Description

Installed and Portable Wiretapping Surveillance System and Method thereof

The present invention relates to a wiretapping monitoring system and basically to a wiretapping monitoring system having a terminal that can be used both as an installation type and as a portable device.

An eavesdropping detection terminal is a device for checking whether there is an eavesdropping attempt by listening to a signal of a specific frequency band, and there are installed and portable types. While portable terminals are carried by administrators and use built-in antennas to detect radio waves suspected of eavesdropping, installation-type terminals are installed in a specific space, so multiple antennas can be used to set a wide monitoring range and prevent eavesdropping for a long time. can be monitored. In the case where eavesdropping does not occur regularly, the portable device has a disadvantage that it may not be able to detect eavesdropping signals, but is useful for urgent confirmation in a specific space. The installation type has the advantage of being able to check the entire wiretapping attempt while monitoring for a long time and monitoring a relatively wide area by extending the radio wave reception coverage by installing several antennas in advance.

In both the installed type and the portable type, it is possible to analyze the spectrum of a radio wave suspected of being eavesdropping to determine whether it is a eavesdropping signal, and to demodulate an audio or video signal to confirm the actual content of the detected radio wave.

Since the installed terminal is usually monitored for a long time, there is a problem that it is difficult for the user to observe it. Therefore, it is connected to the control server and is designed in a structure in which the controller monitors the wiretapping situation at all times. On the other hand, portable terminals do not have a function to connect to a control server, and are designed for direct monitoring in the field.

Figure 2 is a block diagram of the monitoring terminal of the present invention included in Figure 1;
3 is a view showing an example of a monitoring site divided into several monitoring areas, and
4 is a flowchart provided to explain the wiretapping monitoring method of the present invention.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

Referring to FIG. 1 , the wiretapping monitoring system 100 of the present invention includes monitoring terminals 110 and 130 for wiretapping monitoring, a user terminal 150 that can be connected to the terminals 110 and 130 , and a dedicated network 170 . It includes a control server 190 connected to the monitoring terminals 110 and 130 through the. The control server 190 may be connected to a plurality of monitoring terminals 110 and 130 . 1 is an example in which two monitoring terminals 110 and 130 are installed.

The dedicated network 170 is not only not a public network accessible by the public, such as a mobile phone network, a public phone network, or the Internet, but is also limited to a closed wired network that is not connected to the public network. The dedicated network 170 is usually installed in units of installation sites (public institutions, companies, etc.).

Since the two monitoring terminals 110 and 130 shown in FIG. 1 are the same device, hereinafter, the monitoring terminal 110 will be mainly described. The monitoring terminal 110 uses at least one antenna to track and analyze the wiretapping radio waves in the monitoring area (dotted line) of a certain range, and transmits the monitoring data, which is the analysis result, to the control server 190 through the dedicated network 170. or provided to the user terminal 150 . On the other hand, the monitoring terminal 110 of the present invention basically operates in an installation mode, but is characterized in that it can be used in a portable mode, and thus the monitoring area is not fixed and can be changed, and monitoring location information is included in the monitoring data. .

2, the monitoring terminal 110 includes a first communication unit 201, a second communication unit 203, a power supply unit 205, an input unit 207, a storage medium 209, a built-in antenna (ANT1), a signal processing unit 211 , a place recognition unit 213 , and a control unit 230 . A configuration related to the detection of an eavesdropping signal includes a built-in antenna ANT1 , an extended antenna ANT2 to be described below, a signal processing unit 211 , and a control unit 230 . However, the present invention is not characterized by the eavesdropping monitoring algorithm or the hardware configuration itself, and since there are many and various methods for monitoring and recognizing eavesdropping itself that have already occurred in the monitoring area in the prior art, the configuration of FIG. It should be regarded as an example of a means directly related to wiretapping surveillance. Therefore, the monitoring terminal 110 of the present invention can apply any number of methods known in the prior art, and may further include a hardware configuration required for a known algorithm in the prior art.

The first communication unit 201 is a network means connected to the control server 190 through the dedicated network 170 . Although various conventional serial communication may be used, an IP network with a wide bandwidth may be used to transmit audio or video files. On the other hand, in consideration of the characteristics and security of the dedicated network 170, each of the individual monitoring terminals 110, 130 is individually connected only to the control server 190, and it is preferable to have a configuration in which interconnection between the monitoring terminals 110 and 130 is impossible.

