(First embodiment)
First, a certificate determination device 1 according to a first embodiment of the present invention will be described with reference to FIG. The certificate determination device 1 according to the first exemplary embodiment of the present invention acquires image data of a certificate for authenticating a person to be authenticated, and determines whether to store the image data. The certificate determination apparatus 1 is realized by causing a general computer to execute a predetermined certificate determination program.

  The certificate determination device 1 is used, for example, at a site where healthy economic activity is required, such as an insurance company or a bank. The certificate determination apparatus 1 acquires image data of a certificate for customer identification and determines whether to store it as evidence data. When the condition as evidence data such as image quality is satisfied, the certificate determination apparatus 1 stores the image data.

  The person to be authenticated is an insurance contractor in an insurance company, a procedural person in a bank, etc., and a person to be authenticated.

  The certificate is, for example, a driver's license, various health insurance cards, pension notebooks, passports (passports), alien registration certificates, seal registration certificates for seals used for transactions, and preferably by a public institution. It is a document for identity verification to be issued. In the embodiment of the present invention, since the certificate is used for personal authentication, the type of certificate may be arbitrarily determined according to in-house rules, contract contents, and the like. For example, it may be a public certificate with a photograph such as a license or passport, or a private certificate such as an employee ID card may be acceptable.

  The certificate determination apparatus 1 according to the first embodiment of the present invention is used in a situation as shown in FIG. 2, for example. The certificate determination device 1 according to the first exemplary embodiment of the present invention is a portable information processing device such as a notebook computer. The certificate determination device 1 is used when a person in charge of business requiring personal authentication such as an insurance contract performs a procedure such as contract or change in a customer's house or workplace. The person in charge photographs the certificate presented by the customer using the image photographing device 2 when confirming whether or not the customer to be processed before the contract is the principal. The certificate image data photographed by the image photographing device 2 is input to the certificate determining device 1. The certificate determination apparatus 1 determines whether or not the image data satisfies the image quality as evidence data, and stores the evidence data when the image data satisfies the image quality. On the other hand, when the image quality is not satisfied, the certificate determination apparatus 1 displays the fact on the display screen and notifies the person in charge. The person in charge uses the image capturing device 2 to capture the certificate again.

  As shown in FIG. 3, the certificate determination apparatus 1 according to the first embodiment of the present invention includes a central processing control device 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, and an input / output interface. 109 are connected via the bus 110. An input device 104, a display device 105, a communication control device 106, a storage device 107, and a removable disk 108 are connected to the input / output interface 109.

  The central processing control device 101 reads and executes a boot program for starting the certificate determination device 1 from the ROM 102 based on an input signal from the input device 104, and further reads an operating system stored in the storage device 107. Further, the central processing control device 101 controls various devices based on input signals from the input device 104, the communication control device 106, etc., and reads programs and data stored in the RAM 103, the storage device 107, etc. into the RAM 103. A processing device that loads and implements a series of processing described later, such as data calculation or processing, based on a program command read from the RAM 103.

  The input device 104 includes input devices such as a keyboard and a mouse through which an operator inputs various operations. The input device 104 generates an input signal based on the operation of the operator, and inputs via the input / output interface 109 and the bus 110. It is transmitted to the central processing control apparatus 101. The display device 105 is a CRT (Cathode Ray Tube) display, a liquid crystal display, or the like, and receives an output signal to be displayed on the display device 105 from the central processing control device 101 via the bus 110 and the input / output interface 109. It is a device that displays the processing result of the control device 101 and the like. The communication control device 106 is a device such as a LAN card or a modem, and is a device that connects the certificate determination device 1 to a communication network such as the Internet or a LAN. Data transmitted / received to / from the communication network via the communication control device 106 is transmitted / received to / from the central processing control device 101 via the input / output interface 109 and the bus 110 as an input signal or an output signal.

  The storage device 107 is a semiconductor storage device or a magnetic disk device, and stores programs and data executed by the central processing control device 101. The removable disk 108 is an optical disk or a flexible disk, and signals read / written by the disk drive are transmitted / received to / from the central processing control apparatus 101 via the input / output interface 109 and the bus 110.

