Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention does not perform comparison and collation with stored fingerprint data for one fingerprint image input by a user as in the prior art.
The present invention relates to a fingerprint identification apparatus, a fingerprint identification method, and a recording medium on which a fingerprint identification program that reads the above fingerprint images, performs comparison and collation on each of them, and enables more accurate and reliable fingerprint authentication.

2. Description of the Related Art Two systems, a biometrics system and an authentication token system, are used as systems for mechanically authenticating an individual. The biometrics method focuses on individual physical characteristics and performs personal authentication. There is no need to carry an authentication token such as an IC card, so there is no problem of loss, and there is no problem of forgetting a password. Promising as a reliable method. It is easy because it does not require anything, and it is said that it can be spoofed. Voiceprint recognition using personal physical characteristics,
Each method of iris recognition and fingerprint recognition can be improved. A voiceprint represents a voice in a complicated striped pattern by a frequency analyzer, and can be used for authentication. The iris is a disc-like thin film having a pupil in the center between the cornea and the lens of the eyeball, and can identify an individual by the state of the sphincter, the radiation muscle, the pigment, and the like. Fingerprints are wrinkles of the skin on the abdominal surface of the finger end and have a bow-like, spiral-like, or hoof-like shape, and are used as the basis for personal identification because they vary from person to person and do not change throughout life. Fingerprinting was established in the late 19th century by British geneticist Francis Galton as a method of identifying individuals.

[0003] As an example of a fingerprint identification device so far, FIG.
The one using an optical sensor as shown in FIG. 9 and the one using a semiconductor sensor of a capacitance type as shown in FIG. 20 are known. The optical discriminator 9 includes a light source 91 that emits visible light or infrared light to a finger placed on the surface of the glass 90,
Optical sensor 92 for receiving light reflected by glass 90
And a lens 93 placed on a focal plane between the optical sensor 92 and the glass 90 surface. As the light source 91, a light emitting diode is often used. A charge-coupled device, an image scanner, or the like is often used for the optical sensor 92. The fingerprint appearing on the surface of the glass 90 is focused by the lens 93 and picked up by the optical sensor 92 as a bright and dark striped image. The capacitance discriminator 94 obtains a striped pattern image from the distribution of the capacitance between the pixel array 95 on which the finger is placed and the striped pattern (fingerprint) 96 of the finger, and has recently been used as a pointing device. Some models have a semiconductor fingerprint sensor attached to the center of the mouse.

The image signal of the fingerprint is converted into fingerprint data of a digital signal by an A / D converter, and is subjected to well-known fingerprint identification processing such as a minutiae method and a pattern matching method. The fingerprint identification device is used for personal logistics such as logon to computers using the above-mentioned mouse, credit authentication of Internet shopping, etc., door lock and unlocking of entrances and garages, and key systems for automobiles. In addition, shared use by unspecified large numbers of people, such as automatic teller machines at banks, membership authentication systems at amusement stores, and personal authentication at retail stores, can be raised.

[0005]

According to such a conventional method, there is no need to carry an authentication token, so there is no problem of loss, and there is no problem of forgetting a password, but a copied fingerprint is used. As a result, an erroneous determination that allows impersonation may be made.

On the other hand, since a finger is placed on the surface of the glass 90 or on the pixel array 95 for identification, dust and the like adhere to the surface of the finger and finger oil along with the dirt, thereby lowering the recognition rate. There is. In addition, there is a case where the finger is not recognized well due to a problem such as rough skin or dry skin on the finger side. However, in the case of using fingerprint identification for the shared use terminal, it is expected that if recognition is not performed well, a long line will be formed and the user will be unpopular.

Accordingly, a first object of the present invention is to improve security by making it impossible to impersonate with only one copied fingerprint. Further, in the password method, the order in which the key switches on which alphanumeric characters and the like are displayed is determined, but the concept of the order is introduced in this way.

A second object of the present invention is to make it possible to more reliably perform fingerprint identification without waiting for the user even in a situation where the recognition rate is low.

