Description

[Technical field]

[0001] The present invention relates to an accounting system, and more particularly to an accounting system using biometric authentication. [Background technology]

[0002] Payment for goods and / or services is not limited to currency, but is also made using electronic data such as credit cards. When using electronic data, identity authentication is performed to prevent unauthorized use.

[0003] Furthermore, when entering a facility, such as at an airport or entering a data center, personal authentication is performed.

[0004] For personal authentication, authentication using information related to an individual's physical characteristics (biometrics information) is used (see, for example, Patent Documents 1 to 3).

[0005] It is desirable that the physical characteristics used as biometric information are characteristics that do not change much over a long period of time and are difficult for others to forge. For example, fingerprints, blood vessels, or irises are used as the physical characteristics.

[0006] The personal authentication payment system described in Patent Document 1 performs payment using the iris.

[0007] The car wallet payment system described in Patent Document 2 uses biometric authentication to authenticate a customer who is in a vehicle, and performs settlement processing and the like when the customer exits the vehicle.

[0008] The information processing system described in Patent Document 3 performs payment processing using a facial image of a customer. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2018-101420 A [Patent Document 2] JP 2004-227134 A [Patent Document 3] JP 2018-041181 A Summary of the Invention [Problem to be solved by the invention]

[0010] Biometric information is information that can identify an individual, and is one type of sensitive information that requires careful handling. In addition, it is preferable to provide biometric information as few times as possible. For example, users feel a large psychological burden when their biometric information is collected multiple times.

[0011] Furthermore, processing using biometric information such as an iris image involves a large number of pixels and is therefore a heavy load process, so it is desirable to reduce the number of times processing using biometric information.

[0012] However, the personal authentication payment system described in Patent Document 1 requires iris authentication for each payment.

[0013] In Patent Document 2, biometric information data is acquired at each store terminal.

[0014] The information processing system described in Patent Document 3 needs to capture facial images of customers multiple times (at least when they enter the store and when they make payment).

[0015] As described above, the inventions described in Patent Documents 1 to 3 have a problem in that biometric information needs to be acquired multiple times.

[0016] An object of the present invention is to provide an accounting system or the like which solves the above problems and reduces the number of times information on physical characteristics needs to be provided. [Means for solving the problem]

[0024] Next, an embodiment of the present invention will be described with reference to the drawings.

[0025] Each drawing is for explaining each embodiment. However, each embodiment is not limited to the description in each drawing. Also, the same numbers are given to similar configurations in each drawing, and repeated explanations may be omitted. Also, in the drawings used in the following explanation, the description of the configuration of the parts not related to the explanation of each embodiment may be omitted and may not be illustrated.

[0026] The physical characteristics unique to an individual (hereinafter referred to as "biometrics") used in each embodiment are not limited. For example, the biometrics may be a fingerprint, a blood vessel, an iris, or a combination of these. In the following description, "iris" is used as an example. However, this does not limit the target of each embodiment to the iris. Each embodiment is not limited to the biometrics used.

[0027] Furthermore, biometric information (biometric information) may be in a variety of formats, such as an image or voice. In the following description, an image (specifically, an iris image) will be used as an example of biometric information, but this is not intended to limit the embodiments.

[0028] The code used in each embodiment is generated based on biometric information (iris image). The code may be a one-dimensional code (e.g., a barcode) or a two-dimensional code (e.g., a QR code (registered trademark)). Alternatively, the code may use information equivalent to three dimensions, such as a hologram. In this way, a code is a numerical value converted into a predetermined shape.

[0029] In each embodiment, the code may be generated using a generation method that conforms to the specifications of each code.

[0030] Taking a barcode as an example, the operation of generating a code is as follows: The image to be converted into a code is converted into successive binary (0 and 1) data (serial data). Starting from either side (high or low), the "0"s and "1"s are converted into codes as follows: For "0", the number of successive "0"s (however, in the range of 1 to 4) is converted into four corresponding predetermined types of spaces (white rectangles). For "1", the number of successive "1"s (however, in the range of 1 to 4) is converted into four corresponding predetermined types of bars (black rectangles). A predetermined code (left and right guard bars, a center bar, and left and right margins) is added to the code, which is a combination of rectangles created in this way, to create a barcode.

[0031] In addition, applications for generating barcodes and the like are widely available, so each embodiment may use one of these applications.

[0032] However, in each embodiment, the format of the code used is not limited to the above.

[0033] It is preferable that the code is information with an amount of information reduced to such an extent that biometric information cannot be guessed from the code.

[0034] This is for the following reasons.

[0035] The code is information that is photographed and communicated during each accounting transaction. Accounting transactions are often carried out multiple times. Therefore, the code is information that may be photographed and communicated multiple times. And the more times the information is photographed and communicated, the higher the possibility that the information will be leaked to a third party. Therefore, in order to prevent the leakage of biometric information, it is desirable that the code be information that makes it impossible to infer biometric information from the code.

[0036] Furthermore, reducing the amount of information generally means reducing the amount of data. Therefore, communication of codes reduces the communication load between devices compared to communication of biometric information. Furthermore, processing of codes imposes a lower processing load compared to processing using biometric information.

[0037] Additionally, the code may contain other information in addition to biometric information.

[0038] Each embodiment performs accounting processing. However, each embodiment is not limited to the accounting processing to be performed. For example, accounting processing is a settlement process that consolidates deposits and withdrawals, or an individual deposit process or withdrawal process. Alternatively, accounting processing is debiting from an accounting account (e.g., a bank account) or paying into an account. Alternatively, accounting processing is setting up a debt for an individual (e.g., charging expenses to a credit card debit account). In the following description, as an example, accounting processing is charging expenses, etc. to a credit card debit account, unless otherwise specified.

