In detail, step S360 is performed by the portable tracking device 120 receiving an authentication request message including E (D_Key + part_PID, D_Key) from the attachment device 110. Here, E (D_Key + sub_PID, D_Key) means a ciphertext obtained by encrypting the D_Key and the sub_PID which is the PID of the attachment device 110 with the D_Key.

In operation S370, the portable tracking device 120 1) decrypts E (D_Key + sub_PID, D_Key) contained in the authentication request message received by the D_Key owned by the portable tracking device 120 to obtain D_Key and sub_PID. Later, 2) it is determined whether the 'D_Key' obtained by decryption is the same as 'D_Key owned by itself', and 3) 'sub_PID obtained by decryption' and 'minor_PID stored in step S340' and By judging whether they are the same.

If the legitimate attachment device 110 is authenticated, the portable tracking device 120 transmits an authentication completion message to the attachment device 110 (S380).

In more detail, step S380, the portable tracking device 120 transmits an authentication completion message including E (authentication_Key + 3PIDs, D_Key) to the attachment device 110. Here, E (authentication_Key + 3PIDs, D_Key) means an encrypted text obtained by encrypting authentication_Key and 3PIDs with D_Key.

The attachment device 110 having received the authentication completion message decrypts and stores the authentication completion message (S390).

Specifically, in step S390, the attachment device 110 1) decrypts E (authentication_Key + 3PIDs, D_Key) contained in the authentication completion message received by D_Key to obtain authentication_Key and 3PIDs, and 2) obtains it. The process of storing authentication_Key and 3PIDs.

The stored authentication key may be used to encrypt the information that the attachment device 110 transmits to the outside. Here, ARIA encryption may be used as the encryption.

3PIDs may be used as addresses of the attachment device 110, the portable tracking device 120, and the house monitoring device 130.

Thereafter, the attachment device 110 vibrates three times for three seconds to inform that the authentication is completed (S400). As a result, the probation officer and the specific target may know that the authentication of the attachment device 110 is completed.

The reason for notifying that the authentication is completed by vibrating rather than displaying guide text on the LCD like the portable tracking device 120 is because the LCD 110 is not provided in the attachment device 110. Therefore, if the LCD is provided in the attachment device 110, it is also possible to inform that the authentication is completed through the LCD.

Authentication of the attachment device 110 and the portable tracking device 120 described so far is made without intervention of the house monitoring device 130. This means that the authentication of the attachment device 110 and the portable tracking device 120 does not have to be made in the house of a specific target. That is, there is no restriction of the place where the authentication of the attachment device 110 and the portable tracking device 120 should be made.

2) Authentication process of house monitoring device 130

4 is a view provided to explain the authentication procedure of the house monitoring device 130.

When power is supplied to the house monitor 130, the house monitor 130 checks whether authentication_Key is stored. In this embodiment, only the D_Key is stored in the house monitoring device 130, and the authentication_Key is not stored.

When it is confirmed that the authentication_Key is not stored as described above, the house monitoring apparatus 130 requests the authentication to the control center server 180 (S410).

In more detail, step S410, the house monitor 130 transmits the authentication request message containing E (D_Key + _PID, D_Key) to the control center server 180. Here, E (D_Key + ga_PID, D_Key) means a cipher text that encrypts D_Key and temporary_PID, which is the PID of the house monitoring apparatus 130, with D_Key.

The control center server 180 receiving the authentication request message authenticates the house monitoring apparatus 130 that transmits the authentication request message (S420).

In detail, in step S420, the control center server 180 1) decrypts E (D_Key + _PID, D_Key) contained in the authentication request message received by the D_Key owned to obtain D_Key and provisional_PID. After that, 2) it is determined whether the 'D_Key obtained by decryption' is the same as 'D_Key owned by itself', and 3) 'a_PID' obtained by decryption is 'a_PID registered by itself'. By the process of determining whether or not equal to.

If the legitimate house monitoring device 130 is authenticated, the control center server 180 transmits an authentication completion message to the house monitoring device 130 (S430).

