Description

Method and device for real-time monitoring of unauthorized entry using UHF band

[0001] The present invention relates to a method and device for real-time monitoring of unauthorized entry using the UHF band.

[0002] Typically, companies, government agencies, public institutions, and research institutes that require security must thoroughly manage the entry and exit of their buildings or specific spaces to prevent internal items or information from being leaked to the outside.

[0003] Recently, as communication technology has advanced, each company is creating a security environment based on various communication technologies.

[0004] The background technology of the invention has been prepared to facilitate a better understanding of the present invention. It should not be construed as an admission that the matters described in the background technology of the invention constitute prior art.

[0005] Previously, people visiting buildings or specific spaces occupied by companies, government agencies, public institutions, research institutes, etc. were required to manually record their personal information, purpose of visit, time of visit, etc. or input it into a computer system, and were then issued visitor passes or entry passes to allow entry to permitted spaces.

[0006] In this case, visitors can obtain entry by having their visitor's pass or entry ticket verified by the manager, or by touching the reader directly to obtain entry.

[0007] However, in the former case, there is a problem that a situation may arise where one enters without confirmation when the manager is absent or negligent, and in the latter case, there is a problem that a situation may arise where one enters after someone who entered first.

[0008] Meanwhile, the current method simply determines whether to grant entry by verifying the entry authority of the entrant, or after a problem occurs, it can only check the movement route or entry time of the unauthorized entry through the entry record or video, but there is a problem in that it cannot filter out whether the entrant is an unauthorized person at the time of entry or control the movement after entry.

[0009] The leak of industrial technology in corporate activities can not only weaken a company's competitiveness, but can also lead to the existence or demise of the company depending on the circumstances, and is an issue that has become a global issue as well as domestically. Therefore, the inventor of the present invention recognized the need to devote great effort to more thorough and careful management.

[0010] Accordingly, the inventor of the present invention has invented a method and device capable of monitoring entrants in real time by utilizing both a non-contact method based on UHF band RFID and a contact method based on a reader / recognition device, based on at least one recognition means.

[0011] Accordingly, the problem to be solved by the present invention is to provide a method and device for real-time monitoring of unauthorized entry using a UHF band, which detects the approach of an entrant through a non-contact method based on a UHF band, and confirms whether the entrant is scanned or recognized through a contact method based on a reader / recognition device, thereby enabling real-time detection of unauthorized entry as soon as the entrant enters a building or a specific space.

[0012] Furthermore, the problem to be solved by the present invention is to provide a method and device for real-time monitoring of unauthorized entry using a UHF band, which can enhance the security of internal items or information by controlling entry and exit so that an entrant deemed as an unauthorized entry cannot leave a building or a specific space even if he or she has entered.

[0013] The tasks of the invention are not limited to those mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0014] In order to solve the above-described problem, a real-time monitoring method for unauthorized entry using a UHF band according to one embodiment of the present invention is provided. The method may include the steps of: detecting a plurality of entrants who have approached within a preset radius from a first gate in a specific area based on at least one recognition means via the UHF band; determining whether to open or close an access restriction device of the first gate based on access request information received from a reader installed at the first gate in the specific area within a preset time period; determining whether access request information for each of the plurality of entrants has been received within the preset time period; and monitoring whether unauthorized entry has occurred in the specific area based on the determination result.

[0015] According to a feature of the present invention, the at least one recognition means includes at least one of an RFID tag, a beacon, a QR code, a barcode, and biometric information, and the biometric information may include information on at least one of a face, a fingerprint, an iris, and a vein.

[0016] According to a feature of the present invention, the step of detecting the plurality of entrants may include the step of recognizing the at least one recognition means through the UHF band and confirming unique identification information corresponding to each recognition means; the step of confirming each entrant mapped to the unique identification information corresponding to each recognition means based on a database; and the step of detecting the plurality of entrants based on each of the confirmed entrants.

[0017] According to a feature of the present invention, if there is a recognition means among the at least one recognition means that does not identify an entrant based on the database, the present invention may further include a step of transmitting a notification in a preset manner to notify that an unauthorized entry has occurred in the specific area.

[0018] According to a feature of the present invention, the entry request information is generated by having the relevant entrant scan the identification means he / she possesses at a reader installed at the first gate in the specific area or recognize it at a recognition device, and may include unique identification information about the relevant entrant.

[0019] According to a feature of the present invention, the step of determining whether to open or close the access restriction device of the first gate in the specific area may include the step of confirming the corresponding entrant corresponding to the unique identification information included in the access request information based on the database; the step of confirming whether the corresponding entrant is one of the plurality of entrants; and the step of transmitting a control command to release the access restriction device if the corresponding entrant is one of the plurality of entrants.

[0020] According to a feature of the present invention, if the entrant does not correspond to one of the plurality of entrants, the step of transmitting a notification in a preset manner to notify that an unauthorized entry has occurred in the specific area by regarding the entrant as an unauthorized entry into the specific area may be further included.

[0021] According to a feature of the present invention, if, as a result of the determination, an entrant is identified among the plurality of entrants who have not received entry request information within the preset time, the step of considering the identified entrant as an unauthorized entrant to the specific area and transmitting a notification in a preset manner to notify that an unauthorized entrant to the specific area has occurred may be further included.

