Description

The utility model relates to the field of banking systems, namely, to the field of protection of ATMs, and can be used to protect the ATM system from hacking, as well as to alert about emergency situations with ATMs.

According to "Informzashita", 90% of attacks on ATMs were physical, the remaining 10% fell on skimming (installation of devices on ATMs that read the data of citizens' cards when they are the ones who suffer losses) and logical attacks. The latter accounted for less than 1% of ATM attacks. In 2016, ATMs were attacked 4 thousand times. According to the 2K auditing company, the damage from attacks on ATMs amounted to 2.5-7 billion rubles. In "Informzaschit" indicated that from one ATM criminals can steal up to 2 million rubles. In 2017, according to forecasts of "Informzashita", the number of attacks will grow by a quarter - up to 5 thousand. According to forecasts of "2K", damage from attacks on ATM will grow to 3-10 billion rubles.

Therefore, according to the author, it is necessary first of all to provide reliable protection against physical attacks on ATMs and payment terminals.

The most common means of physical protection of ATMs today are, first of all, alarms, video surveillance and various types of beacons. The latter are used if criminals are trying to physically steal an ATM, or some of its parts.

For example, a solution of the Stele company is known from the prior art (https://sosgps.ru/bankomaty). On it - using sensors and a special algorithm, the equipment analyzes the unauthorized fact of impact. If an object is attempted to be dismantled, the equipment switches to a different operating mode and sends a shock, fall or movement notification to the monitoring server via SMS or GPRS, the GPS receiver is also turned on and the location data is transmitted in real time. If the equipment cannot receive the signal from the satellites, the equipment sends location data to the LBS cell towers.

This solution was chosen as a prototype.

The negative side of this solution is that if the offender uses a signal blocker (for example, a blocker that simultaneously "jammers" the cellular communication ranges - 2G / 3G / 4G and GPS - https://pro-spec.ru/catalog/ blokiratory-besprovodnoj-sviazi / podavitel-skorpion-gsm-gps), this system will be ineffective (it will not be able to transmit any information, including its location).

The technical problem to be solved by the proposed utility model is to eliminate the shortcomings of the prototype - to increase the security of ATMs and payment terminals. The technical problem posed is solved due to the fact that the ATM security device contains a receiver for detecting a source of interference signals GPS, and / or GSM, and / or GPRS, and / or LTE, operating on the basis of monitoring the signal-to-noise ratio of the suppressor (JNR,) and a system for processing data received from a receiver (DOPD).

The device works as follows - the receiver constantly "monitors" the radio air in the specified ranges, the received data is transmitted to the DOPD. In this case, the receiver can be connected to the PDS in any possible way using wired or wireless technology. Different ranges for monitoring can be selected (depending on the possible type of jammer to be detected and depending on the operating ranges: GSM 900, DCS 1800, 3G / UMTS 2100, 3G / UMTS 900, CDMA 450, 4G / LTE800, 4G / LTE2500, Wi-Fi). In this case, when using, for example, in a security alarm radio beacon with additional frequencies, it is possible to expand the scanning ranges of the receiver. DOPD "memorizes" the ratio of the noise / signal level (for each range for each value of the carrier frequency) at a given location.

It is preferable that the device is inside the ATM (it can be fixed inside in any reliable way, for example, mounted on a bolt or self-tapping screw), while it is allowed, if necessary, to remove one or more receiver antennas.

Also, the system can be configured by the operator "manually" based on the conditions:

- what type of signal suppressor will be detected (what ranges will be monitored);

- what is the alarm threshold (for example, signal / noise exceeding by 10 dB);

- whether the excess will be sufficient in the entire range (for example, in the entire GSM range) or is it sufficient only in some part of the range;

- the ability to compare the excess signal / noise in one range with another (for example, a large signal level appeared abruptly in the GSM DownLink 925-960 MHz range, our system takes a close range of 900-920 MHz, if in this range there is also a sharp excess, then, most likely, some kind of broadband interference is working, which is not of interest. If not, then most likely it is the GSM signals that are jammed on purpose and the system is triggered. Similarly for other communication systems.

When a criminal tries to turn on a communication blocker for, for example, suppressing wireless security alarms and / or beacons (including beacons used to track the movement of an ATM), the receiver will record the excess of the signal / noise level and transmit this information to the PDS, which, based on the embedded algorithms (independent selection of these algorithms is allowed), will issue one or several commands (or will not issue if it considers it a "false alarm"):

1) Issuance of sound alarm;

2) Issuance of light signaling;

3) Triggering of the dye trap;

4) Transfer of information about this fact to the operator using possible communication channels (wireless - if they are not "blocked", wired, if, for example, they are not physically cut);

5) Transfer of command to video surveillance.

In this case, commands may not be issued simultaneously. For example, an algorithm can be set that the "coloring trap" for damaging money will not work immediately, but only, for example, after 15 minutes of detecting the fact of continuous blocking of a certain frequency range.

The technical result is to improve the security of banking machines.

The SOPD can be connected both to the existing security equipment of the ATM - for example, to video cameras, sound or light alarms, and be supplied with its own similar technical means (for example, if the ATM does not have a speaker for issuing a sound alarm, the device can be retrofitted with this technical means), then with these technical means DOPD (means of light or sound signaling, "coloring trap", video surveillance system, means of transmitting information to the operator - servers, etc.) can be connected in any possible way using wired and / or wireless technology.
