Description

The present invention relates to an age identification recognition system, and in particular, the age of the customer is applied to vending machines that have age restrictions for purchasing cigarettes, alcoholic beverages, adult magazines, DVDs, etc., and entrance doors to facilities that have age restrictions. This invention relates to an age identification recognition system for automatically controlling and operating the system.

Recently, a product vending system using a special card has been known as a system for confirming the age and operating the vending machine. In this system, after inserting the necessary coins and pressing the select button for the desired product, the device operates and the product is released by touching the recognition unit with a special card. This special card is restricted to individuals and cannot be lent.

Currently, in addition to using this special card, there is also a system in place that allows you to purchase products by inserting your driver's license into the reading slot and having your age read.

Here, in order to obtain the above-mentioned dedicated card, special procedures are required and complicated, and there are many cases where even purchasers who have cleared the legal age do not own the card.

On the other hand, driver's licenses have already been digitized and many people have obtained them. In addition, citizens can receive a personal number card (My Number Card), which is also an electronic card, and electronic certificate cards that can confirm age are becoming popular in addition to cards dedicated to purchasing specific products. are doing.

Consider the case of unattended age verification at vending machines, etc.
Currently, RFID type IC cards having an RFID (radio frequency identifier, hereinafter the same) are used for driver's licenses, personal number cards, etc.
However, since the information stored in the IC that determines the age such as date of birth is personal information, it is stored in an area protected by a verification number (PIN code) in the RFID IC.
If the system requires the user to enter a verification number (PIN code) into a machine such as a vending machine, the purchasing procedure is complicated and inconvenient for the user. This makes it difficult to promote use.
Information that should be entered as a verification number is written on the face of the personal number card, so if this is read optically and the system automatically inputs it on behalf of the user, it is possible to enter an incorrect verification number. , there is a risk that the card will be locked, causing inconvenience to the user and making it difficult to promote usage.
On the other hand, if the age is authenticated only by the date of birth written on the face of the card, there is a high risk that the card will be used fraudulently with a simple counterfeit card, and the certainty of the user's age is too low.

The present invention has been made in view of the above-mentioned problems in the prior art, and is an electronic certificate with RFID used as a means to confirm age when age confirmation is required when purchasing products or entering facilities. An object of the present invention is to ensure the authenticity of a user's electronic certificate card and the certainty of his or her age without causing any inconvenience to the user in an age identification recognition system using a digital certificate card.

An age identification and recognition system according to one aspect of the present invention is an age identification and recognition system that can handle multiple types of electronic certificate cards when identifying an age based on an electronic certificate card having an RFID. , an RFID reading unit capable of communicating with the RFID of the electronic certificate card; an image sensor unit that captures the face of the electronic certificate card as an image; and written on the face of the electronic certificate card captured by the image sensor unit. an optical character recognition unit that recognizes the characters that are displayed, and a control unit, the control unit receiving an instruction to select an application ID assigned to an application installed for each type of the plurality of electronic certificate cards. the electronic certificate card via the RFID reading unit, and when the RFID reading unit receives the result that the application ID has been selected, the electronic certificate card transmits the electronic certificate corresponding to the application ID. The RFID reading unit attempts to read out information stored in the RFID that can be read without a verification number for the identified electronic certificate card type. However, if expiration date data is included in the information that can be read without a reference number for the identified type of electronic certificate card, the electronic certificate card is determined to be valid based on the expiration date data obtained through the trial. It is determined whether or not the expiration date has expired , and if the expiration date data is not included in the information that can be read without a verification number for the specified type of electronic certificate card, the optical character recognition unit The expiration date section in which the expiration date is written is specified from the format of the face of the specified electronic certificate card type, and the expiration date written in the expiration date part of the face of the electronic certificate card is read. The electronic certificate card is configured to specify the expiration date of the electronic certificate card, and to determine whether or not the electronic certificate card is within the expiration date based on the specified expiration date of the electronic certificate card.

According to the present invention, when age verification is required when purchasing products or entering facilities, etc., in an age identification and recognition system that uses an electronic certificate card with RFID as a means for verifying the age, the user The authenticity of the user's electronic certificate card and the accuracy of the user's age can be ensured without the inconvenience of having to enter a verification number.

An embodiment of the present invention will be described below with reference to the drawings. The following is one embodiment of the present invention and is not intended to limit the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described with reference to the drawings, taking as an example a case where a cigarette vending machine is installed. FIG. 1 is a block diagram of the age identification section, and FIGS. 2 and 3 are flowcharts showing the operating procedure of the system according to the present invention.

