Patent Application
20070290033
Banking automation equipment is a financial service-related automation machine capable of supporting simple financial services, such as deposits or withdrawals, regardless of time and space, without the aid of a bank clerk. The banking automation equipment is configured to allow clients to process automated transactions by themselves, such as the withdrawal or deposit of cash (bills), using a medium such as a card or a passbook.
Recently, since most companies have adopted a five-day work week system, people frequently tend to use banking automation equipment, such as ATMs or CDs, instead of visiting a bank in person. Consequently, the installation of banking automation equipment has gradually expanded, and the number of banking automation equipment installed has increased more and more. Banking automation equipment is currently implemented such that it can be used in processing a variety of additional functions, as well as main services of the bank, and is continuously being developed to enhance bank competitiveness and client satisfaction.
In such an apparatus as banking automation equipment that prevents other people from illegally connecting to and using a banking system, only authorized users can normally operate the equipment. To this end, a password is given to each user, and a user is required to input the password before performing a financial processing function. It is confirmed whether the inputted password is identical to a previously registered password, and the next step of the function can be processed only if the two passwords are matched with each other.
However, while a user inputs a password in the currently used banking automation equipment, financial transaction information, including the client password, can be stolen through a pin-hole camera installed in the banking automation equipment or booth. Through the stolen password, as well as an illegally copied card or an illegally obtained card number, improper withdrawals or illegal credit transactions can be performed from a client's account.
In other countries, such crimes are extremely serious and increase year-by-year, and every effort is made to prevent these crimes. However, cases of practical use or application have not yet been reported.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Generally described, a method and an apparatus are directed to provide banking automation equipment that prevents the leakage of client information using infrared light-emitting elements attached on the periphery of the PIN pad of the banking automation equipment. The PIN pad is configured to operate the infrared light-emitting elements at regular intervals when a user enters a password so that photo images of a client password and financial transaction information cannot be correctly captured via a camera.
According to an aspect of the present invention, there is provided a method of preventing leakage of client information in banking automation equipment, which comprises the steps of receiving a selection of a financial transaction from a user when insertion of a passbook or card is recognized by a passbook/card recognition unit; operating an infrared light-emitting unit to emit infrared light using infrared light-emitting elements of a PIN pad; determining whether the infrared light-emitting elements operate normally by an infrared light sensor; receiving a password for the transaction from the user; informing a manager of the banking automation equipment of an abnormal operation thereof if it is determined that the infrared light-emitting elements operate abnormally; and stopping the operation of the infrared light-emitting elements and proceeding to conduct the transaction if the step of inputting a password is terminated.
In order to control the aforementioned steps of the present invention, there is provided banking automation equipment including a passbook/card recognition unit, a display unit, a printing unit, a check/cash deposit and withdrawal unit, a storage unit, and a communication unit. The banking automation equipment of the present invention comprises a key input unit, including a PIN pad provided with infrared light-emitting elements; an infrared light-emitting unit for amplifying infrared light and outputting the amplified light toward the PIN pad; an infrared light sensor for sensing the infrared light to determine whether the infrared light-emitting elements operate normally; and a control unit for controlling the aforementioned components and causing infrared light to be emitted from the infrared light-emitting unit, when a user inputs a password, to prevent an action of stealing a client password and financial transaction information using a camera.
Further, there is a PIN pad for preventing an action of stealing a client password and financial transaction information using a camera, which comprises a PIN pad body for encoding the user's password and performing a key operation; a peep-prevention shield installed on the periphery of the PIN pad body to hide a motion of a user's hand; and a plurality of infrared light-emitting elements mounted on an upper surface of the peep-prevention shield.
The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings. However, the present invention is not limited to the preferred embodiment thereof set forth herein, but can be implemented in different forms. Rather, the preferred embodiment is merely provided to allow the present invention to be completely described herein and to fully convey the scope of the invention to those skilled in the art. In the drawings, like elements are designated by like reference numerals.

The PIN pad body 110 is an ordinary input device for receiving a user's key input and performs a variety of functions related to input operations, such as a function of encoding a password or transmitting input data, if a user inputs the password when user authentication/confirmation is required or the user inputs transaction information, such as a payment amount, in a financial transaction or the like through the buttons of the keypad provided on the PIN pad body 110.
The peep-prevention shield 120 is made of a material through which infrared light cannot pass and is vertically installed along the periphery of the PIN pad body 110. The peep-prevention shield 120 serves to hide a motion of a user's hand, which is used to input the password, so that a camera cannot take a picture of the motion.
In addition, the peep-prevention shield 120 functions as a portion on which the infrared light-emitting elements 130 are installed. Dozens of fixing holes are formed on the upper surface of the peep-prevention shield 120 so that the infrared light-emitting elements 130 can be fixed into the respective fixing holes. That is, the infrared light-emitting elements 130 are configured to receive amplified signals and electric power from a control substrate in the equipment through the respective fixing holes.
Each of the infrared light-emitting elements 130 emits infrared light at regular intervals, like strobe light, to allow the camera not to automatically adjust luminance and thus to prevent the leakage of a password. Since a human being cannot sense infrared light with his/her naked eyes, the infrared light does not affect the user. However, since a pin-hole camera or film camera used in the crime senses widely an infrared light band, a flash of the camera is difficult to automatically adjust or change the luminance of the camera due to the influence of the infrared light. Accordingly, a lighting interval of the infrared light-emitting element 130 is preferably set to be faster than the speed of the flash in an ordinary camera.
Further, a diffusion-type infrared light-emitting diode array with low electrode contact resistance and high light-emitting efficiency is preferably used as the infrared light-emitting element 130. The diffusion-type infrared light-emitting diode has a light-emitting efficiency, which is 20% higher when the light travels straight and is 80% higher when the light diffuses, as compared with that of a general light-emitting diode where lights are converged on the center and travel only in a forward direction. Furthermore, since the diffusion-type infrared light-emitting diode is small in size and thus can be properly arranged in parallel or series, it is easy to increase the intensity of a light source. Moreover, since the lifespan of the infrared light-emitting diode is semi-permanent, there is no inconvenience of replacing electric bulbs, which is inevitable when an incandescent lamp or halogen bar lamp is employed.

