Description

  The present invention relates to a fingerprint authentication device, and more particularly to a fingerprint authentication device that divides and authenticates a fingerprint.

  Fingerprint authentication technology has been developed, and fingerprint authentication devices are being installed in various electronic devices. For example, fingerprint authentication is used for authentication at the time of login of a personal computer. In the fingerprint authentication method, for example, the entire fingerprint of one or more fingers of the same person is registered in advance, and the registered fingerprint data is collated with the input fingerprint data. At this time, since the entire fingerprint data is collated, one kind of fingerprint is usually registered for one finger of the same person and authentication is possible.

  However, it is relatively easy to collect a fingerprint, and the fingerprint is collected without the knowledge of the person, and in some cases, forgery can be performed. For this reason, there is a problem that the security is lowered because “spoofing” by a third party can occur due to illegal fingerprint collection. In addition, since the number of fingers that can be authenticated is limited, the number of authentication settings is limited. Therefore, there are problems that one person cannot perform many different authentications, and security is lowered when the same fingerprint is registered for a plurality of authentication targets. Furthermore, since the types that can be input by the fingerprint are limited, it is difficult to use as an input device.

  On the other hand, a technique related to fingerprint authentication is disclosed in Patent Document 1 below. In the technique disclosed in Patent Document 1, first, fingerprint data of one finger is divided into a predetermined number, and the registration order of each divided part is set and registered. At the time of authentication, the inputted fingerprint is recognized, and the number of divisions and registration order of the recognized fingerprint data are inputted. Thus, authentication is performed based on whether the fingerprint data of each divided part based on the number of divisions of the input fingerprint data matches the registration order of each divided part.

JP 2006-331355 A

  However, in the technique disclosed in Patent Document 1, the fingerprint itself is to be authenticated at one time, and the number of divisions and the registration order of each divided portion, which are authentication parameters, need to be input separately. Therefore, the fingerprint data and the number of divisions and the data in the registration order are input separately, and the user may be troublesome to input. In addition, as described above, if fingerprints are collected and registration order data represented by numbers is acquired separately, unauthorized authentication by a third party may be performed, and security still remains. There was a problem that improvement could not be achieved. Further, since registration order data is required in addition to the fingerprint, it is difficult to configure an input device that realizes various inputs only by the fingerprint.

  For this reason, the object of the present invention is to prevent unauthorized authentication by a third party, which is the above-described problem, to improve security, and to enable various inputs using fingerprints, thereby improving user convenience. It is.

A fingerprint authentication device according to an aspect of the present invention is:
Authentication reference data storage means for storing fingerprint data serving as an authentication reference, and order data representing the authentication order of each predetermined divided portion of the fingerprint data;
Fingerprint data input acceptance means for accepting input of divided fingerprint data in a predetermined divided portion of the fingerprint data in the order of input;
Whether or not the divided fingerprint data received by the fingerprint data input receiving means matches the divided portion of the fingerprint data stored in the authentication reference data storage means is matched and stored in the authentication reference data storage means Fingerprint collation means for collating whether or not the divided fingerprint data is input in the order set in the order data;
The structure that is equipped with.

  Since the present invention is configured as described above, it is possible to realize a fingerprint authentication device with high security, easy input, and high user convenience.

  The present invention relates to a fingerprint authentication device, a program, and a fingerprint authentication method for authenticating together divided fingerprint data obtained by dividing fingerprint data into a predetermined number and the input order of each divided fingerprint data.

And the fingerprint authentication device which is one form of the present invention,
Authentication reference data storage means for storing fingerprint data serving as an authentication reference, and order data representing the authentication order of each predetermined divided portion of the fingerprint data;
Fingerprint data input acceptance means for accepting input of divided fingerprint data in a predetermined divided portion of the fingerprint data in the order of input;
The divided fingerprint data received by the fingerprint data input receiving means and the divided portion of the fingerprint data stored in the authentication reference data storage means are collated to be matched and stored in the authentication reference data storage means. Fingerprint collation means for collating whether or not the divided fingerprint data is input in the order set in the order data;
The structure that is equipped with.

