Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a personal identification device. In particular, the present invention relates to a device capable of performing personal authentication using a plurality of parameters. Further, the present invention relates to a personal authentication device capable of changing a parameter used according to a situation.

[0002]

2. Description of the Related Art In recent years, devices for checking whether or not an individual is an individual have been widely used. For example, it is extremely important to check whether or not the user is a person in the entrance control of a building or so-called online shopping.

[0003] Many conventional personal authentication devices use data peculiar to the individual to check whether or not the user is an individual. For example, parameters unique to the user, such as fingerprints, voiceprints, and signature data, are registered in advance, and the fingerprints and voiceprints presented by individuals are compared with registered data at the time of authentication. As a result of the comparison, if the identity is recognized, the individual is recognized as the individual.

FIG. 9 is a block diagram showing the configuration of a conventional personal authentication device.

FIG. 9A shows a block diagram of a personal authentication device using voice data. This personal authentication device registers voice data input means 112 and voice data of the user in advance. Storage means 106. The comparison / matching means 100 determines whether or not the individual is the person by comparing and comparing the voice data input by the voice data input means 112 with the voice data in the storage means 106.

FIG. 9 (2) is a block diagram showing the configuration of a personal authentication device using signature data. This personal authentication device registers signature data of a principal in advance with signature data input means 116. Storage means 108. The comparison / matching means 104 compares the signature data input by the signature data input means 116 with the signature data in the storage means 110 to determine whether or not the individual is the person.

[0007] As shown in FIG. 9, the conventional personal authentication device has a separate and dedicated device for each authentication parameter.

[0008]

[0006] Personal authentication using signature data requires a pen or an electronic tablet because the user must perform a signature operation. In personal authentication using voice data, the user only needs to speak into the microphone, so that the burden on the user is small.

On the other hand, it is difficult to use personal authentication by voice data in a place where noise is strong. On the other hand, personal authentication using signature data can be used even in a place with a lot of noise.

[0010] Therefore, it is desirable to change the parameters to be used depending on the circumstances surrounding the personal authentication and the environment in which the personal authentication is performed.

[0011] However, the conventional devices are all 1

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 FIG. 1 is a block diagram showing the configuration of a personal authentication apparatus according to a preferred embodiment of the present invention. As shown in this figure,
The personal authentication device 10 includes a voice input unit 12, a lip shape input unit 14, and a signature data input unit 16.

The feature of the first embodiment is that
The personal authentication is performed by comprehensively judging the above three parameters. Since a plurality of types of parameters are used, it is possible to improve the accuracy of personal authentication as compared with the case where a single parameter is used.

The voice input means 12 inputs personal voice data. The lip shape input means 14 inputs a change in lip shape when the individual utters. The signature data input means 16 inputs the personal signature data.

Further, the voice input means 12, the lip shape input means 14, and the signature data input means 16 are provided with corresponding noise detection means 22, 24, 26, respectively. Can each of the noise detection means 22, 24, and 26 detect noise included in data of each parameter such as voice data input by the connected voice input means 12 and the like and can be used as a parameter for personal authentication? Determine whether or not. When each of the noise detection means 22, 24, and 26 determines that the noise is small and can be used as a parameter for personal authentication, the noise detection means 22, 24, and 26 supply the parameter to the subsequent comparison / matching means 30.

Conversely, each noise detecting means 22, 24, 26
However, if it is determined that the data of the parameter is too noisy to use as a parameter for personal authentication, the parameter is not supplied to the subsequent comparison / matching means 30.

Each of the noise detecting means 22, 24 and 26 has a specific reference value relating to the noise. When the noise signal level becomes higher than the reference value, the noise detecting means 22, 24 and 26 can be used for personal authentication. We judge that it is difficult. If the noise signal level is not higher than the reference value, each of the noise detection means 22, 24, and 26 determines that the parameter can be used for personal authentication.

