Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method and apparatus for transmitting / receiving data using a low-power Bluetooth beacon in a wireless communication system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wireless communication, and more particularly, to a method and apparatus for transmitting and receiving data between a plurality of terminals using a low-power Bluetooth low energy beacon. In particular, the present invention relates to a method and apparatus for preventing copying of a low-power Bluetooth low energy beacon based on Bluetooth 4.0 (BLE, Bluetooth Low Energy).

Recently, the data transmission amount of the wireless communication network is rapidly increasing. This is due to the advent and spread of various devices such as machine-to-machine (M2M) communications and smart phones and tablet PCs that require high data throughput.

A carrier aggregation (CA) technique, a cognitive radio technique, and the like that efficiently use more frequency bands in order to satisfy a required high data transmission amount, a multi-antenna technique to increase data capacity within a limited frequency, And base station cooperative transmission technology.

In addition, as the ubiquitous environment comes into the market, there is a rapid increase in the demand for providing continuous service without regard to time and place by using the equipment.

Accordingly, a plurality of terminals communicating with each other through a base station establish a cooperative system, and the wireless communication network evolves in a direction that at least one terminal cooperates to transmit or receive data according to a communication environment.

Here, a plurality of terminals are connected to other terminals in a wireless communication system, and a source device and a source device, which are subjects to communicate with a base station with the help of other terminals, Cooperative devices that act as intermediaries to provide feedback and cooperative devices other than Source Devices that do not act as cooperative devices.

A wireless communication system with high density terminals can exhibit higher system performance by cooperation between terminals. For example, in the case of transmitting predetermined data to a base station, a source device can transmit the data together with a cooperative device. Also, the source device may transmit the data through a cooperative device. The above-described example can be equally applied to a case where a base station transmits data to a terminal, thereby achieving much better system performance. Hereinafter, a wireless communication system including a plurality of terminals having a cooperative system is referred to as a Multi Radio Access Technology (RAT) system.

A multi-radio access system can perform communication by using a single communication method or using a plurality of communication methods at the same time.

Here, the multi-radio access system can use Bluetooth, which is a type of short-range wireless communication. In particular, low-power Bluetooth beacon technology can be applied.

This low-power Bluetooth beacon technology uses a Bluetooth signal to allow a smart device located at a nearby location to recognize the beacon, provide various information to the smart device in the place where the beacon is installed, or receive the information from the smart device. It is a kind of wireless communication technology. More specifically, Apple's iBeacon function can be seen as a feature that enables Apple's smart devices to verify if the Bluetooth beacon signal matches the defined signaling scheme.

At this time, the communication with the smart device approaching to the vicinity of the beacon is a technology that is widely seen as a technology platform in which various business models can be expressed according to the type of information provided or the type of information received from the smart device .

However, the iBeacon function which is disclosed now discloses information about the signal contents of the Bluetooth beacon, which causes a problem that the connected Bluetooth beacon can be easily copied anywhere.

This problem becomes a big barrier in securing diversity of service model based on Bluetooth using Bluetooth.

For example, the cashable coupon provided only to a specific user who accesses the Bluetooth beacon may be an obstacle to utilization of the service model because the coupon can be issued even when a specific action of the user does not occur through copying of the beacon signal.

Therefore, there is a need for measures to solve such problems.

The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see an object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

There may be two or more display units 151 depending on the terminal or beacon device implementation. For example, in a terminal or a beacon device, a plurality of display portions may be disposed on one surface or may be disposed integrally, or may be disposed on different surfaces, respectively.

(Hereinafter, referred to as a 'touch screen') in which a display unit 151 and a sensor for sensing a touch operation (hereinafter, referred to as 'touch sensor') form a mutual layer structure, It can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like.

The proximity sensor 141 may be disposed in an inner region of a terminal or a beacon device to be wrapped by the touch screen or in the vicinity of the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays.

And to detect the proximity of the pointer by the change of the electric field along the proximity of the pointer when the touch screen is electrostatic. In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying occurrence of an event of the terminal or the beacon apparatus. Examples of events occurring in a terminal or a beacon device include receiving a call signal, receiving a message, inputting a key signal, and touch input. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 154 is vibration. The intensity and pattern of the vibration generated by the hit module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

In particular, the DLP module may be advantageous for miniaturization of the projector module 151 by enlarging and projecting an image generated by reflecting light generated from a light source on a DMD (Digital Micromirror Device) chip.

Preferably, the projector module 155 may be provided longitudinally on the side, front or back side of the terminal or beacon device. It goes without saying that the projector module 155 may be provided at any position of the terminal or the beacon device, if necessary.

