Description

  The present invention relates to a technique for authenticating a subject.

  In recent years, computerization has progressed in medical institutions such as hospitals, and an increasing number of institutions have introduced electronic medical records that manage patient diagnosis information. On the electronic medical record, patient diagnosis history information, medication information, surgery information, affected part image data, X-ray image data, etc. are centrally managed, and data (information) can be easily shared and reused. Yes. In addition, with the recent increase in storage capacity, it has become possible to take a large amount of image data of affected areas and store it in an electronic medical record.

  In such an environment, a usage method is often used in which a patient is photographed using a digital camera and the photographed image data is stored in an electronic medical record as a medical record. In particular, in the field of dermatology, surgery, or nursing care, a patient's wound, surgical scar, or pressure ulcer (bed slip) is regularly photographed with a digital camera, and changes over time of the affected area are observed.

  In such a use scene of a digital camera, a doctor who has examined does not necessarily take a picture. Under the direction of a doctor, an in-hospital imaging staff or nurse or an out-of-hospital visiting nurse may take an image. In this case, it is necessary for the doctor to issue an imaging instruction including the imaging part, the number of imaging images, the imaging position, etc. in addition to basic information such as the name and ID of the target patient, and the photographer needs to perform imaging while confirming the doctor's instruction is there.

  For such usage scenes, Patent Document 1 discloses that a 3D image data of a patient is displayed on a screen when a doctor's imaging order is issued, and a doctor directly designates an imaging region on the 3D image data. A technique for issuing an order is disclosed. However, in the technique disclosed in Patent Document 1, the photographer visually confirms the identity of the patient. For this reason, there is a possibility that a medical accident will occur due to a patient's mistake. In order to prevent this, it is required to perform reliable personal authentication.

  On the other hand, Patent Document 2 discloses a technique for recognizing a patient using a face image and performing medical practice such as medical examination or medication. Patent Document 3 discloses a technique for selecting a plurality of authentication methods based on preset priorities.

Control to store in the storage unit 122 is performed. The authentication unit 137 performs patient authentication based on the authentication method stored in the authentication information storage unit 123 of the image management server device 120.

  FIG. 2 is a flowchart showing a photographing process in the photographing processing system 100 according to the first embodiment of the present invention. Note that the process illustrated in FIG. 2 is a process that is started when a doctor instructs the client apparatus 110 to perform imaging. 2 is a process realized by the CPU reading and executing necessary data and programs from a recording medium such as an HDD in the corresponding apparatus in the imaging processing system 100.

  In step S101, the imaging instruction input unit 111 of the client apparatus 110 receives an imaging instruction from a doctor. At the same time, the patient information acquisition unit 113 of the client device 110 acquires patient information, and the authentication method determination unit 114 of the client device 110 is used for patient authentication based on the patient information acquired by the patient information acquisition unit 113. Determine the authentication method to be used. Then, the client apparatus 110 transmits the imaging instruction received by the imaging instruction input unit 111 and the authentication method determined by the authentication method determination unit 114 to the image management server apparatus 120 via the network 140. . The image management server device 120 stores the photographing instruction received from the client device 110 in the photographing instruction storage unit 121 and stores the authentication method received from the client device 110 in the authentication method storage unit 123.

  In step S <b> 102, the imaging apparatus 130 reads the imaging instruction from the imaging instruction storage unit 121 of the image management server apparatus 120 and the authentication method from the authentication method storage unit 123 of the image management server apparatus 120 via the wireless network 150. . The imaging apparatus 130 authenticates the patient using the authentication unit 137. After the authentication is successful, the photographing apparatus 130 rearranges the photographing instructions and displays the rearranged photographing instructions on the display unit 135. Thereafter, when the photographer performs a photographing process in accordance with the photographing instruction displayed on the display unit 135, the photographing apparatus 130 generates photographed image data of the patient to be photographed. The imaging device 130 transmits the captured image data of the imaging target patient to the image management server device 120 via the wireless network 150. The image management server device 120 stores the captured image data of the imaging target patient in the image storage unit 122.