The second communication unit 203 is a wired or wireless network connected to the user terminal 150, and is a USB (Universal Serial Bus) method, a wireless LAN, a wired LAN, Bluetooth, Zigbee, etc. A known wired or wireless network can be used, and 1:1 communication is advantageous for security. On the other hand, the second communication unit 203 is set to operate only in the 'portable mode' in the operation mode described below, so that the connection of the second communication unit 203 is not allowed while the first communication unit 201 is connected. 2 The access to the dedicated network 170 through the communication unit 203 is fundamentally blocked.

The power supply unit 205 includes a power circuit for supplying internal operating power using AC commercial power, and includes a battery 205a and a charging circuit (not shown) for portable use.

The input unit 207 corresponds to a button, a keyboard, and the like for receiving various control commands or place information to be described below from the user.

The storage medium 209 stores a radio signal (including an audio signal and an image signal) acquired through the antenna, real-time monitoring data obtained by analyzing the radio signal, and the like. On the other hand, when the monitoring terminal 110 provides monitoring data to the user terminal 150 according to the portable mode, the same data is stored and managed in the storage medium 209 .

The built-in antenna ANT1 is a basic antenna built into the monitoring terminal 110 to listen to the eavesdropping signal, and is connected to the signal processing unit 211 . Meanwhile, according to an embodiment, the monitoring terminal 110 is provided with at least one antenna terminal 211a for connecting at least one extended antenna ANT2. The extended antenna ANT2 may detect a signal of the same frequency band as that of the built-in antenna ANT1 or may detect a signal (eg, LTE, 5G signal) of a frequency band different from that of the built-in antenna ANT1 .

The signal processing unit 211 collects radio waves using the built-in antenna ANT1 and the extended antenna ANT2, performs basic filtering, amplification, and the like, and provides it to the control unit 230 .

The place recognition unit 213 recognizes the place where the monitoring terminal 110 of the present invention is located and provides it to the control unit 230 . The place recognizing unit 213 may be any means capable of confirming the location of a specific indoor monitoring place in a manner that recognizes the identification means installed in the monitoring place.

For example, as shown in FIGS. 1 and 2 , the place recognition unit 213 may be implemented as an RFID receiver. Place recognition tags (Tags) 301 and 303 are disposed in each place, and identification numbers stored in individual tags 301 and 303 are set to indicate corresponding place information. When the RFID reader recognizes the tags 301 and 303 disposed in each place and reads the tag identification number, the mapped place information can be extracted to recognize the corresponding monitoring place. A first place where the dedicated network 170 is disposed among a plurality of areas monitored by the monitoring terminal 110 may be set as a default place. The place recognition unit 213 reads the tag identification number from the tags 301 and 303 and provides it to the control unit 230 . The controller 230 may use each tag identification number as the place information, or extract the place information using the tag identification number.

Alternatively, the input unit 207 may replace the place recognition unit 213 by receiving a place code from the user.

The control unit 230 controls the overall operation of the monitoring terminal 110 of the present invention, and generates a 'monitoring event' by determining whether the radio wave provided by the signal processing unit 211 is an eavesdropping signal using an eavesdropping signal detection algorithm. For this operation, the control unit 230 includes a wiretapping determination unit 231 and a mode setting unit 233 .

The eavesdropping determination unit 231 receives the radio signal from the signal processing unit 211 and determines whether the eavesdropping signal corresponds to a preset condition. When the radio wave is an audio signal or a video signal, the eavesdropping determination unit 231 may acquire an audio file or an image file by demodulating the corresponding signal. As described above, conventional methods for monitoring and recognizing wiretapping itself occurring in the monitoring area are very diverse, so the wiretapping determination unit 231 may use a conventionally known method as it is. The eavesdropping determination unit 231 generates a monitoring event when it is determined that the eavesdropping signal is eavesdropping.

The mode setting unit 233 controls the operation mode of the monitoring terminal 110 of the present invention, and when eavesdropping is confirmed during each mode, a monitoring event is generated and a corresponding process is performed. The mode setting unit 233 operates in the installation mode when the first communication unit 201 is connected to the dedicated network 170 , and automatically switches to the portable mode when the dedicated network 170 is not connected.

