  Since the detection system using the electrostatic capacitance as described above detects the conductive portion in contact with the touch panel, the arrangement of the conductive portion can be reproduced by the position where the finger is placed. The detection accuracy of the conductive portion and the certainty of recognition vary depending on how the conductor is formed, the performance of the capacitance panel, the algorithm of the recognition program, the operation method by the user, and the like. Furthermore, apart from cases where the number of combinations of arrangements is few, such as when there are few combinations, several thousand to several hundreds of thousands of combinations are provided depending on the arrangement of the conductive parts, and there is a high possibility of being accompanied by poor readings and erroneous recognition Become. And in order to ensure the reliability of the code information formed by arrangement | positioning of an electroconductive part, the fall of the possibility of the above potential misrecognition is indispensable.

  Also, a credit card is often used for various payments. The identification information possessed by the credit card is a card number stamped on the card surface, and is also recorded on a magnetic stripe or a built-in IC chip. When it is necessary to confirm that such a credit card is not a counterfeit product or has a credit card by Internet shopping or Internet banking, the card number recorded on the magnetic stripe or the like is acquired. However, a dedicated card reader is required to obtain the card number from the magnetic stripe.

  The present invention has been invented in view of the circumstances, and provides a unique data carrier such as a card to which code information that can be recognized by an electronic device having a touch panel is provided, and uses a card reader or the like from the data carrier. It is an object of the present invention to provide means for acquiring code information and the like and improving the reliability of the acquired information.

In order to solve the above problems, the present invention has the following configuration. That is,
In an electronic device equipped with a capacitance detection type touch panel, an authentication program for authenticating a data carrier having a plurality of conductive parts,
Code information generated based on the arrangement position information of the conductive part detected by the capacitance detection touch panel or the arrangement position information;
Enter collation information consisting of letters, numbers, symbols and graphic information that can be earned through visual or optical recognition means, or a combination of these,
The data carrier is authenticated when the code information and the verification information correspond to each other.

Moreover, in order to solve the said subject, this invention has the following structures. That is, a data carrier authentication system,
An authentication program executed in an electronic device equipped with a capacitance detection type touch panel, and a data carrier having a plurality of conductive parts detectable by the capacitance detection type touch panel,
The data carrier is provided with collation information consisting of letters, numbers, symbols and graphic information that can be obtained through visual or optical recognition means, or a combination thereof,
The authentication program is:
Generate code information based on the arrangement position information of the conductive part detected by the capacitance detection type touch panel or the arrangement position information,
The data carrier is authenticated when the collation information corresponds to the arrangement position information of the conductive portion or code information generated based on the arrangement position information.

Moreover, in order to solve the said subject, this invention has the following structures. That is,
A data carrier for performing authentication in an electronic device equipped with a capacitance detection touch panel,
A plurality of conductive parts that can be detected by a capacitance-sensitive touch panel;
It is characterized by having collation information consisting of letters, numbers, symbols and graphic information that can be earned through visual or optical recognition means, or a combination thereof.

Moreover, in order to solve the said subject, this invention has the following structures. That is,
A credit card for authentication in an electronic device equipped with a capacitance detection touch panel,
A plurality of conductive parts that can be detected by a capacitance-sensitive touch panel;
It is characterized by having collation information consisting of letters, numbers, symbols and graphic information that can be earned through visual or optical recognition means, or a combination thereof.

The number of pieces of code information generated by the combination of the arrangement of the conductive parts is limited due to the limitation of the area of the capacitance detection type touch panel and the number of conductive parts that can be recognized simultaneously. However, there is virtually no quantitative limitation on the collation information. Therefore, the number of combinations of code information and collation information may be considered to be virtually unlimited. Therefore, by combining the code information and the collation information, there is an effect that a data carrier carrying unique information can be formed without any number limitation.
In addition, there is a possibility that an error may occur in the recognized code information for the reason that the detection of the conductive portion using the capacitance detection type touch panel is insufficient. However, according to the present invention, the code information by the conductive portion and the collation information given by a different method are provided on the data carrier. Since code information and collation information can determine the correspondence between each other, it is possible to determine whether or not the acquired code information is correct, and the reliability of the data carrier can be maximized. It has the effect.

