Abstract

PURPOSE:To prevent completely an illegal use by using a magnetic storage part as a data updating memory corresponding to a change with time lapse of a personal feature parameter encoded by a CPU in an IC card with a magnetic stripe. CONSTITUTION:A feature parameter subjected to a change with time lapse, such as a finger-print, voice, face, etc. of a card owner 4 is written and stored in a magnetic storage part 1. When a card 3 is inserted into a terminal machine 5, the terminal machine 5 requests the owner 4 to present his fingerprint, voice, face, etc., reads them by a feature reading part 51, and transmits them to an IC circuit 2 of the card 3. A data read from the owner 4 is compared with a data stored in the magnetic storage part 1 by a matching circuit 203, and when both of them are matched with a high accuracy, an operating part 55 of the terminal machine 5 is operated. The latest feature parameter of the owner 4 is encoded by an encoding circuit 204, and thereafter, written in the magnetic storage part 1 of the card 3 through a magnetic storage reading and writing part 53.

Description

[Detailed description of the invention] The present invention relates to an ID card holder verification method.

Conventionally, in ID cards with a magnetic stripe, the data stored on the magnetic stripe can be easily read using a magnetic peer, a personal computer, etc., so the data is read and modified as data. be able to.

Therefore, with a conventional ID card on which only a four-digit PIN code or the like is written, there is a risk that the data may be tampered with and used fraudulently.

In addition, in an IC card equipped with an IC module,
If characteristic parameters such as fingerprints, voice, and face are stored in the IC circuit as personal information and this data is subjected to verification processing, since the memory of the IC circuit is FROM,
It was difficult to update data according to changes in feature parameters.

The present invention provides an ID card holder verification method that eliminates the above-mentioned conventional drawbacks, prevents unauthorized use due to data falsification, and allows data to be updated in accordance with changes in individual characteristic parameters. The purpose is to

The present invention is a method for verifying the holder of an IC card with a magnetic stripe, in which the holder's data is stored as a magnetic memory 7, and when the card is inserted into a terminal, the holder's data is read by the terminal. At the same time, the terminal device reads the holder's data from the card's magnetic storage section and sends the data to the IC circuit, and in the IC circuit, the terminal device reads the data collected from the holder and the magnetic memory. When it is determined that the person is the same person, a signal to that effect is sent to the terminal,
In addition, if there is a difference between the data read from the owner by the terminal and the data read from the magnetic storage unit, the terminal will read and collect data from the owner only if the difference is within the range that can be determined to be the same person. This is an ID card holder verification method characterized by writing the received data into a magnetic storage section.

Next, one embodiment of the present invention will be described.

As shown in FIG. 1, an IC card 6 with a magnetic stripe is used, which is provided with a magnetic storage section 1 and an IC circuit 2.

In place of the card holder's PIN code, the magnetic storage unit 1 stores characteristic parameters that change over time, such as the card holder's fingerprint, voice, face, etc.
Write it down and memorize it.

When verifying the card holder, as shown in FIG. 2, when the holder 4 inserts the card 3 into the terminal 5, the terminal
requires the bearer 4 to present characteristics such as fingerprints, voice, face, etc. When the holder 4 provides these characteristics, the terminal device 5 reads them with the characteristic reading section 51, parameterizes the data with the sampling section 52, and then transmits the data to the IC circuit 2 of the card 3 using a normal transmission code. do.

In addition, the terminal device 5 reads the holder's 4 (change over time) Z parameter stored in the magnetic storage section 1 of the card holder 4 using the magnetic storage reading/writing section 53, and transmits the unprocessed Z parameter of the card holder 4 from the transmission section 54. It is transmitted to the IC circuit 2.

The magnetic storage data transmitted from the transmission section 54 is sent to the input/output section 2.
1 to the decoding circuit 201 in the CPU 20, each card is decoded using a 3% random number code generated from the random number code generation circuit 202, and the matching circuit 2
03, and in the matching circuit 203, the human output section 22
Performs matching processing with personal characteristic parameters transmitted in normal code from . As a result of the matching process, if the data read from the holder 4 and the data stored in the magnetic storage unit 1 are matched with the same accuracy or with high accuracy, the matching circuit 206 sends a message indicating that the holder is the holder himself/herself. A signal is sent to the operation section 55 of the terminal 5 to start the subsequent operation of the terminal 5, and at the same time, the data in the IC circuit 2 is released to the owner 4.

The latest characteristic parameters of the holder 4 transmitted from the terminal 5 to the input/output unit 22 when sending a signal indicating that the holder is the holder himself/herself are sent to the terminal 5 according to the random number code generated from the random number code generation circuit 202. The encoder circuit 204 encodes the data, sends this data and a write instruction signal to the terminal 5, and writes the data into the magnetic memory section 1 of the card 6 from the magnetic memory read/write section 56.

If it is determined that the owner is the owner in this way, the data in the magnetic storage unit 1 is updated to the latest personal verification code of the owner 4.

FIG. 3 is a flowchart of the method of the present invention.

The present invention is a method in which personal characteristic parameters are encoded by the CPU in an IC card with a magnetic stripe, and the magnetic storage unit is used as a memory for updating data corresponding to changes over time in the IC card. Since it verifies the identity of the user, unauthorized use can be completely prevented. Unlike conventional systems that use only a personal identification number, the personal identification number cannot be read out from the magnetic storage section and used fraudulently.

In the method of the present invention, characteristic parameters such as fingerprints, voice, face, etc. are read from the holder and are matched with data in the magnetic storage unit, so an unauthorized user cannot provide the characteristic parameters of the holder. It cannot be used illegally. Furthermore, even if an attempt is made to read the owner's data from the magnetic storage unit and change it to the unauthorized user's data, the data cannot be updated unless the matching process determines that the user is the same person. It can also be prevented from being used.

If it is determined that the person is the same person through the matching process, the holder's data in the magnetic storage section will be updated to the latest data read at that time, so future matching of the holder will be even more reliable. Become.

Furthermore, since the magnetic storage section is used as an external storage memory of the IC card, there is no need to incorporate another EEFROM or the like into the IC circuit, and the verification system becomes inexpensive.

Furthermore, there is no need for the holder to remember the PIN number, and there is no need for the holder to forget the PIN number and be unable to verify it. This reduces unnecessary operations on the card terminal and eliminates malfunctions.

As described above, the present invention provides a method for effectively verifying the owner and updating data, and has great practical effects.