[0008]

The above object is achieved by a single fingerprint image reading sensor, a storage device for storing fingerprint data for comparison, and a fingerprint image at one or more predetermined time intervals. This is achieved by a fingerprint identification device comprising a control device for reading and comparing each image with the fingerprint data based on an identification algorithm. That is, one fingerprint image reading sensor reads a fingerprint image once or two or more times at a predetermined time interval, reads fingerprint data in a storage device for each image, and compares them based on an identification algorithm. I did it. The identification algorithm may use a minutiae method, a pattern matching method, or the like that is well known in the related art. Further, a sensor that has been conventionally used, such as an optical sensor or a capacitance sensor, may be used as the sensor.

In this case, the first fingerprint image is read by one fingerprint image reading sensor, the next fingerprint image is read at a predetermined time interval, and these fingerprint images are compared with the fingerprint data at a predetermined timing. If all matches are found, the identity can be verified. Alternatively, in the case where the fingerprint image is read three or more times, it is possible to set that it is sufficient to match two or more times. The predetermined timing refers to a case where the fingerprint image is compared with the fingerprint data each time the fingerprint image is read once, a case where the fingerprint image is compared with the fingerprint data after all the times are completed, or a case where these are mixed. In the case where all the read fingerprint images must match the fingerprint data, the fingerprint data is compared with the fingerprint data each time the fingerprint image is read once. Can be set to be regarded as not being able to verify the identity. In addition, it is also possible to set so as to allow duplicate reading of the fingerprint image. Whenever the identity of the user can be confirmed by reading the fingerprint image each time, a lamp display or a display may be displayed to that effect to prompt the user to authenticate the next finger. Thus, the first problem has been achieved.

[0010] Next, when a match is not made due to low recognition accuracy or the like even though a correct fingerprint image is input, a fingerprint of a finger different from the first finger is used, for example, at a predetermined time interval. The second fingerprint image reading may be performed and compared with the fingerprint data. Therefore, it can be set so that it can be identified by changing the finger any number of times until a match is made. However, unlike the conventional case, at least two identification operations are possible. Thus, the second problem has been achieved.

Note that two or more fingers may be placed on the glass surface, all of which may be read by one fingerprint image reading sensor, and handled as separate fingerprints by subsequent image processing. After that, it is subjected to various kinds of processing for identity verification as described above. Even in this case, it is necessary to read the fingerprint image once or at least two or more predetermined time intervals.

Further, in the present invention, it is determined whether or not the reading order of the fingerprint images is correct after the identification. When a fingerprint image reading sensor reads a fingerprint image once or two or more times at a predetermined time interval, the order of the fingers to be used is specified. If the order is not correct, it is considered that the identity could not be confirmed. It can be set to be considered. For example, if three types of copied fingerprints are used for three readings, all three will surely match,
Only the order of the authentication can be determined by applying the same order. In this case, if the order is incorrect even once, it may be determined that the identity cannot be confirmed.

Further, the present invention provides two or more independent fingerprint image reading sensors, a storage device for storing fingerprint data for comparison, and a fingerprint image read for each fingerprint image reading sensor based on an identification algorithm. This is achieved by a fingerprint identification device comprising a control device for comparison with data. That is, the fingerprint image is read by each of the two or more independent fingerprint image reading sensors, and the fingerprint data in the storage device is read for each of the images and compared based on the identification algorithm. As the identification algorithm, a minutiae method, a pattern matching method, or the like well known in the related art may be used. Further, a sensor that has been conventionally used, such as an optical sensor or a capacitance sensor, may be used as the sensor.

In this case, it is possible to use two or more independent fingerprint image reading sensors at the same time, or to set them so as to link them with a time lag, so that faster processing can be performed, and more complicated and accurate identity verification can be performed. Can be performed. When two or more fingerprint readings are simultaneously processed by one fingerprint image reading sensor as described above, there is no need to perform image processing so that the fingerprints can be handled as separate fingerprints. Only one fingerprint needs to be targeted for reading. When linking with the above-mentioned time difference, there is a choice as many as the number of fingerprint image reading sensors for the same one finger, and if the order of the fingers to be used is specified, it is set so that fingerprint images can be read repeatedly. Thus, the complexity can be increased by the number of times. In addition, every time the identity can be confirmed by reading the fingerprint image each time, the user may be prompted to authenticate the next finger by turning on a lamp to indicate the identity or displaying it on the display. . Thus, the first problem has been achieved.

