Description

Vehicle boarding management device and method using high precision low power bluetooth signal encryption

The present invention relates to a vehicle occupancy management apparatus and method using high-precision low-power Bluetooth signal encryption, and in particular, high-precision low-power Bluetooth (Bluetooth) that enables location confirmation when boarding a vehicle by encrypting an advertising signal transmitted from a high-precision low-power Bluetooth (BLE) device into a pattern. It relates to a vehicle occupancy management apparatus and method using signal encryption.

Recently, the application of IoT technology based on Bluetooth Low Energy (BLE) is spreading in various fields.

Because BLE technology dramatically reduces power consumption compared to existing Bluetooth technology, it guarantees long-term battery life while wirelessly connecting two-way communication between various devices. In addition, it is compatible with smartphones and has a rich user interface.

It offers advantages such as pace and quick and easy connection. Recently, BLE technology is being supported in major new smartphones along with major operating systems such as iOS, Android, and Windows, and its use is gradually expanding.

In this regard, recently, beacon technology is emerging as a simple signal generating device that sends its own unique identifier information (ID), and various IoT technologies using it are emerging. Beacon is a Bluetooth 4.0-based protocol That is, it is a device that transmits a signal to a nearby device using Bluetooth Low Power (BLE). The advantage of beacons is that low-power wireless communication is possible, so you can use them without worrying about the power consumption of devices.

When location is recognized when riding in a vehicle using this high-precision BLE (Bluetooth Low Energy), pairing is performed between the BLE device worn by the user and the bus terminal, which is a Bluetooth reader, and when pairing is made, the advertising transmitted from the BLE device in the bus terminal Receives a signal and transmits it to a remote server. The remote server extracts user information based on the advertising signal transmitted from the bus terminal and authenticates the user through DB search.

Therefore, when a BLE device is used as an authentication device for user location tracking, a complicated procedure of pairing is required, and security is also weak because the user is verified by analyzing the advertising signal received from the BLE device.

On the other hand, a conventionally proposed technique for managing access based on BLE beacon is disclosed in Korean Patent Registration No. 10-1797231. IoT-based beacon tags attached to visitor passes in security area buildings, facilities, and ports and beacon APs installed in various areas that can sense them are provided. When the beacon tag attached to the pass unilaterally transmits the device ID (Tag ID) and RSSI (Received signal strength indicator) values at regular intervals, the beacon AP recognizes the device ID (Tag ID) and RSSI of the beacon tag. Value and GPS location information of the beacon AP are transmitted to the access management system. Access management using the beacon tag attached to the pass in buildings, facilities, and port container terminals in the secure area, tracking the location of the beacon tag attached to the pass and monitoring the movement path by the RTLS (Real Time Location Service) server. It displays this on the GIS map and provides access security management that manages the movement of visitors with beacon-tagged passes and location-based beacon-tagged tangible assets and hazardous materials management.

However, this prior art also requires a complicated procedure of pairing, and also has a disadvantage in that security is weak because user verification is performed by analyzing a signal received from a BLE device. For example, since the signal transmitted from the BLE device is not encrypted, it is vulnerable to security.

6 is a flowchart showing a vehicle boarding management method using high-precision low-power Bluetooth signal encryption according to the present invention. (S10), (b) receiving the encrypted data transmitted from the user's BLE device 100 in the vehicle terminal 200, respectively, to the vehicle control server 400 through the network 300 Transmitting steps (S20 - S50), (c) the vehicle control server 400 compares the encrypted data transmitted from the vehicle terminal 200 with the stored encrypted data to recognize a user, and the recognized user is a management target user It includes a step (S60 - S70) of transmitting the user location information to the management target terminal (500).

A vehicle occupancy management apparatus and method using high-precision low-power Bluetooth signal encryption according to the present invention configured as described above will be described in detail as follows.

First, in order to check the location of the management target such as the elderly, the elderly with dementia, and children, the user BLE device 100 and the vehicle control server 400 carried or worn by the management target generate encrypted data for user recognition, respectively. Save (S10). Here, in the storage unit 403 of the vehicle control server 400, the management target unique information (ID) and encrypted data are matched and stored in order to recognize the management target.

Encrypted data for recognizing a management target may be encrypted in a different pattern for each user in order to identify the user.

For example, as shown in FIG. 3 , the encrypted data may be generated by encrypting the BLE Advertising CH timing with a pattern. When the timing of each channel (CH) is defined as a different value (n1s ~ n4s) between BLE1 ~ BLE5, which is the user's BLE device, the advertising signal is encrypted by combining the BLE pattern counter and 4 types of timing and patterning it into 1n1s2n2s3n3s4n4s5. . In addition to this method, encrypted data is generated by making the BLE Advertising CH timing in a timing pattern of various combinations (1n1s…N-1nxsN). Here, even if the BLE Advertising CH is changed, the timing pattern data value between CHs does not change.