  In step S <b> 103, the client device 110 acquires the captured image data stored in the image storage unit 122 of the image management server device 120, and displays the captured image data on the image display unit 112 so that the doctor can view it. At this time, the image display unit 112 displays the captured image data in the order corresponding to the imaging instruction from the doctor.

  FIG. 3 is a diagram illustrating an example of an imaging instruction input by a doctor. In the example shown in FIG. 3, the imaging instruction 300 includes patient basic information of an imaging target patient such as a patient name, patient ID, age, and sex, an instructing doctor name, an imaging method, an imaging site (imaging affected area), an imaging position, Includes shooting information such as precautions and authentication methods. In the example shown in FIG. 3, a plurality of imaging regions are simply listed, but the number of images, imaging angle, imaging reason, precautions, and the like may be set in detail for each imaging region. The authentication method is automatically determined by the authentication method determination unit 114, but can be manually input by a doctor.

  FIG. 4 is a flowchart showing details of the photographing process in step S102 of FIG. Note that the processing shown in FIG. 4 is realized by the CPU reading and executing necessary data and programs from a recording medium such as an HDD in the photographing apparatus 130.

  In step S <b> 1021, the imaging apparatus 130 loads the authentication method stored in the authentication method storage unit 123 of the image management server apparatus 120, for example, into the storage unit 131 via the wireless network 150. Here, the image management server device 120 and the imaging device 130 are connected by a wireless network 150 such as short-range wireless communication or infrared communication represented by Bluetooth (registered trademark). Then, the imaging apparatus 130 authenticates the patient using the loaded authentication method. If the patient authentication is successful, the process proceeds to step S1022. In step S <b> 1022, the imaging apparatus 130 loads the imaging instruction stored in the imaging instruction storage unit 121 of the image management server apparatus 120, for example, into the storage unit 131 via the wireless network 150.

  In step S1023, the imaging device 130 selects a schema as a reference diagram from the schema (human body partial view) stored in the storage unit 131, based on the imaging region included in the imaging instruction loaded in step S1022. In the present embodiment, the reference diagram selection process is performed by the imaging device 130, but the image management server 120 selects a schema as a reference diagram based on the imaging region included in the imaging instruction. The imaging device 130 may load the selected reference diagram from the image management server device 120 as a part of the imaging instruction.

  In step S1024, the imaging apparatus 130 displays the imaging part included in the imaging instruction on the display unit 135. Here, for example, the imaging region included in the imaging instruction is superimposed and displayed on the reference diagram selected in step S1023.

  Subsequently, when the photographer selects one imaging region from the imaging regions displayed in step S1024, the imaging device 130 displays the imaging instruction loaded in step S1022 on the display unit 135 in step S1025. Here, for example, a shooting instruction is displayed superimposed on the live view image data.

  Subsequently, the photographer presses the shooting button. As a result, in step S1026, the imaging unit 134 of the imaging apparatus 103 performs imaging processing for converting an optical image of the subject (imaging target patient) captured from the lens into electronic captured image data. In step S1027, the imaging device 130 (for example, the imaging unit 134) assigns imaging information as metadata to the captured image data obtained by the imaging process in step S1026. In addition to information obtained at the time of shooting such as the shooting date and time and shooting location, the shooting information given in this step includes basic information on the patient to be shot, shooting instructions such as the shooting site, and identification of the patient. The authentication information used is listed. By adding imaging information to the captured image data in this manner, for example, the captured image data can be searched later by specifying the imaging region with a keyword such as “right elbow”, or used for patient authentication. It is possible to check the information.

  In step S1028, the imaging apparatus 130 determines whether imaging processing has been completed for all imaging regions. If the imaging process has not been completed for all imaging regions, the process returns to step S1024. Then, the imaging process 130 performs again the processes from step S1024 on the imaging part for which the imaging process has not been completed yet. On the other hand, if the imaging process has been completed for all imaging regions, the process proceeds to step S1029.

  In step S1029, the image storage control unit 136 of the imaging device 130 indicates the imaging part included in the imaging instruction shown in FIG. 3 instead of the imaging order by the operator, with respect to the imaging image data obtained by the imaging process in step S1026. In order, the image data is stored in the image storage unit 122 of the image management server device 120.

