Description

The present invention discloses a chip having analog information having a plurality of elements and a method of using the chip. In particular, IC cards, credit cards, cash cards, prepaid cards, magnetic cards, etc., and examination tickets, insurance cards, railways, insurers, social insurance / social welfare, local mall associations, various It is related to the property authentication in the identity authentication of membership card such as merchandise wholesaler, next generation IC card, local government, telecommunications industry, electronic money, network, etc.
It also relates to certified products that can be applied to car keys, house keys, coin locker keys, and the like.

In modern society, personal authentication plays an important role in terms of security, such as credit cards, ID cards, and keys.
This personal authentication method can be broadly divided into:
I. Something you know (password)
B. Something you have (property certification)
C. There are three types of biometric features (including behavioral authentication) (something you are) (biometric authentication) that complement each other to build a high level of security. As specific examples of property authentication proved by the above, various methods such as a magnetic card and an IC chip have been proposed.

As an authentication product for property authentication in the personal authentication, a secret image is concealed using moiré fringes, and a secret image appears when an interference image forming body is covered on the pattern, such as a card. Conventional examples of authenticity determination have been proposed.
However, since the invention using moire fringes for authenticity determination is to visualize a planned secret image using an interference image forming body, there is only one type of interference image forming body for visualizing the secret image. .
Therefore, when the interference image forming body or the authenticity determination device equipped with the interference image forming body flows out or the card is illegally crossed, the entire system including the card must be changed. Therefore, there has been a problem that the cost for dealing with fraud increases as the number of authentication systems increases.

Conventionally, in the IC chip with the highest security level, the basic security of the IC chip is how to protect the data to be recorded. If this data is leaked to an external person or analyzed, The authentication product (IC card) is easily forged. Therefore, in order to prevent unauthorized access to the IC card to protect this data, tamper resistance is improved by hardware technology, encryption (public key, etc.) by software technology, user authentication, access management Advanced technology such as (data protection) and risk management by system technology is required.
This leads to an enormous and complicated security system for certified products that use IC chips. In the case of IC chips, the value obtained from the result of authenticity determination (for example, points issued by small stores) Even in the case where the IC card is low, a terminal device having very high technology and security management are required, and as a result, it has become one of the obstruction factors for widely spreading IC cards.

2. The object to be analyzed is a figure or substance arranged on an analog chip, and has a planar (two-dimensional) or three-dimensional (three-dimensional) structure.

3. The element of the object to be analyzed refers to an object from which the shape, color, size, position, physical properties, etc. of the object to be analyzed are extracted.

4. A two-dimensional analog chip (two-dimensional chip) is a kind of analog chip having a planar analysis object (figure / substance) drawn with paint such as printing.

5. A three-dimensional analog chip (three-dimensional chip) is a kind of analog chip that includes an object to be analyzed (figure / material) having a three-dimensional structure.
Note that the three-dimensional analog chip may be classified as two-dimensional depending on the observation method of the observation unit.
In other words, when observing a certain three-dimensional chip, it is two-dimensional in an observation unit using a normal camera, but three-dimensional in an observation unit (such as a stereo camera) that can analyze a three-dimensional structure. Can be processed as

Framing means connecting extracted elements with lines in accordance with conditions to draw a frame figure, and in the case of a chip having a three-dimensional structure, a frame diagram having height information is obtained.

A first embodiment relating to the analysis and encoding of the analog chip (chip 1) will be described below with reference to FIGS.
The feature of the chip 1 of the present embodiment shown in FIG. 1 is that an analyte having various elements is randomly arranged on the base.

  The chip 1 is an analog chip including a base 3 having an intermediate color on which an object to be analyzed is arranged. The base 3 is divided into columns X1 to X10 and rows Y1 to Y6. The base 3 is provided with objects to be analyzed of irregular shapes 5a to 5d, square shapes 6a to 6e, and circular shapes 7a to 7i. In each of these shapes, the shapes filled with diagonal lines are red, and the white shapes are blue. Show.

The measurement points 8 of the chip 1 are the four corners of the chip, and the positions of the grid and the object to be analyzed are obtained from the four measurement points.
Note that Japanese Patent No. 2644812 is known as an automatic image recognition method, and various automatic image recognition techniques can be employed.
The measurement points are not limited to the four corners of the chip, and a specific figure or the like can be arbitrarily set as the measurement points.

Next, chip analysis data (Ka) of the chip 1 and chip code data (F) obtained by encoding the chip analysis data (Ka) will be described.
The outline is that when the analog chip 1 is observed with the observation means (A), chip analysis data (Ka) is obtained. Next, when this chip analysis data (Ka) is encoded with the encoding method data (a), chip code data is obtained. (F) is obtained.

First, Table 1 shows an example of observation means (A) defined in advance by an observation unit that observes the chip.
The observation means data (A) is a symbol for specifying the performance and observation method of the observation unit that observes the analog chip.

Next, Table 2 shows the relationship between the encoding method data (a) for encoding the chip analysis data (Ka) obtained by the observation means and the encoding method.
Note that the encoding method data (a) is a symbol for specifying an encoding method algorithm including means for converting chip analysis data from the observation unit 61 described later from analog to digital.

Further, the relationship between the observation means data (A), chip analysis data (Ka), and encoding method data (a) for the chip code data “F1” to “F6” shown in FIGS. 3 shows.
The chip code data (F) is data obtained by encoding the chip analysis data (Ka) obtained by observing the analog chip with the observation means using the algorithm of the encoding method data (a).

The contents of the encoding method shown in this table will be described based on the analog chip 1a shown in FIGS.
First, FIG. 1 is a plan view of an analog chip 1a, chip analysis data “Ka1” obtained by observing the analog chip 1a with a full-color observation device, and encoding method data “a1” (all information It also serves as a diagram of the chip code data “F1” encoded in (Extraction).
Now, the encoding method for obtaining the chip code data “F1” shown in the first row of Table 3 will be further described.
In the first stage, the analog chip 1a is observed, and the observation means data “A1” at this time is “all information” of the elements of the chip 1a (in this embodiment, full-color image data). Data “Ka1” is obtained.
In the second stage, the chip analysis data “Ka1” obtained by the observation means “A1” is encoded. The content of the encoding method data “a1” at this stage is to extract all information of the data.