[0039] <First embodiment> The first embodiment will be described below with reference to the drawings.

[0040] [Configuration Description] First, the configuration of a transaction system 400 according to the first embodiment will be described with reference to the drawings.

[0041] FIG. 1 is a block diagram showing an example of the configuration of a transaction system 400 according to the first embodiment.

[0042] The transaction system 400 includes an information display device 100 , an information processing device 200 , and an information providing device 300 .

[0043] 1 shows one of each device included in the accounting system 400. However, this is for the sake of clarity of the drawing, and does not limit the number of devices included in the accounting system 400. The number of each device included in the accounting system 400 is not limited to one. For example, the accounting system 400 may include multiple information processing devices 200.

[0044] The information display device 100 is connected to the information providing device 300 via a communication path. The information processing device 200 is connected to the information providing device 300 via a communication path. The above communication paths may be lines within the same network or may be different lines.

[0045] The information providing device 300 provides information to the information display device 100 and the information processing device 200 via a communication path.

[0046] The source of information provided by the information providing device 300 is not limited. For example, the information providing device 300 may obtain information from a device not shown when providing information, and provide the obtained information. However, for convenience of explanation, in the following explanation, it is assumed that the information providing device 300 stores information in advance.

[0047] The information providing device 300 may authenticate the information display device 100 and / or the information processing device 200.

[0048] For example, as will be described later, the information providing device 300 receives an iris image from the information display device 100. Then, the information providing device 300 may use the received iris information to determine whether or not the request is from a legitimate person (for example, the owner of the information display device 100).

[0049] The information display device 100 photographs the iris, obtains a code related to the photographed iris from the information providing device 300, and displays the obtained code.

[0050] The information processing device 200 photographs the code displayed by the information display device 100, obtains accounting information related to the photographed code from the information providing device 300, and performs accounting processing for the individual using the obtained accounting information. The accounting information and accounting processing are not limited. The accounting information is, for example, an account number. In this case, the accounting processing is, for example, charging expenses to that account.

[0051] When the accounting system 400 is applied to a shopping mall, for example, each device operates as follows.

[0052] The information providing device 300 is a device provided in a shopping mall operating company, a bank, etc. The information providing device 300 stores necessary information (for example, transaction information) in advance.

[0053] Information display device 100 is a device used by a shopping mall user. For example, when entering a shopping mall, the shopping mall user photographs his / her iris with information display device 100 (e.g., a mobile phone, etc.). Next, information display device 100 obtains a code related to the iris from information providing device 300 and stores it in information display device 100. Then, for example, when purchasing a product, the user operates information display device 100 to display the code.

[0054] The information processing device 200 is a device installed in a store in a shopping mall. An information processing device 200 is installed in each store. In other words, a plurality of information processing devices 200 are installed in a shopping mall and are connected by a wired or wireless communication path. The information processing device 200 may be a device carried by a salesperson of the store.

[0055] When a user purchases a product, a salesperson reads the code displayed on the information display device 100 using the information processing device 200. The information processing device 200 charges the price of the product to the account associated with the read code.

[0056] Furthermore, the information processing device 200 may use the code to change the price for the user. For example, the information processing device 200 may determine whether the user is a tax-exempt person or a taxable person. Alternatively, the information processing device 200 may determine whether the user is a general customer or a member. The information processing device 200 may obtain the information used for the above determination from the information providing device 300 as accounting information.

[0057] The shopping mall is an example of a facility in which the information processing device 200 is installed. The facility in which the information processing device 200 is installed is not limited to a shopping mall. For example, the facility in which the information processing device 200 is installed is an airport, an art gallery, a museum, an exhibition center, a library, or an amusement park.

[0058] In addition, at the time of entry, these facilities may authenticate visitors using their biometric information. In such cases, users of these facilities may obtain a code from the biometric information used for authentication at the time of entry (biometric authentication). For example, an authentication device at the facility may generate a code based on the biometric information used for authentication, and provide the generated code to the information display device 100.

[0059] The information providing device 300 may be an external device to the transaction system 400. In this case, the transaction system 400 only needs to obtain information from the external device equivalent to the information providing device 300 as necessary.

[0060] Next, the detailed configuration of each device will be described.

[0061] The information providing device 300 includes an information storage unit 310 and an information providing unit 320 .

[0062] The information storage unit 310 stores information used by the information display device 100 and the information processing device 200. The information storage unit 310 stores information that needs to be associated with each other in association with each other.

[0063] For example, in the description of this embodiment, the information storage unit 310 stores the following information:

[0064] The information storage unit 310 associates the iris image with the code and stores them. Furthermore, the information storage unit 310 associates the code with the transaction information and stores them.

[0065] The information storage unit 310 is not limited to a timing for storing information as long as it stores necessary information before a request from the information display device 100 or the like. Furthermore, the information storage unit 310 is not limited to a source from which information is transmitted. The information providing device 300 may receive and store information provided by a related device (e.g., a bank device) in advance.

[0066] The information storage unit 310 may store the above information as a set of information. Alternatively, the information storage unit 310 may store the above information as a set of multiple pieces of information. In this case, the information storage unit 310 may be configured using multiple components or devices. For example, the information storage unit 310 may be configured using a component (first storage unit) that associates and stores an iris image and a code, and a component (second storage unit) that associates and stores the code and payment information. Alternatively, the information providing device 300 may be configured as a combination of a device including the above-mentioned first storage unit and a device including the above-mentioned second storage unit.

