Research institutes and buildings that require security use their own security system or an external security system to restrict access. In particular, a research institute or a company controls the entry and exit of a person by using a card employing RFID (Radio Frequency Identification) for entry to and exiting from a building of the research institute or company. Alternatively, access is restricted by a method of controlling access using a human body characteristic, for example, a pupil or a fingerprint.

In particular, the RFID card is provided as an employee ID or pass, and only subscribers who are permitted using the provided RFID card can access the research institute or building.

Companies and research institutes inspect data leakage using storage devices such as USB and PC transport, and control transport according to separate rules. Companies and research institutes are taking security measures against data leakage by blocking the ports connected to the network or controlling programs and monitoring access and transmission to the network for data leakage using uncertified documents, PC transmission, storage devices and PCs. However, these methods have a problem that security is insufficient or may infringe personal privacy.

1 to 6 , the present invention is largely configured to include an information database 100 , a camera 200 , an access control unit 300 , and an alarm unit 400 .

First, the information database 100 includes pre-stored face information, name, unique number, age, position, floor information that can be accessed by each individual, information on whether access is possible to an area where access is restricted. , stores personal ID information, passwords, and ratings that can be connected to a preset network. In addition, the information database 100 stores RFID reader information, computer information within a predetermined area, and storage device information.

In the information database 100, pre-stored face information of people who can enter a predetermined area is a photo or camera submitted and stored by an individual who can access a predetermined area where security is set, such as a research institute, a company building, an IDC center, etc. It may be an image captured by (200). The pre-stored face information of people who can enter and exit a predetermined area is information necessary when entering a security-set area.

Name, unique number, age, and position are unique information linked with pre-stored face information of people who can enter and exit a predetermined area. For example, the unique number may be a company number, a resident registration number, or a randomly assigned number. The employee number and resident registration number are stored in the information database 100 in advance, and the randomly assigned random number is generated by the access control unit 300 and stored in the information database 100 . On the other hand, in the case of a temporary visitor, a photo is received in advance and a random number is given in response thereto.

The information database 100 stores information that can be accessed for each floor. Information that can be accessed by floor may be set in the information database 100 so that only floors set for each individual can be accessed. For example, in the case of a visitor visiting the research institute or building for business purposes, only the first floor and the floor where the meeting room or consultation room is set for visitation is set to be accessible. can be set to allow access. Alternatively, if you are a researcher at a research institute, you can set all floors to be accessible except for the two floors: the top floor where the president's office and executive-level personnel are located, and the floor where the design team is located. If you are a senior researcher, senior researcher, or executive, you can set all floors to be accessible.

The information database 100 includes information on whether access is possible to an area where access is restricted. Information on whether access to the restricted area is restricted due to security can be set in the information database 100 as the area requiring security among the research lab, design room, technical team, and production plant in the building where access is restricted due to security. For example, in the case of a design room, access restrictions may be temporarily set during a new product development period. The area to which access is restricted is set in the information database 100 so that only restricted persons can access. An area where access is restricted and a predetermined area where security is set have different meanings. For example, if a predetermined area in which security is set is a research institute, a building, etc., the area to which access is restricted may be one space within the research institute or the building. Access to a certain area where security is set is controlled by using the RFID chip and face information included in the pass, but access to an area where access is restricted is not included in the pass after entering the area with security set. Access can be controlled using an RFID chip. That is, the access of an individual who is not permitted to enter an area subject to access restrictions is controlled even when entering a predetermined area for which security is set.

In addition, when an unauthorized person enters an area where access is restricted, an alarm sound can be generated through location tracking.

The RFID reader information stored in the information database 100 records the location of the RFID reader installed in a laboratory or building, and a unique number of the RFID. The location of the RFID reader and the unique number of the RFID reader can be used to track the location of an individual, which will be described later.

In the computer information stored in the information database 100, the installation location of the computer, specification information of the computer, computer user information, computer repair and upgrade information, and the like are recorded.

The storage device information stored in the information database 100 stores owner information of the storage device, memory capacity, and the like. Meanwhile, all information of the information database 100 can be changed by an administrator.