[0022] According to a feature of the present invention, when it is detected that the unauthorized person has approached within a preset radius from the second gate in the specific area based on the recognition means for the unauthorized person through the UHF band, the method may further include a step of transmitting a control command to maintain the locked state of the access restriction device of the second gate in the specific area until a control command to release it is input.

[0023] According to a feature of the present invention, the control command to release the above can be generated when the identified entrant scans the identification means he / she possesses at a reader installed at the first gate within the specific area or has it recognized by a recognition device, or when the identified entrant scans the identification means he / she possesses at a reader installed at the second gate within the specific area or has it recognized by a recognition device.

[0024] In order to solve the above-described problem, a real-time monitoring device for unauthorized entry using a UHF band according to one embodiment of the present invention is provided. The device includes: a communication interface; a memory; and a processor operably connected to the communication interface and the memory, wherein the processor is configured to detect a plurality of entrants who have approached within a preset radius from a first gate in a specific area based on at least one recognition means via the UHF band, and, when entry request information is received from a reader installed at the first gate in the specific area within a preset time period, determine whether to open or close an access restriction device of the first gate based on the entry request information, determine whether entry request information for each of the plurality of entrants has been received within the preset time period, and monitor whether unauthorized entry occurs in the specific area based on the determination result.

[0025] According to a feature of the present invention, the at least one recognition means includes at least one of an RFID tag, a beacon, a QR code, a barcode, and biometric information, and the biometric information may include information on at least one of a face, a fingerprint, an iris, and a vein.

[0026] According to a feature of the present invention, the processor may be configured to, in the procedure of detecting the plurality of entrants, recognize at least one recognition means through the UHF band to confirm unique identification information corresponding to each recognition means; confirm each entrant mapped to unique identification information corresponding to each recognition means based on a database; and detect the plurality of entrants based on each of the confirmed entrants.

[0027] According to a feature of the present invention, the processor may be configured to receive the entry request information, which is generated by having the entry / exiter scan the identification means he / she possesses at a reader installed at the first gate in the specific area or recognize it at a recognition device, and which includes unique identification information about the entry / exiter, from the reader or recognition device.

[0028] According to a feature of the present invention, the processor may be configured to, if, as a result of the determination, an entrant is identified among the plurality of entrants whose entry request information has not been received within the preset time, consider the identified entrant as an unauthorized entrant to the specific area and transmit a notification in a preset manner to notify that an unauthorized entrant to the specific area has occurred.

[0029] In order to solve the aforementioned problem, an access terminal supporting both a contactless method and a contact method is provided according to one embodiment of the present invention. The access terminal is configured to be linked to a real-time monitoring system for unauthorized entry using a UHF band, and to detect the approach of the accessor through a contactless method that recognizes at least one recognition means based on the UHF band, and to confirm whether the accessor has been scanned or recognized through a contact method that recognizes at least one recognition means based on a reader or recognition device.

[0030] According to a feature of the present invention, the at least one recognition means includes at least one of an RFID tag, a beacon, a QR code, a barcode, and biometric information, and the biometric information may include information on at least one of a face, a fingerprint, an iris, and a vein.

[0031] According to a feature of the present invention, the first identification information used in the operation of detecting whether the person is approaching through a non-contact method of recognizing the at least one recognition means based on the UHF band can be configured to be provided to the server of the monitoring system.

[0032] According to a feature of the present invention, the second identification information used in the operation of confirming whether the entrant has been scanned or recognized through a contact method of recognizing the at least one recognition means based on the reader or recognition device may be configured so that the reader can transmit the second identification information to the server of the monitoring system.

[0033] According to a feature of the present invention, when the server of the monitoring system determines that the person entering or leaving is an unauthorized person, the monitoring system may be configured to receive a notification informing the user of the situation or a notification guiding the user on the procedure for releasing the unauthorized person.

[0034] The present invention detects the approach of an entrant through a non-contact method based on a UHF band, and verifies whether the entrant has been scanned / recognized through a contact method based on a reader / recognition device, thereby enabling the detection of unauthorized entry in real time as the entrant enters a building or a specific space.

[0035] In addition, the present invention has the effect of improving the security of internal items or information by controlling entry and exit so that even if an entrant deemed to be an unauthorized entrant enters, he or she cannot exit the building or a specific space.

[0036] The effects according to the present invention are not limited to those exemplified above, and more diverse effects are included within the present invention.

[0044] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. In connection with the description of the drawings, similar reference numerals may be used for similar components.

[0045] In this document, the expressions "has," "may have," "includes," or "may include" indicate the presence of a feature (e.g., a number, function, operation, or component such as a part), but do not exclude the presence of additional features.

[0046] In this document, the expressions "A or B," "at least one of A and / or B," or "one or more of A or / and B" can include all possible combinations of the listed items. For example, "A or B," "at least one of A and B," or "at least one of A or B" can all refer to cases where (1) at least one A is included, (2) at least one B is included, or (3) at least one A and at least one B are included.

[0047] The terms "first," "second," "first," or "second," as used herein, may describe various components, regardless of order and / or importance, and are only used to distinguish one component from another, without limiting the components. For example, a first user device and a second user device may represent different user devices, regardless of order or importance. For example, without departing from the scope of the rights set forth in this document, a first component may be referred to as a second component, and similarly, a second component may also be referred to as a first component.