The age identification unit has a mechanism for loading and ejecting cards, and the card used here is an electronic certificate card with RFID, and accepts three types of cards that correspond to ISO-14443 Type-B. For example, the three types are a personal number card (my number card), a driver's license, and a residence card.

As shown in FIG. 1, the age identification section has a card reading device 5 for an electronic certificate card drawn in by the above-described loading mechanism. This card reading device 5 has a CPU section 6, which includes a card transport section 7, an optical sensor section 8, a display section 9, an image sensor section 10, and electronic information contained in the inside (IC) of the electronic certificate card. It has a structure in which an RFID reader 11 for reading information and a buzzer 12 are connected, and can also be connected to a PIN pad (a small keyboard for entering a verification number, i.e., a PIN code, to confirm the identity of the person) 13. It becomes. Note that since the PIN pad 13 is not used in implementing the present invention, the present invention can be implemented even with a card reading device that does not have a structure that allows connection to the PIN pad 13. Further, the buzzer 12 may be any sound reproducing unit, such as a speaker or the like.

The control section in this embodiment is constituted by the CPU section 6.
Further, an optical character recognition unit (Optical Character Recognition) that recognizes characters written on the face of the electronic certificate card captured by the image sensor unit 10 functions by executing software in the CPU unit 6. Furthermore, the CPU section 6 executes age identification and authentication processing, which will be described below, and outputs a card determination signal (OK or NG) to the control unit of the external device. Among the card determination signals (OK determination (S28) or NG determination (S50)), the OK determination (S28) corresponds to age authentication in this system. In the example of this embodiment, age authentication is authentication of being 20 years old or older.
The control unit of the external device controls the external device and causes it to perform an operation (providing a product).

The procedure for age identification and recognition by the age identification and recognition system configured as described above will be explained with reference to FIGS. 2 and 3.
(1) Introduction First, when purchasing a product from a vending machine or the like, a user inserts the electronic certificate card to be used into the age identification section.
When the electronic certificate card is inserted (S11), the CPU unit 6 controls to automatically transport the electronic certificate card and capture the image of the face of the electronic certificate card by the image sensor unit 10 (S12).

Next, the CPU section 6 instructs the RFID reading section 11 to issue request B (S13). Here, request B is an instruction to respond if the card is an ISO-14443 Type-B card. The RFID reader 11 emits radio waves to search for an ISO-14443 Type-B card nearby. If there is an ISO-14443 Type-B IC card in the card reading device 5, the IC card returns a response to the RFID reading unit 11 saying "It is an ISO-14443 Type-B card." Here, it is assumed that the same response is returned from the inserted electronic certificate card and the RFID reading unit 11 reports the response to the CPU unit 6 (OK in S14). In addition, in the case of NG in step S14, the card is ejected (S15, S16)

Next, the CPU section 6 transmits a selection command for the application ID of the personal number card to the electronic certificate card via the RFID reading section 11 (S17). The application ID is identification information assigned to a plurality of applications installed for each card type.
Here, the application configurations of the three types of cards (personal number card, driver's license, and residence card) handled in this embodiment will be explained.
FIG. 4 is a conceptual diagram showing the application configuration within the IC chip of the personal number card. FIG. 5 is a conceptual diagram showing the application configuration within the IC chip of a driver's license.
FIG. 6 is a conceptual diagram showing the application configuration in the IC chip of the residence card.
The IC chip of the personal number card contains applications AP1 to AP6 and the card OS. In this embodiment, the application ID of the ticket information confirmation application AP2 is used in step S17. The ticket face item confirmation application AP2 includes information that can be read without a verification number and information that can be read with a verification number (see FIG. 7).

(2) In the case of a personal number card The selection result of the application ID of the personal number card is returned to the CPU section 6 from the electronic certificate card via the RFID reading section 11 (OK in S18).
Next, the CPU unit 6 attempts to read the issuing municipality code, which can be read without a verification number, from the electronic certificate card via the RFID reading unit 11 (first step S19).
If the reading is successful (OK in S20), the CPU section 6 determines whether the issuing municipal code is 5 digits or not (S21).
If it is OK in step S21, the CPU unit 6 executes pasting detection determination (S22). The pasting detection determination is a third step in which it is determined whether pasting is forged or not based on the image of the electronic certificate card (S12) captured by the image sensor section 10.