The mode setting unit 233 recognizes the location of the monitoring terminal 110 of the present invention based on the information provided by the place recognition unit 213 and the connection to the dedicated network 170, etc. Includes location information.

Hereinafter, with reference to FIGS. 3 and 4, the mode switching and operation in each mode of the monitoring terminal 110 of the present invention will be described.

installation type in mode movement

<Switching between installation mode and portable mode: S401>

When the first communication unit 201 is connected to the dedicated network 170 , the mode setting unit 233 switches to the installation mode. Referring to FIG. 3 , Room A is a place set as a 'basic place' where a dedicated network 170 is installed, and Room B is an extended space without a dedicated network 170 . Tags 301 and 303 are attached to each room. At least the identification number recorded in the second tag 303 indicates Room B. The first tag 301 is not necessarily installed in Room A, which is a basic location. For example, if the dedicated network 1870 is installed only in Room A, this is because Room A can be recognized by connecting to the dedicated network 170 .

When the monitoring terminal 110 of the present invention is connected to the dedicated network 170, the monitoring terminal 110 enters the installation mode. When entering the installation mode, the mode setting unit 233 turns off the second communication unit 203 and controls not to operate. Therefore, when the first communication unit 201 is connected to the dedicated network 170 (entering the installation mode), since it is impossible to access the monitoring terminal 110 using the user terminal 150, the monitoring terminal 110 is the user terminal ( 150) cannot provide monitoring data and data stored in the user terminal 150 cannot be provided toward the monitoring terminal 110.

If the first communication unit 201 is not connected to the dedicated network 170 , the mode setting unit 233 switches to the portable mode and allows the second communication unit 203 to connect with the user terminal 150 .

<Transmission of log data: S403, S405>

When returning to the installation mode, the mode setting unit 233 checks whether there is monitoring data generated during the portable mode and stored in the storage medium 209 . To this end, after returning to the installation mode, the monitoring terminal 110 checks whether there is monitoring data that has not been transmitted to the control server 190 in the storage medium 209 . Here, the monitoring data not transmitted to the control server 190 includes monitoring data provided to the user terminal 150 during the portable mode (S403).

If, in the storage medium 209, there is monitoring data that has not been transmitted to the control server 190, the monitoring terminal 110 transmits the monitoring data to the control server 190, thereby monitoring the monitoring situation during the portable mode by the control staff. to confirm (S405).

<Monitoring event during installation mode: S407, S409>

In the installed mode or portable mode, there is no difference between the detection of a wiretap signal using the built-in antenna ANT1 and the extended antenna ANT2 , the analysis of the signal processing unit 211 , and the operation of the wiretapping determination unit 231 . In the case of only portable mode, the monitoring range may be small because the installation of the extended antenna (AN2) is not easy. The monitoring data includes location information.

If there is a monitoring event in the installation mode (S407), the mode setting unit 233 provides monitoring data (and/or audio/video data) for the corresponding monitoring event to the control server 190 (S409). At this time, the monitoring data includes basic place information or the place information extracted with the identification number or identification number of the first tag provided by the place recognizing unit 213 and transmitted.

portable in mode movement

<Enter portable mode: S401>

According to step S401 , if the first communication unit 201 is not connected to the dedicated network 170 , the mode setting unit 233 switches to the portable mode, and the second communication unit 203 connects to the user terminal 150 . allow

<Location recognition and user terminal connection: S411, S413>

The mode setting unit 233 recognizes a place by using the tag identification number provided by the place recognition unit 213 after entering the portable mode. Since place information is mapped to each tag identification number, the mode setting unit 233 may check the current location. Referring to FIG. 3 , the monitoring terminal 110 of the present invention by recognizing the second tag 303 installed in Room B and entering the portable mode the moment the user separates the monitoring terminal 110 from the dedicated network 170 is It can be recognized that the current location is Room B mapped to the second tag identification number (S411).

The monitoring terminal 110 checks whether it is connected to the user terminal 150 through the second communication unit 203 . When connected to the user terminal 150 , monitoring data may be provided to the user terminal 150 . Although the connection confirmation of the second communication unit 203 is shown after the location recognition in step S411 in FIG. 4, the connection confirmation of the second communication unit 203 may be performed before the step S411 or in parallel with the step S411 ( S413).