[0048] When it is said that a component (e.g., a first component) is "(operatively or communicatively) coupled with / to" or "connected to" another component (e.g., a second component), it should be understood that the component is directly coupled to the other component, or can be connected via another component (e.g., a third component). Conversely, when it is said that a component (e.g., a first component) is "directly coupled to" or "directly connected to" another component (e.g., a second component), it should be understood that no other component (e.g., a third component) exists between the first component and the other component.

[0049] The expression "configured to" as used herein can be used interchangeably with, for example, "suitable for," "having the capacity to," "designed to," "adapted to," "made to," or "capable of." The term "configured to" does not necessarily mean something that is "specifically designed to" in hardware. Instead, in some contexts, the expression "a device configured to" can mean that the device, together with other devices or components, is "capable of." For example, the phrase "a processor configured (or set) to perform A, B, and C" may mean a dedicated processor (e.g., an embedded processor) for performing those operations, or a general-purpose processor (e.g., a CPU or application processor) that can perform those operations by executing one or more software programs stored in a memory device.

[0050] The terms used in this document are used only to describe specific embodiments and may not be intended to limit the scope of other embodiments. The singular expression may include the plural expression unless the context clearly indicates otherwise. Terms used herein, including technical or scientific terms, may have the same meaning as commonly understood by those of ordinary skill in the art described in this document. Terms defined in general dictionaries among the terms used in this document may be interpreted as having the same or similar meaning in the context of the relevant technology, and shall not be interpreted in an idealized or overly formal sense unless explicitly defined in this document. In some cases, even if a term is defined in this document, it cannot be interpreted to exclude the embodiments of this document.

[0051] The individual features of the various embodiments of the present invention can be partially or wholly combined or combined with each other, and as can be fully understood by those skilled in the art, various technical connections and operations are possible, and each embodiment can be implemented independently of each other or can be implemented together in a related relationship.

[0052] For clarity in the interpretation of this specification, the terms used in this specification are defined below.

[0053] For clarity in the interpretation of this specification, the terms used in this specification are defined below.

[0054] The device referred to as “service server” hereinafter may mean, but is not limited to, a single physically independent server according to the present invention, and may also be a single virtual machine, and is intended to encompass a single module or program or docker operating on a single virtual or physical machine.

[0055] Hereinafter, the present invention will be described in detail by describing a preferred embodiment of the present invention with reference to the attached drawings.

[0056] FIG. 1 is a schematic diagram illustrating a real-time monitoring system for unauthorized entry using a UHF band according to one embodiment of the present invention.

[0057] Referring to FIG. 1, a real-time monitoring system for unauthorized entry using a UHF band (hereinafter referred to as a "real-time monitoring system") (1000) according to one embodiment of the present invention may include a service server (100), an entry / exit terminal (200), a reader (300), and an administrator terminal (400). At this time, the entry / exit terminal (200) and the administrator terminal (400) are terminals of users who use a real-time monitoring service for unauthorized entry using a UHF band provided by the service server (100) (hereinafter referred to as a "real-time monitoring service"), and may be collectively referred to as user terminals.

[0058] First, the service server (100) may correspond to a web server and refers to a device for real-time monitoring of unauthorized entry using the UHF band in the real-time monitoring system (1000) of the present invention.

[0059] This service server (100) can be connected to an access terminal (200), a reader (300), and an administrator terminal (400) to collect or receive all information / data related to the real-time monitoring service. For this purpose, it can also be linked to a separate Application Programming Interface (API). An API refers to a collection of screen configurations, various functions, etc., that application developers need to easily develop programs that run on an operating system.

[0060] Meanwhile, the service server (100) receives first identification information transmitted based on at least one RFID tag via the first recognition means, i.e., the UHF band, to detect multiple entrants who have approached a specific area, and receives second identification information from the reader (300) to determine whether to open or close the access restriction device of the gate configured to allow entry into the specific area and / or the gate configured to allow exit from the specific area. At this time, the first identification information may also be transmitted to each entrant terminal (200).

[0061] At this time, the service server (100) can monitor whether or not an unauthorized person has entered the room by detecting multiple entrants and then operating a timer (not shown) to determine whether second identification information for each of the multiple entrants is received within a preset time.

[0062] Accordingly, the service server (100) can transmit and provide monitoring information including monitoring results to the administrator terminal (400). Here, the monitoring information may be set to be transmitted at preset intervals, but it may also be set to be transmitted whenever an entry occurs, or only when an unauthorized entry occurs. In other words, this can be set by the administrator, and the transmission conditions are not limited.

[0063] In addition, since there may be multiple administrator terminals (400), the service server (100) may transmit and provide the monitoring information only to at least one administrator terminal (400) preset among the multiple administrator terminals (400). For example, since each space within a specific area may have a different administrator, the service server (400) may identify at least one administrator corresponding to the space where an unauthorized entry occurred, and then transmit and provide the monitoring information to the administrator terminal (400) of each of the identified at least one administrator.

[0064] To this end, the service server (100) may receive, in advance, from the administrator terminal (400) user information, including information about users with access rights to a specific area, and store the information in a database. For example, access rights to a specific area may be granted by permission from the administrator terminal (400), and the user with access rights to the specific area may be provided with an RFID tag to carry, thereby transmitting the first identification information. In addition, the service server (100) may receive, in advance, from the administrator terminal (400) user information, including information about the administrator for the specific area and / or information about the administrator for each space within the specific area, and store the information in a database.

