Image Recognition Cash Withdrawal System {IMAGE RECOGNIZING CASH WITHDRAWING SYSTEM}

The present invention relates to an image recognition cash withdrawal system and a method thereof, and to a cash withdrawal system having an image recognition means, as well as can be applied by adding an image recognition means to an existing system.

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 may cause errors in recognition, and it is necessary to integrate data into the system after inputting the data of fingerprint or iris required for authentication in advance, and installation and maintenance costs are considerable, and time and troublesome use and authentication are very significant. 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 provision in case of withdrawal.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to provide a means for allowing a transaction to be made after reading a user's impression by image recognition appropriately recorded and stored, An object of the present invention is to provide a means of interworking with an existing system.

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 so as not to obscure the subject matter of the present invention.

1 is a control block diagram according to an embodiment of the present invention. As shown, the present invention is a control unit 110; and the ROM 120, the recording unit 130, the input unit 140, the display unit 150, the warning unit 160, the image sensor unit 170, CCTV linked thereto 180 and cash in and out means 190. The control unit is responsible for controlling the overall operation of the present invention, and is driven according to the execution program stored in the ROM. The execution program recorded and stored in the ROM may be added, deleted, and changed as necessary, and for this purpose, the execution program may be configured as an element capable of deleting and rewriting data stored such as an EPROM.

The input unit is a means for inputting necessary information by a user using an ATM machine, which preferably includes an input means and a user information reading means. In general, the input means is generally composed of a panel in the form of a keyboard, which is a combination of a series of letters, numbers, or symbols, and may be in the form of a touch screen that is commonly used as necessary. In addition, the user information reading means provided with an input unit includes means for recognizing the information by inserting or contacting a medium containing user information such as a name and a password of a registered user through a cash card or a credit card. This is preferred.

The display unit displays information for convenience of the user using the cash withdrawal system, for example, a phrase for facilitating a user interface such as "insert a card", as well as a series of information input by the user. And a series of instructions to guide you through the process of withdrawing cash. In general, the LCD window is configured, and CRT and other suitable devices can be selected and configured as necessary.

The warning unit performs a function of notifying the user of a suitable warning by voice, sound or warning lamp so as to correct an undesirable procedure during the operation of the image recognition cash withdrawal system of the present invention. E.g. If the user's face is not image-recognized to the extent required by the present invention, then the face of the mask, sunglasses or hat or other user is identified so that the user's face is properly exposed to meet the needs of the present invention. It is responsible for notifying, by voice, sound or warning, appropriate warnings or notices for the purpose of removing the elements that are intrusive.

The image sensor unit is a means for reinforcing the post-security for the user of the image recognition cash withdrawal system of the present invention, means for determining whether the user's face is exposed to the degree required by the present invention. Whether it is exposed to the degree required by the present invention should not be a degree that can not recognize the user's face shape with a mask, sunglasses or a hat, etc., as well as it should be clear that it is the face shape of the exposed person as a result of image recognition. Is that. This can be achieved by employing an appropriate image sensor that meets the needs of the present invention.

Normally, the image sensor is used for various purposes such as detection of a thermal object such as a human body, human body detection, shape recognition, non-contact thermometer side, but in the case of the image sensor required for the present invention, infrared image is used for human body detection and shape recognition. It is desirable to employ a sensor. In general, the infrared image sensor is capable of detecting features by heat distribution, and thus it is possible to accurately obtain information on a human body, a heat source, and a shape with a simple system compared to visual image processing. On the other hand, infrared image sensor is classified into quantum type and thermal type, and quantum type has a disadvantage in that it has high sensitivity and responsiveness because it uses photoconductor or photovoltaic effect, but it is expensive to require cooling of the element part. In this case, there is a problem in that the sensitivity and responsiveness are somewhat insufficient when the infrared ray is converted to thermal energy to be used for image detection purposes. However, in the case of the present invention, the meaning of the auxiliary means for securing the security of the user after the fact is large, and the screen storage by CCTV is performed in parallel with the image reading, so that the purpose of the invention is used even if any type of infrared image sensor is used. There seems to be no difficulty in achieving it. On the other hand, it is common to add a signal processing IC or the like for processing an image signal. Typically, the signal processing IC includes an OP amplifier constituting a band amplifier for amplifying a small signal.

