[0014]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram of an electronic approval system using personal identification according to the first embodiment of this invention.

An electronic approval system using personal identification according to the first embodiment of the present invention comprises a host device 100 and a terminal device 200 connected by a LAN 300.
In FIG. 1, the terminal devices 200 are displayed as one set, but a plurality of terminal devices 200 may be connected to the host device 100 via the LAN 300.

The host device 100 includes an input / output unit 110 for inputting and outputting information to and from an external device such as a terminal device, and a control unit 120 for performing various processes in a predetermined procedure based on the input information and outputting the result to the outside. Storage means 130; retinal matching means 121 for matching input retinal information with retinal information stored in storage means 130; and fingerprint matching means for matching input fingerprint information to fingerprint information stored in storage means 130. 122, a sentence selection unit 125 for selecting a sentence from the sentences stored in the storage unit 130, and the voiceprint information based on the voice information obtained by reading the selected sentence by an individual.
Voiceprint collation means 12 for collating with voiceprint information stored in 30
3, a voice collating unit 124 for collating the voice content with the selected sentence and further determining a security keyword, and a security unit 126 for activating a crime prevention operation according to the determination of the voice collating unit 124.

The host device 100 checks the personal information and recognizes the security keyword based on the information input from the corresponding individual at the terminal device 200, and sends a message to the terminal device 200 to advance the electronic approval process. And send a warning message. In this way, the personal information is stored in the storage means 130 on the host side in order to centrally manage the personal information.

The terminal device 200 has a CPU and is in charge of input / output, collects retinal information, fingerprint information, voice information, etc., transmits information to the host device 100, and receives information from the host device 100. Terminal body 210, retinal recognition device 221 for inputting retinal information used for "retinal recognition function with life reaction detection" used for authentication, and fingerprint recognition device for inputting fingerprint used for fingerprint recognition used for approval 2
22, a microphone 223 for inputting a voice used for the final confirmation of the approval and the security function, and a display 230 used for outputting a message for proceeding with each step of the electronic approval and a warning message.

In the present invention, four types of personal identification and security functions (retinal recognition, fingerprint recognition, voiceprint recognition and voice recognition) are used in the personal identification used in the electronic approval system.・ Using retinal recognition,
Recognizing that the individual is the subject, (2) at the time of approval: using fingerprint recognition and recognizing the approval of the individual, (3) at the time of final confirmation of the approval: using voiceprint recognition and voice recognition In addition, since operation by anyone other than the individual is disabled, approval by involvement of the individual other than the individual can be reliably prevented. Therefore, it can also be used for electronic approval of confidential information in government and the like. Also, (4) crime prevention: By using a "security function based on crime prevention keyword recognition (hereinafter sometimes referred to as a crime prevention function)" using voice recognition, the involvement of individuals other than the individual concerned can be prevented.

Since the electronic approval system is a combination of the above (1) to (4), the security function of the electronic approval system is strengthened to make it impossible for anyone other than the individual concerned to participate. Can be reliably realized.

The above (1) to (4) will be described in further detail. (1) "Retina recognition function with life reaction detection" is used for personal verification and input at the time of authentication. In this way, by confirming a life reaction due to expansion and contraction of the pupil at the time of retinal recognition by the retinal recognition device 221, authentication when the person is killed becomes impossible, and involvement of individuals other than the individual concerned can be prevented. (2) Fingerprint recognition is used for personal verification and input at the time of approval. Since the fingerprint collation by the fingerprint collation function 122 confirms that the person is sitting in front of the terminal device 200, it is possible to surely recognize that the person has been approved with his or her will. (3) The personal verification and input of the final confirmation of all approvals employs a "personal survival determination function using sentence voice input" using voiceprint recognition and voice recognition. This is because when the individual inputs the sentence selected by the sentence selection means 125 and displayed on the display 230 of the terminal device 200 through the microphone 223 in order to make final approval, the host device 1
The voiceprint recognition means 123 and the voice recognition means 124 confirm that the voice input is performed by the individual, and can more reliably recognize that the approval has been made with the intention of the individual. For the text to be adopted, use a current affair such as a newspaper or a text that is likely to be inflected, and change it on a weekly or monthly basis. Digital voice input is detected by increasing recognition accuracy (sampling rate), and input by voice synthesis is disabled. In addition, the "survival judgment function of individual by sentence voice input" makes it impossible to input the voice of the individual recorded on a tape or the like or the input by voice synthesis sampled (digitalized). (4) In order to prevent the approval of the individual at the time of intimidation using a firearm, a knife, etc. in all the processes (1) to (3) above, a "security function based on security keyword recognition" using voice recognition is adopted. Have been. This is a function of notifying an administrator and finally invalidating the approval when it is confirmed by voice recognition that the security keyword has been input by the microphone. For example, if the security keyword is set to "test, test", the individual can be input in a normal manner at the time of microphone operation confirmation before the final confirmation in (3), so that security measures can be taken. A plurality of crime prevention keywords can be designated to enable selection according to the situation, and the microphone can be always inputted so that the opportunity for the person to input the crime prevention keyword is expanded. Even if the crime prevention function means 126 of the host device 100 is activated by receiving the crime prevention keyword, a normal completion message is displayed on the display 230 of the terminal device 200 after the completion of all the steps, and the same operation as that at the time of normal approval is performed. In such a case, it is difficult to realize that the security function means 126 has been activated. The purpose of this crime prevention function is to (a) detect a crime, (b) protect the life of the individual from a threatened person, and (c) detect and prevent involvement of the individual other than the individual.