  According to the above invention, first, divided fingerprint data, which is each divided portion of the user's fingerprint data, is sequentially input. Then, each input divided fingerprint data is matched with each divided part of the registered fingerprint data, and whether or not the input order of each input divided fingerprint data is matched with the registered order data is verified. If they match, the authentication is successful. Accordingly, since the user moves his / her finger so that the divided parts of the fingerprint data are input in the registered order, the user can input the fingerprint data and the order data at the same time. Therefore, since the divided fingerprint data and the order data are used as authentication data while being easy to input, security can be improved. In particular, the user can remember the data to be input by the movement of the finger, and the convenience can be improved.

  Further, the fingerprint authentication device uses the divided fingerprint data received by the fingerprint data input receiving means as fingerprint data as an authentication reference, and represents data indicating the input order of the divided fingerprint data received by the fingerprint data input receiving means as order data. As an example, a configuration is adopted in which authentication standard data registration means for storing in the authentication standard data storage means is provided.

  As a result, the registration of authentication reference data consisting of divided fingerprint data and order data indicating the input order can also be input by the user by moving the finger, and the fingerprint data and the order data can be input simultaneously. Can do. Therefore, registration is easy, and authentication data registered by finger movement can be learned.

  In the fingerprint authentication device, the fingerprint collating unit collates whether or not a plurality of divided fingerprint data whose input intervals are within a preset time are input in the order set in the order data. Take the configuration. Thereby, the divided fingerprint data inputted at intervals within a preset time can be received as a series of divided fingerprint data inputted in order, and a series of divided fingerprint data inputted for authentication can be discriminated. It becomes easy. Therefore, it is possible to improve the authentication accuracy.

  The fingerprint authentication device includes a fingerprint reading device that reads the divided fingerprint data that is received by the fingerprint data input receiving unit from the fingerprint, and the fingerprint reading device can read at least a part of the fingerprint. It takes the structure of being formed in a size. As a result, the fingerprint reading apparatus can accept input of at least a predetermined divided portion of the fingerprint data, so that authentication as described above is possible. Therefore, the size of the fingerprint sensor or the like can be reduced.

  In addition, the fingerprint authentication apparatus includes a sequence data setting unit that sets the sequence data stored in the authentication reference data storage unit. Further, the fingerprint authentication apparatus adopts a configuration in which the order data stored in the authentication reference data storage means is set so as to include the same divided fingerprint data. As a result, since the order data of the divided fingerprint data can be set in any order as the authentication reference data, many kinds of different authentication standards can be set with a small number of fingers. Therefore, security can be improved.

  The fingerprint authentication apparatus includes an input unit that performs a predetermined input corresponding to a collation result by the fingerprint collation unit to a predetermined input target device. Thereby, a predetermined input can be performed on the input target device according to the collation result. In particular, when authentication reference data is set so that a plurality of types of authentication can be performed, a plurality of types of inputs can be performed for each type of authentication. Therefore, the authentication device can be used as an input device.

Moreover, the program which is the other form of this invention is:
In a computer provided with authentication reference data storage means for storing fingerprint data as an authentication reference and order data representing the authentication order of each predetermined divided portion of the fingerprint data,

To achieve the above.

  Then, the program executes, on the computer, the data representing the input order of the divided fingerprint data received by the fingerprint data input receiving unit as the authentication fingerprint based on the divided fingerprint data received by the fingerprint data input receiving unit. As the data, an authentication standard data registration unit stored in the authentication standard data storage unit is realized.

In addition, the fingerprint authentication method according to another aspect of the present invention is:

Fingerprint collation process for collating whether or not the divided fingerprint data is input in the order in which
It has the configuration of having.

  In the fingerprint authentication method, before the fingerprint data input receiving step, the input of the divided fingerprint data in a predetermined divided portion of the fingerprint data is received as the fingerprint data as an authentication reference, and the data representing the input order of the divided fingerprint data Is adopted as an order data, and an authentication standard data registration step for storing it in the authentication standard data storage means is employed.

  Even the invention of the program and the fingerprint authentication method having the above-described configuration can achieve the above-described object of the present invention because it operates in the same manner as the above-described fingerprint authentication device.