[0067] Based on instructions from the information display device 100 and the information processing device 200, the information providing unit 320 provides information related to the instructions from the information stored in the information storage unit 310 by using the association between pieces of information.

[0068] When the information providing unit 320 is instructed by the information display device 100 to provide a code related to an iris image, the information providing unit 320 provides the code related to the iris image included in the instruction from among the codes stored in the information storage unit 310 to the information display device 100. Note that the information providing device 300 may perform authentication of the information display device 100 that transmits the code in order to improve security in the distribution of the code.

[0069] However, the iris image generated by the information display device 100 is not always the same even if the iris of the same person is used.

[0070] For example, the iris image changes depending on the position of the iris relative to the information display device 100. As a result, the iris images received by the information providing device 300 do not necessarily match, even if they are iris images of the same individual.

[0071] Therefore, the information providing unit 320 may allow a predetermined range of error in determining whether the iris image received from the information display device 100 matches the stored iris image in addition to a perfect match. For example, the information providing unit 320 may use a match of 95% or more as the match determination for the iris images. Alternatively, when the information storage unit 310 stores multiple iris images, the information providing unit 320 may determine that the iris image with the highest match rate is the matching iris image.

[0072] Furthermore, the information providing unit 320 may use image processing such as image movement, rotation, enlargement, reduction, deformation, and combinations thereof in determining whether the iris images match.

[0073] The information providing device 300 may create the code based on the iris image received from the information display device 100. In this case, the information providing device 300 does not need to include the information storage unit 310.

[0074] Alternatively, when the information providing unit 320 is instructed by the information processing device 200 to provide accounting information related to the code included in the instruction, it selects accounting information related to the code included in the instruction from the accounting information stored in the information storage unit 310 and provides it to the information processing device 200. Note that the information providing device 300 may authenticate the information processing device 200 that transmits accounting information to improve security in the distribution of accounting information.

[0075] Note that multiple methods may be used to generate a code from biometric information. In this case, the generated code may differ for each method. Therefore, the information providing device 300 may store a code for each method used by the accounting system 400 as a code to be associated with the accounting image.

[0076] Furthermore, for example, the code may include information indicating a method for generating the code. In this case, the information providing unit 320 may select a code to be compared by taking into consideration the generation method included in the code.

[0077] The information providing unit 320 may use a predetermined tolerance for the code match, similar to the determination of the match of the iris images.

[0078] The information display device 100 includes an image capturing section 110 (hereinafter also referred to as a “first image capturing section” as necessary), a code obtaining section 120, and a code display section .

[0079] The photographing unit 110 photographs a person or a part of a person and acquires the photographed image. For example, the photographing unit 110 photographs an iris and generates an iris image. Note that the photographing unit 110 may be an external device to the information display device 100. For example, the photographing unit 110 may be a camera installed at the entrance of a facility.

[0080] The code acquisition unit 120 acquires a code related to the iris from the information providing device 300 by using the iris image captured by the image capturing unit 110 (first image capturing unit).

[0081] The code display unit 130 displays the acquired code. For example, the code display unit 130 may include a liquid crystal display (not shown) and display the code on the liquid crystal display. The code display unit 130 may display the code on an external device (not shown). In this way, the code display unit 130 displays a code based on a physical feature unique to a person, such as the iris.

[0082] The information processing device 200 includes an image capturing unit 210 (hereinafter also referred to as a “second image capturing unit” as necessary), a transaction information acquisition unit 220, and a transaction processing unit 230.

[0083] The photographing unit 210 photographs the code displayed by the information display device 100 and outputs the photographed image data.

[0084] The transaction information acquisition unit 220 acquires transaction information from the information providing device 300 using the code from the image data.

[0085] The accounting processor 230 uses the acquired accounting information to execute accounting. For example, the accounting processor 230 charges the product price to a bank account.

[0086] In the above example, the iris photograph is taken only once. After that, the accounting system 400 can use the code to perform accounting processing (e.g., charging the product price to a debit account).

[0087] In this way, the payment system 400 can execute multiple payment transactions, such as purchases at multiple stores, while only transmitting information related to physical characteristics (for example, an iris image) once.

[0088] [Explanation of operation] Next, the operation of the transaction system 400 according to the first embodiment will be described with reference to the drawings.

[0089] FIG. 2 is a sequence diagram showing an example of the operation of the transaction system 400 according to the first embodiment.

[0090] The information providing device 300 stores necessary information in advance.

[0091] First, the information display device 100 captures an image of the iris (S401).

[0092] The information display device 100 transmits the iris image to the information providing device 300 (S402).

[0093] The information providing device 300 returns a code associated with the iris image (S403).

[0094] The information display device 100 displays the received code (S404).

[0095] The information processing device 200 captures an image of the code (S405).

[0096] The information processing device 200 transmits the photographed code data to the information providing device 300 (S406).

[0097] The information providing device 300 returns the transaction information associated with the code (S407).

[0098] The information processing device 200 executes the transaction process using the received transaction information (S408).

[0099] The transaction system 400 may repeat the above operations from S404 to S408. Additionally, multiple information processing devices 200 may execute the operations from S405 to S408.

[0100] [Effect description] Next, the effects of the accounting system 400 according to the first embodiment will be described.

[0101] The transaction system 400 according to the first embodiment has the advantage of reducing the number of times information about physical characteristics needs to be provided.