  The storage device 107 of the certificate determination device 1 according to the preferred embodiment of the present invention stores a certificate determination program, an image temporary data storage unit 21, a character recognition data storage unit 22, and an image data storage unit. 23. Further, when the certificate determination program is read and executed by the central processing control apparatus 101 of the certificate determination apparatus 1, the image acquisition unit 11, the character recognition unit 12, the determination unit 13, and the receipt notification unit 15 become the certificate determination unit. 1 is implemented.

  The image temporary data storage unit 21 is a storage area in the storage device 107 in which the certificate image data 21a is stored. The certificate image data 21a is captured and generated by the image capturing device 2 described later. Thereafter, the image data 21 a is stored in the image temporary data storage unit 21 by the image acquisition unit 11.

  The character recognition data storage unit 22 is a storage area in the storage device 107 in which character recognition data 22a is stored. The character recognition data 22 a is stored in the character recognition data storage unit 22 by the character recognition unit 12. The character recognition data 22a is data generated by converting a character image included in the image data 21a into a character code.

  The image data storage unit 23 is a storage area in the storage device 107 in which the image data 23a is stored. The image data 23 a is image data stored as evidence among the image data 21 a stored in the image temporary data storage unit 21. Whether or not to store the image data in the image data storage unit 23 is determined by the determination unit 13 of the certificate determination apparatus 1 described later. The image data 23a is preferably stored in association with the person to be authenticated or the contract of the person to be authenticated. The image data 23a may be stored as a part of a database such as a contract database.

  The image acquisition unit 11 stores the image data of the certificate of the person to be authenticated photographed by the image photographing device 2 in the image temporary data storage unit 21. The image data stored in the image temporary data storage unit 21 is used to determine whether or not to store the image data. When it is determined that the image data is stored as evidence data for a necessary period, the image data 21 a is copied and stored in the image data storage unit 23. On the other hand, when it is determined not to store the image data 21a, the image data stored in the image temporary data storage unit 21 is subsequently deleted. Alternatively, the image temporary data storage unit 21 may be deleted at a predetermined timing, for example, when the capacity of the image temporary data storage unit 21 exceeds a threshold value.

  The image photographing device 2 is a device that photographs a certificate as image data using a web camera, a digital camera, a camera-equipped mobile phone, or the like. The certificate image data photographed by the image photographing device 2 is input to the certificate determination device 1 via a USB cable, a portable memory, or the like. The image acquisition unit 11 stores this image data in the image temporary data storage unit 21. The image data photographed by the image photographing device 2 is judged by the determination means 13 described later whether or not the characters of the image data can be read and stored as evidence data. Therefore, in the embodiment of the present invention, the image capturing apparatus 2 may or may not have an autofocus function.

  The character recognition means 12 detects characters included in the image data 21a stored in the image temporary data storage unit 21, and stores the detected character data in the character recognition data storage unit 22 as character recognition data 22a. The character recognizing means 12 is a so-called OCR (Optical Character Reader), and collates with a character pattern stored in advance to specify a character included in the image data 21a. The character recognition unit 12 stores the specified character data in the character recognition data storage unit 22 as character recognition data 22a.

  The character recognition data 22a is data of characters described in a certificate read by the image capturing device 2. With reference to FIG. 4 thru | or FIG. 6, the character recognition data 22a of the license which is one of the certificates is demonstrated.

  FIG. 4 is a diagram for explaining the character recognition data 22a when all the characters included in the license can be read. In FIG. 4, all the characters included in the license are converted into character codes, and character recognition data 22a is generated. In FIG. 4, the symbol “◯” indicates actual data such as a name, and is not shown.

  FIG. 5 is a diagram for explaining the character recognition data 22a when a part of characters included in the license is not converted into a character code as an unread character. An unread character is a character whose character could not be identified by the character recognition means 12. In the example shown in FIG. 5, the unread character is converted to “?”. For example, when the image is photographed by the image photographing device 2 and the certificate is not in focus or when the light is reflected on the certificate, the character recognition unit 12 cannot convert the image data into the character code, and the character recognition data. 22a includes an unread character.

  FIG. 6 is a diagram for explaining the character recognition data 22a when a part of the characters included in the license is erroneously converted into character codes as misread characters. A misread character is one that has been identified by the character recognition means 12 but is different from the actual character of the certificate. In the example illustrated in FIG. 6, for example, a misread character that should be converted to “name”, a misread character that has been converted to “Mr. Taro”, or a misread character that has been converted to “month” It is included.