Through these two steps, the analog chip 1a is encoded into chip code data “F1” shown in FIG. Therefore, in this encoding method, the chip analysis data “Ka1” and the chip code data “F1” are the same.
That is, FIG. 1 represents the chip 1a itself, and also represents the information of the chip analysis data “Ka1” and the chip code data “F1”.
Therefore, it is possible to construct an authentication system that employs only this encoding method data “a1” (extracts all information).
This also indicates that a simplified authentication system that employs only this encoding method data “a1” (extracts all information) can be incorporated into the authenticity determination system of the present invention.

Next, chip code data “F5” obtained by encoding the chip 1a shown in Table 3 and FIG. 5 will be described.
In the first stage (observing the chip and generating the chip analysis data), the observation means data “A1” for observing the chip 1a is extraction of all the element information, so that the chip analysis data “Ka1” is obtained. .
In the second stage, the chip analysis data “Ka1” obtained in the first stage is encoded. The encoding method data algorithm at this time is “a2” (extracts a red graphic), “a4” (extracts a circular graphic), and “a7” (framing the center of gravity of the selected graphic). is there.
The chip code data “F5” having the frame graphic 9b is obtained by the two steps.

Furthermore, the process of encoding the chip code data number “F6a” shown in Table 3 and FIG. 6 will be described.
In the first stage, since the observation means of the chip code data “F6a” shown in FIG. 6 is “A3” (uses a filter that excludes red), a figure having elements of colors other than red is extracted. Chip analysis data “Kc1” shown in FIG. 3 is obtained.
In the second stage, the encoding method data is first encoded with the chip analysis data “Kc1” by “a4” (extracting a circular figure), and then “a7” (the centroid of the extracted figure is framed). Do.
Through the two steps, chip code data “F6a” including the frame graphic 9c is obtained.
Other chip code data “F2”, “F3”, and “F4” are also the same as the above-described encoding method, and a specific description thereof will be omitted.

Next, an encoding method in the case where the element position information is chip code data will be described with reference to FIG.
In the first stage, the observation means data = A1 (all information), and chip analysis data “Ka1” is obtained.
In the second stage, encoding method data = a2 (extracts a red graphic) + a4 (extracts a circular graphic) + a8 (detects position information of the extracted graphic)
When the chip code data is obtained under the above conditions, the position of the circular figure is the circular figure 7a (X8 · Y5) figure 7c (X1 · Y5) figure 7g (X4 · Y2) figure 7h (X8 · Y1), This position information can be used as chip code data.
That is, the chip code data “F” of the system of the encoding method of this embodiment is
“F7” = “(X8 · Y5), (X1 · Y5) (X4 · Y2) (X8 · Y1)”
Can be.

  In this encoding method, there are methods such as zigzag scanning for the order of extracting figures, but in this embodiment, search is performed from the right to the left of line Y6, and when the line end is reached, the next line is also searched from the right end. Finally, by adopting the scanning method to reach the grid of (X1 · Y1), the chip code data “F” different from the embodiment can be easily obtained by changing the scanning order.

In this encoding method, since the position information of each element is represented by character information in the chip code data “F”, the amount of information can be reduced.
In addition, for example, a red element and an irregular figure element can be selected, and the number of grids to which the figure relates can be used as chip code data. Further, a figure having an arbitrary color element and a figure element can be obtained. It is possible to arbitrarily select an encoding method that can be expressed in various ways, such as extracting and using the number of figures as chip code data.

  As described above, a plurality of encoding methods and a plurality of observation methods such as the scanning order of the elements (shape, size, color) of the object to be analyzed, the area of the elements, the number of elements, and the frame diagram in which the elements are framed. Thus, various chip code data can be obtained from one chip.

In this embodiment, the base 3 since it aims to enable analyzing was neutral but short the analyte, can be arbitrarily selected in any color, it may be transparent .

  Although the chip 1a has been described two-dimensionally, it is needless to say that the encoding method of this embodiment can be adopted even with a three-dimensional chip in which the base 3 is transparent and each element exists in a three-dimensional space. .

  The circular graphics 7a to 7i and the square graphics 6a to 6e are graphics having types, but their positions are indefinite and are randomly arranged. However, in the case of a three-dimensional structure, it may be arranged by a method such as free-falling and attaching from the top, or by mixing an object to be analyzed with resin powder such as acrylic resin, Even when solidified with a solvent, an analog chip in which the analytes are distributed randomly can be easily obtained.

These figures are examples of the object to be analyzed, and it goes without saying that various substances having various shapes, sizes, colors, and magnetism can be used as the object to be analyzed.
If the chip has a three-dimensional structure, even if a malicious person tries to copy the chip, it is very difficult to copy the three-dimensional structure, so that the effect of suppressing forgery can be obtained.

  The configuration of the chip and the encoding method according to the second embodiment will be described with reference to FIGS.

Note that the symbols and the like given to the drawings of the present embodiment are the same as those of the above-described embodiment, and the functional effects thereof are the same except for those specifically described, and thus the description thereof is omitted.
The feature of the present embodiment is that it is encoded by providing the code table 51 to the code table 53 shown in FIGS. 9A to 9C corresponding to the analysis object of the analog chip 1b shown in FIG. is there.

  The analog chip 1b of this embodiment includes an X axis indicating the horizontal direction, a Y axis indicating the vertical direction, and a Z axis indicating the height, and the pattern of the cut surface on which the graphic information 51 appears is continuous in the Z axis direction. Are formed on a three-dimensional chip 50 provided (so-called Kintaro shape).

