Description

  The present invention relates to management of image data, and more particularly to a technique for maintaining the evidence of captured image data. In particular, the present invention relates to an image management system using a digital camera and a portable terminal equipped with a communication function, and more particularly to an image management system that guarantees the evidence of a captured digital image.

  In recent years, with the improvement of digital camera performance and the emergence of portable terminals equipped with digital cameras, the number of users of digital cameras has increased. Compared with conventional analog cameras, digital cameras will be used in the future because of the advantages such as the number of images that can be shot, the ability to check the shot images immediately, and the ability to easily delete unnecessary images. It is thought that it spreads. At present, the above-described portable terminals that have more than 1 million effective pixels capable of capturing digital images that can be used as evidence have also appeared. In Japanese Patent Laid-Open No. 2003-134258 (Patent Document 1), a shutter button is pressed. Thus, a mobile phone having a function of automatically attaching information such as time, place, and sound when imaged to image data and automatically transmitting it to a storage server and an image information service system have been proposed.

  In addition, the application of electronic documents including digital images and the like is expected to be accelerated by the “Electronic Signature Law (Act on Electronic Signature and Authentication Business)”. For example, it is now possible to submit originals such as construction photographs (construction, surveying, surveying, geology, public relations, design) in construction directly under the Ministry of Land, Infrastructure, Transport and Tourism in electronic media. Furthermore, the number of scenes dealing with electronic media has increased in various fields, such as real estate companies that introduce properties on the Internet and insurance companies that handle evidence photographs of accident scenes, etc. Digital images can be obtained from paper media attached with conventional analog photos. It is expected to shift to application and data management using included electronic media.

JP 2003-134258 A

  However, since the transition to digitalization makes it easier to edit images, it is necessary to prove that digital images have not been tampered with by third parties when submitting applications and reports that contain digital images. is there. This can also be said for analog photographs, but images taken of a part of the entire subject, for example, images taken of a building site, etc., were taken of a part of a building, so I saw the image. However, there is not enough information to determine the time, place, direction, etc., and there is no evidence that the image itself is actually taken from the scene that the photographer testifies.

  However, in that respect, in the image information service system disclosed in Patent Document 1 described above, by automatically transmitting an image captured by the mobile terminal to the management server, information that provides evidence such as the shooting location and time is attached. Makes it possible to manage digital images. However, when an image reaches the third person's hand, there is no means for the third party to confirm the authenticity of the image.

  Therefore, in the present invention, in view of the above problems, a technique for ensuring the authenticity of image data including a digital image and confirming the authenticity of the image in the report when a third party obtains the report. The purpose is to provide.

  In order to solve the above-described problem, in the present invention, shooting information relating to shooting of image data is registered in association with the image data by performing predetermined processing on the image data shot by the shooting device. The predetermined processing includes inserting shooting information into the image data as an electronic watermark (digital watermark). Also included is a process of encrypting shooting information.

  In addition, the present invention includes specifying the shooting target identification information for identifying the shooting target based on the information transmitted from the server device via the network, and associating the shooting information with the image data. . Further, when the photographing apparatus applies an electronic signature to the image data and the photographing information, transmits the electronic signature to the server apparatus, and when it is determined that the electronic signature is authentic, information for the server apparatus to specify the photographing target identification information Is also included.

  According to the present invention, it becomes possible to ensure the proof of image data more strictly.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a service outline diagram of the present invention. The processing outline of the present embodiment will be briefly described with reference to FIG. In the present embodiment, the present invention is particularly applied to monitoring of construction (building) on a construction site, but is applicable to all services that handle digital images. At the building site, the person in charge of the property uses the mobile terminal 10 to photograph the subject and generate image data. In this image data, shooting information including at least one of position information at the time of shooting, time, and machine ID is inserted by digital watermark. This watermarked image data is transmitted to the management server 12 of the management contractor who undertakes management of the image data, and the management server 12 stores the image data together with the photographing information. Then, the management contractor creates a report using the stored data based on the request from the construction company. This report includes both electronic reports and paper reports. The report is then circulated to the client. In addition, when the owner receives the report, the client can browse the contents stored in the management server 12. Further, the verification center 16 can be accessed to confirm the authenticity of the report.