  Hereinafter, specific configurations and operations of the present invention will be described in the embodiments. In the embodiment, the case where the fingerprint authentication device and the operation target device operated by the operator using the authentication result are configured as separate devices is illustrated, but the present invention is limited to such a configuration. Not. The fingerprint authentication device may be configured integrally with the operation target device. Further, the authentication result by the fingerprint authentication device may be used for any operation such as access permission and data input.

<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. 1 and 2 are block diagrams showing the configuration of the fingerprint authentication apparatus. FIG. 3 is a diagram illustrating an example of collation data. 4 to 5 are diagrams illustrating an example of a fingerprint input operation. 6 to 7 are diagrams illustrating the operation of the fingerprint authentication device.

[Constitution]
The fingerprint authentication device in the present embodiment is a device that performs fingerprint authentication in order to determine an operator's access right to the connected operation target device 2. That is, when the fingerprint authentication is successful, an operation permission signal is transmitted to the operation target device 2 and the operation of the operator is permitted.

  As shown in FIG. 1, the fingerprint authentication device 1 includes a fingerprint sensor 11, a registration unit 12, a verification unit 13, a control unit 14, a verification data storage unit 15, and a memory unit 16. ing. The registration unit 12, the collation unit 13, and the control unit 14 are realized by incorporating a fingerprint authentication program into an arithmetic device such as a CPU equipped in the fingerprint authentication device 1. Hereinafter, each configuration will be described in detail.

  The fingerprint sensor 11 (fingerprint reading means) has a function of reading an operator's fingerprint, generating fingerprint data, and passing the fingerprint data to the registration unit 12 and the verification unit 13. For example, as shown in FIG. 4, the fingerprint sensor 11 is formed in a slit shape whose length in the horizontal direction in FIG. 4 is slightly longer than the width of a human finger. Then, when the operator scans the slit side of the fingerprint side of the finger F, the fingerprint sensor 11 can acquire fingerprint data. As will be described later, the fingerprint sensor 11 acquires divided fingerprint data obtained by dividing the operator's fingerprint data into a predetermined number. For example, a part of fingerprint data such as the upper half or lower half of the fingerprint (see FIG. 4), the left and right halves (see FIG. 8), or each of the four divided parts (see FIG. 10) is acquired. If possible. Therefore, the shape of the fingerprint sensor 11 is not limited to the above shape, and the length (the length in the horizontal direction in FIG. 4) is shorter than the width of the finger as shown in other embodiments described later. May be. That is, the fingerprint sensor 11 only needs to be formed in a size that allows at least a partial range of the fingerprint to be read.

  The registration unit 12 (authentication standard data registration unit) registers the fingerprint data input from the operator in the verification data storage unit 15 (authentication standard data storage unit) as authentication standard data to be verified at the time of authentication. It has the function to do. Specifically, the divided fingerprint data, which is a part of the fingerprint data, is received from the fingerprint sensor 11 and registered as collation fingerprint data 51 in the collation data storage unit 15, and the input order of each divided fingerprint data Are registered as collation order data 52 for collation.

  Here, an example of the authentication reference data registered in advance is shown in FIG. First, as shown in FIG. 3A, as the fingerprint data 51, the divided fingerprint data of each finger is stored for each user (see reference numeral 51a). In this example, as shown in FIG. 4, the fingerprints obtained by dividing each finger F of the user into the upper half and the lower half along the node direction are set as divided fingerprint data 51aa and 51ab, respectively. Further, as shown in FIG. 3B, the authentication order of the divided portion of each finger F is stored as order data for each user (see reference numerals 52a and 52b). For example, in the case of the user A indicated by reference numeral 52a, as shown in FIG. 4, data representing the order of “upper half” to “lower half” of the finger F is stored. As a specific input method, for example, as shown in FIGS. 4A and 4B, the operator places the finger F upward from the bottom, that is, above the finger F with respect to the fingerprint sensor 11. Scanning starts and stops once the upper half is scanned. As a result, first, the upper half of the fingerprint data is input. Thereafter, the lower half of the finger F is further scanned to input data of the lower half of the fingerprint. Then, the upper half divided fingerprint data and the lower half divided fingerprint data input in order are distinguished and registered in the fingerprint data 51 (reference numeral 511aa, etc.), and the order data 52a indicating the order is registered. Is done. Therefore, the operator can register the divided fingerprint data and the order data by a series of finger movements.

