Description

The proposed utility model relates to techniques for protecting various closed guarded objects, as well as computing and information resources from the penetration of unwanted unauthorized persons, and can be used to identify a person when removing and arming automobile anti-theft systems, fire and burglar alarms, disarming and arming satellite monitoring and security systems, as well as identifiers for all types of existing classic control and management systems eniya access.

As an analogue of the proposed utility model, one can consider the device PW-303, manufactured by the Elix group, Russia [see Catalog “ACS. Anti-terrorism - 2005 ”, p.63]. The device is designed to build local access control and management systems (ACS) and is a stand-alone controller-reader compatible with Em-Marin or HID identifiers. PW-303 consists of a reader connected electrically to each other, installed near the controlled entrance, on a turnstile, gateway, etc., and a remote controller located inside the guarded room. Programming the device (up to 255 user codes) is carried out using a master card. Thus, a functional diagram of a known device comprises: a reader, a controller,

electrically connected to the reader, and an actuator (relay) integrated in the controller that controls the control object, that is, the lock. The described access control system has wide operational capabilities, for example, in case of danger, each user can enter the “pass under duress” code, which activates an alarm output, instead of an individual code, and if necessary (card loss, etc.), it is necessary to delete the code from the controller taken card. However, despite these advantages, the disadvantage of the known ACS is the presence of an identifier-card, which can be copied, lost or damaged mechanically. The disadvantages of the system should also include the combination of the actuator with the controller. The consequence of this is the low reliability of the system. In addition, a significant drawback of the device is that in case of loss of the card, it must be re-manufactured (that is, to incur material costs).

Currently, in the security industry, in the fight against crime and terrorism, biometric technologies are taking the lead. Identification using biometric technologies is one of the promising, rapidly developing areas, among which methods and tools using fingerprints occupy one of the leading places. The use of biometric systems that identify users by their unique physiological characteristics, such as fingerprints, can completely eliminate most of the drawbacks inherent in traditional access control and management systems, which include keys, cards that can be lost, forgotten, copied or transferred to another person.

The closest in its technical essence to the proposed utility model is a local control system for access to premises based on biometric identification, which

incorporates a device for biometric identification of individuals [see RF patent for utility model No. 47118, IPC G07C 11/00, G06K 9/00, publ. 2005.08.10], selected as a prototype. The utility model is designed to create autonomous access control and management systems based on biometric identification. The system includes the following electrically connected units: an optoelectronic reader (fingerprint scanner) and a microprocessor-based video image processing unit (fingerprints) with a memory that stores a database of fingerprints forming a fingerprint comparison device; controller (central) with a block of light indicators, a sound notification system and a data input device, which is a personal computer. Using the data input device, you can configure the system, add, delete fingerprints, as well as other operations with users. All of the above blocks form a device for biometric identification of a person. The system also contains an actuator made in the form of a digital microcontroller, and a control object (lock).

User identification in a known system is carried out using a device based on biometric identification of a person by determining individual biometric parameters obtained by scanning a fingerprint. Due to this, the system of persons with authorized access has been significantly expanded, the reliability of protection of protected objects has been increased, authorized users are guaranteed personalized access.

However, despite the undoubted advantages of the analyzed technical solution, selected as a prototype, it has a significant drawback, which lies in the limited functionality. This is due to the fact that the central controller of the device for biometric identification of a person,

included in the local access control system based on biometric identification, performs a certain, very limited range of functions, ensuring the operation of only a specific (analyzed) system. In addition, a significant drawback of the known device is the lack of the possibility of its integration with other systems.

The objective of the utility model is to expand the functionality of a personal identification device by converting it into a remote universal module that can easily be integrated with various systems (car anti-theft systems, satellite monitoring and security systems), fire and burglar alarms, access control and management systems, as well as integrates into traditional (non-biometric) systems.

To solve these problems, a universal biometric device for personal identification is proposed for access control and management systems, removal and arming of fire and burglar alarms, satellite monitoring systems and automobile anti-theft systems, which, like the device closest to it, selected as a prototype, contains a fingerprint scanner connected to a microprocessor-based fingerprint processing unit, including a memory for storing a fingerprint base, and a central th controller connected to the blocks of sound and light display and a data input device. A feature of the proposed utility model that distinguishes it from the well-known one adopted as a prototype of a biometric device for identifying a person is that the biometric device for identifying a person is made in the form of an autonomous module. The microprocessor-based fingerprint processing unit is connected to an additionally introduced interface module, which is connected via a digital interface to the central controller. Central controller

It is connected to the data input device through an additionally entered interface module using RS-232 or USB interfaces. In addition, the central controller is connected to the integration outputs block, equipped with interface and / or relay outputs.

To expand the functionality of the system into which the proposed biometric device for identifying the person will be integrated, the central controller can be connected to the unit for connecting external devices and sensors.