Further, since two or more independent fingerprint image reading sensors are used, for example, three fingers are used for three sensors, and when two of these are authenticated, the identity is confirmed. It can be set to be considered.
In this case, it is convenient if the authentication is not performed by one sensor but is performed by another sensor. Thus, the second problem has been achieved.

Further, in the present invention, it is determined whether or not two or more fingerprint images are read by the reading sensor at the same time within a predetermined time. That is, a finger is exposed to two or more fingerprint image reading sensors within a certain period of time, which is generally described as reading two or more fingerprint images at the same time. Regardless of whether or not the fingerprint is read, an error occurs unless a plurality of sensors read the fingerprint at the same time. To cope with this method, the user must determine in advance which finger and which finger pair to use, and must use it promptly for authentication. Therefore, more complicated or more accurate personal authentication is possible.

Further, according to the present invention, after the identification, it is determined whether or not the reading order of the fingerprint images is correct.
In this case, the order of the fingers to be used for reading each fingerprint image by the reading sensor is defined, and if the order is not the order, it may be set so that it is considered that the identity cannot be confirmed. I can do it. Alternatively, the order may be defined in cooperation with two or more fingerprint image reading sensors. Therefore, more complex personal authentication can be performed by employing the concept of the order. Note that as long as the order is met, it can be set so as not to specify which finger is read by which fingerprint image reading sensor. It is also possible to set a combination of the above-described two or more fingerprint images read by the reading sensor at the same time within a predetermined period of time. For example, complicated settings such as the finger and the finger at the same time, the finger at the sensor, the finger at the next sensor, and the same at the same time can be made.

The present invention relates to a system for reading and comparing fingerprint images at one or more predetermined time intervals with one fingerprint image reading sensor, or two or more independent fingerprint image reading sensors. In each of the methods of reading and comparing fingerprint images, it is determined whether fingerprint images obtained by prompting two or more different persons to input belong to the same authentication group. In this case, a process of registering fingerprint images of two or more different persons in advance and registering as fingerprint data of different persons is performed. The fingerprint data registration unit stores the fingerprint image read from the fingerprint image reading sensor as it is or after analyzing it, together with other personal data such as a name in a storage device. At this time, members belonging to the group may be recorded on the same record, or may be related to each other even if they are different records.

Therefore, the present invention can also be used with an unspecified number of people using a shared terminal such as an automatic teller machine at a bank, a membership authentication system at an amusement store, an individual authentication at a retail store, and the like. However, rather than using it with family members in personal areas such as entrance and garage door locks and unlocks, car key systems, etc. It can be said that a group sharing a certain interest, such as a lover or a friend, is suitable for use. In order to prompt two or more different persons to input, it may be determined whether or not fingerprint images of two or more different persons simultaneously identified within a predetermined time belong to the same authentication group. . Good link play of the concerned parties is required.

The present invention also relates to an apparatus for reading and comparing fingerprint images at one or more predetermined time intervals with one fingerprint image reading sensor, or two or more independent fingerprint image reading sensors. A password input section is provided for each of which reads and compares a fingerprint image, and the control device determines whether or not the password is correct based on an input signal from the password input section, and determines the result of the fingerprint. This was added to the discrimination. user·
As an interface, for example, a numeric keypad is provided so that the identification is not regarded as the identification unless both the identification by the password and the identification by the fingerprint are satisfied.

Therefore, according to the present invention, merely by stealing the password, or by simply using the copied fingerprint,
Impersonation is impossible, and the probability of making an incorrect determination is reduced. In the worst case, only the identification using the numeric keypad is sufficient, so that even if the fingerprint reading, which is a simpler identification method for the user, does not work well, the password input using the numeric keypad is added.

The recording medium on which the program is recorded is a CD.
-ROM, hard disk, flexible disk, R
The concept includes OM, RAM, memory card, paper tape, punch card, and the like. In addition to a recording medium on which a program is recorded in a state that can be directly executed by a computer, for example, a recording medium on which a program which can be executed by being installed from a CD-ROM to another recording medium such as a hard disk, or data is stored. Encoding,
It also includes a recording medium on which an encrypted or compressed program is recorded. The reason for including the RAM is that the program received via the network may be loaded on the RAM.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the design can be arbitrarily changed without departing from the spirit of the present invention.

