The present invention relates to a card verification device with functions.

(B) Conventional technology In general, this type of card verification device uses a card reader to read specific verification data such as a PIN number registered on the card, and check whether the PIN number entered by the person at this time matches. The suitability of the person is determined by determining whether or not the person is eligible.

However, with such verification means, the person in question must remember the password, and in order to increase the confidentiality of the password, the number of digits must be further increased, which increases the burden on the user. Furthermore, when a plurality of cards are shared and handled by multiple users, it is difficult to maintain the confidentiality of the PIN number, resulting in a problem of poor reliability and security.

(c) Problems to be solved by the invention This invention was made by focusing on these conventional problems. The purpose of the present invention is to provide a card verification device with a voice recognition function that can perform verification.

(d) Means for Solving Problems This invention is a card verification device that verifies and verifies registered data based on a card reader reading verification data that captures the voice characteristics of the person registered on the card. hand,
a voice input unit for inputting voice characteristics of the registered person; a voice recognition unit that captures and identifies the voice characteristics input to the voice input unit; and a voice verification unit identified by the voice recognition unit. The present invention is a card verification device with a voice recognition function, which includes an identity verification determination section that determines whether or not the card user is the card user based on data and card verification data read by the card reader.

(e) Effect of the invention According to this invention, when verifying the identity of a person, the card verification data recorded on the card is read by a card reader,
And by inputting the person's voice into the voice input section,
The identity verification determination unit determines whether or not the card user is the actual card user based on the card verification data and the voice verification data that captures the characteristics of the voice.

(F) Effects of the invention In this way, since the verification is performed by voice, the trouble of entering the PIN each time is saved, and the user can quickly perform verification operations, especially when remembering personal data such as the PIN. Since there is no need to keep it in place, the burden on the user can be reduced.

In addition, since verification is performed using the unique voiceprint of each individual, the identification of personal data is accurate and highly confidential, making it suitable for sharing cards that are commonly used by multiple people. , reliability and security are definitely improved.

(g) Examples An embodiment of the present invention will be described in detail below based on the drawings.

FIG. 1 shows a control circuit block diagram of a card verification device with a voice recognition function used in a security system for an opening/closing gate. It is constructed by combining both input systems 11 and 12.

The above-mentioned card input system 11 includes a card 13 for identifying the person.
and a card reader 14 for reading card verification data recorded on this card 13. The card verification data read here is transmitted to a control device 15 and a verification determination device 16, and the control device 15 reads the card verification data. 13 to determine the validity of the card to be verified, and a verification determination device 16 determines whether or not the registered word recorded on the card matches the corresponding voice verification data.

In this case, while the above-mentioned registered words are magnetically recorded in advance on the card 13 so as to be magnetically readable by the card reader 14,
The registered words are written on the front or back side of the card 13 so as to be visible, so that the person who is to be verified at the time of verification can easily input the registered words by voice.

The voice input system 12 also includes a microphone 17 for voice inputting registered words and a voice extraction device 18 for extracting voice characteristics unique to the person. It is converted into an electrical signal and guided to the audio extraction device 18, where audio features due to changes in the electrical signal are extracted and sent to the verification determination device 16,
This comparison/determination device 16 determines whether the registered word input from the card input system 11 described above matches the registered word input from the voice input system 12, and if they match, the switching device 19 is turned ON. It is provided so that it can be output to open and close an opening/closing gate (not shown).

This person's voice verification data captures and confirms the unique voice characteristics of each person, which ensures accurate and highly confidential identification of personal data. It is also suitable when people use it commonly.

In addition, as shown in Figure 2, the registered data for determining the validity of the card itself must specify at least one of the following: purpose of use, card rank, number of card users, name of registrant, etc. Please register and confirm this.

Further, as shown in FIG. 3, as the voice data of registered words to be registered in the card, voice data 1 to NcLn are sequentially set for each registrant to be verified, and for each of these voice data, (1) Pre-processing of input speech, such as wavelength decomposition of frequencies and vowel segmentation recognition, (2) Phonological identification using fuzzy control, etc., which captures the characteristics of consonants from the relationship between wavelength and time, and (3) Identification. Register and manage the three elements of word recognition, which identifies registered words from the phoneme strings that have been created, and use this voice data and
Compare and judge input audio data.

When a card verification device with a voice recognition function configured as described above is used in a security system for an opening/closing gate, the person who is to be verified at the time of verification now holds the card 13 in his hand and reads the card verification data into the card reader 14. Furthermore, when the registered words written on the card 13 are inputted into the microphone 17 by voice, both data are input to the verification determination device 16, and this verification determination device 16 verifies the verification data on the card side and the audio side. If the card user is verified by comparing the data with the card user, a proper signal is output to the switching device 19 to open the gate.

On the other hand, if the verification results do not match or the validity of the card is not recognized by the control device 15, the switching device 1
9 to maintain the closed state of the gate.

As mentioned above, since verification is performed by voice, it is possible to eliminate the trouble of entering a personal identification number each time, and to quickly perform verification operations for the person in question. In particular, since there is no need to remember personal data such as a password, the burden on the user can be reduced.

In addition, since verification is performed using the unique voiceprint of each individual, the identification of personal data is accurate and highly confidential, making it suitable for sharing cards that are shared by multiple people. As a result, reliability and security are definitely improved.

In the correspondence between this invention and the configuration of the above-mentioned embodiment, the audio input section of this invention corresponds to the microphone 17 of the embodiment, and similarly below, the audio identification section corresponds to the audio extraction device 18, Although the person verification determination unit corresponds to the verification determination device 16, the present invention is not limited to the configuration of the above-described embodiment.