Currently, in connection with the intensification of the fight against crime and terrorism, personal identification using biometric technologies is one of the most promising and rapidly developing areas. This is due to the uniqueness of biometric information, which cannot be forgotten or lost, since its carrier is the person himself. That is why today the biometric component is actually becoming an indispensable element of modern security and anti-theft systems, control systems and access control to various closed guarded objects, computing and information resources. However, it should be noted that at this time in the market there are already many systems equipped with all kinds of devices (buttons, codes, passwords, electronic keys, electronic contactless cards), some of which are outdated and do not suit users. This circumstance enhances the relevance of the tasks posed by the authors when creating the proposed utility model, the implementation of which was made possible thanks to the following.

As mentioned above, the main task posed to the authors of the proposed utility model was the development of a biometric device for identifying a person as an independent autonomous module that can integrate with all kinds of systems (car anti-theft systems, satellite

monitoring and security systems, fire and security alarms, access control and management systems).

This problem is solved in the proposed utility model by isolating from the known, selected as a prototype, a local control system for access to premises based on biometric identification of those units that provide biometric identification of a person. This is a fingerprint scanner, a microprocessor-based fingerprint processing unit, a central controller, sound and light indication blocks, and a data input device. The listed blocks, supplemented by newly introduced modules and blocks (interface modules, integration outputs block), as well as new connections, are made in the proposed utility model as a separate module, the universality of which is the possibility of its connection and integration (integration) with various systems (car anti-theft systems, satellite monitoring and security systems, fire and burglar alarms, access control and management systems).

The second, no less important task is the replacement of outdated classic readers (contactless electronic card readers, electronic key readers, password keypads, etc.) installed in systems - automobile anti-theft, satellite monitoring, fire and other. This task is accomplished by connecting the central controller to the integration output block, equipped with interface or relay outputs, or both. Using the interface outputs, the claimed biometric device for personal identification can be connected to all currently existing security systems, including classical (non-biometric) ones. Moreover, the programming of the central controller operation algorithms can be carried out not only through the device

data input, as it was in the prototype, as well as through the service inputs to which external devices, sensors and buttons are connected. As a result of the inclusion of this additional feature in the formula, the functionality of the system into which the proposed biometric device for identifying the person will be integrated is substantially expanded.

Thus, the totality of the above features allows us to solve one of the urgent problems that have arisen at the present stage, namely: to replace the outdated traditional identification devices with modern biometric identification devices.

The proposed utility model is illustrated by drawings.

Figure 1 presents a functional diagram of a specific example of a universal biometric device for personal identification for access control and management systems, removal and arming of fire and burglar alarms, satellite monitoring systems and automobile anti-theft systems;

figure 2 is a structural diagram illustrating options for integrating the inventive device for identifying a person with various systems.

A universal biometric device for personal identification for access control and management systems, removal and arming of fire and security alarms, satellite monitoring systems and automobile anti-theft systems is made in the form of a remote autonomous module, which contains:

1 - fingerprint scanner;

2 - microprocessor-based fingerprint processing unit;

3 - memory for storing the base of fingerprints;

4 - interface module.

The blocks listed above form a comparison module 5.

Remote stand-alone module also contains a device 6 matching and generating signals, which includes:

7 - central controller;

8 - light indication unit;

9 - block sound indication;

10 - interface module;

11 - personal computer;

12 - unit for connecting external devices and sensors;

13 - block integration outputs;

14 - interface outputs;

15 - relay outputs;

16 is a digital interface.

In the presented in figure 2 structural diagram illustrating options for integrating the inventive biometric device for identifying a person with various systems, the following notation is introduced:

17 - automobile anti-theft systems, in which, instead of electronic keys and contactless cards, using the inventive biometric device, it is possible to carry out removal and arming by fingerprint;

18 - satellite monitoring systems, in which, instead of electronic keys, contactless cards and codes entered from the keyboard, using the inventive biometric device, it is possible to carry out the removal and arming by fingerprint;

19 - fire and security alarms, which, similarly to the systems mentioned above, can be removed and armed with the help of the inventive device;

20 - access control and management systems, for access to which the claimed biometric device can also be used by simulating a code from a contactless card or a code entered from a keyboard;

21 - access to a personal computer and other technical and financial means of information can also be carried out using the inventive biometric device.

The fingerprint scanner 1 is connected to a microprocessor-based fingerprint processing unit 2, which is connected to the central controller 7 by a digital interface 16 through the interface module 4. The central controller 7 is connected to the data input device 11 (personal computer) through the interface module 10 using any of the RS interfaces -232 / USB. The central controller 7 is also connected to the unit of integration outputs 13, equipped with interface 14 and relay 15 outputs.