In practice, it is preferable that an appropriate value is obtained by an experiment or the like. This is because the value that is appropriate as the reference value greatly changes depending on the number of persons performing personal authentication, gender, age, and the like. It is also preferable to provide an external setting means so that a human can appropriately adjust the reference value.

Further, each of the noise detecting means 22, 23, 24
Lamp means 22a, 23a for displaying to the user whether or not the corresponding parameter is subjected to comparison and collation;
24a. Each noise detecting means 22, 23, 24
Turns on the corresponding lamp means 22a, 23a, and 24a when it is determined that the corresponding parameter is available. However, when it is determined that the use is difficult, the corresponding lamp means 22a, 23a, and 24a is turned off. By such an operation, the user can easily know which parameter is currently available. For example, if audio data is available, the corresponding lamp means 22a turns on, indicating that the user only needs to emit audio for personal authentication. Also,
If the signature data is available, the lighting of the corresponding lamp means 22c indicates that the user only needs to sign for personal authentication.

On the other hand, even if a voice is emitted toward the microphone,
If the lamp means 22a does not light, the user can know that the voice data cannot be used as a parameter for personal authentication. As a result, the user can receive his / her personal authentication by using parameters other than the voice data.

As described above, the characteristic feature of the first embodiment is that the available parameters are automatically detected,
That is, only available parameters are to be compared and compared. With such a configuration, it is possible to select an appropriate parameter according to the situation, and it is possible to realize good personal authentication.

The comparison / comparison means 30 includes the noise detection means 22,
The parameters supplied from 24 and 26 are compared and collated with parameters such as the voice data of the person registered in the storage means 20 in advance. As a result, when it is determined that the data is related to the same person, the user outputs an authentication result that the user is the person. Conversely, if it is determined that the data does not belong to the same person, an authentication result indicating that the user is not the person is output. The storage unit 20
Is registered in advance with the registered data of the parameter person such as the voice data described above.

Next, the personal authentication device 10 according to the first embodiment
Will be described based on the flowchart of FIG.

First, in step S2-1, the voice input means 12, the lip shape input means 14, and the signature data input means 16 input corresponding data. The voice input means 12 inputs voice data, the lip shape input means 14 acquires lip movement data, and the signature data input means 16 inputs signature data. In practice, it would be rare for these three types of means to input data simultaneously.
For example, when voice data is input, lips generally move, so lip movement data is also input.

Step S2-1 corresponds to an input step of the present invention.

Next, in step S2-2, the noise detecting means 22, 24, and 26 detect noise in the input data and determine whether the data can be used as a parameter for personal authentication. Here, when it is determined that the data can be used as a parameter for personal authentication, the process proceeds to step S2-3, and is subjected to comparison and collation as described later. Conversely, if it is determined that the parameter cannot be used as a parameter for personal authentication, the process proceeds to step S2-6.

This step S2-2 corresponds to the inspection step of the present invention, in particular, the noise detection step.

In step S2-3, the corresponding lamp means 22a, 22b and 22c are turned on. This allows the user to know the available parameters. Step S2-3 corresponds to an inspection step, particularly, a display step of the present invention.

In step S2-4, a comparison and collation process is performed using the available data. This processing is executed by the comparison and collation means 30 as described above. Step S2-4 corresponds to the comparison and collation step of the present invention.

Next, in step S2-5, the comparison and collation means 30 outputs an authentication result as a result of the comparison and collation.

On the other hand, in step S2-6, the corresponding lamp means 22a, 22b and 22c are turned off.
This allows the user to know parameters that are difficult to use. This step S2-6 also corresponds to the inspection step, particularly the display step of the present invention.

As described above, according to the first embodiment, available parameters are automatically selected.

Hereinafter, a specific example of selecting parameters will be described.

Example 1 When the noise around the place where the personal authentication is performed is intense, a lot of noise is mixed in the voice data. In such a case, the noise detection unit 22 determines that personal authentication based on the voice data is difficult, and turns off the corresponding lamp unit 22a. The user sees the turned-off lamp means 22a and knows that personal authentication using voice data cannot be performed.
Then, the user can try to receive personal authentication based on the lip shape and the signature data.

