[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a configuration of a personal authentication system according to the present embodiment. This system includes a personal authentication device 11 and an IC card 12 as a portable storage medium. The personal authentication device 11 can display, for example, the finger 2
A one-dimensional pattern (projection signal) of the entire finger 2 due to the difference in the contact area between the finger 2 and the linear electrode array 1
A pattern input unit 13 as a feature input unit for inputting Vraw (i), and a BPF which is pre-processing for registration and collation described later.
The control unit 14 includes a control unit 14 for performing (band-pass filter) processing, authentication processing for registration and collation, and a read / write unit 15 as communication means for communicating with the IC card 12.

The host machine 16 controls, for example, the opening and closing of doors of important facilities and the sounding of an alarm buzzer in response to a control signal from the control unit 14. The host machine 1
The control target 6 differs depending on the security system to which the present system is applied.

The pattern input section 13 is configured, for example, as shown in FIG. That is, reference numeral 1 denotes a linear electrode array, which is formed of n (plural) linear electrodes 3 long in the direction orthogonal to the longitudinal direction of the finger 2 to be verified along the length of the finger 2. And are arranged at predetermined intervals.
The interval between the linear electrodes 3 is, for example, about 1/10 mm. The number of the linear electrodes 3, that is, the length in the longitudinal direction of the finger 2 of the linear electrode array 1 is usually a length that completely includes the second joint from the tip of the finger 2.

A finger 2 to be collated on the linear electrode array 1 is pressed in a direction orthogonal to the electrode arrangement direction. At this time, the resistance value of the surface of the finger 2 between the adjacent linear electrodes 3 is changed in the length direction of the finger 2 by switching and driving the analog switch 4 as switching means connected to each linear electrode 3. Read sequentially.

When the finger 2 is pressed against the n linear electrodes 3, the resistance value between the linear electrodes 3 changes according to the contact area of the finger 2 contacting between the adjacent linear electrodes 3. The resistance value between the i-th linear electrodes 3 at this time is R (i). As shown in FIG. 2, a reference resistor 5 (resistance Rref) and a constant voltage power source 6 (voltage Vo) are connected between two adjacent linear electrodes 3 via an analog switch 4. At this time, the potential difference Vraw (i) between both ends of the reference resistor 5 is given by the following equation (1).

[0018]

(Equation 1)

By sequentially switching the analog switch 4, the potential difference Vraw (i) is sequentially read in the length direction of the finger 2, and is converted into a digital signal by the A / D converter 8 via the sample and hold circuit 7. Timing pulse generator 9
Generates a signal for controlling the switching of the analog switch 4 and the sampling timing of the sample and hold circuit 7. The signal is, for example, as shown in FIG. The analog switch 4 is switched at the falling part of the signal, and the potential difference Vraw (i) is held by the sample and hold circuit 7 at the rising part.

The signal Vraw (i) thus obtained is
For example, as shown in FIG. Vraw (i) has a large value in a portion where the contact area between the finger 2 and the linear electrode 3 is large, and the contact area is small in the side wrinkles in the first joint portion and the second joint portion of the finger 2. , The signal Vraw (i) has a small value. Therefore, Vraw (i) has a steep dip in that portion. Hereinafter, this signal Vraw (i) is referred to as a raw projection signal (feature information).

The IC card 12 is configured, for example, as shown in FIG. That is, a control element (for example, CPU) 21 as a control unit, a non-volatile data memory 22 whose storage content is erasable, a working memory 23,
It comprises a program memory 24 and a contact section 25 for obtaining electrical contact with the read / write section 15. Of these, the portion within the broken line (control element 2
1, the data memory 22, the working memory 23, and the program memory 24) are configured by one (or a plurality of) IC chips and are embedded in the IC card body.

The data memory 22 is used for storing various data, and is composed of, for example, an EEPROM. In this example, the data memory 22 stores a projection signal (characteristic information for collation) of the finger of each person to be authenticated, and the like.

The working memory 23 is a memory for temporarily storing processing data when the control element 21 performs processing, and is composed of, for example, a RAM. The program memory 24 is formed of, for example, a mask ROM, and controls the control element 21 such as a comparison and collation process described later.
And the like.

Next, the flow of processing in the above configuration will be described. The processing is roughly classified into two types, “registration” and “collation”. First, the registration process will be described.

The registration process is performed by the personal authentication device 11 and the IC
There are two on the card 12 side. First, the flow of the registration process on the personal authentication device 11 side will be described with reference to the flowchart shown in FIG.

First, in step S1, the raw projection signal Vraw (i) as shown in FIG.
Take in. Next, in step S2, the BPF, which is pre-processing, is performed on the projection signal Vraw (i) captured in step S1.
(Band pass filter) processing is performed, and this is set as dictionary information (that is, characteristic information for comparison) Vd (i). Next, in step S3, the pre-processed dictionary information Vd (i)
Is transmitted to the IC card 12 by the read / write unit 15.

By performing the BPF processing in step S2, noise can be suppressed by emphasizing the dip generated in the projection signal at the wrinkle positions of the first and second joints of the finger 2, so that individual noise can be suppressed. The authentication ability can be improved.

Next, the flow of the registration process on the IC card 12 side will be described with reference to the flowchart shown in FIG. First, in step S4, the dictionary information Vd (i) sent from the read / write unit 15 of the personal authentication device 11 is received. Next, in step S5, the dictionary information Vd (i) received in step S4 is stored (registered) in the data memory 22.