  As described above, the character recognition data 22a output by the character recognition unit 12 may be normally read or may include unread characters or misread characters. Based on such character recognition data 22 a, the determination unit 13 determines whether or not to store the image data 21 a in the image data storage unit 23.

  The determination unit 13 includes an image quality determination unit 14. The image quality determination unit 14 determines the image quality of the image data 21 a stored in the image temporary data storage unit 21, and stores the image data 21 a in the image data storage unit 23 when the image quality is equal to or higher than a certain standard. In the first embodiment of the present invention, the image quality determination unit 14 includes the item names of items necessary for authenticating the person to be authenticated in the character recognition data 22a stored in the character recognition data storage unit 22. Whether or not to store the image data 21a is determined based on the determination result. In the first embodiment, when the character data specified from the image data includes a predetermined item, it is determined that the image quality of the image data 21a is equal to or higher than the predetermined reference.

  Here, “items required to authenticate the person to be authenticated” are keywords for each item name such as name, date of birth, address, etc. It is. The “items necessary for authenticating the person to be authenticated” may differ depending on the type of certificate, the company rule for identity verification, and the like. In the case where personal authentication is possible using a plurality of certificates, the “items necessary for authenticating the person to be authenticated” are preferably item names that exist in common in each certificate.

  For example, in the case of the license shown in FIG. 4, the item name of “items necessary for authenticating the person to be authenticated” is considered to be the item name of the name and address. The date of birth is often used for identity verification, but the license does not include the item name of “birth date”, so it is listed as “an item necessary to authenticate the subject”. The item name “birth date” cannot be used. In the example shown in FIG. 4, the item names “name” and “address” are included in the character recognition data 22a. Therefore, the image data 21a corresponding to the character recognition data 22a shown in FIG. 4 is stored in the image data storage unit 23 assuming that the image quality satisfies the standard.

  In the example shown in FIG. 5, the item name “address” can be read. However, since the “name” of “name” is not read as an unread character, the item name “name” is not included in the character recognition data 22a shown in FIG. Accordingly, the image data 21a corresponding to the character recognition data 22a shown in FIG. 5 is not stored in the image data storage unit 23, assuming that the image quality does not satisfy the standard.

  In the example shown in FIG. 6, the item name “address” can be read. However, since “name” of “name” is recognized as “taro” as misread characters, the item name “name” is not included in the character recognition data 22a shown in FIG. Therefore, the image data 21a corresponding to the character recognition data 22a shown in FIG. 6 is not stored in the image data storage unit 23, assuming that the image quality does not satisfy the standard.

  In general, it is empirically known that what is generally used as a certificate, such as a license, insurance card, passport, etc., can read all characters if some characters can be read. In the first embodiment of the present invention, if attention is given to this, if some characters can be read, it can be expected that actual data such as names and addresses can be read, and processing can be performed quickly. Further, the image quality determination means 13 determines the image quality based on whether or not “the item name of an item necessary for authenticating the person to be authenticated” can be read, so that any certificate can be used regardless of the type of certificate. Since it can process similarly, the simplification and speeding-up of a process can be implement | achieved.

  In the above example, when the item names “name” and “address” are included in the character recognition data 22a, the image quality satisfies the standard. However, the present invention is not limited to this case. For example, as shown in FIG. 5 and FIG. 6, even if some of the characters are unread characters or misread characters, more than a predetermined number of characters of each item name of “name” and “address” can be read. The image quality may satisfy the standard. In the first embodiment of the present invention, the image quality may be determined based on the characters of “items necessary for authenticating the person to be authenticated”. The number or ratio of “items necessary for authentication” depends on in-house rules, hardware specifications such as the image capturing device 2 and the certificate determination device 1, contract details, required processing speed, and the like. It may be set arbitrarily.

  When the determination unit 14 determines to save the image data 21a, the receipt notifying unit 15 stores the image data 21a in the image data storage unit 23 and indicates that the certificate image data is stored in the person to be authenticated. Notice.