  FIG. 5 is a flowchart showing details of the authentication processing in step S1021 of FIG. Note that the processing illustrated in FIG. 5 is realized by the CPU reading and executing necessary data and programs from a recording medium such as an HDD in the photographing apparatus 130.

  In step S <b> 10211, the imaging device 130 acquires an authentication method from the authentication method storage unit 123 of the image management server device 120. This authentication method is a method determined by the authentication method determination unit 114 of the client device 110, and includes, for example, an authentication method using biometric information and an authentication method using personal information. The biological information includes, for example, a face, an iris, a fingerprint, a voice print, a palm print, a signature, and a tooth shape. The personal information includes, for example, name, age, address, permanent address, date of birth, medical history, family name and composition, and insurance card number. Note that at least one authentication method may be determined, and it is not necessary to determine both an authentication method using biometric information and an authentication method using personal information.

  Here, the authentication method determination process in the authentication method determination unit 114 will be described. First, the authentication method determination unit 114 estimates information that cannot be used for the authentication process, based on information obtained from a medical record or the like (information related to a disease). Here, the information obtained from the medical record and the like includes, for example, the above-mentioned personal information and biometric information, the name of the disease, the date and time of the last examination (at the time of imaging), and the like. Note that information obtained from a medical record or the like is not limited to the above information, and may include other information or may include only a part of the above information.

  For example, if the information obtained from a medical record or the like includes information indicating that “a mumps”, a mumps patient (subject) may swell, so the authentication process using the face Is not appropriate. In addition, since a patient with dementia or a possibility thereof may have forgotten information related to the person, it is not appropriate to use personal information such as name and address for the authentication process. On the other hand, when there is no fear of dementia and there is no person with the same name or the same date of birth in the inpatient, the accuracy when using the name and date of birth is high, so this information can be easily selected. Become. In this way, the authentication method determination unit 114 selects information that can perform patient authentication processing with high accuracy based on the patient's medical condition and situation, and the image management server device 120, for example, in descending order of accuracy. Are stored in the authentication method storage unit 123. Here, regarding the high accuracy, accuracy information of each authentication method indicated in academic papers, books, or the like may be used, or the user may arbitrarily set the accuracy. Originally, authentication processing is performed in order to prevent impersonation of a third party, so it is rare to use information that may be known by others, such as name and date of birth. However, the purpose here is to prevent patient misplacement. In this scene, there is little merit obtained by impersonation by a third party, that is, the possibility of impersonation is low. For this reason, information known by others can also be used for the authentication process. In addition, you may make it determine an authentication method based on the time interval from imaging | photography of the last patient to the present with the information which concerns on a disease.

Below, the specific example of the process of the authentication method determination part 114 is shown.
A storage unit provided outside or inside the client device 110 stores a table in which an authentication method that is not appropriate for information obtained from a medical record or the like is associated. For example, “authentication process using a face” is associated with “muffled cold” which is information obtained from a medical record or the like. In addition, all the authentication methods and information indicating the accuracy of each authentication method are recorded in the storage unit, and the authentication method determination unit 114 assigns the authentication method associated with the information obtained from the chart etc. to all the authentication methods. Is determined as an authentication method for storing a part or all of the items removed from the image management server device 120. Note that the authentication method determination unit 114 may determine only an authentication method having an accuracy of a predetermined value or more as an authentication method stored in the image management server device 120. For example, when the information obtained from the medical record or the like is “mumps cold”, the authentication method determination unit 114 determines fingerprint authentication or the like as an authentication method to be stored in the image management server device 120. The table may be a table in which an appropriate authentication method is associated with information obtained from a medical record or the like. For example, “fingerprint authentication” or the like is associated with “muffled cold”. When there is information other than “mumps cold”, the authentication method determination unit 114 is an authentication method for storing a common authentication method among the authentication methods associated with each of a plurality of pieces of information in the image management server device 120. decide.

