ATM monitoring trends and main points of self-service bank security prevention construction

ATM monitoring trends and main points of self-service bank security prevention construction

According to statistics, as of the end of 2010, the total number of ATMs in Chinese banks was approximately 212,000. Among them, the off-line automatic teller machine (ATM) accounts for more than 25% of the total. As an extension service of the bank's savings business counter, it serves the general public. The extensive use of automatic teller machines (ATMs) has made people increasingly dependent on automatic teller machines (ATMs). However, due to malfunctions of ATM products, network failures, use errors, human sabotage, and intentional fraud, various abnormal situations and business disputes have occurred in the application of ATMs, and some are illegal. The elements also took advantage of the automatic teller machine (ATM) to carry out criminal activities. Therefore, various banks have added monitoring equipment to ATMs in order to achieve the purpose of monitoring and evidence collection and dispute resolution. However, the large number of automatic teller machines (ATMs) and self-service banks, the geographical distribution, and the differences in installation environments have all raised higher and more requirements on how to ensure the security of users' cards, bank assets, and social security. It tends to customize the security requirements of Yuantuo Technology Company's ATM monitoring industry.

China's bank automatic teller machine (ATM) crime status

The huge profits and the prevention of loopholes have driven criminals to commit crimes with ATMs and card users rampantly. During the period from April to September 2009, public security agencies across the country filed 3672 cases, involving a total amount of 176 million yuan. These more than 3,000 cases can be roughly divided into three types according to the objectives of the crime.

1. With the goal of illegally stealing cardholders 'card numbers and passwords, burn fake cards to steal cardholders' bank card balances or huge overdraft credit cards.

The main means of committing crimes are: attaching a film to the ATM keyboard or installing a fake keyboard, installing a micro camera, installing a card reader at the ATM card slot or self-service bank access control, and automatically withdrawing cash. The machine (ATM) is equipped with a shell, posted false notices, fraudulently scamming the user's card number and password through the phone, installing card swallowing at the card insertion slot and the cash outlet, stealing bank cards, cash, etc.

The common feature of this type of criminal behavior is that criminals must install or destroy the ATM body, close to the periphery of the fuselage, and self-service bank access; the action is different from the normal withdrawal action of the user, infrared or vibration The detection technology cannot be effectively prevented, and can only be prevented and controlled through video surveillance or human inspection.

2. Taking the cardholder as the target of the crime, committing the crime through on-site robbery of the money collector, coercion and distracting the cardholder to change the bank card.

Such criminals usually follow the cash drawer and keep close to the cardholder who is making the withdrawal when committing the crime. There are fast actions such as shoving and fighting in front of the automatic teller machine (ATM) and there is a loud shout. It usually happens at a time when users are scarce and at a remote installation site. The circumstances of the case are fast to the end. It is difficult for bank guards and public security agencies to catch criminals on the spot.

3. Taking the automatic teller machine (ATM) as the target of committing crimes and stealing cash in the automatic teller machine (ATM) through prying, disassembling, blowing up, and whole machine handling.

This kind of criminal behavior is mainly based on the violent destruction of the automatic teller machine (ATM), and its large motion range will cause the automatic teller machine (ATM) to violently shake / shake. There have been many practical cases in China.

Deficiencies of traditional security systems

Due to the small number of early automatic teller machines (ATMs), fewer crimes, and a single approach, its focus is on protecting the bank ’s own assets. The main application is the "three heads and one device" structure security defense system, and there are many security defense Weak link.

It mainly relies on the bank security department to judge the police situation through monitoring video and vibration sensors, and then manually controls after the security department verifies the police situation. The video monitoring system cannot automatically alarm. When cutting and destroying the automatic teller machine (ATM), the vibration sensor usually cannot obtain vibration information to start the alarm system. In addition, when the surveillance camera fails and the cable is damaged, the effective video signal cannot be transmitted, and the system is in a paralyzed state. The security department can only know whether it is a device failure or a case through a site inspection. Suppose that when the case occurred, the surveillance image on the spot was not switched to the surveillance screen, and the alarm could not be discovered in time. Such loopholes make it more difficult to detect cases and cause huge losses to banks and users.

The construction of intelligent bank automatic teller machine (ATM) / self-service bank security system

Faced with a large number of unattended banks, scattered locations, and difficult bank inspection ATMs / self-service banks, the goal of building an intelligent bank ATM / self-service bank security system should be placed on Five application levels: network monitoring, linkage alarm, equipment integration, multi-user joint defense, and intelligent early warning analysis.

