From the perspective of the continuous occurrence of ATM machines across the country, the traditional monitoring model has been difficult to adapt to the current complex ATM deposit and withdrawal security environment. How to improve the security level of ATMs, strengthen the danger perception ability of ATMs, and change the passive defensive-style forensics as an active defensive-type early warning intervention have become an important topic for banks and security service providers. In order to facilitate relevant departments and organizations to understand the real problems, innovate security ideas, strengthen prevention capabilities, improve the image of the industry, and avoid the occurrence of ATM monitoring and construction in a form rather than an effect, we combine the security features of ATMs and self-service banks. Analyze the characteristics and development trends of various types of cases, and propose the security points and solutions for ATM machines in the new situation.
With the high incident rate for ATMs in recent years, all commercial banks have enhanced video surveillance measures against tellers and installed professional monitoring systems. However, due to the special nature of atm monitoring, many common monitoring areas have not been discovered. The problems have brought a lot of confusion to banks and engineering companies. In order to facilitate the relevant users to further improve the system, improve the monitoring mode, and better play the unique role of ATM monitoring, here are some common problems and some solutions. What areas are monitored by ATM monitoring? Need a few cameras? Generally, the main monitoring person faces the front, the banknote outlet, and the banknote counter area. The front camera of the person is mainly the frontal image of the withdrawal person or the destroyer. The camera at the banknote outlet mainly ingests the banknote withdrawal or abnormal situation of the banknote outlet. Monitor the moving images in the banknote dispensing process, in which the cash outlets and the banknote counterfeiting areas generally adopt the automatic Switch mode, so the real recording is two ways, but three cameras need to be installed. However, with the changes in the financial security situation, in recent days, public security departments in many places have put forward requirements for the installation of five cameras. This requirement is mainly directed at the monitoring of the surrounding environment of the tellers, that is, the need to supplement two cameras (each The environment cameras cover 90 degrees, and the two roads cover 180 degrees. This achieves panoramic coverage and prevents monitoring of dead ends, providing more comprehensive evidence for subsequent evidence collection. This way you need to install 5 cameras, the actual video is 4 channels. Why should the image in the password area of ​​the keyboard be obstructed? Due to the special structure of the teller machine, most cameras at the cash dispenser port will monitor the ATM machine's keyboard image. This will cause the image of the input password to be recorded. In order to prevent internal employees from committing crimes, part of the image of the ATM keyboard must be blocked. So as not to leave a security hole in the future. Why install an emergency help button on an ATM? What function should the button have? Due to the special nature of the withdrawal environment, when the payee feels danger or needs assistance in the withdrawal process, he can promptly and conveniently press the emergency button installed on the ATM operating panel in a timely manner, call the bank security personnel to handle or trigger the relevant sound and light alarm. The device, in order to prevent possible vicious events in a timely manner, the button can improve the bank's preventive ability, so as to better maintain the bank's reputation. The buttons generally have functions such as talkback, automatic broadcasting, and triggering alarm devices. What trigger video recording mode is used for ATM monitoring? With human activity monitor, vibration sensor and banknote sensor triggering video recording, video motion detection triggered recording is supplemented. The front camera is partially blocked How to deal with it? Due to the extensive installation of ATM monitoring, many criminal suspects also know that there is a monitoring system installed on the teller's machine. They also know that all cameras are blocked and the system will report a warning. In recent times, there have been cases where some cameras are blocked and the monitoring system has lost its function. For this new crime method, a combination of human activity monitor + image motion detection can be used. Why do I need to synthesize an image of a person's frontal image and a cash dispenser port into an image when recording? If independent video is recorded, many disputes will arise in the future when the court collects evidence. It will be more direct, reliable and effective to synthesize the frontal image of the person and the image of the cash outlet as an image without the need to make disputes.
First of all, do banks need an ATM monitoring system or a video forensics system? In fact, for bank users, early warning, stopping cases, and avoiding losses are the most basic requirements. However, the current surveillance system still stays in the post-video forensics phase, which directly leads to the entire incident being caught in the “case->loss->police-forensics->police-detection->bank-compensation->fatal-loss†circumstance. How to find the signs of crime and give warnings at the first time should be the most important part of the ATM security system. Only in this way can we stop crimes in a timely manner, avoid customer losses, and maintain the bank's image. Therefore, what the bank actually needs is not only a video forensics system but a full range of surveillance security systems.
Then ATM video surveillance system can solve the security problems faced by ATM machines? Is it the entire content of ATM security? Repeated cases across the country involving counters have repeatedly proven the basic fact that a pure video surveillance system cannot solve the security problems faced by ATMs. In addition, it is worth noting that the intelligent video surveillance system derived from video surveillance is subject to the complex environment of ATM security, and it is also not very satisfactory in small batch trials around the country.
