Abstract

The utility model relates to access control devices. The device uses an additional executive path, which contains an additional control point, perceiving fingerprints of one of the fingers. The fingerprint is applied to the additional control point together (simultaneously or with a slight time difference) with the corresponding encoded element being a travel ticket, such as a travel card or social card, applied to the main control point. The signal from the ticket from the main control point along the main executive path is fed to the actuator, which is triggered “to the passage” only if the signal along the passenger’s fingerprint coincides with the fingerprint in the element that is the ticket. 1 ill.

Description

The utility model relates to access control devices that control the passage of people to the necessary objects, in particular to trains in various transport systems, including in the subway. The utility model can also find application in systems of mass access control of visitors in various areas of society.

In the framework of this utility model, the access control device is examined by the example of its use in the subway.

In all subways of the Russian Federation and in almost all subways of the world, turnstiles of one design or another are used to access trains, for example, those described in patent documents SU No. 266411, 1062739, RU 2158442 and EP 0173830.

In the turnstiles of the Moscow Metro, the actuator “on the way” is actuated using a relay, which is acted upon by a positive signal from an electronic or electromagnetic receiving unit, to the control point of which a correspondingly encoded element is approached (attached) - a ticket. The point to which the ticket is attached in the Moscow Metro is the reception window. In the future, the path from this window to the actuator will be referred to as the executive path for convenience. If an element that is not encoded correctly is applied to the window, or something else is applied, or nothing is applied at all, the actuator to the passage does not work, and the turnstile is closed.

In Moscow, since the 1990s, the main executive track of the subway checkpoint, in addition to the ticket, has also positively (that is, “to pass”) other elements that attest to the passenger’s right to a reduced fare. The most important of these elements is the Muscovite social card. According to 2009 data [Mathematical models for the formation of the input passenger flow of metro stations, RS Kudarov, the dissertation, defended in St. Petersburg. University December 12, 2009], up to 45% of Moscow metro passengers passed through social cards.

In recent years, unfortunately, a sad phenomenon has begun to be observed: many citizens who are not eligible for reduced fares use other people's social cards to pass through the Moscow metro turnstiles, and the metro as a modern transport structure suffers losses. This is due to the fact that the access control devices used in the subway do not have a high accuracy in identifying a person, namely the inability to make a reliable verification of the person’s personality itself.

In this regard, it becomes important to obtain reliable information about the compliance of the document, or pass, or identification card of the person who uses these documents.

The prior art system for personal identification (RU 2213998, G07C 9/00, publ. 10.10.2003). The principle of operation of such a device is based on the fact that the first subscriber on the first telephone sets confirms his identity to the second subscriber on the second telephone sets. To do this, a signal representing a fingerprint sample is generated, the generated signal is compared with the stored fingerprint signal, a match signal is generated if the stored and generated fingerprint signals match, and the match signal is used to address a memory storing a sign signal representing a characteristic sign of a predetermined persons or groups of persons transmit a sign signal to a point remote from the place where the fingerprint sample was taken, and generate at a remote point those are the output of the tag represented by the stored tag.

The disadvantage of this device is that the verification operation takes a lot of time due to the need for a remote communication session with the storage point of the registered original fingerprint of the subscriber. For single or non-mass calls, it is possible to use such a device with a time delay for identification. But for mass access systems for people, such as subway turnstiles, it is necessary to exclude time delays and carry out identification almost instantly. Only this will ensure proper traffic and a quick pass through the checkpoint of a large number of people at rush hour.

Also known is the access control device of the access turnstile with the function of monitoring the anthropological parameters of the passenger (JP 2001-243515, G07C 9/00, published 07.09.2001), containing the control point on the turnstile in the form of a receiving window to which the travel document is attached, including including a card with a chip, and an actuator that triggers a pass in the event of a positive signal from a control point, and in order to verify that the presented card really belongs to this passenger, the device has an element t, receiving the fingerprint of the passenger, the signal from this element is sent to the comparison node along with the fingerprint signal mounted on this card, and a positive signal from the comparison node starts the actuator to pass. This decision is made as a prototype.

In the application JP 2001-243515, verification is carried out in two stages: first, fingerprints are verified, which requires an additional storage unit - memory, from which data on the fingerprint is sent to the database of fingerprints previously received when issuing a card (unit storing personal data) by the entity selling or card issuer, and only at the second stage, the recorded memory of the result (after receiving confirmation from the database) is verified with the presented card. The two-moment verification significantly complicates it and also requires an increase in time for each pass of each passenger.

