ATM security still has room for improvement

ATM ATMs are an important bargaining chip for banks, and they have positive significance in the financial market and convenience. However, their own security measures still need to be continuously improved. Due to the frequent occurrence of crimes, the security requirements of ATMs are getting higher and higher. From the past cases, the role of video surveillance and intelligent surveillance in the development of ATM security is only temporary. With the advancement of science and technology, There are endless criminal means, and a single plane monitoring cannot meet the needs of development. The market urgently needs a three-dimensional, multi-sensor integrated video surveillance system.

ATM operation requires video surveillance and escort With the rapid development of China's economy, ATM has been widely popularized in China. ATM teller machines have become an indispensable part of people's daily lives. According to the “2013-2017 China ATM Machine Industry Market Forecast and Investment Forecast Analysis Report”, China has an average of about 220 ATMs per million people, and the distribution of ATMs is extremely uneven, which is lower than the world’s average of 1 million people. The level of 315 ATMs is far lower than the level of more than 1250 ATMs per million people in the United States and Japan, and since 2000, the total number of ATMs in China has reached an annual average of 24.62%. The compound growth rate has grown at a rapid rate, and there is huge room for market development.

We have to admit that the emergence and use of ATMs has played an active role in facilitating the people’s life and activating the financial market. However, due to the characteristics of automatic withdrawals and unattended ATM machines, criminal cases and economic disputes involving the use of ATM machines have recently been seen in various media and newspapers. Therefore, how to ensure the safe operation of ATMs, prevent and reduce the risks of banks and depositors, crack down on criminal activities using ATMs, and fully protect the interests of banks and users, has become an urgent issue that the security industry must solve.

To establish a feasible monitoring plan, we must combine the ATM machine's own operating characteristics and its use environment in order to ensure the safety and stability of the system. Comprehensive operating conditions of various ATM machines can be derived as follows:

ATM machines operate for 24 hours, which places great demands on the stability of the monitoring equipment. Most ATM machines are unattended. Therefore, comprehensive consideration should be given to various security risks, and timely records can be obtained when there are abnormalities. Because ATM operates under both day and night conditions, it imposes higher requirements on the minimum illuminance of the associated cameras; ATMs are mostly installed in busy streets, and the detection distance, sensitivity, and anti-jamming measures of the detectors are proposed. Higher requirements; there are many types of ATM machines, and their structures and installation methods are all different. At the same time, they must be concealed during installation. Therefore, the size and installation position of cameras and detectors are greatly limited.

Bank ATM monitoring alarms should be developed in the direction of digitization and centralized networking. Such a high starting point and forward-looking monitoring model is more suitable for the rapid development of bank ATM business, strengthening ATM management, avoiding investment waste, and ensuring the normal security of bank ATMs. The use of aspects has very real meaning.

ATM monitoring still needs to improve ATM ATMs as banks' competitive business outlets, and their security requirements are relatively high. It turns out that many ATM cases have occurred, and video surveillance and intelligent monitoring have been used for the development of ATM security. A certain degree of escort effect, but with the advancement of science and technology, criminals modifies the modus operandi, a single plane video surveillance monitoring method obviously can not meet the development needs, the so-called "high road height," then ATM monitoring needs It is imperative to create a three-dimensional prevention and control system with multiple sensors as the core and video surveillance as the backing.

Although the current ATM monitoring has become more common, there are still many problems that have caused problems after the incident has been solved.

◇ Intelligent monitoring is not a smart ATM has always been the focus of monitoring objects, the bank also invested a lot of money to monitor the monitoring system, at any time will be tens of thousands, more than an ordinary set of monitoring systems to several times or more, but often in the key It did not play its due role. The upgrade of smart products will come out, but the smart monitoring of the upgraded products is not as much as advertised. The most prominent thing is that “alarms for abnormal conditions are discovered in a timely manner” has become a legend, and intelligent monitoring is not smart. The reason lies in the realization of intelligent monitoring, and it needs to satisfy multiple harsh operating environments and preconditions. Such as high-definition cameras can not withstand the impact of bad weather, mirror reflection and water spray and other external factors, resulting in video footage destruction, affecting the analysis results, and other intelligent monitoring software in the application is vulnerable to the impact of light and perspective, omission and Misinformed accidents happen from time to time. When criminals wear masks to perform ATM crimes, video surveillance and intelligent surveillance can only be blindfolded. When an accident is known, the criminals have already run away, and at the same time, surveillance provides video recordings. It is not the actual appearance of the culprits. It is also easy to mislead the police to solve the case. In addition to emulating masks, even if criminals use stolen objects to steal, it is not as timely as possible.

â—‡ High-cost ATMs are used as the key monitoring object. 24-hour operation requires high stability of the monitoring equipment. Under both day and night conditions, the minimum illuminance of the supporting cameras is high; most ATM machines are installed. In the downtown area, the detection distance, sensitivity, and anti-jamming measures of the detector are required to be high. This series of requirements means the price. When banks compete for quantity, the precision of the monitoring equipment will not catch up with the demand. After the accident, surveillance video was not clear and other issues seriously affected the progress of the case.

Zhao Ce, director of the blue interstellar market, said in an interview: “A simulated camera monitor often encounters problems. When it comes to searching for something, the clarity is not enough. You need to see the person’s face, including banknotes. For example, the frame rate can not keep up with the speed of banknotes.The 10,000 yuan banknote has 100 sheets of 100 yuan. If you use a banknote counter, it is probably a 5 second process. There is a request in this box, and you need to clear this information in an instant. It is recorded and every trip can be clearly seen. The requirements for the camera are very high."

Prof. Yang Lei from the Department of Digital Media Technology of Communication University of China also stated that “ATM monitoring is very demanding for cameras. If high-speed cameras can be used in the security field, many problems will not exist. Of course, its cost will be very high, and it may be a half hour. No one used it."

压力 Pressure on storage space From the current situation of bank monitoring, the front-end transmission bandwidth is mostly 2 megabits, and some are even shared with the service network. At this time, the front-end is fully HD, the camera is also HD, and the VCR is also HD. Save the video to ensure the effect, at least 4 megabytes of video stream must be saved. Too low will affect the video quality. Therefore, the storage space is very demanding. At the same time, the data bandwidth is more limited on large data networks.

Face recognition and big data are the implementation and upgrading of security protection in the financial industry in the future, and it is one of the important basic tasks for the development of the financial industry. With the growing application of security monitoring in the financial sector, market demand has continued to expand. The functions of the original security system could not meet the needs of the market. As a result, the upgrade of the financial security system is a general trend. Financial security breakthroughs the technical bottleneck towards the era of high-definition intelligent networking.

The concept of security is not just monitoring, it should be applied in all aspects. In the bank, the security business should be combined with the bank's business considerations, ATM monitoring should be introduced into the real name system, for example, the second generation of identity cards applied to the ATM machine, to prevent criminals from stealing other people's bank cards to withdraw money. He believes that real-name face recognition is the direction of future banks, and with the advent of the era of big data, video data ranks first in the data, it will bring many problems, transmission problems, storage problems, processing problems, need more The entry of high-tech personnel and the resolution of these issues will enable financial security to develop better.