Currently, video forensics systems are often misunderstood as the entire content of the ATM security system. In fact, the two are very different. It is undeniable that video surveillance systems do play an irreplaceable role in the evidence collection process after the incident, but the role played in the most important early warning stage is very limited. In the face of complex ATM machine use environment, it should be changed rapidly. The concept of passive video recording and recording established a three-dimensional prevention and control system based on various early-warning sensors and backed by video recording.
How to prevent the increasingly rampant ATM piracy cases again? Comparison of advantages and disadvantages of various technical means. Theft of cardholders’ card numbers and passwords on ATMs and the cloning of bankcards to steal funds have become a major headache for the police and banks. From a technical point of view, the most basic element for cloning a bank card is the bank card number. The only way to obtain the card number is the card slot of the ATM machine. Therefore, the criminals steal the card slot without exception. card number. From the perspective of preventing early warning, holding the card slot also keeps the security of the bank card.
At present, there are two main solutions to the problem of anti-piracy: 1. Anti-cryption schemes based on video recognition There are many factors that depend on such schemes, such as whether the resolution of the image meets the minimum requirements for video analysis and whether the image is affected. To human intervention (such as umbrellas, helmets, scarves, portrait masks, small pieces of reflective paper, etc.) or destruction, whether the use of polarized stickers with polarized light capabilities, image analysis and recognition algorithms are accurate, etc., many conditions must be met at the same time Intelligent analysis is implemented, so the smart image recognition system needs very ideal and harsh conditions. However, in the actual withdrawal environment of the ATM machine, such conditions hardly exist, so the practical feasibility of the video-based intelligent monitoring system is poor. The effect is also very unsatisfactory. 2. Based on the principle of laser ranging anti-theft code program Also mentioned ATM monitoring card number acquisition and card number superposition problems, it is troublesome, ATM monitoring video data why bank card number superimposed? What is a safe card number overlay? The superposition of bank card numbers can confirm a basic problem: the fact of who uses the card to withdraw money. At the same time the card number superimposed can be very convenient for quick retrieval after forensics. Therefore, the card number superposition plays a very important role in forensics, proof, and use.
The superposition of secure card numbers involves two aspects. 1. How to get the card number? Due to a number of security incidents, the domestic bank has now reached a general consensus on this issue: that is, it can only obtain the card number from the reader of the ATM machine and prohibit the card number from being retrieved from the network or the ATM host. 2. How to superimpose the card number? Whether the card number is completely or partially superimposed on the surveillance video is still controversial. However, from the perspective of security, it is necessary to prevent ATM surveillance and maintenance personnel, ATM maintenance personnel, and even bank employees from committing crimes, and to prevent criminal suspects from knowingly Stealing the video host to obtain the information of the withdrawal person, the complete superposition of the card number on the surveillance video is a very large security risk.
Now that the number of cases in which the monitoring system has been cut off from the power supply is increasing, how should we guard against such incidents? Judging from some cases that have already occurred, the criminal suspects frequently cut off the monitoring of the host, camera, and alarm power. Most of the current power supply uses the mains or the UPS to supply power in a unified manner. Once these devices are cut off, they lose their security. It is not difficult to solve such problems by installing anti-power destruction devices, such as “host status monitorsâ€. These devices can send out emergency SMS alarms, sound and light alarms, etc. in the event of a power failure.
Why is the ATM machine cash safe damaged, cut, and knocked? How can such an incident be solved? In some cases, the cash box of the ATM machine was cut. After the split, the installed shock sensor could not send out an alarm. This phenomenon is a typical missed report. The reason for this is because of the mechanism of the user's vibration during equipment selection. Not quite aware of the result. Vibration is actually an extremely complex phenomenon. The frequency, amplitude and direction of different vibrations are very different. Of course, a good solution is to install a three-dimensional vibration monitor in the cash box. Wherever possible, temperature sensors can be added.
How to quickly locate and determine the dangers and danger levels faced by ATM machines? Solution: The vibration monitor can be installed separately for the cash box and the panel, so that it can determine what kind of vibration is occurring and based on what purpose of the destruction. For example, the vibration monitor alarm in the cash box can determine that someone is destroying the cash box is a high-risk crime, and the panel vibration monitor alarm can be judged as an ordinary violent destruction behavior.
About the ATM monitoring application The video motion detection function is applicable to ATM security? How to avoid the generation of junk video? The use conditions of video motion detection are generally in a closed environment, such as a bank business office, a vault, a warehouse, and the like, to trigger recording or alarm when someone or an object moves. Most ATMs are installed in transparent self-service banks or are independently installed on the streets. Although self-service banks are closed on the surface, the glass-transparent camera images cover non-self-banking neighborhoods, resulting in non-payment of deposits and withdrawals. Busy behavior will trigger ATM video surveillance host video, these invalid videos often occupy a lot of hard disk space into junk files. Therefore, the video motion detection function does not apply to the ATM security environment.
