The present invention relates to a cash machine having a security device and a security method, and more particularly, at least two or more portions having a temperature difference in the face of a user in a transaction through the cash machine to detect the temperature through a thermal infrared sensor, and The present invention relates to a cash machine having a security device and a security method for initiating a normal transaction if it is within a set range compared to preset data but stopping the transaction if not within the set range.

The conventional cash withdrawal system uses a credit card or credit card containing personal information such as a bank, account number, social security number, name, date of birth and password for convenience and security. It is possible to withdraw cash or to use other services after reading. However, in the above case, when a password, which is a major security measure, is leaked or hacked, security loopholes have to be exposed.

In order to reinforce security loopholes, a number of fingerprint recognition systems or iris recognition systems have been proposed. However, this problem is likely to occur in recognition error and the fingerprint and iris shape required for authentication in advance to data after the problem and the installation and maintenance costs are considerable, and the use and authentication considerable time and troublesome There was a problem that took a process. In addition, in the situation where the hacking damage is frequent, the existing IC card security system is required to replace at least thousands to as many as tens of ATM machines or to replace IC cards that have already been issued. There has been a problem that needs to be replaced.

In addition, a method of recording a user's impression through CCTV for a certain period of time is used to compensate for the security problem of the ATM system and to prevent fraudulent use due to theft of a credit card or credit card. This has the advantage of ensuring rapid transactions as a follow-up measure for transaction accidents, but also in the recent frequent cases, such as fraudulent users of credit cards or cash cards hidden their impressions with a hat or mask, etc. There has been a problem that there is no measure in case of withdrawal.

Therefore, the present invention has been made to solve the above problems,

Firstly, to provide a fraudulent user's reading means through the temperature detection through the infrared heat sensor for at least two parts of the user's face,

Second, it provides a means to detect the end of the subject and to quickly measure the temperature of the target face area,

Thirdly, the object of the present invention is to provide a means for detecting the proximity of an ATM user and at the same time starting the operation of the security device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

1 illustrates a cash machine having a security device according to an embodiment of the present invention. As shown, the CCTV 101, the proximity sensor 102 and the sensor bundle (top) of the cash dispenser 100 having a card inlet 105, a monitor 104, an input means and a withdrawal means (not shown). It consists of a sensor box 103 having a 200. The sensor box 103 may be installed and function on the existing ATM machine as needed, of course, may be preferably integrated into the ATM machine. On the other hand, the ATM machine controls the function according to its own control unit, in order to be compatible with the sensor bundle 200 should be able to perform the function in conjunction with the control unit of the sensor bundle. This can be implemented by configuring a conventional network, which will not be described in detail. On the other hand, the CCTV 101 is driven according to the control signal of the central processing unit, the storage of the recording screen may be implemented through a conventional storage medium.

2 shows a sensor bundle 200 embedded in the sensor box 103 described above. As shown in the figure, the sensor bundle 200 is coupled to the left side bracket 204 and the right side bracket 205 by fastening means 206a to 206c, and the upper end of the combined bracket includes a signal transmitter and a signal receiver. The terminal detecting sensor 201 for discriminating the presence or absence of the subject is coupled by the fastening means 207, and the inside of the left side bracket 204 and the infrared thermal sensor 1 (202) for detecting the temperature of the subject and the infrared The thermal sensor 2 203 forms a predetermined angle and is fixed by an inner bracket (not shown), and the combined bracket is driven by the motor 209 through the drive shaft 208, and the lower end of the motor 209 It is configured by forming a fixing bracket 210 to enable fixing to the main body and other fixed body. On the other hand, the sensor bundle 200 may exchange a control signal and a sensor signal by forming a connector 211 and the central processing unit of the controller to be described later.

The end sensor is composed of a conventional distance sensor, it is preferable to adopt a sensor that can minimize the error according to the color of the subject. In general, the distance sensor emits infrared light through the light emitting part and detects the reflected light at the light receiving part. The end detection sensor is preferably configured as a general infrared sensor. The end sensor detects the end of the subject by detecting a point where the reflected light is not received at the end of the subject while the sensor bundle is driven upward or downward. On the other hand, when driving down, it is necessary to detect the end in advance by detecting the position where the reflected light is received by the end detection sensor. Therefore, the ATM user approaches the predetermined area to use the ATM and at the same time detects the ATM user's face downward or upward to detect the end of the head.