One method for manufacturing the three-dimensional chip 50 will be described with reference to FIG.
As shown in FIG. 7, the three-dimensional chip focuses an analyte bar 45 in which an analyte 44 is continuously provided in a Z-axis direction inside a transparent base material 48, and the analyte bar 45. The focusing bars 46a to 46c are formed to have different patterns.

By cutting the focusing bars 46a to 46c, end pieces 47a to 47c are obtained.
Further, when these end pieces 47a to 47c are formed on one chip, a three-dimensional chip 50 is obtained.

  At this time, by using the fact that a plurality of end pieces 47 having the same chip code data can be created from the convergence bar 46, for example, the end piece 47 may have a specific number such as a store number of a financial institution belonging to the consumer credit industry. It is also possible to have specific individual information.

  In addition, after collecting three pieces of end pieces 47 having different patterns and forming them on one chip, avoid this combination, and form a chip by combining end pieces having a unique analysis object arrangement not shown. Thus, it is possible to easily mass-produce three-dimensional chips having different analyte arrangements.

Next, the visibility of the three-dimensional chip in the present embodiment will be described.
First, as shown in FIG. 8B, when the three-dimensional chip is viewed obliquely from above, the side surface of the object to be analyzed is visible, so there is little light transmission. Next, the three-dimensional chip is shown in FIG. Thus, since the cross-sectional shape of the object to be analyzed can be seen from the vertical direction, a large amount of light from the back of the chip is transmitted through the transparent base material 48. Therefore, the amount of light between the oblique observation and the vertical observation It can be easily confirmed that a three-dimensional structure is provided by paying attention to the fact that changes.

In this way, it can be confirmed that the structure is simply a three-dimensional structure even with the naked eye. The analog chip in this embodiment can be easily confirmed with the naked eye that the structure of the object to be detected is continuous with the Z axis. It can be used for simple chip authentication methods.
The method for increasing the visibility of the three-dimensional structure is not limited to the method of this embodiment, and various methods such as a method using a difference in material refractive index can be adopted.

Next, the encoding method of the present embodiment will be described with reference to FIGS.
The observation means data of the chip analysis data “Kb1” in this embodiment is all information (in this embodiment, full-color image data) “A1” of the elements photographed (analyzed) by the observation unit (camera), and the chip The observation means data of the analysis data “Ke1” is “A3”, and the observation means data of the chip analysis data “kf1” is “A2”.
Also, the encoding method of the present embodiment is characterized in that chip code data can be expressed as a character string by assigning an assigned number or the like to graphic information.

Table 4 below is a code table showing the relationship between the encoding method and the encoding method data (a).

The encoding method data in Table 4 will be described.
FIG. 9A is a code table 51 showing an assigned number 57 assigned to the graphic information 51a. For example, the triangular figure is assigned with a number “1”, and this assigned number is the symbol of the triangle. The encoding method data (a) at this time is “a9” in Table 4.
FIG. 9B shows the graphic information as numerical information 52a which is the form of numbers in order to make it possible to read the assigned number visually, and the encoding method data at this time Is “a10” in Table 4.
The upper part of FIG. 9C is a diagram for explaining that the chip code data is changed by changing the assignment number 57 related to the encoding when the graphic information which is the chip analysis data is encoded. The lower part is a diagram showing that the number shape report indicating the number can be simply treated as graphic information and an assignment number different from the number represented by the shape can be provided, and the encoding method data at this time is shown in Table 4 "A11".

That is, FIGS. 9A to 9C show code tables 51 to 53 having different assigned numbers 57, respectively. Therefore, it is shown that the chip code data (F) obtained from the analog chip can be changed only by changing the encoding method data (a) when the chip is encoded.
For example, a triangle to which code “1” is assigned in the code table 51 of FIG. 9A is assigned “3” in the code table 53 of FIG. 9C.
Therefore, even for the same analyte, the chip code data (F) can be made completely different by changing the encoding method.

This means that in the authentication system of different enterprises card, analog it becomes possible to construct a authentication system independently by varying the encoding method, for example, by eavesdropping the line of a company system chip Even if the number (T) and the chip code data (F) are obtained illegally and an attempt is made to perform "spoofing" illegally in other authentication systems, they will be wiretapped if they differ from the encoding method used in the authentication system. Since the data is easily identified, it is possible to obtain the effect of extremely high reliability.

Next, an example of encoding the three-dimensional chip 50 will be described with reference to FIG.
FIG. 10A shows chip analysis data “kd1” having color information obtained by analyzing an analog chip, and the filled graphic information 51a indicates that the color is red, and is shown only by the outline. The graphic information indicates that the color is blue, Y1 to Y4 indicate row numbers, and X1 to X12 indicate column numbers.
FIG. 10 shows chip code data “F7” obtained by encoding the chip analysis data “Kb1” by extracting all information from the encoding method data “a1”.
(B) of FIG. 10 is chip code data “F10” in which the number is given to the analysis object by the code table 51 based on the encoding method data “a9” in Table 4.
In the chip code data “F10”, all elements of the graphic information are encoded based on the encoding method data “a1” (extract all information).
FIG. 10C shows chip code data “F11” assigned a number based on “extract data of Y4 row” of the encoding method data (a12) in Table 4.

Next, an example of chip code data (F) obtained when the analysis method of the analog chip 1b in FIG. 10 is changed will be described with reference to FIGS.
There are various methods for obtaining the chip code data of this embodiment, but a typical method will be described.
First, FIG. 11A shows that the chip analysis data “Kd1” shown in FIG. 10A is encoded by the chip encoding method data “a3” (blue figure is extracted) shown in Table 2. The chip code data “F8a”.
FIG. 11B shows chip code data “F12a” obtained by further encoding the chip code data “F8a” with the encoding method data “a9”.

  12A shows chip analysis data “Kf1” in which the blue graphic information is excluded by the filter of the observation means data “A2” shown in Table 1, and chip code data encoded by the encoding method. “F8a” is shown, and FIG. 12B shows chip code data “F13a” obtained by encoding the chip analysis data “Kf1” using the code table 51.