In detail, in step S430, the control center server 180 transmits an authentication completion message including E (authentication_Key + 3PIDs, D_Key) to the house monitoring apparatus 130. Here, E (authentication_Key + 3PIDs, D_Key) means an encrypted text obtained by encrypting authentication_Key and 3PIDs with D_Key.

The house monitoring apparatus 130 having received the authentication completion message decrypts and stores the authentication completion message (S440).

Specifically, in step S440, 2) obtain the authentication_Key and 3PIDs by decrypting E (authentication_Key + 3PIDs, D_Key) contained in the authentication completion message received by the house monitoring apparatus 1) with D_Key. The stored authentication_Key and 3PIDs are stored.

The stored authentication key may be used to encrypt the information to be transmitted to the house monitoring device 130. Here, ARIA encryption may be used as the encryption.

Thereafter, the house monitoring apparatus 130 displays a phrase on the LCD to guide the authentication is completed (S450). As a result, the probation officer and the specific target may know that authentication of the house monitoring apparatus 130 is completed.

2. 감시 모드의 설정2. Setting the monitoring mode

When the registration / authentication procedure described so far is completed, the electronic supervision system will perform monitoring / supervision of a specific target in earnest.

On the other hand, the attachment device 110 is provided with a power saving function for reducing power consumption. Thus, attachment device 110 periodically switches between sleep mode and wake-up mode. The sleep mode and the wake-up mode relate to the operation mode of the attachment device 110, and it should be noted that the concept is different from the monitoring mode of the electronic supervision system to be described below.

(1) Types of monitoring mode

The monitoring mode is divided into 1) an external monitoring mode and 2) a house monitoring mode.

1) External monitoring mode

The external monitoring mode is a mode in which the specific object is sufficiently separated from the house to track the position of the specific object using the portable tracking device 120. In the external monitoring mode, the communication between the house monitoring device 130 and the attachment device 110 is disconnected. This is because the specific object to which the attachment device 110 is fastened and the location of the house where the house monitoring device 130 is installed are sufficiently spaced apart. On the other hand, the communication between the portable tracking device 120 and the attachment device 110 is maintained, because the specific object to which the attachment device 110 is fastened is carrying the portable tracking device 120.

5 is a view provided to explain the communication process of the portable tracking device 120 and the attachment device 110 in the external monitoring mode. As shown in FIG. 5, when the attachment device 110 wakes up (S510), it broadcasts a polling message (S520).

The pollng message contains sub-PID and status information indicating the status of the attachment device 110. Here, the status information includes the current monitoring mode, battery status, communication status, and the like.

The polling message broadcast in step S520 is received by the portable tracking device 120.

The portable tracking device 120 receiving the polling message broadcasts a reception response (S530). The reception response contains Hugh_PID.

In operation S530, the reception response broadcast by the portable tracking device 120 is received by the attachment device 110.

The attachment device 110 receiving the reception response switches to the sleep mode (S540). Thereafter, the attachment device 110 maintains the sleep mode, and when a predetermined period (for example, 10 seconds) elapses, the attachment device 110 switches to the wake-up mode and re-performs step S510.

On the other hand, the portable tracking device 120 transmits the state information and its own state information of the attachment device 110 contained in the polling message received in step S520 to the communication server 170 (S550). Thereafter, the communication server 170 receiving the status information transmits the received response to the portable tracking device 120 (S560).

Communication between the portable tracking device 120 and the communication server 170 is made through the relay of the 'mobile communication network 150 ↔ M2M server 160'. In addition, in the other procedures described below, communication between the two is performed through such a relay.

Thereafter, the state information transmitted to the communication server 170 is transmitted to the control center server 180 at the request of the control center server 180.

Meanwhile, like steps S510 to S540, steps S550 and S560 may also be performed periodically. In this case, the periods of both may not be the same and may be implemented differently. That is, the execution cycle of steps S550 and S560 may be longer than the execution cycle of steps S510 to S540.

2) House monitoring mode

The house monitoring mode is a mode in which a specific object is located in the house and thus the position of the specific object is determined using the location information of the house monitoring apparatus 130. In the house monitoring mode, the attachment device 110 may communicate with both the portable tracking device 120 and the house monitoring device 130, but maintain only communication with the house monitoring device 130.