If it is OK in step S22, the CPU unit 6 reads the date of birth and expiration date in the image of the face of the electronic certificate card scanned in step S12 using the optical character recognition unit (S23, second step). Here, the CPU unit 6 confirms that the inserted card is an individual number card based on the OK result in step S18, so the date of birth is determined based on the format of the face of the individual number card. and the expiration date section in which the organic expiration year is written are identified and subjected to OCR processing by the optical character recognition section. In this way, before the second step, the control unit 6 specifies the card type of the electronic certificate card through communication via the RFID reading unit 11, up to the classification that allows identification of the date of birth written on the face of the card. In the second step, the part where the date of birth is written on the face of the electronic certificate card is identified and the date of birth information is read. Here, the expiration date year is also processed in the same way. This allows the date of birth and expiration date to be read with high efficiency and precision.
Next, the CPU unit 6 calculates the age from the date of birth information read from the date of birth field in step S23 (S24). Note that the age calculation is performed by the CPU section 6 referring to the current year, month, and day (referring to the internal calendar), and calculating the current age from comparison with this.

Next, the CPU section 6 performs age determination. Here, it is determined whether the person is over 20 years old (S25).
If it is OK in step S25, that is, the person is 20 years of age or older, the CPU section 6 calculates the expiration date from the expiration year and date of birth written on the face of the ticket read by the optical character recognition section in step S23. , and compares it with the internal calendar to determine whether or not it is within the expiration date (fourth step (S26, S27)).
If it is within the expiration date (OK in S27), an OK determination is output to the control unit of the external device (S28), and the electronic certificate card is ejected (S29).

(NG processing)
When the CPU section 6 is NG in steps S20, 21, 22, 25, and 27, it outputs the NG determination to the control unit of the external device (S50) and ejects the card (S51).

(3) When it is a driver's license If the result in step S18 is NG, the CPU section 6 transmits a selection command for the application ID of the driver's license to the electronic certificate card via the RFID reading section 11 (S30).
The IC chip of the driver's license contains applications and card OS for BP10 (BP11, BP12, BP13) and BP20 (see FIG. 5). In this embodiment, the application ID of "dedicated file 1" BP11 is used in step S30. The "master file" BP10 includes information that can be read without a reference number and information that can be read with a reference number (see FIG. 7).
The selection result of the application ID of the driver's license is returned to the CPU section 6 from the electronic certificate card via the RFID reading section 11 (OK at S31).
Next, the CPU unit 6 attempts to read expiration date data that can be read without a verification number from the electronic certificate card via the RFID reading unit 11 (first step S32).
If the reading is successful (OK in S33), the CPU unit 6 executes pasting detection determination (S34). Again, the pasting detection determination is the third step of determining whether or not pasting is forged based on the image of the electronic certificate card captured by the image sensor unit 10 (S12).

If OK in step S34, the CPU unit 6 reads the date of birth part of the image of the face of the electronic certificate card scanned in step S12 using the optical character recognition unit (second step S35). Here, the CPU unit 6 confirms that the inserted card is a driver's license based on the OK result in step S31, so the date of birth is determined based on the format of the driver's license. The text is specified and subjected to OCR processing by an optical character recognition unit. In this way, before the second step, the control unit 6 specifies the card type of the electronic certificate card through communication via the RFID reading unit 11, up to the classification that allows identification of the date of birth written on the face of the card. In the second step, the part where the date of birth is written on the face of the electronic certificate card is identified and the date of birth information is read. This allows the date of birth to be read with high efficiency and accuracy.
Next, the CPU unit 6 calculates the age from the date of birth information read from the date of birth field in step S35 (S36).

Next, the CPU section 6 performs age determination. Here, it is determined whether the person is over 20 years old (S37).
If it is OK in step S37, that is, the person is 20 years of age or older, the CPU unit 6 compares the expiration date data read from the IC chip with the internal calendar, and determines whether or not the expiration date is within the expiration date (fourth step ( S38, S39)).
If it is within the expiration date (OK in S39), an OK determination is output to the control unit of the external device (S28), and the electronic certificate card is ejected (S29).

(NG processing)
When the CPU section 6 is NG in steps S33, 34, 37, and 39, it outputs the NG determination to the control unit of the external device (S50) and ejects the card (S51).

(4) In the case of a residence card If the result in step S31 is NG, the CPU section 6 transmits a selection command for the application ID of the residence card to the electronic certificate card via the RFID reading section 11 (S40).
The IC chip of the residence card contains applications of the CP10 (CP11, CP12, CP13) and CP20 and the card OS (see FIG. 6). In this embodiment, the application ID of "dedicated file 1" CP11 is used in step S40. The "master file" CP10 includes information that can be read without a reference number and information that can be read with a reference number (see FIG. 7).
The selection result of the application ID of the residence card is returned to the CPU section 6 from the electronic certificate card via the RFID reading section 11 (OK at S41).
Next, the CPU unit 6 attempts to read card type data that can be read without a verification number from the electronic certificate card via the RFID reading unit 11 (first step S42). Regarding the residence card, it is not a dedicated card and can be read without a reference number.If "A" can be read as card type data, it is identified as a residence card. Therefore, here, an attempt is made to see if "A" can be read as the card type data. In addition, if it is "B", it is a special permanent resident certificate.
If "A" is successfully read (OK in S43), the CPU unit 6 executes pasting detection determination (S44). Again, the pasting detection determination is the third step of determining whether or not pasting is forged based on the image of the electronic certificate card captured by the image sensor unit 10 (S12).