In the proposed utility model, the fingerprint scanner 1 is designed to convert a bitmap image of the fingerprint into data that is transmitted to the microprocessor unit 2 for processing fingerprints. The microprocessor unit 2 for processing fingerprints is intended for preliminary filtering, processing, analysis and correction of the image obtained from the fingerprint scanner 1, and the subsequent conversion of fingerprint information into a unique biometric code corresponding to the presented fingerprint. In the process of operation of the device by this code, the user identification operation is performed, during which the reference code stored in the memory 3 of the comparison module 5 is compared with the biometric code of the presented fingerprint. The central controller 7 of the device 6 matching and generating signals is used to exchange information with the comparison module 5 through the interface module 4 via a digital interface 16. Central

controller 7 before starting work (after power is supplied) requests the comparison module 5 about the number of fingerprints entered and compares it with the number of fingerprints stored in the central controller 7. If the result is negative (the compared numbers are not equal), the identification device is blocked. In addition, when entering new fingerprints, the central controller 7 assigns each fingerprint an additional secret code stored both in the central controller 7 and in the comparison module 5, which provides the second stage of checking the possibility of an external scanner being replaced by an attacker. The programming algorithms of the central controller 7 is carried out through the data input device 11, made in the form of a personal computer connected to the central controller 7 through the interface module 10 using any of the RS-232 / USB interfaces. Programming can also be carried out through the service inputs “a”, “b”, “c”, which simulate codes issued from contactless cards.

Service inputs "a", "b", "c" are used to expand the functionality of the system into which the proposed biometric device for identifying the person will be integrated. The inputs control, for example, the input signals of the car doors, the brake pedal, which allows you to determine the fact of the robbery on the driver.

Digital inputs “g” (Wiegand) and “d” (Dallas code) are intended for connecting, for example, additional readers of contactless cards and electronic keys. Such a connection can be used, for example, for double identification: first, the user is identified by a contactless card or an electronic key, and then fingerprint identification is confirmed.

Interface outputs 14 provide the connection of the proposed universal biometric identification device to all

existing security systems. In addition, the interface outputs 14 allow for digital channels to simulate signals (see figure 2) from the classical types of identifiers (readers from contactless cards, electronic keys, keyboard, password, etc.).

Relay outputs 15 provide the output of analog signals for three types of events: “finger recognized”, “finger not recognized”, “alarm finger”. The outputs 15 can be used to connect directly to the control object, for example, a lock.

Blocks of light 8 and sound 9 indication are used for visual and sound display of the status of the identification device, its operation mode. Blocks of light 8 and sound 9 indication is controlled by the Central controller 7.

In the claimed utility model, both optical and capacitive sensors can be used as a fingerprint scanner 1 combined with a microprocessor unit 2 for processing fingerprints: for example, optical sensors of the Chinese company Futronic, capacitive sensors of the company UPEK, Inc. (USA), built on a specialized TouchChip module, as well as optical sensors manufactured by NITGEN (South Korea). The technical specifications of these sensors can be found at: www.upek.com and www.nitgen.com.

The central controller 7 is based on ATmega8L-8MI (MLF32) microcircuits manufactured by ATMEL (USA), as well as other industrial microcircuits, for example, ADM101EARM (mSOIC), 74HC125D (SO-14).

Other electronic components (display units 8 and 9, integration output block 13, interface modules 4 and 10, as well as the interfaces used in the device) with their main technical data are available on the following websites: www.nitgen.com, www.symmetron.ru, www .itis.spb.ru.

The integration of the inventive biometric device for personal identification in any of the systems 17-21, shown in figure 2, is as follows.

In any of these systems, instead of the existing identifier in the system, using the interface 14 and / or relay 15 outputs (see Fig. 1), the universal biometric device for identifying the person proposed in this application is connected using the interfaces used in the classical system. In this case, the central controller 7 enters a program - a signal simulator for the system into which the integration is performed. When programming fingerprints, an additionally simulated code is assigned to each finger, which is issued through interface outputs 14 when connected to a biometric identification system. After connecting and programming using the service inputs “a”, “b”, “c” or using the data input device 11, for example, a personal computer, it is necessary to carry out the procedure for entering fingerprints, which is carried out through the comparison module 5. The system is ready for operation.

The work of the proposed universal biometric device for identifying a person as part of the system into which it is integrated is carried out as follows.

The person with the right of access puts a finger on the window of the biometric fingerprint scanner 1. The fingerprint is read. The fingerprint information received by the scanner 1 is transmitted to the microprocessor fingerprint processing unit 2, in which it is converted into a unique code corresponding to the presented fingerprint, compared with the information stored in the memory unit 3 of the comparison module 5, and if the microprocessor fingerprint processing unit 2 matches through the interface module 4 through the digital interface 16 delivers to the device 6

matching and generating signals, a command signal, for example, a card number, which was mapped during recording, which then passes through the integration output block 13 to the interface outputs 14. At the same time, the green indicator lights up in the light display unit 9, and at the same time, an audio signal of indication 8 is issued. In case of identification failure, the red indicator lights up and a long beep sounds.

Thus, unlike the prototype, the proposed biometric device for identifying the person is easily integrated with various systems (car anti-theft, satellite monitoring and security systems, as well as fire and security alarms and access control and management systems). In addition, the proposed device can be integrated into all known traditional (non-biometric) systems by replacing classic readers (contactless electronic card readers, electronic key readers, password keypads, etc.) previously installed in these systems. It should be emphasized that when integrating the proposed biometric device for identifying a person, the functionality of the system into which the integration is carried out significantly expands.
