Description

Information processing device, wearable device, information processing method, and recording medium

[0001] The present disclosure relates to the technical fields of an information processing device, a wearable device, an information processing method, and a recording medium.

[0002] Patent Literature 1 describes a biometric authentication system including a measuring device that measures biometric information of a subject and an authentication device that communicates with the measuring device. In the biometric authentication system described in Patent Literature 1, the measuring device determines whether the measuring device is worn by the subject, and if it determines that the measuring device is worn by the subject, causes a light-emitting means to emit light in a predetermined light-emitting pattern. The authentication device simultaneously photographs the subject and the predetermined light-emitting pattern, and authenticates the subject and the measuring device based on the photographed subject and the predetermined light-emitting pattern. If it determines that the measuring device has been removed from the subject during measurement of the subject's biometric information, the authentication device causes the light-emitting means to emit light again when the measuring device is reattached to the subject, and if it receives notification from the measuring device that the measuring device has been removed from the subject, performs authentication again.

[0003] Patent Literature 2 discloses various aspects directed to a wearable identity manager system. In a first aspect, an association status between a user and a wearable identity manager device is confirmed based on whether the wearable identity manager device is worn by the user, and motion data associated with the movement of the wearable identity manager device is monitored. Authentication data including the motion data is then transmitted based on the association status. In another aspect, the association status between the user and the wearable identity manager device is again determined based on whether the wearable identity manager device is worn by the user. The wearable identity manager device is paired with a pairing device, and authentication data is transmitted to the pairing device based on the association status to facilitate user authentication via the pairing device.

[0004] Patent Document 3 discloses a credit card payment system that allows member information stored in an electronic commerce database server to be used not only for electronic commerce transactions but also in physical stores. In the credit card payment system described in Patent Document 3, an identification processing device reads a member identification code issued by the electronic commerce database server and an arbitrary and unique two-dimensional code attached to an identification attachment. This links the member identification code to the identification attachment for a specified period of time only. The member then conducts a commercial transaction using the identification attachment. At a sales floor or other location, a sales processing device reads the two-dimensional code on the identification attachment and a sales information code issued by a sales tally register. The member identification code and sales information code read by both devices are linked via the identification attachment, and the electronic commerce database server links and stores the member information and sales information as credit card payment information, thereby performing the credit card payment.

[0005] Patent Document 4 describes a technology for preventing the fraudulent use of electronic ticket terminals. In the technology described in Patent Document 4, a storage unit stores identification information of a wearable electronic ticket terminal used by a user to enter a restricted area, in association with a facial image previously acquired of the user carrying the wearable electronic ticket terminal. A communication unit is capable of communicating with the wearable electronic ticket terminal and a surveillance camera that captures images of the surrounding areas through which the user may pass when entering the restricted area. When wearing detection information indicating that a person has been wearing the wearable electronic ticket terminal is received from the wearable electronic ticket terminal together with the identification information, the facial image corresponding to the stored identification information is compared with a facial image extracted from an image captured by the surveillance camera.

[0013] Hereinafter, embodiments of an information processing apparatus, a wearable device, an information processing method, and a recording medium will be described with reference to the drawings. [1: First Embodiment]

[0014] A first embodiment of an information processing device, a wearable device, an information processing method, and a recording medium will be described below. Hereinafter, the first embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing device 10 to which the first embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied. [1-1: Configuration of Information Processing Device 10]

[0015] 1 is a block diagram showing the configuration of an information processing device 10 according to the first embodiment. As shown in FIG. 1, the information processing device 10 includes an association unit 11, a biometric information acquisition unit 12, an attachment identification information acquisition unit 13, and a determination unit 14.

[0016] The associating unit 11 associates a living organism with an attachment worn by the living organism. The biometric information acquiring unit 12 acquires biometric information collected from the living organism. The attachment identification information acquiring unit 13 acquires attachment identification information that can uniquely identify the attachment worn by the living organism. The determining unit 14 determines whether the living organism is wearing the attachment associated with the living organism by the associating unit 11, based on the biometric information and the attachment identification information. [1-2: Technical Effects of the Information Processing Device 10]

[0017] The information processing device 10 in the first embodiment determines whether the living body is wearing the attachment associated with the living body by the association unit 11, thereby ensuring that the living body and the attachment are reliably associated. Since the determination unit 14 makes the determination, it is possible to prevent the living body from being swapped with another living body, and for another living body from wearing the attachment and impersonating the living body. [2: Second embodiment]

[0018] Next, a second embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described below. Hereinafter, the second embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S2 to which the second embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied.

[0019] The information processing system S2 to which the second embodiment is applied may be applied, for example, to the authentication of workers in a factory. In particular, it may be applied to authentication in cases where it is difficult to collect biometric information, such as when working under a car. It may also be applied to the authentication of people in an office. In particular, it may be applied to the authentication of people who handle confidential information that requires strict authentication. It may also be applied, for example, to the authentication of people who are permitted to use a specific service. Or, the information processing system S2 may be applied to the authentication of people who are temporarily permitted to act in a specific area, such as a theme park. [2-1: Overall Configuration of Information Processing System S2]

[0020] FIG. 2 is a conceptual diagram of an information processing system S2 according to the second embodiment. As shown in FIG. 2, the information processing system S2 according to the second embodiment may include an information processing device 20, a wearable device D2, a device reading device 300, and a camera CAM. The wearable device D2 may be worn by a person to be authenticated as a living body. The device reading device 300 may read, from the wearable device D2 worn by the person to be authenticated, wearable item identification information that can uniquely identify the wearable device D2. The camera CAM may capture an image of the person to be authenticated wearing the wearable device D2. The information processing device 20 may acquire an image from the camera CAM and acquire the wearable item identification information from the device reading device 300 to associate the person to be authenticated with the wearable device D2. [Wearable Device D2]

[0021] In the second embodiment, the wearable device D2 as an attachment includes a first presenting unit D21 that presents attachment identification information that can uniquely identify the wearable device D2. The first presenting unit D21 may present the attachment identification information that can uniquely identify the wearable device D2 by radio waves. The first presenting unit D21 may also present the attachment identification information only to authenticated devices. The wearable device D2 may be an RF tag worn by the person to be authenticated. The RF tag may include tags conforming to various standards such as RFID and NFC.

[0022] The wearable device D2 may be a passive RF tag. A passive RF tag is an electronic circuit that does not have a built-in power source, but passively stores an ID by obtaining power from radio waves emitted by a reader and a writer, and passively transmits an ID by obtaining power from radio waves emitted by a reader and a writer. When the wearable device D2 is a passive RF tag, the wearable device D2 does not process information itself, and does not need to perform intelligent operations such as stopping the transmission of wearable item identification information or invalidating wearable item identification information.