[0102] The reasons are as follows:

[0103] The transaction system 400 includes an information display device 100 and an information processing device 200. The information display device 100 includes an imaging unit 110 (first imaging unit), a code acquisition unit 120, and a code display unit 130. The imaging unit 110 images the person performing the transaction and acquires an image in which the person's unique physical characteristics are captured. The code acquisition unit 120 acquires a code associated with the image in which the person's unique physical characteristics are captured. The code display unit 130 displays the acquired code, that is, a code based on the person's unique physical characteristics. The information processing device 200 includes an imaging unit 210 (second imaging unit), a transaction information acquisition unit 220, and a transaction processing unit 230. The imaging unit 210 images the code displayed by the information display device 100. The transaction information acquisition unit 220 uses the captured code to acquire the person's transaction information. The transaction processing unit 230 executes transaction processing using the transaction information.

[0104] The information providing device 300 provides the information required above.

[0105] In the above-described accounting system 400, the information display device 100 can display a code any number of times based on a single capture of a biometric image. The information processing device 200 can then execute accounting any number of times using the code displayed on the information display device 100. Furthermore, multiple information processing devices 200 can execute accounting any number of times using the code displayed on the information display device 100.

[0106] In this way, the transaction system 400 can execute transaction processing multiple times on the information processing device 200 based on a single capture of a biometric image on the information display device 100.

[0107] Furthermore, because the transaction system 400 uses the code displayed on the information display device 100, it is possible to prevent the leakage of information relating to the physical characteristics of users.

[0108] The accounting system 400 may set a usage period or range for the code. For example, the accounting system 400 may limit the usage period of the code to the day on which the user enters a facility where the information processing device 200 is installed. Alternatively, the accounting system 400 may limit the number or range of information processing devices 200 on which the code can be used.

[0109] In this case, unauthorized use of the code on the information processing device 200 side can be prevented to some extent.

[0110] Furthermore, the transaction system 400 provides the effect of being able to carry out transaction processing without providing biometric information to a third party, such as the store where the information processing device 200 is installed.

[0111] The reason is that the information display device 100 displays a code to the information processing device 200, instead of biometric information.

[0112] [Outline of the embodiment] Next, an outline of the first embodiment will be described with reference to the drawings.

[0113] FIG. 3 is a block diagram showing an example of the configuration of a transaction system 401 according to the first embodiment.

[0114] The transaction system 401 includes an information display device 104 and an information processing device 200. The information display device 104 includes an imaging unit 110 (first imaging unit) and a code display unit 130. The imaging unit 110 images a person. The code display unit 130 displays a code based on physical characteristics unique to the imaged person. The information processing device 200 includes an imaging unit 210 (second imaging unit), a transaction information acquisition unit 220, and a transaction processing unit 230. The imaging unit 210 images the code displayed by the information display device 100. The transaction information acquisition unit 220 uses the imaged code to acquire the person's transaction information. The transaction processing unit 230 performs transaction processing using the transaction information.

[0115] The information display device 104 and the information processing device 200 are connected to a device equivalent to the information providing device 300 and acquire information. As described above, each component included in the transaction system 401 operates in the same way as the corresponding component in the transaction system 400.

[0116] The accounting system 401 configured in this way can achieve the same effects as the accounting system 400.

[0117] This is because each component of the transaction system 401 operates in the same manner as a similar component in the transaction system 400. In other words, the transaction system 401 can execute transaction processing multiple times using a single acquisition of physical characteristics.

[0118] The transaction system 401 is an example of a minimum configuration of the transaction system 400 in the first embodiment.

[0119] FIG. 4 is a block diagram showing an example of an overview of the information display device 104 according to the first embodiment.

[0120] The information display device 104 shown in Fig. 4 includes a configuration similar to that of the information display device 104 shown in Fig. 3. The information display device 104 is connected to a device having a function similar to that of the information providing device 300.

[0121] The information display device 104 includes an imaging unit 110 (first imaging unit) and a code display unit 130. The imaging unit 110 images a person. The code display unit 130 displays a code based on physical characteristics unique to the imaged person as a code imaged by a device equivalent to information processing device 200. The device equivalent to information processing device 200 images the code, uses the imaged code to obtain transaction information for the person, and performs transaction processing using the transaction information.

[0122] The information display device 104 thus configured uses each component to reduce the number of times information about physical characteristics is provided and displays the code.

[0123] The reason is that each component of information display device 104 shown in FIG. 4 operates in the same manner as the components of information display device 100 described with reference to FIG.

[0124] The information display device 104 shown in FIG. 4 is an example of a minimum configuration of the information display device 100 in the first embodiment.

[0125] FIG. 5 is a block diagram showing an example of an overview of the information processing device 200 according to the first embodiment.

[0126] The information processing device 200 shown in Fig. 5 includes the same configuration as the information processing device 200 shown in Fig. 1. The information processing device 200 is connected to a device having the same function as the information providing device 300.

[0127] The information processing device 200 includes an imaging unit 210 (second imaging unit), a transaction information acquisition unit 220, and a transaction processing unit 230. The imaging unit 210 captures the code displayed by a device equivalent to the information display device 100. The device equivalent to the information display device 100 captures an image of a person and displays a code based on the physical characteristics unique to the person captured. The transaction information acquisition unit 220 uses the captured code to acquire the person's transaction information. The transaction processing unit 230 carries out transaction processing using the transaction information.

[0128] The information processing device 200 configured in this manner uses each component to reduce the number of times information on physical characteristics is provided and executes accounting processing related to the code.

[0129] The reason is that each component of the information processing device 200 shown in FIG. 5 operates in the same manner as the components of the information processing device 200 described with reference to FIG.