Next, the operation of the electronic approval system using personal identification according to the first embodiment of the present invention will be described with reference to the drawings. The electronic approval is performed in the order of authentication → authorization → final confirmation of approval. FIG. 2 is a flowchart showing each step at the time of authentication, FIG. 3 is a flowchart showing each step at the time of approval, and FIG. It is a flowchart showing each step at the time of final confirmation.

At the time of authentication, when the authentication is started as shown in FIG. 2 (S101), the display 2 of the terminal device 200 is displayed.
According to the display of 30, the corresponding individual is the retinal recognition device 221.
And the retinal collation means 121 of the host device 100 collates the inputted retinal information with the personal information of the storage means 130 (S102), and when it is confirmed that the retina is the pertinent individual (S102Y). It is checked whether there is a life reaction (S103), and if there is a life reaction (S103).
Y) The authentication proceeds to the next approval (S104), and the authentication ends (S106). The case where the subject is not the retina of the individual (S102N) and the case where there is no life reaction (S103)
N), the authentication is determined to have failed (S105), and the authentication is terminated (S106).

At the time of approval, when approval is started as shown in FIG. 3 (S201), the terminal device 200
The corresponding person inputs fingerprint information from the fingerprint recognition device 222 according to the display on the display 230 of the host device 1.
The fingerprint collation means 122 of 00 collates the inputted fingerprint information with the personal information of the storage means 130 (S202), and when it is confirmed that the fingerprint is that of the individual concerned (S202Y), the approval is successful and the final approval of the next approval is made. Wait for confirmation (S
203), end the approval (S05). If the fingerprint is not the individual's fingerprint (N in S202), the approval is not accepted and the approval is not accepted (S204), and the approval ends (S205).

At the time of the final confirmation of the approval, as shown in FIG. 4, when the approval of all the approval confirmation items is completed, the final confirmation of the approval is started (S301). A final approval sentence is selected from the sentences stored in the terminal device 200 by a predetermined procedure, transmitted to the terminal device 200, and displayed on the display 230 of the terminal device 200 (S301). Next, the individual reads the sentence displayed toward the microphone 223, and in the host device 100, first, based on the voice information input from the terminal device 200, the voiceprint matching unit 123 checks the sentence against the personal information in the storage unit 130. (S303), if it is confirmed that the voiceprint is the voiceprint of the individual (S303Y), subsequently, the voice collating means 124 collates with the final approval text selected by the text selecting means 125 (S304). If it is confirmed that the sentence is a final approval sentence (S304Y), a final approval success message is transmitted to the terminal device 200 and the display 230 is displayed.
(S305). Next, the security means 126 checks whether or not the security operation is in operation (S306). If the security operation is not in operation (S306N), the electronic approval approved at the time of approval is determined as the final confirmation of approval has been successful. After completing all (S307), final confirmation of approval is completed (S310). If the security operation is in operation (S306
Y) determines that the final confirmation of the approval has failed, invalidates all the electronic approvals (S309), and ends the final confirmation of the approval (S310). When it is not the voiceprint of the individual (S30)
3N), when the voice is not the sentence for final approval (S30)
4N), and notifies the administrator of the unauthorized use (S30).
8) Assuming that the final confirmation of the approval has failed, all the electronic approvals are invalidated (S309), and the final confirmation of the approval is terminated (S310).

FIG. 5 is a flowchart showing each step of crime prevention. The crime prevention is performed in a state of always waiting for a voice input from the authentication to the final confirmation of the approval. When the security function is started (S401), the microphone 223 and the voice collating unit 124 enter a standby state (S402), and the terminal device 2
The voice input from the microphone 223 of the “00” is sent to the host device 100, and is stored in the storage unit 13 by the voice verification unit 124.
The security keyword is checked against a pre-registered security keyword stored in the storage device 0 (S40).
3). When the voice is a security keyword (S403)
Y), a notification is sent to the administrator (S404), a predetermined crime prevention operation is activated (S405), and the process returns to step S402 to wait for a voice input. If the voice is not the crime prevention keyword (S403N), it is checked whether the security function has ended (S406). If not, the process returns to step S402 and waits for a voice input. In the case of termination (S406Y), the security function is terminated (S407).

In the above description, the security function is incorporated. However, a high security function can be obtained as a system and method excluding the security function.

In the first embodiment of the present invention, the host device 100 and the terminal device 200 have been described as being connected by a LAN. However, the terminal device 200 can be incorporated in the host device 100. is there.