The camera 200 captures images of people who can enter a research institute, a building, etc., stores the photographed face images as face information in the information database 100, and captures and recognizes the faces of individuals entering and exiting a predetermined area in which security is set. do. An image of each individual captured by the camera 200 may be used to control access by the access control unit 300 to be described later. Alternatively, an image captured by an external camera may be input and used as face information. In addition, the camera 200 may be installed on the entrance control unit 310 side of the access control unit 100 to be described later to photograph a person entering to obtain a face image.

The access control unit 300 controls an individual's entry into a security set predetermined area, controls the location, and controls access by floor. The access control unit 300 includes at least three RFID readers 1000 that can read the RFID chip included in the pass. The access control unit 300 determines whether to enter or not by using at least one of three RFID chips included in the pass. Since each RFID chip uses an RFID chip having a different frequency, access can be controlled using an RFID reader.

Referring to FIG. 2 , the pass 10 includes three RFID chips. First, the first RFID chip 12 is used as an access tag that allows only permitted people to enter and exit, and a chip of low frequency (LF) or high frequency (HF) is used. The second RFID chip 14 is used for location tracking and uses an ultra-high frequency (UHF) chip. The third RFID chip 16 uses another ultra-high frequency (UHF) chip capable of multi-tag and excellent recognition distance and performance. The third RFID chip 16 is used to recognize the floor where the occupant is located by storing the state information of the RFID chip.

The reason that the microwave RFID chip is adopted as the RFID chip is because the recognition distance is wide and the performance is excellent. In the above description, the RFID chip is embedded or attached to the storage device, the first RFID chip 12 is embedded or attached to the USB or chip-type memory card, and the storage device embedded in the computer is the same as the pass 10 . The first to third RFID chips 12 , 14 , 16 are attached or embedded therein.

If the information read by the RFID reader at the time of entry and exit is an individual who can access a predetermined area in the information database 100, the access control unit 300 calls the individual's face information from the information database 100 and calls the camera ( 200), it is compared with the face image to determine whether it is the same person. As a result of the determination of the access control unit 300 , if the face image captured by the camera 200 and the face information stored in the information database 100 match, access is permitted, and if they do not match, an alarm is issued through the alarm unit 400 . It outputs a sound to indicate that the individual is not a legitimate visitor.

The alarm unit 400 generates an alarm sound when an individual who is not authenticated by the access control unit 300 enters. The alarm unit 400 generates an alarm sound when a user who violates the rules is generated through the entrance control unit 310, the location control unit 320, the floor access control unit 330, the search unit 340, and the data approval unit 350, respectively. can be output. In addition, the alarm sound output by the alarm unit 400 generates a different output sound according to each rule and stores the details in the information database 100 .

The alarm unit 400 controls the entrance of an individual of the entrance control unit 310 to generate an alarm sound when an unauthorized individual enters a set area. The alarm unit 400 generates an alarm sound when an individual who violates the floor access rules is generated by the floor access control unit 330 . The alarm unit 400 is a case in which the individual possesses at least one of a document, a Universal Serial Bus (USB), and a computer that is not authorized by the search unit 340, and in the case of data transmission other than data transmission using a business network. for an alarm sound.

Referring to FIG. 3 , the access control unit 300 of the present invention includes an entrance control unit 310 , a location control unit 320 , a floor access control unit 330 , a search unit 340 , and a data approval unit 350 . do.

The access control unit 310 reads at least one of the three RFID chips 12 , 14 , and 16 included in the pass 10 using the entrance RFID reader 1000 to allow access or block access. When admission through the pass 10 is permitted, the access control unit 310 compares the face image of the object possessing the pass 10 through the camera 200 with the face information in the information database 100 . Control access. On the other hand, the access control unit 310 may refuse to bring in an unauthorized storage medium or paper. The entrance control unit 310 generates first alarm information and transmits it to the alarm unit 400 in case of unauthorized entry.

The position control unit 320 detects the position of the individual on which floor by detecting the pass the individual has by a plurality of position control RFID readers 1110, 1120, 1130, ..... 1180 installed on each floor. do. Detecting the location of an entrant and handoff through the location controller 320 will be described with reference to FIG. 6 to be described later.