In the known device on the turnstile two reception windows are arranged, working on the principle of reading and scanning. The first is used to scan a fingerprint and transfer it to a common processor, the second is used to read a card with passenger identification data and transfer a block of read data to the same common processor. The fingerprint data is sent by the processor for comparison to the database, which contains the fingerprints of all users of all issued cards. If the fingerprint matches the database, the control signal is sent to the turnstile’s common processor, where the processors compare the reference fingerprint from the database with the fingerprint obtained from scanning from the card. And only after that the processor gives a signal to the turnstile relay to open the wings.

Despite the fact that the well-known solution uses a modern identification method, but its implementation in a particular device does not allow for the rapid passage of a large number of people, for example, during rush hour. It can be assumed how powerful the server should be, processing at the same time many operations to obtain fingerprints, search them in the database, conduct comparisons and provide answers simultaneously for a large number of people entering the metro at the same time. At the same time, the possibility of creating such a database and providing high-speed traffic is doubtful. Today it is a serious problem for hardware execution. We must not forget that this database is not cleared, but only replenished and provides eternal (very long) storage of data on prints and cards. In addition, the reliability of such a remote communication system of turnstiles with a database is also problematic: failure of the traffic system can lead to inoperability of all turnstiles and the inability to resolve the issue of passenger transportation.

This useful model is aimed at achieving a technical result, which consists in increasing the throughput of the access control device by conducting simultaneous verification of fingerprints from two separate receivers.

The technical result is achieved by the fact that in the checkpoint device with the function of monitoring the anthropological parameters of the passenger, containing a rack on which there is an element for blocking the passage, connected to the actuating unit for moving it to release the passage, a reception window is arranged on the rack to which an identifying user is applied a document containing a fingerprint of a user, and a window for scanning a user's fingerprint, as well as an electronic unit including the processing unit for data relating to the user identifying document, the processing unit for data obtained by scanning the user's fingerprint, the comparison unit for issuing a control signal, the power supply unit to the actuating unit for clearing the passage, in the electronic unit, the outputs of both data processing units are directly connected to the comparison unit for performing the operation of comparing the fingerprint contained in the document identifying the user with the scanned at the time of application to the receiving to the window of this document with a user's fingerprint and issuing a control signal to the power supply unit to the executive unit to clear the passage when establishing correspondence between the fingerprints, while the data processing unit related to the user identifying document is configured to transmit the control signal from its other output directly to the power supply unit to the executive unit to initiate its power supply function in the presence of a control signal from the output of the comparison unit.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a concrete example, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result by the given set of features.

In FIG. 1 shows a schematic solution of a checkpoint device with the function of monitoring the anthropological parameters of a passenger.

In the framework of this utility model, the design of the access control device with the function of monitoring the anthropological parameters of the passenger is considered. In the framework of the present description, the access control device provides high throughput by conducting simultaneous verification, for example, prints from two separate receivers. The aforementioned verification is carried out simultaneously, the executive path of the device has two simultaneously working inputs, the information on these two inputs ensures the actuator is triggered, which is easily implemented constructively provided that the social (or other permitting) card is finalized.

The essence of the claimed model is based on the user having an identifying document that carries personal information and a list of functions authorized for execution (financial, preferential, etc.) in a record or other form of hidden representation. In addition, such a document may carry anthropological information, such as a copy of a fingerprint, eye picture, etc. Such a document may be made in the form of a card.

For example, in RU 2212708, G06K 19/07, publ. 09/20/2003, such a card is described which is made with an integrated circuit adapted to interface with a card reader. The card contains a substrate, a storage device for storing data of the scanned fingerprint sample, a fingerprint sensor, an interface circuit with the card reader and a processing unit that compares the scan data with the sample data in the storage device to verify the eligibility of the user, and drives the circuit interfaces for exchanging card information with the host computer through the card reader when the bearer of the substrate is an authorized user. Such cards are easily supplemented by the usual standard set of elements that carry the user's personal data (like social or bank cards).