FIGS. 1 to 6 show a first embodiment of the present invention. This means that two fingerprints, such as a right index finger and a left middle finger, are identified and identification is performed. The cover plate 10 is attached to the case 1 whose upper part is open.
Is attached. An opening 11 is provided at the center of the cover plate 10, and a glass plate 12 is inserted into the opening 11. An LED lamp 21 that emits light toward the opening 11 is provided inside the case 1, and an area CCD 2 is provided at the bottom of the case 1.
0 is interposed.

Next, the fingerprint identification circuit 3
To 0, a fingerprint data storage unit 31 for storing a required number of fingerprint data per individual and a control unit 3 are connected. The area CCD 2 and the LED lamp 21 are connected to the control unit 3. The control unit 3 has a role of performing ON / OFF of these devices and transferring a fingerprint image read by the area CCD 2 to the fingerprint identification unit 30. The control unit 30 prompts the user to input two types of fingerprints in this embodiment. The fingerprint identification unit 30 compares the two received fingerprint images with the fingerprint data stored in the fingerprint data storage unit 31 to determine whether or not the user is the principal.

Next, FIG. 5 shows a hardware configuration when the fingerprint identification device of FIG. 1 is realized by using the CPU 4.
The CPU 4 is provided with a memory (RAM). Also, a hard disk (HDD) 40 as a storage device, a keyboard / mouse 42 as an input device, a display 43 as a display device, an input / output board 44 as an interface of the area CCD 2 and the LED lamp 21, a CD-ROM
The drive 41 is connected. The hard disk 4
In 0, an operating system OS5, a fingerprint identification program 50, and a fingerprint database 7 are stored. These programs are installed from the CD-ROM 45 via the CD-ROM drive 41.

The fingerprint identification program 50 prompts the user through the display 43 to input two types of fingerprints.
In this case, there is no particular restriction on the input order. The first read is stored as the first fingerprint in the buffer 1 (step S1). Next, the read fingerprint is stored in the buffer 2 as a second fingerprint (step S2).
Then, the first fingerprint is compared with the fingerprint data stored in the fingerprint database 7 (step S3). If there is a match, the process proceeds to the next step S4. If not, the identity is not confirmed. And tell NG.
If a match is found, the second fingerprint is compared with the fingerprint data stored in the fingerprint database 7 (step S4), and if a match is found, the identity is confirmed and OK is notified. If there is no match, tell NG. If no match is found, re-entry may be prompted. Also, the opening 11 is set to have a sufficient size for placing two fingers, and at the same time, the fingerprints of two fingers are read, image-analyzed, divided into two, and sequentially set for comparison and collation. May be.

FIG. 7 shows a second embodiment of the present invention.
The fingerprint identification device that can be used is that of the first embodiment described above, but the processing form is slightly different. That is, it is checked whether or not the reading order of the two fingerprints matches. Note that the step numbers used in the following description are the numbers following the first embodiment, but are not independent of the processing performed after the processing of the first embodiment, but are independent processing.

The first fingerprint is read and stored in the buffer 1 (step S5), and the second fingerprint is read and stored in the buffer 2 (step S6). First, the fingerprint stored in the buffer 1 and the fingerprint database are stored. The stored fingerprint data is compared and collated (step S7), and if a match is found, the fingerprint stored in the buffer 2 is compared with the fingerprint data stored in the fingerprint database (step S7).
8) If they match, it is further determined whether or not the reading order of the first fingerprint and the second fingerprint matches, and if they match, it is confirmed for the first time that the user is the principal. As a result, there are two types of patterns for inputting a correct fingerprint set, which is more difficult.

FIGS. 8 to 12 show a third embodiment of the present invention. This means that three fingerprints, such as the index finger, the middle finger, and the ring finger of the right hand, are input at the same time to identify and perform identity verification. A cover plate 60 is attached to the case 6 whose upper part is open. This lid plate 60
Are provided with three openings 61 to 63 at the center thereof, and prisms 64 to 66 are fitted in each of them through a damper 67. LED lamps 25 to 27 which emit light toward the prisms 64 to 66 are respectively provided inside the case 6.
Are provided, and LED lamps 25 to 2 are provided at the bottom of the case 6.
7, area CCDs 22 to 24 are provided.
A lens 20 (only one is shown in the front) is interposed between them.

