Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of an individual collation determination system using a medium according to the present invention, wherein 1 is an image reading unit, 2 is an attribute information input unit, 3 is an image data conversion unit, and 4 is attribute information collation. Section, 5 is an attribute information data file, 6 and 6 'are feature matching sections, 7 is a feature data reading section, 8 is three-dimensional shape data, 9 is a matching determination output section,
Reference numeral 11 denotes a feature information extraction unit, and reference numeral 12 denotes a feature data conversion unit.

Referring to FIG. 1A, an image reading section 1 is a scanner for reading an image recorded on a medium, for example, a card. If it is an image, it is converted to density gradation, and if it is a full color image, it is converted to hue and saturation gradation or R (red), G (green), and B (blue) density gradations It is converted and recorded. The image data conversion unit 3 converts the gradation information of the image data read by the image reading unit 1 into height information, that is, three-dimensional shape data. The attribute information input unit 2 is, for example, a card reader for reading an information recording unit of a card or an electronic key, a key recognition device for recognizing an electronic key of a prescribed shape, a key such as a key input or a touch key for inputting a number or a symbol. It is an input device or the like for performing input of attribute information such as reading input of recording information such as a type including a personal identification code, reading input of a key shape, input of a personal identification number or a symbol, and a format check thereof. Here, the attribute information is, for example, information such as the type and content of a card or a key, a personal identification number or a symbol, and the format is, for example, the shape of a card or a key.
The information includes a size, a recording area of predetermined information (attribute information, a stereoscopic image, and the like), a recording form, and the like.

The attribute information matching section 4 checks whether or not the input attribute information is included in the registered attribute data of the attribute information data file 5. Attribute information data file 5
Is a file in which attribute data registered in advance for comparison by the attribute information matching unit 4 is stored as registered attribute data. The feature collating unit 6 converts the 3
The dimensional shape data is to be collated and determined with the registered feature data in the attribute information data file 5, and the feature data is, for example, ears, mouths, eyes, eyebrows, nose, chin, etc. of the face, and the position, shape, height Etc. is data of information. The feature data reading unit 7 reads registered feature data of the three-dimensional shape data file 8 corresponding to the attribute information matched and matched by the attribute information matching unit 4. The three-dimensional shape data file 8 is a file that stores, as registered feature data, three-dimensional shape data registered in advance for the purpose of collation determination by the feature collation unit 6. The collation judgment output unit 9 is provided with the attribute information collating unit 4
And information on the result of the collation determination by the feature collation unit 6. As for the output information, if the result of the collation determination is a match, the process proceeds to the next process according to the use of the card, the electronic key, or the like.

In the above configuration, the image data is converted into the three-dimensional shape data and the collation is performed. However, FIG. 1B shows an example in which the collation is performed by the image data. In FIG. 1B, a feature information extracting unit 11 extracts feature information from the image data of the image reading unit 1 that has read the recorded image, and a feature matching unit 6 ′ has a feature extracting unit that extracts features from the image data. This is for collating information. Therefore, a feature data conversion unit 12 for converting the registered feature data read by the feature data reading unit 7 into data corresponding to image data is provided between the feature data reading unit 7 and the feature matching unit 6 '.

FIG. 2 is a diagram for explaining an example of a processing flow by the individual collation determination system using the medium according to the present invention. For example, if the input medium is a bank card, a bank code, a branch code, an account number, and an identification number (personal identification number) are used as attribute information in a predetermined recording area predetermined according to a standard. In the recording area, a sculpture image of the face of the holder is recorded as a three-dimensional image. Correspondingly, the terminal of the individual collation determination system has a function of reading attribute information and a three-dimensional image, and a function of inputting an identification number by touch keys. In the individual collation determination system using such a medium, first, as shown in FIG.
The input medium is read and scanned, and the input medium is checked based on a predetermined format as a bank cash card (step S11), the attribute information is read (step S12), and the predetermined recording is performed. It is checked whether or not there is attribute information data in the area (step S13). If there is no attribute information data, an abnormality of the input medium is determined (step S14), and if there is attribute information data, the input number of the identification number from the touch key is continuously determined (step S15). It is determined whether or not the identification number in the attribute information recorded on the input medium matches the identification number input from the touch key (step S16). If the identification numbers do not match, it is determined that the input medium is abnormal (step S16).
14) If they match, the stereoscopic image data stored in the memory is read (step S17). Subsequently, the image recorded on the input medium is read (step S18), and the similarity with the stereoscopic image data is calculated (step S19). It is checked whether or not the calculated similarity is equal to or more than the reference value (step S2).
0) If the similarity is not equal to or more than the reference value, it is determined that the input medium is abnormal (step S14). If the similarity is equal to or more than the reference value, it is determined that the input medium is normal (step S21). By judging that the input medium is normal, the original use of the bank cash card such as cash withdrawal, transfer, balance inquiry, and the like becomes possible.