[0130] The information processing device 200 shown in FIG. 5 is an example of a minimum configuration of the information processing device 200 in the first embodiment.

[0131] [Hardware configuration] Next, the hardware configurations of the information display device 100, the information processing device 200, and the information providing device 300 (hereinafter referred to as "information display device 100, etc.") will be described.

[0132] Each component of the information display device 100 may be configured as a hardware circuit.

[0133] Alternatively, in information display device 100 and the like, each component may be configured using a plurality of devices connected via a network.

[0134] Alternatively, in information display device 100 and the like, multiple components may be configured as a single piece of hardware.

[0135] Alternatively, the information display device 100 may be realized as a computer including a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). The information display device 100 may be realized as a computer including an input / output connection circuit (IOC) in addition to the above configuration. The information display device 100 may be realized as a computer including a network interface circuit (NIC) in addition to the above configuration.

[0136] FIG. 6 is a block diagram showing a configuration of an information processing device 600, which is an example of a hardware configuration of the information display device 100 according to the first embodiment.

[0137] The information processing device 600 includes a CPU 610, a ROM 620, a RAM 630, an internal storage device 640, an IOC 650, and a NIC 680, and constitutes a computer.

[0138] The CPU 610 loads a program from the ROM 620 and / or the internal storage device 640. Then, the CPU 610 controls the RAM 630, the internal storage device 640, the IOC 650, and the NIC 680 based on the loaded program.

[0139] A computer including CPU 610 controls these components and realizes the functions of information display device 100 and the like shown in Fig. 1. For example, a computer including CPU 610 realizes the functions of the photographing unit 110, code acquisition unit 120, and code display unit 130 in information display device 100. Alternatively, a computer including CPU 610 realizes the functions of the photographing unit 210, transaction information acquisition unit 220, and transaction processing unit 230 in information processing device 200. Alternatively, a computer including CPU 610 realizes the functions of the information storage unit 310 and information provision unit 320 in information provision device 300.

[0140] When realizing the function of the photographing unit 110 or the photographing unit 210, the computer including the CPU 610 may include a photographing device such as a camera (not shown). In this case, the photographing device photographs the iris based on an instruction from the CPU 610. For example, the computer including the CPU 610 may use an input device 660 (described later) as the photographing device used for the photographing unit 110 or the photographing unit 210. In this case, the computer including the CPU 610 may include the input device 660. However, the input device 660 does not have to be included in the computer.

[0141] When implementing each function, the CPU 610 may use the RAM 630 or the internal storage device 640 as a temporary storage medium for a program.

[0142] Furthermore, the CPU 610 may read the program contained in the recording medium 700, which stores the program in a computer-readable manner, using a storage medium reading device (not shown). Alternatively, the CPU 610 may receive the program from an external device (not shown) via the NIC 680, store it in the RAM 630 or the internal storage device 640, and operate based on the stored program.

[0143] The ROM 620 stores fixed data and programs executed by the CPU 610. The ROM 620 is, for example, a P-ROM (Programmable ROM) or a flash ROM.

[0144] The RAM 630 temporarily stores programs and data executed by the CPU 610. The RAM 630 is, for example, a dynamic RAM (D-RAM).

[0145] The internal storage device 640 stores data and programs that are to be stored long-term by the information processing device 600. The internal storage device 640 may also operate as a temporary storage device for the CPU 610. The internal storage device 640 is, for example, a hard disk device, a magneto-optical disk device, an SSD (Solid State Drive), or a disk array device.

[0146] The ROM 620 and the internal storage device 640 are non-volatile (non-transitory) storage media. On the other hand, the RAM 630 is a volatile (transitory) storage medium. The CPU 610 can operate based on a program stored in the ROM 620, the internal storage device 640, or the RAM 630. In other words, the CPU 610 can operate using a non-volatile storage medium or a volatile storage medium.

[0147] The IOC 650 mediates data between the CPU 610 and the input device 660 and display device 670. The IOC 650 is, for example, an IO interface card or a Universal Serial Bus (USB) card. Furthermore, the IOC 650 is not limited to being wired like a USB, and may be wireless.

[0148] The input device 660 is a device that receives an input instruction from an operator of the information processing device 600. The input device 660 is, for example, a keyboard, a mouse, or a touch panel. The input device 660 may be an image capturing device used in the image capturing unit 110 or the image capturing unit 210.

[0149] The display device 670 is a device that presents information to an operator of the information processing device 600. For example, the code display unit 130 may display a code on the display device 670. The display device 670 is, for example, a liquid crystal display, an organic electroluminescence display, or electronic paper.

[0150] The NIC 680 relays data between the information display device 100 and the like via a network, and between the information display device 100 and an external device (not shown). The NIC 680 is, for example, a LAN (Local Area Network) card. Furthermore, the NIC 680 is not limited to being wired, and may be wireless.

[0151] The information processing device 600 configured in this manner can achieve the same effects as the information display device 100 and the like.

[0152] The reason is that the CPU 610 of the information processing device 600 can realize the same functions as the information display device 100 and the like based on a program.

[0153] <Second embodiment> Iris images are sensitive information. It is preferable to communicate iris images using a secure communication channel. It is also preferable that an individual's iris image is not associated with that individual's accounting information.

[0154] Therefore, as the second embodiment, a transaction system 402 that improves the security of iris image communication will be described. Note that in the following description, configurations and operations that are the same as those in the first embodiment will be omitted as appropriate.