The memory unit 160 may store a program for processing and controlling the control unit 180 and temporarily store the input / output data (e.g., telephone directory, message, audio, For example. The memory unit 160 may also store the frequency of use of each of the data (for example, each telephone number, each message, and frequency of use for each multimedia). In addition, the memory unit 160 may store data on vibration and sound of various patterns output when the touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM A disk, and / or an optical disk. The terminal or beacon device may operate in association with a web storage that performs the storage function of the memory 160 on the Internet.

The terminal or the beacon device may perform D2D (device-to-device) communication in a multi-radio access system.

D2D (device-to-device) communication refers to a technology that enables direct communication between devices in a mobile device.

A typical example is Bluetooth, and LTE D2D technology is emerging that enables LTE communication between telecommunication devices in close proximity. Unlike Bluetooth, which requires activation between devices for terminal communication and terminal authentication, LTE D2D can send and receive data at 75Mbps without base station. It is advantageous to be able to maintain communication even if the base station is stopped due to automatic connection, disaster, war and so on.

Here, a radio station which is opened on the shore for communication with a land mobile station or relay by a mobile relay station is referred to as a base station and may be referred to as a base station or an eNB. Next, the user terminal may be referred to as user equipment (UE).

In a device-to-device (D2D) communication in which a UE performs direct radio communication with another UE, that is, direct communication between the UEs, the eNB may transmit a scheduling message for instructing D2D transmission / reception. The UE participating in the D2D communication receives the D2D scheduling message from the eNB and performs a transmission / reception operation indicated by the D2D scheduling message. Here, the UE refers to a user terminal, but when a network entity such as an eNB transmits and receives signals according to a communication method between the UEs, the UE can also be regarded as a kind of UE. A link directly connected between UEs is referred to as a D2D link, and a link in which a UE communicates with an eNB is referred to as an NU link.

Meanwhile, a multi-radio access system can use Bluetooth, which is a type of short-range wireless communication, and in particular, low-power Bluetooth beacon technology can be applied.

This low-power Bluetooth beacon technology uses a Bluetooth signal to allow a smart device located at a nearby location to recognize the beacon, provide various information to the smart device in the place where the beacon is installed, or receive the information from the smart device. It is a kind of wireless communication technology. More specifically, Apple's iBeacon function can be seen as a feature that enables Apple's smart devices to verify if the Bluetooth beacon signal matches the defined signaling scheme.

2A to 2C are diagrams for explaining a low-power Bluetooth beacon and an apparatus according to the present invention.

Figure 2a shows the iBeacon technology published at WWDC 2013.

As shown in FIG. 2A, recently, Apple, which does not officially support NFC, disclosed a function called iBeacon while supporting low-power Bluetooth technology in iOS7, and the interest and related products of the technology are being exploded on the market explosively .

In addition, as shown in FIG. 2B, in the case of ShopKick and Sonic Notify, a marketing solution business for an offline store was performed using a non-audible frequency (ultrasound), and after the iBeacon function was disclosed, a Bluetooth beacon was used We are changing the technology from the same business model.

In other words, low-power Bluetooth beacon technology is expected to exploit in the near future because of its wide use, but companies that released major Bluetooth beacon products are Estimote (No. 1 market share), Kontakt, (Bluecats) Qualcomm (Gimbal products) and Paypal (Paypal) are the areas where overseas companies lead the technology.

Specifically, the communication with the smart device approaching the vicinity of the beacon is a technology platform in which various business models can be expressed according to the type of information to be provided or the type of information received from the smart device.

FIG. 2C shows a specific example of utilization of the beacon service. The low-power Bluetooth beacon technology includes a marketing model for attracting customers in the offline commerce area, a model for promoting or compensating products to customers entering the store, It can be used as an automatic payment or a model to automatically accumulate.

At this time, the security of the signal transmitted by the Bluetooth beacon is an essential technology to expand the application of the technology to the mobile payment market, which is expected to be the largest market among the users of the Bluetooth beacon technology.

 In other words, if the technology that enables the security of Bluetooth beacon signal to be reliable and low power is developed and the intellectual property right is secured, it will be possible to enter into the Bluetooth beacon market prevailed by foreign companies with stable and high competitive power, It is expected to be able to gain an advantage in the dispute with foreign companies that are anticipated.

However, the iBeacon function which is disclosed now discloses information about the signal contents of the Bluetooth beacon, which causes a problem that the connected Bluetooth beacon can be easily copied anywhere.

This problem becomes a big barrier in securing diversity of service model based on Bluetooth using Bluetooth.