An effective way to avoid junk video is to install a human activity monitor to trigger recordings when someone is near 0-3 meters away from the ATM, thus maximizing the use of hard disk space and prolonging the life of the ATM monitoring console.
In fact, it talked about how to prevent the ATM monitoring system from being destroyed. This is also the current situation in which most ATM monitoring consoles are located in or near ATMs. The phenomenon of criminal suspects destroying or even stealing ATM mainframes before or after committing crimes occurs. As a result, the lack of on-site evidence and the inability to recover the case greatly increased the difficulty of police detection. Ensuring the security of ATM monitoring equipment is a basic prerequisite for security systems. Embedding anti-vibration, anti-movement and anti-fire sensors in the ATM monitoring host is a good way to solve such problems, such as integrating the vibration monitor in the monitoring host (anti-movement, anti-vibration and anti-tamper), and temperature alarm (fire prevention )Wait.
If you want to avoid cases of lost packets, robbery, etc., then the bank's ATM screen currently has prompting functions. However, suspects often use false notices to cover the screen and cause cardholders to lose vigilance. Another important factor is that prompting often occurs. After the card, at this time, the piracy behavior may have occurred, and there is also a factor that most cardholders often do not carefully look at the prompt screen and insert the card directly. The prompt warning of cardholders’ various fraudulent practices after entering the self-help area is the most effective way of propaganda. Propaganda methods, building an independent voice and visual alert system.
Now let's talk about how to promptly remind relevant personnel to perform on-site disposal if an abnormal situation occurs. SMS alarm is a very effective means of alert notification. It can promptly inform the relevant personnel what kind of level of alarm information occurs where, to facilitate the judgment and disposal, the best solution is to install SMS alarm module.
Above, we talked about the key points to be guarded against by several key ATM monitoring and security aspects. The following are the actual analysis and answers to the four main problems of ATM monitoring:
Question 1. What should I do if I lose my ATM or suddenly lose my power because I press the wrong button while taking the money? If the ATM button crashes or suddenly crashes due to pressing the wrong button, Farland Technology's self-developed Host Status Monitor can easily handle this issue. The host status monitor will use its own power storage to restore the ATM's work. In case of power failure and crash, it will also send an alarm signal. This will not only solve the actual problem, but also restore the security and return the work. The staff provided a convenient and quick working environment, which was a three-fold effort.
Question 2. The monitoring ATM machine also gave me the password when I took the money. My bank card is not safe. What should I do? The embedded professional hard disk recorder, HRC-168 ATM, has successfully solved this problem. When the monitoring host records the cash outlet, it can effectively “block†the ATM keyboard area according to the actual situation. However, the automatic teller machine can work normally, and the bank card password of the payee can not be disclosed, which can also be said to serve two purposes.
Question 3: What should I do when suspicious people are wandering around when withdrawing money? What should I do if suspicious individuals are found to be in the vicinity when withdrawal workers are withdrawing money? Let's first look at a real case: Zhang, a resident of Nanjing, who lives in Nanjing, Jiangsu Province, according to him, stated that once he took money at an ATM, he always felt that he was staring at me on the right, and I aimed at it with Yu Guang. A few times, there really was a person. The man wore a cap and a black windbreaker. The hat was very low. I didn't see his face clearly, but I knew that from the moment I entered the cash machine, he had already stared at me. For a long time, and my whereabouts were very suspicious, I was very uneasy in my heart, but when I took the money and found the "emergency button" on the ATM, I did not hesitate to press it down, and the alarm started, the local The police quickly rushed to capture the man. According to the local police officer's review, the man was the criminal suspect who committed crimes in Nanjing many times. Finally, Zhang was pleased to say that he did not expect that the small button was really useful. .
This button is designed by Fartor Technology and is designed to solve this type of problem. After Yuantuo Technology designed an “emergency button†on the ATM, when the withdrawal staff found suspicious persons around, they could directly press the button. Move the "emergency button" to activate the alarm and escape the predicament.
Question 4, when I just walked out of the cash machine, my money was robbed, surveillance video can also monitor the effective data? The general monitoring can only be limited to monitoring, and the scope is limited. Once you get out of the cash machine, you lose the monitoring scope. So you have to use the pinhole video with environmental monitoring. Even if you get out of the cash machine, the money is actually grabbed by us. Monitor the panorama of the host computer and record it down. So you don't need to worry about everything.
The above mentioned is to include the practical difficulties and possible solutions currently facing the field of ATM security. Overall, it is to change the traditional single video monitoring ideas, make full use of various types of sensors to establish early warning, on-site deterrence, and equipment safety. , case control, power delivery system. Realize the organic combination of technical prevention, physical defense, and human defense, effectively and efficiently create a safe withdrawal environment, combat professional crimes of ATM machines, protect the interests of cardholders, maintain the social image of banks, and ensure the order of financial payments. We believe that with the joint efforts of financial regulators, bank users, security service providers, and equipment manufacturers, we will be able to solve this industry problem.