[0065] Here, at least one space may be formed within a specific area, and gates for entering or exiting the specific area, as well as for entering / exiting each space, may be installed. In this case, an access control device may also be installed at each gate and operated and / or driven independently. That is, each entrant may transmit second identification information to request the opening or closing of the access control device installed at each gate, not only when entering or exiting a specific area, but also when entering or exiting each space.

[0066] Meanwhile, the entry terminal (200) is a general term for a terminal possessed by each entry user who has been granted entry authority to a specific area among users registered on the service server (100) to use the real-time monitoring service. The terminal may be composed of multiple terminals, and the number and type thereof are not limited.

[0067] When each entrant approaches within a preset radius based on a specific point within a specific area, first identification information may be transmitted to the service server (100) based on the RFID tag carried by each entrant via the UHF band. Furthermore, the entrant terminal (200) may receive a notification or request from the service server (100). For example, if the service server (100) determines that the entrant is an unauthorized entrant, a notification informing of the situation may be received, or a notification guiding the user through procedures for unauthorized entry may be received.

[0068] Here, the entry / exit terminal (200) may be a device equipped (attached) with an RFID tag. However, each entry / exit terminal may only carry an RFID tag, and in this case, the RFID tag itself may be included instead of the entry / exit terminal (200) shown in FIG. 1.

[0069] Additionally, the reader (300) is installed at at least one gate within a specific area, scans a second recognition means, and transmits the second identification information obtained by the scan to the service server (100). At this time, the second recognition means may be a card, and may be a physical card or a mobile card.

[0070] At this time, the reader (300) may be linked / connected to an access control device installed at each gate. In this case, the reader (300) may receive a control command (lock command or unlock command) for opening and closing the access control device from the service server (100), thereby allowing the access control device to be controlled according to the control command.

[0071] Meanwhile, the administrator terminal (400) is a general term for a terminal possessed by each administrator who receives monitoring information for a specific area among users registered on the service server (100) to use the real-time monitoring service. The terminal may be composed of multiple terminals, and the number and type thereof are not limited.

[0072] To this end, a specific administrator (e.g., a general administrator) among the administrator terminals (400) can transmit and provide visitor information and / or administrator information to the service server (100).

[0073] When each manager receives monitoring information from the service server (100), he or she can take action on the space where unauthorized entry occurred based on the monitoring information.

[0074] Meanwhile, the access terminal (200) and the administrator terminal (400) may be a computer, UMPC (Ultra Mobile PC), workstation, netbook, PDA (Personal Digital Assistants), portable computer, web tablet, wireless phone, mobile phone, smart phone, pad, smart watch, wearable terminal, e-book, PMP (portable multimedia player), portable game console, navigation device, black box or digital camera, other mobile communication terminal, etc., which can install and execute multiple application programs (i.e., applications) desired by the access terminal and / or administrator, and are not limited to the aforementioned terminals.

[0075] Based on this real-time monitoring system (1000), the approach of an entrant can be detected through a non-contact method based on UHF band RFID, and by checking whether an entrant has been scanned through a contact method based on a reader, unauthorized entry can be detected in real time as soon as the entrant enters a building or a specific space.

[0076] The aforementioned FIG. 1 illustrates one embodiment of using an RFID tag as a recognition means for recognizing entrants. In other embodiments, the system may be configured to recognize entrants using at least one recognition means. These at least one recognition means may include at least one of an RFID tag, a beacon, a QR code, a barcode, and biometric information. Here, the biometric information may include information about at least one of a face, fingerprint, iris, and vein.

[0077] In this case, the real-time monitoring system (1000) may be equipped with a recognition device (not shown) for recognizing the biometric information of an entrant separately from the reader (300). For example, the recognition device may be configured to include at least one sensor and / or at least one photographing device. Here, at least one photographing device may be configured to include at least one of a 2D camera, a 3D camera, a ToF (Time of Flight) camera, a light field camera, a stereo camera, an event camera, an infrared camera, a lidar sensor, or an array camera.

[0078] Specifically, in another embodiment, the service server (100) may receive first identification information transmitted based on at least one recognition means via the UHF band to detect multiple entrants approaching a specific area, and may receive second identification information from the reader (300) and / or the recognition device to determine whether to open or close an access restriction device of a gate configured to allow entry into a specific area and / or a gate configured to allow exit from a specific area. In this case, the first identification information may also be transmitted to each entrant terminal (200).

[0079] In other words, according to another embodiment, by detecting whether an entrant is approaching through a non-contact method that recognizes at least one recognition means based on a UHF band based on a real-time monitoring system (1000) and confirming whether an entrant is scanned or recognized through a contact method that recognizes at least one recognition means based on a reader or recognition device, an unauthorized person can be detected in real time as the entrant enters a building or a specific space.

[0080] FIG. 2 is a block diagram showing the configuration of a service server for real-time monitoring of unauthorized entry using a UHF band according to one embodiment of the present invention.

[0081] Referring to FIG. 2, the service server (100) may include a communication interface (110), a memory (120), an I / O interface (130), and a processor (140), and each component may communicate with one another through one or more communication buses or signal lines. Meanwhile, although not shown in FIG. 2, an artificial intelligence-based pre-learning model may be stored as a module or stored in a separate learning model service server (not shown) linked to the service server (100).