Next, regarding the fingerprint identification circuit, the fingerprint identification unit 3
To 0, a fingerprint data storage unit 31 for storing a required number of fingerprint data per individual and a control unit 3 are connected. The control unit 3 includes area CCDs 22 to 24 and LED lamps 25 to
27 are connected. The control unit 3 controls these devices O
In addition to performing N / OFF, it has a role of transferring a fingerprint image read by each of the area CCDs 22 to 24 to the fingerprint identification unit 30. The control unit 30 prompts the user to input three types of fingerprints in this embodiment. The fingerprint identification unit 30 compares the received three fingerprint images with the fingerprint data stored in the fingerprint data storage unit 31 to determine whether or not the user is the principal.

Next, FIG. 5 shows a hardware configuration when the fingerprint identification device of FIG. 11 is realized by using the CPU 4.
The CPU 4 is provided with a memory (RAM). Also, a hard disk (HDD) 40 as a storage device, a keyboard / mouse 42 as an input device, a display 43 as a display device, area CCDs 22 to 24 and an LED lamp 2
An input / output board 44 which is an interface of 5 to 27;
A CD-ROM drive 41 is connected. The hard disk 40 has an operating system OS5,
The fingerprint identification program 51 and the fingerprint database 7 are stored. These programs are installed from the CD-ROM 46 via the CD-ROM drive 41.

Although a flowchart showing the fingerprint authentication procedure is not shown, it substantially conforms to the first embodiment. That is, the first
Is read and stored in the buffer 1, the second fingerprint is read and stored in the buffer 2, the third fingerprint is read and stored in the buffer 3, and the fingerprint and the fingerprint database stored in the buffer 1 are first stored. The stored fingerprint data is compared and collated. If there is a match, the fingerprint stored in the buffer 2 is compared and collated with the fingerprint data stored in the fingerprint database. The stored fingerprint and the fingerprint data stored in the fingerprint database are compared and collated, and if they match, the user is confirmed as the first person.

It is also possible to adopt a method in which a time lag is provided and one by one is placed on each of the three prisms 64 to 66 without placing a finger at the same time. In this case, either of the right and left fingers may be used as long as registration is performed, and it is also possible to set reading three or more times. It is possible to arbitrarily set a pattern of using the above or placing two fingers almost simultaneously. Since each area CCD 22 to 24 reads one fingerprint at the same time, one area CCD is superior in recognition power as compared with the case where two or more fingerprints are read. By incorporating the concept of combination and order, more reliable personal authentication can be performed.

FIG. 13 shows a fourth embodiment of the present invention. This processing method can be used in the form of the opening of the present invention, and determines whether or not fingerprint reading has been simultaneously performed within a predetermined time at the same time. The first fingerprint is read and stored in the buffer 1 (step S10). At this time, the timer is started and the first fingerprint is read.
The time from the reading of the first fingerprint to the reading of the second fingerprint is measured (step S11), the second fingerprint is stored in the reading buffer 2 (step S12), and the second fingerprint following the reading of the first fingerprint is first measured. It is determined whether the time until the reading of the fingerprint is performed within a predetermined time (step S1).
3) If the second fingerprint is not read within a predetermined time, NG is determined. However, if it is performed within the time, the fingerprint stored in the buffer 1 is compared with the fingerprint data stored in the fingerprint database (step S14), and if they match, the fingerprint is stored in the buffer 2. The fingerprint and the fingerprint data stored in the fingerprint database are compared and collated (step S15), and if they match, the user is confirmed for the first time here.

Even if a person who has several copies of a fingerprint tries to be authenticated, he or she must know which combination, and if it is too slow, it will be NG. In addition, even if the user himself / herself wishes for authentication, if the user is still dying, it is determined to be NG.

FIG. 14 shows a fifth embodiment of the present invention. This processing method can be used in the form of the opening of the present invention, and is almost similar to the fourth embodiment. Further, this embodiment is characterized in that it is determined whether fingerprint images obtained by prompting two different persons to input belong to the same authentication group. The fingerprint of the first person is read and stored in the buffer 1 (step S16),
At this time, a timer is started to measure the time from the reading of the first person's fingerprint to the subsequent reading of the second person's fingerprint (step S17), and then the second person's fingerprint is read and stored in the buffer 2. (Step S18), it is determined whether the time from the reading of the fingerprint of the first person to the reading of the fingerprint of the second person is performed within a predetermined time (Step S1).
9) If it is performed within the time, the fingerprint stored in the buffer 1 is compared with the fingerprint data stored in the fingerprint database (step S20), and if they match, the fingerprint is stored in the buffer 2. The fingerprint and the fingerprint data stored in the fingerprint database are compared and collated (step S21), and if they match, it is checked whether the first person and about two persons belong to the same group (step S21). S22). If any one of these steps does not match, it is determined that two persons could not be identified or the group could not be confirmed, and is determined to be NG.