6 is a view provided to explain the communication process between the house monitoring device 130 and the attachment device 110 in the house monitoring mode. As shown in FIG. 6, when the house monitor 130 wakes up (S610), it broadcasts a polling message (S620).

The polling message broadcast in step S620 is received by both the portable tracking device 120 and the house monitoring device (130). In the house monitoring mode, the portable tracking device 120 that receives the polling message does not respond.

However, the house monitor 130 receiving the polling message broadcasts the reception response (S630). The receipt response contains a pseudo_PID.

In step S630, the reception response broadcasted by the house monitoring apparatus 130 is received by the attachment device 110.

The attachment device 110 receiving the reception response switches to the sleep mode (S640). Thereafter, the attachment device 110 maintains the sleep mode, and when a predetermined period (for example, 10 seconds) elapses, the attachment device 110 switches to the wake-up mode and re-executes step S610.

On the other hand, the house monitor 130 transmits the status information and its own status information of the attachment device 110 contained in the polling message received in step S620 to the communication server 170 (S650). Thereafter, the communication server 170 receiving the status information transmits the reception response to the house monitoring apparatus 130 (S660).

Communication between the house monitoring device 130 and the communication server 170 is made through the relay of the 'mobile communication network 150 ↔ M2M server 160'. In addition, in the other procedures described below, communication between the two is performed through such a relay.

Meanwhile, like steps S610 to S640, steps S650 and S660 may also be performed periodically. In this case, the periods of both may not be the same and may be implemented differently. That is, the execution cycle of steps S650 and S660 may be longer than the execution cycle of steps S610 to S640.

(2) switching the monitoring mode

The change of the monitoring mode occurs when a specific object is 1) sufficiently spaced from the house and returned to the house, or 2) stays in the house and is sufficiently spaced from the house.

In the case of "1)", the switching from the external monitoring mode to the house monitoring mode is performed. In the case of "2)", the switching from the house monitoring mode to the external monitoring mode is performed. In the following, it will be described in detail one by one.

1) External monitoring mode → house monitoring mode

7 is a view provided to explain the process of switching from the external monitoring mode to the house monitoring mode. The process of switching from the external monitoring mode to the house monitoring mode may be understood as a process in which the attachment device 110 is handed over from the portable tracking device 120 to the house monitoring device 130.

As shown in FIG. 7, first, the attachment device 110 wakes up (S710) and broadcasts a polling message (S715).

The polling message broadcast in step S715 is received by both the portable tracking device 120 and the house monitoring device 130. Since the current location of the attachment device 110 fastened to a specific target is within the house, the polling message broadcast by the attachment device 110 can receive not only the portable tracking device 120 but also the house monitoring device 130. to be.

When the current monitoring mode is the external monitoring mode, the house monitoring apparatus 130 does not broadcast a response to the reception even if it receives a polling message.

However, the portable tracking device 120 receiving the polling message broadcasts the reception response (S720). In step S720, the reception response receives not only the attachment device 110 but also the house monitoring device 130.

The attachment device 110 receiving the reception response switches its operation mode to the sleep mode (S725).

On the other hand, the house monitor 130 receives the reception response transmits a mode switch request message to the portable tracking device (120) (S730). The mode switch request message transmitted in step S730 includes a content of requesting to switch the monitoring mode of the electronic supervisory system from the external monitoring mode to the house monitoring mode.

The portable tracking device 120 that receives the mode change request message from the house monitoring device 130 switches its operation mode to the monitoring release mode (S735). Then, the portable tracking device 120 transmits a switch completion response to the house monitor 130 (S740).

The portable tracking device 120 that receives the conversion completion response from the house monitoring device 130 switches its operation mode to the monitoring mode (S745).

Accordingly, the monitoring mode of the electronic supervision system is switched to the house monitoring mode. In this case, the house monitoring apparatus 130 may notify the control center 180 that the monitoring mode of the electronic supervision system has been switched to the house monitoring mode.

Thereafter, the attachment device 110 wakes up again (S750) and broadcasts a polling message again (S755).