It is a correspondence table showing an example of a data table.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a schematic diagram showing the structure of a card-type data carrier 1. As an example, the data carrier 1 is formed by superposing two pieces of paper 2a and 2b as a single card. A plurality of conductive portions 3 (3a, 3b, 3c, 3d, 3e) formed of metal foil, conductive ink or the like are provided between the two pieces of paper 2a, 2b. Of course, the number of the conductive portions 3 is not limited to five, and there are various modes ranging from one to five or more depending on the specifications of the applied electronic device.
When the conductive portion 3 is formed of a metal foil, conductive ink, or the like, these can be formed in the printing process on the paper, so that the data carrier 1 can be formed very inexpensively. Needless to say, the method of forming the conductive portion 3 is not limited to metal foil and conductive ink.

When the paper piece 2a is overlapped and brought into close contact with the paper piece 2b on which the conductive portion 3 is formed, a single card as shown in FIG. 1B in which the conductive portion 3 is arranged at a predetermined position is formed. In this example, the arrangement of the conductive portion 3 is concealed in appearance, and the arrangement of the conductive portion 3 cannot be known unless the data carrier 1 is destroyed.
Depending on the application of the data carrier 1, the arrangement of the conductive portion 3 may be permitted even if it is not concealed in appearance. In this case, the conductive portion 3 may be formed directly on the front or back surface of a single piece of paper or resin sheet piece as a mount, and a thin protective coating layer is provided to prevent wear of the conductive portion 3 as necessary. .

Further, display information 4 using visually recognizable characters, numbers, other symbols, and the like is provided on the front surface or the back surface of the data carrier 1. For example, the display information 4 includes information that can be input via an input keyboard (including a software keyboard) of an electronic device. This is collation information used when the data carrier 1 is recognized by the electronic device. When the data carrier 1 is used as a credit card, the card number 23 shown in FIG. May be.
Note that the collation information is not necessarily information that can be input via the keyboard. For example, a part or all of the data carrier 1 may be photographed by the camera function, and the photographed video may be used as the collation information. .
As an example, the user's own face photograph may be used as the collation information. In this case, since the user and the data carrier 1 can be associated with each other, the data carrier 1 can be used as a means for personal authentication, and a method such as use when paying for the purchase of goods or services can be used. Become. The above is the outline of the data carrier 1 formed in a card shape.

FIG. 2 shows a state in which the data carrier 1 is superimposed on a smartphone 6 having a touch-type capacitance panel 5 as an example of an electronic device. In the smartphone 6, the arrangement position of the conductive portion 3 included in the data carrier 1 is acquired using a recognition program described later, and this is stored as code information included in the data carrier 1. This arrangement position may be based on an area that can be represented by virtually divided coordinates on the capacitance panel, or all the conductive parts 3 acquired regardless of the coordinate position on the capacitance panel. It may be generated based on the positional relationship. If it is not necessary to convert the arrangement position into code information, the arrangement position information itself may be used.
As shown in FIG. 3, the conductive portion 3 is disposed in a region (recognition region) 7 that can face the surface of the capacitance panel 5 of the data carrier 1. For example, as shown in FIG. 4, one or two or more conductive portions 3 are provided at matrix-arrangeable positions where the vertical and horizontal intervals are set equal to each other.

Each explanatory drawing shown in FIG. 4 represents the position where the conductive part 3 provided in the recognition area 7 can be arranged by a number.
FIG. 4A assumes a case where conductive portions 3 having a diameter of 9.5 mm are arranged at 20 locations of 4 rows × 5 columns at 11 mm intervals. Using this arrangement, when five conductive positions 3 are selected from 20 possible arrangement positions, there are several 20C5 = 15,504 combinations of arrangements.
FIG. 4B assumes a case where the conductive portions 3 having a diameter of 7.5 mm are arranged at 30 locations of 5 rows × 6 columns at intervals of 9 mm. Using this arrangement, when five conductive positions 3 are selected from 30 possible arrangement positions, there are several 30C5 = 142,506 combinations of arrangements.
FIG. 4C assumes a case where conductive portions 3 having a diameter of 6 mm are arranged at 30 locations of 5 rows × 6 columns at intervals of 8 mm. Using this arrangement, when five conductive positions 3 are selected from 30 possible arrangement positions, there are several 35C5 = 324,632 combinations of arrangements.