For example, the cashable coupon provided only to a specific user who accesses the Bluetooth beacon may be an obstacle to utilization of the service model because the coupon can be issued even when a specific action of the user does not occur through copying of the beacon signal.

Therefore, in order to solve such a problem, the present invention intends to provide a method and apparatus for preventing copying of low-power Bluetooth low energy beacon based on Bluetooth 4.0 (BLE, Bluetooth Low Energy).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the present invention in detail, a multi-radio access system based on the contents of the present invention will be described in detail with reference to the drawings.

3 is a diagram illustrating an example of a multiple wireless access system using a low-power Bluetooth beacon signal in connection with the present invention.

Referring to FIG. 3, a multi-radio access system includes a base station 1100 and a plurality of communication devices 1110, 1120, 1130, and 1140.

In FIG. 3, devices 1110, 1120, 1130, and 1140 indicated as communication devices are connected to other communication devices and are connected to a source device, a source device A source device that does not act as a cooperative device or a cooperative device that acts as an intermediary to help the source device communicate with the base station. have.

In a multiple wireless access system, a plurality of communication devices 1110, 1120, 1130, and 1140 can establish cooperation systems with each other. In a multi-radio access system in which a cooperative system is established, a source device can transmit data to a base station together with a cooperative device. Furthermore, the Source Device may receive data from the base station along with a cooperative device.

Here, a direct wireless communication scheme between a plurality of devices may be different from a direct wireless communication scheme between the base station and a plurality of devices. That is, data is transmitted and received by applying a wireless LAN access method (for example, Bluetooth, Wi-Fi, etc.) between a plurality of devices, and a mobile communication network access method (for example, IEEE 802.16 WiMAX), etc.) can be applied to transmit and receive data.

For example, a plurality of devices can directly communicate with each other according to an IEEE 802.11 (Wi-Fi) technology scheme or a Bluetooth technology scheme. On the other hand, each of the plurality of devices may directly communicate with each other using IEEE 802.16 (WiMAX) technology.

However, the present invention is not limited thereto, and a base station and a plurality of devices can communicate with each other according to the same wireless communication scheme.

That is, data may be transmitted and received between a plurality of devices using a wireless LAN connection scheme (for example, Bluetooth, Wi-Fi, etc.), and a wireless LAN connection scheme may be applied between the base station and a plurality of devices. In addition, data is transmitted / received by applying a mobile communication network connection method (e.g., IEEE 802.16 (WiMAX)) between a plurality of devices, and a mobile communication network connection method is applied between the base station and a plurality of devices equally, .

In addition, a method in which a base station and a plurality of devices communicate with each other according to a wireless communication method may be referred to as an in-band communication method, an in-band signaling communication method, or the like.

Referring to FIG. 3, in a multi-radio access system in which a cooperative system is established, a source device 1140 can transmit data together with a cooperating device 1130 to a base station 1100. As a result, the communication device can efficiently transmit data, thereby ensuring excellent performance. In addition, the throughput of each device can be enhanced through the multi-radio access system in which the cooperative system is established, and the effect of reducing the power consumption through the data communication through the cooperative system is also guaranteed.

Also, in a multi-radio access system in which a cooperative system is established, a source device can transmit data to a base station through a cooperative device. Furthermore, the Source Device may receive data from the base station via a cooperative device.

Referring to FIG. 3, in a multi-radio access system in which a cooperative system is established, a source device 1110 can transmit data to a base station 1100 through a cooperating device 1120. This allows the communication device to efficiently transmit data, thereby preventing deterioration of system performance.

Although FIG. 3 illustrates an example in which the source device transmits data to the base station through the cooperating device, the above description may be applied to the case where the base station receives data from the source device.

3 may be a cooperating device or a neighboring device not participating in the transmission of data, and the cooperating devices 1120 and 1130 may also be a source device or data Lt; RTI ID = 0.0 > of < / RTI >

3, it is assumed that the object for transmitting data is the base station 1100. However, the present invention is not limited thereto, and the role of the base station 1100 is not limited to the other terminals 1110, 1120, 1130, 1140, A beacon device may be substituted.

4 is a diagram illustrating an example of the operation of a multiple wireless access system using a low-power Bluetooth beacon signal in connection with the present invention.

Referring to FIG. 4, a multi-radio access system includes a base station 210 and a plurality of communication devices 220 and 230.

In the multiple wireless access system, a plurality of communication devices 220 and 230 can establish cooperative systems with each other through a wireless technology such as 802.11 (Wi-Fi).

Each of the plurality of communication devices 220 and 230 may transmit or receive data directly via the base station 210 and a wireless technology such as IEEE 802.16 (WiMAX).