[0155] Fig. 7 is a block diagram showing an example of the configuration of a transaction system 402 according to the second embodiment. Note that Fig. 7 does not limit the number of devices included in the transaction system 402. For example, the transaction system 402 may include multiple information processing devices 200. Furthermore, each device constituting the transaction system 402 may be configured using the computer shown in Fig. 6. Note that when each device is realized using a computer, the transaction system 402 may include photographing equipment such as a camera, as necessary.

[0156] The accounting system 402 includes an information display device 101 , an information processing device 200 , an information providing device 301 , and an information providing device 302 .

[0157] The information providing device 301 includes an information storage unit 311 and an information providing unit 321 .

[0158] The information storage unit 311 stores information to be provided to the information display device 101. In the description of the present embodiment, the information storage unit 311 stores an iris image and a code in association with each other. However, this is not intended to limit the present embodiment. The information stored by the information storage unit 311 is not limited to the above.

[0159] The information providing unit 321 provides the information display device 101 with a code related to the iris image received from the information display device 101 .

[0160] The information providing device 302 includes an information storage unit 312 and an information providing unit 322 .

[0161] The information storage unit 312 stores information to be provided to the information processing device 200. In the description of this embodiment, the information storage unit 312 stores the code and transaction information in association with each other. However, this is not intended to limit the embodiment. The information stored by the information storage unit 311 is not limited to the above.

[0162] The information providing unit 322 provides the information processing device 200 with transaction information related to the code received from the information processing device 200 .

[0163] The configuration of the information processing device 200 is the same as in the first embodiment. However, the information processing device 200 is connected to an information providing device 302. As in the first embodiment, the information processing device 200 uses the captured code to obtain transaction information from the information providing device 302 and executes the transaction process. The information processing device 200 does not need to be connected to the information providing device 301 that stores the iris image.

[0164] The information display device 101 includes a code storage unit 140 and an instruction acquisition unit 150 in addition to the components of the information display device 100 .

[0165] The code acquisition unit 120 acquires a code associated with the iris image captured by the image capture unit 110 from the information providing device 301. Then, the code acquisition unit 120 requests the code storage unit 140 to store the acquired code.

[0166] Furthermore, the code acquisition unit 120 acquires the code stored in the code storage unit 140 based on the instruction, and displays it on the code display unit 130.

[0167] The code storage unit 140 stores the code.

[0168] Furthermore, the code storage unit 140 may store multiple codes, not just one code, as the code associated with the captured iris image. In this case, the code acquisition unit 120 may select a code to be displayed from the multiple codes based on a selection rule. For example, the code acquisition unit 120 may randomly select a code each time it is displayed.

[0169] Furthermore, the code acquisition unit 120 is not limited to a timing for changing the code to be displayed. For example, the code acquisition unit 120 may change the code when the number of times the code is displayed exceeds a predetermined number. Alternatively, the code acquisition unit 120 may change the code at predetermined time intervals. Alternatively, the code acquisition unit 120 may acquire an instruction regarding the selection of the code to be displayed from the instruction acquisition unit 150, which will be described later.

[0170] The instruction acquisition unit 150 receives an instruction to display the code on the information display device 101 .

[0171] The instruction acquisition unit 150 is, for example, a switch, a key, or a touch panel in the information display device 101. Alternatively, the instruction acquisition unit 150 may be an acceleration sensor or a rotation sensor included in the information display device 101.

[0172] Then, the information display device 101 operates as follows.

[0173] The information display device 101 photographs the iris in advance using the photographing unit 110, obtains a code related to the iris image from the information providing device 301 using the code obtaining unit 120, and stores the code in the code storage unit 140. It is desirable that the communication path used by the information display device 101 to obtain the code from the information providing device 301 is a secure communication path (for example, a direct connection using a cable or the like, a dedicated line, or an intranet connection within a facility where security is ensured).

[0174] Then, the code acquisition unit 120 displays the code stored in the code storage unit 140 on the code display unit 130 based on an instruction from the instruction acquisition unit 150 .

[0175] The code storage unit 140 may store the iris image in association with the code. In this case, the code acquisition unit 120 operates, for example, as follows.

[0176] First, the code acquisition unit 120 acquires in advance a code related to the iris image captured by the image capture unit 110 from the information providing device 301. Then, the code storage unit 140 stores the iris image and the code in association with each other.

[0177] Then, the code acquisition unit 120 acquires the iris image captured by the imaging unit 110 based on an instruction from the instruction acquisition unit 150. Then, the code acquisition unit 120 determines whether or not the captured iris image matches the iris image stored in the code storage unit 140. Then, if there is a match, the code acquisition unit 120 acquires the code stored in the code storage unit 140. Then, the code display unit 130 displays the acquired code.

[0178] Furthermore, the code storage unit 140 may store a plurality of iris images in association with a code related to each iris image. In this case, the code acquisition unit 120 may operate as follows.

[0179] The code acquisition unit 120 acquires an iris image using the photographing unit 110 based on an instruction from the instruction acquisition unit 150. Then, the code acquisition unit 120 compares the iris image stored in the code storage unit 140 with the acquired iris image, and acquires the code associated with the iris image that most closely matches. Then, the code acquisition unit 120 displays the acquired code on the code display unit 130.

[0180] As explained above, the communication path and communication partner (information providing device 302) that the information processing device 200 uses to obtain transaction information from the code are different from the communication path and communication partner (information providing device 301) that the information display device 101 uses to obtain the code from the iris image. Therefore, the information processing device 200 cannot obtain the iris image related to the code. In other words, the transaction system 402 can reduce the possibility of iris image leakage.

[0181] Furthermore, if the checkout system 402 uses a highly secure communication path between the information display device 101 and the information providing device 301, the checkout system 402 can further reduce the possibility of iris image leakage.