The floor access control unit 330 detects movement by floor using the stair RFID reader 1200 and the elevator RFID reader 1210 installed at the entrance of the elevator of each floor and the stair entrance of each floor, and transmits the read information to the access control unit 300 ) to determine whether each individual is an individual who can enter each floor, and if a floor access rule is violated, the second alarm information is generated and transmitted to the alarm unit 400, and at the same time, the personal information of the person who violates the floor access rule is also generated. It is transmitted to the alarm unit 400 together. On the other hand, if there is an entrance on the first floor, the entrance control unit 310 performs the role of the floor access control unit 330 on the first floor, and also on the first floor, the movement detection RFID reader 1200 at the entrance of the elevator and the entrance of the stairs on the first floor. , 1210) are installed.

Referring to FIG. 4 , the search unit 340 is installed on the entrance/exit side, and includes an exit RFID reader 1300 and a document recognition sensor 342 . The search unit 340 is installed at a point where security is completed. For example, the point at which security is completed may mean the entrance/exit of a building or the front door of a research institute. The exit RFID reader 1300 and the document recognition sensor 342 detect whether or not a person who was in a security-set area leaves with a document, a storage device, and a computer. For example, when a person who was in a security-set area wants to escape to an unsecured area through an exit, the exit RFID reader 1300 uses an RFID chip attached to a registered storage device used in a predetermined security-set area. If recognized and recognized, the third alarm information is transmitted to the alarm unit 400 . Alternatively, when an RFID chip is attached or embedded in a previously registered storage device and recognized by the exit RFID reader 1300 , the third alarm information may be generated and transmitted to the alarm unit 400 .

Storage devices include hard disk drives, solid state drives (SSDs), USB (Universal Serial Bus), CF cards (Compact Flash CARDs), SD cards (Secure Digital Cards), MINI SD, It may be a storage device such as MICRO SD, MS (Memory Stick), or MS DUO. The RFID chip is embedded or attached to the storage device. In particular, USB or the above-described card-type storage device embeds or attaches only one RFID chip to control access only, and storage devices such as hard disk drives and SSDs (Solid State Drives) embedded in computers The three RFID chips used in the pass can be attached or embedded so that the location can be tracked.

The document recognition sensor 342 detects the release of the document, generates fourth alert information in the case of the release of the document, and transmits it to the alert unit 400 . That is, the document recognition sensor 342 recognizes paper used in a security-set area. The document here is a paper containing a special alloy as a security paper, and it is set to use only the paper set in the area where the security is set. It can be set in the aforementioned admission control unit 310 so that plain paper cannot be brought in.

The document recognition sensor 342 recognizes a special alloy included in the paper. When the document recognition sensor 342 recognizes a document, the fourth alarm information is transmitted to the alarm unit 400 .

The data approval unit 350 controls data transmission through online. The data approval unit 350 compares individual ID information and password in the information database 100 when logging in to the network by inputting individual ID information and password, and connects them when they match. The data approval unit 350 controls data transmission according to individual ID information and grades that can be connected to a preset network. The data approval unit 350 generates fifth alarm information and transmits the fifth alarm information to the alarm unit 400 when transmitting data that has not been previously approved even for an authorized user. Therefore, when data needs to be transmitted, prior approval from a high-level user is required, and mail or data is approved by a certain procedure. The data approval unit 350 may be transmitted after the approved mail or data has been approved and confirmed by a high-level user.

In addition, the data approval unit 350 filters the received data. We classify safe incoming mail that receives data flowing through a pre-approved and security-verified port and incoming mail or data through a pre-registered ID, and other incoming mail as insecure incoming mail. In case you want to receive it, you may need a separate approval from a high-level user.

The alarm unit 400 receives the first alarm information, the second alarm information, the third alarm information, the fourth alarm information, and the fifth alarm information, and outputs different alarm sounds when outputting them, so that each of the entrants through the alarm sound It is possible to recognize whether it is a violation of the rules when entering or exiting, whether it is a violation of the access rules for each floor, whether documents are leaked, storage device leaks, and data leaks through the network.