In this case, a process of registering fingerprint images of two different persons in advance and registering them as fingerprint data of different persons is performed. The fingerprint data registration unit (not shown) stores the fingerprint image read from the fingerprint image reading sensor as it is or after analyzing it along with other personal data such as a name in a storage device. At this time, members belonging to the group may be recorded on the same record, or may be related to each other even if they are different records. FIG. 15 shows an example of such a database. In the fingerprint database 7, personal data 71, 72 and the like are recorded.
1, 72 belong to the same group and are surrounded by a group 70.

FIG. 16 shows a sixth embodiment of the present invention. The fingerprint identification device of this embodiment is similar to that of the first embodiment described above, and further comprises a numeric keypad 8 provided on the right side of the opening. It has features. A password authentication unit using a numeric keypad (not shown) is provided, and attempts to perform both password authentication combining numbers and personal authentication using a fingerprint.

Even if the password is known to another person, the user cannot be identified without the fingerprint. Conversely, even if you have a copy of your fingerprint, you will not be able to identify yourself without knowing your password. Furthermore, since it is necessary to know the order in which the fingerprints are placed, it is very difficult to identify the person. In the case of using a group, it is also possible to set such that a person authenticated by a fingerprint and a person authenticated by a password are separated.

FIGS. 17 and 18 show a seventh embodiment of the present invention. The fingerprint identification device of this embodiment is similar to that of the above-described second embodiment, and is further characterized in that a numeric keypad 8 is provided on the right side of the opening. A password authentication unit using a numeric keypad (not shown) is provided to perform both password authentication combining numbers and personal authentication using fingerprints.

The user is prompted to input a predetermined number of fingerprints, and if all of them match (step S23), a password input is requested from the switch group of the numeric keypad 8 (step S24).
If entered, the password is verified (step S2
5) The user is confirmed as the first person after the password matches. Here, since the fingerprint identification device is similar to that of the second embodiment, the difficulty level of identity verification is extremely high for a person other than the person.

[0041]

As described above, according to the present invention, a fingerprint image reading sensor reads a fingerprint image once or two or more times at a predetermined time interval, and prints fingerprint data in a storage device for each image. The comparison is made based on the read identification algorithm. In addition, a fingerprint image is read by each of two or more independent fingerprint image reading sensors, and fingerprint data in a storage device is read from each image and compared based on an identification algorithm.

As a result, it was impossible to impersonate with only one copied fingerprint, and security was improved. A fingerprint authentication that incorporates the concept of ordering has enabled more reliable fingerprint authentication. Even in situations where the recognition rate is low, fingerprint identification can be performed more reliably without having to wait for the user.

[0002] Two methods, a biometrics method and an authentication token method, are used as methods for mechanically authenticating an individual. The biometrics method focuses on individual physical characteristics and performs personal authentication. There is no need to carry an authentication token such as an IC card, so there is no problem of loss, and there is no problem of forgetting a password. Promising as a reliable method. It is simple because it does not require anything and can not be spoofed. Each of the methods of voiceprint recognition, iris recognition, and fingerprint recognition can be used as those utilizing individual physical characteristics. A voiceprint represents a voice in a complicated striped pattern by a frequency analyzer, and can be used for authentication. The iris is a disc-like thin film having a pupil in the center between the cornea and the lens of the eyeball, and can identify an individual by the state of the sphincter, the radiation muscle, the pigment, and the like. Fingerprints are wrinkles of the skin on the abdominal surface of the finger end and have a bow-like, spiral-like, or hoof-like shape, and are used as the basis for personal identification because they vary from person to person and do not change throughout life. Fingerprinting was established in the late 19th century by British geneticist Francis Galton as a method of identifying individuals.
