There was no security measure to sanction. 1 (b), in order to use the IC chip 10 of the IC card, a keypad 130 provided on the IC card is used So that the IC chip password must be inputted through the IC chip.

In other words, the conventional IC card can use financial services such as traffic and sale by using an IC card even if it is not the owner, but the IC chip security card 100 of the present invention can input the IC chip password The IC chip 10 itself can not transmit a signal to the reader, so that it is possible to greatly improve the security in using the conventional IC card.

A more detailed description of the configuration and role of the IC chip security card 100 of the present invention will be described below with reference to FIG. 2 to FIG.

For reference, the shape, size, and position of each component of the IC chip security card 100 shown in FIGS. 1 to 3 are used for describing the function of the IC chip security card 100 according to the present invention. And may have any number of shapes, sizes, and positions on the IC card that are capable of installing the components.

2 is a block diagram for explaining a structure of an IC card having an IC chip security function according to an embodiment of the present invention.

2, the IC chip security card 100 of the present invention includes an IC chip 10, an IC chip switch 110, an IC chip switch controller A keypad 130, a memory 140, a controller 150, a display unit 160, a battery 170, and the like are formed on the surface and inside of the card . The material constituting the card is not particularly limited, but is preferably made of a polymer material in consideration of flexibility and the like. Examples of the polymer material include PVC, PETG, PE, PP, PC, and the like.

The IC chip stores specific information of a user and includes an antenna capable of performing an interaction such as transmitting specific information in a contact / noncontact close contact with an external reader (card terminal). The IC chip switch 110 receives the control signal of the controller 150 to enable the IC chip to be in an active state or an unusable inactive state. When the IC chip switch 110 is closed, the IC chip is activated and the IC chip switch 110 is opened, the IC chip becomes inactive.

For reference, since the IC chip switch 110 is normally off, the IC chip remains in an inactive state.

In addition, the memory 140 stores the IC chip password. The IC chip password is issued and stored in a bank or a card issuing organization with the consent of the card owner when the card is issued, and the keypad 130 As an input means capable of receiving a password from a user, it plays the role of receiving letters, numbers, symbols, and the like.

The battery 170 supplies power to operate the components of the IC chip security card 100 of the present invention. The battery 170 can be a thin-film type primary battery or a secondary battery that can be installed in the card. , Particularly a secondary battery which can be charged.

The control unit 150 includes a circuit unit including a microprocessor for controlling the IC chip on / off of the IC chip security card 100. Upon receiving a password from the keypad 130, If the two passwords match, the IC chip switch 110 is turned on to switch the IC chip to the active state so that the user can use the IC chip security card 100 . If the two passwords do not coincide with each other, the control unit 150 does not transmit any IC chip switch control signal or transmits a switch-off control signal to the IC chip switch controller 120 to keep the IC chip in an inactive state Disable the IC card.

More specifically, the control unit 150 transmits an IC chip switch-on control signal to the IC chip switch controller 120 when the two passwords match, The chip switch controller 120 turns on the IC chip switch 110 only. The IC chip switch controller 120 may be included in the IC chip switch 110 or may be included in the controller 150 or may be separately disposed between the IC chip switch 110 and the controller 150 .

On the other hand, the IC chip, which is normally inactive as described above, is switched to the active state and then returns to the inactive state after the user completes the necessary work, so that the security of the IC chip is continuously maintained. The chip switch 110 must be controlled to be turned off again. Thus, the IC chip security card 100 of the present invention automatically transmits a switch-off control signal from the control unit 150 to the IC chip switch controller 120 after a preset period of time has elapsed, The control unit 150 automatically transmits a switch-off control signal to the IC chip switch controller 120 after performing a predetermined number of interactions or a button on the keypad 130 By switching the IC chip to an inactive state by transmitting a switch-off control signal to the IC chip switch controller 120 in the control unit 150 when the user clicks one of the buttons on the keypad So that the IC chip can be kept in an inactive state.

The display unit 160 displays confirmation information indicating whether the IC chip switch 110 is turned on or off or whether key input is performed on the keypad. The display unit 160 may be an LED or beeper IC Depending on the type of chip security card, it can be set up in various ways.

2 is a block diagram for explaining the present invention when the IC chip is of an active type (a battery is required for the IC chip). When the IC chip is passive type (operates by receiving power from the reader) The IC chip switch 110 may be installed at another position where the activation of the passive IC chip can be controlled. That is, it is not important whether the IC chip is passive or active, and the active / inactive state of the IC chip can be controlled through the structure of the present invention.

3 is a flowchart illustrating a security method of an IC card according to an embodiment of the present invention.

3, in the security method of the IC chip security card of the present invention, when the IC chip security card is issued by a bank or a card issuing agency, the IC chip password desired by the owner is accepted in memory And stores the IC chip security card (S101).

After issuing the IC chip security card in which the IC chip password is stored, the user inputs a password through the keypad installed on the IC card (S102).

When the user inputs a password through the keypad, the controller installed in the IC chip security card compares the password received from the keypad with the IC chip password stored in the memory (S103).

When the result of the password comparison is identical, the control unit transmits a switch-on control signal to the IC chip switch controller to close the IC chip switch to switch the IC chip from the inactive state to the active state (S104).

If the result of the password comparison in the control unit does not match, no signal is transmitted or a switch-off control signal is transmitted to the IC chip switch controller to keep the IC chip in an inactive state so that the IC card can not be used (S105).

After the IC chip switch is turned on and the IC chip becomes active, the IC chip performs a predetermined number of times of interaction with the reader after a predetermined period of time has elapsed, The control unit sends a switch-off control signal to the IC chip switch controller to return the IC chip to the inactive state (S106) .