This utility model provides for the control of each passenger passing through the checkpoint, for example, on a social card, of its anthropological parameters that cannot be found in any other person. As a controlled parameter, fingerprints, palms, an iris pattern, and a number of others can be used. From the point of view of the problem under consideration, the most appropriate is the use of a fingerprint of one of the fingers, for example, the index finger of the right hand. The same fingerprint must be placed on this social card so that it can be read out by the window of the turnstile receiving device.

A feature of the utility model under consideration is that the circuit diagram of a checkpoint device such as a turnstile, for example, one that is installed in the subway, is preserved. But this circuit solution is complemented by the presence of a different executive path.

In the general case, the access control device (for example, a turnstile for the subway) (Fig. 1) contains a rack 1 on which an element of overlapping 2 passes is placed (a sash, sash or rods for a rotational type of turnstile). The movement of the floor element from the "passage closed" to the "open passage" position is carried out by the executive unit 3. The design of this executive unit 3 is not considered (does not apply to the essence of the claimed model), the main thing is that it performs the function of moving the floor element 2 to release the passage. In the initial position, in the absence of power or when power is supplied to the locking circuit of this actuating unit 3, the overlap element 2 closes the passage and does not have mobility. To change the position of the floor element 2, it is necessary to supply power to initiate the actuating unit 3 (if it was deactivated) or to apply power to the blocking circuit of this actuating unit. The power supply for the activation of the actuating unit 3 and the change of position of the overlap element 2 is carried out by the power supply unit 4 to the actuating unit 3.

Two reception windows 5 and 6 are organized at the counter. A document identifying the user (card) containing a fingerprint of the user is attached to the reception window 5. And the receiving window 6 is a window for scanning a user's fingerprint. Naturally, a data processing unit 7 related to the user identifying document is connected to the reception window 5, and a data processing unit 8 obtained by scanning the user's fingerprint is connected to the window 6. The reception windows on the surface of the rack themselves represent specially designed places that are receivers of identification tools, and the implementation algorithm itself is carried out in an electronic unit (see the callout in Fig. 1).

In the general case, the receiving window 5 and the associated processing unit 7 for data relating to a user identifying document are well-designed and hardware-designed and used tools such as card readers, which provide the ability to view and read data from tachograph cards, as well as other cards using similar principles of data recording, including universal electronic cards (UEC) (http://uec-reader.ru/wherebuy/). The use of a card reader (for example, grades ACS ACR38U-I1, ACS ACR38U-N1, ACS ACR38U-H1) is not related to specific software. This device is universal.

Em-Marine, HID Proximity, Temic and Mafare proximity card readers can be used - an essential element of an access control system of any complexity. Fundamentally, these devices can be divided into auxiliary, the signal from which is fed to the controller, or autonomous. The reader itself and the controller for it are integrated in the case of the latter (IronLogic Matrix-II - readers designed to work with cards and key fobs).

The methods of encoding and storing data on a card, as well as transferring data to a reader, vary depending on the technology used. But anyway, the data on the map is a string of binary data with some fixed configuration of a certain length. Card readers integrate with other devices in a single system for reading (and / or writing) information from a magnetic strip or barcode of a plastic card. So the cardholder is identified with its number. The magnetic card reader is designed for a significant number of uses and is used in various fields of activity: in automated teller machines, for non-cash payment of goods in retail, bonuses for purchases, access control and time tracking systems, and authorization in the computer’s operating system. Magnetic card reader is used in working with social cards.

As for the execution of the receiving window 6 and the associated unit 8 for processing data obtained by scanning the user's fingerprint, you can use the device described in RU 2212053, G06K 9/00, A61B 5/117, publ. 09/10/2003, which is used for fingerprint identification. This device contains means for forming an optical image of papillary lines on the matrix surface, a unit for setting the exposure of optical radiation irradiating the finger papillary lines, means for charging each capacitive element to a predetermined voltage, comparison means, a unit for generating a one-bit array of results of comparing the reference voltage with the voltage at each of capacitive elements after irradiation of papillary lines of the finger and controls. You can also use other technical solutions: a fingerprint reader FS-80 for registering fingerprints of users in BioSmart access control systems, ultrasonic fingerprint scanners using the technology of the American company Qualcomm with its Sense ID, scanners by BioLink, an optical fingerprint scanner R308 that works according to the method on reflection on the effect of disturbed total internal reflection (Frusted Total Internal Reflection), etc.