  Next, details of the present embodiment will be described. First, the system configuration of the present invention will be briefly described with reference to FIG. In this embodiment, a mobile terminal 10 having a photographing function connected to each other via a network, a management server 12 that stores image data and photographing information, and a detection center device 16 that enables verification of the stored image data and the like. And PC14. Here, the mobile terminal 10 is connected to the management server 12 via a wireless line, but may be connected via a wired line. The mobile terminal 10 includes a so-called camera-equipped mobile phone, but any other information processing apparatus that has a photographing function capable of photographing a digital image and executes predetermined processing according to a program may be used. Further, the mobile terminal 10 includes a device in which a camera and an information processing device are physically separated as long as predetermined processing is executed in conjunction with image shooting. That is, the camera and the information processing apparatus may be connected by a cord or the like, or image data captured by the camera may be passed to the information processing apparatus via a storage medium.

  Next, the processing content of this embodiment is demonstrated using a flowchart. First, registration of prior information for registering image data will be described with reference to FIGS. First, property information is registered as shown in FIG.

  First, in step 301, property information is registered in the management server 12 through the PC 14 used by the user. This registration is performed at the start of construction. When construction schedule data is stored in the PC 14, registration processing may be automatically performed when the construction date is reached. Further, the alarm may be issued. This property information includes a construction name that is the name of a construction site, an address that indicates the construction site address, a construction location that indicates a construction location to be photographed, and a body ID 1 to n that identifies a photographing device, that is, a body to be photographed. including. In the present embodiment, these pieces of information are included, but it is only necessary to associate the subject to be photographed with the body to be photographed.

Next, in step 302, the management server 12 assigns a property ID for identifying the object to be photographed to the property information registered in step 301 and registers it in the property ID DB.
In step 303, the property ID is notified to the PC 14.

  Finally, in step 304, the PC 14 receives the notified property ID and stores it in the storage medium.

Next, a photographer information registration process for registering a person in charge of photographing will be described with reference to FIG.
First, in step 401, the PC 14 registers person-in-charge information with respect to the management server 12 in response to an input from the person in charge. As shown in FIG. 25, the person-in-charge information includes the person-in-charge name that is the name of the person in charge, the affiliation as the organization name to which the person-in-charge belongs, the user ID in this organization, and the password. Here, the person-in-charge information may be information that can be identified by the person in charge.

  Next, in step 402, the management server 12 issues a person-in-charge ID for identifying the person-in-charge information transmitted in step 401, and registers the person-in-charge information transmitted to the person-in-charge information DB. Further, at this time, the management server 12 may associate the machine ID for identifying the portable terminal 1 (photographing device) usable by the person in charge and register it in the property DB. In step 403, the person-in-charge ID is notified to the PC 14.

  Finally, in step 404, the PC 14 receives the notification in step 403. Here, the PC 14 may be an output such as displaying the notified person-in-charge ID on a display. . Moreover, you may store in a storage medium according to the input of a person in charge.

  Next, a first example of registration processing of machine body information that is information of the mobile terminal 10 that is the photographing apparatus will be described with reference to FIG. Note that when the machine ID is registered in step 402 in FIG. 6, the processing in FIG. 7 may not be performed.

  First, in step 501, the PC 14 receives the input of the person-in-charge ID from the person in charge and calls the person-in-charge information from the person-in-charge DB. In response, in step 502, the person-in-charge information corresponding to the person-in-charge ID input in step 501 is retrieved from the person-in-charge DB and transmitted to the PC.

  Next, in step 503, the PC 14 executes a photographer registration request in response to an input from the person in charge. In other words, the person in charge requests an operation to register in the database as a photographer who can photograph. More specifically, it is requested to assign a machine ID that identifies a portable terminal that can be used by the person in charge.