  FIG. 5 shows a registration example of the divided fingerprint data 51b and the order data 52b of the user B shown in FIGS. 3 (a) and 3 (b). As shown in FIG. 5, in the case of the user B, the fingerprint sensor 11 is scanned from the upper side of the finger F, and is temporarily stopped when the upper half is scanned. Thereafter, the lower half of the finger F is further scanned, and once the lower half is scanned, the finger F is stopped again. Further, after that, the finger F is moved downward to scan the lower half. Then, the divided fingerprint data is input in the order of “upper half”, “lower half”, and “lower half”, and the divided fingerprint data and the order data are registered respectively. In this way, the order data may be set so that the same divided fingerprint data is included in the collation order. In addition, although the operation described above includes an operation to temporarily stop in order to distinguish the divided parts, it is determined that the input of the fingerprint has been completed after an excessively long time, so that such determination is not performed. When the fingerprint data of the divided part is input, it is temporarily stopped for a short time.

  Further, the registration of the fingerprint by the registration unit 12 is not necessarily limited to the above method. For example, first, the fingerprint data of the entire finger F is input, the number of divisions of the fingerprint data, and the data for determining the collation order of the divided parts divided by this are input to the fingerprint authentication apparatus 1 by the operator. By doing so, the fingerprint data 51 and the collation order data 52 described above may be registered. That is, the fingerprint authentication device 1 may include order data setting means for setting the collation order data.

  As shown in FIG. 2, the verification unit 13 includes an input reception unit 31, a fingerprint verification unit 32, a temporary storage unit 33, and an order verification unit 34. The control unit 14 includes a memory control unit 41 and an operation control unit 42. These units are realized by incorporating a fingerprint authentication program into the fingerprint authentication apparatus 1 as described above.

  The input receiving unit 31 (fingerprint data input receiving means) receives the input of the divided fingerprint data input from the fingerprint sensor 11 in the order of input. For example, when fingerprint data is input as shown in FIG. 4, the fingerprint verification unit accepts the divided fingerprint data in the order of (1) the upper half of the finger F and (2) the lower half of the fingerprint. Pass to 32. At this time, the input receiving unit 31 receives the fingerprint data input at every predetermined time interval as divided fingerprint data of each divided part. For example, as described above, the fingerprint sensor 11 is scanned from the upper side of the finger F, and is temporarily stopped when the upper half is scanned. Thereafter, the lower half of the finger F is further scanned to input data of the lower half of the fingerprint. In this way, by interposing a short time during scanning, the “upper half” and “lower half” of the finger F are distinguished, and input is received as a series of divided fingerprint data necessary for one authentication. If there is no input of the divided fingerprint data within a preset time longer than the time of the pause, it is determined that the input of the divided fingerprint data is completed.

  The fingerprint collation unit 32 collates whether or not the divided fingerprint data that has received the input matches the fingerprint data 15 stored in the collation data storage unit 15. That is, it is compared whether the fingerprint data partially matches. Further, when the divided fingerprint data is input from the input receiving unit 31 continuously within a predetermined time, it is also verified as a series of fingerprint data in the same authentication. Then, when the verification result of each divided fingerprint data is passed to the temporary storage unit 33, the temporary storage unit passes the verification result and the input order to the memory control unit 14 of the control unit 14 and temporarily stores them in the memory unit 16. To do. As a result of collation, from which the fingerprint data 51 stored in the collation data storage unit 15 is matched, which division part the input divided fingerprint data is (for example, said upper half or lower half) Information) can be discriminated, and the input order is stored in the memory unit 16 together with the information.