At this time, if the current communication quality of the source device 220 suddenly drops, the source device 220 can indirectly transmit the data to the base station 210 through the cooperation device 230. In addition, the source device 220 may indirectly receive data from the base station 210 via the collaboration device 230.

Accordingly, in a multi-radio access system, a communication device can directly communicate data directly with a base station, indirectly communicate with the help of a cooperative device having excellent communication quality, Deterioration can be prevented and efficient data communication can be performed.

In a multi-radio access system, in order for a plurality of communication devices to cooperate with each other to transmit and receive data, a preliminary procedure for exchanging information in advance is required.

In the multi-radio access system, information exchange steps to be performed between a base station and a plurality of communication devices can be roughly classified into four steps. That is, it may include a general network entry step, a negotiation step for cooperation of a plurality of devices, a search for a neighboring device of the source device, a selection of a cooperating device among the discovered neighboring devices, and a connection to the selected cooperating device .

Meanwhile, in a multi-radio access system, a method in which a plurality of communication devices communicate with each other in cooperation may be classified into an infrastructure basic service set (BBS) and an independent basic service And an independent BBS (Basic Service Set).

An access point (AP) means a connection point between a base station and a plurality of terminals in a multi-radio access system, and may be referred to as an interconnection point. For example, an access point (AP) .

An access point may be referred to as an access point, an access point, an AP, or the like, but is referred to as an access point in this specification for convenience of explanation.

When an access point (AP) is used in a multi-radio access system, a point-to-point function for connecting terminals located at two points to each other for mutual communication can be provided.

Also, unlike the point-to-point function, a point-to-multipoint function that allows a plurality of connected terminals to communicate with each other by connecting a plurality of terminals at the same time may be provided.

 In addition, it may provide a repeater function for extending data communication to a wireless area by being wirelessly connected to a base station and another access point (AP). That is, an access point (AP) set as a repeater can communicate with another access point (AP) while providing a connection with the base station.

In addition, a wireless client ( Wireless) which is connected to a plurality of terminals capable of exchanging signals with a wired or near-field communication network, Client ) function may be provided.

4, it is assumed that the object for transmitting data is the base station 210. However, the present invention is not limited to this, and the role of the base station 210 is not limited to the other terminals 220 and 230, You may.

5 is a diagram showing a concrete example of a basic service set (BSS) according to whether or not a beacon device is used as an access point (AP) in the context of the present invention.

5 (a) shows an example of an Infrastructure Basic Service Set (Infrastructure BBS).

In an Infrastructure Basic Service Set (BBS), a plurality of terminals perform communication using access points (APs).

The multiple wireless access system may include a plurality of access points (APs), and a plurality of terminals may exist around each of the plurality of access points.

The operation for client cooperation under the Infrastructure Basic Service Set (BBS) structure will be described in more detail with reference to FIG.

FIG. 6 is a diagram illustrating an example in which a base station and a terminal transmit and receive data in a multi-radio access system using an access point (AP) as an access point (AP) according to the present invention.

Referring to FIG. 6, a first access point 1150 and a second access point 1160 are included in a multiple radio access system.

A first terminal 1110 and a second terminal 1120 exist in the vicinity of the first access point 1150. The first terminal 1110 and the second terminal 1120 communicate with the base station 1100 through a client cooperation And perform a data communication operation for Client Cooperation.

A third terminal 1130 and a fourth terminal 1140 exist in the vicinity of the second access point 1160. These third terminal 1130 and fourth terminal 1140 communicate with the base station 100 And perform a data communication operation for Client Cooperation.

The foregoing includes both cases where a plurality of terminals are located within the coverage of each of a plurality of access points, connected wirelessly, or detected within a coverage area. That is, when the terminal and the access point are correlated, an Infrastructure Basic Service Set (BBS) can be implemented.

Returning to Fig. 5, Fig. 5 (b) shows an example of an Independent BBS.

An independent basic service set (Independent BBS)), a plurality of terminals are directly connected to each other.

For convenience of explanation, it is assumed that a plurality of terminals are directly connected to each other to constitute an independent basic service set (BBS). However, this is merely an example and the present invention is not limited thereto.

Hereinafter, a method and an apparatus for transmitting and receiving data using a low-power Bluetooth beacon in a wireless communication system proposed by the present invention will be described based on the above-described communication method and devices.

The system proposed by the present invention may include a terminal 410, a server or a mother beacon 420 and a child beacon 430.

Basically, the terminal 410, the server or the mother beacon 420 and the child beacon 430 may include at least some of the configurations described in FIG. 1 or all of the configurations described with reference to FIG.