The infrared heat sensor 1 202 and the infrared heat sensor 2 203 are insensitive to changes in ambient temperature and need to accurately measure the temperature of a certain area of the subject. In general, the infrared sensor is used for various purposes such as the detection of thermal objects such as the human body, human body detection, shape recognition, non-contact thermometer side, but in the case of the infrared sensor required by the present invention adopts an infrared sensor used for non-contact temperature detection. desirable. In general, the infrared sensor for non-contact temperature detection is performed by sensing the energy of the surface temperature of the target object by a constant wavelength and a band width, which are generally classified into quantum type and thermal type. The quantum type has a disadvantage in that it is excellent in sensitivity and responsiveness because it uses photoconductor or photovoltaic effect, but it is expensive to require cooling of the element part.In the case of thermal type, it is detected by converting infrared energy into thermal energy. As a result, there is a problem that the sensitivity and responsiveness is somewhat insufficient. Therefore, it can be appropriately selected in consideration of the responsiveness and weight depending on the usage environment. The infrared thermal sensor detects the temperature of at least two or more points of the object to be measured at the same time as detecting the end of the subject in the terminal sensor. Therefore, the terminal sensor detects the user's head and at the same time detects the temperature of at least two of the user's faces. In other words, if the face is not normally covered with sunglasses or a mask, the temperature of the brow and the mouth of the face usually has a temperature difference of about 2 degrees. It can detect and provide data that can initiate a transaction only within a preset temperature difference.

In addition, the infrared thermal sensor 1 (202) and the infrared thermal sensor 2 (203) forms a certain angle and is fixed on the left side bracket 204, which corresponds to the need to change the temperature measurement point of the subject For that. Therefore, at least one pair may be installed by forming an angle of 0 degrees or more and 90 degrees or less in consideration of the distance between the measurement points of the subject and the distance of the subject. This will be described in detail with reference to FIG. 7 as follows. As shown in the drawing, the proximity detecting sensor 102 detects the proximity of the subject 701 and at the same time the terminal detecting sensor 201 is driven to detect the end of at least two of the sensor bundle 200. The abnormally installed infrared thermal sensors 202 and 203 operate to detect temperatures of at least two or more portions of the subject. In this case, the sensing angle α between the close distance l of the object and the sensor bundle and the at least two infrared ray thermal sensors is set in the setting unit of the sensor bundle controller which will be described later and controlled by the central processing unit. In general, the longer the proximity distance is, the larger the detection angle is, the greater the separation of at least two or more portions to be measured, so that the sensing angle between the proximity distance (l) and at least two infrared thermal sensors in consideration of the average height of the ATM user ( α) needs to be set. In this case, the proximity distance is within the sensing distance of the conventional distance sensor and can be set to the distance that the ATM user can use the ATM easily. If located, the temperature of at least two or more parts of the face shall be determined at an angle capable of detecting. This is because the size of the ATM and the location of the ATM will be different, so it needs to be set experimentally according to the application.

The motor 209 can be driven at a high speed in driving the sensor bundle 200, but precise position control is possible, and it is necessary to minimize vibrations when driving the sensor bundle, and thus, typically adopts a stepping motor. It is preferable to.

3 is a system configuration diagram according to an embodiment of the present invention. The overall configuration of the present invention through this as follows. The present invention is a cash dispenser (100) that is commonly used; and interworking with the network, the sensor unit control unit 300 consisting of a setting unit 301, the central processing unit 302 and the analysis unit 303; The motor driving unit 209a, the proximity sensor 102, the termination sensor 201, the infrared heat sensor 1, and the infrared heat sensor 2 (202, 203) for driving the motor 209 that interlocks with the central processing unit 302 are connected. Sensor bundle 200, including; and, CCTV 101 and the power supply unit 310 is composed.