Example 2 When road construction or the like is performed around a place where personal authentication is performed and the vibration is severe, a lot of noise is mixed in the signature data. In such a case, the noise detection unit 26 determines that personal authentication using the signature data is difficult, and turns off the corresponding lamp unit 26a. The user sees the turned off lamp means 26a and knows that personal authentication using signature data cannot be performed. Then, the user can try to receive personal authentication based on the voice data and the lip shape.

As described above, according to the first embodiment, available parameters are automatically selected, and personal authentication using only these available parameters is automatically executed. Therefore, it is possible to realize a personal authentication device that automatically switches parameters according to various situations and can always obtain a highly reliable authentication result.

In the first embodiment, the noise detecting means 22, 24, and 26 for detecting noise are used. However, means for detecting distortion may be used instead of or in addition to them. This distortion detecting device basically operates in the same manner as the noise detecting means 22, 24, 26 and the like. That is, if the distortion in the data is larger than the reference value,
It is determined that the data cannot be used as a parameter for personal authentication, and the data is not supplied to the comparison and collation means 30.

Second Embodiment In the first embodiment, the apparatus automatically determines parameters to be used, and displays the determination result to the user. However, there is a case where a user wants to select a parameter to be used depending on circumstances of the user. For example, even if the surrounding noise is not strong, if the user has a sore throat, personal authentication using voice data is not desirable. If the hand is injured, it is not preferable to perform personal authentication using signature data.

For this reason, the personal authentication device 40 according to the second embodiment includes a parameter selection switch 32. FIG. 3 is a configuration block diagram of the personal authentication device 40 according to the second embodiment. As shown in FIG. 3, the parameter selection switch 32 is connected to the noise detection unit 22,
24, 26. Then, the user operates the parameter selection switch 32 to
The parameters selected by the user are used as noise detection means 22 and 2.
4, 26.

As shown in FIG. 3, the parameter selection switch 32 has three switches of "voice", "lip", and "signature". Each switch corresponds to each parameter of voice data, lip shape change, and signature data. Each switch has three positions of “ON”, “OFF”, and “AUTO” as shown in FIG.

In the "ON" state, the user can forcibly use the parameter for comparison and collation. In this position, each of the noise detection means 22, 24, and 26 always compares the parameter with the comparison and comparison means 3 regardless of the presence or absence of noise.
Send to 0. As a result, the comparison / matching means 30 always uses the parameter at the time of comparison / matching.

In the "OFF" state, the user can prevent the parameter from being forcibly used for comparison and collation. In this position, each noise detection means 22, 24, 26
Regardless of the presence or absence of noise, the parameters are not always sent to the comparison / matching means 30. As a result, the comparison and collation means 30 always ignores the parameter at the time of comparison and collation.

In the “AUTO”, the personal authentication device 4
The operation of 0 is exactly the same as that of the personal authentication device 10 of the first embodiment. That is, whether or not to use the parameter is automatically determined by the noise detecting means 22, 24, 26 by judging the degree of noise.

Therefore, the individual who is to be authenticated can use the parameter selection switch 32 to select parameters in consideration of not only the surrounding situation at the time of authentication but also his own convenience.

Next, the personal authentication device 40 according to the second embodiment
Will be described with reference to the flowchart of FIG. The operation described here is an operation performed when the user selects a parameter using the parameter selection switch 32. That is, the operation is performed when each switch of the parameter selection switch 32 is in the “ON” or “OFF” position. Note that the operation in the “AUTO” position is as follows.
This is the same as in the first embodiment.

First, in step S4-1, the voice input unit 12, the lip shape input unit 14, and the signature data input unit 16 input corresponding data. The operation in this step is the same as that in step S2-1.

This step S4-1 corresponds to the input step of the present invention.