The polling message broadcast in step S755 is received by both the portable tracking device 120 and the house monitoring device 130. The portable tracking device 120 switched to the monitoring release mode in step S735 does not broadcast a response to the polling message.

Instead, the house monitoring apparatus 130 switched to the monitoring mode in step S745 broadcasts a reception response to the polling message (S760).

The reception response broadcast in step S760 is received by both the attachment device 110 and the portable tracking device 120, the portable tracking device 120 does not respond to this.

However, the attachment device 110 recognizing that the reception response is received from the house monitoring device 130 rather than the portable tracking device 120 changes its monitoring mode from the external monitoring mode to the house monitoring mode (S765). Then, the attachment device 110 switches its operation mode to the sleep mode (S770).

2) House monitoring mode → external monitoring mode

8 is a view provided to explain the process of switching from the house monitoring mode to the external monitoring mode. The process of switching from the home monitoring mode to the external monitoring mode may be understood as a process of attaching the attachment device 110 to the portable tracking device 120 from the home monitoring device 130.

As shown in FIG. 8, the attachment device 110 first wakes up (S810) and broadcasts a polling message (S815).

The polling message broadcast in step S815 can be received only by the portable tracking device (120). Since the current position of the attachment device 110 fastened to the specific object is sufficiently spaced apart from the house, the house monitoring device 130 may not receive this polling message.

In addition, since the operation mode of the portable tracking device 120 is the unmonitored mode, the portable tracking device 120 does not respond to the polling message received in step S815.

The attachment device 110 may not receive any reception response to the polling message broadcast in step S815. Then, the attachment device 110 broadcasts the polling message once more (S820).

However, the attachment device 110 does not receive any response. Then, the attachment device 110 broadcasts the polling message once more (S825), but does not receive any response thereto.

The attachment device 110, which has received no response from the house monitoring device 130 even though three polling messages are broadcast through steps S815 to S825, switches its monitoring mode from the home monitoring mode to the external monitoring mode. (S830). Then, the attachment device 110 is switched to the sleep mode (S835).

On the other hand, the portable tracking device 120 received three polling messages from the attachment device 110 through the steps S815 to S825, but did not receive a response response from the house monitoring device 130 once. The operation mode is switched from the monitoring release mode to the monitoring mode (S840).

Accordingly, the monitoring mode of the electronic supervision system is switched to the external monitoring mode. At this time, the portable tracking device 120 may notify the control center 180 that the monitoring mode of the electronic supervision system has been switched to the external monitoring mode.

Thereafter, the attachment device 110 wakes up (S845), and broadcasts a polling message (S850). The portable tracking device 120 broadcasts the reception response to the polling message (S855).

The attachment device 110 that receives the response from the portable tracking device 120 switches to the sleep mode (S860).

On the other hand, the house monitoring apparatus 130 that does not receive the polling message broadcast from the attachment device 110 three times in step S815 to step S825 switches its mode to the monitoring release mode (S865).

House monitoring device 130 knows the time required to perform the step S810 from step S810. Therefore, the house monitoring device 130 performs a mode switch to the unmonitored mode when the polling message broadcast from the attachment device 110 is not received during this time.

3. 이벤트 정보 전달3. Event Information Delivery

An event refers to an anomaly or unusual situation that may occur in a device. As an example of an event. Low battery, communication failure, device failure, device damage, etc.

(1) When an event occurs in the attachment device 110

As a result, the controller operating the control center server 180 is aware that the event occurred in the attachment device 110, it is possible to take follow-up measures.

Meanwhile, the control center server 180 receiving the event information transmits a reception response to the communication server 170 (S950). The communication server 170 receiving the reception response from the control center server 180 transmits the reception response to the 'portable tracking device 120 or the house monitoring device 130' (S960).

Then, the 'portable tracking device 120 or house monitoring device 130' transmits the received response to the attachment device 110 (S970).

(2) When an event occurs in the portable tracking device 120 or the house monitoring device 130

10 is a view provided to explain the process of delivering the event occurred in the 'portable tracking device 120 or house monitoring device 130' to the control center server 180.