In addition, the server or mother beacon 420 may alternatively be present.

In addition, the terminal 410, the server or the mother beacon 420 and the child beacon 430 may exist in plural.

Wired communication and / or wireless communication may be applied between the terminal 410, the server or the mother beacon 420 and the child beacon 430. [

That is, a communication scheme applicable to the above-described multiple access system can be applied, and examples thereof include a code division multiple access (CDMA) system, a frequency division multiple access (FDMA) system, a time division multiple access (TDMA) system, an orthogonal frequency division multiple access (SC-FDMA) system, and a multi-carrier frequency division multiple access (MC-FDMA) system.

In addition, the server or mother beacon 420 and child beacon 430 may transmit and / or receive beacon signals. At this time, the beacon signal may be referred to as a discovery signal.

That is, in order to perform the above-described D2D operation, the UE performs a discovery process to determine whether the UE to which the UE desires to perform D2D communication is located in a neighboring area where D2D communication is possible.

In this discovery process, each UE transmits a unique discovery signal for identifying itself, and when the neighboring UE detects this, it is determined that the UE that transmitted the discovery signal is located at an adjacent position.

Each UE performs a D2D communication to transmit / receive actual user data after confirming whether a counterpart UE to which the UE desires to perform D2D communication exists at a neighboring position through a discovery process.

Such a discovery signal may include various signals defined for existing cellular communication, for example, DM-RS for PRACH preamble or PUSCH demodulation in the 3GPP LTE system, or SRS transmitted by the UE for acquiring CSI (channel state information) Reuse, or use new types of signals that are more optimized for discovery purposes.

A heterogeneous network in which different communication methods are applied may be formed between the terminal 410, the server or the mother beacon 420 and the child beacon 430, and a plurality of child beacons 430 may form a network can do.

Fig. 7 shows an example in which a plurality of beacon devices applied to the present invention form a heterogeneous network.

Referring to FIG. 7, a child device corresponding to a child beacon 430 and a server or a mother beacon 420 is shown based on a management system (application).

In addition, an ANT network, a TCP / IP, a Bluetooth communication method, and the like can be used in combination between the devices shown in FIG.

Here, ANT is one of the near-field wireless sensor network technologies such as ZigBee and Bluetooth, and supports radio protocol. It is characterized by low operation overhead, low efficiency, and low power consumption.

Through protocol simplification, it is possible to operate with low cpu overload, and as a result, it can operate with lower power.

In addition, ANT does not require frequent charging when applied to mobile personal monitoring, so it can improve the performance.

Features of ANT include ultra low power, simplicity (small stack size), scalability (complex network top polo supporter), and flexible network topology.

Next, ANT application areas include sports fitness and cycle performance monitoring, and Garmin and Nike have applied ANT technology to their performance monitoring products.

In addition, ANT's power efficiency is suitable and practical because of its low battery consumption and cost in many applications requiring wireless connectivity.

Examples of ANT applications include wrist measurement systems, heart rate monitoring (HRM), speed and distance monitoring (SDM), bicycle computers, health and health monitoring devices, industrial sensors, RFID, location-based services, and utility radio meter reading (AMR).

Meanwhile, FIG. 8 shows a specific example in which a plurality of beacon devices applied to the present invention form a heterogeneous network.

Referring to FIG. 8, a mesh network using a hub device as a coordinator is shown.

Here, a new beacon can be automatically added to the Beacon Network.

Also, network communication is possible through the ANT network.

Referring to FIG. 8, the number of MAX beacons is 64, and a maximum of 6 network connections is possible for each child beacon.

However, this is merely an embodiment of the present invention, and the contents of the present invention are not limited thereto.

Fig. 9 shows another specific example in which a plurality of beacon devices applied to the present invention form a heterogeneous network.

FIG. 9 shows a method using OTA firmware update.

Referring to FIG. 9, there is shown a network structure for performing a firmware update through a management application in order to solve a shortage of memory space and error tracking and recovery of a commercial chip, which is a problem in firmware update of a beacon network through a hub device .

That is, since the firmware update is performed after recognizing the peripheral beacon, the above-described problem can be solved.

Based on the above-described communication method and heterogeneous network applied between the terminal 410, the server or the mother beacon 420 and the child beacon 430, the low power (low power) Describes a method for preventing copying of a Bluetooth beacon (Bluetooth low energy beacon).

The method for preventing duplication of the low-power Bluetooth beacon proposed by the present invention can be roughly divided into two methods.