In this embodiment, the chip code data may be obtained by selecting a row or a portion. For example, only the Y4 row of the chip code data becomes the chip code data “F”. (Same as the contents of Tables 1 to 3 above.)
Observation means data “A1” + encoding method data “a1” + “a12”
= 213712286415 (see FIG. 10B, line Y4) "F14"
Observation means data “A3” + encoding method data “a1” + “a12”
= 1312861 (see FIG. 11 (B), line Y4) “F15”
Observation means data “A2” + encoding method data “a1” + “a12”
= 27245 (see FIG. 12B, line Y4) “F16”
Thus, different chip code data can be easily obtained from one analog chip.

When the observation unit detects all information of the chip of this embodiment, a specific example of the Y4 row of the chip code data “F1” obtained when the encoding method data is changed is as follows:
In the case of code table 51: 213712286415 (see FIG. 10B, line Y4) “F14”
In the case of the code table 53: 136531127839 (see FIG. 11C) “F17”
It is.

  These data are organized and shown in Table 5 below.

In this embodiment, when obtaining the chip code data “F” from one chip, the original chip code data is obtained by changing the coding method from the code table 51 to the code table 53 as shown in FIG. Furthermore, original chip code data can be obtained by changing the observation means.
Also in this embodiment, when obtaining the chip code data of the analog chip 1, different chip code data “F7” to “F17” can be easily changed by changing the observation means or by changing the encoding method. You can get it.

When obtaining the chip encoded data, color elements can be extracted and the number of figures having the color can be used as encoded information.
It is also possible to arbitrarily select various encoding methods such as selecting color elements and graphic elements (for example, red / triangle) and using the graphic number as encoding information.

The chip of this embodiment can be handled in the same way as a two-dimensional chip depending on the analysis method, and a plurality of images taken by an observation unit such as a camera (stereo vision) whose relative positional relationship and orientation are known. It is also possible to obtain chip code data by coding method data (a) for reconstructing the chip analysis data (Ka) on the three-dimensional coordinates, with the image of the sheet (usually two) as chip analysis data (Ka). Is possible.

In the encoding method reconstructed on the three-dimensional coordinates, if the transparent base material 48 is treated as a space, it is possible to use chip information that the analytes 44 are arranged in a column.
At this time, the position information (coordinates) of the feature points of the analyte in the three-dimensional space may be used as the chip code data (F) by observing the analyte, and as means for obtaining the coordinates of such feature points, There is known a method for estimating a three-dimensional position by using measurement points 8 as a plurality of reference points in a three-dimensional space in which a positional relationship is determined in advance.
Specifically, Japanese Patent No. 3020898 is known as one method for obtaining the coordinates of a point in such a three-dimensional space.

  Therefore, this three-dimensional chip information is adopted as the chip code data “F”, and the chip data “Ta” in which the position information in the three-dimensional space of the analysis object stored in the analog chip DB is stored as the reference data. It is also possible to make a system for verifying authenticity by comparing the two, and it is extremely effective to prevent forgery of a chip because it is very difficult to duplicate a three-dimensional chip having chip information of such a structure. .

Next, an analog chip 1C having a mesh structure 20 using a shape (moire fringes) generated when two different patterns of meshes are superimposed according to the third embodiment will be described with reference to FIGS. .
Note that the symbols and the like given to the drawings of the present embodiment are the same as those of the above-described embodiment, and the functional effects thereof are the same except for those specifically described, and thus the description thereof is omitted.

First, since the analog chip 1c of this embodiment has a structure in which meshes are overlapped and solidified with resin, the analog chip 1c can be handled as a two-dimensional structure chip depending on the performance of the observation unit. It is also possible to handle it as a chip.
The analog chip 1c having a unique structure according to the present embodiment is easy to manufacture, and further has a three-dimensional structure in which mesh structures are superimposed. Therefore, forgery (copy) made by photographing can be easily performed by three-dimensional measurement. Can be found.

  FIG. 13 shows chip analysis data “Kg1” of the analog chip 1C, and chip code data “F14” obtained by encoding the chip analysis data “Kg1” with the encoding method data (a1) “extract all information”. Is also expressed. In this figure, the solid line indicates the red mesh fiber, and the broken line indicates the blue mesh fiber. However, the solid line of the outer frame is black, and the four corners of the outer frame are It is a measurement point.

FIG. 14A shows chip analysis data “Kh1” obtained using a filter that excludes the blue color of the observation means data “A2”, and FIG. 14B shows the observation means data “A3”. This is chip analysis data “Ki1” obtained using a filter that excludes red.
By changing the observation means data in this way, different chip analysis data (Ka) can be obtained. Furthermore, different chip code data “F15” and “F16” can be easily obtained by encoding all the information of the analysis data. Further, the chip code data (F15) can be obtained using the mesh code table 54 shown in FIG. ) Can be obtained.

In the mesh code table 54, the figures from triangles to octagons are classified from A to F as typical mesh figure structures of the present embodiment.
For example, “C” (pentagon) in the mesh code table 54 of FIG. 15 is extracted from the chip analysis data “Kh1” shown in FIG. 14A, and the arrangement of the extracted figure is defined as chip code data. Then, chip code data “F17” shown in FIG. 16 is obtained.

  As described above, various chip information can be obtained also by the analog chip having the mesh structure of the present embodiment.

  In the present invention, when excluding or extracting an element (eg, blue data), a method is described in which a filter is provided in the observation unit to extract an element of a specific substance, but not limited to such a filter. For example, it is also possible to adopt a method of irradiating infrared rays and extracting elements of an analyte that are visible with infrared rays. These observation means are arbitrarily determined, and each means has different effects. .

  For example, when a special observation method is used for the observation unit, it is necessary to store the corresponding chip data “Ta” in the analog chip DB 66. The special feature can be expected to make it more difficult to forge the observation section.