The CCTV is a means for providing a screen that can be recorded and stored in a certain storage medium by photographing the shape of the face, so as to confirm the identity of the user after the fact. In addition to the image sensor, it is an essential device for identifying an illegal user's identity, and it is conventionally installed to identify a user's shape through a minute lens hole in a portion of an upper portion of an ATM machine. On the other hand, the recording unit provides a means for storing the user screen photographed by the CCTV.

The cash withdrawal means is a means for withdrawing or depositing cash according to the control signal of the controller when the preliminary step necessary for withdrawing cash, such as user information recognition, is completed. It is usually equipped with means for printing and outputting deposit and withdrawal slips.

Figure 2 shows a schematic diagram in accordance with an embodiment of the present invention is linked to an existing ATM. As shown, the image recognition cash withdrawal system of the present invention interlocks a PC 230 in which an existing program for executing image recognition and reading is incorporated in the existing ATM machine 210, and the image sensor unit 220 is provided on the PC. It can be implemented by interworking. In addition, if necessary, after reading the image recognition information, a separate mass storage device 240 capable of storing the information can also be operated in conjunction with the PC. The information recorded in the mass storage device is controlled by the PC and can be deleted at regular intervals.

3 schematically illustrates an image recognition procedure according to an embodiment of the present invention through a flow chart. As shown, the operation example of the present invention will be described in detail. The image recognition of the ATM machine of the present invention includes a card insertion step (s310); and an image recognition step (s320); and an image reading step (s330); and a screen storing step (s340).

According to the user's request for cash withdrawal using the image recognition cash withdrawal system, the image recognition cash withdrawal system of the present invention starts to operate (s300) and at the same time, the user can use a cash or credit card in which the user's read information is input. The card insertion step s310 is inserted into or in contact with the cash withdrawal system. In this case, when the user attempts to withdraw cash without omitting the above procedure, a warning is issued to inform the user that the card should be inserted through the warning unit 160 (s311). When the basic information necessary for the reading of the user is provided to the cash withdrawal system by insertion or contact, the process proceeds to the next image recognition step s320. In the image recognition step, the face shape of the user is recognized by the image sensor, and it is checked whether the user is located within a range that the image recognition sensor can detect. Even in this case, when the user is located outside the range that can be recognized by the image recognition sensor, the warning unit 160 issues a warning to call the user's attention and accordingly reaches the case where the user's image recognition is possible. The process proceeds to the next step of image reading (s330).

In the image reading step, it is a step of determining whether or not the face of the user is exposed to the extent required by the present invention by a control unit driven according to the execution program stored in the ROM or a PC. . In general, image processing extracts a specific area by using a differential image between frames, or by accumulating a background and cutting out only the areas in which changes have occurred. Usually, since the temperature of the human body is considerably higher than that of room temperature, a constant temperature is extracted. By extracting the higher pixel area from the pixel area of the human body, a step of reading whether or not the recognized image is not shielded by a mask, a hat or sunglasses is performed. On the other hand, when cutting out and reading an image having a predetermined temperature or more as necessary, in order to prevent a determination error caused by a plurality of users being located in the image recognition region, the cut-out image of the predetermined temperature director is divided into a plurality of image regions and read. It may further comprise a step.

If the information inputted in the image reading step and the image recognition information do not meet the standards required by the present invention, a warning is issued through the warning unit. Only if initiated can the next step be taken. If the user fails to properly respond despite the warning, the user may terminate the transaction by issuing the necessary warning through the warning unit, stopping the transaction, and simultaneously saving the user's image and storing the screen information photographed up to that point. Can be.

After the image reading step is performed, the image storing step (s340) of storing the user screen photographed by the CCTV 180 is linked to the control unit 110 and goes through the step (s340). The stored screen information may be controlled to be deleted in units of predetermined periods as needed.

When the above steps are normally executed, the image recognition step is terminated by storing the screen information photographed by the CCTV in the recording unit. Accordingly, the image recognition process is completed and the image recognition process ends (s360). Done.

The present invention described above is not limited to the above-described embodiments 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 hiding impressions by a mask or the like in the case of a fraudulent user who frequently occurs in the roots or 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.

In addition, as described above, the existing system can be linked through a PC, thereby reducing the installation cost.