If OK in step S44, the CPU section 6 reads the date of birth and expiration date section of the image of the face of the electronic certificate card scanned in step S12 using the optical character recognition section (second step S45). Here, the CPU unit 6 confirms that the inserted card is a residence card based on the OK result in step S43, so the date of birth section in which the date of birth is written is determined based on the format of the face of the residence card. , the expiration date section in which the expiration date (year, month, and day) is written is identified and subjected to OCR processing by the optical character recognition unit. In this way, before the second step, the control unit 6 specifies the card type of the electronic certificate card through communication via the RFID reading unit 11, up to the classification that allows identification of the date of birth written on the face of the card. In the second step, the part where the date of birth is written on the face of the electronic certificate card is identified and the date of birth information is read. Here, the expiration date is also processed in the same way. Thereby, the date of birth and expiration date can be read with high efficiency and accuracy.
Next, the CPU unit 6 calculates the age from the date of birth information read from the date of birth field in step S45 (S46).

Next, the CPU section 6 performs age determination. Here, it is determined whether the person is over 20 years old (S47).
If it is OK in step S47, that is, the person is 20 years of age or older, the CPU unit 6 compares the expiration date data written on the face of the ticket read by the optical character recognition unit in step S45 with the internal calendar, and determines whether the expiration date is within the date. It is determined whether or not (fourth step (S48, S49)).
If it is within the expiration date (OK in S49), an OK determination is output to the control unit of the external device (S28), and the electronic certificate card is ejected (S29).

(NG processing)
When the CPU section 6 is NG in steps S41, 43, 44, 47, and 49, it outputs the NG determination to the control unit of the external device (S50) and ejects the card (S51).

[Other effects]
As described above, age authentication (OK determination S28) based on the date of birth information read by the optical character recognition unit in the second step is output only when the first step of reading the RFID without a verification number is successful. It will be done.
Therefore, since one element of the authenticity of the inserted electronic certificate card has been confirmed, it is possible to increase the certainty of the user's age (in this embodiment, the certainty that the user is 20 years old or older).
In addition, this is limited to the case where the third step is negative (not pasted falsification).
Therefore, since we have confirmed the other factor that the inserted electronic certificate card is genuine, we can further increase the certainty of the user's age (in this embodiment, the certainty that he is 20 years old or older). Can be done.
Additionally, this is limited to the case where it is determined in the fourth step that the expiration date has not yet expired.
Therefore, since we have confirmed one more element that the inserted electronic certificate card is genuine, we can further increase the certainty of the user's age (in this embodiment, the certainty that he is 20 years old or older). be able to. Further, it is possible to prevent the use of an expired electronic certificate card.
Users only need to insert their electronic certificate card; there is no need to enter a verification number. Furthermore, since no attempt is made to read the area protected by the identification number of the electronic certificate card, there is no risk of the card being locked.
As described above, when age verification is required when purchasing a product or entering a facility, the age identification and recognition system uses an electronic certificate card with RFID as a means of verifying the age. To ensure the authenticity and age of a user's electronic certificate card without causing any inconvenience to the user.

Although the embodiment of the present invention has been described above, this embodiment is shown as an example, and it can be implemented in various other forms, and components may be omitted without departing from the gist of the invention. , can be replaced or modified.
Regardless of the above embodiments, the third step may not be adopted and the first step and the fourth step may be combined and implemented as the authentication condition, or the third step and the fourth step may not be adopted and the first step The step may be implemented as an authentication condition.
In addition, in the above embodiment, the age authentication that indicates that the person is 20 years old or older is output, but the judgment standard age such as 18 years old or older, 12 years old or younger, 30 to 50 years old, upper limit or lower limit, upper limit and lower limit, etc. It does not matter whether the person has the same or not. Furthermore, there may be no criterion age, and age information may be output.
In the above embodiment, the system is capable of handling three types of cards, but it is also possible to construct and implement a system that can handle only one type of card, only two types of cards, or four or more types of cards. good.
Furthermore, in the above embodiments, the user inserts the card, but it is also possible to perform RFID communication and scan the face of the card by touching the card to a predetermined reading surface. .
