From the various cases that have occurred on ATM machines throughout the country in recent years, especially the rapid growth of ATM bank card cases since this year, there have been cases of bank ATM code theft in Beijing, Beijing, and even Shanghai where the World Expo is being held under strict precautions. , Judging from the fact that cases continue to occur in various places, it is obvious that the existing video surveillance system is obviously not playing its due role. The reason is that the entire industry relies too much on pure video monitoring and recording systems. Video equipment providers and engineering installation service providers have exaggerated the effectiveness of video surveillance. Affected by this, commercial banks and public security departments have also exaggerated the effectiveness of video surveillance. The focus of prevention and control inspections is on video surveillance equipment while ignoring other technical prevention and control methods. These factors have ultimately led to today’s severe passive situation.
From a technical point of view, video surveillance does play an indispensable role in financial security, and it also plays an important role in the after-event evidence collection and detection of ATM machine cases. However, from the point of view of its effectiveness, it can only play the role of collecting evidence after the fact and tracing the source of the crime.
There is a problem
Although the relevant state departments publicize various modus operandi on ATMs through various channels, it is very difficult for ordinary cardholders to judge whether there are abnormalities on ATMs of different brands and models. At present, the cost of police investment in some places to prevent crimes on ATMs has been greater than the investment in security equipment, but the effect is not satisfactory and the social cost is high. The resulting loss of bank reputation even exceeds the bank’s image advertising investment.
In addition, many current ATM video intelligent surveillance still have some shortcomings, mainly because the video intelligent analysis relies on many factors, such as whether the definition of the image meets the minimum requirements for video analysis, and whether the image is interfered by humans (such as umbrellas, helmets, etc.). , Scarves, portrait masks, small pieces of reflective paper, etc.) or damage, whether illegal stickers with polarizing capabilities are used, whether the image analysis recognition algorithm is accurate, etc., many conditions must be met at the same time to implement intelligent analysis, so intelligent image recognition system Very ideal and demanding conditions are required. In the real ATM cash withdrawal environment, such conditions are almost non-existent. There are not many smart video server manufacturers that can meet the above factors. Currently, only Yuantuo Technology has stable technology and comprehensive functions. , Hanwang, Hikvision and other manufacturers.
solution
Changing the traditional passive video surveillance thinking, giving full play to the effects of various sensors, establishing a comprehensive prevention and control system based on sensor early warning and backing by video surveillance, and making up for the shortcomings of the pure video surveillance system is a realistic way to solve the current dilemma .
In terms of the types of crimes currently occurring on ATMs, stealing the bank card number and password of the trader and then cloning the bank card is the most difficult to identify and prevent, and it is also the most harmful and the worst-influencing criminal method. This method has the hidden crime. , The incubation period is long, and the amount involved is large. Judging from the characteristics of this type of crime, there must be two elements: 1. Bank card number; 2. Bank card password. As long as one of these two elements is blocked, the crime will not succeed. Passwords are generally stolen by installing a camera. For bank card passwords, the location and method of installing the camera are different by the suspect (some even install a forged keyboard password shield, and the fake shield has a camera) , It is difficult to prevent.
At present, the only way to steal the card number is to install a pirate on the card slot of the ATM (the card access control system has been explicitly cancelled). The pirate is a physical device, which will inevitably lead to a change in the thickness of the card slot after installation. As long as the thickness change of the position is measured by a special device, it can be analyzed whether the card slot is abnormal. Because the laser has very high measurement accuracy, even if criminals make the pirate very thin and small, the laser ranging sensor can still accurately identify it. The laser ranging sensor can measure the thickness change of the card slot in real time. Once an abnormal change in the thickness is found, an early warning can be issued through the Internet of Things module to prevent and arrest crimes in time.
Yuantuo Technology’s anti-code theft system is independently networked to form a true Internet of Things, avoiding the drawbacks of being incorporated into the video surveillance host (video surveillance host crashes and instability are more common), even if the video surveillance host crashes, sensor warning The system is still able to perform its functions, forming a new monitoring mode with decentralized risk and centralized management.