In the banking automation equipment described above, the infrared light-emitting elements of the PIN pad 280 for preventing the leakage of client information operate at regular intervals similar to a strobe light before a user inputs his/her password for a financial transaction, and the infrared light sensor 220 senses infrared light to determine whether the infrared light-emitting elements operate normally. If the infrared light-emitting elements operate normally, the user is allowed to input the password. On the other hand, if the infrared light-emitting elements operate abnormally, a manager of the banking automation equipment is informed in order to smoothly operate the PIN pad for preventing the leakage of client information, thereby to safely manage the user's password.
In the present invention, it is illustrated that the infrared light sensor 220 is placed at the uppercenter of the banking automation machine, but the present invention is not limited thereto. It is apparent that the infrared light sensor can be installed at any place in the neighborhood of the banking automation equipment, as well as in the banking automation equipment, so long as the infrared light sensor can sense the infrared light emitted from the PIN pad 280 for preventing the leakage of client information.

The key input unit 310 includes a plurality of buttons for receiving basic input in order to perform transactions and converts user's input information into electrical signals to transmit the converted signals to the control unit 370. The key input unit 310 includes a PIN pad 280. If the PIN pad 280 receives a key input, the received key input is converted into electrical signals and then transmitted to the control unit 370.
The infrared light-emitting unit 360 emits infrared light and includes an oscillator (not shown) for receiving oscillation signals from the control unit 370 and generating electrical vibrations to emit a certain amount of infrared light, and an amplifier (not shown) for amplifying the infrared light outputted from the oscillator.
If the control unit 370 applies an oscillation signal to the oscillator, the oscillator generates a certain amount of infrared light. Subsequently, as the amplifier amplifies the generated infrared light, the infrared light-emitting elements 130 of the PIN pad emit the amplified infrared light.
The infrared light sensor 220 senses absolute physical quantities of the infrared light generated from the PIN pad 280 to determine whether the infrared light-emitting elements 130 of the PIN pad 280 operate normally.
Generally, there are a variety of elements that can detect the absolute physical quantities of infrared light, and it is preferable to use a focal plane array (FPA)-type infrared light-sensing element.
The FPA-type infrared light-sensing element comprises an optical lens, a focal plane array connected to the optical lens, and a signal processor connected to the focal plane array. The optical lens concentrates infrared light signals from an object image onto a surface of the focal plane array. The focal plane array has a plurality of detectors and converts the received infrared light signals into electrical signals corresponding thereto. The signal processor receives the electrical signals outputted from the focal plane array and converts the electrical signals into signals suitable for transmission to the control unit 370.
Accordingly, if a signal indicating that the infrared light sensor 220 has sensed infrared light is sent to the control unit, the control unit 370 determines that the PIN pad 280 for preventing the leakage of client information using the infrared light-emitting elements 130 operates normally, and the user is then guided to input the password.
First, a user inserts a passbook or a card into the banking automation equipment, and the passbook/card recognition unit 320 recognizes the passbook or card (step S402). Then, the user selects a financial transaction through the key input unit 310 while confirming the contents displayed on the display unit (step S404).
If a transaction is selected, the control unit 370 actuates the infrared light-emitting elements 130 to generate infrared light (step S406). That is, if an oscillation signal is applied to the oscillator of the infrared light-emitting unit 360, the oscillator generates a certain amount of infrared light. Then, the amplifier causes the generated infrared light to be amplified and the amplified infrared light to be emitted through the infrared light-emitting elements 130 of the PIN pad.
If infrared light is emitted through the infrared light-emitting elements 130, the infrared light sensor 220 senses the infrared light to determine whether the infrared light-emitting elements 130 of the PIN pad operate normally (step S408). If it is determined that the infrared light-emitting elements operate normally, the user inputs a password according to the directions for use (step S412). If it is determined that the infrared light-emitting elements operate abnormally, a manager of the banking automation equipment is informed through the communication unit (step S410), and then the user inputs a password (step S412).
If the input of the password is completed, the operation of the infrared light-emitting elements 130 of the PIN pad is stopped (step S414), and the control unit 370 allows the banking automation equipment to connect with a host computer of a bank through the communication unit 350 such that the financial transaction can be performed while the relevant data are exchanged between the banking automation equipment and the host computer (step S416).
Although the present invention has been described and illustrated in connection with the specific preferred embodiment, the present invention is not limited thereto and is defined by the appended claims. Therefore, it will be understood by those skilled in the art that various modifications and changes can be made thereto without departing from the spirit and scope of the present invention defined by the appended claims.
According to the present invention as described above, there is an advantage in that an apparatus for preventing the leakage of client information using infrared light-emitting elements is attached on the periphery of the PIN pad of the banking automation equipment to operate the infrared light-emitting element at regular intervals when a user enters a password, so that damage due to actions of stealing a client password and financial transaction information using a camera can be prevented or minimized.
Further, the reliability of financial transactions can be enhanced due to reinforced security of the banking automation equipment, and an effect of highlighting the image of a differentiated financial institute can be achieved.
While illustrative embodiments have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
