Abstract

PURPOSE:To improve safety by recording a voice signal of the owner of an individual identification card in the card in addition to a secret number, and at the using of the card, comparing the secret number and the voice with the recorded ones. CONSTITUTION:In addition to the latent recording of a secret number in a magnetic stripe 10 of an individual identification card 1, a prescribed owner's voice is recorded in a V-shaped groove-like voice recording track, which has a similar constitution to a record plate, fitted to a magnetic stripe 11 prepared in parallel with the magnetic stripe 10 or the side edge 11 of the card. At the use of the card, the secret number keyed in by the owner and the owner's voice are stored and compared with the data read out from the card 1. Thus, the safeness is improved by double checking.

Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to various transaction processing devices such as automatic teller machines that use a personal authentication card (hereinafter referred to as an ID card), and particularly relates to various transaction processing devices such as automatic teller machines that use a personal authentication card (hereinafter referred to as an ID card). The present invention relates to a personal authentication method for confirming whether a person matches a cardholder.

<Background of the Invention> Conventionally, in this type of personal authentication method, the personal identification number of the individual to whom the card is to be attached is recorded on the magnetic stripe provided on the ID card at the beginning of the transaction, and then recorded on the ID card at the time of the transaction. The system reads the entered PIN and compares it with the PIN entered by the card user to determine if the two match or do not match. However, in the conventional method,
If someone else obtains an Ir) card and obtains the PIN number by some means, someone other than the card holder can easily carry out transactions, so there is a risk that this will be misused for fraudulent transactions. It was extremely expensive.

<Object of the Invention> An object of the present invention is to provide a novel personal authentication method that improves the safety of various automatic transaction systems using ID cards by employing the individual's voice as a verification medium.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention records the voice of the card holder on the ID card in advance, reads this recorded voice and inputs the voice of the card user at the time of transaction. In particular, both voices were compared to see if the card user was the same as the card holder.

According to the present invention, even if the ID card falls into the hands of another person, the voice of that person does not match the recorded voice of the ID card, so there is no risk of fraudulent transactions being completed, improving the security of transactions. can.

Further, by combining the method of the present invention with the conventional authentication method using a personal identification number, excellent effects such as double checking of the authenticity of the card user can be achieved, achieving the purpose of the invention.

<Description of Embodiments> FIG. 1 shows an In card 1 used for implementing the present invention. The illustrated ID card 1 has a magnetic stripe 10 on the card surface for recording a PIN number and various information necessary for transactions (hereinafter referred to as magnetic information), and a magnetic stripe 10 for recording the cardholder's voice (hereinafter referred to as voice information) in an analog manner. An audio recording track 11 for recording is provided in parallel. Figures 2 and 3
Another ID card 1 shown in the figure has a similar magnetic stripe 10 on the card surface, and a groove-shaped audio recording track 11 having the same structure as a record disc on the card side end surface.

FIG. 4 shows the internal mechanism of a transaction processing device corresponding to the ID card of FIG. In the illustrated example, a conveyance mechanism 21 consisting of conveyance rollers 22, 23.24 and a conveyance belt 25 is provided between a pair of parallel running guides 20.20, and
A magnetic head 3 forms a conveyance path 2 for the D card 1 and reads magnetic information from the magnetic stripe 10 of the ID card 1 onto the conveyance path 2, and a magnetic head 3 reads magnetic information from the magnetic stripe 10 of the ID card 1 onto the conveyance path 2, and from the audio recording track 11 of the ID card 1 to the side of the conveyance path 2. A voice reading mechanism 4 for reading voice information is provided in each case. The voice information read by the voice reading mechanism 4 is transmitted to a filter 5 as shown in FIG.
After being converted into a digital signal through an A/D converter 6, the information is taken into an arithmetic processing unit 7 (hereinafter referred to as CPU) together with the magnetic information read by the magnetic head 3, and each piece of information is stored in a memory 70.

Some card users enter their PIN number using the keyboard 9, and a voice input means 8 consisting of a microphone for predetermined voice input.
Enter the following information.

Then, the audio input is performed using the filter 5 and the A/D as described above.
After being converted into a digital signal via the converter 6, it is taken into the CPU'7 together with the key input. In this way, the CPU 7 determines whether or not the key input matches the magnetic information, and further determines whether the voice input matches the voice information. The cardholder is recognized as the same as the cardholder, and the transaction is allowed to proceed.In addition, the audio is determined by checking whether the basic frequency matches, etc.
An appropriate determination method may be adopted.