  Next, in step 504, the management server 12 creates a list of machine IDs of portable terminals that can be used, and transmits them to the PC 14 in step 505. The list of aircraft IDs is arbitrarily extracted from the aircraft DB shown in FIG. Here, although not shown, an item indicating whether or not it can be used in the aircraft DB may be provided, and an aircraft ID that can use the contents of this item may be extracted. Here, using the machine number of the mobile phone as the machine ID is included. Next, in step 506, the machine ID of the portable terminal to be used is selected from the list of machine IDs transmitted in response to the input from the person in charge. In step 507, the PC 14 transmits the selected machine ID and the person-in-charge ID of the person in charge to the management server 12.

  Next, in step 508, as shown in FIG. 25, the management server 12 registers the machine ID transmitted in the column corresponding to the person-in-charge ID transmitted in the person-in-charge DB. In step 509, the management server 12 notifies the PC 14 that the registration process has been executed. In step 510, the PC 14 receives a registration notification.

  Next, a second example of registration processing of machine information that is information of the mobile terminal 10 that is a photographing apparatus will be described with reference to FIG. In the case where the machine ID is registered in step 402 in FIG. 6, the process in FIG. 8 may not be performed.

  First, the person-in-charge ID is input to the mobile terminal 10. In step 511, the mobile terminal 10 receives this input, and transmits the input person-in-charge ID and the machine ID of the mobile terminal 10 to the management server 12. Here, the mobile terminal 10 transmits the machine ID stored in the mobile terminal 10 such as identification information for identifying itself in the mobile phone. In step 512, the management server 12 registers the machine ID transmitted in the field corresponding to the person-in-charge ID transmitted in the person-in-charge DB, as shown in FIG. In step 513, the management server 12 notifies the mobile terminal 10 that the registration process has been executed. In step 514, the mobile terminal 10 receives a registration notification.

  Next, the pre-process of the photographing process will be described with reference to FIGS. In this embodiment, since the property information is associated with the photographic data (for example, watermarked), it is necessary to acquire such information. Therefore, a first example of a registered property information acquisition process will be described with reference to FIG.

  First, in step 601, the mobile terminal 10 transmits the location information of the mobile terminal 10 or the shooting target address and the machine ID of the mobile terminal 10 to the management server 12. Here, the position information is acquired by the position information acquisition unit 104 included in the mobile terminal 10. As one aspect of the position information acquisition unit 104, a GPS function is included. The address may be converted from the position information acquired by the position information acquisition unit 104 or may be input by a person in charge.

  Next, in step 602, the management server 12 executes authentication for the transmitted machine ID. For example, the determination is made based on whether or not the machine ID transmitted to the person-in-charge DB or the machine DB is registered.

  Here, when the authentication by the machine ID is performed, in step 603, the property information corresponding to the transmitted position information or address is searched from the property DB. Here, in FIG. 24, only the address is disclosed, but position information (latitude and longitude, etc.) may be held. Moreover, what is searched may output as a search result what the address of property DB and the transmitted address do not correspond. For example, the search result may be within a certain range. In step 604, the searched property information list is transmitted to the mobile terminal 10.

  Next, in step 605, the portable terminal 10 selects the property information to be photographed from the property information transmitted according to the input of the person in charge. In response to the selection, in step 606, the imaging function is activated. That is, the screen 1401 shown in FIG. 19 is displayed. As the photographing function, first, an inquiry as to whether to execute the guidance function is output. As a result, when executing, it progresses to step 801 (FIG. 11), and when not executing, it progresses to step 901 (FIG. 12). That is, when “search and shoot” on the screen 1402 of the mobile terminal 10 shown in FIG. 19 is pressed, the process proceeds to step 801, and when “shoot immediately” is pressed, the process proceeds to step 901.

Next, the 2nd example of the acquisition process of the registered property information is demonstrated using FIG.
Here, first, in step 701, the mobile terminal 10 transmits property information (list) including the machine ID.

  Next, in step 702, authentication processing is executed as in step 602. In step 703, the management server 12 searches for the property information corresponding to the machine ID transmitted from the property DB, and transmits the retrieved property information list to the mobile terminal 10 in step 704.

  In step 705 and subsequent steps, the same processing as in step 605 and subsequent steps in FIG. 9 is executed.