  The reception notifying unit 15 receives from the determination unit 13 a result as to whether or not to store the image data 21a as evidence data. When storing the image data 21 a as evidence data, the reception notifying unit 15 stores the image data 21 a in the image data storage unit 23. At this time, the image data 21a may be stored in the image data storage unit 23 in association with the identifier of the person to be authenticated or the contract identifier of the contract by the person to be authenticated. The image data 21a stored in the image data storage unit 23 is stored during the contract period. Even after the contract is terminated, it may be stored for a certain period thereafter.

  When the image data 21a is stored in the image data storage unit 23, the reception notifying means 15 notifies the person to be authenticated that the image data 21a has been saved as evidence data. This notification may be a notification for sending an email addressed to the email address of the person to be authenticated, or a notification by issuing and sending a receipt. As a result, the person to be authenticated can know how the image data of the certificate has been used, and can manage the personal information of the person to be authenticated.

  On the other hand, when the determination unit 13 receives a result indicating that the data is not stored as evidence data, the reception notification unit 15 ends the process without storing the image data 21a in the image data storage unit 23. For example, the image data 21a stored in the image temporary data 21 is deleted after a predetermined period. The notification unit 15 may delete the image data 21a stored in the image temporary data storage unit 21 and notify the user to that effect.

  With reference to FIG. 7, a certificate determination method according to the first embodiment of the present invention will be described. First, in step S <b> 101, the image acquisition unit 11 acquires image data of a certificate captured by the image capturing device 2 and stores it in the image temporary data storage unit 21.

  Next, in step S102, the character recognizing means 12 reads the image data 21a stored in the image temporary data storage unit 21, compares it with the dictionary data (not shown) of characters, and includes the characters included in the image data 21a. Is read and converted to character code. The character recognition means 12 converts all the characters included in the image data 21a into character codes and stores them as character recognition data 22a in the character recognition data storage unit 22.

  Next, in step S103, the image quality determination unit 14 of the determination unit 13 matches the codes of the character recognition data 22a and the keyword. In the first embodiment of the present invention, the keyword used in step S103 is an item name of an item necessary for authenticating the person to be authenticated, for example, an item name such as “address” or “name”. It is a string. In step S104, the determination unit 13 determines the image quality of the image data 21a based on the code matching result in step S103. For example, when all the keywords are included in the character recognition data 22a, it is determined that the image quality satisfies the standard, and the process proceeds to step S105. On the other hand, if the image quality does not satisfy the standard, the process returns to step S101. In step S <b> 101, the image acquisition unit 11 again displays an instruction to capture a certificate image by the image capturing apparatus 2 and waits for input of new image data.

  On the other hand, if it is determined in step S104 that the image quality satisfies the standard, the reception notifying unit 15 stores the image data 21a in the image data storage unit 23 in step S105. Further, the receipt notifying unit 15 notifies the person to be authenticated that the certificate image data has been stored, and ends the process.

  In the first embodiment of the present invention, recognition of characters included in image data obtained by photographing a certificate and determination on whether or not an item necessary for authenticating the person to be authenticated is included. Then, it is determined whether or not the image quality is above the standard. According to the certificate determination apparatus 1 as described above, since it is not necessary to consider the certificate type, format, character position, and certificate type, it is possible to realize a quick process. Therefore, the evidence data necessary for the processing can be acquired with a minimum waiting time of the customer.

  In addition, the certificate determination device 1 according to the first exemplary embodiment of the present invention can ensure the image quality as evidence data regardless of the performance of the image capturing device 2. Further, since the image capturing device 2 is relatively small and portable, it is not necessary to use a general scanner or the like. Therefore, it is possible to conclude a contract even if the office is not well-equipped, and it is also suitable for a visit contract such as a case where a sales representative contracts at a customer's dwelling unit.

  In addition, the certificate determination apparatus 1 according to the first embodiment of the present invention stores the image data in the image data storage unit 23 only when the image quality of the image data 21a satisfies a certain standard, and that is to be authenticated. The person in charge. Therefore, even if the certificate of the person to be authenticated is temporarily delivered to another person's hand, it can be used for its purpose, so that the usage of its own personal information can be grasped.

(Second Embodiment)
With reference to FIG. 8, the certificate determination apparatus 1a according to the second embodiment of the present invention will be described. The certificate determination device 1a according to the second embodiment of the present invention is different from the certificate determination device 1 according to the first embodiment of the present invention described with reference to FIG. The certificate type dictionary data storage unit 24 is provided, and the determination unit 13 of the central processing control apparatus 101 is different in that the type determination unit 16 is provided.