Further, an analyte is kneaded into a transparent base material as a chip structure to create an analog chip in which the analyte is randomly distributed in three dimensions, and the analyte in the analog chip is known 3 It is possible to analyze with the 3D shape measurement system and use the position information of the analysis object as chip code data, or the framing of the position information of the analysis object may be used as the chip analysis data. By kneading various analytes into the base material, the observation means (A) and encoding method data (a) are uniquely set for each authentication system, and each authentication system builds its own authentication system. Independence can be ensured.
In addition, a substance having various physical properties may be employed for the analyte, and for example, a magnetic storage medium having a specific element may be employed.
In such an analog chip, the objects to be analyzed are randomly distributed in a three-dimensional form, so that it is extremely difficult to forge the same one, and unauthorized use can be prevented.

  In the above embodiments, different types of analog chips have been described, but it goes without saying that analog chips of different types may be used in consideration of the characteristics of these analog chips.

Further, in the present invention, in an authentication system for cards of different companies, it is possible to easily construct an original authentication system by changing the code table. Even if chip data is obtained, it cannot be used in other companies' systems at all, so that the reliability and independence of the authentication system can be increased.

  The analog chip analysis and encoding method has been described so far. Hereinafter, an authenticity determination system using an analog chip in this embodiment will be described with reference to the drawings. Note that the symbols and the like given to the drawings of the present embodiment are the same as those of the above-described embodiment, and the functional effects thereof are the same except for those specifically described, and thus the description thereof is omitted.

Conventionally, many authenticity determination systems using an IC card or the like have been disclosed in a network society.
Although this conventional technique is very excellent, these techniques have confirmed the authenticity of an authentication object equipped with an IC by reading out digital data stored in the IC or the like.

  On the other hand, in this embodiment, focusing on the diversity of analog chips such as color, material, size, shape, etc., analyzing elements with enormous information and further encoding them to match the level of security. Therefore, we propose an authentication system using an analog chip that can support high security levels.

First, an embodiment of an analog chip card authenticity determination system will be described with reference to FIGS.
The greatest feature of the authenticity determination system shown in the present embodiment is that the encoding method data (a), which is an algorithm when the chip analysis data “Ka” is encoded by the code output unit 78, is remotely operated remotely or autonomously. The point is that it can be changed.
Note that the symbols and the like given to the drawings of the present embodiment are the same as those of the above-described embodiment, and the functional effects thereof are the same except for those specifically described, and thus the description thereof is omitted.

First, an outline of the authenticity determination system according to the present embodiment will be described with reference to FIG.
First, the authentication object 4 includes an authentication object 4 including a chip number display 2 that visually displays an analog chip number (T) that is an identifier ID, a barcode 27 that is displayed as a barcode, and the analog chip 1. ,
And Bakodori over da 60 for reading the information of the analog chip number (T) of the bar code 27 of the authentication object 4 (reading unit), an analog chip 1 whose position is specified by the positioning unit 40, observes the analog chip 1 An observation unit 61, a first information processing unit 62a, and a second information processing unit 90a are provided.
The first information processing unit 62 a and the second information processing unit 90 a of the information processing unit of this embodiment are connected via the information network 100.

  The first information processing unit 62a includes a terminal input unit 72, a chip information storage unit 63, an analog chip encoding unit 76 that converts chip analysis data (Ka) into chip code data (F), and an output unit 82. The code data group 84 is transmitted to the second information processing unit 90a via the information network 100.

  The second information processing unit 90a collates the input unit 83 to which the code data group 84 sent from the information network 100 is input, the data of the code data group 84 and the data from the analog chip DB 66 (not shown). A code determination unit 85 that determines authenticity and a determination information storage unit 86 that stores the determination result.

Next, the role of the first information processing unit 62a in the authenticity determination system of this embodiment will be described with reference to FIGS.
Note that there are two types of systems 76A and 76B in the analog chip encoder 76 of this embodiment shown in FIG.

First, the analog chip encoding unit 76A of the first information processing unit 62a-1 shown in FIG. 18 has a remote encoding method data output unit 77, and receives remote encoding method data (R ) Makes it possible to change the encoding method data (a) when encoding the chip analysis data (Ka).

  Further, the analog chip encoding unit 76B of the first information processing unit 62a-2 shown in FIG. 19 includes an autonomous encoding method data output unit 88, and the first information processing unit 62a-2 itself has chip analysis data. The encoding method data (a) for encoding (Ka) can be changed.

First, an embodiment in which the encoding method data (a) can be changed remotely will be further described based on FIG.
The first information processing unit 62a-1 receives signals from an input unit such as an observation unit (camera), a barcode reader 60 that is a reading unit of an analog chip number (T), a keyboard (not shown), and a pointing device. A terminal input unit 72, a chip information storage unit 63, an analog chip encoding unit A, and an output unit 82 are provided.

The chip information storage section 63 stores observation means data (A) that can specify the accuracy and observation method of the observation section 61, an analog chip number (T), and chip analysis data (Ka). The data (A) and the analog chip number (T) are output to the information network 100 as a part of the code data group 84 via the output unit 82.
On the other hand, the chip analysis data (Ka) is encoded by the encoding method algorithm (a) output from the remote encoding method data output unit 77 by the code output unit 78 and output as the chip code data (F). Is output to the information network 100 as part of the code data group 84.

  Now, if the remote signal 73 (R) in this embodiment is recorded on the second information processing unit 90a managing the authentication system, it is transmitted from the first information processing unit 62a to the second information processing unit 90a. It is possible to authenticate that the coming encoding method data (a) is the encoding method data (a) changed by the remote signal (R), and as a result, authenticity of the first information processing unit 62 that has transmitted. It can be a means of confirming.

  The remote signal 73 (R) enables the encoding method data (a) output from the remote encoding method data output unit 77 to be changed by remote operation from the second information processing unit 90 side. When the code data group 84 is communicated from the unit 82 via the information network 100, even if the code data group is stolen by wiretapping or the like, the algorithm of the encoding method data (a) is changed by the remote signal 73. If this happens, the sign determination unit 85 in the second information processing unit 90 will determine that it is a “NG” fake, so it is possible to prevent illegal acts such as shopping by impersonating the so-called cardholder. It is possible.