(1) Method 1: A method in which a child beacon 430 or a mother beacon 420 changes information after receiving an authentication start request from the user terminal 410

(2) Second method: a method in which the child beacon 430 periodically changes information

In addition, the first method may be divided into a 1-1 method and a 1-2 method.

(1) Method 1-1: How a signal change occurs in a beacon

(2) Method 1-2: How changes in signal occur in child beacons

Hereinafter, each method will be described in detail with reference to the drawings.

First Method

The first method proposed by the present invention is a method of changing the information of the child beacon 430 after the server or the mother beacon 420 receives the authentication start request from the user terminal 410.

10 illustrates an example of a first method for preventing copying of a low-power Bluetooth beacon based on Bluetooth 4.0 in connection with the present invention.

The first method, which will be described later, can be divided into two methods depending on the subject performing the change to the signal.

That is, the main beacon 420 may be divided into (1-1 method) and the child beacon 430 (1-2 method).

The 1-1 method in which the mother beacon 420 is the entity that performs the signal change in advance for authentication will be described.

Method 1-1

In FIG. 10, the server or mother beacon 420 provides a function of controlling the child beacon 430. Further, the server or mother beacon 420 may serve as an authentication server.

Referring to FIG. 10, the terminal 410 may first transmit authentication start request information to the server or the mother beacon 420 (S1100).

Wherein the authentication initiation request may be communicated over a network and / or near-field communication.

In step S1100, the terminal 410 generates p, which is a unique identifier that can identify itself, and transmits the generated p to the server or the mother beacon 420 side.

When the server or the mother beacon 420 receives the authentication start request information, the server or the mother beacon 420 changes the identifier information transmitted by the terminal and transmits the changed signal to the child beacon 430 side (S1200).

That is, in the method 1-1, the entity that changes the identifier information transmitted by the terminal is the server or the mother beacon 420. [

Meanwhile, in step S1200, the information work currently being transmitted by the child beacon 430 is interrupted, and command information for transmitting the changed identifier information received by the child beacon 430 to the terminal 410 through step S1200 is transmitted as identification information Can be transmitted together.

That is, the information transmitted to the child beacon 430 is changed to p 'in which the p received by the server or the mother beacon 420 is changed in step S1100 and information that the server or the mother beacon 420 commands the child beacon 430 q value.

That is, the server or the mother beacon 420 transmits the signal r, in which p 'and q are combined, to the child beacon 430.

Where the signal r can be used as a specific seed value and is mainly used as a timestamp or counter.

Thereafter, the child beacon 430 performs a process of stopping the operation of transmitting the current information according to the q value (S1300).

That is, the child beacon 430 extracts a major, a minor, or a name from the received signal r value, stops transmission of the current information according to the q value, and stores p ' .

However, the step S1300 is not essential and the signal r received by the child beacon 430 may be used as it is.

Thereafter, the child beacon 430 may transmit p 'changed in step S1200 to the terminal 410 (S1400).

After that, the terminal 410 may request authentication to the server or the mother beacon 420 side including the signal p 'received from the child beacon 430 (S1500).

At this time, the server or mother beacon 420 performs authentication using p 'included in the information transmitted by the terminal 410.

Herein, the received signal is processed in the server or the mother beacon 420 according to need, for example, a method of using a standard, a symmetric key / asymmetric key (public key) for covering the signal r with a cap, or the like can be used . Also, a method provided as a Bluetooth standard may be applied.

That is, the server or the mother beacon 420 performs the authentication using the information received from the terminal 410 (S1600), and determines whether to perform the predetermined job according to the authentication or not (S1700).

At this time, the server or mother beacon 420 may be divided into a first mother beacon and a second mother beacon.

First, the first mother beacon plays a role of transmitting a predetermined protocol.

In addition, the second mother beacon may change the identifier information to the first information according to a predetermined protocol transmitted from the first mother beacon, and may transmit the changed first information to the child beacon 430.

16A and 16B are comparative diagrams for explaining a specific form of the mother beacon according to the present invention.

16A shows a structure proposed by the existing invention, and FIG. 16B shows a structure proposed by the present invention.

16A and 16B, H denotes a hash value, I denotes actual information (for example, a store ID), and N denotes Nonce.

Referring to FIG. 16B, the MB may be composed of a portion A that performs an actual authentication function, and a T that generates a nonce and generates a nonce. Here, A sends a key to T, T uses key to generate N at a certain time, and H and N to transmit to CB (child beacon).

In addition, the CB plays a role of broadcasting the received H as a beacon signal, and T is connected to the CB by a wired or wireless connection to form a network (that is, T and CB can be the same entity).

