Description

The present invention relates to an entry system and method of accessing a protected area, access to which is permitted only for authorized users.

From the existing level of technology, an entrance device to a protected area is known (patent for invention RU 2251747, publ.: 05/10/2005 Bull. No. 13). In the guarded zone, equipped with an electronic lock and a chip card reader connected to the control unit, there is a user terminal that is connected to an assessment center. The evaluation center is connected to the access event memory, to the control unit and to the control terminal, while the access event memory is also connected to the control unit. Such a scheme allows only authorized users with the appropriate chip card to enter the protected area. In addition, this scheme allows the user who detects damage to transmit messages about the detected status through the user terminal to the assessment center, which, comparing the time of changing the status of the protected area with the time of access events stored in the access event memory. The invention is aimed at monitoring the status of the protected area, identifying persons responsible for the changes that occurred in the protected area, and increasing the service life of the equipment. The disadvantage of this input device is the ability to access by card without monitoring the compliance of the pass to the employee or visitor. In addition, there is a low speed of information exchange with the server.

Known network control system and access control to premises based on biometric identification (patent for utility model RU 48656, publ.: 10/27/2005 Bull. No. 30). The network monitoring and access control system for premises based on biometric identification consists of at least one terminal comprising a reader, a controller, a light indication unit and an audible warning system, as well as a network adapter, an actuator connected to the controller, at least , one management object and server connected to the network adapter. The reader of the network system is optoelectronic, the fingerprint processing unit connected to the reader and the controller is additionally introduced into the system, the network adapter is integrated into the fingerprint processing unit and connected to the server using a high-speed interface. The controller is connected to an actuator of a relay type, made in the form of a digital microcontroller, allocated a digital channel. In the memory of the fingerprint processing unit using software, a buffer of events (reports) is generated with almost unlimited volume. The server of the network system may be a personal computer. The disadvantage of this system is the possibility of unauthorized entry into the building of intruders.

A common drawback of the known solutions is the lack of a single integrated solution for controlling access to the guarded facility with the possibility of self-registration of employees and visitors, as well as the exclusion (or minimal participation) of employees at the checkpoint.

The tasks to be addressed by the claimed invention are:

- Full automation of the pass office and checkpoint;

- the complete exclusion or minimization of the participation of employees of the entrance enterprise / organization, and, as a result, the elimination of human error and negligence when comparing data and passport photos or when entering data incorrectly during registration;

- Exclusion of criminal intentions of security / security personnel;

8. The module of light alerts.

The term "turnstile" in this description should be understood as a turnstile, vestibule gateway or any other device designed to restrict the passage of people in the event that it is necessary to check the right of entry and exit for each passing.

All elements of the system are interconnected by information transmission channels.

The non-territory access control system includes the following steps:

1. Self-registration of visitors / employees at the terminal, including:

- Scanning of identity documents;

- creating a reference photo of the face;

- comparison of the face and photo in the document;

- verification of the document for authenticity;

- recognition of the text in the document and its translation into an editable format;

- create an account.

2. The choice of services or appointments at the terminal.

3. Obtaining a pass at the terminal.

4. Passage through the turnstile, including:

- applying a pass to the turnstile reader,

- a look into the camera aimed at the turnstile,

- on the server, conducting face comparisons in front of the turnstile with a photo account;

- validation of the pass.

5. Countdown of time spent in the territory, starting from the moment of issuing the pass to the moment of leaving the territory through the turnstile, including:

- the beginning of the countdown from the moment of obtaining a pass and entering the territory through a turnstile;

- access to the room where the visitor was directed, by applying a pass to the reader at the front door, or by a mark in the system by an official;

- fixing the start time in the right room;

- fixing the time of leaving the premises;

- fixing the exit time through the checkpoint.

Self-registration is carried out through the terminal, which provides for:

- scanner of identity documents;

- IP cameras,

- devices for programming and issuing plastic card passes,

- a printer for printing one-time passes and supporting documents,

- touch monitor;

- microphone and speaker for communication or getting hints

from security guards or voice recognition and voice messaging software;

- server, or a separate system unit.

The hardware and software complex for face recognition includes software on the server and cameras for entry, exit, terminal. The hardware and software complex for face recognition is configured to record at least one person entering the territory, the presence of which requires preliminary registration with a pass, matching the person’s face passing through the turnstile with the data of the registered account and the validity of the pass, and transmitting information to the server about at least one person of the incoming person who did not match the account information and the validity of the pass. The turnstile blocking device is capable of reproducing an audio and light signal in the presence of at least one person who has not passed identification.

The turnstile is equipped with a system for blocking and supplying sound and light signals and the presence of:

- pass reader;

- blocking device;

- IP cameras;

- a controller for communication with the server;

- dynamics for the visitor’s voice alerts by turning on the module of prepared voice messages, or in case of questions from the visitor, with the speech bot (speech recognition and voice messaging software (server), or protection calls to the visitor;

- a microphone for exchanging voice messages with a voice bot (speech recognition and voice messaging software), or with a security service.

The ability to pass through the turnstile can be additionally controlled using a metal detector frame and an X-ray screener. Photos from these devices will be attached to the pass information.

The server can be a personal computer.

Information transfer channels can be wired channels, wireless channels. For example, Ethernet channels based on a twisted-pair cable cat.5 with a bandwidth of 100 Mbit and 1 Gbit, as well as fiber-optic communication lines (FOCL), can be assigned to wired channels. Wireless channels, for example, include WLAN networks based on Wi-Fi standards 802.11a, 802.11g, 802.11n.