  In the past, it was necessary to take measures such as contacting the cardholder and changing the card when there was "spoofing" that was illegal use of a magnetic card, etc. In this example, the card must be changed. In addition, by delivering the remote signal 73 (R) from the second information processing unit 90 side, an unprecedented effect that crimes such as unauthorized use of the card can be prevented can be obtained.

Next, an embodiment provided with an analog chip encoding unit B having a different encoding method data (a) changing method will be described with reference to FIG.
The present embodiment is different in that it has an autonomous encoding method data output unit 88 instead of the remote encoding method data output unit 77 of the above embodiment, and this point will be described.
In the present embodiment, the encoding method data (a) is output by an autonomous encoding method data output unit 88 that autonomously changes based on a regular or constant algorithm, and the code output unit 78 is output by this encoding method. The chip analysis data (Ka) is converted into chip code data (F) by control.

  The effect of the configuration of the first information processing unit 62a-2 shown in FIG. 19 is that the encoding method data (a) is changed by the autonomous encoding method data output unit 88 based on a regular or fixed algorithm. Therefore, when a malicious person eavesdrops on the chip code data etc. in the information network 100 and tries to impersonate the card owner, the encoding method data (a) is based on a regular or fixed algorithm. If the malicious person does not know the changed coding method data (a) and the corresponding chip code data (F), the correct code data group 84 is transmitted and “spoofing” is performed. It is possible to prevent unauthorized use.

Next, the second information processing unit 90a that processes the code data group 84 transmitted from the first information processing unit 62a via the information network 100 will be described with reference to FIG.
The second information processing unit 90a includes an input unit 83 that receives the code data group 84 transmitted via the information network 100, a code determination unit 85 that determines the authenticity of the analog chip, and an analog for each observation means (A). An analog chip DB 66 that is an analog chip database that stores chip data (Ta) corresponding to the chip number (T), and a determination information storage unit 86 that records a result of the code determination unit 85 are provided.

  First, when the code data group 84 is received by the input unit 83, the observation means data “A1” and the analog chip number data “T238” of the code data group 84 are transferred to the analog chip number processing unit 91. Therefore, when the analog chip number processing unit 91 makes an inquiry to the analog chip DB 66, the chip data “Ta1” of the analog chip number “T238” that is previously observed and registered with the observation means data “A1” is read as reference data, and the code dummy The data is output to the data generation unit 92.

  Next, the code dummy data generation unit 92 encodes the chip data “Ta1” with the encoding method data “a1” from the code data group 84 and outputs the dummy data “f1” to the code verification unit 95.

The collation method of the code collation unit 95 will be described. The chip data “Ta1” recorded in advance in the analog chip DB 66 is data obtained by observing the analog chip “T238” with the observation means data “A1” (all information). This is the reference data for the analog chip “T238”.
Incidentally, the chip data “Ta2” described in the analog chip DB 66 is data obtained by observing the analog chip having the analog chip number “T245” with the observation means “A1” (all information).
Thus, the significance of storing the chip data (Ta) corresponding to the analog chip number (T) for each observation means (A) is to increase the accuracy for eliminating fakes in the authenticity determination in the sign determination unit. .

More specifically, the analog chip number processing unit 91 of the code determination unit 85 performs the corresponding chip data (Ta) based on the observation means data “A1” and the analog chip number “T238” of the transmitted code data group 84. ) To the analog chip DB 66, and the chip data “Ta 1” obtained by this inquiry is sent to the code dummy data generation unit 92.
Further, the code dummy data generation unit 92 encodes the chip data “Ta1” distributed from the analog chip number processing unit 91 based on the encoding method data “a1” of the encrypted data group, thereby generating the dummy data “Ta1”. f1 "is generated.

  Next, the code verification unit 95 receives the chip code data “F1” distributed from the encrypted data group 87, and then the dummy data “f1” transmitted from the code dummy data generation unit 92 and the chip. The code data “F1” (F) is collated to determine authenticity.

Therefore, the dummy data “f1” obtained by encoding the chip data “Ta1” with the encoding method data “a1”, and the chip code data “F1” of the analog chip “T238” transmitted via the information network 100. ”Means that the observation means and the encoding method are the same, so that“ OK ”is determined to be true if“ f1 ”and“ F1 ”are within the range of errors that occur in the observation, etc. A series of processes for determining the authenticity of the recorded analog chip 1 is completed.
The significance of the dummy data (f) in this process is to increase the recognition accuracy for eliminating the fake analog chip 1.

In the configuration shown in FIG. 19 to FIG. 20, a signal synchronized with the autonomous encoding method data output unit 88 provided in the first information processing unit 62 is also output on the second information processing unit 90 a side, not shown. A synchronous encoding method data output unit having a time table is provided, and the code data group 84 itself transmitted from the first information processing unit 62 is encoded by the encoding method data (a) from the synchronous encoding method data output unit. It is possible to determine authenticity, and various security systems can be constructed.

Although the present embodiment has been described with reference to a schematic diagram, the present embodiment is also a system including the following steps without being caught by the above configuration.
That is, 1, the stage of observing the analog chip by the observation unit 61,
2, obtaining the chip analysis data (ka) output from the observation unit;
3, a step of encoding chip analysis data (ka) to obtain chip code data (F), a step of generating dummy data (f) from pre-stored chip data (Ta),
5, collating dummy data and chip code data;
6, outputting the judgment result;
Computer system with
It is.

  Therefore, the system provided with the above steps does not depart from the technical idea of the present embodiment even if the system has a configuration different from that of the embodiment.

  Needless to say, a signal output from an IC chip such as a contact IC or a non-contact IC may be an analog chip number (T), and a mechanism for receiving the signal may be employed in the reading unit.