The sensor bundle control unit 300 interworking with the ATM and the normal network may be implemented on a separate PCB board or may be configured as a PC if necessary. The setting unit 301 of the sensor bundle control unit may be configured to select a driving mode of the present invention, ON / OFF, transaction allowance range setting, sensor sensitivity setting, etc. according to the detected temperature, and the central processing unit may include a built-in program. According to the setting of the setting unit according to the control unit in conjunction with the ATM machine 100, as well as the motor driving unit 209a, proximity sensor 102, terminal detection sensor 201, infrared heat sensor 1 and infrared heat In conjunction with the detection sensor 2 (202,203) also controls the driving and signal.

On the other hand, the drive mode selection of the setting unit 301 may be selected by a manual operation of the administrator or by a predetermined program, which may be composed of a first mode, a second mode and a time zone mode. First, in the first mode, if you cover your face with a mask, hat, sunglasses, etc., you can stop the cash payment with the above-mentioned CCTV, but if you want to trade again, remove the cover and remove the face and take a step back to start trading again. Mode. Next, the second mode is a mode that provides a beep and video to the security personnel of the bank, but proceeds with the cash payment and shooting with the above CCTV when attempting to deal with a face mask, hat, sunglasses and the like. In this case, the provision of the beep and the projection may be implemented by transmitting a signal to the bank security officer and initiating the operation of a signal or surveillance monitor that can be detected by the security officer when it is determined that the central processing unit of the present invention is an ineligible trader. Finally, the time zone mode is a case where the bank mode is switched to the first mode after the banking hours, and the second mode during the office hours.

The motor driving unit 209a controls the motor 209 under the control of the central processing unit, but should be controlled to stop the driving of the motor in response to the end detection of the end detection sensor.

4 shows a flow of the present invention. Referring to the embodiment of the present invention as shown as follows. First, when the user approaches the ATM, the proximity sensor checks the user's proximity (401), and at the same time outputs a message (402) through the monitor, a message meaning to perform security detection as shown in FIG. At the same time, the end of the subject, ie, the head of the user's face, is detected (404) while the motor is driven up or down (403), and the motor is stopped (405) at the end detection point. The temperature of at least two or more of the portions is detected 406 through the infrared thermal sensors 1 and 2 described above.

Preferably, at least two or more of the face parts are selected around the brow and the lips having a temperature difference of about 2 degrees. The temperature detected by the at least two or more face parts is the sensor bundle control unit. After analyzing (407) whether the temperature difference is within the set allowable range in the analysis unit, it reads (408) whether the set temperature is within the set range described above, and starts a transaction (409) if it is within the allowable range and returns the sensor bundle to its original position ( 410) to complete its operation. Therefore, the allowable range set in the setting part is that the temperature of the middle part of the face is generally about 2 degrees lower than the temperature of the lip part, and thus the infrared heat sensor 1 detects the temperature of the head part and the infrared heat sensor 2 After detecting the temperature of the lip portion, the detection temperature data is analyzed by the analysis unit to control whether to start a transaction in the central processing unit according to whether or not within the set range. Eventually, the transaction will be initiated only if at least two measured temperatures are within the set tolerance range.If the user covers the lips with a mask or covers the area of the glacier with sunglasses, the transaction will not be allowed. none.

On the other hand, if it is read as not within the range set by the setting unit starts shooting (411) by the CCTV and outputs the transaction not possible message (412) as shown in Figure 6 through the monitor.

Of course, the above operation example is only an embodiment, and when the first mode, the second mode, and the time zone mode are selected and set, the warning step and the transaction retry guide through the output of the monitor, the signal tone, and the image are accordingly set. Of course, it may further include a message output step.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, according to the present invention, it is not only possible to make transactions through the ATM machine in the state of concealing the impression by a mask or the like in the case of a fraudulent user who frequently occurs in the near field or by theft. Even if it is used, the user's impression can be easily identified, which can provide an opportunity to strengthen the proactive security measures as well as the post security measures.