  Next, the guidance function will be described with reference to FIG. When “search and shoot” is pressed on the screen 1402 in FIG. 19, the screen transitions to 1403. Here, when “search at current location” is pressed, the mobile terminal 10 acquires the current location by the location information acquisition unit 104 and transmits it to the management server 12 using the communication unit 102. The management server 12 proceeds to step 802 when receiving a notification of using the guidance function from the mobile terminal 10. In step 802, information regarding the shooting location is transmitted to the mobile terminal 10. That is, in this embodiment, corresponding information is presented from the property DB. Here, the information regarding the photographing location includes image data (images 1, 2, and 3) stored in the guidance DB shown in FIG. 28 and thumbnail images thereof. Moreover, the text information (for example, display 1-3) explaining the imaging | photography location stored in guidance DB may be sufficient. Further, both image information and text information may be used. In this embodiment, information shown on the screen 1404 is presented.

  When “Search by address” is pressed on the screen 1403 in FIG. 19, the screen transitions to a screen for accepting an address input as shown by 1405 on the screen, and accepts the input of the address. Then, the corresponding information is searched in the property DB, and the information is presented as shown on a screen 1406. Furthermore, when “Search by registration number” is pressed on the screen 1403, the screen transitions to the screens 1407 and 1408 in the same manner as “Search by address”.

  In step 803, the mobile terminal 10 receives the presented information regarding these shooting locations, and proceeds to step 901.

  Next, image capturing and registration processing of the captured image will be described with reference to FIGS. First, a first example of registration processing will be described with reference to FIG.

  First, in step 901, shooting is started. That is, by pressing the “shoot” button on the screen 1409 of the mobile terminal 10 in FIG. Next, in step 902, the mobile terminal 10 inserts shooting information regarding shooting into the shot image data. In this embodiment, first, position information indicating the shooting position using the position information acquisition unit, time information indicating the shooting time using the time information acquisition unit 104, and shooting direction using the direction information acquisition unit 107 are shown. Get direction information. The direction information acquisition means can detect the direction in which the mobile terminal 10 is facing, such as a so-called gyro. Next, the acquired position information, time information, direction information, the machine ID and property ID of the mobile terminal 10 are inserted into the image data using a digital watermark. Here, the machine ID used by the portable terminal 10 is used. The property ID is the property ID selected from the property list in step 605 or 705.

  In this embodiment, the position information, time information, direction information, the machine ID and the property ID of the mobile terminal 10 are used as shooting information. However, the shooting information may be information related to shooting, and is not limited thereto. In addition, the person-in-charge ID is also included. Moreover, at least one of these may be sufficient.

  Furthermore, in this embodiment, shooting information is inserted using a digital watermark technique, but other methods may be used. For example, the photographing information may be encrypted and associated with the image data. Further, the shooting information may be hashed. Any method may be used as long as image data and photographing information are associated with each other in such a form that image data or photographing information cannot be easily altered, or when image data or photographing information is altered.

  Next, the portable terminal 10 stores the image data in which the shooting information is inserted in Step 903 and transmits it to the management server 12 in Step 904. Note that step 903 may be omitted. Here, step 904 displays the registration screen 1410 of the mobile terminal 10 in FIG. 21, and when “Register now” is pressed (selected), data is transmitted. Then, the screen transitions to 1411. When “continue shooting” is pressed on the screen 1411, the screen returns to the screen 1410 after shooting (screen 1409). When “Register later” is pressed on the screen 1410, the screen transitions to a screen 1412 in FIG. Here, if “continue shooting” is pressed, processing (screen transition) is performed in the same manner as the screen 1411. If “not registered” is pressed, the screen transitions to a screen 1413. Further, when “image registration” is pressed on the screen 1401 in FIG. 19, registration of the image data “registered later” in FIG. 21 is performed according to the screen transition of the mobile terminal 10 shown in FIG. When “Register image” is pressed, an image list screen 1414 of FIG. 23 is displayed. If one of the displayed images is selected, the screen transitions to a screen 1415. If “Yes” is pressed, the image data corresponding to the management server 12 is transmitted. Then, the screen transitions to a screen 1416. Thereafter, when “continue registration” is pressed on the screen 1416, the screen returns to the screen 1414. When “Register all” is pressed on the screen 1414, image data that has been captured and has not been transmitted is transmitted.