Also, the beacon signal includes H or H ', and H' is information converted by a protocol commonly known by A and T, and info is not included

Therefore, the present invention disclosed in FIG. 16B is advantageous in that the information necessary for security enhancement is not known to the outside as plain text.

In contrast, in the prior art disclosed in FIG. 16A, when a handset can not establish a network, a secure identifier is stored in a handset, and authentication is performed when the handset becomes online later (it is described that the validity period can be extended, ).

This prior art means that Nonse disclosed as broadcast in off-line authentication is time-based, which means that there is a drawback that it is very vulnerable to security attacks through time modulation.

That is, in the invention of the present application, Nonce is shared only in MB (A, T), which means that attack through time modulation becomes difficult.

As a result, in the case of the model for authenticating via the server, the hash for authenticating info and nonce is transmitted to the server in the model according to the prior art, whereas only the hash is transmitted in the model proposed by the present application, Which means that it provides a much stronger effect.

Method 1-2

As described above, in FIG. 10, the server or mother beacon 420 provides the function of controlling the child beacon 430. FIG. Further, the server or mother beacon 420 may serve as an authentication server.

Referring to FIG. 10, the terminal 410 may first transmit authentication start request information to the server or the mother beacon 420 (S1100).

Wherein the authentication initiation request may be communicated over a network and / or near-field communication.

In step S1100, the terminal 410 generates p, which is a unique identifier that can identify itself, and transmits the generated p to the server or the mother beacon 420 side.

When the server or the mother beacon 420 receives the authentication start request information from the server or the mother beacon 420, the server or the mother beacon 420 may transmit the received information and information for changing the signal as a child beacon (S1200).

Here, the information for signal modification can be used as a specific seed value, and is mainly used as a timestamp or a counter.

Thereafter, the child beacon 430 changes the received change signal again (S1300).

That is, the child beacon modifies the identifier information based on the information for signal change received from the server or the mother beacon 420 to generate new information.

Therefore, unlike the method 1-1, the subject who changes the identifier information transmitted by the user becomes the child beacon 430 in the 1-2 method.

Thereafter, the child beacon 430 may transmit the changed signal to the terminal 410 (S1400).

After that, the terminal 410 can request authentication to the server or the mother beacon 420 side including the signal received from the child beacon 430 (S1500).

At this time, the server or the mother beacon 420 can determine whether or not the terminal 410 is authenticated using the identifier information in step S1200, the information for changing the signal, and the information received from the terminal 410 in step S1500 (S1600).

Herein, the received signal is processed in the server or the mother beacon 420 according to need, for example, a method of using a standard, a symmetric key / asymmetric key (public key) for covering the signal r with a cap, or the like can be used . Also, a method provided as a Bluetooth standard may be applied.

That is, the server or the mother beacon 420 performs the authentication using the information received from the terminal 410 (S1600), and determines whether to perform the predetermined job according to the authentication or not (S1700).

Meanwhile, when an RTC (Real-Time Clock) module is inserted in the child beacon 430, a problem that the price is excessively increased may occur. Therefore, a method (1 time / hr) in which the RTC module is inserted into the server or the mother beacon 420 and corrected by the network connection can be used.

On the other hand, at least some of the child beacon 430 and the server or the mother beacon 420 may change the signal in two ways.

That is, a method of setting a valid signal only for a predetermined time and a method of requesting a seed value using a hash function, for example, may be used.

FIG. 11 is a diagram for explaining a method for preventing copying of a low-power Bluetooth beacon through a time difference transmission with a cycle according to the present invention. FIG. 12 is a flowchart illustrating an authentication process And is a diagram for explaining a method for preventing copying of a low-power Bluetooth beacon.

FIG. 11 shows the contents of One-Chip Solution Bluetooth Advertising, which is a method of setting UUID, Major, Minor data, signal strength, and signal period.

For example, a plurality of data can be transmitted with a time difference of one second.

Also, FIG. 12 shows copy protection authentication (an authentication process by a separate SDK).

12, a method of transmitting additional authentication information in a beacon and authenticating the terminal through a separate SDK is applied.

10, a method in which a server or mother beacon 420 holds multiple OPT seeds and transmits a different seed for each child beacon 430 can be used.

In addition, a method of allowing a plurality of terminals 410 as an OPT even if the user requests authentication may be applied.

Specifically, 1: 1 authentication and 1: N authentication may be applied to the communication between the server or the mother beacon 420 and the child beacon 430 as an authentication method.

First, 1: N authentication refers to a scheme in which an OTP is shared by all persons near the child beacon 430 in the same OTP manner. This method is preferably used when it is intended to detect existence.

