ATMs have brought much convenience to financial transactions but security safe hazards and burdens also come along with. Since the public and financial units hadn’t paid enough attention on the safety of ATMs, financial losses caused by that are far beyond the investments on safety. Therefore, in order to make a balanced mechanism between safe and burden to solve the security problems of ATM, we must carefully plan the security architecture of ATMs. The architecture must consider the following factors:
1. Ability of surveillance function；
2. Linkage alarm function；
3. Anti-card theft and password theft functions；
4. Anti-crash and anti-outage functions；
5. Software and intelligent analysis functions；
6. Network management function；
7. Vibration detection function；
8. Human activity detection function.
According to the eight consideration directions, we can generally describe the security architecture of safe application of ATM to indicate the content of brilliant safe surveillance function of ATMs.
We can see the following functions under the ATM intelligent security architecture:
．4-5 channels surveillance recording mode to provide proper digital compression video playback and alarm pre-recording function；
．Use day night video camera which can auto adjust according to environment and light changes and 360-degree panoramic video camera；
．Analysis and recognition of video surveillance and card loading and passwords auto shielding functions which are very necessary during operation；
．Analysis of human body proximity mode and surveillance and alarm of people proximity or tracking；
．Lens shielded (painting or paste something) and exceptional actions as well as outage alarm functions；
．Auto recording adding note process and raising the alarm functions.
How to prevent rampant ATM password theft crimes? Advantages and disadvantages of all kinds of technical measures:
Currently, solutions on anti password theft mainly have two types:
1. Anti password theft solution based on video recognition
This solution relies on many factors. For example, whether image definition reaches the basic demands of video analysis； whether the images are influenced by human (including taking an umbrella or wearing a helmet, scarf or mask or small pieces of reflective sheeting) or destructed； whether illegal posts with polarizing ability are used； whether the image analysis recognition algorithm is accurate or not. Only when several requirements be satisfied at the same time can it achieve intelligent analysis. Therefore, intelligent image recognition system requires very ideal and harsh conditions, but in actual ATM withdrawing environment, these conditions can hardly exist. In this respect, feasibility of intelligent surveillance system based on video is very poor and so as to the actual results.
2. Anti-password theft solution based on laser ranging principle
Bank card password theft crimes have a common feature, which is to install an extra device (password theft equipment, false keyboard, etc) on the ATM. Any extra installation means that the spatial heights of some important positions (card slot, keyboard, etc) have been changed. Use high-precision ranging sensor to detect the spatial heights of these sensitive positions in real time, you can judge that whether password theft equipment is installed on the card slot. Therefore, it can emit the alarm and pre-warning during installation and gain time for stopping and arresting criminals.
This system uses phase laser ranging nodule to achieve high-precision laser multi-point ranging which can form a laser protection net around the card reader. Since the device is installed in front of the self service equipment, it is not only easy to set but also with good concealment. Moreover, it does not need to break the self service equipment and its installation place is not fixed which means that it can be installed away from the ATM within the distance between 0.05M—30M. In addition, laser light path of the equipment has a wide detection range and it isn’t easy to be affected by environment and electromagnetic interference and thus false alarm and omission problems of traditional equipment can be solved effectively.
The above are the safe application points of establishing the new generation ATM. There is no doubt that requirements on safety are endless. Under the condition that ATM crimes keep increasing, requirements on safety consideration and methods should be －d constantly. Yuantuo Tech reminds you that you should pay attention to other forms of the ATM other than ATM entity. Networking ATM also generally becomes the mode of financial transaction. Suggestions on networking ATM safety is that you had better access through the official website of the financial bank or linked website that has been verified safe with enough popularity. Do not link any unknown websites to avoid fraud risks. Meanwhile, you should upgrade anti virus software regularly. Avoid receiving any unknown emails and do not use PC to access network ATM in public. After using the chip card, do not leave it in the chip card reader and thus to avoid any risks. By means of these software and hardware as well as brilliant safe mechanisms of self protection, we believe that there will be a reliable and safe financial ATM application environment in future.