Self-registration involves creating a user account in the system as follows:

- an identity document is attached to the scanner;

- The data of the scanned document is automatically converted into editable text and entered into the account;

- automatically built-in camera creates a reference photo;

- the created photo is compared with the photo in the passport. In the event of a recognition error, the security officer is sent a notification to the system’s memory for additional manual photo comparisons. Access inside opens only after confirmation by the security guard. At the same time, the operation of the terminal is not blocked, the person continues to issue a pass. A reserve of time is created for the response of the security service.

- if necessary, other personal data of the visitor may be entered.

The system provides assistance at any stage of registration, in any convenient format:

- step-by-step instructions posted on the foyer stands, with a detailed description of all actions;

- A system of tooltips that accompany all intermediate screens;

- a help call button, upon selection of which the display of the self-registration terminal is displayed on the operator’s display, and the operator is able to assist the visitor through the speakerphone and highlight the necessary buttons on his display. In case of communication with the speech bot, voice assistance comes from him, information about highlighting the necessary buttons is transmitted by the visual assistance software to visitors at the terminal.

Upon completion of registration and selection of services, or appointments, the terminal issues a pass. The paper pass received at the terminal is equipped with a barcode, information about the required service (letter code), the serial number in the queue, the current date and time of receipt, with preliminary on-line recording - the date and time of recording, and if necessary, a passage plan can be printed by the building. Visitors can also be issued with plastic passes. In this case, the output turnstiles are equipped with containers for receiving passes with the function of opening the turnstile for the last pass, and the terminal is equipped with a device for programming and issuing plastic passes.

With a pass issued, the visitor can go into the room through the turnstile.

Passing through the turnstile is as follows:

- the visitor looks into the camera lens and applies the previously obtained pass to the reader;

- The system recognizes a person and compares with account data. A pass or barcode reader contacts the server and requests a user account. The input camera sends data to the server to compare the person with the photo in the account. At the same time, the system provides for the recognition of people in profile, in glasses, hats, wearing a beard and mustache, as well as when moving, tilting and turning the head. For this, the camera takes several photos from the video sequence, both for choosing the best one and for photographing faces from different angles. This is necessary both to identify the maximum number of elements for comparison with the reference photo, and to exclude the possibility of cheating the system by attaching a photograph of a person whose pass is used for unauthorized access to the face of the attacker.

- the turnstile opens or is blocked. Upon successful verification, the turnstile opens, and a person can go to accessible areas. Otherwise, a beep sounds to deny access.

The system for counting the visitor’s stay in the territory consists of:

- a software module that compares the time intervals allocated for passing control points (set in the system) with timestamps received from skip readers or the employee interface;

- an electronic lock installed on the door to the office, or a special module in the employee’s interface for putting a time stamp on the beginning and end of the reception;

- guard notification module.

After choosing a service, the system warns the visitor about the time limit for access to the office and exit the building. Data on registration and the selected service is transmitted to the server, after entering the territory through the turnstile, the countdown begins.

To access the room you need to attach a pass to the reader at the office. The system compares the cabinet number with the list of available rooms for a given visitor and allows or denies access, the time of the event is recorded. If there are no electronic locks and card readers on the office doors in the building, it is necessary to check with the responsible person who will put the necessary mark in the system.

If the visitor does not fit into the set time, the security guard receives a notification about this. In this case, it is possible to organize a person’s search according to the list of events (entry / exit through any doors).

In addition, in the description of each event / reception, officials of the organization indicate the start and end times. This time is reflected in the list of visitor events, which can be useful if several people enter the office / department at a time for one pass.

The face recognition system also has the function of updating photos in the account during subsequent visits to the same visitor for more accurate verification.

When a visitor passes through the turnstile, the account of the recognized person is displayed on the monitor of the security point. Thus, the operator has the possibility of additional control of people passing through the checkpoint, and the system writes this information to the event memory.

Upon exit, the visitor also finds himself in the zone of the turnstiles - in the field of view of the camera. Applies a pass to the reader and looks into the camera. Upon successful verification, the turnstile opens.

For repeated access to the territory you need to go through the verification procedure and get a pass. To do this, you need an identity document to verify previously entered data, and look into the camera lens.

The system according to this invention completely eliminates the use of a pass by several people, since in order to open a turnstile or door lock, it is necessary to compare a living person in front of the camera with the account data caused by the pass application to the reader. For each person, an entry event is recorded, and until he exits through the turnstile, his pass cannot be used to re-enter. If a person left the room through the turnstile, then when using the card - a pass for re-exit, a signal is sent for security, and the passage through the turnstile is blocked.

The face recognition system using a photo from a video sequence significantly reduces the cost of the identification process compared to the three-dimensional formation of a person’s face, while eliminating the disadvantages of photo-identification systems that can be fooled by showing the camera a photograph instead of a living person’s face.

The verification system (one-to-one comparison in front of the camera and the photo of the account) and validation of the pass minimizes identification errors (one of many).

In addition to identification, the system compares visitors with a database of criminals, terrorists, persons suspected of crimes, and other blacklists. When these persons appear at the terminal or other cameras of the system with the face recognition function, an alert comes to the operator with the display of the current camera image and photo from the database. In this case, the visitor continues to work with the terminal, and security officers have the necessary time to organize events for the detention.

It also provides for the inclusion in the account of individuals with inappropriate behavior of restrictive labels that restrict access to the territory.

The system excludes free movement and uncontrolled presence of people in the organization.