[0023] The wearable device D2 may be an active RF tag. An active RF tag is an electronic circuit that has a built-in power source and actively transmits an ID to the surrounding area using radio waves. When the wearable device D2 is an active RF tag, the wearable device D2 may process information by itself and perform intelligent operations such as stopping transmission of the wearable item identification information and invalidating the wearable item identification information depending on its own state.

[0024] The wearable device D2 may be a device such as a smartphone equipped with a wireless communication function that transmits wearable item identification information via radio waves. The wearable device D2 may also include a radio wave beacon that transmits location information. [Device reader 300]

[0025] The device reading device 300 may be an authenticated authorized device to which the wearable device D2 presents the wearable item identification information. The wearable device D2 and the device reading device 300 may perform an authentication operation with each other.

[0026] The device reading device 300 may write the attachment identification information to the wearable device D2. Conversely, a third party other than the device reading device 300 cannot write the attachment identification information to the wearable device D2. The device reading device 300 may register the written attachment identification information in a storage medium. The device reading device 300 may perform authentication by calculating an exact match between the registered attachment identification information and the read attachment identification information. In this case, the device reading device 300 can perform authentication instantly, so the person to be authenticated does not have to wait. Furthermore, in this case, the device reading device 300 can perform authentication using an inexpensive embedded CPU.

[0027] Furthermore, the device reading device 300 may not be able to read the ID of a counterfeit device from the counterfeit device. In this case, the counterfeit device will not be authenticated by the device reading device 300. Furthermore, a third party will not be able to read the attachment identification information from the wearable device D2. This prevents the wearable device D2 from being spoofed, and the authenticity of the wearable device D2 is guaranteed.

[0028] If the wearable device D2 is a passive RF tag, the person to be authenticated may hold the wearable device D2 over the device reading device 300 to have the device reading device 300 read the wearable item identification information.

[0029] If the wearable device D2 is an active RF tag, the device reading device 300 may receive radio waves emitted by the wearable device D2 from a position, for example, 10 meters or more away from the wearable device D2. In this case, the person to be authenticated does not need to hold the wearable device D2 over the device reading device 300. Furthermore, if the wearable device D2 is an active RF tag, the device reading device 300 may measure the position of the radio waves emitted by the wearable device D2.

[0030] Note that the configuration shown in FIG. 2 is an example, and devices other than those shown in FIG. 2 may be added, or some devices may not be provided. Also, some devices may be replaced with other devices having similar functions. Also, some functions of this embodiment may be provided by other devices via a network. The functions of this embodiment may be distributed and realized among multiple devices. Or, for example, the information processing device 20 may have the functions of the device reading device 300. Or, the information processing device 20 may be equipped with a camera CAM. The components included in the information processing system S2, excluding the wearable device D2, may be integrated or separate. [2-2: Configuration of the information processing device 20]

[0031] 3 is a block diagram of an information processing device 20 according to the second embodiment. As shown in FIG. 3, the information processing device 20 includes a calculation device 21 and a storage device 22. The information processing device 20 may further include a communication device 23, an input device 24, and an output device 25. However, the information processing device 20 does not necessarily have to include at least one of the communication device 23, the input device 24, and the output device 25. The calculation device 21, the storage device 22, the communication device 23, the input device 24, and the output device 25 may be connected via a data bus 26.

[0032] The arithmetic device 21 includes, for example, at least one of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and an FPGA (Field Programmable Gate Array). The arithmetic device 21 reads a computer program. For example, the arithmetic device 21 may read a computer program stored in the storage device 22. For example, the arithmetic device 21 may read a computer program stored in a computer-readable, non-transitory recording medium using a recording medium reading device (e.g., an input device 24, described later) not shown in the drawings provided in the information processing device 20. The arithmetic device 21 may acquire (i.e., download or read) the computer program from a device (not shown) located outside the information processing device 20 via the communication device 23 (or another communication device). The arithmetic device 21 executes the read computer program. As a result, logical functional blocks for executing the operations that the information processing device 20 should perform are realized within the arithmetic device 21. In other words, the arithmetic device 21 can function as a controller for realizing logical functional blocks for executing the operations (in other words, processing) that the information processing device 20 should perform.

[0033] 3 shows an example of logical functional blocks implemented within the computing device 21 to execute information processing operations. As shown in FIG. 3, the computing device 21 includes a correspondence unit 211, which is a specific example of the "correspondence unit" described in the appendix below, a biometric information acquisition unit 212, which is a specific example of the "biometric information acquisition unit" described in the appendix below, an attachment identification information acquisition unit 213, which is a specific example of the "attachment identification information acquisition unit" described in the appendix below, a determination unit 214, which is a specific example of the "determination unit" described in the appendix below, an image acquisition unit 215, which is a specific example of the "image acquisition unit" described in the appendix below, and an authentication unit 216, which is a specific example of the "authentication unit" described in the appendix below. However, the computing device 21 does not necessarily have to include at least one of the image acquisition unit 215 and the authentication unit 216. The operations of the association unit 211, biometric information acquisition unit 212, attachment identification information acquisition unit 213, determination unit 214, image acquisition unit 215, and authentication unit 216 will be described in detail later with reference to FIG.

[0034] The storage device 22 can store desired data. For example, the storage device 22 may temporarily store a computer program executed by the arithmetic device 21. The storage device 22 may temporarily store data that the arithmetic device 21 temporarily uses when the arithmetic device 21 is executing a computer program. The storage device 22 may store data that the information processing device 20 stores long-term. The storage device 22 may include at least one of a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, a magneto-optical disk device, an SSD (Solid State Drive), and a disk array device. In other words, the storage device 22 may include a non-temporary recording medium.

[0035] The communication device 23 can communicate with devices external to the information processing device 20 via a communication network (not shown). The information processing device 20 may transmit and receive signals to and from the device reading device 300 and the camera CAM via the communication device 23.

[0036] The input device 24 is a device that accepts information input to the information processing device 20 from outside the information processing device 20. For example, the input device 24 may include an operation device (e.g., at least one of a keyboard, a mouse, and a touch panel) that can be operated by an operator of the information processing device 20. For example, the input device 24 may include a reading device that can read information recorded as data on a recording medium that can be externally attached to the information processing device 20.

[0037] The output device 25 is a device that outputs information to the outside of the information processing device 20. For example, the output device 25 may output information as an image. That is, the output device 25 may include a display device (a so-called display) that can display an image showing the information to be output. For example, the output device 25 may output information as sound. That is, the output device 25 may include an audio device (a so-called speaker) that can output sound. For example, the output device 25 may output information on paper. That is, the output device 25 may include a printing device (a so-called printer) that can print desired information on paper. [2-3: Information Processing Operation Performed by the Information Processing Device 20]

[0038] Next, the information processing operation performed by the information processing device 20 in the second embodiment will be described with reference to Fig. 4. Fig. 4 is a diagram showing the flow of the information processing operation performed by the information processing device 20 in the second embodiment.