<Monitoring event during portable mode: S415, S417, S419>

As described above, in the installed mode or portable mode, there is no difference between the detection of a wiretap signal using the built-in antenna ANT1 and the extended antenna ANT2, the analysis of the signal processing unit 211, and the operation of the wiretapping determination unit 231. In the case of the portable mode, it is not easy to install the extension antenna ANT2, so the monitoring range may be small, but the extension antenna ANT2 may be installed as many times as possible.

If there is a monitoring event in the portable mode (S415), the mode setting unit 233 stores monitoring data (and/or audio/video data) for the corresponding monitoring event in the storage medium 209 (S417).

When the user terminal 150 is connected, the monitoring terminal 110 provides monitoring data according to the monitoring event to the user terminal 150 so that the user can check the monitoring event. At this time, the monitoring data includes the tag identification number (eg, the second tag identification number of FIG. 4 ) or corresponding place information provided by the place recognition unit 213 and is transmitted. Even if the monitoring terminal 110 provides monitoring data to the user terminal 150, it is stored without erasing it from the storage medium 209 so that it can be transmitted to the control server 190 after being switched to the installation mode (S419).

In the above method, the monitoring operation of the monitoring terminal 110 of the present invention is performed.

Example (tag while moving through space)

The monitoring terminal 110 is switched to a portable mode as the connection with the dedicated network 170 is cut off, and can continue to monitor the wiretapping even before recognizing the tag identification number from the place recognition unit 213 .

During the place unconfirmed time, since it is not possible to confirm where the monitoring area is, the monitoring terminal 110 cannot input the place information into the generated monitoring data until the place recognizing unit 213 provides a new tag identification number. After that, when new place information is confirmed (or confirmed within a preset time), the monitoring data generated by the eavesdropping determination unit 231 and stored in the storage medium 209 during the place unconfirmed time indicates that it is between the default place and the new place. Place information can be inserted.

In the case of inputting place information through the input unit 207, information while moving may be separately input.

Example (tag for confirmation of departure from place)

Since the tag shown in FIG. 3 and described above is used to confirm arrival at an individual place, a tag for confirming departure from a place may be additionally used according to an embodiment.

In this case, the monitoring terminal 110 can accurately confirm arrival and departure in a specific space, and the monitoring terminal 110 can input corresponding place information only to monitoring data generated in a specific space.

In the previous embodiment of inputting information while moving, if a tag for confirmation of place departure is used, the monitoring terminal 110 can more accurately confirm that it is moving and input place information indicating that it is moving between space and space. In this case, this is applicable not only between the default location (Room A in FIG. 3) and another location (Room B in FIG. 3), but also between other locations (eg, between Room B and another location).

When the place information is input through the input unit 207, the place information can be input by dividing the place into arrival and departure.

another embodiment

According to another embodiment, when it is not possible to confirm where the monitoring area is, the monitoring terminal 110 waits for the monitoring operation until the place recognition unit 213 provides place information (eg, tag identification number). You may.

According to another embodiment, even when it is not possible to determine where the monitoring area is, the monitoring terminal 110 may generate monitoring data without place information and provide it to the control server 190 .

user terminal

The user terminal 150 may be any terminal provided with a display unit (not shown). The user terminal 150 may display the monitoring data provided by the monitoring terminal 110 as it is to the user or convert it into a form that the user can recognize and display. The user terminal 150 may further include a speaker (not shown) in order to check the decoded audio or video file.

control server

The control server 190 is a server that provides a wiretapping monitoring service, and as shown in FIG. 1 , a plurality of monitoring terminals 110 and 130 may be connected. On the other hand, since the dedicated network 170 is built in units of one monitoring site, a plurality of monitoring terminals 110 and 130 must also be installed in the same monitoring site. The control server 190 may operate a plurality of monitoring sites in a form in which a plurality of dedicated networks are connected.

The control server 190 outputs the monitoring data provided by the monitoring terminal 110 to the control personnel so that the control personnel can provide the control service in an integrated manner.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications may be made by those having the knowledge of, of course, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