As another method, as shown in FIG. 4 , the encrypted data may be generated by encrypting the BLE Advertising CH with a pattern. When the user's BLE device, BLE1 ~ BLE5 CH between BLE1 ~ BLE5 is combined and defined as 5 types such as C37C37, C37C37, C39C39, C38C38, C38C38, the BLE pattern counter and 5 types of CH combinations are patterned to 1C37C372C37C373C39C394C38C385C38C38 to pattern the advertising signal. Encrypt. In addition to this method, encrypted data is generated by making BLE Advertising CH with CH patterns of various combinations (1C37~39C37~39…NC37~39C37~39). N (pattern counter) = When the same CH is repeated twice (C37~39 C37~39), it is recognized as N times. Even if the BLE Advertising CH is patterned, the timing is equally applied as the BLE CHIP Default Timing value.

As another method, as shown in FIG. 5 , the encrypted data may be generated by combining encrypted data obtained by encrypting the BLE Advertising CH timing as a pattern and encrypted data obtained by encrypting the BLE Advertising CH as a pattern. When Timing + CH between BLE1 ~ BLE4, which is the user's BLE device, is defined as 4 types of n1s ~ n4s + 4 types of C37C37, C37C37, C39C39, C38C38 of different values, the BLE pattern counter and Timing + CH are combined to form a 1C37n1sC372C37n2sC373C39n3sC394 pattern. or 1C37-39n1sC37-39… By creating Timing + CH patterns of various combinations such as NC37~39nxsC37~39, it is possible to generate encrypted data by encrypting the BLE Advertising signal. N (pattern counter) = The same CH is repeated twice (C37~39 C37~39), and when the timing value between pattern CHs is included, it is recognized as N times.

As described above, the user wears or carries the user BLE device 100 that stores the encrypted data obtained by encrypting the advertising signal in a different pattern for each user in the storage unit 101, and the vehicle terminal 200 as shown in FIG. 2A. Board the bus 1 equipped with (S20). Here, it is assumed that a user wearing or carrying the user BLE device 100 is a management target user.

When the management target user wearing or carrying the user BLE device 100 rides the vehicle 1, the BLE 201 of the vehicle terminal 200 receives the encrypted data transmitted from the user BLE device 100. (S30). Here, the user BLE device 100 simply transmits stored encrypted data without a pairing process with the vehicle terminal 200 . It can be said that communication is connected and made only by receiving the encrypted data transmitted from the user BLE device 100 in the vehicle terminal 200 .

Upon receiving the pattern-encrypted encrypted data, the control unit 203 of the vehicle terminal 200 compares it with the encrypted pattern stored in the storage unit 202 to confirm whether it is pre-registered encrypted data (S40). That is, it is checked whether the data is encrypted by the registered encryption pattern. Here, the vehicle terminal 200 does not analyze the received encrypted data, but simply checks whether the received data is data encrypted with a predetermined encryption pattern.

As a result of this check, if the received encrypted data is not encrypted with a predetermined encryption pattern, the received encrypted data is discarded. Otherwise, if the received encrypted data is encrypted with a predetermined encryption pattern, the received encrypted data is transmitted to the communication unit ( 204) through the vehicle control server 400 (S50). Here, the communication unit 204 may communicate using a communication protocol such as LTE or 5G.

The encrypted data receiving unit 401 of the vehicle control server 400 receives the encrypted data transmitted from the vehicle terminal 200 . Next, as shown in FIG. 2B , the user recognition unit 402 recognizes the user by comparing the received encrypted data with the stored encrypted data. Then, it is checked whether the recognized user is a management target user (S60), and if the user is a management target user, user location information is generated and transmitted to the management target terminal 500 (S70). Here, it is preferable that the management target user be registered in the vehicle control server 400 through the management target terminal 500 in advance. For example, when the user to be managed is an elderly person with dementia, by registering in advance user recognition information that matches the unique information (ID) of the elderly with dementia and the pattern encryption data registered in the user BLE device carried by the elderly with dementia, simple management It is possible to determine whether a target user exists.

That is, according to the present invention, a pattern for user identification is stored as encrypted data in the user BLE device of the management target user, and when the management target user gets on a vehicle such as a bus, the vehicle terminal receives the encrypted data transmitted from the user BLE device and transmit it to the vehicle control server. The vehicle control server recognizes the user by comparing the received encrypted data with the stored encrypted data, and if the recognized user is a pre-registered management target user, the user location information is transmitted to the management target terminal in real time by the manager or the manager integrated server Allows the location of the management target to be identified.