  After that, when fingerprint data is not obtained from the input receiving unit 31 within a predetermined time, the fingerprint collation unit 32 determines that the input of a series of divided fingerprint data in the same authentication is completed and stores it in the memory unit 16. The collation result and the input order are extracted. Then, the order collation unit 34 collates the input order of the input divided fingerprint data with the collation order data 52 stored in advance in the collation data storage unit 15, and the registered authentication reference data Determine whether they match. If they match, the operation control unit 42 is notified of information to that effect. As described above, the fingerprint collation unit 32, the temporary storage unit 33, and the order collation unit 34 perform fingerprint authentication by collating the input divided fingerprint data with the fingerprints of the respective divided parts and their input orders. Functions as a verification means.

  When the operation control unit 42 receives a notification that the authentication is successful, the operation control unit 42 transmits an operation permission signal to the operation target device 2 to permit the operator's access.

[Operation]
Next, the operation of the fingerprint authentication device 1 configured as described above will be described with reference to the flowcharts of FIGS. FIG. 6 shows an operation when registering authentication reference data, and FIG. 7 shows an operation at the time of authentication.

  First, an operation for registering authentication standard data will be described with reference to FIG. 6 (authentication standard data registration process). First, the operator inputs division settings such as how to divide fingerprint data into the fingerprint authentication device 1. For example, it is assumed that a setting “to divide a fingerprint into two parts vertically in parallel with a node” is input. The fingerprint authentication apparatus 1 that has received the data sets the first input divided fingerprint data as half divided fingerprint data in the first vertical direction, and the next input divided fingerprint data as half the second vertical direction. It is set so as to be accepted as divided fingerprint data (step S1).

  Thereafter, the operator scans the finger F with respect to the fingerprint sensor 11 as shown in FIG. At this time, as indicated by an arrow, when scanning is performed so that the finger F is read from the bottom, that is, from the upper side to the lower side of the finger F, (1) divided fingerprint data in the upper half and (2) divided in the lower half Fingerprint data is input in order (step S2). Then, each divided fingerprint data is stored in the collation data storage unit 15, and data representing the order of each divided fingerprint data is also stored (step S3). Thereby, the authentication reference data is registered.

  Next, the operation at the time of fingerprint collation will be described with reference to FIG. First, the operator scans the finger F with respect to the fingerprint sensor 11 as shown in FIG. At this time, as shown by the arrow, when scanning is performed so that the finger F is read from the bottom, that is, from the upper side to the lower side of the finger F, the upper half of the divided fingerprint data is first accepted by the authentication device (step S11, Fingerprint data input process). Then, the fingerprint authentication device 1 collates the input divided fingerprint data, which is the upper half fingerprint data, with the fingerprint data 51 stored in the collation data storage unit 15 (step S12 fingerprint collation step). The collation result (for example, “upper half of finger 1: collation success”) and the input order (for example, “first”) are temporarily stored in the memory unit 16 (step S13).

  Subsequently, the operator further moves the finger F from the bottom to the top within a predetermined time, and inputs the divided fingerprint data of the lower half of the finger F (Yes in step S14). Then, the lower half of the divided fingerprint data is input (step S11, fingerprint data input process), and verification is performed in the same manner as described above (step S12, fingerprint verification process). Then, for example, the collation result (“lower half of finger 1: collation success”) and the input order (for example, “second”) are stored in the memory unit 16 (step S 13). Thereafter, the process is repeated every time the divided fingerprint data is input.

  Then, if the divided fingerprint data is input within the predetermined time (No in step S14), it is determined that the input of the fingerprint data by the operator is completed, and the divided fingerprint data stored in the memory unit 16 is verified. The result and the input order of the divided fingerprint data are read out. Then, it is determined whether or not the input order of the divided fingerprint data successfully authenticated matches the collation order data 52 registered in the collation data storage unit 15 (step S15, fingerprint collation process). For example, as shown in FIG. 4, if the finger F is moved from the bottom to the top, collation is performed in the order of “upper half → lower half”, so that the divided fingerprint data and the order data match and authentication is determined to be successful. The On the other hand, when the finger F is moved from the top to the bottom, the verification fails in the order of “lower half → upper half”. When the authentication is successful (step S16), input of an operation command for the operation target device 2 according to the authentication result, login processing, and the like are performed.