Moreover, although the above example shows the number of combinations in which five are selected from the possible positions, any number such as one, two, three or more can be set. Even if the format of the arrangementable positions is the same, different unique arrangement position information can be formed by changing the number of selections.
Further, the positions at which the conductive portions 3 can be arranged do not have to be in an equally spaced matrix. Furthermore, as long as adjacent conductive portions do not overlap, conductive portions having a diameter exceeding the arrangement pitch interval may be provided. In this case, it is allowed to dispose conductive portions having different sizes in the recognition region 7.
Further, as long as collation by the recognition application is possible, any arrangement may be used as long as the arrangement of the conductive portions can be specified without seemingly having a regular arrangement rather than a lattice arrangement.

FIG. 5 is an example in which the conductive portions 3 are arranged at the above-described positions where the arrangement is possible, and shows an arrangement when viewed from the capacitance panel 5 side. Actually, it is hidden and cannot be seen.
FIG. 5A shows an example in which the conductive portions 3 are provided at four locations (1st, 6th, 9th, 18th) arbitrarily selected from 20 possible positions. When this is an encoded character string, it can be expressed as (10000 01001 00000 00010). Since there are 4,845 unique combinations for selecting 4 locations from 20 locations, there are 4,845 possible combinations that can be encoded as character strings as described above.

FIG. 5B shows an example in which the conductive portions 3 are provided at five locations (No. 2, No. 12, No. 14, No. 17, No. 27) arbitrarily selected from 30 possible positions. If this is an encoded character string, it can be expressed as (010000 000000 101001 000100). Since there are 142,506 unique combinations for selecting five from thirty locations as described above, there are 142,506 combinations that can be encoded as character strings as described above.
FIG. 5C shows an example in which the conductive portions 3 are provided at five locations (4th, 8th, 20th, 24th, and 28th) arbitrarily selected from 35 possible positions. When this is converted into an encoded character string, it can be expressed as (0000100 0100000 0000001 0001000 1000000). As described above, there are 324,632 unique combinations for selecting five from the 35 locations, so that there are 324,632 possible combinations that can be encoded as a character string as described above.

As described above, hundreds of thousands of unique codes can be generated depending on the arrangement of the conductive portion 3, but this number depends on the size of the card and the performance of the capacitance panel. The number of combinations is finite. Next, means for extending the number of unique data carriers that can be generated by the arrangement of the conductive parts to almost infinite will be described.
This means is equipped with separate information (collation information) that can be obtained visually on the data carrier or by a method other than the detection method of the conductive part, and collates the collation information with the detection result of the conductive part. It can be realized by. There are several methods for this, and will be described in detail below.

First Method The first method is a method in which a character string that can be input by a keyboard such as letters, numbers, symbols, etc. is placed on a data carrier, and the character string is made to correspond to a combination formed by the arrangement of the conductive portions 3. It is. A simple example of this correspondence method is a method of forming a correspondence table as shown in FIG. In this specification, this is called a data table.

The correspondence table shown in FIG. 8 shows an example using the arrangement of the conductive parts shown in FIG. 4A as an example. In the case of this arrangement, the total number of combination codes by arrangement is 15,504 as described above. The left column of this correspondence table is a simple serial number corresponding to the combination of codes, and indicates that this combination exists from No. 1 to No. 15,504.
The “combination code by arrangement” in the second column from the left represents the relationship between the arrangement position and presence / absence of the conductive parts in a 1/0 sequence such as a binary number. In the case of this example, the head corresponds to position 0 shown in FIG. 4A and the tail corresponds to position 19 shown in FIG. 4A.

The third column from the left is a five-digit character (number) sequence corresponding to “combination codes by arrangement” from No. 1 to No. 15504. If each digit of 5 digits is expressed using a number from 0 to 9, 10 5 = 100,000 combinations can be made, and one character (number) is assigned to one “combination code by array”. ) Column can be provided as corresponding collation information.
That is, the first (00000 00000 00000 11111) corresponds to the collation information [00001] in a one-to-one relationship, and when the combination code by the array is (00000 00000 00000 11111), the collation information [ 00001] is determined, and when the collation information is [00001], the combination code (00000 00000 00000 11111) based on the array is uniquely determined. The data table storing this correspondence relationship is held by an application program installed in an electronic device as a recognition program or stored in a server on the Internet for use.