  Next, a specific example in which the authentication method is determined based on the time interval from the previous patient imaging to the present time will be described. When information obtained from a medical record or the like includes the date and time at the previous examination (at the time of imaging), the authentication method determination unit 114 obtains the time interval from the previous time to the present time. If this interval is greater than or equal to a predetermined value, the authentication method determination unit 114 determines an authentication method to be stored in the image management server device 120 without considering, for example, a disease name, which is information obtained from a medical record or the like. This is because if the interval from the previous visit to the current visit is more than a predetermined value, the disease has improved, and it is considered unnecessary to consider the name of the disease when determining the authentication method. In this way, it is possible to reduce the possibility that high-accuracy authentication methods will be eliminated by disease names that have already been improved. For example, “mumps cold” may be improved if a predetermined interval is provided, but in the case of “dementia”, the possibility of improvement is low even if the predetermined interval is provided. Therefore, it may be determined whether or not to consider the interval from the previous examination to the current examination according to the disease name. In addition, since the number of days until improvement varies depending on the disease, the predetermined value to be compared with the interval from the previous visit to the current visit may be changed according to the disease name.

  When the authentication method is acquired, in step S10212, the authentication unit 137 selects an authentication method recommendation and an authentication method used for actual authentication processing. Here, the one with the highest authentication accuracy is selected as the authentication method used in the actual authentication process. However, when the accuracy of the plurality of authentication methods is the same, the authentication unit 137 presents all or part of the plurality of authentication methods, and the photographer may select an authentication method to be used from among them. Good. In addition, a plurality of authentication methods may be combined and presented. For example, when using a face image, as indicated by reference numeral 601 in FIG. 6, an imaging instruction is displayed on the display unit 135 of the imaging apparatus 130 to prompt patient authentication processing. When personal information is used in combination, as shown at 602 in FIG. 6, it is prompted to confirm the patient's personal information on the display unit 135 of the imaging apparatus 130 and the correct answer is displayed. The photographer authenticates the patient based on the screen indicated by 602 in FIG. When selecting a desired authentication method from a plurality of authentication methods, as shown by reference numeral 603 in FIG. 6, for example, candidate authentication methods are displayed in the order in which there is a high possibility that patient authentication will be obtained. Will be prompted to select the authentication method to use.

  When the authentication method is selected, in step S10213, the authentication unit 137 changes the setting of the photographing apparatus 130 to the setting corresponding to the selected authentication method. For example, when an authentication method using a fingerprint is selected, it is necessary to capture a fine pattern clearly, so it is desirable to capture in close-up mode. Accordingly, in this case, the setting is automatically switched to the close-up mode. When the authentication method using a voiceprint is selected, the microphone is turned on. In addition, the setting is changed according to each authentication method.

  After the setting change is performed, the photographer performs photographing and a question for authenticating the patient, and inputs the result to the photographing apparatus 130. In step S10214, the authentication unit 137 performs patient authentication processing based on the input result from the photographer. In step S10215, the authentication unit 137 determines whether the patient authentication has succeeded or failed. If the authentication is successful, the process proceeds to step S10216. On the other hand, if the authentication fails, the process proceeds to step S10217.

  In step S10216, the display unit 135 displays that the patient has been successfully authenticated, as indicated by reference numeral 701 in FIG. Then, the display unit 135 transitions to display of a shooting instruction. In step S <b> 10217, the authentication unit 137 determines whether there is an accurate authentication method remaining, that is, whether a selectable authentication method remains in the authentication method storage unit 123 of the image management server device 120. If the authentication method remains in the authentication method storage unit 123, the process proceeds to step S10218. On the other hand, if no authentication method remains in the authentication method storage unit 123, the process proceeds to step S10219.

  In step S10219, the display unit 135 notifies the user that the authentication is unsuccessful, and prompts the user to authenticate the patient using another authentication method, as shown by reference numeral 702 in FIG. Display for At this time, if there is only one or a plurality of remaining authentication methods and there is a difference in accuracy, the user is prompted to perform the authentication operation immediately, as in the screen shown at 601 in FIG. May be. Further, similar to the screen shown at 602 in FIG. 6, a combination of a plurality of authentication methods may be prompted.

