Abstract

PURPOSE:To eliminate the processing of depressing of a confirming key by collating the number of digits information read from a card with the depressed number of digits of inputted identification number before confirming process of a person himself, and when they coincide, judging that identification depression is completed. CONSTITUTION:When a user inserts an IC card into an IC card terminal equipment 2, the user depresses the identification number from a keyboard 12 in accordance with guidance. The terminal equipment 2 judges automatically the number of digits of the identification number to be depressed by the user by collating the result of counting the number of digits of the identification number depressed from the keyboard 12 and number of digit information read from the card 1. Accordingly, the depression of a confirming key becomes unnecessary. When the numbers of digits of the two coincide, it is regarded by a control section 14 as the completion of depressing of identification code, and the depressed identification number is transmitted to the card 1. It is collated by a CPU in the card 1 with the identification number recorded in the card 1. When they coincide, only the result of collation is transmitted from the card 1 to the terminal equipment 2. Thus, confirmation is completed.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a PIN verification system, which uses tC cards at financial institutions, credit clothing companies, retail stores, etc. It is suitably applied to a device that performs identity verification and deposits and withdrawals of deposits and payments. The present invention particularly relates to a system for automatically checking the number of digits of a password when inputting a password for verifying the user's identity in such a device.

(Prior art) Traditionally, automatic transaction devices and cash dispensers used in financial institutions and sales companies, as well as POS (paint, of 5ales) terminals used in retail stores and department stores, use magnetic cards. The method used was to verify the person's identity, then deposit and withdraw funds and make payments. However, in recent years, mutual cooperation between financial institutions and alliances between financial institutions and credit clothing companies has progressed, and magnetic cards with multiple functions have begun to appear. Advances in microelectronics technology have also begun to make it possible to realize so-called IC cards in which microcomputers and memory elements are embedded within the card. These advances in technology have led to further expansion of mutual participation and collaboration between card-based systems, making it possible to perform an extremely wide variety of applications with a single card.

Along with this, a lot of important information has come to be recorded on IC cards, which is incomparable to the information recorded on conventional magnetic cards. For this reason, I.C.
In order to prevent theft and forgery of the +h information recorded on the card, various methods are adopted for reading and writing information recorded on the card. For example, if a special encryption method is used, an indirect addressing method is used instead of a method that directly reads/writes the memory address in the IC card, or a special key is provided, and the verification result is a match. Some systems employ methods that allow information to be read and written only to the computer. In addition, identity verification, which has conventionally been carried out by matching a four-digit personal identification number, has become possible to specify any number of digits from four to twelve, increasing security. This arbitrary PIN number is recorded in the memory within the card when the card is issued.

(Problem to be solved by the invention) However, if an arbitrary number of digits is adopted for the PIN,
When pressing the PIN, it is necessary to confirm that the PIN has been pressed, which was not the case with the conventional 4-digit fixed system. That is, if the password recorded in the card is, for example, 0 digits, the user presses the 10-digit password and then presses the end confirmation key to enter the verification operation. This not only increases the number of termination confirmation keys and increases the cost of the device, but also causes the problem that the user's operations become complicated.

This invention eliminates the above-mentioned problems and allows for more secure identity verification, with no burden placed on the user other than an increase in the number of digits pressed, compared to the conventional case of pressing a fixed 4-digit PIN code. The purpose is to provide a PIN verification method that can be used.

(Means for Solving the Problems) The present invention provides a key input means for inputting a password for identity verification, a card capable of reading and writing information, and a card reading and writing means for exchanging information. The present invention is directed to a PIN verification method in a card terminal device which includes means and a control device for controlling the operation of these means, inputs a PIN number to confirm the identity, and makes the use of the card an action, In order to solve the problem, information indicating the number of digits of the PIN number is set in the card in advance, and when the card is used, the information indicating the number of digits of the PIN number is read from the card by the card reading and writing means. At the same time, the number of digits of the PIN entered by the key input means is counted, and when the number of digits matches, it is assumed that the PIN pressing operation is completed and a verification operation is started. .

(Function) When using a card at a financial institution, etc., the user inserts the card into a card terminal device and inputs a password. A PIN number with an arbitrary number of digits is used, and information about that number of digits is recorded in advance on the card. When the card is inserted and the key input of the password is performed, the card terminal device reads the number of digits information from the card and counts the number of digits of the key input password. When the read digit number information and the counted digit number information match, the completion of pressing the password is automatically detected and a verification operation begins. Therefore, there is no need for the user to confirm the number of digits, and there is no need to provide the card terminal with a special key for confirming the number of digits, thus solving the problems of the prior art.

(Example) An example of the present invention will be described in detail below with reference to the accompanying drawings.