The reason why the BPF process is performed on the personal authentication device 11 side in the registration process is that the amount of calculation required for the process is large. Regardless of the BPF processing, the filter processing is realized by a product-sum operation in a digital processing system. This process is too heavy for the current control element of the IC card.

In the above example, the number of times of registration processing for one IC card is not limited. However, by limiting this, a more secure personal authentication system can be realized. That is, for one IC card, step S
By making the process of storing the dictionary information in the data memory 5 only once, for example, it is possible to prevent unauthorized rewriting of the dictionary information.

Further, by prohibiting the reading of the contents of the data memory stored in step S5 to the outside of the IC card, it is possible to prevent the dictionary information from being stolen by a third party, and more secure personal authentication. The system can be realized.

Next, the verification process will be described. The matching process is also performed on the personal authentication device 11 side and the IC card 12 side.
There is one. First, the flow of the matching process on the personal authentication device 11 side will be described with reference to the flowchart shown in FIG.

First, in step S6, the raw projection signal Vraw (i) as shown in FIG.
Take in. Next, in step S7, the projection signal Vraw (i) fetched in step S6 is subjected to BPF processing, which is pre-processing, to obtain a projection signal V (i). Next, in step S 8, the pre-processed projection signal V (i) is transmitted to the IC card 12 by the read / write unit 15. Next, in step S9, the read / write unit 15 receives the determination result transmitted from the IC card 12.

After the above collation processing is completed, the control unit 14
Sends the determination result of the person / other to the host machine 16. The host machine 16 performs processing according to the result of the determination, for example, releasing the door when the person is determined to be the person, and sounding an alarm buzzer when the person is determined to be another person. These processes differ depending on the security system to which the present system is applied.

Next, the flow of the collation processing on the IC card 12 side will be described with reference to the flowchart shown in FIG. First, in step S10, the projection signal V (i) sent from the read / write unit 15 of the personal authentication device 11 is received. Next, in step S11, the projection signal V (i) received in step S10 is compared with the dictionary information Vd (i) stored in the data memory 22.

This comparison is realized by calculating the difference E according to the following procedure. First, the projection signal V (i) received in step S10 and the dictionary information Vd (i) read from the data memory 22 are aligned using the following equations (2) and (3). In this case, the sum of the square errors of Vd (i) and V (i + m) obtained by shifting V (i) by m over a certain range is defined as S (m).

[0037]

(Equation 2)

[0038]

(Equation 3)

The value S (m) thus obtained is V (i + m) and V (i + m)
This is a parameter indicating the degree of coincidence with d (i). The smaller the value of S (m), the more coincident. The alignment is
When m is changed within a certain range, M when the value of S (m) becomes the smallest is called a positional deviation amount, and it is assumed that the position is adjusted at this M. Next, the difference E is calculated using the following Expressions 4 and 5.

[0040]

(Equation 4)

[0041]

(Equation 5)

E in the above equations (4) and (5) represents a square error between the aligned characteristic information V (i + M) and the characteristic information (dictionary information) Vd (i) to be collated. The sum obtained over a certain range is normalized by the sum of squares of the feature information Vd (i) to be verified in the same range. E represents the degree of difference between the aligned feature information V (i + M) and the compared feature information Vd (i). The larger the value of E, the greater the difference between the two pieces of feature information. Is larger, and a smaller value indicates that the two feature information items are more similar.

Next, at step S12, the obtained E
Is compared with a predetermined threshold value TH, and [E ≦ T
If H], it is determined that the person to be authenticated is the person himself, and the process proceeds to step S13, where the result of the determination is transmitted to the personal authentication device 11, and the process ends. If it is not [E ≦ TH], it is determined that the person to be authenticated is another person, and step S14 is performed.
To send the determination result to the personal authentication device 11,
The process ends.

In the above-described embodiment, the process of comparing the comparison result E in step S12 with the threshold value TH is performed in the IC card 12, but the comparison process is performed on the personal authentication device 11 side. It can also be configured. That is, instead of transmitting the determination result, the IC card 12 transmits the collation result E to the personal authentication device 11, and the personal authentication device 11 compares the collation result E of step S12 with the threshold TH.
And performs a comparison process with.

Equations 2 to 5 used in the collation processing performed on the IC card 12 are also product-sum operations.
This processing is considerably lighter than the BPF processing performed on one side.
In addition, since the multiplications in these processes are all square calculations,
By storing a square table in the data memory 22 in advance and subtracting the value of the table without performing multiplication, all multiplications can be omitted. In this process,
The control element 21 in the IC card 12 can be sufficiently executed.

In the above-described embodiment, the resistance between the adjacent linear electrodes of the linear electrode array due to the contact of the finger of the person to be authenticated along the arrangement direction of the linear electrode array is used as the pattern input section. The case where the method of inputting the characteristic information of the finger from the value distribution has been described, but the present invention is not limited to this. For example, the image information of the finger of the person to be authenticated is optically captured, and The same applies to the case where an optical system is used in which the feature information of the finger is input by adding the captured image information of the finger in a direction orthogonal to the longitudinal direction of the finger.

[0047]

As described above in detail, according to the present invention, comparison and comparison between physical characteristic information to be verified of a person to be verified and physical characteristic information to be verified are performed in a portable storage medium. In addition, the physical characteristic information to be verified is not read out of the portable storage medium. Therefore, there is little danger of the third party stealing the physical characteristic information to be verified and the verification algorithm, and the security is excellent.