  As described above, according to the above-described fingerprint authentication device, not only the fingerprint data but also the input order of the divided fingerprint data is an authentication parameter. Even if it is illegally used, the authentication order of each divided portion of the fingerprint data is also required, so that impersonation of another person can be effectively suppressed. As a result, security can be enhanced. Accordingly, the operator can learn the input order of each divided fingerprint data by the movement of the finger, so that the convenience can be improved.

  Further, by changing the authentication order of each divided fingerprint data, a plurality of pieces of authentication data can be created with one individual finger (one fingerprint). For example, it is possible to set different settings for e-mail addresses, personal computer account authentication, etc. that require a plurality of individual managements, and to manage them easily.

  In addition, since the divided fingerprint data obtained by dividing the fingerprint data into a plurality of parts is used for authentication, the size of the fingerprint sensor 11 may be configured so that at least one divided fingerprint data can be input. For this reason, the apparatus can be miniaturized and can be easily mounted on a mobile phone, a small notebook computer, or the like.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 8 is a diagram illustrating a state when fingerprint data is input, and FIG. 9 is a diagram illustrating an example of data stored in the collation data storage unit. FIG. 10 is a diagram illustrating an example of fingerprint division, and FIG. 11 is a diagram illustrating a state when fingerprint data is input.

  In the present embodiment, another example of dividing fingerprint data is shown. As shown in FIG. 8, the fingerprint is divided into left and right along the length direction of the finger. In such a case, as shown in FIGS. 8A and 8B, the divided fingerprint data can be input in the order of right → left, left → right.

  In this embodiment, an input character correspondence table indicating input characters corresponding to each collation order as shown in FIG. 9 is stored as the collation order data 52 in the collation data storage unit 15. This table indicates that when the divided fingerprint data is input as shown in “input order”, the characters set for each can be input. That is, the fingerprint authentication device 1 in the present embodiment can make various inputs to the operation target device 2 according to the input order of the divided fingerprint data to be input, and can be used as an input device. Specifically, as shown in FIG. 8A, when the divided fingerprint data is input in the order of “right half” → “left half” of the finger F, the character “E” can be input. As shown in (b), when the divided fingerprint data is input in the order of “left half” → “right half” of the finger F, the character “U” can be input. For example, the operation control unit 42 of the control unit 14 illustrated in FIG. 2 functions as an input unit that inputs characters according to the authentication result to the operation target device 2.

  Moreover, although the case where the fingerprint data was divided into two was illustrated above, the number of divisions is not limited to this. For example, as shown in FIGS. 10A and 10B, it may be divided into 4 divisions, 9 divisions, or another number. In addition to this, collation order data is also registered. For example, as shown in the lower part of FIG. 11A, a case where “1 → 3 → 4 → 2” is registered as collation order data is considered. In this case, the operator operates the fingerprint sensor 11 so that the divided areas of the finger F are in the order of the registered collation order data. That is, as shown by the arrow, it is moved in an inverted U shape. Thereby, the divided fingerprint data of the divided part of each number is sequentially input to the fingerprint sensor 11 and collation is executed as described above, and the authentication is successful. FIG. 11B shows a case where the fingerprint data is divided into four and the collation order data is registered as “4 → 2 → 1 → 3”. In this case, the operator operates the fingerprint sensor 11 so that the divided portions of the finger F are in the order of the registered collation order data. In other words, as shown by the arrow, by moving it in a U-shape, verification is executed and authentication is successful.

  As described above, various combinations of collation order data can be registered by subdividing a fingerprint into four or nine. Therefore, many types of authentication can be set and executed with a small number of fingers. As a result, the fingerprint authentication device 1 can be used as an input device capable of inputting various characters.

  Further, by increasing the number of divisions, the fingerprint area that needs to be input at a time is reduced, so that the fingerprint sensor 11 having a smaller shape can be used. For this reason, the fingerprint authentication device itself can be miniaturized and can be mounted on a small device such as a mobile phone.

  INDUSTRIAL APPLICABILITY The present invention can be used as a fingerprint authentication device that performs login authentication to a personal computer and is mounted on the personal computer, or an input device that enables data input such as characters by moving a finger. Have