Specifically, after obtaining the arrangement position information of the conductive portion included in the data carrier or the code information based on the arrangement position information via the capacitance panel, the collation information displayed on the data carrier is, for example, a keyboard. (Including software keyboard). By comparing the information acquired via the capacitance panel and the collation information using the data table, it is possible to determine whether the arrangement position information is correct. If the information read via the capacitive panel matches the input information, the read information is correct and the maximum certainty that the information is obtained from a legitimate data carrier is guaranteed. Is done.
On the other hand, if the information read through the capacitance panel and the input information do not correspond in the comparison on the data table, the read information is incorrect. In this case, it is assumed that the data carrier is not an authentic product, is damaged, or has not been properly read by an insufficient operation method.
As described above, only when the information read through the capacitance panel is correct, the data carrier can be authenticated as a normal one and the subsequent processing can be continued.

Further, the fourth column and the fifth column from the left of the correspondence table shown in FIG. 8 correspond to the “combination codes by arrangement” from No. 1 to No. 15504, and are different from those shown in the third column. A 5-digit character (number) string is associated. The 5-digit character (numeric) string to be corresponded in this way does not have to be regular, and may be given by random number generation processing.
In this way, one authentication result is obtained by matching the “combination code by array” from No. 1 to No. 15504 with one of 105 numbers composed of, for example, five digits. . As described above, when 15504 types of data carriers are used, the same usage as that of 15504 × 105 types of data carriers is possible. In addition, the collation information corresponding to the “combination code by arrangement” is not limited to numbers, and characters and symbols can be used, and the number of digits can be set freely. Therefore, even when overlapping use of the “combination code by arrangement” is recognized, the number of pieces of collation information is substantially infinite, which is similar to the case where there are nearly infinite types of data carriers. In this way, by making correspondence with the collation information, it becomes possible to generate countless data carriers having unique identification (unique).

Second Method The second method is a method of associating “combination code by array” with collation information without using a data table.
As described above, a data carrier having “combination codes by arrangement” from No. 1 to No. 15504 using the arrangement of the conductive parts shown in FIG. 4A will be described as an example. Also in this example, after reading the arrangement of the conductive portion of the data carrier via the capacitance panel, the collation information displayed on the data carrier is input by a keyboard (including a software keyboard). As a result, it is possible to determine whether or not the information acquired via the capacitance panel is acquired correctly.
For this determination, various encryption algorithms or a conversion program that performs processing similar to the encryption algorithm is used. When the information acquired via the conversion program and the capacitance panel is (00000 00000 00000 11111), the information is converted and, for example, collation information [00001] displayed on the data carrier is output. Conversion program. This conversion program is black boxed and its processing algorithm is completely secret.

The conversion program that generates collation information from the above-described “combination code by array” can generate different collation information from the same “combination code by array” by changing internal variables. In other words, in the above example, a plurality of sets of unique collation information corresponding to the “combination codes by array” from No. 1 to No. 15504 can be generated by setting variables in the conversion program. It can be done. Therefore, simply by setting variables inside the conversion program, the number of unique data carriers that can be distinguished from other data carriers can be generated so that the combination with the collation information is virtually unlimited. It can be used in the same way as it exists.
For this, for example, a hash function may be used. The hash function is a function that generates specific information corresponding to the input of unique information, and generates information from which the original information cannot be obtained from the generated specific information. is there.

  A simple example of a conversion program that generates collation information from a “combination code by array” will be described. For example, when the “combination code by array” is (10000 00001 00000 01110), there are four blocks of codes consisting of 1 or 0. When the first block and the second block, and the third block and the fourth block are interchanged, (00001 10000 01110 00000) is obtained. Converting this to decimal as a continuous binary number gives 49600. For example, a numerical value of 5 to 6 digits can be acquired by such an algorithm, and this is used as collation information. This verification information is provided on the data carrier in a form that can be visually recognized by printing, stamping, or other means.