In any case, regardless of the hardware implementation, the unit 8 for processing data obtained by scanning a user's fingerprint implements the following algorithm:

A fingerprint image is generated. Image capture can be done using the built-in camera of the reader or by recording the potential difference of the electric field between the tubercles and the depressions of the papillary pattern. Combinations of methods are possible. The result is a digital black and white picture of fingerprint patterns.

The fingerprint image is converted into a mathematical model in which unique features, such as arcs, curls, loops and the distances between them, are stored as a digital code.

The electronic unit also includes a comparison unit 9 for issuing a control signal to the power supply unit to the actuating unit to clear the passage. This block is made with two inputs and one output. The outputs of both processing units 7 and 8 of the data are connected directly to the comparison unit 9 for performing the operation of comparing a fingerprint contained in a user identifying document with a fingerprint scanned at the time of application of this document to the receiving window of the document. The comparison process by the principle of verification is the algorithmic processing of prints by comparison by pattern or by specific points. The main task of the comparison unit is to compare the identifiable digital model with the template presented in wired form in the user document. Currently, fingerprint recognition is very fast. The technology has improved so much that identification time is measured in fractions of a second. Especially effective are electronic readers that identify fingerprints surprisingly quickly. Such companies as Identix, T-Netix, American Biometric Company, National Registry, Sagem, Morpho, Verditicom, Infenion successfully work in this direction. Of the Russian companies in the market of fingerprint recognition tools, the most famous are Elsis, Elvis, and Biometric Technologies.

The comparison unit is also made with the possibility of implementing the function of issuing a control signal to the power supply unit to the executive unit to clear the passage when establishing correspondence between fingerprints. Thus, the function of issuing a signal corresponding to establishing the coincidence of prints according to one of the known comparison methods in the claimed device is also equated to a control signal, which initiates the power on option in the power supply unit 4 to the actuating unit 3. But at the same time, the processing unit 7 for data relating to the user identifying document is configured to transmit a control signal from its other output directly to the power supply unit 4 to the executive unit to initiate its power supply function when there is a control signal from the output of the comparison unit. Thus, in order for the power supply unit 4 to fulfill its function, for example, according to the type of relay, it is necessary that the algorithmic element (logic element) of this unit receive two control signals. Only in this case the relay will open the power line for the actuating unit 3.

Thus, two executive paths 10 and 11 are formed in the electronic node: the first 10 is the path for processing data from the document and performing the function of perceiving a code denoting a social card. This function is performed in the same way as it is already known, and is currently implemented in turnstiles. The executive path 10 contains the main receiving window 5, the processing unit 7, the power supply unit 4 and the actuator 3, does not differ from the well-known circuit solution in modern metro turnstiles operating from the application of cards. In addition, in the event of a shutdown of the executive path 11 (for example, due to a scanner breakdown), the function allows passing passengers only on cards without fingerprints in the turnstile.

But it is possible that the print does not “sew” into the card body in the form of a digital version, but is photographed on the surface of the card. For this embodiment, an additional receiving window is provided in the receiving window 5, to which the passenger applies a social card so that the photograph with the fingerprint is on the field of this additional receiving window.

It is also possible that the receiving window 6 is executed on the field of the receiving window 5 (for ease of use and simultaneous application of the card and the finger.) In this case, two functions are superimposed on the executive path 10 at the same time: a) the perception of a code indicating a social card; b) the perception of a fingerprint. Function a) is performed in the same way as is already known, and is currently being implemented in turnstiles. And to fulfill the function b) the passenger together (simultaneously or with a slight time difference) applies a social card to window 5 and at the same time puts the index finger of the right hand on the field of window 6. Fingerprints from windows 5 and 6 processing units 7 and 8 are received in the comparison unit 9. If the comparison result is positive, the output signal from the comparison unit 9 is fed to the relay input and then to the actuator 3. If there is no positive signal from the comparison unit 9 (for example, when fingerprints do not match in windows 5 and 6 or if there is no fingerprint in one of them), the relay and the actuator 3 does not work, and this passenger is not allowed to pass. Thus, function b) is performed by an additional actuating path 11 containing a receiving window 6, processing unit 8, comparison unit 9, relay and actuator 3.

This utility model, in addition to the subway, can be applied in the practice of railways, in large enterprises, etc. The claimed device allows to provide high throughput by eliminating the loss of time comparing fingerprints received from two separate receivers, and by eliminating the need to use the central databases for storing fingerprints of passengers and card users.