[0082] The communication interface (110) can be connected to the visitor terminal (200) and the viewer terminal as well as other devices through a wired / wireless communication network to exchange data.

[0083] Meanwhile, the communication interface (110) that enables transmission and reception of such data includes a wired communication port (111) and a wireless circuit (112), wherein the wired communication port (111) may include one or more wired interfaces, for example, Ethernet, Universal Serial Bus (USB), FireWire, etc. In addition, the wireless circuit (112) may transmit and receive data with an external device via an RF signal or an optical signal. In addition, the wireless communication may use at least one of a plurality of communication standards, protocols, and technologies, for example, GSM, EDGE, CDMA, TDMA, Bluetooth, Wi-Fi, VoIP, Wi-MAX, or any other suitable communication protocol.

[0084] The memory (120) can store data for at least one process (algorithm) for providing a real-time monitoring service or a program that reproduces the process. Furthermore, the memory (120) can further store processes for performing other operations, but this is not limited thereto.

[0085] Meanwhile, the memory (120) can store various data used in the service server (100) as well as a pre-learning model built as needed.

[0086] In various embodiments, the memory (120) may include a volatile or non-volatile storage medium capable of storing various data, commands, and information. For example, the memory (120) may include at least one type of storage medium among a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., an SD or XD memory, etc.), RAM, SRAM, ROM, EEPROM, PROM, network storage, cloud, and blockchain database.

[0087] In various embodiments, the memory (120) may store configurations of at least one of an operating system (121), a communication module (122), a user interface module (123), and one or more applications (124).

[0088] An operating system (121) (e.g., embedded operating systems such as LINUX, UNIX, MAC OS, WINDOWS, VxWorks, etc.) may include various software components and drivers to control and manage general system operations (e.g., memory management, storage device control, power management, etc.) and may support communication between various hardware, firmware, and software components.

[0089] The communication module (122) can support communication with other devices through the communication interface (110). The communication module (122) can include various software components for processing data received by the wired communication port (111) or wireless circuit (112) of the communication interface (110).

[0090] The user interface module (123) can receive a viewer's request or input from a keyboard, touch screen, microphone, etc. through an I / O interface (130) and provide a user interface on the display.

[0091] An application (124) may include a program or module configured to be executed by one or more processors (140).

[0092] The I / O interface (130) can connect at least one of input / output devices (not shown) of the service server (100), such as a display, a keyboard, a touch screen, and a microphone, to the user interface module (123). The I / O interface (130) can receive viewer input (e.g., voice input, keyboard input, touch input, etc.) together with the user interface module (123) and process commands according to the received input.

[0093] The processor (140) is connected to a communication interface (110), a memory (120), and an I / O interface (130) to control the overall operation of the service server (100), and can perform various commands through applications or programs stored in the memory (120).

[0094] The processor (140) may correspond to a computing device such as a CPU (Central Processing Unit) or an AP (Application Processor). Furthermore, the processor (140) may be implemented in the form of an integrated chip (IC), such as a SoC (System on Chip) in which various computing devices are integrated. Alternatively, the processor (140) may include a module for calculating an artificial neural network model, such as an NPU (Neural Processing Unit).

[0095] Specifically, the processor (140) detects a plurality of entrants who have approached within a preset radius based on at least one RFID tag in a UHF band with respect to a first gate in a specific area, and when access request information is received from a reader installed at the first gate in the specific area within a preset time, determines whether to open or close the access restriction device of the first gate based on the access request information. Thereafter, the processor (140) determines whether access request information for each of the plurality of entrants has been received within a preset time, and monitors whether there is an unauthorized entry into the specific area based on the determination result.

[0096] Here, the entry request information can be generated by the entrant scanning the identification device in his / her possession at the reader (300) installed at the first gate of the specific area, and can include unique identification information about the entrant. That is, the unique identification information can be obtained by scanning the identification device at the reader (300).

[0097] Meanwhile, the processor (140) may determine that an unauthorized entry has occurred if entry request information is not received from each of the plurality of entrants detected within a preset time, or if entry request information is received from an entrant not included in the plurality of detected entrants (i.e., an entrant not detected based on an RFID tag). That is, the processor (140) determines that an unauthorized entry has not occurred only if the plurality of entrants detected through the two recognition means (the first recognition means and the second recognition means) are the same, and determines that an unauthorized entry has occurred if they are different. At this time, an entrant who is not recognized through either of the two recognition means is considered an unauthorized entry.

[0098] Additionally, if the processor (140) determines that an unauthorized entry has occurred, it transmits a notification to at least one pre-configured administrator terminal (400) in a pre-configured manner to notify that an unauthorized entry has occurred. Here, the notification may be the monitoring information described above, and the pre-configured manner may be based on at least one of audio, video, and text.

[0099] Meanwhile, when the processor (140) detects that an unauthorized person has approached within a preset radius based on the second gate in a specific area based on the RFID tag of the unauthorized person through the UHF band, it transmits a control command (lock command) to the reader (300) installed at the second gate or the access restriction device of the second gate to maintain the locked state of the access restriction device of the second gate in the specific area.