In actual use, after a dedicated application program is started, the setting is made so as to require input of collation information printed on the data carrier shown in FIG. 6A. In FIG. 6A, 10 is a message displayed after the application is started, and displays usage, precautions, operation instructions, and the like as necessary. Reference numeral 11 denotes a display unit for numerical values inputted as collation information, and reference numeral 12 denotes a software keyboard for inputting collation information. Information displayed on the device carrier 1 is input using the software keyboard 12, and a confirmation button (not shown) is operated to complete the input of collation information.
In this process, for example, when 49600 generated in the above example is input as collation information, numerical values are binarized in the reverse order to the process described above (00001 10000 01110 00000). Then, the first, second, third, and fourth blocks are replaced to obtain (10000 0000100000 01110). That is, the “combination code by arrangement” is uniquely determined from the collation information.

When the verification information is input, the guide 13 representing the contact position of the card 1 formed as the data carrier shown in FIG. 6B is displayed. When the card 1 is placed on the capacitance panel 5 along the guide 13, the conductive part is detected and a combination code based on the arrangement is obtained. If the information generated from the verification information and the “combination code by arrangement” obtained by bringing the data carrier close to the capacitance panel match, it is assumed that the reading has been performed normally, and the payment for the product purchase is made. And allow processing to continue, such as viewing and purchasing content. Further, if the collation results do not match, it is impossible to continue the subsequent processing because there is some trouble such as whether the input is illegal or the data carrier is damaged.
In this verification process, by obtaining a code from the detected arrangement of the conductive parts, a numerical value that can be compared with the verification information is obtained by the above-described procedure, and this and the verification input using the software keyboard 12 are performed. Both may be collated by comparing with information, and either method may be adopted.

Examples of use of data carrier As described above, the data carrier can be used for payment or for personal authentication. As an example, it can also be configured as a credit card.
FIG. 7A is an explanatory diagram of a credit card 20 equipped with a function as a data carrier, and is a state where it is disassembled into a first layer 20a constituting the surface layer portion and a second layer 20b constituting the back side layer for explanation. Is shown. FIG. 7B shows an external perspective view of the credit card 20 configured as described above. FIG. 7C shows a state in which the credit card 20 having the above configuration is arranged on the capacitance panel.

  The credit card 20 is a rectangular card made of resin using a PET material, and includes a magnetic stripe 21 and an IC 22 in the same manner as a general card currently in circulation. The IC 22 is optional and may be omitted if it is not necessary depending on the required safety. On the surface, card number 23, name 24, hologram 25 formed of metal foil, and other information are displayed by printing or stamping. These have the same configuration as a general credit card. In addition, in a general credit card, a security code which is a number of digits apart from the card number 23 is printed on the front surface or the back surface. A security code 26 is also printed on the credit card 20 according to the present embodiment.

  In the case of the credit card 20 according to the present embodiment, a plurality of conductive portions 27 (27a, 27b, 27c, 27d, 27e) having a size recognizable by the capacitance panel are provided inside or on the back surface. The five conductive portions 27 are conductive portions whose arrangement can be recognized by a capacitive touch panel in the same manner as the conductive portion 3 described above, and are formed of conductive metal foil. The conductive portion 27 is disposed at a predetermined position selected from the dispositionable positions set at intervals of 8 mm. This arrangement possible position is related with the security code 26 as an example. The association method is the above-described data table collation method, function method, or other method, and the code constituted by the arrangement of the conductive portion 27 is uniquely determined by the security code 26.

  Note that a hologram 25 is a characteristic of a general credit card. Since the hologram is a thin film made of metal, it can be considered that the recognition or the recognition of the conductive portion 27 is affected by the capacitive touch panel in the same manner as the conductive portion 27 formed of the metal foil. Note that this varies depending on the thickness of the credit card. If the thickness of the credit card is large, the distance from the capacitive touch panel is increased and the influence on the detection of the conductive portion 27 is reduced. On the other hand, if the thickness of the credit card is small, capacitive coupling is made between the capacitive touch panel and detection of the conductive portion 27 may be hindered. For this reason, in this embodiment, the position where the hologram 25 is disposed and the position where the conductive portion 27 is disposed do not overlap with each other. For this reason, in this example, the shape of the region for setting the position where arrangement is possible is not rectangular.

