Abstract

PURPOSE:To improve the security function by containing a data input means, a power source, a display means, etc. CONSTITUTION:When a ten-key 4 of a data input means which is contained in an IC card base body is operated, a power source is supplied from a photocell 5 of a built-in power source, a certification number input by a card holder is executed, and an IC module 2 of a microprocessor IC checks this state, turns on an LCD 6 of a built-in display and displays a system function. When the IC card is inserted into a read/write part of the outside by seeing this display, the corresponding processing is executed, also the LCD 6 is turned off, and it is inhibited that its IC card is reused by other person. In such a way, the security function of the IC card is raised.

An integrated circuit that contains a microprocessor, memory, etc.
The so-called IC card, in which an IC module (IC module) is embedded in a card-like base, has the potential to create an extremely wide range of services by utilizing its memory function/capacity and microprocessor, so it has traditionally been used particularly in the financial field. There is an opportunity for it to be used in a wide range of fields in an advanced information society, similar to or in place of magnetic stripe cards (magnetic cards), which are widely used in the field of technology.

Needless to mention, security functions such as personal identification/confirmation are extremely important for this type of card, and a PIN number is used as a link to this.
Conventional IC cards are designed so that the PIN number cannot be exposed to the outside. - In this example, the PIN number will be given to you by the issuer when the card is issued, but when you use it for the first time, if you enter your preferred number on the external terminal device, the number notified by the issuer will disappear and you will receive a new one. The system is structured so that the PIN number is written on the card, so even the card issuer does not know the PIN number. From the next transaction, the system is opened (the gate is opened) after the card verifies the user's identity by comparing the PIN number on the card and the unique PIN number entered by the user from the keyboard of the terminal device. It was configured so that it could be processed by

However, in the conventional example described above, the first stage security function is ensured because the PIN number is known only to the person concerned, but as mentioned above, every time the IC card is used, The problem is that since the person himself/herself must type in the password from the keyboard of the external terminal, there is a possibility that a malicious person may intentionally view this or be able to detect the PIN number from the input operation. There was a point.

Next, the operation in the above configuration will be explained. Energy for the card built-in circuit is supplied from a power source such as a photovoltaic cell 5, and the card owner operates the numeric keypad 4 to input, for example, a password. The microprocessor of the IC module checks this, confirms that it is OK, and then turns it on for about 1 second.
CD6 lights up and the system opens (gate on state)
Show that it is possible. Next, when this IC card is inserted into an external read/write device and the system is opened, the card itself is configured to be released from the system openable state by an automatic erasing method. This is a measure to maintain the open state when the IC card has finished its processing operation and to be removed from the terminal device, thereby preventing accidental abuse by another person. (Each sequence circuit including the above-mentioned automatic erasing method can be easily implemented using existing technology, so a detailed explanation thereof will be omitted.) After the above processing is completed, the system is closed (shutdown) by pulling out the card.

As described above, the owner of an IC card can secretly enter a PIN number etc. in advance to set up and use the card, and after setup, the contents of the IC card itself will be stored for a suitable period of time. Since the data is automatically deleted, the security problem mentioned above can be solved.