As shown in FIG. 10, first, when an event occurs in the 'portable tracking device 120 or house monitoring device 130' (S1010), the 'portable tracking device 120 or house monitoring device 130 in which the event occurs is generated. ) 'Transmits the event information to the communication server 170 (S1020), the communication server 170 transmits the received event information to the control center server 180 (S1030).

As a result, the controller operating the control center server 180 recognizes that an event has occurred in the 'portable tracking device 120 or the house monitoring device 130', and can take a follow-up action.

On the other hand, the control center server 180 receiving the event information transmits the reception response to the communication server 170 (S1040). In addition, the communication server 170 receiving the reception response from the control center server 180 transmits the reception response to the 'portable tracking device 120 or the house monitoring device 130' (S1050).

4. 특정 대상 위치 파악4. Identify specific target locations

Hereinafter, the process of grasping the position of a specific object is demonstrated in detail. The procedure for determining the location of a specific target differs according to the operation mode of the electronic supervision system. Hereinafter, the process of identifying the location of a specific target is described in detail in the external monitoring mode and the home monitoring mode. Explain.

In order to determine a specific target location, communication between the portable tracking device 120 and the PDE 165 is required, and the communication between the two is performed through the relay of the 'mobile communication network 150'. In addition, in the other procedures described below, communication between the two is performed through such a relay.

In addition, in order to determine the specific target location, communication between the house monitoring device 130 and the PDE 165 is required, the communication between the two is made through the relay of the 'mobile communication network 150'. In addition, in the other procedures described below, communication between the two is performed through such a relay.

In addition, in order to determine the specific target location, communication between the PDE 165 and the control center server 180 is required, the communication between both is made through the relay of the 'M2M server 160 ↔ communication server 170'. In addition, in the other procedures described below, communication between the two is performed through such a relay.

(1) In case of external monitoring mode

1) first way

FIG. 11 is a view provided to explain the first method of identifying the position of a specific object in the case of the external monitoring mode. As shown in FIG. 11, when the control center server 180 requests the PDE 165 for location information on a specific object (S1105), the PDE 165 requests GPS information from the portable tracking device 120. (S1110).

Here, the 'GPS information' refers to the 'location information obtained by the GPS tracking satellites 120'.

The portable tracking device 120 receiving the GPS information from the PDE 165 acquires the GPS information using the built-in GPS receiving module (S1115), and transfers the obtained GPS information to the PDE 165 (S1120).

Then, the PDE 165 determines whether three or more pieces of GPS information received from the portable tracking device 120 are present (S1125).

If it is determined in step S1125 that the GPS information is three or more (S1125-Y), the PDE 165 calculates the location of the portable tracking device 120 using the GPS information (S1130).

On the other hand, if it is determined in step S1125 that the GPS information is less than three (S1125-N), the PDE 165 requests the base station information from the portable tracking device 120 (S1135).

Here, 'base station information' refers to 'location information obtained by the mobile tracking device 120 using the base stations built in the mobile communication network 150'.

And, if the GPS information is less than three, it may be due to the malfunction of the GPS receiving module or the portable tracking device 120 is located indoors or underground, so that three GPS information cannot be obtained.

The portable tracking device 120 that has received the base station information from the PDE 165 acquires the base station information (S1140), and transfers the obtained base station information to the PDE 165 (S1145).

Then, the PDE 165 calculates the location of the portable tracking device 120 using the base station information (S1150).

Thereafter, the PDE 165 transmits the location information calculated in step S1130 or step S1150 to the control center server 1180 (S1155). The control center server 1180 receiving the location information transmits a reception response to the PDE 165 (S1160).

2) the second way

FIG. 12 is a diagram provided to explain a second method of identifying the position of a specific object in the case of the external monitoring mode.

In the second method illustrated in FIG. 12, the PDE 165 requests base station information from the mobile communication network 150 (S1235), and the PDE 165 requests base station information from the portable tracking device 120 (S1135). This is different from the first method shown in FIG.

In addition, in the second method, since the mobile communication network 150 acquires the base station information and transmits it to the PDE 165 (S1240 and S1245), the portable tracking device 120 obtains the base station information and passes it to the PDE 165. There is a difference from the first method (S1140 and S1145).