As described above, in the individual collation judging system using the medium according to the present invention, not only the password but also the image obtained by converting the height of the stereoscopic image data into a gradation is read and collated, and the normality of the input medium is determined. Since the determination of the abnormal condition is performed, it is possible to confirm whether or not the owner of the input medium is a legitimate owner by using the image recorded on the input medium, and to prevent the input medium from being misused as a stolen or found item. In this case, in practice, unless the owner of the input medium and the image recorded on the input medium are visually checked, it is impossible to confirm that the owner is a holder, and therefore, an unattended terminal is required. The problem remains that if the response is made by using only the information, it cannot be prevented from being stolen or misused as a found item. However, when the stereoscopic image data of the face of the holder is converted into an image, it is difficult to reproduce this feature as the stereoscopic image data, so that it can be prevented from being used as falsification or forgery. In the case of image collation, the identification number can be omitted if the attribute information can be associated with the stereoscopic image data even if the identification number is removed from the attribute information.

FIG. 3 is a diagram showing an example of the configuration of an attribute information data file and a three-dimensional shape data file. FIG. 3A shows an example of the configuration of attribute data of a bank card, and FIG.

Attribute data for each attribute data.
Data will be present. Figure 3 shows the latter attribute data.
When applied to the data of (D), individual information can be managed by the unique data added to the 3D data. In other words, when used for management of employee entry / exit, it is possible to identify the entry / exit person from the unique data of the 3D data that matches the stereoscopic image among the input 3D data read from the attribute data.

FIG. 4 is a diagram showing another configuration example of the attribute information data file and the three-dimensional shape data file. FIG.
In the above, the institution number is the number of a financial institution such as a bank or a shinkin bank, and has a pointer of a head address of a group of branch / office numbers under each institution number.
The branch / office number is the number of the branch or office of each financial institution, and has a pointer from the branch / office number to the head address of the group of account numbers. The account number is a number of a deposit account or the like registered in each branch or office of each financial institution, and each account number has a pointer of an ID number address. The ID number is a personal identification number (identification number) registered by the holder of each account.
It has three-dimensional image data whose dimensions have been measured. Of course, as described above, since the ID number and the stereoscopic image data are duplicated as information unique to the holder, the ID number may be omitted and only the stereoscopic image data may be provided for each account number.

FIG. 5 is a diagram showing an embodiment of an information recording medium in which a recording image is added to identification information according to the present invention, and FIG. 6 is a diagram showing an example of a three-dimensional image forming unit. 2 shows an example of a recording card for an image based on the image.

Are displayed in such a manner that they can be seen from information on printed characters or embossed characters that indicate "."

An information recording medium according to the present invention in which a recording image is added to the identification information has image recording sections 23 and 26 on the front or back of these cards 21 and 24.
The image recording units 23 and 26 convert the heights into gradations based on the sculpture image (stereoscopic image) data obtained by three-dimensionally measuring the faces of the holders of the cards 21 and 24 and record them as images. A monocolor image in which the height of image data is converted to black and white or a gradation of density of a specific color, and a full-color image in which the height of stereoscopic image data is converted to gradation of hue and saturation are recorded.
The recorded image may be from the front, side, or back of the face of the holder, from another angle, or from the upper body, from the neck, or from FIGS. 6 (A), (B), As shown in (C), only the part including the eye, nose, and ear, which are the most characteristic of the individual, may be used. An image specific to the holder may be used instead of the image of the face of the holder.

As described above, in the case of a magnetic card, there are a magnetic card provided on the front surface and a magnetic card provided on the back surface. The reading device is of a type in which reading is performed by passing a magnetic stripe portion through a slit. There is a type in which the entire card, such as a bank card, is read by sucking it into the apparatus. In particular, in the case of a reading type through a slit, an image recording unit is provided on a surface opposite to a surface having a magnetic stripe so that a recorded image can be read simultaneously with a magnetic stripe reading operation. be able to. The image recording unit for recording an image in this manner is provided in an area avoiding the magnetic stripe, the signature area, and the embossed area. For example, the image recording unit may be provided in the embossed area or may be provided so as to overlap these areas. . Of course, it goes without saying that the card can be applied not only to the magnetic recording card and the IC card as described above, but also to an optical recording card and other cards.

Ears, mouth, eyes,
The positions, shapes, and heights of the eyebrows, nose, chin, and the like differ from person to person as in the case of fingerprints, and can be used as stable information even after many years. Since such three-dimensional information is converted into two-dimensional image information and the face of the owner or the holder is used as the characteristic information of the recorded image, it is possible to improve the accuracy of discriminating the owner or the holder from the recorded image. it can. Moreover, since the password and the recorded image based on the three-dimensional image are used for collation, a highly reliable system can be realized as compared with the conventional system. In a recorded image based on a stereoscopic image,
Although noise such as scratches will greatly affect recognition accuracy, facial feature information that differs significantly from each other will be used.
By operating the similarity based on the determination criterion, it is possible to realize a system that can sufficiently cope with noise such as scratches.

According to the present invention, for example, by inserting a medal recording an image of the face of the holder into the card,
The appearance can be improved and the added value of the card can be increased, and the sculpture image can be directly compared with the face of the owner, so that plagiarism can be prevented and the image is mechanically identified. As a result, security can be enhanced against forgery and alteration. Also, when used at unmanned terminals or unmanned opening / closing entrances, for example, by enabling the face to be displayed on the monitor, a surrounding third party can check the face against the face of the person against plagiarism etc. Can provide a possible function.