The means of security is transformed from the forensics afterwards to the identification of abnormal behavior and the tracking and control of the criminal process, so that the passive defense becomes active. Break through the information island with the construction of a global network, and realize the integration from traditional monitoring to intelligent identification, single monitoring to technical defense multiple systems. In terms of user management, from human inspection failure management to system automatic inspection report, from human-based management mode to system automatic alarm, historical image review after engagement to early warning and tracking of abnormal behavior, from traditional human management mode to Technology management, from the bank ’s own team management to the professional company ’s low-cost operation and maintenance services, from the indiscriminate inspection of a large number of images to the system automatically prompts the change of key information tracking.

The main preventive measures are:

§ Recognition of bayonet installation-to prevent illegal acts of installing card swallowing and card reading devices at the position of the swipe or card insertion port;

§ Recognition of the blockage of the cash outlet-prevent the use of tape or the like to block the cash outlet, and steal the cash while the cardholder is away;

§ Keyboard film identification-to prevent filming in the keyboard area or installing a keyboard to steal cardholder passwords;

§ Post false advertisements or identification of advertising boxes-by analyzing the scene around the ATM, to prevent the installation of micro cameras to steal cardholder passwords, fraudulent cardholder card numbers, passwords and transfer cases by means of false notification;

§ Identify ATM (Tampering with ATM)-to prevent cases such as prying, smashing, cutting and other violent destruction of ATM / self-service bank;

§ Wandering and staying identification——According to the fact that most of the criminals will have wandering and long-term staying characteristics before attacking the target, video analysis will be conducted on specific areas to judge suspects who have illegal tendencies and those staying in self-service banks;

§ Violent Robbery Recognition——Through the analysis and identification of quick actions to determine cases of assault, robbery, coercion, etc. in the scene;

§ Left-behind identification of objects-through the intelligent identification of newly added items in the scene to find suspicious objects or items forgotten by the cardholder, the cardholder can be promptly voiced through the front-end audio equipment;

§ Abnormal identification of video signals-through intelligent analysis of video signals, timely detection of human or non-human monitoring equipment failures such as video occlusion, video loss, camera shift, etc., and generating alarm signals to eliminate the failure in time;

§ One meter yellow line reminder-through a warm voice prompt for a safe distance of one meter, users withdrawing money can keep a certain safe distance while waiting for withdrawal users.

Advantages of Yuantuo Intelligent Video Surveillance

Due to the geographical dispersion, the maintenance of front-end systems for automated teller machines (ATMs) over a hundred orders of magnitude will become a heavy burden for bank security departments. Manpower inspection alone cannot guarantee the real-time detection of faults, and point-to-point daily inspections are also difficult to achieve . Nowadays, automated teller machines (ATMs) distributed in major cities, it is more difficult for commercial banks with more than a thousand levels to apply the original model to maintain automated service levels, and commission professional alarm operation service companies to provide 24/7 detection of equipment failures. Operations such as monitoring and alarm signal review and equipment maintenance and other services have become a trend. Service companies usually use fault detection technology to conduct patrol inspection to ensure the working conditions of front-end equipment to ensure real-time alarm of video occlusion, video loss, camera shift, hard disk failure, crash and other failures. For automated teller machine (ATM) monitoring and networking systems, it has the following benefits:

§ Change the post-event analysis and query into pre-warning;

§ Mainly use human activity monitor for alarm recording, and start recording when someone is close to the ATM to reduce disk fragmentation, and use motion detection recording as a supplement.

§ Adopting ATM intelligent anti-theft card system to prevent the crime of card insertion.

§ Replace the human eye with technology, analyze the picture in 24 hours, greatly reduce the operating cost;

§ Vibration monitor alarm combined with screen intelligent analysis alarm, and linked with the center to form a complete alarm and police rapid response mechanism; vibration monitoring equipment can record all the vibration waveforms that occur on the teller machine.

§ The host status monitor works 24 hours a day in real time to prevent the ATM monitoring host from crashing and affect the subsequent evidence collection.

ATM card number acquisition module and bank card number capture function can be used to superimpose the card number of the beneficiary on the video image in real time to provide effective legal evidence for later evidence collection.

Promote wireless alarm technology

The development of Yuantuo Technology Co., Ltd. has created the conditions for ATM networking. For a long time, ATMs have been highly mobile and the buildings themselves have limited network resources. However, current technology can realize ATM dynamic image monitoring in the coverage area. At the same time, bank-related management personnel, such as ATM managers, maintenance personnel, and supervisors, can use the mobile phone to make the sub-control system of the monitoring center directly monitor the authorized monitoring points.

The introduction of wireless alarm technology will promote the advancement of ATM security precautions. The battle against attack and defense of ATM security will surely exist for a long time. Only by relying on scientific and technological means can we continuously innovate and develop products that truly meet the needs of bank security prevention.