Next, in step S4-2, the user uses the parameter selection switch 32 to select a parameter to be used for personal authentication. Specifically, the user sets a switch corresponding to a parameter to be used to an “ON” position, and sets a switch corresponding to a parameter not to be used to an “OFF” position.

Step S4-2 corresponds to a selecting step of the present invention.

In step S4-3, a comparison and collation process is performed using the data selected by the user. This processing is executed by the comparison and collation means 30 as described above. Step S4-3 corresponds to a comparison / collation step of the present invention.

Next, in step S4-4, the comparison and collation means 30 outputs an authentication result as a result of the comparison and collation.

A specific example in which the user selects a parameter will be described below.

Example 1 For example, in a place where noise is severe, it is difficult to perform personal authentication using voice data, but personal authentication using signature data can be executed. Therefore, the user selects the signature data as a parameter via the parameter selection switch 32 when performing personal authentication in a place with a lot of noise. Also, when the user has a sore throat and it is difficult to utter, the signature data can be selected.

Example 2 If the user has an injured hand, it is difficult to input the signature data, and the user will select personal authentication by voice data.

As described above, in the present embodiment, the parameters used by the user can be freely selected in consideration of the physical environment of the person to be authenticated in addition to the surrounding environment at the time of personal authentication. It is.

As described above, according to the second embodiment, an individual who can smoothly perform personal authentication under various conditions (including not only surrounding conditions but also the convenience of the user). The authentication device 10 is obtained.

Third Embodiment In the first and second embodiments, various methods for selecting parameters when performing personal authentication using a plurality of types of parameters have been described. In the third embodiment, a mobile phone capable of inputting a plurality of parameters used for personal authentication will be described.

FIG. 5 is an external view of a mobile phone 44 according to the third embodiment. As shown in FIG.
When a conversation is made using the camera 4, a camera 50 is provided near the position of the lips of the user. This camera 50
The change in the shape of the lips of the user during conversation is photographed. In addition,
A microphone 52 for conversation, which is an original function of the mobile phone 44, is also provided near the lips of the user.

The camera 50 corresponds to an image input unit of the present invention, and the microphone 52 corresponds to a voice input unit.

A characteristic feature of the mobile phone 44 of the third embodiment is that a change in the shape of the lips photographed by the camera 50 can be used as a parameter for personal authentication. FIG. 6 is a functional block diagram of the mobile phone 44 relating to the personal authentication.
Is shown in

As shown in this figure, the lip shape photographed by the camera 50 is supplied to the inspection means 60. The audio data input by the microphone 52 is supplied to the inspection means 62. The operation of these inspection means 60 and 62 is exactly the same as that of the inspection means 22 and 24 described above. That is, when the inspection means 60 and 62 determine that the supplied parameters such as the voice data cannot be used for personal authentication due to noise or the like, the inspection means 60 and 62 do not transmit the parameters to the subsequent comparison / matching means 64. Then, only the parameters judged to be usable are transmitted to the comparison and collation means 64. The comparison / comparison unit 64 also performs the same operation as the above-described comparison / comparison unit 30, and outputs an individual authentication result. The authentication result is supplied to the permission unit 66.

When the authentication result is affirmative, that is, when the user is the user, the permission means 66 enables the predetermined function of the mobile phone 44. Function is unavailable. Thus, it is possible to prevent a person other than the person from falsifying or stealing the data of the mobile phone, for example, the telephone directory.

It is also preferable that the permitting means 66 permits so-called electronic commerce. Only when the authentication result is positive, by permitting the connection to the server that performs the electronic commerce, only the principal can perform the electronic commerce.

Note that the predetermined function may be a part of the function of the mobile phone 44 or all functions.

In the present embodiment, the mobile phone 44
The camera 50 is provided at a position where the user can take a picture of the lips of the user when the user is placed at a position where a telephone conversation is performed with respect to the user's head. By providing a camera at such a position, the mobile phone 44 can be fixed to the user's head, and a change in the shape of the lips can be well photographed.