  Next, the management server 12 extracts the property ID from the image data transmitted in step 905. Here, the mobile terminal 10 may transmit the image data in association with the image data instead of inserting the property ID.

  Finally, in step 906, the management server 12 registers image data for each property ID based on the extracted property ID. As a result, the image DB shown in FIG. 27 is created.

  Next, a second example of registration processing will be described with reference to FIG. In the second example, processing such as digital watermarking is executed on the management server 12 side. First, the mobile terminal 10 executes the same process as in step 901 in step 907.

  Next, in Step 908, the mobile terminal 10 applies an electronic signature to the captured image data and the captured image information regarding the captured image data. In the present embodiment, as in step 902, position information, time information, and direction information are acquired.

  Next, an electronic signature is applied by associating the acquired position information, time information, azimuth information, the machine ID and property ID of the mobile terminal 10 with the photographed image data. Here, the machine ID used by the portable terminal 10 is used. The property ID is the property ID selected from the property list in step 605 or 705.

  Next, the portable terminal 10 stores the image data and the photographing information that have been digitally signed in Step 909 and transmits them to the management server 12 in Step 910.

  Next, in step 911, the management server 12 executes a process for confirming whether the electronic signature applied in step 908 is valid, that is, a predetermined one.

  In step 912, the management server 12 inserts the position information, time information, direction information, machine ID, and property ID to which the electronic signature has been applied into the image data using a digital watermark. Here, the same processing as step 902 is executed. Finally, image data is registered for each property ID as in step 913.

  Next, a third example of registration processing will be described with reference to FIG. In the third example, the property ID is given on the management server 12 side. First, the mobile terminal 10 executes the same processing as in steps 901 and 907 in step 914.

  Next, in step 915, the mobile terminal 10 executes the same electronic signature process as in step 908 with the data excluding the property ID. In step 916, the data with the electronic signature is stored, and in step 917, the data is transmitted to the management server. Note that step 916 can be omitted in the same manner as steps 903 and 909.

  Next, the management server 12 confirms the electronic signature in step 918 as in step 911. In step 919, a corresponding property ID is issued. The property ID is specified using the shooting information transmitted from the mobile terminal 10. For example, the location information and the address of the property DB are compared and specified. Further, the transmitted machine ID may be used for this comparison.

  Then, in step 920, the shooting information is inserted into the image data using the digital watermark as in step 911, and is registered for each property ID in step 921.

  Next, a process for registering image data in the verification center 16 will be described with reference to FIG. In this embodiment, the verification center 16 and the management server 12 are separate devices, but the same device may be used.

  In step 1001, the management server 12 associates image identification information for identifying image data with the image data registered in steps 906, 913, and 921. The image identification information includes property ID + registration time, property ID + photographing time, and the like. Further, the shooting information may be image identification information, a registration order number, or a random number (information). Then, the management server 12 transmits the image data to the verification center 16.

  Finally, the verification center 16 performs predetermined processing on the transmitted image data and image data, and registers a uniquely determined value. For example, hashing is performed on the image data. Note that the image data and the image identification information may be received from the management server 12 and registered with the management server 12 in duplicate.

  Next, processing relating to use and use of registered image data will be described with reference to FIGS. First, image editing processing will be described with reference to FIG. Image editing includes, for example, creating a document (report) including an image.

  First, an editor PC that is used by an editor who performs editing and is connected to the verification center 16 or the management server 12 via a network receives a user ID and a password in step 1101 according to the input of the editor. Is sent to the management server 12.