[0100] At this time, when a control command (release command) to release is received, the processor (140) releases the lock state of the access restriction device. In other words, the access restriction device that has been locked by a lock command due to the access of an unauthorized person maintains the locked state until a release command is input.

[0101] Here, the release order can be generated by an entrant identified as an unauthorized entrant scanning the identification means (second identification means) in his / her possession at a reader installed at the first gate or second gate within a specific area.

[0102] Meanwhile, in another embodiment, the processor (140) detects multiple entrants who have approached within a preset radius of a first gate in a specific area based on at least one recognition means via a UHF band, and, when access request information is received from a reader installed at the first gate in the specific area within a preset time, determines whether to open or close the access restriction device of the first gate based on the access request information. At this time, the entrant may use multiple recognition means, for example, an RFID tag-based recognition method and a facial recognition method may be used together. This enables more accurate recognition of the entrant.

[0103] Thereafter, the processor (140) determines whether all entry request information for each of the plurality of entrants has been received within a preset time, and monitors whether there is an occurrence of unauthorized entry to a specific area based on the determination result.

[0104] Here, the entry request information can be generated by the entrant scanning the identification means in his / her possession at the reader (300) installed at the first gate of the specific area or by having the identification means recognized by the recognition device, and can include unique identification information about the entrant. That is, the unique identification information can be obtained by scanning the identification means at the reader (300) or by having the identification means recognized by the recognition device.

[0105] This other embodiment is different from the first embodiment in that it recognizes an entrant using at least one recognition means including various forms of recognition means as well as an RF tag, and detects an unauthorized entrant based on the at least one recognition means. However, since the detailed operation is the same as other embodiments, it will be omitted.

[0106] The specific operation of the processor (140) described above will be specifically described below with reference to FIGS. 4 to 6.

[0107] FIG. 3 is a block diagram showing the configuration of a user terminal of an entrant or manager using a real-time monitoring service for unauthorized entry using a UHF band according to one embodiment of the present invention.

[0108] However, for the convenience of explanation, FIG. 3 will be explained based on the user terminal (200), but as previously explained, the user terminal can refer to both the user terminal (200) and the administrator terminal (400), and thus the explanation can also be applied to the administrator terminal (400).

[0109] Referring to FIG. 3, the access terminal (200) may include a memory interface (210), one or more processors (220), and a peripheral interface (230). Various components within the access terminal (200) may be connected by one or more communication buses or signal lines.

In addition, the access terminal (200) can store one or more software applications (256-1, 256-2) associated with a type of service (e.g., an application for a real-time monitoring service, an application for a broadcasting service, etc.) in the memory (250).

[0113] In various embodiments, the memory (250) may store a digital assistant client module (257) (hereinafter, DA client module), and accordingly, may store commands for performing client-side functions of the digital assistant and various user data (258) (e.g., user-customized vocabulary data, preference data, other data such as the user's electronic address book, etc.).

[0114] Meanwhile, the DA client module (257) can obtain voice input, text input, touch input, and / or gesture input from an administrator (user) through various user interfaces (e.g., I / O subsystem (240)) provided in the access terminal (200).

[0115] Additionally, the DA client module (257) can output data in audiovisual and tactile forms. For example, the DA client module (257) can output data consisting of a combination of at least two or more of voice, sound, notification, text message, menu, graphic, video, animation, and vibration. In addition, the DA client module (257) can communicate with a digital assistant server (not shown) using a communication subsystem (280).

[0116] In various embodiments, the DA client module (257) may collect additional information about the surroundings of the access terminal (200) from various sensors, subsystems, and peripheral devices to construct a context associated with the user input. For example, the DA client module (257) may provide context information along with the user input to a digital assistant server to infer the user's intent. Here, the context information that may accompany the user input may include sensor information, such as lighting, ambient noise, ambient temperature, images of the surrounding environment, videos, etc. As another example, the context information may include the physical state of the access terminal (200) (e.g., device orientation, device position, device temperature, power level, speed, acceleration, motion pattern, cellular signal strength, etc.). As yet another example, the context information may include information related to the software state of the access terminal (200) (e.g., processes running on the access terminal (200), installed programs, past and present network activity, background services, error logs, resource usage, etc.).

[0117] In various embodiments, the memory (250) may include added or deleted instructions. Furthermore, the access terminal (200) may also include additional configurations other than those illustrated in FIG. 3, or may exclude some configurations.

[0118] The processor (220) can control the overall operation of the entry / exit terminal (200), and can execute various commands to use the real-time monitoring service through the service provided by the service server (100) by running an application or program stored in the memory (250).

[0119] The processor (220) may correspond to a computing device such as a CPU (Central Processing Unit) or an AP (Application Processor).

[0121] The peripheral interface (230) can be connected to various sensors, subsystems, and peripheral devices to provide data so that the access terminal (200) can perform various functions. Here, the function performed by the access terminal (200) can be understood as being performed by the processor (220).

[0122] The peripheral interface (230) can receive data from a motion sensor (260), a light sensor (light sensor) (261), and a proximity sensor (262), through which the access terminal (200) can perform orientation, light, and proximity detection functions, etc. For another example, the peripheral interface (230) can receive data from other sensors (263) (positioning system - GPS receiver, temperature sensor, biometric sensor), through which the access terminal (200) can perform functions related to the other sensors (263).

