharing user automatic authentication device 100 performs a communication connection to the car sharing management server 300 through the network according to the user's execution of the app (S110).

Subsequently, the car sharing user automatic authentication device 100 receives information on vehicles that can use the car sharing service from the car sharing management server 300, and the usage time, cost, payment method, and pickup location entered by the user who confirmed this. And reservation data including the return location is provided to the car sharing management server 300 to make a car sharing reservation (S120).

When a car sharing reservation is made by the user through step S120, the car sharing management server 300 generates an authentication code considering the vehicle and the user terminal of the user who will use the vehicle (S130), and enters the generated authentication code. It is transmitted to the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 provided in the vehicle, respectively (S140).

After the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 store the authentication code according to the vehicle sharing reservation through step S140, as the user approaches the vehicle at the reserved time for vehicle use, The vehicle sharing user automatic authentication device 100 determines whether a communication connection is established with the DTG terminal 200 (S150).

For example, the vehicle sharing user automatic authentication device 100 establishes itself as the master and forms a communication channel through Bluetooth pairing with the DTG terminal 200, or the DTG terminal 200 establishes itself as the master. It is determined whether a communication channel has been established through Bluetooth pairing with the vehicle sharing user automatic authentication device 100.

As a result of the determination in step S150, if a communication channel is formed between the vehicle sharing user automatic authentication device 100 and the DTG terminal 200, the vehicle sharing user automatic authentication device 100 communicates with the DTG terminal through the communication channel. User authentication is requested by transmitting the authentication code stored and managed through step S140 to (200) (S160).

Next, the DTG terminal 200 determines whether user authentication has been completed by comparing the authentication code provided from the automatic vehicle sharing user authentication device 100 with the authentication code stored and managed in step S140 (S170) .

If user authentication is not completed as determined through step S170, the DTG terminal 200 notifies that user authentication has not been completed and terminates the car sharing service (S171).

In addition, when user authentication is completed as determined through step S170, the DTG terminal 200 grants control rights such as opening and closing vehicle doors and starting the vehicle to the user so that the user can drive the vehicle (S180).

Meanwhile, the authentication code according to the car sharing reservation stored and managed in each of the car sharing user automatic authentication device 100 and the DTG terminal 200 can be updated periodically or aperiodically in the car sharing management server 300. . In other words, the authentication code can be changed and managed at any time in order to prevent vehicle theft or illegal use due to leakage or hacking of the authentication code.

In this process, the car sharing management server 300 prevents the user from intervening when normal communication with the DTG terminal 200 is not achieved because the vehicle is located in a communication failure area such as a tunnel or underground. The authentication code can be changed by using the vehicle sharing user automatic authentication device 100 as a repeater to communicate with the DTG terminal 200.

Figure 7 is a flowchart showing in detail the operation process of relaying and updating the changed authentication code to the DTG terminal through the automatic vehicle sharing user authentication device according to an embodiment of the present invention.

As shown in FIG. 7, the car sharing management server 300 determines whether the authentication code provided to each of the car sharing user automatic authentication device 100 and the DTG terminal 200 is changed (S210).

If the authentication code is changed as a result of the determination in step S210, the car sharing management server 300 provides the changed authentication code to each of the car sharing user automatic authentication device 100 and the DTG terminal 200 (S220) , it is determined whether reception of the changed authentication code has been confirmed in each of the vehicle sharing user automatic authentication device 100 and the DTG terminal 200 (S230).

If reception of the authentication code is not confirmed as a result of the determination in step S230, the car sharing management server 300 determines whether communication is not possible because the DTG terminal 200 is located in a communication failure area (S240).

If it is determined in step S240 that communication with the DTG terminal 200 is not possible, the car sharing management server 300 first transmits the changed authentication code to the car sharing user automatic authentication device 100 ( S250).

Subsequently, the car sharing user automatic authentication device 100 transmits the changed authentication code received from the car sharing management server 300 to the DTG terminal 200 forming a communication channel while preventing user intervention. so that it can be updated (S260).

Meanwhile, although not shown in FIG. 7, when the car sharing management server 300 transmits and updates the changed authentication code to the car sharing user automatic authentication device 100 and the DTG terminal 200, respectively, The authentication code stored in the automatic vehicle sharing user authentication device 100 may be maintained as is, and only the authentication code of the DTG terminal 200 may be updated to limit the use of the vehicle.

In this way, in the present invention, when a user who has reserved a car sharing service picks up a vehicle at a predetermined location, the DTG terminal and the user terminal perform user authentication through wireless communication such as Bluetooth at close range to reserve the car sharing service. Since it is confirmed that one user is the correct user, it is possible to prevent users other than the person making the reservation from using the vehicle indiscriminately.

In addition, since the present invention periodically or aperiodically changes the authentication code for using the car sharing service provided by the car sharing management server to the DTG terminal and user terminal, vehicle theft due to leakage or hacking of the authentication code can be suppressed as much as possible. You can.

In addition, in the process of changing the authentication code of the DTG terminal and the user terminal in the car sharing management server, the present invention provides the DTG terminal with the user of the user terminal unable to intervene when the vehicle is located in a communication failure area. Since the authentication code can be changed by communicating with , the authentication code can be changed smoothly and errors are prevented from occurring in user authentication using the authentication code.

In addition, in the present invention, in the process of changing the authentication code of the DTG terminal and the user terminal in the car sharing management server, only the authentication code of the DTG terminal can be changed without changing the authentication code of the user terminal, so the vehicle does not leave the predetermined area. Or, the use of vehicles can be urgently restricted when they are used for crimes.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and various modifications and other equivalent embodiments can be made by those skilled in the art. You will understand that it is possible. Therefore, the scope of technical protection of the present invention should be determined by the scope of the patent claims below.