Referring to FIG. 5 , the location control unit 320 includes a plurality of RFID readers 1100 , 1110 , ..., 1170 and a location tracking server 322 . Although only eight RFID readers are indicated in the drawings for convenience of description, a larger number of RFID readers or a smaller number of RFID readers may be configured according to the size of a laboratory or building.

A plurality of RFID readers 1100, 1110, ..., 1170 is arranged to read the RFID chip included in an individual's pass to recognize the individual's unique information and to generate a common area of recognizing the pass.

The location tracking server 322 is wirelessly connected to the RFID readers 1100 , 1110 , ..., 1170 , and the information database 10 .

The location tracking server 322 detects the location of a person who has an RFID chip included in the pass. The location tracking server 322 recognizes the location of the main RFID reader 1100 that has detected the location of the person who has the RFID chip included in the pass as the initial location, and the signal sensitivity detected by the RFID reader 322 Form a circle corresponding to , and connect a circle-shaped line according to the sensitivity in the direction of the sensing area to the overlapping area between the RFID readers 1100 and 1150, so that the point where the circle and the line meet is the point of the individual who has the pass edit to location. For example, in the area overlapped by the two RFID readers 1100 and 1150, two contact points are generated, which can be recognized as two positions. However, one of the two locations is the wrong location and the other is the real location. However, this imaginary position is eliminated as it is easily recognized that one of the two positions is not a real position when either of the two positions is handed off or read by another RFID reader. That is, the location tracking server 322 may recognize the location of the entrant calculated from the locations of the plurality of RFID readers 1100 , 1120 , ..., 1180 stored in the information database 100 .

In a region overlapping between the RFID readers 322 , a handoff occurs toward a higher sensitivity.

The location tracking and handoff of an entrant will be described in more detail with reference to FIG. 6 to be described later.

Referring to FIG. 6 , person A is detected by the second RFID reader 1110 and is simultaneously detected by the third RFID reader 1120 and the sixth RFID reader 1150 , and person A enters the second RFDI reader 1110 ), so that the pass of the visitor A is read by the second RFID reader 1110 . Since entry A is being detected by three or more RFID readers 1110, 1120, 1150, the location of entry A can be easily detected by the trigonometric diagram method. When the positions are detected by two RFID readers, the two positions are detected by the trigonometric diagram method. In this case, the fake positions can be removed at the time of handoff or at the time of reading by other RFID readers. Alternatively, in the case of being read by one RFID reader, the contact point of the circle formed by the previous RFID reader and the circle formed according to the signal sensitivity of another RFID reader that has generated a read signal for the pass is determined as the position of the person.

For example, while entry A is being read by the second RFID reader 1110, it moves in the direction of the third RFID reader 1120 and moves to the A' position so that the sensitivity of the third RFID reader 1120 is increased by the second RFID reader 1110. ), it is handed off to the third RFID reader 1120 . That is, if the second RFID reader 1110 moves to A' while reading A, the sensitivity of the third RFID 1120 becomes higher than that of the second RFID reader 1110, so that reading for the entry and exit A is performed by hand. turns off

Alternatively, when the location of the person B is detected by one fourth RFID reader 1130, if only signal sensitivity is detected, the location of a wide linear area of an arc or circle is generated, but when moving to the location of B' A point B' at a point in time recognized within the signal sensitivity of the third RFID reader 1120 is determined as the location of the person entering B.

Since the location tracking and handoff using the RFID readers 1100, 1110, ..., 1170 may be affected by obstacles, they are installed on a ceiling or a wall near the ceiling in a building. That is, since there is no interference between RFID readers installed on adjacent floors, the RFID readers 1100 , 1110 , ..., 1170 can easily recognize which floor the entrant is on. In particular, in a building made of rebar and concrete or a building made of sandwich panels, floors and spaces can be clearly distinguished.

What has been described above is only an embodiment for implementing the face recognition system and method for measuring body temperature and detecting facial movement according to the present invention, and the present invention is not limited to the above embodiment, and is claimed in the claims below. As described above, without departing from the gist of the present invention, it will be said that the technical spirit of the present invention exists to the extent that various modifications can be made by anyone with ordinary knowledge in the field to which the invention pertains.