A detailed description of the remaining steps shown in FIG. 12 is easily derived from the detailed description of the remaining steps shown in FIG. 11, and thus a detailed description thereof will be omitted.

(2) In house monitoring mode

1) first way

FIG. 13 is a diagram provided to explain a first method of identifying a position of a specific object in the case of house monitoring mode. As shown in FIG. 13, when the control center server 180 requests location information of a specific object from the PDE 165 (S1310), the PDE 165 requests location information from the house monitoring apparatus 130. (S1320).

The house monitoring apparatus 130, which has received the location information from the PDE 165, transmits its location information to the PDE 165 (S1330).

The PDE 165 transmits the location information received in step S1330 to the control center server 1180 (S1340). The control center server 1180 receiving the location information transmits a reception response to the PDE 165 (S1350).

2) the second way

FIG. 14 is a diagram provided to explain a second method of identifying a position of a specific object in the case of house monitoring mode. In this method, the control center server 180 is required to be able to determine what the monitoring mode of the electronic supervision system, the control center server 180 is a 'portable tracking device through step S550 of FIG. 5 and step S650 of FIG. The monitoring mode of the electronic supervision system may be determined by referring to the state information received from the '120 or the house monitoring device 130'. This is because the status information contains information about the monitoring mode.

As shown in FIG. 14, when the control center server 180 recognizes that the operation mode of the electronic supervision system is the house monitoring mode (S1410), the control center server 180 requests location information from the house monitoring apparatus 130 (S1420).

House monitoring device 130 receives the location information request from the control center server 180 transmits its location information to the control center server 180 (S1430). Then, the control center server 180 transmits the reception response to the house monitoring device 130 (S1440).

In addition, the control center server 180 considers the location information received through step S1430 as location information of a specific target (S1450).

3) third way

In the third method of determining the location of a specific target in the case of the house monitoring mode, the control center server 180 can check the operation mode of the electronic supervision system and know the position information of the house monitoring device 130 in advance. It is required to be.

The operation mode can be checked in the same way as the second method. In addition, the control center server 180 can know the location information of the house monitoring device 130 through the address contained in the personal information about the specific target registered through step S220 of FIG.

In this case, if it is determined that the operation mode of the electronic supervision system is the house monitoring mode, the control center server 180 considers the location of the specific target as the location of the house monitoring device 130.

5. 관제센터 서버의 요청에 의한 상태정보 전달5. Delivery of status information by request from control center server

Status information of the devices (attachment device 110, portable tracking device 120 and house monitoring device 130) is periodically transmitted to the control center server 180 through step S550 of Figure 5 and step S650 of FIG. do. However, as shown below, even if the period does not arrive, it may be delivered by the request of the control center server 180.

(1) Request / transmission of status information of the attachment device 110

The communication server 170 receiving the attachment device status information from the control center server 180 requests the attachment device status information from the 'portable tracking device 120 or the house monitoring device 130' (S1530).

In step S1530, the communication server 170, 1) when the mode of the electronic supervision system is the external monitoring mode, the portable tracking device 120 requests the attachment device status information, 2) the mode of the electronic supervision system is house monitoring mode If, the house monitoring device 130 requests the attachment state information.

The 'portable tracking device 120 or house monitoring device 130' that has received the attachment device status information waits until a polling message is received from the attachment device 110. This is because the polling message contains attachment status information.

When the attachment device 110 wakes up (S1540), and a polling message is received from the attachment device 110 (S1550), the 'portable tracking device 120 or house monitoring device 130' is received from the polling message. Extracting the attachment state information (S1560).

Then, the 'portable tracking device 120 or house monitoring device 130' transfers the extracted attachment device status information to the communication server 170 (S1570), the communication server 170 transmits the attachment device status information to the control center server Transfer to 180 (S1580).

(2) Request / transmission of status information of portable tracking device 120 or house monitoring device 130

FIG. 16 is a view provided to explain a process of transmitting status information of the portable tracking device 120 or the house monitoring device 130 to the control center server 180 at the request of the control center server 180.