  Then, the management server 12 performs authentication processing using the transmitted user ID and password. That is, it is confirmed whether the user ID and password transmitted to the person-in-charge DB in FIG. 25 are stored in association with each other. As a result, if authenticated, the management server 12 presents a list of registered images registered in the image DB shown in FIG. 27 to the editor PC in step 1103. Of the registered images, a list of predetermined images may be presented. This case will be described using an example in which the editor is “Taro Yamada”. The affiliation DB identifies that “Yamada Taro” belongs to “A Construction Company”. Then, it is specified from the airframe DB shown in FIG. 26 that the airframe ID of the mobile terminal used by “A construction company” is “ABC123” and “DEF456”. Then, the image data having the machine ID “ABC123” or “DEF456” is retrieved from the image DB of FIG. 27 and presented to the editor PC. In addition, a search is made from the affiliation of the person in charge “Taro Yamada”. The machine ID of “Taro Yamada” is identified as “ABC123” from the person-in-charge DB of FIG. 25, and image data corresponding to this machine ID “ABC123” You may search from image DB. Further, as a search, an editable person may be stored in the image DB in association with each image data, and the search may be performed using this.

  Next, in step 1104, the editor PC selects an image to be edited from the registered image list presented in accordance with the editor's input. Then, information for specifying the selected image is transmitted to the management server 12.

  Next, in step 1105, the management server 12 transmits the image data of the selected image to the editor PC. Here, when transmitting, a copy of the image data may be created, and this copy may be sent.

  Next, the editor PC edits the image data in accordance with the editor's editing request. Then, in step 1106, a registration request for the edited image data is received and transmitted to the management server 12. The registration request includes edited image data, a user ID, and a password.

  In step 1107, the management server 12 executes an authentication process. Here, the authentication in step 1107 may be performed based on information (not shown) indicating whether or not the edited image data can be registered, stored in the person-in-charge DB.

  Next, in step 1108, the management server 12 inserts an editing history, which is information relating to editing, with a digital watermark. This editing history includes the editor and registration time. The editor can be realized by registering person-in-charge information corresponding to the user ID transmitted from the editor PC from the person-in-charge DB. Further, processing other than digital watermarking as in step 902 may be executed. In step 1109, the image data is transmitted to the verification center 16.

  Finally, in step 1110, the verification center 16 executes registration processing similar to that in step 1103 on the transmitted image data. Thereby, the information shown in the document management DB shown in FIG. 29 is registered.

  Next, the validity verification process for verifying the validity of the image data registered in the verification center 16 will be described with reference to FIG. For example, when a report is received, this process is executed when it is confirmed whether the image data used in the report is valid. For this reason, in this embodiment, the description will be made on the assumption that the image data to be verified is stored or input by the scanner or the like to the user PC used by the user.

  First, a user PC that is used by a user who wishes to verify the validity and connected to the verification center 16 or the management server 12 via the network includes a user ID and a password according to the input from the user. A verification request is transmitted to the verification center 16. In the verification center 16, authentication processing is executed in step 1202 as in step 1102. If authenticated, in step 1203, the user PC is requested to transmit image data to be verified.

  Next, in step 1204, the user PC transmits image data to be verified, for example, image data in a report being created, to the verification center 16.

  In response, the verification center 16 extracts shooting information of the transmitted image data in step 1205. In step 1206, the extracted shooting information is transmitted to the user PC.

  Then, the user PC outputs the transmitted shooting information. Here, the user may compare the photographing information output and the description content of the report to confirm the validity, or the user PC may perform the comparison in step 1207.

  Next, a falsification presence / absence verification process for confirming falsification presence / absence will be described with reference to FIG. Here, the description will be made on the assumption that image data to be verified is stored or input by a scanner or the like to the user PC as in the validity verification processing of FIG.

  First, in step 1301, the user PC transmits a tampering verification request in the same manner as in step 1201. Then, the verification center 16 performs authentication similar to that in step 1202 in step 1302 and requests transmission of image data to be verified in step 1303. Here, the user PC transmits the image data to be verified to the verification center 16 in step 1304 as in step 1204.

  Next, in Step 1305, the verification center 16 performs predetermined processing similar to Step 1110 such as hashing on the transmitted image data. Then, this result is compared with the value registered in step 1110. The value registered in step 1110 is specified using information for identifying the transmitted image data. In step 1307, the comparison result is transmitted, and the user PC receives it in step 1308.