  In step S <b> 10218, the display unit 135 displays that authentication using the photographing apparatus 130 cannot be performed, as indicated by 703 in FIG. 7. In this case, the imaging may be stopped at this point because the patient cannot be authenticated, or the imaging may be continued by authenticating the patient by another means under the responsibility of the photographer.

  FIG. 8 is a diagram illustrating an example of a reference diagram selected in step S1023 of FIG. The imaging device 130 holds a partial human body diagram called a schema. As shown in FIG. 8, the schema is given classification names indicating the display range on the human body, such as “whole body” 801 and “head” 802, and each classification name is viewed from the front of the human body. It holds the schema name and the schema name seen from behind. Here, only “whole body” 701 and “head” 702 are shown as classification names, but other schemas such as “right forearm” and “right palm” are required depending on the assumed shooting scene. Prepared in advance.

  FIG. 9 is a diagram showing a table used for the reference diagram selection process in step S1023 of FIG. The table shown in FIG. 9 is stored in, for example, the storage unit 131 of the photographing apparatus 130.

  The classification name 901 indicates the display range on the human body like “whole body” 801 and “head” 802 shown in FIG. Further, as shown in a schema name 903 in FIG. 9, for each classification name 901, a schema name viewed from the front of the human body and a schema name viewed from the back of the human body are stored.

  The element 905 stores the part name on the human body displayed on the schema corresponding to the schema name 903. Note that the portion stored in the element 905 does not necessarily have to be accurately displayed on the human body structure. For example, the element “right elbow” included in the “front of the whole body” of the schema name 903 should be included in the “back of the whole body” to be precise, but at the time of photographing, as shown in FIG. The elbow is bent to shoot. Therefore, the element “right elbow” is arranged on the “front of the whole body” in order to give priority to easy understanding of the display for the photographer. The number of elements 904 is the number of elements 905 (number of parts) included in the schema name 903, and the number of elements 902 is the number of elements 905 included in the classification name 901.

  FIG. 11 is a flowchart showing details of the reference diagram selection process in step S1023 of FIG. Note that the processing illustrated in FIG. 11 is realized by the CPU reading and executing necessary data and programs from a recording medium such as an HDD in the photographing apparatus 130.

  In step S10231, the imaging apparatus 130 searches for a schema name 903 including all imaging parts in the element 905 from the table shown in FIG. In addition, all the imaging | photography parts here mean all the imaging | photography parts included in the imaging | photography instruction | indication loaded by step S1022. In step S10232, the imaging apparatus 130 determines whether there is a schema name 903 that includes all imaging regions in the element 905. If there is a schema name 903 that includes all imaging regions in the element 905, the process proceeds to step S10236. On the other hand, if there is no schema name 903 that includes all imaging regions in the element 905, the process moves to step S10233.

  In step S10233, the imaging apparatus 130 acquires a classification name 901 that includes all imaging regions in the element 905. If it is determined in step S10232 that there is no schema name 903 including all imaging parts in the element 905, it means that not all imaging parts can be displayed with a schema only on the front or back of the human body. means. For example, when the table shown in FIG. 9 is searched for the imaging part {right olecranon, left elbow, right gluteal area, left patella} of the imaging instruction shown in FIG. However, the right elbow head and the left elbow head exist only in the schema showing the front of the human body. That is, there is no schema that includes all imaging regions. Therefore, the search range is expanded for the classification name 901 having a pair of schemas on the front of the whole body and the back of the whole body.

  In step S10234, when there are a plurality of classification names 901 acquired in step S10233, the imaging apparatus 130 refers to the number of elements 902 shown in FIG. 9 and acquires the classification name 901 having the smallest number of elements. This means that the minimum schema that can display all shooting instructions is acquired. In the example of FIG. 9, since there is only “whole body” as the classification name 901 including all of the imaging parts {right elbow head, left elbow head, right gluteal area, left patella} included in the imaging instruction shown in FIG. ”Is acquired.

  In step S10235, the imaging device 130 acquires the schema included in the classification name 901 acquired in step S10234 as a reference diagram.