[0039] 4, the image acquisition unit 215 acquires an image of the person to be authenticated wearing the wearable device D2 (step S20). The image acquisition unit 215 may acquire an image captured by the camera CAM via the communication device 23. The image acquired by the image acquisition unit 215 may be an image including at least the part of the person to be authenticated from which biometric information was collected and the part of the person to be authenticated where the wearable device D2 is worn.

[0040] The biometric information acquisition unit 212 acquires biometric information collected from the person to be authenticated (step S21). The biometric information acquisition unit 212 may acquire biometric information collected from the person to be authenticated who is wearing the wearable device D2. The biometric information acquisition unit 212 may acquire biometric information collected from the person to be authenticated when the person to be authenticated wears the wearable device D2. Alternatively, the biometric information acquisition unit 212 may acquire biometric information collected from the person to be authenticated before wearing the wearable device D2. The biometric information acquisition unit 212 may acquire, for example, a face image or iris image of the person to be authenticated included in the image acquired by the image acquisition unit 215 as the biometric information.

[0041] The first matching unit 2111 performs first matching using biometric information (step S22). As the first matching, the first matching unit 2111 may perform biometric authentication using an image of the person to be authenticated wearing the wearable device D2. The first matching unit 2111 may perform, for example, face authentication using a face image or iris authentication using an iris image. If the first matching is successful, the first matching unit 2111 may determine that the person to be authenticated is the person in question.

[0042] The second verification unit 2112 detects in-image attachment information related to the attachment device D2 included in the image (step S23). The in-image attachment information may be information presented by the attachment device D2 appearing in the image. The in-image attachment information may be information that can uniquely identify the attachment device D2.

[0043] The attachment identification information acquisition unit 213 acquires attachment identification information that can uniquely identify the attachment device D2 from the attachment device D2 worn by the person to be authenticated (step S24). The attachment identification information acquisition unit 213 may acquire, from the device reading device 300, attachment identification information that the device reading device 300 reads from the attachment device D2.

[0044] The second matching unit 2112 performs a second matching using the in-image attachment information and the attachment identification information (step S25). The second matching unit 2112 may check whether the attachment device D2 in the image corresponds to the attachment device D2 that presented the attachment identification information. The second matching unit 2112 may determine that the attachment identification information is reliable identification information because the identification information acquired by different acquisition methods and different acquisition routes corresponds to each other. If the second matching is successful, the second matching unit 2112 may determine that the attachment identification information acquired by the attachment identification information acquisition unit 213 is identification information that can uniquely identify the attachment device D2 attached to the living body.

[0045] The third matching unit 2113 detects in-image biometric information related to the person to be authenticated that is included in the image (step S26). The in-image biometric information may include information related to the body part of the person to be authenticated from which the biometric information was collected.

[0046] The third matching unit 2113 detects attachment biometric information related to the attachment worn by the person to be authenticated (step S27). The attachment biometric information may be information related to both the body of the person to be authenticated and the wearable device D2. The attachment biometric information may be information presented by the wearable device D2. The third matching unit 2113 performs third matching using the in-image biometric information and the attachment biometric information (step S28). If the third matching is successful, the third matching unit 2113 may guarantee that the wearable device D2 is indeed worn by the person to be authenticated.

[0047] The association unit 211 determines whether all of the first, second, and third matching are successful (step S29). If all of the matching is successful (step S29: Yes), the association unit 211 associates the person to be authenticated with the wearable device D2 worn by the person to be authenticated (step S30). That is, the association unit 211 associates the person to be authenticated with the wearable device D2 worn by the person to be authenticated based on the first matching performed by the first matching unit 2111, the second matching performed by the second matching unit 2112, and the third matching performed by the third matching unit 2113.

[0048] The association unit 211 may determine that the attachment identification information presented by the wearable device D2 is as reliable as the authentication subject's biometric information, based on the fact that the authentication subject is the person to be authenticated, that the attachment identification information presented by the wearable device D2 is reliable identification information, and that the wearable device D2 is indeed worn by the authentication subject. The association unit 211 may associate the biometric information collected from the authentication subject with the attachment identification information that can uniquely identify the wearable device D2, and store association information 221 that associates the biometric information with the attachment identification information in the storage device 22. The information processing device 20 may manage the association between the authentication subject and the wearable device D2 using the association information 221.

[0049] When the association unit 211 associates the person to be authenticated with the wearable device D2, the authentication unit 216 authenticates the person to be authenticated using the attachment identification information (step S31). After the association by the association unit 211 is completed, the authentication unit 216 may perform authentication using the attachment identification information presented by the worn wearable device D2 as an alternative to biometric authentication. In other words, when the association unit 211 guarantees the identity of the wearable device D2 worn by the person to be authenticated, the authentication unit 216 may authenticate the person to be authenticated using the attachment identification information.

[0050] For example, the operations of steps S20 to S30 may be authentication operations performed before work starts, such as at an entrance to a specific area of ​​an office, a factory, etc. The person to be authenticated may wear the wearable device D2 before the authentication operations before work starts are performed. The association unit 211 may associate the authenticated person with the authenticated wearable device D2.

[0051] After the association is performed by the association unit 211, the authentication unit 216 may perform, as an alternative to biometric authentication, belonging authentication using the attachment identification information of the wearable device D2 received by the device reading device 300. Furthermore, the information processing device 20 may record the behavior of the person to be authenticated in a specific area such as an office or a factory, based on the attachment identification information received by the device reading device 300.

[0052] In the second embodiment, the determination unit 214 may determine whether the person to be authenticated is wearing the wearable device D2 associated with the person to be authenticated by the association unit 211 based on an operation similar to at least one of the first, second, and third matching performed by the association unit 211. The determination unit 214 may perform an operation after the association unit 211 associates the living body with the wearable device D2. The determination unit 214 may also perform an operation to confirm that the association is maintained. For example, when the person to be authenticated wears the wearable device D2 for a long period of time, the determination unit 214 may periodically determine whether the combination of the person to be authenticated and the wearable device D2 has changed. Even when the combination of the person to be authenticated and the wearable device D2 has not changed, for example, if the information stored in the wearable device D2 is corrupted due to a malfunction of the wearable device D2, the wearable device D2 may no longer be able to perform the expected operation, and the wearable device D2 may no longer be able to authenticate the person to be authenticated. The operation of the determination unit 214 is useful even when the device needs to be replaced with a new one.

[0053] The associating unit 211 and the determining unit 214 can verify the association between the living body wearing the wearable device D2 and the wearable device D2 when the living body is wearing the wearable device D2. Due to the operations of the associating unit 211 and the determining unit 214, there is no risk of impersonation even when multiple people are present around the device reading device 300.

