Due to the structure of the bank ATM automatic teller machine itself, the diversity of models and the unattended use environment, special requirements are put forward for the equipment and installation of the bank’s ATM machine security monitoring system:
Since bank ATM machines need to operate 24 hours a day, higher requirements are placed on the minimum illumination of the surveillance cameras used. Because the illuminance when there is a light box at night is about 15Lux; when there is no light box, the illuminance is less than 1Lux;
Since bank ATM machines are mostly installed in busy areas on the street, there are obviously many interference factors, so higher requirements are put forward on the detection distance and anti-interference measures of the installed human activity monitors;
Because the available space in bank ATMs is very small, and the internal structure and installation methods of different models are different, and the cameras and detectors installed need to be concealed, the selection of the installation location is greatly restricted. , Which puts forward higher requirements on the volume of the camera and the detector;
Bank ATM machines are unattended in addition to 24-hour operation. Therefore, the selected ATM machine security monitoring system equipment must be a trouble-free product that has truly passed quality inspection and quality certification, and it is best to have the necessary intelligent functions , In order to ensure the safe, normal, stable and reliable operation of the system, etc.;
In addition to operating 24 hours a day, bank ATM machines are also unattended. Therefore, the selected ATM machine security monitoring system is required to have the intelligent function of detecting and identifying abnormal behaviors of people and objects to ensure the normal operation of ATM machines and the lives of users And the safety of the property.
However, the convenience of ATMs in personal financial services saves banks a certain burden and obtains a lot of profits. At the same time, they have become a high-incidence location for crimes due to factors such as difficult management, multiple locations and scattered locations. Zhang Jun, head of technical defense of China Merchants Bank Shanghai Branch, said that for banks, self-service equipment is currently relatively concentrated and cannot and dare not ignore. Therefore, the bank mainly adopts security precautions for self-service equipment such as ATM machines. “Based on physical defense, guided by technical defense, and supplemented by civil defense”.
It is understood that ATM machines include two forms of self-service banking and off-line banking, among which off-line ATMs are mostly installed in commercial areas, residential areas, and hospitals with a large flow of people. Therefore, besides some security personnel around the ATM, it also has physical security measures. If thickened steel plate is used for ATM fuselage and wall-through ATM machine, steel bars are poured on the wall; an arch cover is added to the keyboard to prevent criminals from attaching a fake keyboard; a green bayonet is added to the bayonet to prevent artificial reading Card device and so on. The Shanghai Municipal Public Security Bureau also requires self-service equipment to install physical protective devices (such as screen guard doors) to provide customers with independent operating space and implement an automatic voice safety prompt system.
However, Zhang Jinguang, director of the ATM R&D Department of Yuantuo Technology, believes that although physical protection can play a certain role, with the increasing number of high-tech crimes now, physical defense is not particularly effective at certain moments. The technical defense is to solve this workload. As stated by Zhang Jun of China Merchants Bank, in view of the characteristics of its “self-service” application, China Merchants Bank requires that security guards should be able to “autonomously” realize most of the preventive functions.
The security system of ATM machines will develop towards intelligence and high-definition. Tianyinglong Zhang Fei said that the application of ATM anti-theft card system in ATM machines has just started, and the development of ATM anti-knife card technology will surely lead the development of the smart ATM security field.
How to prevent the increasingly rampant ATM theft cases? Comparison of the advantages and disadvantages of various technical methods.
The case of stealing the card number and password of the cardholder from the ATM, and cloning the bank card to steal funds has become a very headache for the police and the bank at present. From a technical point of view, one of the most basic elements required to clone a bank card is the bank card number. The only way to obtain the card number is through the card slot of the ATM machine. Therefore, criminals without exception install a stolen code device at the card slot. card number. From the perspective of precautions and warnings, guarding the card slot also guards the safety of the bank card.
Currently, there are two main solutions for anti-code theft:
1. Anti-theft code solution based on video recognition
This type of solution depends on many factors, such as whether the sharpness of the image meets the minimum requirements for video analysis, whether the image has been artificially disturbed (such as an umbrella, helmet, scarf, portrait mask, small pieces of reflective paper, etc.) or damage, whether The use of illegal stickers with polarizing capabilities, whether the image analysis and recognition algorithm is accurate, etc., many conditions must be met at the same time to implement intelligent analysis, so the intelligent image recognition system requires very ideal and harsh conditions, and in the real ATM machine withdrawal environment In this case, such conditions are almost non-existent, so the actual feasibility of the video-based intelligent surveillance system is very poor, and the actual use effect is also very unsatisfactory.
Anti-theft code scheme based on the principle of laser ranging
For any bank card theft crime that occurs on the teller machine, it has a common feature: the installation of additional equipment (theft device, fake keyboard, etc.). Any additional installation means that the space height of some important parts (card slot, keyboard, etc.) on the teller machine has changed. Real-time monitoring of the space height of these sensitive parts by high-precision measuring sensors can determine whether the normal card slot is added. It is equipped with code-pirates and other transformation behaviors, so that the alarm and early warning can be issued during the installation process, which can buy time for timely prevention and arrest of crimes. This system uses a phased laser ranging module to achieve high-precision laser multi-point ranging, which can form a laser protective net around the card reader. Since the equipment is hoisted at a certain distance in front of the self-service equipment, it is not only convenient to set up, good concealment, and no need to destroy Self-service equipment, flexible installation location, can be installed within a distance of 0.05 meters to 30 meters from the ATM machine card reader; in addition, the laser light path of the device not only has a large detection range, but also is not susceptible to environmental influences and electromagnetic interference, which effectively solves the traditional The problem of equipment false positives and false negatives.
In addition, Yuantuo Technology believes that the application of wireless communication personnel positioning technology will also play a role in ATM machines. With the implementation of the real-name system for mobile phones, when this detection technology is installed next to the ATM, the cardholder’s mobile phone number, name, serial number and other information can be detected. Once an illegal case occurs, wireless communication technology can be used to locate The current location of the suspect in order to quickly capture the suspect.