  The certificate type dictionary data storage unit 24 is a storage area in the storage device 107 in which the certificate type dictionary data 24a is stored. The certificate type dictionary data 24a is data in which a certificate type is associated with a condition for determining a certificate type from the character recognition data 22a. The certificate type dictionary data 24a may include only data related to a certificate that permits identity verification according to in-house rules. For example, in the case where identity verification with an insurance card is not permitted, the certificate type dictionary data 24a may not include the insurance card determination condition.

  The certificate type dictionary data 24a has, for example, the data structure and data example shown in FIG. The certificate type dictionary data 24a includes the determination condition for each certificate type. This determination condition is a condition that can be determined from the character recognition data 22a recognized by the character recognition means 12 from the image data 21a. In the second embodiment of the present invention, the determination condition is preferably a combination of a character string included in each certificate type and a character string not included.

  For example, the determination condition in the case where the certificate is a license is to include “number”, include “registration”, include “address”, and do not include “symbol”. This determination condition is preferably determined by the item name or title included in the license. On the other hand, actual data such as an address such as “Tokyo,...” Differs depending on the owner of the certificate, and is not suitable for the determination condition. Moreover, it is preferable that the determination condition includes not only the condition of the character string to be included but also the condition of the character string not to be included. In the example shown in FIG. 9, one of the determination conditions when the certificate is an insurance card is that it does not include “address”. Therefore, according to such certificate type dictionary data 24a, when the character recognition data 22a includes the character string “address”, the certificate that is the basis of the character recognition data 22a is not an insurance card, You can see that it is a license.

  As an example of the determination condition of the certificate type dictionary data 24a, the case of a combination of a character string included in each certificate type and a character string not included is described, but only the character string included in each certificate type is described. The determination condition may be used, or only a character string that is not included may be used as the determination condition.

  The type determination unit 16 compares the character recognition data 22a with the certificate type dictionary data 24a to determine the type of certificate. The type determination unit 16 compares the character recognition data 22a with the determination conditions included in the certificate type dictionary data 24a, and outputs a certificate type that satisfies all the determination conditions. The determination unit 13 determines whether or not to store the image data 21a as evidence data based on the determination result by the image quality determination unit 14 and the certificate type determined by the type determination unit 16. Specifically, the image quality determination means 14 confirms whether or not the image data 21a satisfies a predetermined image quality and the certificate is a type of certificate approved by the in-house rules. It is determined whether or not the certificate type is registered in advance in the book type dictionary data 24a.

  Next, a certificate determination method according to the second embodiment of the present invention will be described with reference to FIG. The certificate determination method according to the second embodiment of the present invention is different from the certificate determination method according to the first embodiment of the present invention described with reference to FIG. 7 in steps S203 to S205. Processing is different.

  First, in step S <b> 201, the image acquisition unit 11 acquires image data of a certificate captured by the image capturing device 2 and stores it in the image temporary data storage unit 21. In step S202, the character recognizing means 12 reads the image data 21a stored in the image temporary data storage unit 21, reads the characters included in the image data 21a, and compares them with character dictionary data (not shown). Convert to character code.

  Next, in step S203, the image quality determination unit 14 of the determination unit 13 matches the codes of the character recognition data 22a and the keyword. In step S204, the type determination unit 16 compares the character string included in the character recognition data 22a with the certificate type dictionary data 24a, and determines the type of the certificate that is the basis of the character recognition data 22a. The type determination unit 16 further determines whether or not the type of the certificate is a type of certificate that can be identified by the person, which is determined in advance in the company rules.

  In step S206, the determination unit 13 determines whether to store the image data 21a based on the determination results in steps S203 and S204. First, it is required that the image quality of the image data 21a satisfies the standard based on the determination result in step S203. Furthermore, in step S204, it is necessary that the type of certificate is a type of certificate that can be identified by a person, which is determined in advance by in-house rules. If these requirements are not satisfied, the process returns to step S201. In step S <b> 201, the image acquisition unit 11 again displays an instruction to capture a certificate image by the image capturing device 2 and waits for input of new image data.