[0054] In the second embodiment, facial authentication and iris authentication are given as examples of the first authentication in S22, but the first authentication may be fingerprint authentication, palm print authentication, vein authentication, ear acoustic authentication, etc. [2-4: Technical Effects of the Information Processing Device 20]

[0055] The information processing device 20 in the second embodiment can guarantee the identity of the person to be authenticated and the wearable device D2. The information processing device 20 associates the biometric information collected from the person to be authenticated with attachment identification information that can uniquely identify the wearable device D2, and therefore the attachment identification information presented by the wearable device D2 can be used as information that is as reliable as the biometric information of the person to be authenticated.

[0056] For example, laws and regulations require that inspections of finished products at factories be recorded by workers with special qualifications. While a worker's signature on a book or other document could be used as an inspection record, book or document records can be easily forged. Biometric authentication, such as facial recognition and iris recognition, is useful as a record that is difficult to forge and can record evidence that a specific person was present at a location. However, there is a trade-off between the accuracy of biometric authentication and the burden placed on the person being authenticated. For example, high-precision biometric authentication, such as facial recognition or iris recognition, requires the person to face a camera for several seconds, placing a heavy burden on the person being authenticated. In contrast, reducing the burden on the person by shortening the time the person faces the camera may reduce authentication accuracy and result in false recognition. Furthermore, high-precision biometric authentication may involve movements that interfere with the person's work. Therefore, requiring biometric authentication for each inspection of each finished product may reduce work efficiency, making it difficult to adopt. For example, in offices that handle confidential information, strict authentication is required even for access to cabinets, multifunction printers, etc. Although biometric authentication is useful as a strict authentication method, in cases where work involves frequent access to various confidential information, requiring biometric authentication for each access can reduce work efficiency, making adoption difficult in many cases. Furthermore, at events where hundreds or thousands of people enter and exit at the same time, for example, using biometric authentication to identify individuals entirely can impede people's movement. Furthermore, installing biometric authentication devices in various devices and locations is costly. As such, there is a demand for human authentication that has the same accuracy as high-precision biometric authentication without interfering with people's movements.

[0057] In contrast, the information processing system S2 in the second embodiment guarantees the identity of the person to be authenticated and the wearable device D2, and can use the attachment identification information presented by the wearable device D2 as information as reliable as the biometric information of the person to be authenticated. Therefore, it is possible to achieve person authentication with accuracy equivalent to highly accurate biometric authentication without interfering with the person's movements.

[0058] Since biometric information such as fingerprint images, face images, and iris images differ from person to person, uniqueness can be guaranteed with sufficient accuracy. In other words, the authenticity of the biometric information can be guaranteed. According to this embodiment, authentication is achieved based on the biometric authentication of the person to be authenticated, making it extremely difficult for a third party to impersonate the person, and it is possible to guarantee the authenticity of the person to be authenticated.

[0059] This embodiment can realize both the advantages of biometric authentication and the guarantee of uniqueness. By combining biometric authentication, which has extremely high authentication accuracy, with personal item authentication using the wearable device D2, which places less burden on the person to be authenticated, it is possible to realize highly accurate and convenient personal authentication even in situations where it is difficult to apply biometric authentication. [3: Third Embodiment]

[0060] Next, a third embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described below. Hereinafter, the third embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S3 to which the third embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied.

[0061] The configuration of an information processing system S3 in the third embodiment will be described with reference to Fig. 5. Fig. 5 is a block diagram showing the configuration of an information processing system S3 in the third embodiment.

[0062] As shown in FIG. 5 , the information processing system S3 of the third embodiment differs from the information processing system S2 of the second embodiment in that it includes a wearable device D3 instead of the wearable device D2. The wearable device D3 also differs from the wearable device D2 in that it includes a second display unit D32. The second display unit D32 displays in-image wearable item identification information as second identification information that can be captured in an image and uniquely identifies the wearable device D3. That is, the wearable device D3 not only displays the wearable item identification information via radio waves or the like, but also displays in-image wearable item identification information that uniquely corresponds to the wearable item identification information. Other features of the information processing system S3 may be the same as those of the information processing system S2. Therefore, the following will describe in detail the differences from the previously described embodiments, and will omit appropriate descriptions of other overlapping features.

[0063] The wearable device D3 may be provided with a function of presenting a unique ID that can be reflected in the image as the second presenting unit D32 when the device reading device 300 writes the wearable item identification information. In addition to writing the wearable item identification information to the electronic circuit of the wearable device D3, the device reading device 300 may print, for example, in-image wearable item identification information such as characters, one-dimensional codes such as barcodes, or matrix-type two-dimensional codes on the surface of the wearable device D3. Note that a device different from the device reading device 300 may print the in-image wearable item identification information on the surface of the wearable device D3. A user of the information processing system SYS3 may attach a printed matter on which the in-image wearable item identification information is printed to the surface of the wearable device D3. [3-1: Information Processing Operation Performed by the Information Processing Device 30]

[0064] The information processing operation performed by the information processing device 30 in the third embodiment will be described with reference to Fig. 6. Fig. 6 is a diagram showing the flow of the information processing operation performed by the information processing device 30 in the third embodiment.

[0065] As shown in FIG. 6, the image acquisition unit 215 acquires an image of the person to be authenticated wearing the wearable device D3 (step S20).

[0066] The biometric information acquisition unit 212 acquires a face image as biometric information from the image acquired in step S20 (step S32). The first matching unit 2111 performs face authentication of the person to be authenticated using the face image of the person to be authenticated acquired in step S32 (step S33).

[0067] The second matching unit 2112 detects in-image attachment identification information that is captured in the image acquired in step S20 and presented by the second presentation unit D32, and that can uniquely identify the attachment device D3 (step S34). The in-image attachment identification information may be, for example, a one-dimensional code such as characters or a barcode, or a matrix-type two-dimensional code, presented by the second presentation unit D32. The in-image attachment identification information may be, for example, a flashing light signal that can uniquely identify the attachment device D3, presented by the second presentation unit D32. In this case, the image acquired by the image acquisition unit 215 may be a moving image.

[0068] The attachment identification information acquisition unit 213 acquires attachment identification information that can uniquely identify the attachment device D3 from the attachment device D3 worn by the person to be authenticated (step S24). The attachment identification information acquisition unit 213 may acquire the attachment identification information that is read by the device reading device 300 and presented by the first presentation unit D21 from the device reading device 300 via the communication device 23.

[0069] The second matching unit 2112 performs attachment matching as a second matching using the in-image attachment identification information and the attachment identification information (step S35). The second matching unit 2112 may match the attachment device D3 identified by the in-image attachment identification information with the attachment device D3 identified by the attachment identification information. That is, the second matching unit 2112 may determine whether the attachment device D3 that presented information captured in the image acquired by the image acquisition unit 215 and the attachment device D3 that output the attachment identification information acquired by the attachment identification information acquisition unit 213 are the same device.