[0123] In various embodiments, the access terminal (200) may include a camera subsystem (270) connected to a peripheral interface (230) and an optical sensor (271) connected thereto, through which the access terminal (200) may perform various photographing functions such as taking pictures and recording video clips.

[0127] For example, the touch screen controller (241) may detect a user's contact and movement or cessation of contact and movement using any one of a plurality of touch sensing technologies, such as capacitive, resistive, infrared, surface acoustic wave technology, or proximity sensor array. As another example, the I / O subsystem (240) may control other input / control devices (244) included in the access terminal (200) via other input controller(s) (242). As an example, the other input controller(s) (242) may control one or more buttons, rocker switches, thumb wheels, infrared ports, USB ports, and pointer devices, such as a stylus.

[0128] Fig. 4 is a flowchart schematically illustrating a method for real-time monitoring of unauthorized entry using a UHF band according to an embodiment of the present invention. Meanwhile, Fig. 5 is a diagram illustrating an example for explaining an operation of recognizing an entrant in a specific area to which a real-time monitoring system for unauthorized entry using a UHF band according to an embodiment of the present invention is applied, and Fig. 6 is a diagram illustrating an example for explaining a situation in which an unauthorized entry occurs when an entrant is recognized using an RFID tag and a reader according to an embodiment of the present invention.

[0129] In the following, in explaining Fig. 4, Figs. 5 and 6 will be used to explain each step in more detail.

[0130] First, referring to FIG. 4, the processor (140) detects multiple entrants (10) who have approached within a preset radius (hereinafter referred to as “first recognition radius”) (410) based on at least one RFID tag through the UHF band with respect to the first gate in a specific zone P (S110). At this time, the RFID tag may be carried by each of the multiple entrants (10), and each entrant may carry the RFID tag by equipping (attaching) it to a separate user terminal (device), or may carry the RFID tag itself.

[0131] At step S110, the processor (140) can automatically detect multiple entrants (10) by simply carrying the RFID tag and approaching (entering) within the first recognition radius of the specific area P without each entrant performing a separate action.

[0132] Specifically, the processor (140) recognizes at least one RFID tag via the UHF band, verifies unique identification information corresponding to each RFID tag, and verifies each entrant mapped to the unique identification information corresponding to each RFID tag through entrant information pre-stored based on a database. Accordingly, the processor (140) can detect multiple entrants (10) based on each of the verified entrants.

[0133] Meanwhile, although not shown in FIG. 4, if there is an entrant who is not confirmed based on the database among the plurality of entrants detected based on at least one RFID tag by step S110, that is, if there is an RFID tag among at least one RFID tag whose entrant is not confirmed based on the database, a notification to notify that an unauthorized entry has occurred in a specific area P can be transmitted to at least one administrator terminal (400) through a preset method.

[0134] This corresponds to the case of (a) in Fig. 6. If entrants A, B, and C, who have been pre-registered as entrants in the database based on the RFID tag, and entrant A', who has not been pre-registered as an entrant in the database and whose identity is unknown or who has not been granted entry permission, are confirmed, the processor (140) determines that an unauthorized entry has occurred due to entrant A'. At this time, the processor (140) may regard entrant A' as an unauthorized entry. That is, (a) in Fig. 6 is a situation in which an unauthorized entry has occurred before proceeding to step S120.

[0135] Next, the processor (140) checks the multiple entrants detected by step S110 through a database, and if entry request information is received from a reader installed at the first gate in a specific zone P within a preset time, it determines whether to open or close the entry restriction device of the first gate based on the entry request information (S120).

[0136] Specifically, the processor (140) verifies the entrant corresponding to the unique identification information included in the entry request information based on the database, and verifies whether the entrant is one of the multiple entrants detected by step S110. In other words, it verifies whether the entrant is included in the multiple entrants detected by step S110.

[0137] If the entrant is included in the multiple entrants detected by step S110, the entrant is granted entry to a specific zone P, and therefore, a release command is sent to the reader or access restriction device installed at the first gate to release the access restriction device, allowing the entrant to pass through the first gate.

[0138] In addition, if the entrant is not included in the multiple entrants detected by step S110, the entrant is not authorized to enter a specific zone P, and thus a lock command is sent to the reader or access restriction device installed at the first gate to keep the access restriction device locked, thereby preventing the entrant from passing through the first gate. In addition, the processor (140) may send a notification to at least one administrator terminal (400) through a preset method to notify that an unauthorized entry has occurred in the specific zone P.

[0139] This is a situation that can occur when an entrant who was not recognized based on the RFID tag at step S110 (an entrant who was not recognized) scans the second recognition means at the reader, or when an entrant who does not have an RFID tag but has the second recognition means scans the second recognition means at the reader, and corresponds to case (b) of Fig. 6.

[0140] As shown in (b) of FIG. 6, entrants A, B, and C, who were pre-registered as entrants in the database based on the RFID tag, were confirmed, and if entrants A, B, C, and D were confirmed through entry request information received from the reader within a preset time, the processor (140) determines that entrant D is an entrant who was not recognized through the RFID tag, and thus an unauthorized entry occurred due to entrant D. At this time, the processor (140) may regard entrant D as an unauthorized entry.

[0141] Next, the processor (140) determines whether all entry / exit request information for each of the plurality of entrants has been received within a preset time period (S130). That is, it determines whether all of the plurality of entrants detected in step S110 have scanned the second recognition means to the reader and transmitted the entry / exit request information, thereby confirming whether the plurality of entrants identified in step S110 and the plurality of entrants identified in step S120 match.