  On the other hand, if it is determined in step S205 that the image quality and the certificate type satisfy the criteria, the reception notifying unit 15 stores the image data 21a in the image data storage unit 23 in step S206. Further, the receipt notifying unit 15 notifies the person to be authenticated that the certificate image data has been stored, and ends the process.

  In the example illustrated in FIG. 10, the image quality determination process in step S203 and the certificate type determination process in step S204 are described to be executed sequentially, but these processes may be executed in parallel. For example, after reading the character recognition data 22a, the image quality may be determined after determining the type of certificate. In such image quality determination processing, keyword codes may be matched in accordance with the certificate format in consideration of the certificate type. Further, the character reading process in step S202 may be executed again in consideration of the type of certificate. The accuracy of the determination in step S205 can be further improved by reading characters or matching keywords in consideration of the type of certificate.

  According to the certificate determination apparatus 1a according to the second embodiment as described above, it is possible to determine whether or not to store as evidence data in consideration of the type of certificate. Conventionally, a business operator or the like visually determines the type of certificate and determines whether or not it is appropriate as a document for identification, but according to the certificate determination device 1a according to the second embodiment, The determination of the type of certificate can be automated by computer processing. Therefore, it is possible to avoid human mistakes and process quickly.

(Third embodiment)
With reference to FIG. 11, a certificate determination apparatus 1b according to a third embodiment of the present invention will be described. Compared with the second embodiment of the present invention described with reference to FIG. 8, the certificate determination apparatus 1 b according to the third embodiment of the present invention has a determination unit 13 including an authenticity determination unit 17. Is different.

  If the certificate type determined by the type determination unit 16 is “license”, the authenticity determination unit 17 extracts the license identifier from the character recognition data 22a, and the check digit included in the identifier and a predetermined arithmetic expression To determine the validity of the certificate. When the certificate is valid, it is determined whether to save the image data 21a based on the determination results of the image quality determination unit 14 and the type determination unit 16. Here, that the certificate is valid means that the license is not issued as a forged but issued as a legitimate one. When a mechanism capable of confirming the forgery of the certificate is used in addition to the identifier, the authenticity determination means 17 determines whether the certificate has been forged using the mechanism. When the certificate is forged, the determination unit 13 does not store the image data 21 a corresponding to the certificate in the image data storage unit 23.

  A license number, which is a license identifier, may include a bit called a check digit. By checking the identifier of this bit with a predetermined arithmetic expression, it is possible to check whether the license number is correct and to determine the validity of the license.

  If the license is not valid, specifically, if it is forged, it can be displayed on the display device 105 to prompt the user not to proceed with the subsequent procedure.

  Next, with reference to FIG. 12, a certificate determination method according to the third embodiment of the present invention will be described. The certificate determination method according to the third embodiment of the present invention is different from the certificate determination method according to the second embodiment of the present invention described with reference to FIG. 10 in steps S306 to S311. Processing is different. The processing from step S301 to step S305 is the same as the processing from step S201 to step S205 in FIG.

  In step S306, it is determined whether or not the certificate type determined in step S304 is a license. If it is not a license, the receipt notifying means 15 stores the image data 21a in the image data storage unit 23 in step S307. Further, the receipt notifying unit 15 notifies the person to be authenticated that the certificate image data has been stored, and ends the process.

  On the other hand, if it is determined in step S306 that the certificate type is a license, the authenticity determination means 17 determines in step S308 whether the license has been forged. Specifically, the authenticity determination means checks using a check digit of the license number and confirms the forgery of the license.

  If it is determined in step S309 that the license has been forged, a message to that effect is displayed on the display device 105 in step S310, and the process ends. If it is determined that the license is not forged, the receipt notifying unit 15 stores the image data 21a in the image data storage unit 23 in step S311. Further, the receipt notifying unit 15 notifies the person to be authenticated that the certificate image data has been stored, and ends the process.

  The determination unit 13 of the certificate determination apparatus 1b according to the third embodiment, when the certificate type is a license, the image quality of the image data 21a determined by the image quality determination unit 13 is equal to or higher than a reference and is valid. If the license is recognized as a license, the image data 21a is stored in the image data storage unit 23 and stored. Where it is difficult to visually determine whether a license is forged or not, according to the certificate determination apparatus 1b according to the third embodiment, the validity of the license is determined using the check digit function of the license number. Can be traded properly.