[0182] When code storage unit 140 stores a code in association with an iris image, code acquisition unit 120 may capture an iris image based on an instruction from instruction acquisition unit 150, and acquire the code associated with an iris image that matches the captured iris image among the stored iris images. In this case, accounting system 402 can protect the display of the code when the person who previously saved the iris image in information display device 101 (for example, the owner of information display device 101) is absent.

[0183] The information display device 101 may set a limit on the period for which the code stored in the code storage unit 140 is to be stored or on the number of times the code acquisition unit 120 is to acquire the code. For example, when the code acquisition unit 120 has acquired the code a predetermined number of times, the information display device 101 may delete the code stored in the code storage unit 140 and request the user of the information display device 101 or the like to acquire the code again.

[0184] Alternatively, the information display device 101 may discard the code based on the location, range, etc. For example, the information display device 101 may discard a code stored upon entry into a specific facility, upon exit from the facility.

[0185] [Effect description] Next, the effects of the transaction system 402 according to the second embodiment will be described.

[0186] In addition to the effects of the first embodiment, the transaction system 402 according to the second embodiment can provide the effect of improving the security of biometric information (for example, iris images).

[0187] The reason is that the information processing device 200 uses a communication path for obtaining transaction information using a code that is different from the communication path used by the information display device 101 to receive a code using an iris image.

[0188] When a highly secure communication path is used as a path through which the information display device 101 obtains the code, the checkout system 402 can further improve the security of communication of iris images.

[0189] When the code storage unit 140 stores a code in association with an iris image, the accounting system 402 has the advantage of protecting the display of the code when the owner of the information display device 101 is absent.

[0190] The reason is that the code acquiring unit 120 captures a new iris image based on an instruction from the instruction acquiring unit 150, and acquires a code related to the captured iris image.

[0191] <Third embodiment> The information display device 100 may generate a code directly from an iris image without using the information providing device 300. Therefore, as a third embodiment, a case where the information display device 100 generates a code will be described. In the following description, configurations and operations similar to those of the first and second embodiments may be omitted as appropriate.

[0192] FIG. 8 is a block diagram showing an example of the configuration of a transaction system 403 according to the third embodiment.

[0193] It should be noted that Figure 8 does not limit the number of devices included in the accounting system 403. For example, the accounting system 403 may include multiple information processing devices 200. Furthermore, each device constituting the accounting system 403 may be configured using the computer shown in Figure 6. It should be noted that when each device is realized using a computer, the accounting system 403 may include photographing equipment such as a camera, as necessary.

[0194] The transaction system 403 includes an information display device 102 , an information processing device 200 , and an information provision device 302 .

[0195] The information processing device 200 and the information providing device 302 are similar to those in the second embodiment.

[0196] The information display device 102 includes a code generation unit 160 in addition to the configuration of the information display device 100 .

[0197] The code generating unit 160 generates a code from the iris image captured by the imaging unit 110.

[0198] The code acquisition unit 120 acquires the code from the code generation unit 160 .

[0199] The other configurations are similar to those of the first embodiment.

[0200] It should be noted that the generation of the code in the information display device 102 is not limited to one time. For example, the information display device 102 may regenerate the code after a predetermined time has elapsed or when the number of times the code has been displayed exceeds a predetermined number. In this case, the information display device 102 may display a request for regeneration of the code on a display unit (not shown).

[0201] Alternatively, if the information display device 102 includes the instruction acquisition unit 150, the information display device 102 may regenerate the code based on an instruction from the instruction acquisition unit 150.

[0202] [Effect description] Next, the effects of the accounting system 403 according to the third embodiment will be described.

[0203] In addition to the effects of the first embodiment, the transaction system 403 according to the third embodiment can achieve the effect of avoiding communication of iris images (that is, biometric information).

[0204] The reason is that the information display device 102 generates a code from the biometric information.

[0205] In the third embodiment, there is no need to transmit biometric information, and therefore the third embodiment can further improve the security of biometric information compared to the second embodiment.

[0206] <Fourth embodiment> Identifiers (IDs) are widely used as information for identifying individuals. The accounting system 400 may use a combination of a biometric image and an identifier.

[0207] Therefore, as a fourth embodiment, an example in which an identifier is used will be described.

[0208] FIG. 9 is a block diagram showing an example of the configuration of a transaction system 404 according to the fourth embodiment.

[0209] It should be noted that Figure 9 does not limit the number of devices included in the accounting system 404. For example, the accounting system 404 may include multiple information processing devices 200. Furthermore, each device constituting the accounting system 404 may be configured using the computer shown in Figure 6. It should be noted that when each device is realized using a computer, the accounting system 404 may also include photographing equipment such as a camera, as necessary.

[0210] The accounting system 404 includes an information display device 103 , an information processing device 200 , and an information provision device 303 .

[0211] The information providing device 303 includes an information storage unit 313 and an information providing unit 323 .

[0212] The information storage unit 313 includes an iris image, an ID (identifier), a code, and accounting information.

[0213] The information storage unit 313 associates the iris image with the ID and stores them. For example, the information providing device 303 identifies an individual using image authentication or the like for the acquired iris image, associates the identified individual's ID with the iris image, and stores them in the information storage unit 313. Alternatively, the information providing device 303 may acquire the iris image, ID, and information associating them from a device not shown, and store the iris image and ID in association with each other.

[0214] Furthermore, the information storage unit 313 stores the ID and the code in association with each other.

[0215] Furthermore, the information storage unit 313 stores the code in association with the transaction information.