[0070] The third matching unit 2113 detects in-image biometric information related to the person to be authenticated contained in the image (step S26). The third matching unit 2113 detects attachment biometric information related to an attachment worn by the person to be authenticated (step S27). The third matching unit 2113 performs third matching using the in-image biometric information and the attachment biometric information (step S28).

[0071] The association unit 211 determines whether all of the face authentication, the attachment matching, and the third matching are successful (step S29). If all of the matching is successful (step S29: Yes), the association unit 211 associates the person to be authenticated with the wearable device D3 worn by the person to be authenticated based on the face authentication performed by the first matching unit 2111, the attachment matching performed by the second matching unit 2112, and the third matching performed by the third matching unit 2113 (step S30). If the association unit 211 associates the person to be authenticated with the wearable device D3, the authentication unit 216 authenticates the person to be authenticated using the attachment identification information (step S31).

[0072] In the third embodiment, iris authentication using a face image is performed in step S33, but biometric authentication using an image, such as iris authentication using an iris image, may be performed instead of face authentication. [3-2: Technical Effects of the Information Processing Device 30]

[0073] In the information processing system S3 of the third embodiment, the wearable device D3 not only presents a unique ID via radio waves or the like, but also presents information that uniquely corresponds to the unique ID by a method that can be captured in an image, such as a one-dimensional code such as a character or a barcode, a two-dimensional matrix code, or a flashing light. This allows the in-image wearable item identification information to be captured in the image along with the person to be authenticated, making it possible to verify the association between the person to be authenticated and the wearable device D3 from the image. The information processing system S3 can guarantee the identity of the wearable device D3 when worn by the person to be authenticated. [4: Fourth Embodiment]

[0074] Next, a fourth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described. Hereinafter, the fourth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S4 to which the fourth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied.

[0075] The information processing system S4 in the fourth embodiment differs from the information processing system S3 in the third embodiment in the operation of the third collation unit 2113. Other features of the information processing system S4 may be the same as other features of the information processing system S3. Therefore, the following will describe in detail the parts that differ from the already described embodiments, and will omit descriptions of other overlapping parts as appropriate. [4-1: Information Processing Operation Performed by Information Processing Device 40]

[0076] Next, the information processing operation performed by the information processing device 40 in the fourth embodiment will be described with reference to Fig. 8. Fig. 8 is a diagram showing the flow of the information processing operation performed by the information processing device 40 in the fourth embodiment.

[0077] As shown in FIG. 8, the image acquisition unit 215 acquires an image of the person to be authenticated wearing the wearable device D4 (step S20).

[0078] The biometric information acquisition unit 212 acquires an iris image as biometric information from the image acquired in step S20 (step S40). The first matching unit 2111 performs iris authentication of the person to be authenticated using the iris image of the person to be authenticated acquired in step S40 (step S41).

[0079] The second matching unit 2112 detects in-image attachment identification information presented by the wearable device D4 that can uniquely identify the wearable device D4 and that appears in the image acquired in step S20 (step S34). The attachment identification information acquisition unit 213 acquires, from the wearable device D4 worn by the person to be authenticated, attachment identification information that can uniquely identify the wearable device D4 (step S24). The second matching unit 2112 performs attachment matching as the second matching using the in-image attachment identification information and the attachment identification information (step S35).

[0080] The third matching unit 2113 detects joint position information indicating the positions of predetermined joints of the person to be authenticated included in the image and collection position information indicating the position where an iris image as biometric information of the person to be authenticated included in the image was collected (step S42). The third matching unit 2113 detects wearing position information indicating the position where the wearable device D4 is worn on the person to be authenticated included in the image (step S43). The position where the wearable device D4 is worn on the person to be authenticated included in the image may be the position of the in-image wearing object identification information presented by the wearable device D4 detected in step S34.

[0081] The third matching unit 2113 performs position verification using the joint position information, the collection position information, and the wearing position information (step S44). The third matching unit 2113 may, for example, verify whether the joint position information, the collection position information, and the wearing position information have a natural positional relationship. The third matching unit 2113 may detect predetermined joint positions of the person to be authenticated from the same image and compare the positions of the body parts where biometric authentication was performed with the position of the wearable device D4 to verify that the person who performed biometric authentication and the person wearing the wearable device D4 are the same person.

[0082] The association unit 211 determines whether all of the iris authentication, attachment matching, and position verification are successful (step S29). If all of the matching is successful (step S29: Yes), the association unit 211 associates the person to be authenticated with the attachment device D4 worn by the person to be authenticated based on the iris authentication performed by the first matching unit 2111, the attachment matching performed by the second matching unit 2112, and the position verification performed by the third matching unit 2113 (step S30). If the association unit 211 associates the person to be authenticated with the attachment device D4, the authentication unit 216 authenticates the person to be authenticated using the attachment identification information (step S31).

[0083] In the fourth embodiment, iris authentication using an iris image is performed in step S41, but biometric authentication using an image, such as face authentication using a face image, may be performed instead of iris authentication. [4-2: Technical Effects of the Information Processing Device 40]

[0084] The information processing system S4 in the fourth embodiment can verify that the person who performed the biometric authentication and the person who wears the wearable device D4 are the same person, based on the positions of the predetermined joints of the person to be authenticated, the positions of the body parts where the biometric authentication was performed, and the position of the wearable device D4, which are included in the image. [5: Fifth Embodiment]

[0085] Next, a fifth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described. Hereinafter, the fifth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S5 to which the fifth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied.

[0086] The information processing system S5 in the fifth embodiment differs from the information processing system S3 in the third embodiment and the information processing system S4 in the fourth embodiment in the operation of the third collation unit 2113. Furthermore, in the fifth embodiment, the wearable device D5 may be a device capable of measuring pulse, such as a smart watch. Other features of the information processing system S5 may be the same as other features of the information processing system S3 or the information processing system S4. Therefore, in the following, differences from the embodiments already described will be described in detail, and descriptions of other overlapping parts will be omitted as appropriate. [5-1: Information Processing Operation Performed by the Information Processing Device 50]

[0087] Next, the information processing operation performed by the information processing device 50 in the fifth embodiment will be described with reference to Fig. 10. Fig. 10 is a diagram showing the flow of the information processing operation performed by the information processing device 50 in the fifth embodiment.

[0088] As shown in FIG. 10, the image acquisition unit 215 acquires an image of the person to be authenticated wearing the wearable device D5 (step S20).

[0089] The biometric information acquisition unit 212 acquires a face image as biometric information from the image acquired in step S20 (step S32). The first matching unit 2111 performs face authentication of the person to be authenticated using the face image of the person to be authenticated acquired in step S32 (step S33).

[0090] The second matching unit 2112 detects in-image attachment identification information presented by the wearable device D5 that can uniquely identify the wearable device D5 and that appears in the image acquired in step S20 (step S34). The attachment identification information acquisition unit 213 acquires, from the wearable device D5 worn by the person to be authenticated, attachment identification information that can uniquely identify the wearable device D5 (step S24). The second matching unit 2112 performs attachment matching as the second matching using the in-image attachment identification information and the attachment identification information (step S35).