In the case of the example shown in FIG. 7, the disposition position is not a complete rectangle but a concave shape. This indicates that the outer shape of the entire area does not necessarily have to be a rectangle although the matrix has possible arrangement positions. This means that the shape may be intentional regardless of the presence of the hologram 25 or other obstacles.
Therefore, even if the arrangement position is expressed in binary notation as (10000 01001 00000 00010), the actual position of the conductive part to be arranged is not absolute in all cases. The external shape as the entire area of the arrangement possible position can be changed depending on the way of setting the coordinates.

The credit card having the above-described configuration formed as a data carrier can detect the conductive portion 27 by making it face the surface of the capacitance panel 5 of the smartphone 6 as shown in FIG.
Then, by inputting a numerical value printed as the security code 26 before or after detection of the conductive portion 27 as verification information, the code read by the capacitance panel 5 (arrangement of the conductive portion 27) and verification information And verifying whether the credit card is genuine or counterfeit or whether the code has been read correctly.

  The above-described structure may be applied to credit cards of companies that are currently distributed in the market, or may be manufactured and provided at a low cost as a simple credit card for low-value payment such as a prepaid card. The advantage of this data carrier is that when purchasing a product or content using a smartphone, the data carrier itself used for purchase must be used. For example, a card number may be stolen due to skimming, etc., but if you build a system that can not be settled if there is no real credit card (data carrier) at the time of payment, even if you know only the card number Can not be used. Even when such a system is constructed, a separate hardware means such as a card reader for confirming the presence of the data carrier is not necessary. The payment system using the data carrier according to the present embodiment has an effect that a reliable payment system or the like can be constructed at low cost by providing an authentication and recognition program for the data carrier and the data carrier. Yes.

  As described above, as an example of the method according to the present invention, an example has been described in which collation information is visually recognized and input using a keyboard or the like. However, the collation information is not limited to this example, and may be information such that a barcode or a rectangular pattern code is recognized by the camera function. Further, as described above, any information that can be compared, such as a face photograph of a user, a moving image, or a voice, may be used. In addition, although a dedicated reader is required, the magnetic information recorded on the magnetic stripe, such as that possessed by a credit card, can be used as verification information.

Further, the data carrier authentication system, the data carrier authentication method, the data carrier, and the credit card described above all explain the case where a recognition program for recognizing the data carrier is installed in an electronic device and executed.
However, the authentication program may be executed on a server connected via the Internet. In this case, the electronic device acquires the coordinates of the conductive portion mounted on the data carrier and transmits it to the server, and performs subsequent event processing according to the authentication result of the transmitted coordinates. The server generates code information based on the coordinates acquired from the electronic device, and compares this with a data table held by the server to authenticate the data carrier.

In the above case, as a program to be executed on the electronic device, for example, a program described in a Script language installed in an html file that can be viewed on a Web browser is used. In the Script language, since the source code is disclosed to the user of the electronic device, it is impossible to perform all the authentication processing in the Script language because of a safety problem. For this reason, only acquisition of the coordinates of the data carrier is performed by a program in the Script language described in the html file, and coordinate code conversion and authentication processing are performed on a server that the user cannot know.

The authentication system using the Web browser as described above does not require the user to download dedicated application software. In other words, the browsing screen can be used as a data carrier authentication screen simply by browsing a site on the Internet having this authentication system. When downloading application software, the user is accompanied by considerable psychological resistance. On the other hand, when viewing html files provided on the Internet, such psychological resistance is quite small. Providing the present invention in a form using a Web browser can be said to be an important means for the convenience of the user.

Further, the authentication program executed on the server may be configured using a hash function that generates authentication information based on the code information. In this case as well, the coordinates of the conductive part mounted on the data carrier are acquired and transmitted to the server by a script language program using a Web browser as described above. Also, authentication information posted on a data carrier such as a printed number is input by the user and transmitted to the server.
The authentication program installed in the server generates code information from the coordinates acquired by the touch panel, and generates authentication information based on the coordinates or code information.