[0216] In this embodiment, the code may be generated using data that combines an iris image and an ID as the original data of the code. In this manner, the code may be generated from information that combines biometric information with other information related to the individual. Biometric information such as an iris image is information that is at least partially unstable. In contrast, an ID is information that does not change. Therefore, when a code is generated using an ID, the generated code is more stable than when it is generated using biometric information. In other words, when a code is generated using an ID, the matching accuracy of the code is improved.

[0217] The accounting system 404 may use authentication data to authenticate the code. In other words, the accounting system 404 may receive authentication data in addition to the code as information that the information providing device 303 receives from the information processing device 200.

[0218] The accounting system 404 may use, as the authentication data, for example, a hash obtained by applying the ID to a hash function.

[0219] However, the authentication data is not limited to a hash of the ID. For example, the code may be generated including part of the ID (for example, a certain number of upper or lower bits). In this case, the accounting system 404 may simply use the bits of the ID that are not included in the code as the authentication data. The information providing device 303 can authenticate the code based on a comparison of the combination of the bits included in the code and the bits included in the authentication data with the ID.

[0220] The information providing unit 323 provides information to the information display device 103 and the information processing device 200 .

[0221] Compared with the information display device 100 of the first embodiment, the information display device 103 includes a code acquisition unit 121 instead of the code acquisition unit 120, and further includes an ID acquisition unit 170.

[0222] The ID acquisition unit 170 acquires an ID from the information providing device 303 by using the iris image from the image capturing unit 110. The ID acquisition unit 170 may be called an identifier acquisition unit.

[0223] The code acquisition unit 121 acquires a code from the information providing device 303 using the ID.

[0224] The code display unit 130 displays the code.

[0225] The information processing device 200 operates in the same manner as the information processing device 200 of the first embodiment.

[0226] When the accounting system 404 uses authentication data, each device operates, for example, as follows.

[0227] The information display device 103 obtains authentication data in addition to the code from the information providing device 303. Then, the information display device 103 provides the authentication data to the information processing device 200. For example, the information display device 103 provides the authentication data to the information processing device 200 using short-range communication. Since the code is displayed on a display device, it may be photographed from a remote location. However, the authentication data cannot be obtained from a remote location. In this way, the authentication data has a different level of security than the code.

[0228] The information processing device 200 transmits the authentication data acquired from the information display device 103 to the information providing device 303 in accordance with the code.

[0229] The information providing device 303 uses the code and authentication data to authenticate the information processing device 200. The information providing device 303 then provides transaction information to the authenticated information processing device 200.

[0230] [Effect description] Next, the effects of the accounting system 404 according to the fourth embodiment will be described.

[0231] In addition to the effects of the first embodiment, the accounting system 404 achieves the effect of improving the accuracy of code matching.

[0232] This is because the accounting system 404 generates the code using the ID in addition to the biometric information.

[0233] Furthermore, when authentication data is used, the transaction system 404 has the added benefit of improving the reliability of the transaction information provided.

[0234] Incidentally, identifiers (IDs) are widely used in general information processing systems. For example, accounting system 404 can realize the main required components by adding components related to iris images to a general accounting system. In other words, accounting system 404 has the advantage that it is easier to build from a general accounting system compared to the first embodiment and the like.

[0235] <Fifth embodiment> The left and right irises are different. That is, for each individual, two iris images are required to identify the individual. Therefore, as the fifth embodiment, an embodiment using two iris images of an individual will be described.

[0236] The fifth embodiment will be described below using the accounting system 400 in Fig. 1. However, this does not limit the fifth embodiment to the accounting system 400 shown in Fig. 1. The fifth embodiment may be applied to the second to fourth embodiments.

[0237] In the following description, the description of the configuration and operation similar to those of the first embodiment will be omitted, and the contents unique to the fifth embodiment will be described. In the following description, an image related to the iris of one eye will be called the "iris image of one eye", and a code related to the iris image of one eye will be called the "code of one eye". Moreover, an image related to the irises of both eyes will be called the "iris image of both eyes", and a code related to the iris images of both eyes will be called the "code of both eyes". The same applies to the left and right eyes.

[0238] The information display device 100 displays either a code for one eye or a code for both eyes in response to an instruction (for example, a key operation) from a user of the information display device 100.

[0239] The information processing device 200 captures an image of the code displayed by the information display device 100 and transmits the captured image of the code to the information providing device 300 .

[0240] The information providing unit 320 of the information providing device 300 determines whether the received code is a code for one eye or a code for both eyes, and changes the transaction information provided to the information processing device 200 based on the result of this determination.

[0241] For example, when the information providing unit 320 receives a code for one eye, it provides information on an account with a low credit limit as the accounting information. On the other hand, when the information providing unit 320 receives a code for both eyes, it provides information on an account with a high credit limit as the accounting information. This is because using iris images of both eyes is safer than using an iris image of one eye.

[0242] Alternatively, for example, when the information providing unit 320 receives a code for one eye, it provides information on a bank account for a transfer as the accounting information. On the other hand, when the information providing unit 320 receives codes for both eyes, it may provide information on a bank account for a withdrawal as the accounting information.

[0243] In this way, the transaction information acquired by the transaction information acquisition unit 220 using the code for one eye is at least partially different from the transaction information acquired using the code for both eyes. In this case, "different" includes the presence or absence of information, i.e., the case where the transaction information is inclusive.

[0244] Alternatively, the information display device 100 may distinguish between the right eye code and the left eye code. In this case, the information providing unit 320 may change the accounting information to be provided based on the distinction between the left and right sides of the code.