  Furthermore, the observation means (A) can employ various methods. For example, the observation means (A) can be read using visible light, or can be read using radio waves or light of other wavelengths. . That is, chip data corresponding to the analog chip number based on the original observation means (A) is registered in the analog chip DB 66 in advance, and the observation section conforming to the standard of the observation means (A) is designated as the first information processing section 62. If it is connected and adopted, it is possible to construct an original card authenticity determination system as needed.

It is also possible to change the observation means automatically or by exchanging the filter of the observation means with a remote signal from the analysis data collating unit 65.

  Since the encoding method employed in the authenticity determination system of this embodiment is program data for calculation processing, for example, when a code data group is wiretapped, a malicious person in the terminal input unit is illegal. Even if data is input, it can be easily handled by changing the encoding method, so there is no need to invalidate the card itself. This enhances the convenience of the card for the user who uses the card authenticity determination system, and also protects the user's property, hindering the intention of a malicious person to counterfeit the card. It is also what you do.

  Next, an embodiment provided with an encryption / decryption function that copes with fraud such as eavesdropping in the information network 100 will be described with reference to FIGS.

  Regarding the system for encrypting and encoding the chip code data (F) of this embodiment, the system for changing the encoding method data (a) by remote operation (remote signal (R)), the encoding method data ( There is a system in which a) is changed by the autonomous encoding method data output unit 88.

First, an outline of the entire system for encrypting and decrypting chip code data (F) will be described with reference to FIG.
Note that the symbols and the like given to the drawings of the present embodiment are the same as those of the above-described embodiment, and the functional effects thereof are the same except for those specifically described, and thus the description thereof is omitted.

  First, data related to the analog chip 1 input to the terminal input unit 72 of the first information processing unit 62b is recorded in the chip information storage unit 63, and each data in the chip information storage unit is transmitted to the encryption unit 80. Of these, the chip analysis data (Ka) is transmitted to the encryption unit 80 via the analog chip encoding unit 76.

  The encryption unit 80 encrypts data required for security, and an encrypted data group 87 including the encrypted data is transmitted to the second information processing unit 90b through the information network 100 via the output unit 82. .

  Next, examples of two different modes of the first information processing unit 62b will be described with reference to FIGS. A feature of the embodiment shown in FIG. 22 is that the encoding method data (a) can be remotely controlled from outside the first information processing unit 62b.

  The authenticity determination system that transmits the encrypted data group 87 to the information network 100 according to the present embodiment is an example in which the encoding method data (a) is changed by the remote signal (R), and the first information shown in FIG. The processing unit 62b-1 is provided with a chip information storage unit 63, and the observation means data “A1” and the analog chip number “T238” stored in the chip information storage unit 63 are transmitted to the encryption unit 80, and the chip The analysis data “Ka1” is converted into chip code data “F1” by the encoding method data “a1” output from the remote encoding method data output unit 77 in the code output unit 78 and transmitted to the encryption unit 80. ing.

  The remote signal (R) transmitted to the remote encoding method data output unit 77 is preferably encrypted and transmitted when transmitted through an information network (not shown). Since the data is decoded by the unit 81 and transmitted to the remote encoding method data output unit 77, the remote signal (R) is prevented from being abused by wiretapping in the information network.

  The encryption unit 80 encrypts the encoding method data “a1”, the observation means data “A1”, the analog chip number “T238”, and the chip code data “F1”, and transmits them to the information network 100 via the output unit 82. is doing.

  The encoding method data “a1”, the observation means data “A1”, the analog chip number “T238”, and the chip code data “F1” may all be encrypted. Even if only "T238" is encrypted, it is very difficult to misuse the information. Select data to be encrypted arbitrarily according to the situation such as line traffic and load on the information processing unit. I can do it.

Next, the 1st information processing part 62b-2 which is another aspect is demonstrated based on FIG.
The feature of this embodiment shown in FIG. 23 is that the encoding method data (a) can be changed autonomously by outputting the encoding method data (a) from the autonomous encoding method data output unit 88. In addition, the data can be encrypted by the encryption unit 80.

  Next, the second information processing unit 90b to which the encrypted data group 87 is transmitted will be described with reference to FIG. 24. Each of the encrypted data group 87 transmitted to the input unit 83 via the information network 100 will be described. The data is decrypted by the decryption unit 81 and decrypted in a state where program processing is possible in the second information processing unit 90b.

  Since it is configured in this way, even if the data is stolen by a malicious person when passing through the information network 100, the content is encrypted and therefore it is very difficult to decrypt. Fraud is prevented by the difficulty of decoding.

  As the data of the code data group 84 and the encrypted data group 87 of the above embodiment, the encoding method data (a), the observation means data (A), the analog chip number (T), and the chip code data (F) are information network. For example, if the observation means data (A) or the encoding method data (a) is understood in advance on the second information processing unit 90 side, it is not necessarily transmitted. Needless to say, the data of the code data group 84 and the encrypted data group 87 may be selected according to the situation.

  FIG. 25 is a diagram showing the concept of the present embodiment, and this embodiment shows that a simple authenticity determination system can be created by omitting the encoding unit and the code dummy data generation unit using the authenticated product of the present invention. It is a figure for demonstrating.

  In this example, the analog chip encoder of the above embodiment is omitted, and the image data (chip analysis data) output from the observation unit instead of the code determination unit and the image stored in the chip data of the analog chip DB 66 are stored. The data is collated by the image data collating unit 67, and the result is stored in the image determining unit 68.

  Further description will be made based on FIG. 25. When the analysis data (Ka) (image data) of the analog chip and the analog chip number (T) for specifying the analog chip are input to the terminal input unit 72, image data verification is performed. An analog chip number (T) and chip analysis data (Ka) are transmitted to the unit 67.

  On the other hand, the analog chip DB 66 stores an analog chip number (T), which is a number for specifying an analog chip, and chip data (Ta) (image data) corresponding to the analog chip number. When the image data collating unit 67 inquires the analog chip DB 66 about the analog chip number, the chip data (Ta) stored in advance is output, and the chip analysis data (Ka) output from the terminal input unit 72 is output. The result of collation is output to the image determination storage unit 68.