Next, 1: 1 authentication is a method in which a single user uses an OTP received from the same area (one or more child beacons 430). This approach can provide a higher level of security, so it is desirable to use it for cash rewards (for example, coupons, vouchers, etc.).

Meanwhile, the child beacon 430 may be used as a device for providing a basic function for acquiring position information, or as a device for realizing position information authentication in the form of a power source, an antenna, and a wireless router.

In addition, as described above, a method of extracting a major, minor, or name may be used as a method of changing the signal of the child beacon 430.

Second Method

The second method proposed by the present invention is a method in which the child beacon 430 periodically changes information.

Figure 13 illustrates an example of a method for preventing copying of a low power Bluetooth beacon based on Bluetooth 4.0 in connection with the present invention.

In FIG. 13, the server or the mother beacon 420 provides a function of controlling the child beacon 430. Further, the server or mother beacon 420 may serve as an authentication server.

Referring to FIG. 13, the child beacon 430 periodically modifies the signal (S2100).

As described above with reference to FIGS. 11 and 12, in step S2100, a method of setting a valid signal only for a predetermined period of time and a method of requesting a seed value using a hash function, for example, may be used.

Next, the terminal 410 receives the periodically changed signal (S2200).

After that, the terminal 410 may request authentication to the server or the mother beacon 420 side including the signal received from the child beacon 430 (S2300).

At this time, the server or the mother beacon 420 performs authentication using at least a part of the information transmitted by the terminal 410, and processes the received signal in the server or the mother beacon 420 according to need, a standard using a cap, a method using a symmetric key / asymmetric key (public key), and the like can be used. Also, a method provided as a Bluetooth standard may be applied.

Thereafter, the server or the mother beacon 420 performs authentication using the information received from the terminal 410 (S2400), and whether to perform the predetermined operation is determined according to whether or not the authentication is performed (S2500).

On the other hand, the use of the symmetric key / asymmetric key (public key) has a conspicuous point.

First, in the case of the symmetric key algorithm, a simple arithmetic operation is used because the keys for encryption and restoration are the same.

Specifically, the symmetric key algorithm is faster than the asymmetric key, and the algorithm is not as complicated as the asymmetric key. On the other hand, the symmetric key algorithm has a disadvantage that key synchronization is required and a problem arises when key value is leaked no matter how strong the encryption algorithm is.

There are two types of symmetric key algorithms: (1) Pre-shared (symmetric), but there are other ways to use appointments in advance, such as faxing or telephone. In addition, SSHv1 uses the hybrid encryption packaging method, but it is vulnerable to MITM. Another method is the Diffie Hellman method. This method uses a seed value, which means that the key is completely different so that the attacker can not decipher and provides strong security.

Next, in the case of the public key (asymmetric key) algorithm, the keys used for encryption and restoration are different from each other, and a difficult arithmetic operation is used.

This public-key (asymmetric-key) algorithm has the advantage of less key synchronization problems, but has the disadvantage of being slow and vulnerable to Man-In-The-Middle attacks.

These public key algorithms require two keys: a private key (a key known only to me) and a public key (a key that many people can know and take)

These two keys are complementary to each other. If they are encrypted with a private key, they can be decrypted with a public key. If they are encrypted with a public key, they can be decrypted with a private key. However, public key can not be decrypted with public key, and private key can not be decrypted with private key.

The second method is preferably discarded when the private key is exposed.

Meanwhile, FIG. 14 is a diagram for explaining an example in which each device performs communication after position authentication based on the method described in FIG.

Each of the steps described in Fig. 14 corresponds to the steps described in Fig. 10, except that the step of entering the specific place by the terminal 410 first proceeds first.

The scenario to which the step of FIG. 10 is applied after the location authentication described with reference to FIG. 14 can be applied to an office attendance management method, a method of issuing mileage or cash coupons at a store, a mobile payment method at a store, or a door lock of a home network.

15 is a diagram for explaining an example in which each device performs communication after position authentication based on the method described in Fig.

Each of the steps described in FIG. 15 corresponds to the step described in FIG. 13, except that the step of entering the specific place by the terminal 410 proceeds first.

The scenario in which the step of FIG. 13 is applied after the position authentication described in FIG. 15 is performed in the case of authenticating the position in the movie theater, authenticating the user at the entrance to the auditorium, authenticating the venue in the sports arena, It can be utilized for authentication and the like.

As described above, the currently disclosed iBeacon function discloses information about the signal content of the Bluetooth beacon, which causes a problem that the connected Bluetooth beacon can be easily copied anywhere.