[0091] The third matching unit 2113 detects the first pulse of the person to be authenticated based on the image (step S60). The third matching unit 2113 may detect the first pulse of the person to be authenticated based on a facial image. The third matching unit 2113 may detect the first pulse of the person to be authenticated from a change in color of the skin surface of the face, which is the biometric authentication part in the image.

[0092] The third verification unit 2113 acquires the second pulse of the person to be authenticated detected by the wearable device D5 (step S61). The wearable device D5 may transmit information indicating the second pulse to the information processing device 50 by presenting information that can be captured in an image, such as emitting a flashing light from an LED or the like, or by emitting a radio wave signal. Alternatively, the device reading device 300 may read the second pulse detected by the wearable device D5, and the third verification unit 2113 may acquire the second pulse of the person to be authenticated from the device reading device 300.

[0093] The third verification unit 2113 performs pulse verification as third verification using the first pulse and the second pulse (step S62). The third verification unit 2113 may verify whether the timing of the first pulse and the second pulse coincides.

[0094] The association unit 211 determines whether all of the face authentication, attachment matching, and pulse verification are successful (step S29). If all of the matching is successful (step S29: Yes), the association unit 211 associates the person to be authenticated with the attachment device D5 worn by the person to be authenticated based on the face authentication performed by the first matching unit 2111, the attachment matching performed by the second matching unit 2112, and the pulse verification performed by the third matching unit 2113 (step S30). If the association unit 211 associates the person to be authenticated with the attachment device D5, the authentication unit 216 authenticates the person to be authenticated using the attachment identification information (step S31). [5-2: Technical Effects of the Information Processing System S5]

[0095] The information processing system S5 in the fifth embodiment can verify that the person who performed biometric authentication and the person who wears the wearable device D5 are the same person, based on pulse verification using the first pulse and the second pulse. [6: Sixth Embodiment]

[0096] Next, a sixth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described. Hereinafter, the sixth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S6 to which the sixth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied. [6-1: Overall configuration of the information processing system S6]

[0097] FIG. 11 is a conceptual diagram of an information processing system S6 according to the sixth embodiment. As shown in FIG. 11, the information processing system S6 according to the sixth embodiment may include a collection device 400 in addition to an information processing device 60, a wearable device D6, a device reading device 300, and a camera CAM.

[6-2: Configuration of Information Processing Device 60]

[0098] The configuration of an information processing device 60 in the sixth embodiment will be described with reference to Fig. 12. Fig. 12 is a block diagram showing the configuration of an information processing device 60 in the sixth embodiment.

[0099] As shown in FIG. 12 , the information processing device 60 of the sixth embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 20 of the second embodiment to the information processing device 50 of the fifth embodiment. Furthermore, the information processing device 60 may include a communication device 23, an input device 24, and an output device 25, similar to the information processing devices 20 to 50. However, the information processing device 60 does not necessarily include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 60 of the sixth embodiment differs from the information processing device 20 of the second embodiment to the information processing device 50 of the fifth embodiment in that the association unit 211 of the calculation device 21 further includes a fourth matching unit 6114. Other features of the information processing device 60 may be the same as at least one other feature of the information processing device 20 to the information processing device 50. Therefore, the following will describe in detail the differences from the previously described embodiments, and will omit appropriate descriptions of other overlapping features. [6-3: Information Processing Operation Performed by Information Processing Device 60]

[0100] Next, the information processing operation performed by the information processing device 60 in the sixth embodiment will be described with reference to Fig. 13. Fig. 13 is a diagram showing the flow of the information processing operation performed by the information processing device 60 in the sixth embodiment.

[0101] As shown in FIG. 13, the image acquisition unit 215 acquires an image of the person to be authenticated wearing the wearable device D6 (step S20).

[0102] The biometric information acquisition unit 212 acquires fingerprint information from the collection device 400 that collects fingerprint information as biometric information (step S60). The collection device 400 may be a fingerprint reader. The first matching unit 2111 performs fingerprint authentication (step S61).

[0103] Biometric information acquisition unit 212 acquires, from collection device 400 that collects fingerprint information, collection device identification information that can uniquely identify collection device 400 (step S62). Note that steps S60 and S62 may be performed simultaneously.

[0104] The fourth collation unit 6114 detects in-image collection device information presented by the collection device that can be reflected in the image and can uniquely identify the collection device 400 (step S63). The collection device 400 may present its unique ID by a method that can be reflected in the image, such as light, characters, a one-dimensional code such as a barcode, or a matrix-type two-dimensional code.

[0105] The fourth verification unit 6114 performs collection device verification as the fourth verification using the collection device identification information acquired in step S62 and the in-image collection device information detected in step S63 (step S64).

[0106] The second matching unit 2112 detects in-image attachment identification information presented by the wearable device D6 that can uniquely identify the wearable device D6 and that appears in the image acquired in step S20 (step S34). The attachment identification information acquisition unit 213 acquires, from the wearable device D6 worn by the person to be authenticated, attachment identification information that can uniquely identify the wearable device D6 (step S24). The second matching unit 2112 performs attachment matching as the second matching using the in-image attachment identification information and the attachment identification information (step S35).

[0107] The third matching unit 2113 detects joint position information indicating the positions of the joints of the person to be authenticated included in the image (step S65). The third matching unit 2113 detects information indicating the position of the collection device 400 included in the image and wearing position information indicating the position where the wearable device D6 is worn on the person to be authenticated included in the image (step S66). The position of the collection device 400 included in the image may be the position of the collection device information in the image presented by the collection device 400 detected in step S63.

[0108] The third collation unit 2113 performs position verification using the joint position information, information indicating the position of the sampling device 400, and the mounting position information (step S67).

[0109] The association unit 211 determines whether all of the fingerprint authentication, collection device matching, attachment matching, and position verification are successful (step S29). If all of the matching is successful (step S29: Yes), the association unit 211 associates the person to be authenticated with the attachment device D6 attached to the person to be authenticated based on the fingerprint authentication performed by the first matching unit 2111, the attachment matching performed by the second matching unit 2112, the position verification performed by the third matching unit 2113, and the collection device matching performed by the fourth matching unit 6114 (step S68).

When the association unit 211 associates the person to be authenticated with the wearable device D6, the authentication unit 216 authenticates the person to be authenticated using the attachment identification information (step S31).