The image determination storage unit stores a determination result as to whether or not the analog chip is genuine, and outputs the determination result to a display unit (not shown) as necessary.
The data example 71 will be described.
Example 1, Analog chip number = “T238” / Chip analysis data “Ka1”
Example 2, Analog chip number = “T245” / Chip analysis data “Ka2”
Example 3, analog chip number = “T256” / chip analysis data “Ka6”
Is transmitted to the image data collating unit 67, the image data collating unit 67 calls the chip data corresponding to each analog chip number.
Here, “Ka1” of the chip analysis data of Example 1 and the image of the chip data “Ta1” are collated, and if the error is within an allowable range, “OK” is determined to be genuine, and the determination result Is transmitted to the image determination storage unit 68.

If the difference between the chip analysis data “Ka2” and the chip data “Ta4” in Example 2 is not allowable, it is determined as “NG” fake, and the determination result is transmitted to the image determination storage unit 68.
As described above, since the system is simple, the system for directly comparing and determining the chip analysis data is particularly suitable for a personal authentication system for a customer management database in a small store.

  In the present invention, “JPEG” that is an image compression coding method, “Huffman code” that is a data compression method, and the like can be arbitrarily employed.

  As means for analyzing the position of the detected object in the three-dimensional space in the chip of the present invention, the detected object can be detected by a known three-dimensional shape analysis optical system such as JP-A-11-218416. Can be analyzed.

  In the present invention, as a means for outputting the analog chip number, a signal output from the IC chip is adopted, and the number may be automatically read by a mechanism for receiving the signal instead of the barcode reader 60, This configuration has the advantage that it is more difficult to produce a copy of the card.

  In the present invention, a filter can be used in the method for extracting color elements in the observation means. However, the meaning of this filter does not indicate only optical processing. For example, red, green, and blue light sources are used. For example, by observing with each light source, different chip analysis data (Ka) may be obtained, and various observation means can be arbitrarily employed.

In this embodiment, an analog chip is used for a card with a personal authentication function such as a credit card or an ID card that requires a personal authentication function.
26A shows the front surface, and FIG. 26B shows the back surface.
The analog chip 1 is provided on the surface of the base 38 of the analog chip card 30, and an analog chip number 2, a card number column 32 in which a card number 31 representing an issuer branch number, a customer number, etc. is entered, and registration A seal pasting column 35 is provided.

On the back side, a contact number 36 and a sign field 37 for personal authentication are provided.
Since it is configured in this way, for example, it is possible to register a card at a certain financial institution and use the card as a card of a retail store in the neighborhood.
That is, the retail store side prepares a computer including an information processing unit including a first information processing unit and a second information processing unit, and an observation unit.

Next, the analog chip of the card held by the customer and the number for identifying the card are input to the analog chip DB in the retail store, and more preferably, a registration sticker indicating that the customer has been registered is pasted on the registration sticker pasting column 35. Register as a customer.
Customer management can be performed by the registered analog chip, customer purchase behavior can be stored, and customer services such as issuance of coupons according to the purchase amount can be made possible on the retail store side.

At this time, for example, even if the issuing bank is a card having an IC or the like, an analog chip authentication system unique to each retailer can be constructed independently of the authentication system of the issuer.
In addition, as shown in FIG. 27, a plurality of retail stores 13 (clients) including the first information processing unit 62 are connected to the analog chip management center 12 (authentication server) including the second information processing unit 90. Also, it is possible to construct an authenticity determination system in which the encoding method data (a) and the observation means data (A) are different for each retail store (client).
In other words, the owner of the analog chip card owns one analog chip card 30 so that the retailer independently establishes an authenticity determination system, an authenticity determination system that uses a network system that authenticates the analog chip with an authentication server, etc. It is possible to access a plurality of analog chip authentication systems.

  As a result, analog chip card owners can now receive benefits such as coupons issued by many retailers that could not be received without carrying many membership cards with a single analog chip card. Unprecedented effects can be obtained.

Further, in this embodiment, the measurement point 8 is the corner of the analog chip, but a symbol having the same function as the cut-out symbol used when reading the two-dimensional barcode is provided at a predetermined specific position. The position of the object to be analyzed may be estimated.
Moreover, the observation part of this invention should just be provided with the at least 1 observation method, but may be provided with the several observation method.

In addition, since the analog chip of the present invention is a thing, it is possible to construct different authentication systems by changing the accuracy of the observation method. This will be described as an example of the effect.
For example, when the magnification of the observation unit lens is 10 × when the observation unit lens has the same magnification, the detailed feature of the portion of the object cannot be observed. In addition, it is possible to observe the detailed characteristics of the portion of the object to be analyzed and store it as an analog chip element.
For example, even if the same analog chip is authenticated, an authentication system is constructed that is inexpensive but has a low recognition accuracy to eliminate duplication of the analog chip. This brings about the effect that it is possible to decide, as necessary, whether or not to construct an authentication system with high recognition accuracy for eliminating.

  In other words, even if the value of the result obtained by authenticity determination of an analog chip is high or low, it is now possible to handle certified objects with the same analog chip by multiple observation methods. The effect which is not in the ID card up to can be obtained. As a result, the authenticity determination system of the present invention is a credit card that has a high value obtained when authenticated from an authenticity determination system such as a point card that is relatively inexpensive when obtained by authenticating with a single authenticated object. Therefore, it is possible to provide a certified product that can meet various security level requirements that can be adopted in an authenticity determination system such as the above, and an authenticity determination system.

  The present invention relates to property authentication in personal authentication, can be adopted as personal authentication for credit cards and IC cards, cannot be skimmed and difficult to forge, and even if data is copied in an information network or the like, an analysis method, And by changing the encoding method, it is possible to counter malicious parties, and even if there is fraud, it can be handled by an individual information processing system without discarding the card, thus reducing the security cost of the entire system It can be used for various systems such as coin locker key systems, bicycle parking key systems, emergency personal registration card systems, etc. The availability is extremely large.