[0142] Next, the processor (140) monitors whether there is an unauthorized entry into the specific area based on the judgment result from step S130 (S140).

[0143] If, as a result of the judgment, it is confirmed that one of the multiple entrants has not received entry request information within a preset time, it is determined that an unauthorized entry has occurred in the specific area. This situation can occur when another entrant, detected based on the RFID tag in step S110, enters the area following the second identification method scanned by the reader in step S120, and corresponds to case (c) of Figure 6.

[0144] As shown in (c) of FIG. 6, entrants A, B, C, and D, who were pre-registered as entrants in the database based on the RFID tag, were confirmed, and if only entrants A, B, and C were confirmed through entry request information received from the reader within a preset time, the processor (140) determines that entrant D is an entrant who was not recognized by the reader, and thus an unauthorized entry occurred due to entrant D. At this time, the processor (140) may regard entrant D as an unauthorized entry.

[0145] In this case, since the unauthorized person has already entered through the first gate of the specific zone P, if it is detected that the unauthorized person has approached within a preset radius (second recognition radius) (420) based on the RFID tag of the unauthorized person from another gate of the specific zone P, i.e., the second gate, or that the unauthorized person is included among the multiple entrants (20) who have approached within the second recognition radius, a control command is transmitted to maintain the lock state of the access restriction device of the second gate. At this time, the lock state of the access restriction device of the second gate can be maintained until a separate unlocking command is input. As a result, the processor (140) can control the movement of the unauthorized person within the specific zone P.

[0146] Meanwhile, if it is confirmed that entry request information has been received from all entrants within the preset time, it is determined that there has been no unauthorized entry into the specific area.

[0147] This corresponds to the case (d) of Fig. 6. After entrants A, B, C, and D, who have been pre-registered as entrants in the database based on the RFID tag, are confirmed, a second recognition means is recognized through the reader, and entrants A, B, C, and D are confirmed as entrants for whom entry request information has been received. Since the entrant confirmed through the RFID tag is the same as the entrant confirmed through the reader, the processor (140) determines that no unauthorized entry has occurred.

[0148] As described above, one embodiment of the present invention detects multiple entrants based on at least one RFID tag via a UHF band in a service server (100), and monitors whether or not an unauthorized person has entered based on entry request information received from a reader (300). Hereinafter, based on FIG. 7, another embodiment will be described in which the reader (300) directly detects multiple entrants based on at least one RFID tag via a UHF band, transmits information to the service server (100), and further transmits information obtained by scanning an identification device carried by each entrant to the service server (100), thereby allowing the service server (100) to determine whether or not an unauthorized person has entered.

[0149] FIG. 7 is a schematic diagram illustrating a real-time monitoring system for unauthorized entry using a UHF band according to another embodiment of the present invention.

[0150] Referring to FIG. 7, when a reader (300) installed at a first gate in a specific area directly detects multiple entrants who have approached within a preset radius based on at least one RFID tag via a UHF band, access determination information (first identification information) including information on the detected multiple entrants is transmitted to a service server (100), and when each of the multiple entrants scans the recognition means they possess at the reader (300) within a preset time, access request information (second identification information) including information on at least one entrant detected through the scan is transmitted to the service server (100).

[0151] Accordingly, the service server (100) can compare the access judgment information and the access request information to determine whether to open or close the access restriction device of the first gate. In addition, a control command based on the decision can be transmitted to the reader (300) to enable opening or closing.

[0152] If the information on at least one entrant included in the access determination information and the access request information matches, the service server (100) determines that no unauthorized entry has occurred and transmits a control command to the reader (300) to unlock the access restriction device of the first gate. In addition, if the information on at least one entrant included in the access determination information and the access request information does not match, the service server (100) determines that no unauthorized entry has occurred and transmits a control command to the reader (300) to maintain the lock state of the access restriction device of the first gate.

[0153] In other words, in another embodiment, the service server (100) may be configured to determine an unauthorized entry by comparing information received from the reader (300) without detecting an entry or exit.

[0154] In this other embodiment, the operation of detecting multiple entrants in the reader (300) is the same as the operation of detecting multiple entrants in the service server (100) in FIGS. 2, 4 to 6, and the only difference is the subject of execution, so a detailed description thereof will be omitted.

[0155] Meanwhile, in explaining the present invention above, it was described that the service server (100) or the reader (300) detects multiple entrants who have approached within a preset radius from the first gate in a specific area based on at least one RFID tag through the UHF band, but this is only one embodiment, and the service server (100) or the reader (300) may be configured to use another band, such as the HF band.

[0156] As described above, according to the present invention, not only can unauthorized persons be detected in advance before entering a specific area, but even if an unauthorized person has entered the specific area, the security of internal items or information can be improved by controlling entry and exit so that the person cannot leave the building or specific space.

[0157] Although the embodiments of the present invention have been described in more detail with reference to the attached drawings, the present invention is not necessarily limited to these embodiments, and various modifications may be implemented without departing from the technical spirit of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, but to explain it, and the scope of the technical spirit of the present invention is not limited by these embodiments. Therefore, it should be understood that the embodiments described above are illustrative in all aspects and not restrictive. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