[0110] In the sixth embodiment, fingerprint authentication using fingerprint information is performed in step S61, but instead of fingerprint authentication, authentication other than authentication using biometric features extracted from an image captured by the camera CAM, such as palm print authentication, vein authentication, or ear acoustic authentication, may be performed. [6-4: Technical Effects of Information Processing System S6]

[0111] The information processing system S6 in the sixth embodiment performs association based on the first, second, and third matching, as well as on in-image collection device information presented by the collection device 400 that can be captured in the image and that can uniquely identify the collection device 400, and on the fourth matching performed by the fourth matching unit 6114 using the collection device identification information, thereby making it possible to more reliably associate the person to be authenticated with the wearable device D6. [7: Seventh Embodiment]

[0112] Next, a seventh embodiment of an information processing device, a wearable device, an information processing method, and a recording medium will be described. Hereinafter, the seventh embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S7 to which the seventh embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied. [7-1: Overall configuration of the information processing system S7]

The authorization device 500 may be a device that performs at least one of authorization including authorization for the authenticated person to enter and exit a specific area and authorization for the authenticated person to use a specific service. In the seventh embodiment, the device reader 30 Each of the device IDs 300-1 and 300-2 may be provided in correspondence with each of the permitting devices 500. FIG. 14 illustrates a case where the information processing system S7 includes a device reader 300-1 corresponding to the permitting device 500-1, a device reader 300-2 corresponding to the permitting device 500-2, and a device reader 300-N corresponding to the permitting device 500-N. The information processing device 70 may acquire the attachment identification information from the device reader 300 and issue an instruction to permit an operation performed by the permitting device 500. When the person to be authenticated approaches the permitting device 500 that provides the service or the like that the person to be authenticated desires to use, authentication using the attachment identification information is performed, and the person to be authenticated may be able to receive the service or the like. [7-2: Configuration of the Information Processing Device 70]

[0114] The configuration of an information processing device 70 in the seventh embodiment will be described with reference to Fig. 15. Fig. 15 is a block diagram showing the configuration of an information processing device 70 in the seventh embodiment.

[0115] As shown in FIG. 15 , the information processing device 70 of the seventh embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 20 of the second embodiment to the information processing device 60 of the sixth embodiment. Furthermore, the information processing device 70 may include a communication device 23, an input device 24, and an output device 25, similar to the information processing devices 20 to 60. However, the information processing device 70 does not necessarily include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 70 of the seventh embodiment differs from the information processing device 20 of the second embodiment to the information processing device 60 of the sixth embodiment in that the calculation device 21 includes a permission unit 717. The permission unit 717 may grant at least one permission, including permission to enter and exit a specific area and permission to use a specific service, to a living body wearing the wearable device D7. Other features of the information processing device 70 may be the same as at least one other feature of the information processing device 20 to the information processing device 60. Therefore, in the following, only the differences from the embodiments already described will be described in detail, and the description of other overlapping parts will be omitted as appropriate. [7-3: Operations Performed in Information Processing System S7]

[0116] For example, the permitting device 500-1 may be a device that unlocks a door provided at the entrance / exit of a specific area. The device reading device 300-1 reads the attachment identification information from the wearable device D7 worn by the person to be authenticated who approaches the entrance / exit of the specific area. The device reading device 300-1 transmits the attachment identification information to the information processing device 70. The authentication unit 216 authenticates the person to be authenticated using the attachment identification information. The permitting unit 717 determines whether the authenticated person to be authenticated may be granted permission to enter and exit the specific area. If the permitting unit 717 determines that the person to be authenticated may be granted permission to enter and exit the specific area, it issues an instruction to the permitting device 500-1 to permit the door unlocking operation. The permitting device 500-1 unlocks the door provided at the entrance / exit of the specific area, allowing the person to enter and exit the specific area.

[0117] Furthermore, for example, the permitting device 500-2 may be a device for using a specific service. The device for using a specific service may be a device for using a service including functions and information. The service may be a function, information, etc. that can only be used by authorized persons. The device reading device 300-2 reads attachment identification information from a wearable device D7 worn by a person to be authenticated who approaches the permitting device 500-2. The device reading device 300-2 transmits the attachment identification information to the information processing device 70. The authentication unit 216 authenticates the person to be authenticated using the attachment identification information. The permission unit 717 determines whether the authenticated person to be authenticated may be granted permission to log in to the permitting device 500-2. If the permission unit 717 determines that the person to be authenticated may be granted permission to log in to the permitting device 500-2, it issues an instruction to the permitting device 500-2 to permit the login. The permission unit 717 also determines which services provided by the permitting device 500-2 the authenticated person to be granted permission to use. The permission unit 717 instructs the permission device 500-2 to permit the authentication-subject to use the service for which it has been determined that the authentication-subject may be permitted to use. The authentication-subject logs in to the permission device 500-2 and becomes able to use the specific service.

[0118] Furthermore, for example, the authorization device 500-N may be a device that unlocks one of a plurality of drawers provided in a specific cabinet. The device reading device 300-N reads the attachment identification information from the wearable device D7 worn by the person to be authenticated who approaches the specific cabinet. The device reading device 300-N transmits the attachment identification information to the information processing device 70. The authentication unit 216 authenticates the person to be authenticated using the attachment identification information. The authorization unit 717 determines whether the authenticated person to be authenticated may be granted permission to open and close any of the drawers. If the authorization unit 717 determines that the person to be authenticated may be granted permission to open and close any of the drawers, it issues an instruction to the authorization device 500-N to permit the unlocking operation of the drawer for which it has been determined that permission to open and close is permitted. The authorization device 500-N unlocks the drawer for which it has been determined that permission to open and close is permitted, and the person to be authenticated may open and close the drawer for which it has been determined that permission to open and close is permitted.

[0119] While the person to be authenticated is wearing the wearable device D7, the information processing device 70 may authorize the use of services to which the person to be authenticated is permitted by authenticating the person to be authenticated using the attachment identification information presented by the wearable device D7. Furthermore, the information processing device 70 may manage the behavior of the person to be authenticated based on the attachment identification information acquired from multiple device readers 300. [7-4: Technical Effects of the Information Processing System S7]

[0120] The information processing system S7 in the seventh embodiment can provide personal authentication with accuracy equivalent to highly accurate biometric authentication without impairing business productivity. The information processing system S7 follows the concept of single sign-on, and after a person is authenticated only once by biometric authentication, the person can be subsequently authorized to use various services by authenticating the accessory identification information corresponding to the person to be authenticated. [8: Eighth Embodiment]

[0121] Next, an eighth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described. Hereinafter, the eighth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S8 to which the eighth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied.

[0122] The configuration of an information processing system S8 in the eighth embodiment will be described with reference to Fig. 16. Fig. 16 is a block diagram showing the configuration of an information processing system S8 in the eighth embodiment.

[0123] As shown in FIG. 16, the information processing system S8 of the eighth embodiment differs from the information processing systems S2 of the second embodiment to S7 of the seventh embodiment in that the wearable device D8 further includes a detector D83. The detector D83 detects that the wearable device D8 has been removed from the living body. Other features of the information processing system S8 may be the same as at least one other feature of the information processing systems S2 to S7. Therefore, the following will describe in detail the differences from the previously described embodiments, and will omit descriptions of other overlapping features as appropriate. [8-1: Wearable Device D8]

[0124] When the wearable device D8 is attached to the living body, the first presenter D21 presents attachment identification information that can uniquely identify the wearable device D8. When the wearable device D8 is attached to the living body, the device reader 300 may write the attachment identification information to an electronic circuit of the wearable device D8.