Although the example in which the comparison / matching means 66 performs personal authentication has been described, it is also preferable that the external server performs this personal authentication. In order to be able to adopt such a configuration, the mobile phone 44 is provided with a transmission unit 70. The transmitting means 70 includes the inspection means 6
It has a function of transmitting each parameter passed through 0 and 62 to an external server or the like. With this function, the mobile phone 44 can transmit the voice data and the parameters of the lip shape change to the outside (that is, the server). As a result, personal authentication can be performed based on the parameters sent from the external server.

As described above, a so-called e-commerce server or the like can be used to execute personal authentication externally. There are various forms of electronic commerce. For example, a form is used in which personal authentication is performed at the time of login and only the user can log in. In the electronic commerce of such a form, the mobile phone 44 can easily transmit parameters for personal authentication to the outside, and has an effect that the execution of the electronic commerce is facilitated.

The mobile phone 44 is provided with parameter selection means 68. This parameter selection means 6
The operation of 8 is the same as that of the parameter selection means 32 described above. That is, the user can select a parameter to be used in consideration of not only the surrounding environment but also his own convenience.

Embodiment 4A In Embodiment 3 described above, only one camera 50 is provided, but it is preferable to use two cameras. The change of the shape of the lips can be captured using two cameras rather than one camera.
If you capture them from different directions, you can grasp the three-dimensional movement. Therefore, more accurate personal authentication can be realized.

In this case, the two cameras correspond to the first camera means and the second camera means of the present invention, respectively.

Embodiment 4B In the above-described embodiment 4A, an example in which two cameras are provided has been described. However, it is also preferable that a mirror is used instead of the second camera, and the camera itself is constituted by one. FIG. 7 shows a usage example of the mobile phone 80 adopting such a configuration. As shown in this figure, the camera 50 photographs the lips of the user from a predetermined direction, and the mirror 82 provides the camera 50 with an image when the lips are viewed from different directions. Therefore, with only one camera 50, it is possible to obtain images of the lips viewed from different directions.

As described above, according to Embodiment 4B,
The same effect as in Embodiment 4A can be obtained with only one camera.

In FIG. 7, the mirror 82 is provided on the inner surface of the so-called flip of the mobile phone 80. However, any position can be used as long as images of the lips from different directions can be provided to the camera 50.

The mirror 82 corresponds to the mirror means of the present invention.

Embodiment 4C In the examples described so far, the camera 50 is provided at a position near the lips during conversation in order to photograph the shape of the lips. However, the necessity of having a conversation when performing personal authentication is not so large. In other words, at the time of personal authentication, the mobile phone may be used in a different direction and position from the telephone conversation.

Therefore, the camera 50 may be provided at any position on the portable telephone.

For example, FIG. 8 shows an example of a mobile phone 90 in which the camera 50 is provided near a receiver (speaker) of the mobile phone. When the camera 50 is provided at such a position, it is preferable to position the mobile phone 90 in front of the user's face during personal authentication. At such a position, predetermined voice data and a change in lip shape are transmitted to the mobile phone 90.
Enter it toward.

However, in such a usage, the positional relationship between the camera and the lips tends to fluctuate, and so-called “shake” tends to occur. For this reason, it is preferable to use a means of "camera shake correction" generally used in a video camera or the like.

[0135]

As described above, according to the present invention, personal authentication is performed using a plurality of parameters. Therefore, parameters can be selected according to various situations, and highly accurate personal authentication can be performed.

Further, according to the present invention, since the user can select a parameter, personal authentication can be performed using a parameter that matches the user's convenience.

Further, according to the present invention, it is possible to obtain a parameter used for personal authentication and to provide a communication device that can transmit the parameter to the outside, so that it is possible to smoothly perform identity verification in so-called electronic commerce.

If the communication device itself is provided with a comparison and collation function, personal authentication can be performed by the communication device itself. Furthermore, since a predetermined function of the communication device can be configured to be executable only by the person himself / herself, a communication device that can easily realize confidentiality protection and privacy protection can be obtained.