[0125] The wearable device D8 is detached from the living body when a specific operation is performed. The specific operation may be unlocking the wearable device D8 if the wearable device D8 is attached in a locked state, or destroying the wearable device D8. The detection unit D83 detects that the wearable device D8 has been detached from the living body. The detection unit D83 may have an electrical contact that detects detachment from the living body due to unlocking or destruction.

[0126] When the detection unit D83 detects that the wearable device D8 has been detached from the living body, the first presentation unit D21 terminates presentation of the wearable item identification information. For example, if the wearable device D8 includes an active RF tag, the first presentation unit D21 may invalidate the wearable item identification information written in the electronic circuit. The wearable device D8 may have a function to ensure invalidation of the correspondence between the living body and the wearable device D8 when the wearable device D8 is detached by unlocking or destruction.

[0127] When the attachment device D8 is attached to the living body again, the first presentation unit D21 may present new identification information different from the attachment identification information. That is, the attachment device D8 may have a function to ensure that even if a third party reattaches the attachment device D8, the attachment identification information before unlocking or destruction cannot be reproduced. When the attachment device D8 is detached from the living body, the presentation of the attachment identification information is terminated, and the same attachment identification information is not presented even when the attachment device is reattached, thereby ensuring the identity of the attachment at the time of attachment.

[0128] For example, the wearable device D8 may be a disposable paper wristband including a passive RF tag. In this case, at least a portion of the electronic circuitry included in the wearable device D8 may be wrapped around the entire wristband. In this case, if the wristband is torn and removed from the arm, at least a portion of the electronic circuitry is disconnected, and the wearable device D8 permanently loses its function of presenting the wearable item identification information. In other words, in this case, when the wearable device D8 is removed from the living body, it stops presenting the wearable item identification information and cannot be reattached. [8-2: Information Processing Device 80]

[0129] When the wearable device D8 is detached from the living body, the associating unit 211 invalidates the association between the living body and the wearable device D8. When the detecting unit D83 detects that the wearable device D8 has been detached from the living body, the detecting unit D83 may present detachment information indicating this to the information processing device 80 via the device reading device 300. When the associating unit 211 acquires detachment information from the wearable device D8, the associating unit 211 may invalidate the corresponding information registered in the association information 221. In this case, for example, even when the attachment identification information acquiring unit 213 acquires identification information that is identical to the attachment identification information of the wearable device D8 that was previously attached to the living body, the identification information does not need to be associated with the living body that previously wore the wearable device D8.

[0130] When the wearable device D8 is attached to the living body again, the associating unit 211 newly associates the living body with the wearable device D8. For example, when the wearable device D8 is attached to the living body again, the device reading apparatus 300 may write new attachment identification information to an electronic circuit included in the wearable device D8.

[0131] That is, the association between the living body and the wearable device D8 is valid while the living body is wearing the wearable device D8. [8-3: Technical Effects of the Information Processing System S8]

[0132] The information processing system S8 in the eighth embodiment can keep the association between the living body and the wearable device D8 valid from the time the wearable device D8 is attached to the living body until the time the wearable device D8 is detached from the living body. [9: Ninth Embodiment]

[0133] Next, a ninth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described. Hereinafter, the ninth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S9 to which the ninth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied.

[0134] The wearable device D9 has a structure corresponding to the uneven shape of a living body. The wearable device D9 may have a mechanical structure that utilizes the uneven shape of a living body, such as handcuffs, a collar, or ankle ring, and cannot be removed from the living body unless unlocked, destroyed, or the like. As a result, when the wearable device D9 is attached to a living body, it remains attached to the living body until a specific operation, such as unlocking or destruction, is performed. An ID device with a special structure such as the wearable device D9 may be called an "ID handcuff." [Technical Effects of the Information Processing System S9]

[0135] The information processing system S9 in the ninth embodiment can guarantee the unity of the living body and the wearable device D9 in addition to guaranteeing the identity of the wearable device as described in the above embodiments.

[0136] By assigning a unique ID to each belonging, the uniqueness of the belonging can be guaranteed, at least within the scope of the amount of information that the ID can express. This uniqueness of the belonging can be significantly greater than the uniqueness of biometric authentication. It is also possible to authenticate the owner of the belonging while working without placing any burden on the owner. Workers can carry a wearable device D9 that displays a unique ID for each individual, allowing the movements of the worker to be tracked. However, belongings may be held by someone other than the owner, making it difficult to use this as a substitute for highly accurate biometric authentication in many cases.

[0137] In contrast, the wearable device D9 used in the information processing system S9 in the ninth embodiment is attached to a living body and is integrated with the living body, so it is impossible to spoof using the wearable device D9. Since the wearable device D9 is guaranteed to be integrated, it is possible to "guarantee uniqueness" and "guarantee authenticity" in the same way as biometric authentication. Furthermore, due to its integration, there is no risk of transfer to a third party, loss, or theft. In addition, there is no problem with biometric authentication, such as the burden on the living body. [10: Tenth Embodiment]

[0138] Next, a tenth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described. Hereinafter, the tenth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium will be described using an information processing system S10 to which the tenth embodiment of the information processing device, the wearable device, the information processing method, and the recording medium is applied.

[0139] The information processing system S10 of the tenth embodiment is different from the information processing systems S3 of the third embodiment to S9 of the ninth embodiment in the in-image attachment identification information presented by the second presentation unit D32. Other features of the information processing system S10 may be the same as at least one other feature of the information processing systems S3 to S9. Therefore, the following will describe in detail the parts that are different from the already-described embodiments, and will omit a description of other overlapping parts as appropriate.

[0140] In the tenth embodiment, the in-image attachment identification information may be information indicating a hash value based on at least identification information that can uniquely identify the wearing device D10 and secret information known only to the wearing device D10 and a device that authenticates the wearing device D10. The in-image attachment identification information may be information indicating a hash value based on identification information that can uniquely identify the wearing device D10, secret information known only to the wearing device D10 and a device that authenticates the wearing device D10, and the time when the wearing device D10 presents the in-image attachment identification information. The device that authenticates the wearing device D10 may be any one of the information processing devices 30 to 90. [Technical Effects of the Information Processing System S10]

[0141] In the information processing system S10 of the tenth embodiment, the in-image attachment identification information is information that cannot be generated by a third party who does not know the secret information, thereby improving the verification accuracy. Furthermore, since the information used to verify the correspondence with biometric authentication changes from moment to moment, by including information about the time in the in-image attachment identification information, the information becomes more difficult for a third party to generate, thereby improving the verification accuracy.
